"You've gotta be kidding me..." Robby sighed, staring up at the hulking machine in front of him. "Not again!"

"Look it's quite simple," Josh reasoned, gesturing for his friend's tone to soften. "It agitates matter to such a degree that it bends the very fabric of time and space, creating confusion. Matter always attempts to realign itself, so with this machine I'm able to manipulate that confusion and reform reality entirely!" By now Josh was in an all-out grin, believing every word that came out of his proud mouth.

He paused in thought, "Would you like to give it a try?"

"Uhhh..... like... I mean, what can it do? You said it can only change one species at a time, right?" Rob asked in confusion.

"Well yes, but in its current state I've only managed to alter one gender at a time. I'm hoping to improve it's capabilities later on, but for now this is as far as it goes."

"Ahhh I see. So I could change...say....Cindi Walker? Like make her hotter?"

"To put it frankly, yes, you can make your wanna-be girlfriend 'hotter', but it would also alter every other female human being on the face of the planet as well."

"Wow...that's deep stuff. How about we do something simple... like make Cindi-- err, I mean all females... a bit taller? She could use some inches." Rob's eyes burned with excitement as his perverted mind envisioned a world full of taller, sexier women.

"Oh yes, that's well within it's capabilities. Here, I'll show you how it works..." Josh leaned into the control panel and spoke directly into a large microphone. "Women, 2 inches taller."

A long, deep hum emitted from the machine, quietly shaking the basement walls in the process. The two boys felt their hearts rattle within their ribcages as the large red 'Execute' button lit up brightly before them."There ya' go! That's all there is to it! I'll let you do the honors." Josh gestured his friend towards the glowing button.

Robby pointed at the button, "This one?"

"Yes yes, that one!" Josh barked, easily becoming aggravated

"Ok, here goes!"

With the palm of Rob's nervous hand, he pushed down on the heavy button.

"How do we know when it's worki--

The lights in his head blew out, and a sea of darkness enveloped him whole. Urgency crept into his throat as a violent wave of thunder thrashed at his very core. Rob screamed desperately for Josh, but nothing came out. He panicked. Left mute as his body floated helplessly, his sense of direction was all but a distant memory. Time no longer existed. He was simply... alone.

Within a blink of an eye he was back, thrown into the conscious world where the light had been restored. Rob gasped for air as the eerie sensation of drowning passed over him.

Josh steadied his friend by the shoulders. "Its ok Rob, it's ok!"

"I forgot to tell you about the transition. Sorry about that." There was a short pause. "You'll get used to it soon enough." Josh waved his hand in dismissal over his shoulder as he turned his back on Rob..

"Wow, but for a moment there I thought we were goners!" Robby laughed half-heartedly, attempting to obscure any sign of uneasiness in his voice.

Josh ignored him and began to analyze the situation scientifically. "We requested a large transition from the machine. It was like nothing I've experienced before with the mice. If I had to guess, that empty abyss we were just in was the result of the machine taking longer to process all the information. Way longer. Normally the transition between one world to the other is nearly instant-- way faster than a conscious person could ever notice. I can only hope the AI has taught itself to be quicker the next time around"

Josh turned around to see Rob's face overcome with anticipation. Josh always could read him like a book. "And yes, because we're still alive, the machine must've worked."

Rob gasped, "So that makes Cindi 5 foot 4 now! That's not bad at all." Robby felt a rush run through his veins as his mind projected a mental image of a now taller Cindi in his mind. "Jee, it was hard enough already to try and ask her out. Now it's going to be impossible!" Rob realized.

A pair of sandals flopping against the heels of someone's pretty feet could be heard coming down the basement stairs, interrupting the two boys in their 'heated' discussion.

"You boys hungry? I made you two some sandwiches. Your mother didn't already feed you, did she Robby?"

"N-no Mrs.Robinson, t-thank youuuUUU."

Both the boys stared, dazzled by Mrs.Robinson's appearance as they reached for their sandwiches.

"My, you boys alright? You act like you've just seen a ghost!" she laughed to herself, not waiting for a response, and shimmied her way back up the stairs and into the kitchen.

When she was completely out of sight, Rob couldn't hold it in anymore and blurted out "Dude! You're mom is TOTALLY bigger! I mean-- no offense, but DAMN those 2 inches suit her well!" He took a moment to appreciate the sandwich he had just been given. And with a mouthful, "I mean *smack chew*, it's not like WOW, but she's definitely noticeably taller.*smack*"

Josh grew uneasy, knowing his best friend had been eyeing his mother. "Ok ok, I get it!"

Rob was already elsewhere, "Hey...what do you say we give the machine another go?"

"What, already?! I don't want to blow the thing up! I've put so much work into it, and I want to have a safe trip back to the way things are. Just as soon as you're done having your fun. Breaking it is not an option. We could be stuck here forever, you know."

"Oh no! Stuck in a horrible world FULL of sexy, taller girls. What will we EVER do!!" he waved his hands in horror.

...

The room fell silent as the boys ate.

Completely unaware of the lurking presence that was Denise. Josh's little sister crouched behind the stack of laundry, listening in on their every word. A secret vault had been opened, and there was no stopping the evil work now being brewed in this little girl’s mind. Now was the time to fulfill a dream that at one point could only be considered a bizarre fantasy.

A devilish grin spread across her cute and otherwise innocent face.

It was only a matter of time.

Robby chirped up an idea, "What if we made it a gradual alteration instead of an instant one? We could theoretically cause little to no stress to the machine, right?"

Josh was dumbfounded by Robby's quick thinking. "Actually...you're right. The only problem is the machine can't bring about a gradual change. We saw what happened when it took longer than a split second."

Rob was frustrated, "Why can't we just bump women up one more time then? It's not like it even matters. They'll still only be 5'8"."

"On average, Rob" Josh added.

"So what? That's still 2 inches shorter than the average man," He retaliated, "Which should be more than enough for us! Come on man..."

"No Rob, I'm not doing it." Josh stood his ground. "You can't convince me."

"Fine then. I'll do it!" Rob leapt towards the machine at lightning speed!

"ROB NO!!!"

"WOMEN 2 inches taller!" he slammed his fist onto the execute button and a brief seizure in time occurred.

Only moments later Rob continued to get pummeled by Josh's scolding.

"What the fuck have you done?! I never intended for this machine to be used as a personal fantasy device for your sick mind. Fuck!"

Rob still argued against his friend.

"Look, we've got something that no one has EVER created before! We can always reverse it, right? So what's the big deal?"

"I don't want any malfunctions to occur due to overuse! There are so many mathematical equations that you aren't even aware of that could potentially destroy our very existence! Just give me a moment before you use it next time, alright? I'm not saying we can't have some fun. I did program it with you in mind."

Rob grinned. There was the Josh he knew.

"Hah! I knew you'd come through, old buddy! So, we gonna chat sum'more or shall we bless some girls with bigger hooters!" Rob draped his arm over Josh's shoulders. Josh rolled his eyes. "Here we go again. Not a moments hesitation."

---

"Josh Robinson, you get your little fanny up here right now and clean your room!" A loud, booming voice echoed off the walls. The voice of authority roared, striking fear into the hearts of her offspring.

"Yes mom!" He squealed, running up the stairs. Rob quickly followed after him.

Denise slowly crept out of her hiding spot, examining the heavily bolted steel machine in front of her.

"How did they do it again?" Denise squeaked to herself. "Oh yea!"

She slipped up to the control panel and, with her delicate little hands, reached for the microphone. It was just out of reach. "Come...onnnnn!!!!!" She strained, using her tippy toes for the slightly added boost. "Almost...got....you!!" Her index finger scrapped against it and then finally managed to wrap around it enough to pull the bendable wire down to her mouth.

She tried to recall what phrase they used. "Oh, right!" She cleared her throat and spoke as clearly as she could into the mic, all the while her heart pounded like a dozen drums."Women, 2 inches taller!"

There was a moment of silence, and then a loud "EhhHHhh!!" Error sound. Denise slapped her hands to her ears.

"What the?"

"Voice Unrecognized-- Request Denied."

The machine began to whir down, leaving Denise in silence. Only the sound of her young startled heart kept her company in the dark empty basement.

"And make sure it's spotless, ok young man?!"

"Yes Mom!"

Mrs.Robinson had now grown quite a bit over the past hour, making her an imposing figure to adapt to. Gaining four inches to an already tall woman proved to be quite the sight. She barked orders with new found vigor at a height that rivaled Robby's 6 foot stature.

Her additional two inches of growth did not go unnoticed by the two boys either. Mental comparisons of the Mrs.Robinson that he had just seen moments before were still fresh in their mind. Now an even larger version of the mother they all acknowledged was standing right before them; magnificent as always... only bigger.

Rob began, "Dude, your mom is--

"Don't even start!" Josh cut him off.

Denise stepped silently up the basement stairs and into the kitchen, placing her weight on each foot gradually, as to not make a sound. Once out of questionable proximity of the machine, she made her way over to the commotion.

Both Robby and Josh snapped their heads towards Denise as she rested her weight against the door frame.

"What are you looking at?" She snapped bitterly.

Josh turned away from his sister, completely ignoring her. He proceeded to pick up the loose clothes scattered across the floor. Robby joined in on the collecting.

Denise stood idle, staring at the boys as they knelt down to collect the loose clothing. It was then that a thought occurred. A brilliant plan had been formed to get exactly what she wanted.

There was a tap on Rob's shoulder.

"Hey Robby, can I talk to you in the other room for a second? Pleeeeaaaasseee?" She leaned in with the biggest puppy dog face she could muster, and Robby, who was a fool for any female, nodded with a dumbfounded expression.

"What's up?" Rob said plainly, staring down at the petite girl before him.

"I uhhh," She hesitated, playing with her fingers. "I couldn't help but overhear you two talking downstairs.", searching for the right words.

"Can it really do what Josh says it can do?" An expression of extreme hopefulness sprayed across her face. She held her arms up to her chest, clasping her hands together.

Rob couldn't help but feel guilty about lying. She looked genuinely innocent. Bah! Why not, he figured.

"Yea, but it's still experimental." Rob responded with a casual tone, in an attempt to negate any excitement she might get from hearing him answer honestly. Sadly, it did not work.

"D-Do-you-think-you-could-help-ME-use-it?" She blurted out.

"I dunno, Denise. That doesn't sound like such a good idea."

"Oh come on...what harm could it do!? You'd only be helping me out, what's wrong with that? Plus you'd be giving yourself more to look at." She winked, knowing Rob all too well...

Rob grew flustered with conflicted thoughts.

"Alright...but only this once, ok? I don't want Josh finding out I'm using his machine again without his permission."

"Thank you thank you thank you!" Denise jumped up and down with excitement.

Little had Rob known that this decision would forever change his life.

It didn't take long before Robby found himself standing before the giant steel machine once again.

"What exactly did you want changed anyways?" Rob asked curiously.

"Well I don't know. I guess I just want to become prettier." She admitted.

"Uhh Denise, I'd hate to break it to you, but I don't think the machine can do that. Plus it can't work on only one person."

Denise appeared unnerved, still the confident young spirit. "Well, it couldn't hurt to try, could it?"

Robby obviously knew nothing about the machine, so naturally everything she said felt safe within a reasonable doubt.

"Yea, I guess not."

"Then let's do it! I want to become as big and as beautiful as Mom! Start it start it start it! Please!"

"Ok ok, Here I go."

"Denise, more... beautiful?" Rob pushed and held the execution button down.

Robby stared at Denise. At first there was nothing, but soon he could make out small changes throughout her body.

Her small, delicate 4'7" frame began to creep taller and taller. 4'8, 4'9"...Rob panicked.

Involuntarily, he let go of the button and the growth immediately stopped.

"Hey! What happened? Why'd you stop?" Denise opened her eyes and looked at Robby in question.

"Oh, uhh, sorry. I just thought this only worked on lots of people... not just... nevermind. " He cleared his mind and continued.

Slowly her body began to expand outwards, inching higher and higher just as before. 4'10". Small buds for breasts began to form on her flat chest and the beginning of what looked like an hourglass figure began to take form. 4'11".

Robby reasoned with his mind, "Yea that should be more than enough to make her happy." he thought to himself. How generous.

"Awww.." Denise sighed, and Rob was taken aback by her reaction.

"What? Denise, that's enough. You've grown 4 inches taller already and that's a lot! I mean, look at you!" he gestured towards her chest.

A frown formed over her face, but a look of satisfaction hid beneath her youthful skin. She was extremely pleased with the gift she had just received...but she wanted more. She needed more. There had to be a way.

Rob couldn't help but scan the more subtle changes her body had undergone. Her complexion was clearer and her skin looked much richer and smoother. It was one thing to have clearer skin but her otherwise underdeveloped jaw line had begun to take a more feminine shape as well, presenting her face more lavishly. And her eyebrows, they elongated and became fuller, giving more definition to her overall beautiful brunette head.

"You like?" She teased Rob as she caught his jaw-slack stare.

Rob twitched.

"I-I was..."

"It's alright, I know I changed a lot."

Denise walked over to Robby and gave him a hug.

"Thank you."

The sensation of a slightly larger figure than he last remembered, pressing up against Rob's body, was too much! He felt his junk begin to stir. Denise wiggled herself comfortably against his frame, resting her head against his chest, and allowed her tiny, newly formed breasts to press into his stomach.

"You know, it would REALLY make me happy if I was just a little bit taller, Robbyyyy."

She wrapped her arms around him even tighter, making sure he could feel every inch of her.

"I could be SO sexy, Robby." She got up on her toes and rubbed the top of her head on the underside of his chin.

She persisted, "Just a little bit is all. It would be for you after all...I don't necessarily need it for myself."

"Nnn—Alright! Just a little bit though!" Rob snapped, shifting away from her.

"Yay!!!" She squealed with joy, jumping up and down in her school outfit. “This is too easy.” she chuckled internally.

Robby placed the palm of his hand on the button once again, preparing to make this little girl grow even bigger yet again. He didn't want to do this...but his male testosterone was urging him forward. Denise stood eagerly next to him, waiting for him to begin changing her once again. "Make me grow, Robby! Make me grow!"

*Beep*

Immediately, the growth took effect once again. 5'0"..

Rob watched as her entire body seemed to blossom in front of him like a spring flower. It appeared as if she was going through puberty a second time at 18 years old! Sections of her thighs tightened and her hips widened right before his eyes. Still, she grew.

5'1", 5'2". She was beginning to look more attractive by the second, carrying a nice set of B-cups on her frame while still maintaining a fairly youthful face and figure. Rob felt his heart begin to flutter. Her beauty was intimidating. Luckily for her, her school uniform was growing along with her as reality changed. Her burgeoning bust began to look more and more enticing by the second, and Rob was finding it hard to restrain himself from leaping onto her immediately.

They continued to expand, larger and larger, reaching an even larger B. 5'3". "Just a little more, Denise" Rob warned Denise.

5'4". Denise repositioned herself, planting her feet more firmly on the ground.

"Ok, that should be more than enough to please you Deni--

Rob began to shift his weight away from the machine, but Denise slapped her hand onto his hand, forcing the button down for longer!

"No!! Not yet!! I still want more!!!" 5'5", 5'6".

"Denise, NO! STOP!" Rob struggled to slip his hand away, watching as she continued to blossom bigger and more beautiful by the second. "NO, DENISE!!!!!" Her strength was only increasing, making it more difficult by the second to pull his hand away. His hardon distracted him as her face began to become intoxicatingly gorgeous. Through his pants, his dick slid down her lengthening body until it passed her hips and pressed into her succulent thigh. His heart raced.

5'7" "DENISE, THATS....EEE.....NUFF!!!!" 5'8"

Rob threw his entire body in the opposite direction, finally managing to pull his hand out from underneath hers. The button remained pressed down with her hand, but the machine whirred to a stop, and the room fell silent.

“Oh… darnit.” pouted Denise.

"I'm so lucky that thing only responds to Josh and I," Rob thought, still on the floor from the struggle.

Robby lifted his gaze, ready to scream and yell and kick at Denise, but instead he found himself mute at the sight of Denise's new and improved figure.

There she was, standing taller than ever with a pair of large C-cup breasts proudly on display for the world to see. She immediately struck a pose, still in her school uniform, thrusting her shoulders back and adjusting her new miniskirt that was replaced from her long pants just moments ago.

"You...You...You...." Rob found himself dumbfounded as he stared at his creation.

"You s-shouldn't have done t-that, D-Denise!", finally catching his breath, "Look at you! You've overdone it!"

And look she did. With her hands, she pressed her large breasts down as she peered down and over her ample charms, revealing a firm, flat stomach and long, shapely legs.

"No...I think I did just about right. Thanks Robby!" She walked towards him and helped him up onto his feet, exposing a very healthy amount of cleavage in the process.

"Yea....whatever." Rob huffed, slightly embarrassed from the experience.

"Awww...come on now. It's not that bad. See?" She scooted closer to him, still not matching him in height, but now much much closer. The top of her head meeting his eyes.

His brow was furrowed, "Yea....I guess not. But you still played a very dirty trick on me, Denise. I trusted you."

"I know I know, I'm sorry." Denise feigned understanding. "You'll get over it."

"I wonder what Mom will think." She pondered to herself.

Almost like a psychic, Josh screamed down to his little sister. "Mom left to go get her hair donnnnnnnnnnne! She said she'll be back in a few!"

"Kay!!!", Denise screamed back, twice as hard.

Quickly, she ran up the stairs, eager to see his brother's reaction to her gigantic growth spurt. Her breasts wobbled securely against her tight uniform as Robby followed silently behind her.

Rob found Josh sprawled on the couch, watching his favorite action movie for the fifth time.

"Hey, there you are! I was beginning to wonder where you left off to. Care to watch with me?" Josh offered. Without so much as a response, Robby hopped into a chair beside him and immediately found himself immersed in the high-speed action-packed film.

"That's strange," Denise thought "his mouth didn't open wide or anything! Maybe I've always been this buxom and beautiful to him." She snickered. "Now would be the perfect time to call up the girls and let them know of my new discovery!"

Evening rolled in and a few ultra-fake car crash scenes and a kung-fu fight later, there was a doorbell at the Robinson's residence.

"I'll get it!" screamed Denise.

*Thump thump! Thump thump!* The sound of Denise sprinting towards the door in her pajamas and white socks filled the room.

Within moments the entire house was quickly filled with girlish gossip and greetings, "Hi!!!!' "Hey Jeri!" "Yea, I'm good! You?" "Mhmm, I KNOW!" "Oh my god, really?" "No, SHE DID NOT!"

Josh and Robby grabbed nearby pillows to cover their ears.

"Come on in you guys," spoke Denise "you've met my brother and his best friend, of course."

"Hi..." "Hey..." "Nnn.." was all that left the 3 new girl's mouths as they exited out of the living room.

Denise had only just turned on the basement light when Jennifer leaned in anxiously, "So what's the 'OMG amazing' news you HAD to tell us about?"

"Shhhh." Denise held up her finger, "Don't let the them hear you. Follow me!" She gestured, stepping down the stairs quietly. Katie, Jennifer, and Jeri all followed her in suit, stepping as silently as can be.

Once safely out of earshot, Denise relayed all the events that had occurred. The girls were in shock, speechless with mouths agape.

"No way..." Jeri finally spoke.

"That's impossible, girl." Jennifer added.

"I'm serious guys!" Denise urged, "I'm not lying!"

"Then prove it to us." Katie spoke.

"Of course. That's why I brought you guys here in the first place!" Denise grinned devilishly. "I'll be right back!"

And up the staircase she went, towards her same gullible target.

"Oh Robbbyyyy!!" a high-pitched whistle-of-a-tune echoed off the walls.

"Huh?" Robby turned, looking over his shoulder towards the kitchen. There Denise stood, right by the basement door gesturing him forth.

Robby rolled his eyes as he got up and headed towards her.

"Yea?" A simple, irritated response coming from Rob.

"The girls and I wanted to play a little game together and I was wondering if you'd like to join us. You in?"

"Uh...I was kinda in the middle of a movie, but...." His teenage testosterone began to boil, "w-what kind of game?"

"I don't wanna tell! You're gonna have to find out yourself!"

"Ok... but no funny business, alright?"

"Sure sure!" Denise quickly tugged on Robby's shirt, pulling him down the endless dark stairs.

Fumbling down the stairs Rob spoke, "Wait-- your bedroom's that way!"

Denise grinned knowingly, "Yea, but the girls are down HERE!"

A cold sweat spread through him faster than ever before.

"Hey Robby!" the girls chirped innocently.

A moment of brief observation was called for as Rob first laid eyes on each of the girls.

Jeri was an amber: a luscious combination of a brunette and a redhead. Her face was sprinkled with tiny freckles covering her cheeks, which accentuated her big golden brown eyes. She was slightly less developed than the other girls in the room and was the shortest at 5'2, but she still radiated with such innocence that intoxicated the nearby air. Little had Robby known, beneath that doll of a face lay a burdened soul seeking revenge and was anything but innocent. He took a few moments longer before turning his gaze towards the next broad.

Katie was the one that stood out the most. Her chest stood high, filling her scoop-neck T-shirt abundantly to the point of near bursting. Puberty had been kind to his girl. Rob admired her the most as she appeared to be filled with more then enough juicy female flesh to satisfy the average man. That topped with a head full of bright blonde hair, she was a hard token to beat. Her body simply screamed sex.

Jennifer was a Hispanic girl standing around the same height as Katie at around 5'5". Her face was obviously her best trait at first glance, however she carried a nice pair of C-cup juggs and an ass that could only best be described as mediocre. She had very distinctive eyebrows though. They were thick and long and followed the arc of her eye perfectly, giving her an expression of determination. Rob took it in as an openly exotic thrill.

"So, we've all been thinking," Denise began, "that maybe we could all play a fun game together."

"L-Like what?" Rob answered nervously, yet still excited.

"Well.." Denise trailed off, thinking. She turned towards the group of giggling girls, in thought.

"How about we play with this Machine here?" She rested her hand on the cold steel.

Robby was no longer awkwardly smiling nor nervous. His entire expression had flip-flopped within a blink of an eye.

"Now Denise...we just discussed that there would be no funny business.."

"I know I know." Denise attempted to defuse the fire before it started, "but it'll only be temporary! We can change things back as soon as we're done. No biggy. Josh won't even know we've touched it."

"I dunno..."

"Come on, Robby!!"

The other girls joined in on the guilt-trip.

"Yea, come'on Robby!"

"It's just for a little while!"

"There's nothing to worry about."

Robby sighed, "Well...I GUESS it's ok as long as we change EVERYTHING back in the end."

"Yea of course!" Jeri exclaimed.

"Yay!" cheered Katie, grabbing and squeezing Jeri between her big boobies.

"What did you have in mind?" Rob asked, feeling the all too familiar sentence being uttered by him once again.

"Ok here." Denise shoved a black bandanna towards him, "Wrap that around your eyes, and make sure not to look!"

"Uh-hhh, alrighhtt." Rob was really unsure of what he got himself into now, but still apprehensively agreed, being pressured by the opposite sex surrounding him."N-now what?"

"Ok. Now, here." Denise grabbed his shoulders, which were easily about level with her eyes, and guided him so that the machine was at his side. Denise readjusted the microphone near his mouth.

Denise gestured the girls to encircle him.

"Alright, I want you to speak into the mic: 'Men, 2 inches shorter.'"

"What!?!-- No, I'm not doing that!" Rob fumbled with the bandanna, desperately trying to remove it and whacking the microphone out of his way in the process.

From behind, Denise threw her arms around him, in attempt to calm him. Her large breasts rubbed up and down his back purposely.

"Come on Robby, it's just for fun. No harm's done. We just want to see what it looks like to see you just a little bit shorter, that's all. Is that too much to ask? Who knows, you might even like it!" Denise grinned up towards Robby's red face, pressing those large breasts of hers up against his body.

Rob paused, mid struggle.

He said nothing, standing paralyzed from the effects of the female body. Then, without warning, "Men, 2 inches shorter." and he pressed the button.

The effects were instantaneous.

"Oooh, I've gotta say Robby, you look a lot more handsome as a shorter man." Denise spoke from behind.

A few shy giggles escaped the other girls beyond his blindfold.

"Oh my god that was a amazing!" Jeri squealed, coping a feel on his shoulders in the process. "He looks so cute!" Her hands felt… different.

"Wow..." Jennifer and Katie leaned closer, joining in on the curious fondling of Robby's body.

"Shall we try for one more time, girls?" Denise inquired.

"YES!" All three girls screamed in excitement.

"Ok ok, calm down. We have to see if it's ok with Robby first. Robby?" He removed his blindfold just in time to see Denise lean in towards him once again, using her assets to their full advantage. "Is it ok if we take our little game a tiny, itsy bitsy bit further?"

He could feel her breasts weighing down on him now. They were larger than he remembered, but his vision was still obscured by the bandanna. All he could do was feel them, through the thin material that barely separated him from a skin-to-skin contact with her fresh, youthful mammaries. Those soft, plump mounds rubbed up against his back once again. Every second that passed hindered his reasoning and judgment further. Every girl he looked at felt more alluring now that he was shorter.

"Ok, b-but only once more. I don't want to become a m-midget, even if it is only temporary."

"Alright alright, " Denise waved the stern statement away, "just press the button already!"

*Click*

There was some shifting coming from the group of girls, but they were silent. Rob waited for a response, but all he could hear was what sounded like suppressed laughter.

"So?" Robby asked curiously, still blindfolded.

"So what?" Denise responded "Nothing happened. You missed the button." The girl's pajamas created soft shifting noises in the room. He felt someone’s hand wrap around his forearm. This girl’s thumb was stroking his arm in circles, encouragingly.

"You sure? Oh jeez, sorry you're right!" Robby's gullible mind had caught him again.

Without worry, he pressed the button for the third time.

*Click*

"How about now--

"Oh my god, he's so cute now!" blurted out Jeri, leaning in against him. Her hair swept across his face, filling his nostrils with her fresh fragrance. Rob couldn't help but notice the feeling of her body up against his. It felt...more solid. Tiny Jeri was...solid? This couldn't have been the small, frail Jeri he knew.

"Jennifer?" Robby spoke in question.

Jeri giggled, "No silly, it's me, Jeri!" she leaned in and gave Rob a big smooch on the cheek. "Can't you tell by my non-existent boobies?" She giggled, grabbing his hand and rubbing it all over her chest.

In reality, they weren't that small. They were smallish Bs after all. They were just small in comparison to the rest of the girls in the room, all hefting at least full C cups. But compared to Robby's new stature, Jeri's bosom was still nothing short of amazing.

Robby flushed bright red. He felt her hard nipples against the back of his hand. That in itself was beginning to give him a hardon, but luckily Denise threw off his focus.

"So Robby, before we remove the bandanna, I say we make one more little adjustment."

“What?! No way Denise! You said--” Robby felt his face sink into a sea of cleavage. His frustration and irritation melted away as her soft warmth pressed into his cheeks. It was obvious Robby wasn't looking forward to what she had in store next, but there was no changing Denise's mind now. She was stronger, faster, and more attractive than any woman he's seen before!

"I want you to make us bigger.”

“B-But Denise… I already made you--”

“Not just me silly. All women.”

"I-I don't know Denise." He spoke towards the voice, still bathed in a sea of darkness. "That doesn't sound like such a good idea."

She simply replied "Trust me, you'll like it." and shoved the microphone towards his face.

Rob's mind began to convince itself, "I guess two more inches won't hurt. After all, there's more to look at once it's complete!" he reasoned. That was a good enough reason for him.

"Women, 2 inches taller!"

Rob tore the blindfold away from his eyes just as the process began to alter the girls in front of him. What he didn’t realize was how huge they already appeared to him!

The girls gasped as they basked in this unknown energy coursing through their bodies. With eyes agape, Rob watched as all four girls began to slowly stretch taller in their pink and purple pajamas, slowly becoming more and more intimidating with each passing second. Robby stared into Denise eyes, already 8 inches above his own. He couldn’t believe that very soon her chest would almost be eye level with him.

They continued to grow and little Jeri wasn’t looking so little anymore. After all these changes, she already rivaled Robby’s 5’2”. Now, with an innocent grin spread across her face, he watched as her head of amber hair began to creep up higher and higher. Her face glowed with excitement as her eyes could no longer lock straight into his own. Jeri took her new favorite man into her arms as the process continued around him.

"Mmmmm," a moan escaped from her lips. "You sure are getting cuter by the second, Robby!"

The rest of the girls were in the same situation. Encircling Rob, a barrier of womanly flesh slid closer and closer to his own with each passing moment. He felt shivers run down his body from the experience.

It appeared Jeri had stopped growing first, now having to only slightly tilt her head down to look Robby in the eyes. She smiled at him, eyes aglow with new found authority. She let his hardon tap against her thighs.

All the while Rob watched as mere inches away his straightforward gaze met with Katie's face. "They're all getting so tall...", Rob thought. “Too tall!’

He felt something brush up against his chest, slowly dragging upwards, and he looked down. Katie followed his gaze and found her twin peaks had been touching him while they grew! "Oopsie! Sorry about that, little man." She giggled, "I guess I don't know my own size anymore!"

The process began to wain and the girls had appeared to stop growing, though the effects it had on Robby were still very apparent. His expression was mute from the event.

"I think we broke him." Jennifer exclaimed, laughing.

He couldn’t take it any longer. He was in physical pain after witnessing what most men would consider a living heaven. Robby screamed for release, allowing his innermost primal sexual instincts and urges to run loose. His desires grew tenfold as their hands rubbed against him and their bodies bumped into his own. His cravings began to manifest inside of him. He wanted-- no-- he NEEDED more!! His eyes rested once more on the heavily gifted blonde. He licked his lips as he saw one of her protruding nipples through the T-shirt, obviously braless.

"I think he likes the new you, Katie," Jeri chirped. "He's staring at your big boobies!" she grinned.

Rob did not speak, his brain rapt with desire from the immensity of the chest heaving right before him, her breathing causing them to swell and shrink before his very eyes. More...he craved them.

With one swift gesture, he reached out for the microphone and spoke quickly and clearly into it, "Women Breasts 1 Cup Size Bigger!" and slammed, arms unbent, on the all too familiar big red button.

*Bon!* The changes occurred within the blink of an eye.

The girls gasped as they all looked down at their pajama-masked breasts. In unison, their boobs jiggled outwards, shaking up and down from the increased weight of womanly flesh now hanging so alluringly from them.

Denise snapped her gaze away from her recently increased bust just in time to see Robby press the button once more.

Their breasts sunk closer to their belly buttons but maintained their beautiful shapes. He watched, fixated as their nipples dragged against their pajamas, which naturally enlarged to accommodate this new world of more well endowed women. Rob’s eyes glazed over as a wave of realization swept over him. In this world, the average cup size for women was a D.

“What have you done!?” Kate screamed, staring at her massive F-cups resting beautifully against her chest. “I kinda like it.” Jeri chimed in as she hefted her newly gifted Ds.

Jennifer looked up from her latino E cups with a sour expression. “What gives you the right to change our bodies against our will?!”

Rob heard nothing. His eyes were focused on her creamy chocolate cleavage spilling out of her pajamas.

“For the lust of all mankind!!” Rob slammed onto the button for the third time!

Something wasn't right though. Something had gone terribly wrong! The world froze around him and a giant rumble began to shake the ground he stood on. The giant machine he had become all too familiar with began to ripple, like a disturbance on the surface of a pond. Suddenly the machine became heavily distorted, vibrating and stretching in ways that Rob never knew possible. Then, within a blink of an eye the machine had disappeared-- just like that. There was no sign of it.

Rob rubbed his head. What happened?

He looked around the room. There was no sign of the girls or the machine. They too had vanished into thin air. Things had suddenly become all too strange. Amidst the confusion, Rob cautiously climbed the basement stairs, unsure of what awaited him on the other side of the basement door.

The kitchen floor sparkled taintlessly as Rob made his way out of the basement. He caught the tip of Josh's head poking out from over the head of the couch, still sitting by the TV. How strange...

"Josh?" he said, making his way over to him.

"What's up bud? You get those drinks yet?"

"Huh? Oh, I uh.." His mind was completely cluttered. What the hell was going on?!

"Sorry, no, I forgot. I'll go get them now." Walking towards the refrigerator, Rob had only just realized that he hadn't regained his stature back, and neither had Josh. Rob's mind calculated, "That must mean..."

He grabbed two cans of soda and began to make his way back. Rob wondered what could have changed.

"Man! It took you long enough!" Josh complained, snapping the can open with lightning speed.

"Yea, sorry 'bout that. I was a bit... distracted."

Robby sat down and joined Josh, paying little to no attention at what was on TV.

Moments later, the soft rustling of a key caused the two boys to turn their heads towards the direction of the sound.

"I'm home!" Mrs.Robinson announced.

"I bought you boys some food. Hopefully it's enough for all of us. I swear, that girl keeps getting bigger and bigger everyday now!" Rob assumed she was talking about Denise.

Mrs.Robinson sat the grocery bags down on the kitchen counter, and began putting things away.

Rob couldn't help but take a friendly stare directly at Josh's mom's breasts, having little to no concern with whether she would catch him glancing or not. By God they had ballooned in size! Just like all the other girls before the collapse of the Machine, her breasts had swelled two full cup sizes larger, making her what looked like a VERY full E.

Robby shuttered. He envisioned his lips suction cupped onto one of her gigantic udders as they hung without restriction in her shirt, latching onto it for dear life. He sighed in content.

"You alright Rob? You seem...distant." Josh asked, concerned.

"Wha-huh? Oh.... yea. I'm alright." He had to figure out what was going on.

The front door flew open once more and in walked a girl… no, a woman… a goddess…

Not the Denise he had remembered shooing away when playing video games with Josh. Not the little girl he remembered having no sexual desire towards. The puny, skinny little Denise was no more. In walked the very same Denise he had helped craft from earlier, hefting breasts just as large as her mother's, high on her chest. "Hey guys!" Denise waved.

"How's it goin' sis?" Josh politely asked, getting up.

"Not bad, not bad."

This was very strange, Rob thought. Not only were the two siblings not arguing-- which Rob was all too accustomed to seeing, but Denise didn't seem to so much as take a second glance towards him at all. Could it be possible that she doesn't have memories of the Machine at all? Were men always the shorter sex to her?

Josh stood around 5'4" inches tall which was apparently still very average for a man. However, when he got up to give his 'little' sister a hug Rob was stunned to find out Denise’s chin met with his eyes.

Rob beamed once more at Denise's breasts from afar, being pressed up against Josh's collarbone, squeezing heavily against him due to their powerful hug. Rob couldn't help but appreciate what he had helped create.

"Dinner's ready!" called Mrs.Robinson. "Get your tooshes over here before it gets cold!"

Everyone ran to the dinner table and sat down, eager to get some food into their mouth.

Dinner conversations ran scarce, as everyone was very intent on eating their food undisturbed. Denise reclined relaxingly in her chair, listening to music on her ipod while Josh focused on stuffing his face.

Rob noted Denise’s mannerisms felt off. The way she postured herself felt more confident and perhaps even more authoritative. And it seemed her relationship with her mother became more communal and less mother-daughter.

Rob then shifted his gaze over to Josh. He appeared so much more simple minded than before. He appeared innocent to the events happening around him. Rob knew this wasn't his best friend, the boy genius. The guy he knew who would so willingly dip his toes into danger if it meant creating something new and life changing.This was not the boy who created the Machine from scratch and brought him into this altered world in the first place! He pondered whether to even mention the very existence of that machine to Josh or not. It was risky. He didn't want to come off as a psycho...or cause the world to implode or something.

With a knife and fork in hand, Rob continued to contemplate the trail ahead of him.

As far as he knew it, both men and women were treated as equals in this 'version' of the world. It could only mean that the roles of both genders have not yet been significantly altered enough to snap the relationship of how women and mean live amongst each other. The average man was now 5'4 and women at 5'10, he realized....an exact swap of both heights! Rob chuckled as he reasoned, "That must be why women aren't ruling the world quite yet."

Rob gave a big sigh of relief. The last thing he wanted was to become a slave and be worked to death by the opposite sex. With all his problems settled and his mind finally at rest, Rob accepted that he could live comfortably in a world that had only simply been crafted with slightly taller, more busty women. There was no harm in that. In fact...it was better for a lust-crazed guy like himself.

Something caught Rob's attention though. He looked over at Mrs.Robinson who had been eating silently at the head of the table, with her big breasts pressed tightly up against the side. Rob watched as she made an uncomfortable expression and held her hand up to her heart. He noticed out of the corner of his eye that Denise had absentmindedly done the same. Extreme thoughts began to flood Rob’s mind. Did this world come with even more health concerns?! He must’ve harmed women by making them have much larger breasts on their frames! How could he live with himself?!

It seemed well within an instant that both women seemed to simply readjust themselves in their seats. It really didn't look like anything out of the ordinary...that is until their 'adjusting' started to assist them in creeping up higher and higher up the chair's frames.

Rob snapped his gaze over to Denise who looked completely unaware of what was going on. There she was, listening to music while sipping some soup and shuffling through her fashion magazine.

Rob was obviously extremely afraid of where this was all heading. A sense of no longer being in control set in. There was no machine and there was no easy way to stop these changes from happening! Would they stop?

The minuscule jolts of growth came in what looked like hiccups. The two women bounced slightly each time their heads rose a fraction of an inch, still completely unaware of their ever developing bodies. *Bah Bum*

It went on for what felt like was hours to Rob. He struggled to maintain a nonchalant expression, drinking in his soup slowly with an unsteady hand as the women sprouted in their seats. *Bah Bum* Several times he would end up bringing his spoon to his lips only to find its contents had all but fallen back into the bowl.

The blossoming Denise lifted her bowl high up into the air and tilted the last remaining drops into her gullet, all the while silently stretching taller as her shoulders broadened simultaneously. *Bah Bum* Rob couldn't help but take some time to admire the stress lines her breasts created in her thin T-shirt. Boy were they stressed.

*Bah Bum* Rob could hear the chairs creak as more and more weight was slowly added on. This was beginning to become too much. Rob was visibly sweating. These women were becoming too much for his small male brain to handle, and he needed to get out of the situation NOW!

Rob took a deep breath, mustering all his strength into one calm, yet assertive sentence.

"T-thank you for the meal, Mrs.Robinson." Rob's voice squeaked.

"Oh, you're very welcome Robby!" She stood up to join Rob's already standing position. Her imposing height physical weighed down his will to move. "Is your mother expecting you home so soon?"

Rob nodded profusely.

"Ok, well I'll box up some of the left overs. You tell your mother I said hello, alright?"

Rob watched as the extremely over-endowed Mrs.Robinson turned her back towards Rob and headed into the kitchen.

Then it hit him...like a rock-hard brick to the face.... What happened to his family?

Rob gave his farewells, waving goodbye to the Robinson family as he made his way back home. He was thankful he was lucky enough to have a friend who lived just a few doors down from his own home. Especially a family so welcoming as Josh's.

Evening rolled in as he stood at the foot of his front door. His body was bathed in light by the outdoor lamp while his mind brewed at what could possibly greet him at the other side of the door. He idly gazed into the doorknob, realizing how much higher up it felt than usual. Growing accustomed to his new height was not going to be an easy task.

Robby held his hand up to the doorbell, hesitating. He knew his mother and father were there, as well as his two younger sisters. They were all waiting to hear his arrival any minute. "How much could they have changed?" he wondered.

*ding-dong!*

"ROBBY!!!!!" He heard the scream of a young girl at the top floor, followed by loud, quick footsteps descending down the stairs. The door swung open.

A pair of quick tiny arms swooped around him, trapping him in a loving embrace. It was his 8 year old sister, Melanie. "I'm so glad you're home! I missed you so much!" she exclaimed, not loosening up her grip for a second.

She too had grown, Rob noticed. She now stood only 6 or so inches shorter than her bigger brother at 8 years old.. It was a shocking sight indeed.

"You OK big brother?" she asked with immense concern, reaching lovingly towards her big brother's forehead. "You don't feel too hot."

"I'm fine, Melly!" , swatting her concern away. "I'm just tired... that's all."

Witnessing his innocent little sister also become a victim to the invisible onslaught of changes throughout the world tipped the scale for Rob. Rob wanted no more of it...he needed an escape from this. Standing at the sidelines, watching development of the female human race was not an option. Regardless, these changes had been forced upon him and were no longer optional. He needed to find out what was going on....but how?

Emily, the older of the two sisters would be taller too-- as well as mom. Probably growing the same amount as Melanie had. That was all a given.

Rob began to make his way upstairs to his room, but Melanie clung onto each moment she could with her big brother.

"I was beginning to worry that you caught something terrible from Josh!" She held her index finger on her lower lip, contemplating what else to say to keep her big brother next to her for as long as possible. Rob turned towards the stairs.

"Emily had her first kiss today!"

"What!?" Rob snapped his head back towards the little girl.

"Yea, mommy says she's starting to become a real woman!" She smiled innocently up at her big brother.

"Oh. Ok. Well, uhh, I'm going to bed Melly. Don't stay up too late. I'll see you tomorrow." He didn't know what else to say.

Melly nodded her head profusely "Mhmm!"

That night Rob dreamt deeply, though his mind was anything but at ease. Images of his younger sister, Emily, standing naked before him plagued his mind. "No..." Rob tossed and turned in his bed. Her body was completely transformed! She had on a body of an adult, with large hips and a pair of long legs. Rob desperately attempted to shield his eyes but the images of her kept flooding his mind. Her small insignificant breasts lifted up slightly along with her arms as she gestured for him to come closer.

It was his sister for god's sake! He urged himself with all his might to turn the other way, but his body remained unfettered, moving forward without so much as a hiccup in its stride. She curled her index finger once more towards Rob, tugging him closer and closer.

Soon enough he found himself within a breaths distance from the adult form of his sister Emily, her long golden blonde hair cascading down her shoulders. He found her leaning in to plant a soft, delicate kiss on his lips with her own. They were warm. "I love you." she whispered. Rob twitched, and managed to pull his dream self away from his sister for just a moment.

"It's ok, we're brother and sister." She comforted, quickly closing the gap between them. She reached for his hand and placed it on her hip. "I love you big brother.", kissing him once again and resting her hand on the back of his head. Rob pulled back. "It's ok. It's ok..", she fought to keep him close.

Slowly, as Rob tried to break her embrace, he felt her strength increasing! He felt the arms wrapped around him begin to lengthen and he panicked! "Don't worry... I'm here for you." Her kissing persisted, but Rob pushed her face away with the palm of his hand, taking a few quick steps back. He felt himself open his mouth, but nothing came out.

"I'll make it better Robby. Please don't leave me..." she continued to grow. Her arms, legs, and shoulders were lengthening within his eyesight. This was so wrong! "I love you so much brother! I just want to make you happy!" she advanced towards him further, in the white empty space of the dream.

She grew and she grew, now matching Robby in height. "I'll take real good care of you Robby. You won't need to worry about a thing." Once again, she reached for his hand, but this time Robby slapped it away. "Why Robby? Why are you..." Like a whispering willow, she cried, her voice echoing off the nonexistent walls of the abyss. "Why Robby? Why!!" She grew at a much faster rate now. "WHY, ROBBY!!! WHYYYY!!!!!!" She exploded in height, breasts doubling in size! "WHY WONT YOU LOVE ME ROBBY!!!!!" She ran towards him at full speed, arms wide open in desperation!

"GAH!" Robby's eyes ripped open and he found himself in his bed, sweat falling down his forehead.

"wow...what a nightmare." he muttered to himself.

The next morning Rob was able to see Emily for the first time since the Machine had changed the world around him. It was obvious her body had changed since the event. Her straight blonde hair cascaded down her back while she sat patiently at the breakfast table waiting for her food. Upon further inspection, Rob found she had what looked like the beginning of two small breasts; something that he definitely didn't notice before.

His mom was vigorously flipping pancakes at the stove, too focused at the task at hand to notice Rob come it. She too had suffered under the hands of the Machine, growing slightly taller and more voluptuous as well.

His father sat reading the newspaper, taking bites out of his toast and drinking sips of his coffee. Rob could only assume that he too had shrunk, making him the same height as his son, standing at 5'6".

"Hey there he is now!" Robby heard a voice call out, "It took you long enough! Come have some breakfast." Rob's mother Lilly offered, placing some pancakes on a plate.

Rob drew in the rich syrupy aroma coming off of the freshly made pancakes, admiring his mother's craftsmanship.

"Thanks Mom!" He exclaimed, looking up into his mother's gorgeous green eyes.

"Not a problem, my son." She said in a sarcastic tone, followed by a silly laugh that only mom's could accomplish making.

Just then a pair of quick feet came sprinting into the kitchen. "BREAKFASSSSST!!!" Melanie hollered, jumping into the seat next to her big brother.

"Hi Rob!" She chirped up to him.

"Hi Melanie..."

She turned towards the table, which was a bit too high for her body, and attempted to perform the impossible, leaning as far forward as she could to reach the top-stacked pancake.

"Oh here ya' go honey." Mom said, moving two pancakes over to her plate. "Just say if you need more. Growing girls can have as much as they want!" she smiled down at her youngest daughter.

"Oh and Robin, don't forget we're going to Melanie's friend's birthday party today. Don't make any plans."

"Awwww what?! Come on Mom...I don't wanna go to some little girl's party." Rob whined, even in the presence of Melanie.

"It's good for you to spend some time with your family! You're not getting out of this Mr., and that's final."

Rob shlumped as far down into his chair as the tension stood still in the air. He draped his arms around the plate in front of him and let his head bob between the edge of the table and his chest, looking down at the kitchen tiles.

"It's not fair..." he muttered to himself. "Emily doesn't even have to go! Why do I have to?" he continued to complain to himself.

"Achoo!" *sniffle* "Excuse me." apologized Emily.

"Eat your pancakes, Robby. You need to have some breakfast." His mother commented.

"I don't want any," Rob retaliated, attempting to deny any and all of his mother's wishes. "--and I'm not going to that stupid party!"

With his head still down between his arms, he saw the lower half of his mother's body readjust herself in her seat.

"That's fine then Robby, but don't expect me to cater to your needs later. You hear?"

Rob just huffed some more, continuing to ignore his mother completely.

He noticed at the corner of his eye his baby sister Melly swinging her dangling legs off the chair, only...

He stared curiously, as if in a trance, confused by what he saw. It appeared that Melanie's tiny legs, as they swung back and forth, slowly began to get closer to the ground. It wasn't by much, and it could've been a trick of the eye, but Rob couldn't help but feel uneasy-- queasy even-- by the sight. He slowly peeked his eyes over his shoulder, observing her carefully.

It was true! Oh no! He concentrated on Melly's form, witnessing her frame slowly lengthening before him.

"Hmmmfphff!!!!" Rob gasped against the meat of his arm. Melanie looked over in bewilderment, as well as the rest of his family, though nothing was said.

"Oh no oh no oh no oh no!" Rob began panicking, "Not this again! How big are they going to get! My god!"

He brought his eyes back down to the floor, waiting for everyone to drift back to their meals. Anything to prevent him from further embarrassment.

Rob tilted his head towards Melanie's feet once again and found she could now comfortably rest her feet on the ground. Just then a soft delicate hand rested on the back of his head.

"You alright big brother?"

He lifted his gaze up to meet his little sister's, and what he saw showed on his face.

"You look pale." she stated in concern.

With a slack jaw, Rob wasn't doing himself much good. His little Melly had sprouted taller right before his very eyes! Her cute little button nose that he knew so well had now changed entirely, turning into a thin, feminine-shaped one. And her dainty imperfect chin was now polished to perfection, leaving no trace of what it once was. This shattered Rob's emotions. Traits that Rob looked upon as his little sister's were gone in an instant... what made her the innocent child was now gone forever.

Her jawline became more defined as his eyes watched minuscule amounts of baby fat fade away from her cheeks..

Her hand still rested on his shaken shoulder, leaning in intently for his response, eyes wide open.

"I-I'm fine Melly" , calling her by her nickname felt awkward now. "I just have a lot on my mind is all."

It wasn't enough to quench her concern, but Melanie nodded in acceptance "Ok...take care of yourself." and lifted her hand off him.

Rob sat straight in his chair, eyes void of life. There was a moments pause. Something deep inside him cried at that instant, warning him that his sibling relationship with Melanie would soon fall apart, forever being tainted by the chipped pieces that had already shattered to the ground. Disturbing thoughts arose. Thoughts of his little sister one day no longer feeling comfortable enough to speak to him crawled into his subconscious. Fighting, arguing, competition-- everything.

So he spoke.

"I love you Melanie." Rob said plainly, still absentmindedly staring towards his plate full of food.

Melanie's eyes sparkled with tears of joy when those rare words rung within her ears.

"Robby..." She gloated, leaping towards his unprepared figure. "I love you too!"

Lifting up from their clasp, Melanie asked with a hopeful expression "So does this mean you'll go to Ashley's birthday party with me?!"

With a warm smile, Rob agreed. "Sure Melanie, I'll go."

The group hopped into the family minivan, buckling up for the short trip. Melanie and Robby sat quaintly together in the back seat while Lilly, their mother, took hold of the steering wheel.

Driving to the birthday party turned out to be more than just an idle process for Rob. He found himself eyeing his mother's more prominent frame. Her breasts stood big and firm against her chest as she drove, jiggling in the slightest when making turns, quietly hinting to him that their soft texture still remained despite their increased size and mass.

Rob knew it was weird to look at his mother in that way, but he was a man, and a man has a right to admire the female form-- regardless of who it belonged to! And with that reassurance, Rob took it as all the more reason to continue leering!

It wasn't just her motherly tits that had swelled, but other parts of her frame had become more defined as well. Her baby-carrying hips had grown, widening further as they portrayed her gender in the most sultry way possible. He could tell by how they stuck out more in the car seat. Boy was it a sight to see.

Immediately as the thought crossed his mind, Rob felt himself getting too carried away with his daydreaming once again, feeling his member begin to harden inside his pants.

It seemed like some devious plan from the heavens because at that very exact moment, Lilly looked into her rear-view mirror to check up on the two of them. Rob swatted his hands towards his crotch at the sight of his mother's eyes through the mirror, attempting to cover his burgeoning bulge.

Lack of a good memory, Rob neglected to remember his sister sitting right next to him. Melanie was blinking at him with her big blue eyes, confused. First she looked at his face, then down at his hands, and then back up, wondering what the hell was going on.

She wanted to speak, but she held her voice of back, sighing in the process. It was best left unspoken.

Rob saw no part in her withdrawal and continued to try to play it all off as one big misunderstanding to everyone around him, readjusting his legs and his seating position.

"What?" Rob snapped, throwing his hands up in the air at his sister.

"We're almost there! About 5 more minutes!" Rob's mom announced.

"Yay!!!" Melanie cheered, wrapping her arm around her brother.

"yay..." Rob echoed unenthusiastically. He still couldn't believe he agreed to go to this thing.

Rob peered out the car window just as they reached their destination. There laid a house that one could almost classify as a mansion, yet not quite so luxurious. It was however immense, with large trees surrounding the property, providing shade even on the hottest of days.

"We're here we're here we're here!" Melanie exclaimed, fidgeting wildly in her seat as her mother parked the car.

The long cobblestone pathway presented Rob with a movie-like sensation. Each stone was placed ever so meticulously, as a way to welcome the many guests that would be walking on it this morning. The splashing sounds of giggling young girls escaped from the lofty Spanish-style house, letting the Robinson family know what lie ahead of them. Melanie's smile grew only wider.

An archway through the center of the house embraced the newcomers as it guided them towards the backyard.

Lilly caught sight of the other mothers mingling about as Melly saw her friends splashing about in the Olympic sized pool. The hostess, obviously the mother of the birthday girl came up to greet them.

"Why hello there!" She greeted Lilly politely, shaking her hand in the process. "You must be Melanie's mother. You've grown such a fine young woman, you know that?"

"Why thank you," Lilly spread a white smile towards her new friend, "Ashley's quite the well-mannered lady herself."

Rob and Melly peered out across the vast backyard only to quickly be interrupted by Ashley's mother.

"Why don't you two go put on your swim suits! The bathroom is up the stairs to your left!" Her voice faked excitement and energy.

Without so much as a response, both of the Robinson's kids ran inside the house.

"I had no idea Ashley was so...rich." Rob blatantly said, standing in the huge marble bathroom.

Melly payed no mind to her big brother's comment, and proceeded to take her clothes off.

"M-mell, what are you doing?!"

Melanie stopped dead in her tracks. "What? I'm changing to go swimming. We're family, there's nothing to be ashamed of." , continuing on with taking her shirt completely off.

Rob stood mute, staring at his sister's naked torso. It was so wrong, but he couldn't help but feel curious about the female body. Her pert breasts stuck right out in front of her chest and reminded Robby of the few times he had seen her training bras in the laundry. At the time they could only barely fill those, but now thanks to her recent growth spurt it appeared as though she could almost out fill an A-cup. Rob's gaze shifted downwards as she began to slip her jeans off, revealing her bare privates. It was the first time Rob had seen anything like it. He stared.

Melanie payed no mind to it, casually slipping her bikini on.

"You gonna change too?" She finally inquired, realizing he still hadn't stopped staring.

Rob flinched at the realization and instinctively started to take his clothes off.

He positioned himself very carefully, hunching forward as he stripped naked in front of Melanie. The last thing he wanted to do was have his sister see his rod, but it proved to be nearly impossible when in such close proximity with her. Rob quickly slipped his jeans off only to already catch Melanie staring directly at his crotch. Her expression is what got him. She appeared extremely fascinated, being the first time she had ever seen a penis before. She stared and stared, admiring his length as Rob fumbled to get his swimming trunks on. How embarrassing!

Melanie smiled once she found Rob staring back at her. Unlike her brother, she couldn't care less if she was caught staring or not, and proceeding to walk out of the bathroom.

Rob desperately tried to have a word with Melanie about what had just happened, but it was too late, she had already frolicked off. He found himself at the pool before he knew it, watching Melanie dive right into the pool after her friends. Rob took it as a hint to relax and take his mind off things. A particular lounge chair caught his attention.

After applying some sunblock onto his chest and shoulders, he found his eyelids quickly growing heavy as his muscles relaxed for the first time in two days. His mind wandered, traveling from one point to another, only to return to the same image of his sister standing naked before him like he had seen just moments ago. It was clear, as if he was still gazing at her idle form in the bathroom. His unconscious, sleeping mind took hold of what he saw, bringing forth his most primal instincts-- regardless of its target.

First, he dreamt that she started stretching in all kinds of outrageous ways, spreading her long legs as far apart as possible. Her arms were next, being tucked behind her back as a means to thrust her tiny breasts as far towards her big brother as she could. He felt his face flush from the embarrassment and shock, but his dreaming mind continued the painful barrage nonetheless.

She began talking dirty to him, though now she was no longer his sister, but a very sexy classmate he admired who looked strikingly similar to his baby sister-- almost identical.

"Mmmm...." moans escaped from the girl's subtle lips. "Ohhh...Uhhhhhhhhhh!!" her voice echoed in his ears so strikingly similar to that of his sister's. Waves of pleasure coursed through his veins with each passing heartbeat as the sun shone down upon his physical form, outside the dream world.

"Oh god.....Robby." her lips muttered. "…..Robby..." He felt his trunks lift at the crotch.

Finally, he imagined what he dreaded most: his little sister—or this woman—was growing...maturing....becoming all the more womanly. At first he only added two inches to her frame, but soon he found himself lengthening her shoulders and swelling her breasts to what looked like two average sized grapefruits. "There we go", his sun-baked face grinned mischievously.

Just then he sensed the light on his face vanish. He opened his eyes to greet a close-up of Melanie's face.

"Do you mind?" she held up a bottle of suntan lotion.

"No no, of course not." Rob responded automatically, leaning up from his delightful nap.

It was when she twirled her body away from him that Rob noticed she had changed yet again, and it wasn't just coincidence! She had morphed into exactly how Rob envisioned her! Rob took a deep breath, realizing exactly what he'd just done unconsciously. He surveyed her body, trying to scrape up some sense of shame and guilt for what he had done, but the allure of the opposite sex was still there. His sister had changed yet again, and in his unconscious mind...for the better. In his conscious mind...for the better.

She sat down at the tail-end of the lounge chair, moving her long hair away from her back. "Do my back first please." She politely asked, pulling at the string of her bikini top. She used both hands to cup her modest breasts inside her bikini top whilst Rob had her full bare back to work on.

Rob squirted some lotion onto his hands and hesitantly began to massage into her warm shoulders and arms. "Mmmmm....that feels SO good."

The soft, squishy sensation of her meat as he lathered her arms sent shivers up Rob's spine. It was like nothing he had felt before. Never in his life had he felt something so soft and sensuous. His mind slowly began to drift unconsciously back to the vision of his baby sister.

There she was, both in his mind and in front of him, growing, he imagined. It was as if he had control of the situation, because within moments he felt his hands slowly slip further down her back, but he did not move his hands.

"Ooohh..." She cooed, as Robby's hands expertly spread the slippery substance all throughout her lower back and waist.

He increased her height more as he closed his eyes, finally making her the same height as Rob. He felt his fingers slip with the lotion slightly apart as her torso grew wider beneath his touch.

"Now my stomach." she insisted, completely unaware of her transformation.. Rob silently obeyed, moving his hands around her after adding more lotion.

This time he added four more inches to her frame. Instantly, he felt an explosion of female flesh hit him as her body surged larger and larger against him now, pushing one of his legs completely off the lounge chair. She unconsciously cleared her throat, "Hnnhnnn!" It made Rob flinch out of fear, but only to quickly remember her lack of awareness to the situation at hand.

Rob knew she couldn't sense him changing her, but still he felt the need to be silent.

Yet still, he continued. And with the rhythm of the motions of his hands on her stomach, he envisioned her breasts swelling larger. At first only a cup in size, but then a few more. Immediately he felt her posture alter as the added weight caused her posture to suddenly slouch lower. The back of Rob's hands grazed the very undersides of her new swells as they became harder and harder to ignore.

Rob found himself compelled to slowly move his hands closer and closer to the goal in mind, only stopping to gauge her emotions as he tested the water. Just then a mischievous plan came to mind.

Rob made her grow another cup size larger, causing the increased weight of her breasts to slightly teardrop more, covering his fingers in the process. Rob couldn't help it, extreme jolts of pleasure shot through his veins at that very moment, hardening his cock in his pants all the more. His neck was on fire... and Melanie could sense it.

Now with a sense of uneasiness filling the air, Rob took extra care with each step he took. Slowly, with the mindset of a child not wanting to wake up his parents, he continued to gyrate his hands over her ribcage all the while her womanly flesh pressed against his knuckles. Nothing could beat that moment, except for when Melanie reached over to pull one of Rob's legs on the other side of her, allowing room for her to scoot even closer to his stone-skin crotch. He somehow managed to harden further.

At that moment his sense of reality had dwindle to nothing, his mind being plagued with wave after wave of sexual encounters that he could(literally) only dream of. His mind ran rampant.

So he continued his sex-crazed assault on Melanie's body, making adjustments to her ever-improving form. First he imagined tiny freckles sprinkling over her cheeks and nose. Then he envisioned her eyes. They were no longer the big baby blue eyes he could picture so clearly, they were green now and sparkling like emeralds. They felt oh so warm and welcoming, and only helped to accentuate her developing goddess of a body.

He opened his eyes and met them in person for the first time. They burned on a very humble note, scarring his soul as he stared deeply into his sister's eyes. It was then that he realized...he was creating...someone else!

But that did not stop him. He continued, altering her hair to what one could only describe as the most vibrant colors of a maple tree. Strands of her hair shone bright red and orange on the pool's reflections. Without saying it, this only strengthened the allure her eyes presented to the new her.

"I think you've massaged there enough! You're beginning to give me a rash." She giggled, "Why don't you try up here?" She grabbed Rob by the hands and placed them over the softest material known to man: her boobs, her breasts, her ta-tas!

The sound of a girl in sandals walked in to interrupt Rob in the most ecstatic moment in his life. Nooo!!!

"Melanie, what on Earth are you doing!?" The unknown voice called out. His goliath of a sister was blocking everything in front of him.

"Oh nothing, Rob's just helping me put on some suntan lotion. Isn't that right hun?" She turned, staring directly into his gaze with her emeralds.

Rob cowered away, quickly overcome by the beauty of what he had just created, and stuck his face against his big sister's back.

"Awww...he's so shy isn't he?" The unknown girl spoke.

"Yea, he can get that way."

Rob felt his arms wrap tightly around his sister as he kept his eyes shut. A sense of safety overcame him...and it turned him on beyond belief. Her warm skin felt good against his cheek. In response his trunks began to push up against his sister's lower back. Soon his entire length lay resting against her and there was nothing he could do about it! So he clung onto her for deal life...helpless.

Wave after wave of pleasure hit him as he began to rub against her quietly. He couldn't help it, it was too much. He just couldn't help but envision her body growing again-- but no! Rob tried with all his might to focus on other things! Anything... but.... her!!! It was impossible. He visualized her body growing right in front of him!

Quickly he felt the sister he wrapped ever so tightly around begin to push his embrace away. He opened his eyes and saw as she began to take up more and more of the lounge chair, leaving very little room for him!

The two girls continued to mingle, unfazed as the growth continued.

It didn't take long for Rob to realize that Melanie was no longer wearing anything to cover her great big breast! He could only make out their presence from behind her by taking small glances under he arm.

"Shhh shhh, it's ok Robby." he heard his sister comfort him.

Rob readjusted himself with legs spread painfully apart and latched passionately against his sister. This proved to be a meaningless task as he was the cause of this colossus girl to become so large, yet he still attempted to find shelter against her for all that he was worth. This was all too much! He tightened his grip, quickly realizing one of his hands had landed directly onto one of her tits! But instead of a negative reaction, Rob found her looking down at him... almost maternally.

"Why don't you come say hello, Robby?" She turned her huge body towards him and grabbed onto his little waist, hoisting him up in the air and onto her lap. The other girl laughed as Robby's eyes first settled on her. He gasped it shock as he realized the girl standing in before him was none other than Katie, one of Denise's friends!

She too had nothing covering her huge breasts from plain sight as they hung ever so perfectly off her youthful body. And her tanned skin echoed sexuality, which only ripened those wonderful melons of hers. He couldn't help but lick his lips at the sight of her plump, lively nipples.

Upon further inspection, the finest of golden hairs could be seen scattered across her chest, no longer than an eighth of an inch in height, but shining from her freshly dried skin nonetheless. In a strange ambient way, they seemed to accentuate the beauty her young skin had on her big bosom.

"How's it going Robster?" She chirped, throwing Rob out of his daydream while leaning forward to ruffle his hair. Rob could only eye her tits as they lifted off her chest to hang ever so enticingly next to his face.

Rob simply nodded in response. His voice was long but gone after rendering his 'baby' sister into a tall sex goddess. It was al SO SO wrong.

He watched as her attention quickly left him and focused back up to Melanie.

"So how long have you two been going out?"

…

…

…...................

Melanie was casually resting her hands on Rob's shoulders as she spoke, "Oh I dunno...about 7 months now? Right Robby?" She leaned over him to meet with his eyes.

"I-I-I"

Both the girls laughed as he fumbled over his own words.

Melanie continued, "Yea, I would say about 7 months. Ever since I turned 18, remember?" She smiled in response to Katie, who was now sitting Indian-style on the lounge chair next to them.

Robby's mind was not focused on the conversation at hand however, but on the pillows he had been so lucky enough to use as a headrest. He could only admire his own craftsmanship. Growing his sister's breasts to such a size was not something he could let go unappreciated for. In fact, they had out grown the largest breasts in Denise's clique: Katie's!

His eyes locked onto Katie's perfect orbs once again as the two girls continued to mingle unknowingly. Rob felt his mind slip, but this time he didn't struggle against it. He let the weight of his eyelids pull him deeper into his subconscious as his mind attempted to alter the girl in front of him. First, he thought. "her breasts..."

bigger...Bigger...BIGGER!!

Her shiny young breasts glowed in the sunlight as they swelled slowly in the middle of the conversation. Her arms lay akimbo in her lap as her breasts began to cover more and more of the view in between, swelling bigger and bigger...

"So I told Daniel to go get it herself and she was like, nuh uh!" Katie's body shook from the gesture, sending erotic jiggles and jostles of all kinds all around her beautiful bust. It felt like Rob managed to just go flaccid when his dick grew rock hard once again. Damn her...

"No way! Did you tell her off?!" Melanie gasped in shock, obviously immersed in the conversation.

Rob grew a wide smile as he peeked over Melanie's side-- since her shoulders were too high to look over now-- and took a mental note of Katie's figure. He rested his head against his ex-sister's warm back and closed his eyes, picturing the beautiful blonde on the lounge chair. He felt his penis twitch from the vision. This girl was absolutely stunning!

Ever the slightest bit taller, he imagined, inching her up.

He peeked over at her again just as the changes took effect! His penis throbbed forward in his swim trunks, pushing the material against Melanie's lower back.

A little more, he reasoned, watching as her form elongated in his mind slightly. He manhood stood painfully rock hard now, poking Melanie in the back. Rob truly hoped she couldn't feel it.

Once more he stole a quick peek at Katie as she moved her arms around, talking. She grew.

Rob watched as her height finally appeared to match that of Melanie's and that sent Rob off the deep end. Hi swim trunk's meshing gave the slightest sensation that something was cupping his jewels. He exploded inside his swim trunks violently as his penis involuntarily flexed over and over again from the reverberating images in his mind. These two well endowed teens were just too much!

The girls got up and began to gather their things, sliding Robby down onto his feet in the process well before he was ready.

"You alright there, Robby?" Melanie took a hold of him by the shoulders, trying to straighten him.

"I think the poor guy got a little too much sun." He heard Katie inquire just as his vision completely blacked out.

Rob dreamt he was in a white room-- a room without walls. Though he had been in this room before, it still left him uneasy. He recalled his last visit here with his sister Emily, growing ever larger in front of him. He saw his dream self shutter from the flashback.

A small girl appeared next to him. It was Melanie, fully clothed in her old school uniform.

"I know what you did Rob. I know what you did to me..." her voice was very monotone. She continued, "You changed me. Why Robby? Was I not good enough for you?" She cradled his big hand between her small ones.

"I became exactly what you wanted only because I accepted you with open arms," This didn't make sense to Rob. He wanted to ask her many questions but she had more to say. "and I will continue to accept whatever it is you're doing to me with open arms as long as you request it from me Robby....." There was a long pause as they let themselves feel the presence of one another, holding hands. "Anything to make you feel good...."

"...Whatever it takes." She finished, proving her loyalty and trust to her big brother. *slurp*

"W-Why are you doing this?" Rob managed to say.

"Because you need me, and as long as you need me I'll be there for you. You need someone to cuddle up against and you got exactly that. If you let me, I can be so much more for you." *slurp slurp*

A very sly expression swept across her face and Rob didn't let that go unnoticed.

Rob was open to her, "Do you want this to happen?"

There was a pause-- a pause all too similar to that he remembered from Denise. THAT was what he saw within his sister....Denise.

"I want what you want, big brother." She replied simply, as if that was enough.

Rob began, "But-- *slurp slurp*

"But don't you care that I changed you..." *slurp* "...without your permission?" Rob felt his dick begin to harden randomly.

An image of great big breasts popped into his mind and he found it difficult to focus on what his little sister was saying behind them.

"I-- *slurp* – when we-- *slurp slurp* --it doesn't matter--*slurp*--love you." The breasts jiggled tantalizingly in his face and he grew harder.

"You ther-- *slurp slurp slurp slurp slurp* big brother?" *lap lap slurp lap LAP SLURP SLURP LAP*

Rob broke out of his dream, throwing his sheets off of him in the process. There knelt between his legs was Katie, with her bright blonde head of hair, bobbing up and down between his legs, sucking him off for all he was worth.

*SLLLLLlllllllllllllluuuuuuurrrrrrpppppppp!!!*

Rob felt his legs stiffen from the earth-shattering suction this girl had.

With a *Pop!* Katie lifted her gaze up at him. "Oh good, you're up. I hope you don't mind. I kind of helped myself." and she went back to work after making a big pearly-white grin at him.

His manhood was already screaming for release, already red and slowly turning purple. Who knew how long he'd been getting this blowjob for.

He watched as her head went up and down and up and down, her hands resting on each of his thighs.

Rob let out a soft moan, signaling Katie that she was nearing her goal. In response she turned it into overdrive, popping his cock out from between her lush lips and began whacking him off at lightning speed.

"OOOooooHHHH GODDDD!!!!!!" Rob clenched onto the mattress for all he was worth.

Katie's eyes lit up as she saw the head of his cock begin to swell extremely fast. She quickly wrapped her lips back onto the head and began licking wildly!

"OHOHhhhhhhhhhhhhhhhhhhhhhhh.................FFFFFFFUUUUUUUUUUUUUUUUU--

Load after load after load of cum squirted into Katie's mouth. She fought to keep it all in her mouth, accepting that she needed to swallow it as it came.

It only heightened Rob's ecstasy to see this pretty girl swallow everything he gave her.

Soon after his spasms stopped, she looked up at him and licked her lips. "Yummy."

She rolled on over next to him and placed her head on Rob's pillow, still stark naked.

"I hope you didn't mind." She turned towards him, "but I just had to take care of that pesky little morning wood.", squeezing his flaccid member in the process.

Half his body was covered by this woman as she cuddled up against him. Lucky for her, Rob was too busy still enjoying the waves of pleasure echoing through him. With a casual yawn, Katie draped her one big leg on top Rob's lower half of his body.

"Mmmm....you like that?" she purred, feeling his dick pulse against her thigh.

Rob couldn't help but nod. This experience pulsing through his veins was too good of a feeling to end now!

"I...love it." He mumbled, groping at the plumpness of her thigh. "You're so sexy."

Oops! A little too much there, Rob thought.

She giggled, "Why thank you!"

As time continued on by, Rob began to feel more and more comfortable with her presence than ever before. He loved feeling her weight against half his body as he laid next to her. He took the opportunity to admire the female form, feeling all over her body.

Something caught him as off though-- out of place. He had his hand resting on her breast, squishing and moving it for all it was worth, but he kept getting thrown out of his testosterone driven ecstasy. It was getting harder to breathe! Rob tried to shift her away but he couldn't! He felt himself harden once he recognized what was happening, despite just unleashing his load. She was getting heavier on top of him!

Her body was soon becoming too much for Rob to handle, but before he could speak it seemed Katie caught a hold of the situation.

"W-What's going on!?" Katie said, unsure of herself.

Rob's eye flew wide open, surprised she even knew she was changing!

Rob fought to break out from underneath her, "K-katie.......you're squishing me!"

"Oh my goodness, sorry!" She yelped, jumping over to the other side of the bed.

"Hold me Robby, I'm so scared!" She reached over and snatched him like a professional thief, spooning him against her swelling body. Between her breasts he could feel her heartbeat. *Tha-thump... tha-thump... tha-tump...* With each pulse her body pushed out against him by the tiniest bit, slowly covering Rob's vision. He could feel every inch of her body... growing. She had to be nearing 6 feet tall!

"It's not stopping!" She panicked, mashing her boobs even tighter against his tiny head. *thump!... thump!... thump! thump!* She grew faster now, truly panicking and causing her heart rate to go up!

"Robby make it stop make it stop!" *THUMP!!! THUMP!!! THUMP!!!!* He felt his head become completely engulfed by her milk tanks, more and more, as her limbs increased in length! Her skin glowed from the slight sweat spreading across her body.

*THUMP THUMP Thump thump...thump.....thump.....thump...* Her heartbeat slowly came back to normal. Her growing had finally ceased.

"R-Robby...I-I-I..."

For the first time, it was not Rob who had been rendered speechless. Some way, some how, she had become conscious of her growing....which was not good.

"I grew so fast Robby...I didn't know what to do!" She sat up in bed, wailing into her hands, tears tumbling down her beautiful cheeks.

"*sniffle* I'm so glad I had you here with me.*sniff*" She reached out and petted Rob's hair. "I don't know what I would've done without you..." Her eyes were a touch red from wiping them so much.

Rob took a moment before joining by her side, "It's no problem, Katie,", he began, before taking note of how much larger her frame was in comparison to him now. With her slouched forward, he eyes were only level with her shoulders! She was even taller than he imagine! Maybe closer to 6'1".

"That sure was scary though, " he continued, "I don't know what I would've done if I started growing."

She sniffled, "W-well, I guess I could've used a couple more inches." she admitted to herself, though Rob couldn't have agreed more! She was huge!

"I've always wanted to be taller than Melanie and now I can be." Her tears stopped and she peered down at her boobs. "And I think these puppies might've gotten a little bigger as well!" her demeanor had now completely flipped. "Don't you think?" She laughed, recalling just smothering him to a pulp.

"I uhhh....."

She continued to giggle wholeheartedly, "I know you liked it!"

Her face quickly fell into a sly expression, pausing in thought."

"Did you like...feeling me...grow, Robby?" Her voice was more sultry than curious.

She continued, "Did you enjoy how I pressed you up against my big...BIG breasts?" She hefted her tits up, as if presenting them on a dinner plate.

"K-k-katie..."

"You did, didn't you? You liked how I smothered you up against my breasts. Like a baby. Like a little baby with his mommy....hmm?"

"Katie, I-"

"Shh...shh...It's ok...." She held her index finger against his lips. "I just want to know why I started growing." However, she grinned knowingly as she wrapped her fingers around his cock..

"It couldn't have been this....could it?" She asked playfully, tugging at it. Rob let out a moan.

"Nnnnn, Katie...I...I don't know what happened!" Rob was being honest! He had no idea what had caused that random growth spurt all of a sudden.

"I have a feeling someone's lying!" She chirped, rubbing him up and down now.

"K-K-kayyytteeeeee....plleeeeassssseee, I'm not lyyyyinnnnnng."

She shook her index finger in the air at him, "uh uh Uhhhh. I don't like how you're lying right to my face, Robby." She pushed him down onto the pillows.

"Someone needs to be punished!" She began pumping him furiously. And sure enough, his soft cock was beginning to come to life once again!

Her voice was quivering from the vigorousness she put forth into jacking Rob off. "Loo~~kkk~~aatt~~theese~~big ass~ss~ titties~~~R~Robby!" She began, "Thess~se big ff~fuckin' ~tittt~ts!!"

It took no time at all for Rob to feel his orgasm approaching. He saw Katie reach for a dixie cup.

"T~~this ~~way we'll know f~fo~r ~~sure~!"

Rob erupted harder than ever right into the small dixie cup, only filling about a quarter of it, but it was enough to produce a cracked smile upon Katie's face.

"Bottoms up!" She said, tilting her gaze looking down at him while her head tilted up to bring in the sweet liquid. What a sight it was.

He watched as her throat flexed, swallowing every last bit of it down.

Rob caught sight of Katie's hand playing with one of her boobs, casually feeling its weight as she savored his gift.

She wiped her lips off with the back of her arm and chirped "The deed is done!", childishly waiting for her suspicions to hit her like a speeding bullet.

She stared deeply into Rob's eyes as he lay flat on the bed. Her hands on both sides of his head propped her body above his, as she loomed above him, waiting for something to happen. A giddy "HmmmMMmmMmmmmmHmmmmm..." was escaping her intoxicated stare. She looked as if she was drunk with power.

"I think I'll just lay down...riiiiiiiight heeeeerree..." She said, falling face down onto Rob and engulfing his smaller frame in the process. A person walking into the room would not notice Rob's existence.

She flipped onto her back, bringing Rob with her. "There we go! You just straddle yourself in and enjoy the ride, alright cutie!?" She grinned up at him as Rob found himself doing exactly that, a leg on each side of her hips.

As if sensing it coming, her body began to grow larger underneath him. "Better grab ahold of something, you're in for a bumpy ride!" She giggled, gesturing towards her huge rack. "These'll do!" Rob didn't need to be told twice, he grabbed onto those massive melons faster than he thought possible.

Katie started bumping up and down and moving and jiggling in every direction while she grew, as if in the middle of a seizure. Rob looked down at her at first but soon found himself struggling to stay on top of her, regardless of the 'handles' he gripped onto!

Like on a horse, he fought to stay on her as she continued to vigorously flail around, pulsing larger with each heartbeat! She kept her arms at her side, but it didn't make the task of staying 'saddled-in' any easier! Rob felt her extra womanly meat flap against him. Her thighs, her abdomen-- everything! And to top it all off, this riding horse was growing!

"I knew it!" She exclaimed, "Your jizz is like magic, Robby!"

As the rumbling and shaking came to a stop, Rob noticed she seemed a bit too overjoyed at discovering his semen could make her grow. Though on another note, why was his cum making her bigger anyway!? Could it be from the effects of the machine? Rob pondered.

"Oh my god, this is so great, Robby! I can't wait to get taller!"

...That didn't sound good.

"Now with your help I can become exactly how I've dreamt!" She was on all fours now, looming above him.

She waited for his response.

"I-I dunno Katie, you're already pretty big as it is." Rob managed to break a smile, though unconvincing. Luckily enough, she ignored him entirely.

"Promise me you won't tell the girls! I don't want them to find out!" She kissed Rob passionately on the lips, sealing the deal. "Promise?"

O-other girls? What did she mean by that! There's more of these behemoths?! Even MORE questions...

Rob nodded.

"Ok good. I'll need you to fill this up for me then." She threw a dixie cup in his lap him, "Just let me know when you're done!"

With that she got up, completely naked, and walked out the bedroom door-- all 6 foot, 2 inches of her.

Rob fapped away the rest of the night and into the evening of the next day, not getting an ounce of sleep. His mind was plagued by the fresh images of Katie's humongous frame, looming over him as her fresh big breasts hung right over his face. Her nipples mere inches away from his eager lips.

He looked over to his side and realized the dixie cup had been filled to the brim. Boy, what a sight, he thought. To think that he managed to squeeze all that out overnight was astonishing. It almost appeared like he was producing more semen than he was used to.

Just then Katie came walking into the bedroom, formally clothed and applying an earring with both hands.

"Ahh I see you've done a good job there! Thank you soooo much Robby!" She walked up to him and took the cup away, only to come back moments later with a purse in hand and Melanie by her side.

"Now hurry up and get dressed. We've got a dinner date with Denise!" Katie informed Rob. The top of Melanie's head seemed to only reach the bridge of Katie's nose.

"Come on honey, put some clothes on." Melanie pulled the sheets off of him, revealing many cum stains all around him. Rob blushed deep red.

"Aw don't worry about it babe. I know when I'm not around to help you it can get awfully difficult to hold it in." She grinned down at him.

*Ding dong*

The trio waited patiently at the front steps of the Robinson's mid-sized suburban house. The front porch light spotlighted them as the sound of footsteps came dashing up to the other side of the door.

The door cracked open and out popped Josh's little head. He may have been several inches taller than Rob but it still provided him little leverage in comparison to the two colossal women before him.

"Rob, Katie, Melanie! How are you guys!?" Rob was taken aback by his unfettered personality towards the girls. There was no other explanation, he must have grown accustomed to women at this size.

"Oh would you look at you!", Melanie chirped, lifting him up off the ground and into a breathtaking breast-filled hug. "You've grown since I've last seen you!" She held him out in front of her, examining his figure.

Josh laughed with confidence, "Haha! No, I think it's you who's been doing all the growing!" Melanie playfully measured the top of her head with one hand and moved it horizontally over Josh's head. "Yea, you may be right!" She cracked a big smile as they both laughed simultaneously.

Just then a big figure appeared behind Josh. It was Denise...and it only strengthened Rob's reasoning as to why Josh took the other girl's height so easily. She was easily a head taller than him!

"I was wondering what all that ruckus was about! Hey girls!" Denise held out her hands, scooching past her brother and embracing the two young ladies as a whole. Rob got caught in between them, obviously unimportant, though it didn't bother him. He was too busy enjoying the feminine aroma coming from the three girls, mixed with the faint scent of hamburgers, which Rob assumed was for dinner.

After breaking her embrace, Denise stood back up to her full height. "I hope you're all hungry, I just finished the french fries! Please, come on in and have a seat!" She backed up, shifting her sibling unintentionally away as she opened the door all the way for her guests.

Dinner brought a very warm feeling to the guests. Katie sat at one end of the table while Denise scooted her chair in from the other. Rob and Melanie were on one side of the table while Josh sat by himself on the other, hovering nearby Denise.

"Go right on ahead and dig in. Don't worry about manners." Denise said

A lush valley of food sat upon the tabletop. Chicken, gravy, mac 'n cheese, mashed potatoes...it really seemed like a lot of food, but the girls savagely grabbed at some drum sticks and piled up different assortments of food onto their plates.

Josh was right on in there with them, though getting ahold of a much smaller portion than the surrounding women. Rob's mouth gaped in awe, stunned by the amount of food the girls were stuffing down their throats. It seemed like an awful lot.

Meanwhile, Melanie had prepared a plate for him, setting it in front of him.

"Thank you, Melly." He said instinctively, before immediately realizing once again that she was no longer the little sister he remembered so fondly. Instead his girlfriend sat beside him in this alternate world.

Melanie's head perked up at the comment. "That's a cute little nickname. Did you just come up with it, Robby?" He nodded his head before look back down at his food.

At the corner of his eye he saw Katie push her chair out. "I just forgot something! I'll be right back-- if you'll excuse me."

Her large form stood up and walked into the kitchen, but not before grabbing her purse that hung off the chair ever so innocently. Rob knew exactly what she had planned...

Both Melanie and Denise went about mingling, nibbling at their giant plate of food while Josh and Rob sat silently, casually listening in on the conversation. Only a few minutes went by before Katie came walking back into the dining room with a glass of milk in hand.

Rob watched the glass like a hawk, knowing exactly what the contents of the milk contained. He needed to somehow stop her from drinking it...but it was too late. Before he knew it she rested the glass against her lips, tipping it up ever so slightly as to allow the silky white liquid to fall into her mouth. Melanie caught sight of the milk and her gaze seemed to linger a moment too long on it before turning back to Denise. Rob noticed the occurrence and made a mental note on it. Odd.

"Yea, white roses in your garden may seem wonderful and all but the traditional reds always seem to stand out more for me. Don't you agree?" Denise continued to exchange simple conversations with Melanie, though Melanie seemed a lot more distant than a few moments prior, watching Katie every time the glass of milk lifted off the table. It almost seemed like she knew...

Rob felt a hand get placed on his right thigh. It was Melanie. He looked up at her and saw her smile down playfully at him. Something was definitely odd about her though. It almost appeared as if Melanie was getting antsy about waiting for Katie to change.

She began to methodically rub her hand up and down Rob's thigh, as if in thought. Slowly beneath the tablecloth she began to work her way closer to his crotch, all the while she kept her conversation with Denise.

Rob felt his loins stir, baffled by how Melanie could do such a thing to him during dinner! He tried to shift her hand away, but she flexed her arm muscles stiffly as if in a way to suggest she would not be deterred from her overall goal in mind. Slowly her hand glided closer and closer.

Of to the side, Katie continued to gulp down the large glass of cold semen-enriched milk. Rob knew she was only moments away from stretching fractions of an inch taller. Better yet, for all he knew she was already bigger than five minutes ago!

"Red roses would go great with my yellow tulips, don't you think?" Denise continued babbling, completely unaware that Melanie had no interest whatsoever in the debate of her garden. "I could plant them against one another. The vibrant red and yellow would really stand out." Rob watched Melanie nod from below while her hand rubbed his crotch in one circular motion after another.

"Uh huh...mmmhmmm." Melanie casually agreed, urging Denise to proceed.

Rob could feel his rod stiffen upwards now, making Melanie's circular motions obtuse. She grabbed ahold of his hardened cock through the material of Rob's jeans and began to squeeze it every few seconds. Jolts of pleasure shot through Rob as he tried with all his might to keep a casual composure from the waist up. He shot stern glances at Melanie, attempting to hint to her that he had enough, but to no avail. She just grinned down at him with a crooked smile, knowingly.

Katie began to shift in her seat, catching the attention of both Melanie and Rob. It may have been the way she had readjusted her body, but she seemed to fill her top a lot more. Rob knew it wasn't a coincidence, she had definitely grown taller! Her skin glowed with power...and it was obvious.

Only a fourth of the glass remained in front of Katie, and with a glossy expression Katie reached down a finished its contents, wiping her lips off with her forearm. "Ahh...." She said, leaning back in satisfaction.

The action seemed to have had an impact on Melanie as she continued to work at Rob's cock with all the more vigor underneath the tablecloth.

Through the extremely enhanced exterior of his little sister, Rob could see a hint of what appeared to be jealousy seeping out of her body language. Her gaze was fixed and determined as she tugged and pulled at Rob's cock. Could she possibly be aware of what his semen was capable of?

Just then she began to unzip his pants, slowly, as to not make a sound. Rob quickly reacted by snatching her arm, along with a stern look at her eyes as way to hint "Don't.". She was obviously unfazed by his less than convincing grip, and continued on with her work. All the while she offhandedly carried on with her meal, feeding herself spoonfuls of mashed potatoes with her other hand as if nothing was out of the ordinary. It shocked Rob to see how skillful she was at hiding her actions.

Now with Melanie's open access to Rob's bare cock, Rob was finding it increasingly difficult to keep a straight face-- let alone a relaxed posture!

Denise began to take note of the slight bickering and commotion coming from underneath the table, and her curiosity was only heightened when she did in fact hear the *ziiip!* noise.

She casually let her fork fall to the floor.

"Oops! Clumsy me!" She exclaimed, innocently.

What she caught sight of was nothing short of jaw dropping. There in front of her, Denise saw it all: Melanie's large hand wrapped around Rob's throbbing cock, beating him off rhythmically. Denise jerked her head up in response to the sight, only to slam her against the underside of the table.

*BANG!*

"Owww oh oh oh!!" Denise rubbed her head, only partially taking notice that the fapping sound underneath the table had stopped.

"Oh my god, Denise, are you all right?" Melanie asked with mock concern. She was obviously more concerned with whether she had been caught in the act than of Denise's well being. Nevertheless, she stood up to begin walking towards her injured friend, only to find that her hand was covered in Rob's cum! Though luckily for her, Denise signaled to Melanie that she was alright and was able to quickly sit down.

Melanie shot a quick look over to Rob and found him limp, in ecstasy from the climax. He lay slouched on his chair waiting for his crotch to stop convulsing. Melanie grabbed a nearby napkin to clean herself off but found to her amazement that she was already clean! Obviously confused, she looked down at the carpet to see if it had slipped off, but still...nothing. Not thinking much else of it, she continued on with her dinner. All the while allowing Rob to recuperate.
