“Ahh!” Luna moaned in ecstasy as her brother filled her up completely. His body trembled against hers, giving her waves of pleasure.

“Oh, Levi,” she sighed blissfully as he writhed and thrashed around within her, each movement sending a new ripple of sensation through her body. “You feel so perfect,” she murmured contentedly as the tiny fleshy toy caused ripples of joy to course through her veins.

She could remember the first time she used a tiny like this a few years ago. Back then it had been strange to have a living creature inside of her but with some practice she had quickly become accustomed to it.

Luna smiled in satisfaction as she sat still for several minutes relishing the feeling that Levi’s little bundle of chaos was creating inside of her.

Finally aroused, she began rocking her hips slowly in ever widening circles, each rotation sending shockwaves of pleasure radiating outwards from her core.

“Mmm don’t worry bro,” she purred. “This won't take us long at all,” she giggled breathlessly as her tight walls caressed and squeezed him from every angle.

Levi screamed as her pussy squeezed and grabbed him from all sides. Her hot insides were suffocating, her wet walls tried to push into every crevice he had. 

He could hear her delighted screams echo around him as his body was contorted by his sister's relentless thrusts. Levi vainly struggled against her the entire time, trying desperately to put an end to her using him as a common sex toy, but his efforts were futile. Luna dominated him completely, leaving Levi helpless in the grasp of her pleasure. 

The wet walls suddenly ceased their movement and he wearily collected his thoughts, his face pressed deep into her wet tissue. He could feel his raging erection trapped against Luna. The combination of sensations left Levi feeling both aroused and disgusted with himself. Suddenly he heard the loud scraping of the chair as she shifted it back and forth. Without warning her body started moving up and down. 

“No!” he screamed in her wet flesh, ignoring the trickle of her fluids that entered his mouth. “I’m not your fucking dildo!” he yelled out again in defiance but all he could make out was Luna's distant cries of ecstasy as her walls moved over his exposed body.

His sister moaned loudly as she rode up and down, faster and faster until Levi thought he could no longer take it. She rotated her hips fiercely as she brought herself closer and closer to climax.

Levi felt utterly humiliated as his sister's vaginal muscles forced his arms upwards over his head. He could feel the cool air blowing on his uncovered lower torso outside of Luna's tight confines until she slowly allowed herself to settle back down onto him again trapping him under her heated frame once more. His arms were painfully twisted due to her cervix pressing against them. 

He screamed for her to stop as her cervix rested on his head for a moment which forced him to his knees, until her wet walls slipped over him once again as she moved upwards. A loud moan reverberated around him as she clearly enjoyed herself until she suddenly crashed down on top of him again.

Levi expected the same motion, but suddenly the canal moved forward and his whole body was trusted forward. The fact that his legs didn’t snap in half was a testament of the shrinkapp as she bent his back in an awkward position and her pussy almost released his body.

Her moan was even louder this time as she moved him backwards again and he suddenly realized what she was doing.

She was riding him!

Luna let out a soft, almost guilty sounding chuckle as she started riding her brother. “Fuck this is hot” she sighed as she moved her pelvis forward again. Back and forth she moved, loving the feeling of her helpless brother inside her. The relative cool chair clung to her butt as she moved and she could picture him inside her.

“I hope you’re enjoying this as much as I am bro” she laughed and noticed she was out of breath already. She changed her rhythm again and started hopping up and down on her now favorite toy. 

The world clamped down on Levi as his wet prison became a vise. He could hear Luna cry out in passion as she rammed him as deep in her as she could manage. His arms were pressed against his head as her muscles kneaded him in her as hard as they could manage. He screamed and gargled in her fluids as she screamed in pleasure.

Luna lost control and came in a wave of pleasure. Her entire body shook as her muscles clamped down on her helpless dildo. Her helpless toy brother that was way over his head. 

Literally and figuratively.

Levi tried to scream again as his sister’s insides boiled around him, but couldn’t make a sound without swallowing a mouthful of her fluids. The oppressive inside guided his body in any way it seemed fit and he tried to get some control. He tried to kneel, to crawl, to fight his sister’s wetness, just to get one cool breath of fresh air. But there was no escaping his sister’s wet prison. 

Just as he thought it couldn’t get any worse, he noticed he still had a raging hard-on. And even worse, he felt an orgasm building up. 

“N..no, this can’t be happening” he thought as Luna moaned above him. “No, Luna, stop!” he yelled. The last thing he wanted was to cum in such a place. In such a humiliating state, reduced to his sister’s dildo. 

Luna, unaware of her brother’s impending orgasms, screamed in pleasure as a second small orgasm started to build. She moaned in approval as she felt his struggles intensify and bit her lower lip in pleasure. 

“Almost there bro” she whispered.

“No Luna!” he yelled as he could tell by the way she was grinding him that she was close. He felt so pathetic, his very existence nothing more than a common sextoy for his sister, yet in that very moment he was as aroused as he had ever been. The pure carnal feminine pleasure, even coming from his sister, was something he had never experienced before. 

“I.. I’m coming” he thought as his orgasm started, and just as he was about to accept the fact he was going to cum inside her, he suddenly was rammed by tons of muscles all around him, followed by a loud scream of pleasure coming from high above. 

“No!” he yelled as it canceled his orgasms and instead sent him in a state of panic as tons of flesh entered his mouth, ramming him back into his degrading reality.

Luna screamed in pleasure as a last wave of her orgasm washed over her. She slowly gyrated her hips on her chair, enjoying his last struggles until she finally decided to let him out. With a grunt, she moved her hips upwards and landed with a big thud behind her brother.

Luna catched her breath momentarily and put her hands on her hips. She smirked and giggled when she saw her brother between her legs. She reached down playfully ruffled his wet hair. 

Levi spat out a mouthful of Luna's cum and gasped for air, though he was grateful to be outside of his sister's cunt. He reluctantly opened his eyes, only to find himself wedged between his sister's thighs. Sticky liquid coated his skin and humiliation flooded over him as he was met with Luna's infuriatingly delighted expression.

“Did you enjoy this as much as I did?” she chuckled while catching her breath.

Luna grinned down at her tiny sibling. She found it adorable how completely covered in her juices he was stuck against her slit; she could feel his tiny movements tickle her sensitive skin and wiggled her hips playfully until a realization struck. 

“Bro..” she said teasingly. “Do you still have an erection?” After a brief fit of laughter, a mischievous thought crossed Luna's mind—one that would make Levi squirm in embarrassment even more than he already was.

“Tsk, tsk little bro” she said slowly. “No cumming in your big sis' she laughed and reached for her phone. The shrinkapp had a perfect feature for his current predicament. With a few swift motions and zooming in on his crotch, she quickly found his settings. 

Levi desperately tried to free himself from his damning predicament, but his body was awkwardly contorted and he didn't have a chance of getting out on his own.

"Get me out of this thing Luna!" he shouted in rage, as he laid helplessly beneath her. The humiliation of the moment was driving him crazy as she leisurely scrolled through her phone.

"Luna!" he yelled again, and she barely glanced down at him in response.

"One moment bro," she winked, before tapping something on her screen. Instantly Levi felt something change within his body, but he had no idea what it was.

"Hmm let's see," she hummed as she continued swiping away. "Permanent erection, check," she announced and Levi's blood ran cold.

"Aaand..." she sang as yet more pages flew by until finally finding what she was looking for - then pressing it with a satisfied smile. She quickly lowered her phone so that Levi could read what it said - and his mouth went dry.

"N..no Luna you can't do that," He begged when he saw the option she had just clicked: "Orgasm denial enabled".

She cackled high above him as he saw the torturous situation unfolding before him. "This is a great thing Levi!" She exclaimed as she prepared herself to extend his anguish further. "You still get all the pleasure...without ever having to release," She laughed.

Luna recalled when she denied a poor fellow orgasms for an entire week, pushing him past the brink of delirium. She bit her lip as she looked upon her weakened brother and his raging arousal; A mischievous smile creeping across her face - should she do the same to him? "It might help with his submission," She thought.

Levi looked at his towering sister above him, clearly in some kind of thought until she suddenly shook her head and started to laugh at him. Her breasts swayed gently with her laughs and her mocking face hung high above them. It was just unfair how much power she had over him. Almost as unfair as how much his body reacted to her utter feminine dominance. 

He tried to speak, but before his words could escape his mouth she had already pinned him down with her giant paw-like hands.

In an instant, her raging desire hung above him again, ready for another ride. She giggled in delight as she started a new round with him.

“Enjoy it Levi, just a few more orgasms should do the trick," she taunted as she lowered herself onto his helpless body.

An eternity later, what was an hour in reality, Luna finally had enough. She counted three more orgasms until her pussy was a bit sore. She could pace herself, she figured she had two more weeks of fun before they would return home. Plenty of orgasms to go and besides, she didn’t check once on her brother’s condition. She just left him in her steaming snatch between her orgasms until she was ready for more. 

“Poor Levi” she mentally chuckled as she pictured him inside her, all pent up and nowhere to go as his sister enjoyed her orgasms. But she was glad that he started to get aroused more and more. She’s seen this before with her first timers, the ones that selected her to be their first giantess. It takes some time getting used to being so powerless to a giantess. 

She grinned as his body plopped out of her snatch. Her name still clearly visible on his naked body.

She unclasped his body from her chair and gently grabbed him for a quick rinse. On her way to the bathroom she made sure she unbound his legs. She smiled softly at the tiny thing in her hands that gave her so much pleasure. 

“And the giantess being your own sister probably doesn’t help” she thought.

“Oh well” she thought as she ignored his tiny pleads and walked towards the bathroom. “Good thing we have a lot of time” she grinned and started to clean her brother so he could get some rest in his tiny apartment. 

The evening air was cool as Luna gently rinsed Levi off in her bathroom. He was limp in her hands, utterly spent from the day's relentless humiliations that both shamed and aroused him. The hot water washed over him, steam rising from his tiny body as it cleansed away the residue of his sister's indulgence.

She chuckled softly as her hands touched his erection. It would only return to normal if she would let it. The thought sent a naughty shiver down her spine and she made sure she gave it some extra attention. She enjoyed his little twists as he clearly reacted to the extra stimulation.

Satisfied, she carried him over to his tiny pink apartment, and without a word, deposited him inside.

Levi sat on his pink carpet and looked at his massive sister looking down on him. Her face was that of a girl who was fully satisfied. Her massive finger reached in and softly stroked his back. 

“Get some rest bro” she smiled down at her tiny sibling. She slowly brought her index finger to his crotch and gave it a gentle stroke, causing Levi to quiver in response. “I really enjoyed Today” she said as he suddenly realized he was still rock hard. “And I see you did too” she laughed.

“Oh Levi, you’re so lucky I found you” she said and giggled. “Just think we still have two whole weeks ahead of us” she said. 

Levi suddenly realized she didn’t change his settings. He would be rock hard all the time without being able to do anything about it. “Wait, Luna'' he yelled, but he was already too late. The tiny apartment slid back into the shrinkbox and Luna waved playfully as she retreated in her bathroom to get ready for bed, leaving her tiny conflicted brother trapped in his pink apartment.

Finally the morning came. He slowly opened his eyes and remembered the whole ordeal with Luna in a flash. With a grunt he got up and groggily walked toward the living room of the tiny apartment and noticed his raging hardon. He still felt aroused and groaned in frustration. 

He had tried to cum for an hour after Luna went to bed, but he didn’t succeed. He was stuck in his state of arousal and couldn’t do anything about it. Finally he just got into his tiny bed and after a while he finally fell asleep, a few hours of freedom from his dominating sister.

He noticed the light streaming through the miniature window, golden hues bathing the room in warm morning colors. He blinked against the brightness, realizing it was already late in the morning.

He glanced around, but Luna was nowhere to be seen. The room beyond his tiny apartment seemed empty, and a strange quietness hung in the air. 

“She probably started the day without me,” he thought. He didn’t know what to think of that.

Feeling trapped and ignored, Levi banged his tiny fist against the window, hoping to get someonés attention. But the sound was barely audible, swallowed by the vastness of Luna’s room.

Even though he was just awake, the silence and the absence of Luna were all so suffocating. Already boredom gnawed at him, stuck in his tiny pink apartment with almost nothing to do. 

Suddenly, the door to Luna’s room swung open, revealing a sweaty and breathless Luna. He hid behind the tiny couch as he watched her. She looked like she had just returned from a run, her face flushed and her hair sticking to her forehead. Levi watched from his window as she walked in, not even glancing in his direction.

Without a word to him, she disappeared into her bathroom. The sound of running water reached Levi’s ears, and he could only imagine her washing off the sweat, the cool water running down her body. He felt a twinge of envy, wishing he could have a bath, to be free of his confines.

As he hid behind the couch he was sure that she would take him out after her shower. He shuddered at the thought of her reaching in to do the next humiliating thing with her tiny brother. 

Finally she emerged in a light summer dress that fluttered around her long legs. She looked relaxed and carefree, a stark contrast to his own tense and confined state. Levi cursed himself for being so captivated by her grace as she gathered some things.

He tensed up as she walked towards him, but watched in silent shock as Luna simply left the room, not even giving him a second thought.

“W..what?” he whispered. This indifference somehow stung more than all her teasing and taunting. It made him feel more like an object, something she owned, than anything she’d ever done. 

“No, Luna, please wait!” he yelled and rushed towards his window. But her door clicked shut, leaving him stuck like that for how long she wanted.

However, unbeknownst to him, as Luna walked out of her apartment, a small smile played on her lips. She was well aware of the turmoil her little brother must be feeling. She wanted to give him a break, some space to process everything. Yes, she loved teasing him, having him at her mercy, but she also knew he needed time to adjust. Her steps were light as she walked away from the apartment, already planning her next round of games with her little brother.

“But that will come later.” she thought as she locked arms with her mother. 

“Let’s have lunch mom!” she cheered as they started walking towards a new restaurant in town.

---

Luna sat across from her mom at the bustling café, sunlight glinting off the glassware on their table. Her sandwich sat half-eaten on her plate as she lazily swirled the straw in her iced tea, her mind elsewhere. She leaned back in her chair, enjoying the gentle hum of chatter around them and the warm breeze brushing against her skin.

Yet, no matter how picturesque the scene was, she couldn’t stop her thoughts from drifting. Back home, her brother was trapped in the little pink apartment she had sealed him in. The image of his tiny, frustrated face pressing against the window of the drawer made her lips twitch upward. She imagined him pacing, yelling, trying to break free—utterly helpless and fully hers.

It gave her such a thrill. She felt alive, almost drunk on the power of it all. Just knowing he was waiting, knowing he had no choice but to endure whatever she decided to do next, sent a ripple of excitement through her. She crossed her legs and tried to suppress the bubbling heat in her chest.

“Luna? You’ve barely touched your sandwich,” her mom said, giving her a curious look as she cut into her salad.

“Oh, I’m eating,” Luna said quickly, picking up her sandwich and taking a bite. She chewed slowly, her eyes wandering to a group of people laughing at a nearby table. She caught herself smiling faintly. Were they laughing with friends? Or perhaps a sibling? Her smile faltered.

“Anyway, I’m so glad we’re doing this,” her mom continued, sipping her coffee. “With your dad leaving, it’s nice to have a little quality time together. We should make this a habit.”

“Definitely,” Luna replied, though her tone lacked conviction. She glanced down at her plate and adjusted the lettuce hanging off her sandwich.

Her mom chatted on about small-town life, a new store opening downtown, and a neighbor’s unruly dog. Luna tried to follow along, but her thoughts kept slipping away. The memory of Levi’s muffled screams from the night before surfaced, mingling with the faint trace of guilt that had been gnawing at the edges of her mind all morning. She shifted uncomfortably in her chair.

It wasn’t as if she was hurting him—not really. Sure, it was humiliating, overwhelming even, but she’d kept him safe. She always knew how far to push and when to pull back… didn’t she?

“...and I wonder if Levi’s having a good time with his friends,” her mom said, breaking Luna’s reverie.

Luna froze for half a second before casually reaching for her iced tea. “Yeah, probably,” she said with a shrug. “You know him—he’s always finding ways to keep busy.”

Her mom smiled wistfully. “I hope so. He’s always been a little restless, hasn’t he? Always pushing himself into something—adventures, new projects, trouble. I just hope he knows how to take a break once in a while.”

Luna’s stomach twisted, but she forced herself to nod. “Yeah, he’s fine, Mom,” she said, her tone a little too breezy. “You know Levi.”

Her mom chuckled softly. “True. That boy could find trouble in an empty room.”

Luna laughed lightly, though the comment hit closer to home than she cared to admit. Trouble was right—except this time, he hadn’t found it. She had brought it to him, packaged neatly in a shrinkbox and sealed with a smug grin.

Her mom reached for her coffee again, glancing at her daughter. “You seem quiet today. Everything okay?”

Luna quickly shook off her thoughts and smiled. “Yeah, I’m fine. Just thinking about… stuff,” she said vaguely, picking at the crust of her sandwich.

Her mom raised an eyebrow but didn’t press further. “Well, whatever it is, don’t let it weigh you down. You’re young—you’re supposed to be enjoying yourself.”

Luna smirked faintly. If only her mom knew.

They finished their lunch with light conversation, her mom none the wiser to the thoughts racing through Luna’s head. As they stood to leave, Luna glanced at the time. She felt a pulse of anticipation as they walked through the town square, the afternoon sunlight reflecting off the windows of the little shops. Soon, she’d be back home.

And Levi would be waiting.

---

Luna hugged her mom goodbye at the corner, watching her disappear into the small grocery store. "I’ll see you later," she called, her voice cheerful despite the storm of thoughts swirling in her head.

She wandered aimlessly through the sunny streets, her sandals tapping rhythmically against the pavement. The town was alive with vacationers, their laughter and chatter filling the air. Normally, Luna thrived in this energy, but today it only seemed to highlight her inner conflict.

The beach came into view, and Luna paused at the edge of the boardwalk, resting her hands on the railing. The warm breeze carried the scent of salt and sunscreen, ruffling her hair as she gazed down at the scene below.

A group of young men, about Levi’s age, was playing volleyball in the sand. Their carefree laughter and playful shouts struck a nerve. For a moment, she could picture Levi among them—tanned, grinning, and carefree, enjoying the holiday with friends instead of trapped in the pink confines of his humiliating little apartment.

Her stomach twisted. Was she taking it too far? Robbing him of his holiday entirely just to satisfy her own whims? She bit her lip, torn between guilt and the thrill that bubbled under her skin whenever she thought about him—tiny, helpless, and completely at her mercy.

Her cheeks flushed as she remembered his reactions, the way his body betrayed him with erections despite his protests. That had to mean he enjoyed it on some level, right? The thought made her grin despite herself.

Still, her conscience nagged at her as she turned away from the beach and wandered back into the bustling streets. She needed a distraction, something to get her mind off the mounting tension. Her feet led her to the sleek glass doors of a Shrinkbox Center, and before she knew it, she was stepping inside, the cool air conditioning a welcome reprieve from the summer heat.

She strolled through the aisles, letting the rows of gadgets and accessories wash over her. It wasn’t long before a familiar excitement began to stir. She spotted a new toy—a sleek, curved device that promised to enhance interactions with tinies. Luna picked it up, turning the box over in her hands, and a wicked grin spread across her face.

“This’ll be fun,” she murmured to herself, tucking it under her arm. But as she moved to the next aisle, something else caught her eye: a section of miniature clothing, perfectly tailored for shrunken people.

Her fingers brushed over the delicate fabrics, pausing on a fluffy dress that immediately made her smile. It was pastel-colored, adorned with tiny bows and lace, clearly designed for a tiny girl. At first, she imagined Levi in it, the sheer absurdity of it making her chuckle. But then another thought crept in.

What if it wasn’t for Levi?

Luna held the dress up, examining its intricate details. The idea of shrinking herself down and stepping into his world flickered through her mind. She pictured herself standing in the pink apartment, feeling as small and vulnerable as he did. Her cheeks flushed as she imagined looking up at her own room, seeing it from his perspective—a vast, overwhelming space dominated by her normal-sized self.

The thought was exhilarating. Would she feel as powerless as Levi did? Or would her size still give her the upper hand, even at double his height? She wasn't going to shrink down to his level..

She smirked, folding the dress over her arm alongside the toy. “Maybe it’s time to mix things up,” she thought. The idea of shrinking herself was tempting, a way to shake off her guilt while still keeping control.

At the register, Luna paid for her purchases, the anticipation building with each item scanned. She stepped back into the sunlight, the weight of the bag in her hand a reminder of the power she held—and the possibilities that awaited her back home.

As she strolled through the town, her eyes caught glimpses of couples laughing, families sharing meals, and kids playing. She sighed, her thoughts returning to Levi. Was it fair to keep him cooped up for the rest of the holiday, used solely for her pleasure?

Then again, she reasoned, wasn’t it also an opportunity for him? He’d never get an experience like this anywhere else. Her grin returned as she imagined his face when she unveiled the new toy—or when she stepped into his apartment wearing the dress.

“Just a few more days,” she thought, her resolve strengthening as she neared home. “I’ll see how he’s holding up and figure it out from there.”

Her pace quickened, excitement bubbling in her chest. Whatever doubts lingered, one thing was certain: she wasn’t done playing yet.

---

Levi sat on the tiny couch in his pink apartment, staring at the miniature television screen that blared some cartoon he didn’t care to watch. His arms were crossed, his expression sour, and his arousal still throbbing despite his best attempts to ignore it. His naked body felt hot against the soft fabric of the couch, his frustration mounting with every passing second.

Through the clear plastic wall of the apartment, he could see Luna’s massive room beyond—the same room they’d once shared as kids. The warm sunlight streamed in from the window, bathing everything in a golden hue. He could see a patch of clear blue sky above the buildings outside, a reminder of the world he was now completely cut off from.

His chest tightened at the sight. He should be out there, enjoying the summer, walking along the beach or grabbing drinks with friends. Instead, he was here, trapped in this ridiculous pink box like some kind of pet. Or worse—a toy.

The humiliating thoughts made him grind his teeth. He glanced down at his body, the small letters of Luna’s name still faintly visible on his skin, a cruel reminder of her dominance. And then there was the erection—relentless, frustrating, and utterly beyond his control. His body had betrayed him, and no amount of shouting or pleading with Luna had done any good.

“Damn her,” he muttered under his breath, pacing across the room. “Damn her and this stupid box.”

Suddenly, his thoughts were interrupted by the distant sound of heavy footsteps. They echoed through the walls, growing louder and more distinct with each passing second. His heart began to race, a familiar mix of fear and dread taking hold.

Then she appeared.

Luna stepped into the room, the sunlight illuminating her figure as she closed the door behind her. She was wearing a light summer dress that swayed with her movements, her bare legs seeming to stretch endlessly from his perspective. Her hair was tied back in a ponytail, a casual look that only seemed to emphasize her overwhelming size.

Levi instinctively took a few steps back, his stomach tightening as she crossed the room. No matter how many times he saw her like this, he could never get used to it. She was massive—colossal. Every movement she made, every shift of her body, felt like an earthquake from his perspective.

She moved to the bed and set down a shopping bag from the Shrinkbox Center, her expression lit with excitement. Levi watched, his mouth dry, as she began rummaging through the bag.

“What now…” he whispered, his voice trembling.

He watched as she pulled out a sleek box and studied it for a moment, her lips curving into a mischievous smile. Whatever it was, she seemed delighted. Levi could only imagine what new torment it held for him.

Luna opened her drawer, storing the box inside before pulling out something else. He strained his eyes, trying to make out what it was, but she moved too quickly for him to see.

Then, without warning, she turned her attention to him.

Levi’s breath caught in his throat as she approached the Shrinkbox, her massive bare feet thudding against the floor with every step. She knelt down in front of the box, her playful grin sending a shiver down his spine.

Her enormous face loomed in front of the clear glass, and her finger tapped lightly against the window. “Hello in there, little bro,” she cooed, her tone dripping with amusement.

Levi whimpered, instinctively stepping back as far as the tiny apartment would allow. The sight of her massive grin and sparkling eyes was both mesmerizing and terrifying.

She pressed a button on the side of the box, and with a mechanical whir, the entire apartment slid out. Levi stumbled as the motion jolted him, the walls of his little world pulling back to reveal the vast expanse of Luna’s room beyond.

He gasped as she stood up, her towering figure casting a shadow over him. The sheer scale of her body left him trembling, his tiny heart pounding in his chest.

“Well, well,” she said, placing her hands on her hips as she looked down at him. “What’s wrong, Levi? You look nervous.”

He opened his mouth to respond, but no words came out. Her teasing grin widened as she leaned forward, resting her hands on her knees to get a better look at him.

“Don’t tell me you’re scared of little ol’ me,” she teased, her voice dripping with faux innocence. “I mean, you’re already used to being so… close to me. What’s a little more fun between siblings?”

Levi’s legs wobbled as he stepped back again, his gaze darting to the pink walls around him as if they could somehow shield him from her. “W-what are you going to do?” he finally managed to stammer, his voice barely audible.

Luna giggled, her finger reaching out to gently stroke the roof of his apartment. “Oh, don’t worry, Levi,” she said, her tone playful but laced with an unsettling edge. “I’ve got something special planned for you. But first…”

She straightened up, her grin turning wicked as she moved back toward her drawer. Levi watched her every move, his mind racing with possibilities—and none of them were good.

Whatever Luna had planned, he knew it was going to leave him even more humiliated than before. And as much as he hated to admit it, a small part of him couldn’t help but wonder what she’d do next.

Levi paced in frustration across the plush pink carpet of his tiny apartment, the oppressive weight of his situation gnawing at him. The clear blue sky outside was mocking him, a stark reminder of his lost freedom. He glanced nervously toward the massive room surrounding him, wondering what Luna had in store. His erection, still stubbornly present due to her cruel settings, only added to his humiliation and frustration.

Then, with a thud of her bare feet, Luna returned to the Shrinkbox. He froze as she approached, his tiny body tensing up as her towering figure filled his vision. She bent down with that familiar playful grin plastered across her face, her massive hands rummaging in her shopping bag.

“Ready for your next surprise, little bro?” she teased, her eyes sparkling with mischief.

Levi’s heart sank as she pulled something out and let it dangle between her fingers. It was a tiny dress, impossibly small yet intricately detailed, designed for someone his size. The soft, pastel-colored fabric fluttered in the air as Luna giggled.

“Here, Levi,” she said with mock sweetness, dropping the dress through the apartment's open roof. It landed in a delicate heap on the floor in front of him. “What do you think? Isn’t it adorable?”

Levi stared at it, his face flushing with a mixture of anger and embarrassment. “What the hell is this?!” he yelled, his voice cracking. “You think I’m going to wear that? Are you out of your mind?”

Luna burst into laughter, her finger coming down to tap lightly on the roof of his apartment. “Oh, calm down, drama queen. It’s not for you,” she giggled. “I wouldn’t make you wear something that pretty.”

He blinked, confused. “Then why—”

Before he could finish, Luna stood up straight, a wicked grin spreading across her face. With a single fluid motion, she pulled her summer dress over her head, leaving her completely naked. Levi’s stomach churned. He immediately assumed he knew where this was heading.

“No… no, not again!” he shouted, stumbling backward. His mind raced with the humiliating memories of the last time she’d used him as her personal toy. “Luna, I swear—”

She bent down, her enormous body leaning over the apartment, and smirked. “Relax, Levi. That’s not what I’m planning this time,” she said, though her grin told him she was still having fun keeping him guessing.

She reached for her phone, tapping away with a practiced ease that sent a shiver of dread down his spine. He braced himself as the familiar hum of the shrink tech buzzed in the air. Before he could react, his body began to tingle and compress, shrinking down further until he was a mere two inches tall. His already tiny world seemed to grow even more immense, and he glared up at his colossal sister, his voice a mere squeak of protest.

“You’ve got to be kidding me, Luna!” he shouted, shaking his fist in frustration. “What now?!”

But Luna ignored him. Instead, she tapped at her phone again, a devious grin spreading across her face as she scrolled to her own profile. “Alright, little bro,” she said, sliding on another shrink watch and adjusting it snugly on her wrist. “Let’s have a chat.”

Levi blinked in confusion. “What are you—”

Before he could finish, Luna pressed a button, and the world shifted in ways he couldn’t have imagined.

To his utter disbelief, she began to shrink.

Her massive body, so overwhelming and dominant, started to dwindle before his eyes. Her legs, which had surrounded his apartment like towering columns, thinned and shortened. Her face, once so high above, came closer and closer to his level. The once-massive room expanded in every direction, and Levi’s heart raced as he watched the impossible unfold.

“What… what are you doing?!” he yelled, his voice trembling. “Luna, stop!”

But Luna only giggled, her shrinking form hopping gracefully onto the roof of his apartment before stepping inside. The walls seemed to close in around her as she adjusted to the confines of the tiny pink space. For the first time, she looked genuinely awestruck.

“Wow,” she murmured, her wide eyes scanning the apartment. “This is… so cute. And everything’s so big!” She hesitated, running a hand along the miniature furniture. “I mean, I knew it would be, but seeing it for myself… It’s incredible.”

Levi watched her nervously, his mind reeling. She continued to shrink as she moved around the room, her head brushing against the ceiling before her body became proportionate to the space. Finally, she stopped, leaving herself at roughly twice his size—around four inches tall.

She turned to him with a sheepish grin, her naked form towering over him even at her reduced height. “Hi, bro,” she said softly, a nervous giggle escaping her lips. “Surprised?”

Luna stood there, still towering over Levi despite her reduced size, her nervous giggles breaking the tension in the room. Her eyes trailed down to his naked body, and her smile widened in amusement.

“Still not used to being the one without clothes, huh, bro?” she teased, biting her lip to stifle another laugh. Levi flushed with embarrassment, his fists clenching at his sides as he glared up at her.

With a playful sway of her hips, she turned and walked toward the tiny dress she had thrown in earlier. Now, it was no longer tiny to her—it was perfectly proportioned, almost like it had been made for her new size. She reached down, running her fingers over the soft fabric, her eyes wide with amazement.

“Wow,” she breathed, picking it up and holding it against her body. “It’s so… big now. It’s kind of crazy seeing things from this perspective.” She glanced over her shoulder at Levi, a playful smirk tugging at her lips. “But don’t get any ideas. Just because I’m small now doesn’t mean I’m a toy. I’m still your big sister.”

Levi gritted his teeth as he watched her slip the dress over her head, her movements fluid and unbothered. She smoothed it down over her body, making sure every detail was in place, and then gave a little twirl, the skirt swishing playfully around her thighs.

“What do you think?” she asked with a giggle, striking a mock pose. “Not bad, right? Even at this size, I’ve got the looks and the power.”

He didn’t respond, his glare only intensifying as her confidence seemed to radiate even more. She didn’t seem fazed, though. Instead, her attention was drawn to the apartment’s tiny window. Luna moved toward it, her bare feet padding softly against the pink carpet. She leaned forward, resting her hands on the windowsill, and gasped as she took in the view.

Her massive bedroom stretched out before her like an endless landscape, every piece of furniture towering like a monument. She shuddered, a mix of awe and thrill coursing through her body.

“It’s amazing,” she murmured, her eyes wide. “My whole room feels like a kingdom.” She grinned, glancing over her shoulder at Levi. “Can you imagine? Seeing me at full size through this window, looking in at you? How scary must that be—to have a playful, dominant big sister watching your every move?”

Her words sent a shiver of frustration and anger through Levi. He’d had enough. Clenching his fists, he charged at her, his small but determined form rushing across the carpeted floor. Luna turned just in time, her eyes widening in surprise.

“Whoa!” she yelped, a laugh escaping her lips as he collided with her midsection. She stumbled back a step but quickly regained her footing, her hands instinctively pushing him away.

“Stop it, bro!” she giggled, easily holding him at bay. “You’re embarrassing yourself.”

But Levi didn’t stop. He stormed at her again, his frustration boiling over into a reckless attempt to assert himself. Luna couldn’t help but laugh, her hands darting out to catch him and shove him back once more.

“Please, Levi,” she said through her laughter. “You’re so tiny compared to me now. Just sit down and—ah!” She shrieked as he lunged at her again, this time with more force.

But Luna was still twice his size, and his efforts were in vain. With a swift movement, she grabbed him and easily pinned him down on the carpet. She straddled him, her knees pressing into the floor on either side of his body, and her hands held his wrists firmly against the soft surface.

“Stop it, Levi,” she said, still giggling. “You’re not going to win like this.” She leaned down, her face inches from his, her grin wide and teasing. “You know, this reminds me of when we were kids. Except back then, you used to pin me down.”

Levi growled in frustration, squirming beneath her, but she was far too strong at her current size. Luna chuckled, adjusting her position to sit up straighter, her weight keeping him firmly in place.

“Alright, alright,” she said, brushing a strand of hair out of her face. “Enough of that. Let’s talk, okay?” She gave him a playful smile, her fingers drumming lightly on his chest as she waited for him to calm down. “You’ve been through a lot, bro. Let’s figure out where we go from here.”
