Since the founding of the Tiny Raising club, there had never been such a tragedy as the raid that had just happened.  The current Demon Lord, Mao, had come for the Hero of the Human Realm, Yushia and the supposed Goddess that ruled over the universe, Megumi, who had infiltrated the school.  While their infiltration didn’t go unnoticed, Mao allowed them to wander until she grew bored of watching them desperately try to survive.  As punishment to the Tiny Raising club, founded by her younger sister, Mao didn’t harm any of the members, but led some of her sponsored students to destroy the hidden sanctuary for Tinies under the school, Mini-Garden, and crush and/or consume all the Tinies living within.

After humiliating Yushia by having him crawl on her body and try to arouse her, at the suggestion of her personal maid, Mao suddenly ran out of the sanctuary with Megumi, claiming that she was going to force the Goddess to teach her how to use the Sacred Treasure she had stolen when she took most of Megumi’s powers.  Mao left in such a hurry, she didn’t even bother finishing Yushia off, so before any of the other honor students could grab him, he was scooped up and brought into the clubroom by the Demon Lord’s kind and gentle sister, Mio.

Setting the tiny, armored man on the coffee table, the worried expression on the silver-haired Demon’s face only intensified as she glanced towards the door.  “I wonder if Megumi-san’s alright…?”  The chances of the weakened Goddess’ survival in her older sister’s hands were only guaranteed for so long.  “Even if Megumi teaches Mao how to use this ‘Sacred Treasure’, my sister isn’t one to keep her promises to Tinies…”

“G-Goddammit…”  Pacing back and forth on the large wooden surface, Yushia’s frustration furrowed his brow as he narrowed his eyes.  “...it’s difficult for me to even walk around the school on my own…  How am I ever going to rescue her…”  It was Megumi who had been with him on every step of his journey since the Demon Lord showed up in the Human Realm and literally blew his country off the map in a single breath.  All his friends and allies, all the innocent people were counting on him restoring Megumi’s godly powers so she could resurrect them.  But even more than that, while he had witnessed on multiple occasions Megumi’s disregard for human life, she was still a good person at heart and far better than the Demon Lord bent on complete human extermination.  “Can I even rescue her?  I couldn’t even get the Demon Lord to notice me when I tried!”  If only he were stronger.  He might have been the mightiest human in history, but that doesn’t amount to even a bug’s strength in the Demon Realm.  He had been trying his best to follow the Demon Lord’s orders, but…  “I wonder why the Demon Lord became so flustered all of a sudden, though.  It seemed to me like she just started panicking out of nowhere…”  When she tossed him out of her dress, he was so confused.

“Oh, that was your fault.”  Despite the serious nature of their conversation, the towering, bespectacled girl couldn’t help but find the amusement in his obliviousness.  “Only that clueless maid wouldn’t catch on to what was going on.”

Looking up, Yushia was confused.  “…?  That can’t be right… all I did was follow the orders she gave me.  I couldn’t even do anything else…”  The Demon Lord even said she couldn’t feel him at all.

“It was the maid who suggested those orders.  My sister herself can’t actually handle lewd stuff very well.”  Even with everything that was happening, she wouldn’t forget the troubled expression on her sister’s face for as long as she lived.

It took a few seconds for Yushia to register what he had just heard.  “Can’t handle lewd stuff…?!  Are you serious?!”  Remembering the overly flirtatious behavior, the ‘everyone look at me’ attitude, the low cut, strapless, short gothic-lolita inspired dress, the Hero couldn’t believe his ears.  “With that personality?!  And that outfit?!”  Where was that concern when she was towering over him?  “She had no problem flashing her underwear at me!”

Nodding her head and crossing her arms under her sizable chest, she could understand his confusion.  “My sister has been a prodigy for as long as I remember, constantly surpassing all her peers in all fields.  But she had one major weakness… that is, her fear of anything sexual.  Not only is she far more sensitive than most people, but she has no such knowledge.  And with her pride, she can’t exactly ask people to teach her at such an age…”  Today was the first time she had seen the prideful girl so flustered, so despite everything, it felt good to watch her squirm.  “I didn’t think she was THAT sensitive, though…  Normally, a Tiny of that size can’t make us feel anything no matter what they do.”

“I-I see…”  Turning his gaze downward, this was just the latest in a long list of reminders of how small, weak and insignificant he was when compared to Demons.  “I mean… I WAS smaller, but you didn’t need to add that last part, did you?”  There was only so much a person’s pride could take.  “By the way, it seems that quite a disaster befell you as well… the cities are all in ruins, and from the looks of things, there are next to no survivors…”

“Yes… it was a tragedy.”  Caught a bit off guard that he would spare concern for her after what happened to Megumi, she was reminded once more of how different Yushia was to other Tinies.  “Though I wasn’t anywhere near as personally attached to the Tinies we lost as you were to Megumi…  I wish there was something I could do for him, but directly challenging my sister would be like him trying to fight me…  I doubt she’d even notice while holding back.”  Her own sense of powerlessness sinking in, she needed to look on the bright side.  “I did miraculously manage to save about 10% of the Tinies, though.”

“‘Managed to save…?’  Oh, I see… you hid them somewhere?”  In all that confusion during the attack, that she was able to save any humans was a great accomplishment, a miracle even!  “That’s great news!  Mio really does care for humans.  Now if only she could do something about treating them like pets…”  He knew it wasn’t malicious, and in all honesty the thought to a Demon of truly treating humans as equals would be as ridiculous as a human treating a colony of ants as equals.  “Ah…  comparing humans to ants…”  Truly, his time in the Demon Realm was corrupting his sense of significance.  “But… where?  That’s a lot of people to hide…”

Avoiding direct eye contact, the crimson-eyed Demon began to sweat nervously.  “They’re…  ‘In my belly’.”

“Y-your belly?!”  Shocked, Yushia took a couple of steps back away from the gigantic girl.  “How was that ‘safe’?  Sure, if not her, it would have been another student, but still that wasn’t ‘saving’ anybody!”  Growing nervous, if she decided to do the same to him… there was nowhere he could run on the big, empty table.  “You mean you ate them?!”

“N-no!”  Taken aback by the misunderstanding, Mio frantically tried to explain herself.  “I hope he understands…  I didn’t have any other choice.”  Taking a breath to calm down, her cheeks began to bloom a bright red.  “More specifically, they’re in my… uterus.”

The shocks just didn’t stop, coming one after another for a tiny Hero.  “U-uterus?!”

Nodding, since he seemed to be taking it well, she sighed in relief.  “Just before my sister found this place, I hurriedly shrunk a few cities and stuffed them in my womb…  Seems like it worked pretty well, actually.”

While he couldn’t argue with the results, that was only in hindsight, not to mention the effect it must have had on the people she ‘rescued’.  “Was there seriously no other place you could think of…?  But… just how many people are inside her and she acts like they’re not even there…”  His eyes falling to her lower abdomen, Yushia didn’t know how many humans were being sheltered in her womb, but it had to be more than his village, and yet he never would have guessed if she didn’t tell him so.

“Not just my sister, but that maid as well are both frighteningly sensitive to the presence of Tinies… they’d find out in an instant if I hid them poorly.”  She also knew how ridiculous of a strategy it was, she wasn’t even sure it would work, but she desperately wanted to save those that put their trust in her.

“Oh…”  He knew she was right.  Through her actions, Mio had proven herself an ally of humanity.  She wouldn’t do something to harm them if she could help it.

“But… the only problem is that I can’t communicate with the people inside.  After all, even with so many shrunken Tinies living inside me, the most that I can do is feel their presence.  Conversation is out of the question.”  Placing a hand on her stomach, she smiled gently knowing they were safe, but there was genuine concern in her voice.  “At this rate, I’m worried that they might die from the harsh environment…”

Nodding, he could tell this was a serious issue.  If not the crushing muscles, some Demon’s sexual fluids are corrosive to the touch for humans.  Even if she was able to do something about those, there were other issues to consider too.  “I see…”

Fidgeting in place, a small smile returned to her face as she glanced in his direction a couple of times.  “That’s what I wanted to discuss.”  Her heart fluttering at what she was about to ask, Mio thought about the attack again.  “This might actually be a bit of a blessing.  Since it’s HIM.”  With escaped Tinies running around all the time, even if every single Tiny in their club got slaughtered she could always start from scratch again, but Yushia was different.  “Could you maybe, um…  Get inside my belly and confirm how everyone’s doing?”  Her face threatening to catch fire it was so warm, she tried her best to maintain her composure.

“What?!”  His blue eyes wide in surprise, Yushia looked from the bespectacled beauty’s face to her skirt-covered crotch a couple of times.  “Get inside… your vagina?!”

It was more embarrassing to ask than she thought it would be, but she couldn’t back out now.  “E-essentially.”  With a slightly more confident smile, she put her hands on her hips.  “If you like what you see, I could let you live there too…”  She had teased Tinies before in the past.  It was adorable to see their confidence falter with just a bit of provocation, but with Yushia it made her heart race like never before.  “With Megumi out of the way, if I could get Yushia to join me…  I mean… he’s so much stronger than other Tinies.  The strongest I’ve ever met.”

“... Live?  Inside of Mio…”  Leveling his gaze at her crotch, the white cotton of her underwear peeking out from behind the black veil of her uniform, he thought of the warm lips opening to accept him.  “I wouldn’t have to worry out getting crushed or have to outrun some monstrous sex toy to survive…  I could just disappear into her vagina, forever…”  Though, as appealing as the thought of being able to put down his burdens were, he was still a Hero.  “I-I’ll pass on the luxury…”

However, the moment of reflection wasn’t something she would overlook.  “He hesitated there… he must be worried about Megumi.”  Misunderstanding his motives, she quickly though of a counter offer to get him to do her this favor.  “If you’d help me, I’ll help you retrieve Megumi in return.  Please…?”  “I’ll have more chances to appeal to him if we work together… and I really don’t want to leave Megumi alone either.”

“Alright.  Should be easy enough.”  Not just the people inside of her, but even Mio herself was in need of his help.  What kind of Hero would he be if he refused?  Still, he couldn’t help but feel like he lost something in return for every time he ‘helped’ a Demon with one of her ‘problems’.  “Honestly, all I seem to be doing is exploring girls’ bodies…”  From getting the Hi-estrogen to helping Mamori and even just recently with the Demon Lord, he was getting good at navigating the female body now…  “Though at least I’m good at THAT.”

Sighing in relief while cheering internally, she smiled gently down to him.  “Thank you so much!  I’d also like you to pass this transceiver to the people inside.  They’ll understand if you show it to  them.”  Handing him a small rectangular object of plastic and metal, realizing what she needed to do next, she hesitated for a moment.

“The technology in this world never ceases to amaze me.”  Putting the ‘transceiver’ in one of his pockets, Yushia had long come to terms with how primitive the Human Realm was by comparison.  “If we could get weaker versions of the weapon they used on the girls in that locker room, if another Asmod-er… if another cockroach appeared the people wouldn’t have to worry.”

Taking a moment to calm her emotions, Mio turned around.  “Alright, then please come this way…”  Reaching up under her skirt and bending over a bit, the twin-tailed Demon pulled her panties down just enough to expose her fair, smooth backside and the pretty, pink velvet folds between her legs.  Pressing her legs against the edge of the table, she reached back with a hand and pulled up the back of her skirt a bit.

“Alright… let’s get thi-!”  Sighing in self-deprecation for himself, when Yushia lifted his head to see the position she had taken, his mind went blank.  Pale white cheeks as flawless as silk, plump and round as a gargantuan peach dominated his entire field of view, with the puckering wrinkle of flesh set in the center of them.  Below it, resting on the wood through the bunched up undergarments, the soft, puffy mounds of her vulva squished out from her slight weight pressing down on them, spreading the moist petals of her sacred flower which acted as the portal to the sanctuary of the Tinies she hurriedly rescued.  “Megumi was an impressive view, but this…  this is…”  Slowly walking forward, it wasn’t his duty to reestablish contact with the settlement sequestered away in the gorgeous giantess that made him move.

Staring back over her shoulder, Mio was doing her best to suppress her blush, smiling at the arousal plastered across the Tiny Hero’s handsome face.  “He’s staring so passionately…  This is more embarrassing than I thought, even if he’s a Tiny, he’s still Yushia.”  Her views on Tiny rights notwithstanding, that didn’t mean that she, or her club members, didn’t still ‘play’ with Tinies.  However they were always criminals and ne’er-do-wells, or the occasional accident.  She did still have a throne that overlooked all the miniature cities they had built after all.  And yet, with Yushia she couldn’t muster her usual indifference in such a compromising position.  “Y-you may get in now…  By the way, I placed a Shrinking spell on the inner walls, so you’ll be steadily getting smaller as you go deeper in…  Please be careful.”

However, Yushia hardly registered what she said, as he reached out and touched the lustrous skin she had laid bare to him.  Even at his relatively smaller size in comparison to her, his hand depressed the surrounding flesh slightly and her warmth passed into his palm.  “Even though I’ve been traveling with one…  For the first time it feels like I’m standing before a Goddess…”  Looking up the slope of Mio’s butt, he didn’t even think as he began scaling the building-sized derriere.

“Huh?  W-Why is he climbing my butt!?  Does he like girl’s butts?  I-I don’t mind, it’s just…”  Feeling Yushia climb onto one of her exposed butt cheeks, Mio was happy that he couldn’t see her face for the blush that dominated it.  Both happy and embarrassed, she wanted him to deliver the transceiver to the Tinies in her uterus quickly so she could check in with them and go rescue Megumi before it was too late…  “But they can wait just a couple minutes longer.  I still need to reward him for all the help he’s been so far.  I can let him get away with this much.  I just hope he doesn’t fall and hurt himself.  But if this gets him to decide to live with me…”  Giggling internally thinking of living with the handsome hero staying in her panties throughout the day, she wouldn’t mind if he didn’t.

“It’s so soft and warm…  and BIG!”  Clinging to the girl’s rear, Yushia nestled his cheeks against the inviting flesh and inhaled deeply of her comforting scent.  All his worries and doubts seemed to fade with every breath he took, but mixed in was a heavier aroma that he found intoxicating.  It was distinctly different from the atmosphere of her natural odor, sweat and whatever lotion she used, but it wasn’t the pheromone laced scent of a woman’s sex like he had experienced before.  Crawling a bit closer to the crevice that divided one cheek from the other, the smell became more and more potent, and once he peeked over the crest of her inner glute, the sight of a tightly puckered anus, glistening with natural oils and lubricants but otherwise clean, told him where the pleasingly foul smell was coming from.  “That can’t be…  Th-That a…  a…”  Unable to accept the fact that the intoxicating scent was produced by her backdoor, Yushia couldn’t deny that it was coming from somewhere in the area.  “I could always just…  climb closer to check?  No.  No, no, that’s crazy.  What if she feels me?  Or worse, what if she doesn’t?  If she clenches?  Will I die?”  A clearer head prevailing as he exhaled, Yushia was about to climb down towards the waiting vagina when he took another breath.  “Then again…  I’d likely survive.  I mean, with everything I’ve been through, a girl’s butt isn’t going to be the thing to kill me, right?  I’m still a Hero!”  Emboldened by the powerful fumes, Yushia climbed closer to confirm if her anus truly was the source of the heady scent.

“Whoa, whoa!  Yushia?!  I’m not completely oblivious to you climbing on my butt you know!”  Feeling the Tiny man willingly crawl closer to her butthole, Mio decided she needed to stop him before it was too late.  “H… Hey!  That’s the wrong hole!!  Geez… if you get in there I’ll pucker up and crush you!”  Whether it would be intentional or reflexively, she recalled a Tiny criminal who almost drowned another in a toilet she once punished by making them clean her anus.  They hit a sensitive spot while cleaning and her anus puckered around them, crushing them into a paste instantly.  She never meant to kill them with that punishment, but it taught her just how careful she needed to be when handling Tinies.  “At least warn me first.  I don’t hate perverts if they’re someone I like, so if you die in my butt I’ll be REALLY upset.”  Unlike her older sister, she had a healthy interest in sexual acts, and one errant comment about her having a ‘stick up her butt’ later lead to a perverted, delightful discovery.

Her warning coming as a surprise to him, Yushia tightened his grip in a mild state of panic getting caught.  “Oh cra-ahhhhhhh!”  Given his position just at the rim of her anus, when he clenched his outstretched hand, Yushia squeezed close enough to get a reaction out of her body.  The walls of butt flesh suddenly came closing in fast, catching him between them as the quivering orifice puckered like she had warned and drew his arm inside.  The marshmallowy soft, plump and bouncy flesh turned hard as iron for an instant, shattering every bone in his arm and her tightened butt muscles nearly crushed his body.  “AAAAAAAAAAAAAAHH!”

Hearing the scream of pain coming from her backside, she let out a sigh of relief as her hands were holding her butt cheeks apart.  “Phew…  That was too close.”  Relaxing her clenched muscles, she felt Yushia free his arm from her sphincter and her heart fell.  “I’m so sorry, Yushia.  But you should know better than to play with a girl’s butt like that.  If you became my familiar or something, that would be a different story… and while I’m sure you’ve learned your lesson...”  “Yushia.  I don’t mind if you want to keep pushing your luck and play around back there, but could you please deliver the transceiver first?  Honestly, I’d rather not have to send one of the girls inside me if I can help it.  You’re just lucky I caught myself in time.”

Feeling the healing magic of his spell repair and restore his body, the guilt of giving in to his baser instincts and the shame of almost dying to a butt twitch hit the Hero mentally and emotionally harder than the physical trauma had.  “Mio saved my life just now… saved the HERO’s life from her reflexive twitch.  Heh, some Hero I turned out to be.  Risked my life and almost died fighting what is vermin over here.  While I can accept the women here being able to kill me so easily, there is usually a clear intent to do so.  Sure, they may not value my life or think of my existence as significant, but even getting treated like a bug and stomped on would be a more dignified death.”  The heaviest toll taken on him throughout his journey had been on his ego and self worth.  This was just the final act needed to make him see how weak he truly was.  “And yet I thought I could rescue Megumi?  That I could help her reclaim her Sacred Treasure and bring everyone back?  Ha!  No…  but there IS something I can still do for Mio…-san.”  Silently climbing down to the Demon’s tender folds, while he wasn’t able to open them further for easier access, Yushia was able to squeeze through the small opening that her setting her weight on the table had opened for him.  “My last act as humanities ‘Hero’...”

Inside Mio’s Uterus

Thankfully Mio’s vaginal tunnel opened up more once he was past the threshold, though the journey deeper into her took longer the smaller he got.  Her potent scent was laced with arousing pheromones, and the liquid that oozed over him and entered his mouth had his lust burning stronger than it had ever before, but the phantom pain from the recent incident kept his mind focused on the task at hand.  By the time he had reached her cervix, he was having to pull himself over each little bump and ridge of her slick inner flesh.  By the time he slipped through the opening in her cervix, he wasn’t even sure how small he had become for the cavernous chamber that stretched out in front of him to seem so huge.

“This is… the club president’s uterus…  It’s very… how do I put it…?  Grotesque… and yet beautiful.”  While the air was saturated in her scent, it wasn’t as noticeable as the path he just took and the environmental conditioning magic permeating the space kept the temperature lower than her body heat.  The squishy ‘ground’ secreted little pools of her vaginal fluids, but thankfully her juices were not acidic, though he wasn’t sure if that was through nature or magic.  “Everything’s so damp and sticky… is it really okay for people to live in this environment…?”

Dwellings and structures of squishy tissue rose from the undulating floor, moist to the touch and glistening from the ambient, magical light illuminating the Demon girl’s most private area, and large rivers of her slimy fluids blocked off routes that led deeper still into her body.  The town didn’t even reach the back of her womb, placed right was the entrance and stretched no more than a relativistic couple hundred feet or so.

Walking through the settlement, the people were of mixed opinions, some coping fine or finding the experience interesting, mostly the girls, or slowly breaking down if not getting sick in a hidden corner somewhere private, mostly the guys.  There was an omnipresent feeling of comfort and security spread in the air that brushed against Yushia’s magical defenses.  “She probably set this up to try to keep everyone calm, but if it were stronger I think it would brainwash everyone into her slaves.”  Taking the silver haired girl’s personality into account, he ruled the possibility of her doing something like that out.  “That said, if it wasn’t for this safe haven, all of these people would already be dead and/or digesting…”

Entering a larger building towards the back of the town, Yushia found a man who looked like he was in charge.  As he approached, the man noticed him.  “...what is it?  I’m busy.”

“I wanted to give you this.”  Pulling out the small box he received from Mio, Yushia hands the man the transceiver.  “You can’t contact the outside world without this, right?”

A look of relief softened the man’s hardened features once he saw the box.  “Oh!  Thank you…  I was getting worried because I thought the Mio-sama forgot about this…”  Taking the piece of technology, his hands trembling with overflowing gratitude and solace.  “So she did just forget it…  Thanks a lot.”  Wiping some tears from the corner of his eyes, he composed himself, putting the transceiver in his pocket.  “How are things outside…?”  His expression becoming grim again, his concern for those who weren’t as fortunate as them was evident.  “I imagine all the cities are…”

“Right…  Well, there’s nowhere to hide out there…”  Unable to maintain  eye contact with the man, Yushia gaze lowered to the floor.  Scenes of the attack flashing through his head as he hadn’t had time to process what had happened, it went by so fast.  The destruction, the death, the appetites…  “M-Maybe…  Maybe a human’s place really is…”  While not ideal, at least the people in Mio’s uterus were safe.

“I figured as much…  That means our only option for now is to keep living here.”  Touching one of the slick walls, the man pulled her hand away, creating threads of viscous liquid to stretch out with it.  Looking at the mess on his glove, he just sighed and wiped it off on his coat.  “Maybe we’ll get used to it with time…”

His job done, Yushia turned to leave, glance over his shoulder for a moment to look at the man once more.  “Y-Yeah… hopefully…”

Tiny Raising Clubroom

After a couple minutes of no longer being able to feel Yushia inside of her, Mio was starting to get a bit nervous.  Because she had to contend with her prodigy sister and that sadistic maid, she had to shrink the city and Tinies so small that, if not for the fact that they were all grouped together, even she wouldn’t have been able to tell they were in her.  “Oh~!  Oh, I can feel him again…”  Thankfully, she could feel a Tiny slowly growing larger as they made their way out of her vagina.  Looking back without pulling up her panties, she was relieved to see the blonde head of hair as Yushia tried to wipe her fluids off of him.  “… W-welcome back…  Sorry for asking you to do this.”

“D-don’t worry about it.”  After realizing the futility of his actions, Yushia just accepted that he was going to be soaked in her sweet tasting nectar, and was surprised to see her still presenting her rear to him.  Once more he basked in her beauty, even still admiring the quivering orifice that almost snuffed out his life.

“...By the way… how were things inside?  Is everyone there comfortable?”  Trying to keep the conversation going so it didn’t seem weird she wasn’t fixing her state of undress, she did place a hand on her stomach and rubbed it a bit.  “It’s pretty tricky keeping them safe from my magical energies in there.  Too much and they’ll lose their minds.  If that were to happen, they’ll do nothing but mindlessly offer themselves to me as food or toys…”

Thinking about what he saw, Yushia wasn’t sure how to answer.  “Err… well…  More or less comfortable, I guess…”  While there were a couple people that were taking it a bit too hard, more people were at least content and grateful to be alive, understanding that Mio had their best interest at heart.  “Honestly… I think it might be a bit too comfortable in there…  Is it too late to take her offer?  Should I ask her?”  Oblivious as he was to the advances of women, Yushia was able to recognize the silver haired Demon’s offer to live in her earlier as a joke.  Lowering his gaze, he contemplated asking her if he really could.

“That’s good to hear…!”  Sighing in relief, she was afraid the Tinies may have resented her for what she did or had already gone insane.  It had only been a little bit since she rescued them, but she wasn’t sure how long it would be before she could find a safe place for them and let them out.  “They should have enough supplies for a while, but I’ll have to… hmm?”  Noticing Yushia's pensive face, she put the thought of the other Tinies aside.  “…  Um, Yushia?  Is everything alright?  You seem to be a bit depressed.  Are you worried about Megumi?”

[Ask Mio to be her pet?]

[Yes]     [No]

[Yes]

“Huh?  O-Oh, y-yeah, yeah…  There is that, but Mio-san, can I still take you up on your offer?”  Snapped out of his deep thoughts, he asked her without a hint of doubt.  “Or if not, I wouldn’t mind living with Mamori-chan either…”

Initially shocked at his request, the gigantic girl quickly whirled around and crouched down to bring her face level with the table top.   “R-Really?  You wouldn’t mind?  Why the sudden change of heart?”  She could barely contain her excitement.  “Does it really matter?  With this, Yushia will…”

“Heh… I suppose it does seem a bit sudden to you, but honestly it took me WAY too long to realize how weak I truly am…”  Shaking his head and shrugging his shoulders, Yushia was done pretending at this point.  “Since your sister heard, I’m sure you’re aware that in the Human Realm, people were saying that my party and I ‘defeated the Demon Lord’, right?”

Thinking for a moment, Mio did recall her sister mentioning something about teaching the humans a lesson not too long ago.  “Why would you tell such a silly lie like that?  You should know you stand no chance against Mao.”

“It wasn’t a lie… we were just misinformed.”  His face cracking into a dark grin, Yushia couldn’t help but laugh at his hubris and incompetence.  “What we THOUGHT was a Demon Lord, the monster my party and I were only barely able to defeat after sacrificing an ancient artifact from the Goddess… was nothing more than a cockroach from the Demon Realm that happened to find a crack in space and come to the Human Realm!  Can you imagine my surprise when I saw monsters as powerful as my greatest adversary getting stomped on and casually squished by a child playing in one of your parks?  After that… well trying to accomplish even the most basic of tasks here require all of my strength, if even that is sufficient at all.”

“Yushia…”  She could see how his adventure in the Demon Realm had thoroughly and mercilessly crushed his confidence and ground it underfoot.  Despite most Demons saying Tinies are worthless, so many go out of their way to humiliate them in such cruel and twisted ways, so she could only imagine the strain that put on his want to protect the weak.  Worse yet, she seemed to be the final straw that tipped him over the edge.

“There are a couple other Demons that said they owed me and Megumi a favor too…  So if neither you nor Mamori want to take me in, I could try to reach out to them.  However, I don’t think they’d exactly be careful with me.”  He had seen first hand the fate of people that tried to survive in the wild.  How settlements even exist with monsters like those cockroaches roaming around was beyond him.  “I don’t want to die though, but I get it now…  Humans are… humans are just Tinies.”

Gritting her teeth, the crimson-eyed girl slammed her hand on the table in frustration hearing him say such things.  But her frustration wasn’t directed at the downtrodden man, rather the society she lived in that reinforced such ridiculous notions.  “It’s not Yushai’s fault.  He tried so hard and has seen too much!  He needs someone to protect him, but more than that, he needs…”  Looking at the trembling man, fear twisting his handsome face, her anger evaporated and she took a deep breath to calm down.  “Sorry, Yushia.  I didn’t mean to scare you like that.  While it may be true that, compared to Demons, your physical and magical might may seem insignificant…”

“Yeah… I get that already…”  Having her tell him what he already knew didn’t make it any easier to accept, but he couldn’t deny her words.  It was the truth.  “I’m far too wea-”

“...there is something you possess that no Demon I’ve ever met could compare to you in, not even my older sister.”  Seeing him snap his head up to look her in the eyes, a faint hope glimmering behind them.  If she were any other Demon, now would be the perfect opportunity to crush what little of his ego he had left and make him into an obedient slave or snack.  “If I tear him down just this once, I could have him rely on me and me alone for the rest of his life.  I could have him all to myself…”  However, Mio wasn’t like other Demons.  “You know, there used to be a third student here that was a real menace.  She would go around tormenting Tinies in grand public displays and used her family's power and influence to make the other student’s lives miserable.  She was confident that she could do ANYTHING.”

Reflecting on his time in the school, Yushia had met and seen a fair number of the students and staff, yet he couldn’t think of anyone that matched the one she just described.  “What happened to her?  Did she piss the Demon Lord off or something?”

“No, my sister didn’t care about her at all since she never did anything to disrespect her.”  Shaking her head, Mio just smirked.  “Have you met the scholarship student everyone calls ‘Marshmallow’?  Plump girl with white hair?”

“Y-Yeah…  She’s who we got a code for something from.”  She was a pretty memorable Demon, to say the least.

“Well one day this girl was making a display of crushing some Tinies in the main entrance.  Marshmallow grabbed a bunch and ate them because she was hungry.  The senior didn’t like that and started yelling at Marshmallow for ruining her demonstration.  I guess Marshmallow just had enough or wasn’t in the mood for it.  She got a Minimum spell off on her and shrunk her right there in front of everyone.  Suddenly, this overconfident, arrogant girl was the size of a Tiny and standing in the palm of Marshmallow’s hand.”  Just remembering the look on the girl’s face as she stared up at the white haired, chubby younger student was enough to bring a smile to her face.  That senior was a menace to everyone around her.  “At first she demanded Marshmallow undo the spell, but, unsurprisingly to anyone watching, Marshmallow simply told her that she was still hungry and licked her lips.  Suddenly, it wasn’t okay to eat someone just because they were smaller.  NOW it was wrong and murder and she asked Marshmallow to let her go and begged for anyone to come to her rescue.  Marshmallow then sighed and said she sounded exactly like every other Tinie she’d eaten before and ate her right there.”

He had overheard one of the other students say that the gluttonous girl had eaten classmates before, but he didn’t think she’d do it so brazenly.  “What!?  But wouldn’t she get in trouble for that?”

Mio shook her head.  “No, like I said, Mao didn’t care about her one way or the other.  Marshmallow got a free pass and there was nothing anyone else could do about it.”  Shrugging at the blatant bias, there was nothing she could have done about it.  “I heard she got called into the office a couple days later when the girl’s parents came in to complain.  Apparently she left licking her lips and the parents weren’t seen leaving.”

“O-Okay… but what does that have to do with me?  That story just proves how weak and little I am…”  He was foolishly hoping she’d compliment him somehow…  “I guess not even Mio-san can…”

“No, if anything, it proves how easy it is to think you’re strong just because you’re bigger.”  Not letting the blonde Hero sink any further into despair, the gentle Demon instead wanted to reassure him.  “You say you almost died fighting a cockroach?  Well I don’t think anybody in the Demon Realm would even try to fight one if they were as small as you are.  It’s that persistence of yours, that mental fortitude and courage that makes you stronger than any other person I’ve ever met, Yushia.”  While it was true she still saw him as a Tiny, that didn’t mean she didn’t respect his strength of will.  “Other Demons don’t even think about opposing my older sister… I didn’t either, not directly anyway, but even after witnessing her power, YOU still did.  Demons have it easy, but really, we’re all that third year girl who haven’t met our ‘Marshmallow’ yet like you have.”

Hearing her compliment his courage, light returned to Yushia’s eyes.  “Actually, she’s right about that…  Those two girls Megumi defeated in the Human Realm just cowered before her once they were small and she was big.”  It wasn’t about being ‘weak’ or ‘strong’, Demon’s just happened to get a better lot in life.

“But that said, not knowing your limits is just foolish, not courageous.”  Smiling now that she had succeeded in raising his spirits, the silver haired Demon wasn’t about to let her chance pass her by.

“Did you really need to add that last part?”  His smile fading, he sighed and shook his head.  “Though she’s not wrong.”

Her playfulness fading from her smile, Mio tried to keep the nervousness from showing on her face.  “Hey, Yushia…  Do you want to become my familiar?”

“Familiar?  You mean like one of those magically bound pets?”  Not entirely knowledgeable on the concept, he did remember Maezi telling him about them before.

“Well… Yes and no?”  It was difficult to explain the subtle nuances of a Master/Familiar relationship, and while overly simplified he wasn’t entirely wrong.  “You would become subservient to me in exchange for some magical benefits.  But most of all, if you were ever in trouble I’d become aware of it and could teleport you to me.”  Highlighting the appeal of a Familiar contract, she tried to entice him into accepting.  “Besides, even IF you did have to serve under me, do you think I’d be a cruel Mistress?”

Blushing at the thought of the kind and gentle Demon being his Mistress, the only tasks Yushia could think of her giving him, so long as he didn’t do anything to upset her, would likely have to do with rescuing and sheltering the Tinies of the world.  “Not at all…  If anything, it feels like you’re getting the worst end of the deal.”  Chuckling, he scratched the back of his head.  It was an enticing offer.

“Well… normally I wouldn’t ask a Tiny to be my familiar… and you’d get some special perks given your accomplishments…”  He didn’t seem to be hesitant or resistant to the idea, but he hadn’t agreed yet either.  “Or do you not want to?”

It wasn’t the hard of a decision for the blonde man.  He had already accepted that he couldn’t continue on as a Hero any longer, so this seemed like a perfect position for him.  Smiling up to her, he only had one more thing to ask.  “How do I sign up?”

Joy bubbling up from the pit of her stomach, she restrained herself from jumping up and down just yet.  “The ceremony has been simplified since ancient times, so all you have to do is prove your subservience to me and I can take care of the rest.”  Picking Yushia up, she brought him to eye level.  “Also, since this might be important to you, a Familial Pact is a life-long bond.  Your life force will be linked with mine and you’ll gain my lifespan.  However, when I die, you’ll also die but the reverse isn’t true.  Do you understand?”

Processing what she told him, the thought of her dying before him didn’t seem like something he’d have to concern himself with.  “So for me, this is a ‘until Death do us part’ sort of deal.”

Once again, oversimplifying the matter without being wrong on a base level, Mio blushed at the words of union usually reserved for marriage ceremonies.  “Is he really that oblivious?  Well, if he’s going to embarrass me like that…”  Not willing to let this sense of defeat stand, she set him back on the table and pressed her bare crotch down on the surface of it.  Her warm, moist lady bits squished out from her weight and parting her vulvas with a couple fingers, she giggled mischievously at the charismatic man.  “In that case, I suppose a kiss can seal the deal.”  With deft finger dexterity, she revealed her engorged love button.

“Wh-What!?”  Taken aback, Yushia was about to question her actions, but when he saw the determination on her face, he stopped himself.  “Mio-san isn’t the type of girl to do this sort of thing for the fun of it.  This must be a mandatory part of the ceremony.”  Swallowing his pride, he approached her vaginal and gently cupped her lady nub with his hands.  It was basically the size of his head!  “Besides, I’ve already crawled in her vagina.  This should be tame by comparison.”

However, for the Tiny Raising Club President, she couldn’t believe she made him do something so embarrassing.  “No.  I need to establish a contract quickly.”  Before losing the chance she created, Mio willed a pact to manifest between her and him and felt the minuscule amount of magical power and life force he carried be added to her own.  “It’s done, Yushia.”  Pulling her sex away, leaving behind a small puddle of sweet, thick nectar in it’s place, she placed a hand over her heart.  “Now he’s mine.  Sorry Megumi, but I’m not going to give him back to you.”

“So… I’m your familiar now?  I don’t feel much different.”  Not realizing the significance of his action, Yushia was inspecting his body, looking for some sort of change.

“That’s to be expected.  If you tiny body tried to hold even a little bit of my magical power right now, you’d probably explode.  For now I’m converting a portion of my magic to match what I got from you until you acclimate to it.”  Seeing the shocked expression that passed quickly on his face from that news made her giggle, and as much as she wanted to continue playing with him, she had just reminded herself of something else she needed to do.  Turning around and presenting her butt to him again, she looked back over her shoulder at him.  “There are other benefits we can go over later, but for now I’d like to go rescue Megumi before it’s too late.  You can play with my butt along the way, if you want.”

Spellbound by the perfection that was Mio’s backside, Yushia was already sure he had made the right choice in giving up being a Hero.  “I don’t know what help I could be otherwise.  But if you need me, Mio-sama, I am at your command.”  Winking up to her, he approached her juicy rear and began climbing it again.  While he was a bit nervous to go near her butthole again, he trusted her since she’d be aware of him this time.

Her face hidden from view by her gargantuan booty, he heard her chant a spell and felt a rush of magic infuse into his body.  “Don’t worry Yushia, this time I’ll make sure you can enjoy yourself.”  While he didn’t feel all that different, as the gentle aroma of her skin began to be replaced with the pungent odor of her backdoor, he didn’t have a reason to distrust her.

“It’s so big…  I bet she could easily swallow me with it.”  Reaching his destination, the increased warmth radiating from the girl’s anus comforted him as the globes of butt flesh gently closed in around him.  He was entirely encased in a Demon girl’s butt, yet he felt oddly at peace… and safe.  “Thank you, Mio-san… No, Mio-sama.”

Carefully letting her butt cheeks go as she stood up, the silver haired girl revelled in the presence clinging to her puffy anus like a security blanket.  “He called me ‘Mio-sama’...”  Giddy as a school girl, she pulled up her panties so she could go attempt to save the blonde Goddess her sister took, but as the undergarment slipped between her soft glutes, she felt the material press her familiar tightly against her butthole.  However, rather than tighten up, her tacky orifice relaxed just enough for the force to allow her new familiar to slip right in without any issue.  “Huh!?  Ehhhhh!”  Looking back at her butt, she could clearly feel Yushia on the inside of her body now.  “Yu-Yushia?!”

Inside Mio’s Butthole

While it happened too fast to prevent, the blonde man also didn’t fight as his Mistress’ backdoor slurped him up like a piece of candy and deposited him at the tail end of her digestive tract.  The smell was far more intense on the inside than the outside as to be expected, and thanks to a light spell he could see her colon just ahead was packed with fecal waste.  “Geez, this is just like when Megumi had me crawl in her butt after eating that drugged cake…  Actually, no, Mio-sama’s is more potent than Megumi’s was… but in a good way?”  He wasn’t afraid, hesitant, nervous or disgusted at all as sheets of slimy mucus rolled down the slick walls and pooled around his feet, and not even the skeletons and partially digested bones poking out of her waste concerned him.  “Unlike Megumi, she has to punish criminals almost daily.”  While he tried to block out the sight of the remains of Tinies she had picked up while they walked around the school, Yushia knew that Megumi had to have been lying when she told him she let them go.  If anything, Megumi acted more like a Demon whenever she consumed a Big Potion than Mio did, except she always used the excuse that she was a ‘Goddess’ and delivered ‘Divine Punishment’.

“Yushia?  Yushia, are you alright?  I didn’t mean to do that.”  Contacting him through telepathy, Mio worriedly tried to explain herself.

Chuckling, the blonde man sat down and leaned back against her colon wall.  “It’s fine.  In fact, it’s more than fine.  It’s pretty comfortable in here.”

He could feel the sigh of relief through her body, which was quickly followed by a light-hearted giggle.  “Well, it’s good that you’re making yourself comfortable. I think it’d be safer for you to stay where you are while I go track down where Mao went anyway.”

“If you think that’s best, my Mio-sama.  If you need me for anything, just let me know.”

“Maybe I should tell him I usually make Tinies that enter my butt eat my waste?”  Fixing her skirt, she wiggled her hips a bit.  “Though they’re usually the criminals that are doing ‘community service’.”  Giggling just remembering how effective that form of punishment usually worked, she headed for the door.

Mao’s Vault

Sneaking into her big sister’s office and taking the elevator to her underground facility, Mio looked around until she found the vault where the ‘Sacred Treasure’ was being kept.  “The gate’s open…  It looks like I was too late…”

All of the security disabled she was able to just walk right into the small room, the only thing inside being a black podium with a small puddle of white liquid leaking off a corner.  However, just below that unidentified ooze, she saw a red stain on the podium and the remains of a blonde haired girl in the school’s uniform crushed flat.

“Wait… I-Is that…?  No!  Megumi!”  While unrecognizable, it wouldn’t make sense for the Demon Lord to grab and shrink another student and bring them all the way to her secret vault just to kill them like this.  “I didn’t expect Mao to keep her promise and not hurt her…”  Tears welling up in her eyes, she carefully peeled the former Goddess’ body off the podium and brought her up to her mouth.  “…  I’m so sorry.  I didn’t want you to die, especially not like this… but you can rest now.”

Swallowing the broken body, she didn’t want Megumi’s corpse to be desecrated and if only in a small way, she wanted to keep the Goddess with her Hero.  However, there was a taste permeating the blonde’s remains that was unlike anything she had ever eaten before.

“I guess you really WERE a Goddess.  You don’t taste like any Demon or Tiny I’ve eaten before.  You taste… divine.”  Rubbing her stomach both affectionately and oddly satisfied for a snack so small, she steeled her resolve to make it up to her.  “I’ll take care of Yushia in your place, I promise.”  She would have to tell him what happened to her, but now wasn’t the time.  “If Mao and the Sacred Treasure are gone, that must mean she’s gone to the Human Realm…  What’s she going to do?”  Worried about her sister’s intentions, her eyes focused on the puddle of white that was dripping slowly onto the floor.  “Huh?  What’s this stuff next to her?”

Poking it, Mio rubbed the bit that stuck to her finger a bit.  The smell coming from it was familiar, but she wasn’t sure where she remembered it from.  However, most interesting to her was the immense amount of power that she could sense from it.

“Wait…  Is this, SEMEN!?”  The smell causing her arousal to flare up a bit, she recognized the fluid as the same as the stuff she and plenty of other Demon’s who are experiencing their ‘Growing’ produce from their temporary penises.  “B-But… this power I sense… If I consumed it, I could probably face Mao myself…”  With almost no hesitation, she licked up the spooge on her fingers, but while tasty, she felt all the magical power evaporate and escape without absorbing it.  “Hmm… how am I supposed to…”  The power was in her grasp, but for some reason she couldn’t consume it with her mouth.  “‘Mouth’?”  Trailing her fingers from the soft lips down her body to her salivating lower ‘mouth’, it was all but begging her to have a taste.  “Well… semen is supposed to go in a vagina…”

Hesitant, she let a drop that was about to fall to the floor land on her finger and pulled down her panties a bit.  However, the thought of her sister being left unchecked and killing all the Tinies in the Human Realm gave her the push to insert the fluid into her folds.  Immediately she felt her body heat up and power flow into her!  Her reserves of magical power increased over a hundred fold, her senses sharpened to the point she was completely aware of each individual living in her uterus and was subsequently aware that the potency of her magical power had saturated them to the point of fainting.

“I’m sorry everyone…  I tried to keep it from happening, but I’m just too strong now.”  Without even trying, she was just aware that thoughts of her dominated their minds, service through faith, deed or food were the only thought on the evacuated Tinies’ unconscious minds.  “Well…  if this power DOES save more Tinies in the long run, I suppose this was a small price to pay.”  She could just consume the ones in her womb directly and they’d all be happy.

“Mio-sama?  Mio-sama, are you alright?”  Hearing Yushia’s voice in her head, she was happy that, as her bonded servant, he was protected from the mind breaking effects of being enveloped in her magic potency.  If anything, it would accelerate his acclimation to her Demonic power.  “Everything got real warm all of a sudden and I feel… tingly.”

Scooping up as much of the remaining semen that she could, Mio just smiled as she held it to her vagina.  “Don’t worry Yushia.  Everything is fine.  I think my sister finally made a mistake that I can use to get a leg up on her.  This power is from that.”  As her vagina absorbed more and more of the power in the cum, her confidence grew as well.  “That should make me at least my sister’s equal now.  If I hurry, I may not be too late.”

[Mio succeeded in thwarting the Demon Lord’s plan of using the Sacred Treasure, but was too late to stop her from sacrificing the millions of humans to charge it.  Using it herself, she sealed her sister, and her manipulative maid, away, but was not able to bring back the humans that had already perished.  With the help of the Tiny Raising Club, she made the Human Realm a protected zone that her members maintained and the remnants of the humans who survived were able to rebuild.

Yushia was remembered as the Hero he was meant to be and Megumi immortalized as the Goddess who gave her life for them.]

GAME OVER?
