“Now, you’re sure about this?” Rie asked, “I’m only concerned because it might be hard to move for a while until it wears off.”

 

Mina Ashido only grinned broadly, “It’ll be fine! I switched my work study to here thanks to Midnight Sensei, and I’ll be staying in this hotel room while I’m here, so it’s all good!” she said, giving the dark haired girl a thumbs up gesture.

 

“Alright, just don’t say I didn’t warn you, another reason I don’t use my Quirk with my ass is because it’s REALLY easy to knock stuff over without meaning to.” Rie told her.

 

They were on the fourth floor of the Busteez Hero Agency/Love Hotel in one of the larger suite style rooms. Mina had volunteered for a test program Midnight wanted to start. The whole comfort girl thing was doing well, and Nejire was often sent out on such trips from what Mina had heard. The program Mina had signed up for was a two week assignment, and to pull it off, her ass and tits needed to be WAY bigger than they were normally.

 

She thought Mineta was bad, but some heroes took the perv thing to new levels. The pink skinned girl began stripping off her regular hero costume and neatly played it inside a storage case. She really wanted to get one of those quickband things Midoriya and some of her other classmates used, but it seemed there was a hell of a waiting list to get one.

 

‘Oh well,’ she thought, ‘It’s not like the case is heavy, also it looks really cool inside!’

 

Once she’d stripped naked, Mina sat down by the small table inside the hotel room and reached inside a small paper bag, pulling out four neatly rolled bundles of fabric. The fabric shared the same pattern as her costume, a mix of purple and a pale green that was almost blue. She unfurled the first of the rolls, finding it to be an arm length fingerless glove for the left hand. She tugged it on slowly, marveling at the smooth feel of the fabric. It was made of a unique fabric that was made from some kind of base elemental material. When her acid came into contact with it, the acid was neutralized before it could damage the fibers. But the reaction was limited to the acid that came in contact with the material directly. The rest retained its corrosiveness.

 

The next roll was a thigh length sock with toed ends. She tugged that up her right leg and fitted all her toes into the little pockets made for them. Mina followed that with the other sock, and finally the remaining glove. The end result was a “costume” that left Mina’s entire torso exposed. Which was the entire point. Hatsume had been all too happy to make a pervy version of her hero costume.

 

Once she was ‘dressed’, Mina took a look at herself in the mirror, turning so she could take a look at her own ass. Every inch of her skin was a bubblegum pink thanks to her quirk, and her nipples were a slightly darker shade of pink, but they went well with her skin. Giving herself a loud spank, Mina grinned broadly at her reflection before turning to Rie.

 

“Okay girl, go for it!” she said excitedly.

 

“You got it!” said Rie as her butt and tits suddenly ballooned outwards. Mina would never admit it out loud, but she was jealous! It must be nice to be able to control the size of your tits like that. Rie had to have been beating the guys off with a stick thanks to that. Though she wondered sometimes, she never really saw Rie do much more than work the greeting desk and maybe a few dance numbers Mina herself choreographed for her. She had to like sex, otherwise she wouldn’t work here. It was something of a mystery to the pink skinned young woman. But Mina would never be crass enough to ask how many guys she blew a night here, somehow that felt rude.

 

Rie’s tits expanded out until they were both easily bigger than her entire body beforehand. It really did look like a big pair of balloons being inflated. The sight was like something out of an erotic manga. Along with her tits, Rie also expanded her ass, making an uncomfortable expression as her costume suddenly rode up the crack of her ass in a super wedgie! Thongs were one thing, they did that by design, but Mina HATED when her panties rode up her butt like that. Thongs had minimal material, so it was comfortable, but with something meant to cover your ass, it felt distinctly uncomfortable. Just so much material there.

 

The whole process took only a couple of seconds, Rie could do it instantly, but only for herself. For what she did next, she needed a bit more time as she moved over to stand behind Mina and placed a hand against her back.

 

“Transfer!”

 

“WAH!” Mina yelped, not at the sudden tingling sensation in her ass and chest, but at the way the sudden shift on her center of gravity knocked her down on all fours in an instant. Well, not exactly all fours, as Mina softly landed on her new ginormous tits! They were like big fleshy marshmallows that she bounced up and down on lightly.

 

“I did warn you.” Rie said, “This isn’t like the smaller ones I give you and the other girls every now and again. Momo and Itsuka so far are the only ones who’ve gone THIS big.”

 

“I remember,” Mina said with a grin, “Seeing them walk around with those was fun! I was jealous!”

 

Rie only smiled and shook her head slightly, “Alright, my job’s done, any idea who’s coming first?”

 

“Don’t know, don’t care!” Mina said plainly, “But at least I won’t be needing a ton of these!” she said as she flicked her left wrist, producing a small black square with a distinctive ring shape in the middle.

 

“Oh wow, that one of those new ones?” asked Rie at the sight of the condom.

 

“Carbon nanotube latex poly-something or other, yeah, you can fill one of these with an olympic swimming pool’s worth of water and it won’t burst.” said Mina, “I just opted for the IUD thingy.”

 

IUD, or intrauterine device, was a highly effective birth control method available to all the girls in Busteez. Unlike the old ones that were about the size of a 25 yen piece and had a chance of not working, these new ones were smaller than a 1 yen coin and had a 100% effective rate. For about six months give or take a week. The recipient would know when they stopped working as they were designed to remove themselves. The sensation was kinda gross, but it let the user know without a doubt it was time for a new implant

 

“Yeah, I got one of those too, I think nearly all the girls did except that one with the hair from your school.” Rie said.

 

Mina blinked, “Hmmm…Hair? Oh you mean Ibara? Yeah, I think she’s allergic or something.” she said as she moved to try and stand, but failed miserably. Her tits were so heavy she didn’t even know how Momo and Itsuka had even been able to move! That, and her ass also made it tricky to move correctly.

 

Rie nodded and stretched, arching herself backwards until there was a soft ‘pop’ from her lower back that made Mina wince.

 

“Doesn’t that hurt?” she asked the dark haired girl.

 

“No, not really, it actually helps make me feel looser.” said Rie as she bent herself forward next, “Well, I gotta get moving, I’m doing a patrol tonight.”

 

“Have fun, give a baddie a good smooshing for me!” Mina said cheerfully.

 

“You got it, later girl!” said Rie before she made a quiet exit, leaving Mina alone in the hotel room.

 

With a little effort, Mina was able to stand again and grabbed the TV remote, turning it on and setting it to a simple music channel. She then moved over to a double king sized bed and moved to lay down on her stomach on top of it. Well, she was more laying atop her tits than anything else. Mina hummed to herself with the music as she waved her ass from side to side, enjoying the way she felt the flesh wiggle and wobble with her movements.

 

Part of her wondered what guy would come in first. Knowing her luck, it’d be Mineta, but if he had the money, then it was fine. She looked up when a knock suddenly sounded at the door. Mina looked to the right of where she lay. All the rooms like the one she currently occupied had a door control on the nightstand by the bed that unlocked the door without her having to get up. Mina tapped the button and heard the lock unlatch before someone turned the knob.

 

“Hey, sorry if this is the wrong room, this weird card just said fourth… Holy hell Raccoon Eyes!” yelled Katsuki Bakugo as he walked in holding a small card similar to Midoriya’s, the only difference being it was a muddy gold color and was made of a sturdy, but disposable paper. His red colored eyes went wide at the sight of Mina’s naked body lying on top of the bed with her arms crossed over her gigantic tits and her wide ass in the air.

 

Mina blinked in surprise, “Bakugo? Never figured you’d be into something like this.”

 

“What the hell happened to you?” he asked, “Did Bazooka Tits do that?”

 

“Bazooka…? OH, Rie, yeah, she did, and you gotta stop with the mean nicknames. I never liked that Racoon Eyes thing, not since the sports festival!” she berated him.

 

“Yeah, whatever, what the hell is this all about?” he said, slapping the card onto the table and leaning back against the wall.

 

Mina was confused, “Hang on, you don’t know?” she asked him.

 

Bakugo shook his head, he was dressed in his usual costume, though his oversized gauntlets had been retracted into a quickband on his wrist. As well as those shoulder mounted missile launcher things. Right now it just looked like he was in some military fatigues with a black tank top on for the most part.

 

“Tch, no, Midnight just saw me walk in and handed me this dumb card and sent me up here without a word. Seriously, can you even move like that?” he asked.

 

“I can, a little.” said Mina, “But that’s the point, this is supposed to be for guys with fantasies about fucking a chick with a body like this.”

 

“Hmmph, stupid fantasy.” said Bakugo, “Guy’s gonna need to do most of the work.”

 

“So!? You say that like it’s a bad thing! I for one think a guy ought to put in a little effort after all! Why should the girl do all the work and the guy just lay back like a dumb doll!?” responded Mina, waving her fist at him angrily.

 

Bakugo smirked his borderline cruel smirk, “Yeah? Well you do realize that like that, you only just reverse the roles there, not much equality if you ask me.”

 

“Yeah, well I didn’t ask! Jeez!!!” Mina said, fuming as she turned her head away and stiffened her body defiantly. Her ass made a light clapping noise as she tense her ass muscles. She blinked and turned as well as she could to look at her ass, making the noise several more times and giggling. She hadn’t realized she could make her ass do that.

 

“Whatever.” said Bakugo.

 

“Why’d Midnight send you here then?” Mina asked after a moment.

 

He shrugged, “Got me, I just came here for some of that curry shit Deku’s mom makes and maybe watch a few shows on stage. Endeavor gave us a pass for some meals and the like after our shifts. Unlike Deku, I can appreciate the female body without blushing like some dumb kid.” he said while looking over at her.

 

“Awww, that’s ALMOST sweet!” she told him, “And Midoriya’s not that bad, he just has confidence issues, though god knows why.” said Mina.

In a hotel room across town, Izuku Midoriya walked out of a shower and began drying his naked body. Then, for no reason he suddenly just sneezed hard!

 

“WAAAHCHOOO!”

 

“Bless you.” came the voice of the woman currently occupying the room with him, “You catching a cold or something?” asked Cassie.

 

Wiping his nose with a washcloth, Izuku shook his head even though the buff blonde couldn’t see the gesture, “Nah, probably just someone talking about me.” he replied.

 

“Huh, oh right, that’s a thing here.” Cassie replied, “You good to go again or what?” she asked and he could almost HEAR her grinning.

 

“Hey, you’re the one who wanted to do that thing with the honey! Not my fault everything got so sticky…” he said as he began walking back out of the bathroom.

 

---

 

“So, Mirko wants a team-up with you?” Mina asked.

 

“Tch, technically yes, but she won’t phrase it like that. Not that I blame her. She just said she needed to borrow me for a spell. Something about needing a demolition’s expert.” said Bakugo as he remained leaning against the wall. “I never pictured her doing any kind of investigatory stuff. It’s a lot easier to just kick ass and take names.”

 

“Well, after her injuries, Rumi told us she did a lot of reflecting on her thoughts about sidekicks and the like,” Mina said, recalling one of her conversations with the rabbit eared woman, “Oh yeah, you see her new arm and leg, she said to recommended her to that American girl you guys met on I-island, Melissa or something right?”

 

“Melissa Shield, yeah, she’s more Deku’s friend than mine, I just remember she was good at making stuff like that. Deku mentioned she and Dreads made his suit. If she could do something like that, a decent limb shouldn’t be any trouble.” Bakugo told her.

 

“Dreads?” Mina echoed, blinking her eyes. It took her a second to make the connection. “Oh, Mei-chan! Hey, that’s a mean nickname, it makes her sound like a Villain Bakugo!”

 

“Whatever.” Bakugo said dismissively.

 

“That aside, you do know you’ve been chatting with a pretty, naked, girl for more than twenty minutes and you haven’t so much as laid a finger on me. “Even Midoriya was more bold than that.” Mina said with a sly expression. Mina giggled and kicked her feet in the air at the stiff expression that came over Bakugo’s face. She then patted the space on the bed next to her in a silent invitation to sit with her.

 

“Tch,” Bakugo clicked his tongue, “I thought we were just enjoying a conversation,” he said as he pulled away from the wall and walked over to her. Mina just hummed softly before rolling onto her side, letting him have a good full view of her naked body. She slowly rubbed her hand over the hip in the air as she made no attempt to hide that she was looking at his crotch. Midoriya was big, and that’s what she liked, but she had little clue as to the rest of the boys in her class. She’d blackmailed Kaminari to tell her about Bakugo’s junk since the boys had their own bath and he’d no doubt would have seen it at LEAST once. And as Bakugo touched the control on his wrist to remove his clothes via quickband, Mina licked her lips happily.

 

“Niiiiiice! No wonder you’re so confident!” she said with a grin at the half hard dick that already was past his knee! It was only about half as thick as Midoriya’s, but even that was easily as thick as her leg! Mina could feel her pussy heating up already as she watched Bakugo’s dick pulse and jounce slowly as it grew.

 

“Heh, don’t even try and lie, I’ve heard about you.” Bakugo said.

 

With an overly dramatic flourish in her voice, Mina said, “I apologize for nothing!” She then grinned at him as she shamelessly reached over to grab his dick, stroking it with one hand, “Besides, you pass, full marks, 100 points!” she told him. Though Midoriya’d be 120 on size alone, but Bakugo didn’t need to know that. She’d seen so many guys completely “deflate” when she made comparisons, it was a total mood killer.

 

“Oh yeah, you like ‘em big right!?” asked Bakugo as he climbed onto the bed with her, pushing his now fully erect dick in her face.

 

“MMMMMMMH, I LOVE ‘EM BIG, HARD, AND FULL OF HOT AND STICKY CUM!!!” she told him boldly, “Especially if they can make me squeal!” she added as she rubbed her face against the underside of his dick. The smell was so strong, a thick manly odor that only served to make her even wetter! Bakugo had said he just came from his work study at the Endeavor agency, and she could tell! He smelled sweaty and musky, just the way Mina loved!

 

“Ahhhhhn, sho thick…” she moaned, dragging her tongue along the side of his dick as she looked up at him with her gold on black eyes. She then began kissing the side of it softly, inhaling deeply through her nose as she did so.

 

“Size queen slut!” said Bakugo as he rolled Mina onto her back suddenly. He then straddled her stomach, sliding his dick between her giant and heavy tits. The sheer size of them easily enveloped his entire dick, but she could FEEL every inch of it between them. The sensitivity of her breasts went up in accordance to the size Rie had gifted to her. So when Bakugo began sliding his cock back and forth, fucking her cleavage, she couldn’t help but moan at the feel of it!

 

“Yeah, yeah, YEEEEEAH, I LOVE BIG DIIIICKS, BIG DICKS ARE THE BEEEEST!!!!” Mina moaned, her fists gripping the sheets of the bed as Bakugo grabbed her giant sized nipples and used them like hand holds as he slammed his cock between her tits again and again!

 

“Yeah, you like that, you little pink slut?” he asked her, slamming into her over and over. Her massive tits jiggled and wobbled from every impact as she felt the tip of his cock dragging against the ultra soft skin between her tits.

 

“HMMMMMMH! I LOVE IT, I FUCKING LOVE IT!!! A BIG HARD DICK IS USING MY TITS LIKE A PUSSY AND IT FEELS SO GOOOD!!!!” Mina screamed as her hips absently hummed in the air. Her pussy was drooling non-stop now, her clit so hard it almost hurt!

 

Bakugo smirked at her, “Not bad, these actually feel pretty nice! All smooth and soft, I can see why some guys might like this!” he told her as he gave her left tit a hard slap, making it jiggle even harder.

 

“HMMMMMMMMM!!!!” Mina moaned, she loved it when the guy was rough. So many guys like Midoriya were gentle. And while gentle was fine, rough could get her off more and faster!

 

“Hmmm, you like that?” asked Bakugo with a sadistic grin, “Then how about THIS!?” he asked, gripping both her nipples so tight his fingers sank deep into the stiff flesh. He then twisted them both towards the other roughly, making swirling patterns in her titflesh.

 

“HWEEEEEEEEEEEEEEEK!!!!!” Mina squealed, her pussy gushing hard as she came. She leaned her head back against the mattress and let out a long deep moan of pleasure.

 

“Hehe, so you do like to squeal!” said Bakugo as he twisted her nippes away from each other next, pumping his cock even faster now.

 

“YEAH, YEAH AAHAAHHH FUUUUCK, CUMMINGGGGGGH…!” Mina hissed through clenched teeth.

 

“Slutty skank, you’ve found the perfect hero job!” Bakugo told her as he pushed his cock deeper, his lower body becoming almost completely enveloped in her tits as the tip of his dick pushed up from between her tits. The smell of sweat was even stronger now, it seemed to cling to the insides of her nostrils as she took it in. It made her almost dizzy as she didn’t waste a second before opening her mouth and swallowing the top few inches!

 

“MMMMMMPH!!! AHHHHN! CAWK, CAWK, LUV BHIG CAWKS!!!! SHO TASHTY, WUV DISH TASHTE, WUV ID…!” she slurred, slathering her tongue all over his cock as she tried to get as much as she could into her mouth. Her lips made wet slurping and smacking sounds as Bakugo fucked her mouth and tits together. Her saliva thoroughly coated the top few inches of his cock as she heard him groan at the feel of it.

 

Above her Bakugo laughed like a villain as he fucked her mouth harder, pushing his body farther up between her tits, allowing her to swallow more of his cock down her throat. She didn’t even realize when they’d changed positions, Mina only suddenly found herself resting on top of her tits again. Bakugo kneeling in front of her with his cock pumping in and out of her mouth!

 

“HOOOGAH, AGUH, WEEHGU, GUH, GPPPH, GOO…” Mina gagged and choked in pleasure as she felt her throat bulging around his girth. “EEEYAAAH, EYAH, PHUCK MUH PHROAT… AGUH GUG, GUG… MOAR, HAWDERRRR… AHHH PHUUUUCK, CUMMINGH, CUMMINGGGH…!” she choked, her eyes appearing almost completely black as they rolled back in her head.

 

“Yeah, like this!? And THIS!? Annnnnd THIIIIS!?” Bakugo roars, grabbing hold of both her antennae-like horns and using them as handlebars. While he pumped his length back and forth.

 

Mina couldn’t reply, Mina couldn’t think, all she could do was cum as Bakugo found her weakest point! Her horns were crazy sensitive! Just a light touch on them was nearly enough to make her cum on the spot! When Nejire played with them, it took all her will not to moan or make a stupid face in class back when they first met the “Big Three”.

 

“HUUUGUH, AUEEEH, GRRPHLE, MEHGUH… ACK ACK GUUUH…” Mina gagged and moaned as her mind felt as though it were turning into so much mush. She distantly heard Bakugo hurling more degrading insults at her, but Mina couldn’t make them out as she came every time his cock pushed down into her stomach. She could feel long thick ropes of her own drool hanging off her chin as she moaned at length.

 

Then, just as suddenly as it all started, it stopped. Mina coughed hard and took in several sweet lungfuls of oxygen. Her jaw felt almost unhinged, but she could still move it easily as Bakugo moved around behind her and sandwiched his cock between the massive cheeks of her expanded ass.

 

“You know, from this angle, it actually looks pretty good!” he told her before spanking her ass with a loud popping sound as his palm let off a harmless explosion against her. It was more noise than anything, but it stung so good! Mina felt herself shivering as she clenched her buttcheeks around his cock tightly.

 

“Mmmmmh, do that again!” she told him.

 

“What, THIS!?” he asked, spanking her other asscheek with another mini-blast.

 

“MMMMMMMMMMMMH!!!! YEEEEAH, AGAIN, SPANK ME MORE!!! OH I’M SUCH A DIRTY SLUTTY WHOOOORE, I NEED TO BE PUNIIIISHED…!” Mina moaned.

 

“Hahaha, yeah, you are a whore!” Bakugo told her, “Getting off like some masochistic skank!” he said, smacking her ass with the front and back of one hand while gripping her hip with the other. He then began slamming his cock back and forth between her asscheeks.

 

Mina then triggered her quick, producing a very harmless, but slick acid between her glutes, making it incredibly easy for Bakugo’s cock to move back and forth. He groaned again at the sudden slickness and moved to grab both her hips with his hands. Her butt was now a cherry red, and the sting felt so good Mina felt like she was cumming just from the pain alone!

 

“MMMMMMH SO GOOOD, AHHHH, I CAN’T WAIT ANYMOOOORE, MY ASS, FUCK MY ASS, I WANNA FEEL THAT BIG HARD COCK STRETCHING OUT MY ASSHOOOOOLE!!!” Mina screamed. Bakugo only laughed before Mina felt him pulling back even further than before. Her eyes then went wide and crossed as he pushed his thick cock up her ass with ease!

 

“HWEEEEEEEEEEEE, YESSSS, MY ASSS, MY ASS IS SO FUUUULLLLL, FUCK! FUCK, FUCK, FUCK FUUUUUUUUCK, FUCK MY ASS!!! NO MERCY, POUND THAT BIG, FAT, HARD DICK INTO ME SO IT NEVER CLOSES RIGHT AGAAAAIN…!” Mina howled in ecstasy.

 

“WAHAHAHAHAHAHAHA, you’re one crazy slut, you know that!?” Bakugo said, spanking her with explosions again.

 

“CUMMINGGGGGH, I’M CUMMING IN MY ASSSSSSS, IT FEELS SO GOOD, MY ASSS!! MY ASS FEELS GOOOOOD, MORE… MOREMOREMOREMORE, FUCKFUCKFUCK, MAKE MY ASS CUM MORE YOU HOT HEADED PUUUUNK!!!!” screamed Mina.

 

Bakugo only laughed, ramrodding his cock in and out of her asshole with a lewd wet noise as he groaned in pleasure. He then bent down over her, reaching up to grab her chin and turn her head back towards him. He then shoved his tongue down her throat. Mina only moaned into the kiss as their tongue swirled together, their mixed drool running down her chin.

 

“AHHHHHH, HAAAHHHHH, AHHHHH, CUMMMMINGGGGH, SHO GUUD, CUMMING PHEELSH SHO GUUUD, WANNA CUM, WANNA CUM MOOOAR…!” she moaned back against his tongue.

 

Still swirling his tongue against hers, Bakugo grabbed her right horn again, gripping it tight and pushing his thumb into the part that curved near the tip. Mina’s mind blanked out again as she lost herself in pleasure, her entire body having one gigantic orgasm. Distantly, she felt a pulsating sensation in her asshole, and a feeling of fullness in her stomach that only got stronger.

 

Mina then felt herself laying flat on the bed, her ass sore and a bitter taste in her mouth. Her limbs felt like jell-o as she struggled to move. She managed to turn her head to the right and spotted Bakugo getting dressed again. All he had to do was tap his wrist and his costume wrapped itself around him.

 

“Hey, you’re finally awake. Never had a girl pass out on me before.” he said with a smug look.

 

“Never had a guy figure out my weak spot before!” she countered.

 

The two of them laughed as Bakugo turned to leave.

 

“Going already?” she asked.

 

“I came here to get dinner, remember. Thanks to you, I just burned as many calories as I might get out of it. It’s not easy moving between those milk sacs there.” he said, pointing to her tits. “I was sweating so much I had to watch it so I wouldn’t blast them off you.”

 

Mina gulped, she hadn’t considered that! And suddenly had a greater understanding of just how in control Bakugo was. “Well uh, thanks for that then, I rather like my tits thank you very much.” she said, “But you don’t need to go downstairs, just call room service, you know? There is a menu in the drawer of the nightstand.”

 

“No shit?” Bakugo asked.

 

“Well DUH! This is a Hotel you know, fuck, even public brothels have room service!” she said, sticking her tongue out at him.

 

“Sh… Shut up, Size Queen!” Bakugo said, and Mina grinned when she realized he honestly didn’t know he could do that.
