Kyouka looked at Midoriya with her eyebrow raised, confused as to why Mei Hatsume littered his stripped body with wires and patches - with her usual grey tanktop straining to not snap under the weight of her abundantly large breasts.

"Do explain this, Midoriya." she motioned to the scene she just walked into at the Support Class Research warehouse.

The greenet squirmed in his chair, clearly embarrassed at his near nudity and took a deep breath. "Hatsume's breasts are bigger."

The Earphone Jack user could've sworn she heard wrong - her breasts got bigger? No shit! Sure, the girl already had tits that could rival Momo's or Midnight-sensei's?

"Yeah, I see that. How did they get bigger then?"

"Well…"

-Not Long Ago (Not Even An Hour Ago)-

Izuku felt Mei pressing her body against his for what felt like the millionth time, her hands rubbing against the costume fabric as she felt up his body, analyzing the muscle development he had received since the last time he was here.

Her fingers followed the pattern on the contours of each muscle as she looked up and down his slim toned body, taking every defining muscle and bit of fiber in his body into consideration for her next baby. She could make a better pair of gloves, or some emergency braces to keep his body parts in shape.

She remembered briefly reading Berserker, and how the protagonist's armor could keep his bones in place while he fought the demon things or whatever. A blueprint began forming in her head as she felt her arms move and her breasts bulged in size.

"Huh?"

Izuku kept his eyes closed, not wanting to see Mei feel up his body, but when her hands were replaced with what felt like pillows and she sounded confused, he had to open his eyelids to see what was going on.

And what he saw were pillows, or rather, her now even bigger breasts pressed against his hip, her yellow crosshair eyes looking at his green ones. He felt a need to scream as he continued to stare, his sight wandering around her body as she let go, resting on her knees as she slipped up her shirt and held up her large plush tits.

She looked back at him and to her newly grown boobies, her nipples now a bright pink and thick like a nozzle cap, easily able to act as a plug for her mouth - hell, she could drink from her nipples now, not that she couldn't before.

But now that was easier too.

Now her curiosity had been peaked in how her DDD breasts grew even larger. She didn't even know what size they were, only that they were making her squeal in pleasure every time she moved, eager to get more stimulation.

-Now-

"So she was feeling you up and then her breasts began growing bigger?" Kyouka deadpanned skeptically.

Izuku nodded as Mei looked at her tablet, trying to find a reason for her tit growth.

"And you have no possible reason for why this happened?" Midoriya nodded once again as she slapped the front of her face 'God he's dense.' "Well, what if her breasts grew larger because of her groping of your body?"

His eyes became dinner plates as Mei stared at Kyouka.

"So he possibly has another Quirk that can make my boobs bigger when I grab him?"

The purplette shrugged. "I guess. Not like we have another test subject."

The pinkette looked at Kyouka before grinning widely. "Nah, we got you."

Jirou did a double take at what the steampunk inventor just said. "M-me!?"

Mei nodded as Izuku's cheeks flushed like a Christmas tree. Kyouka's cheeks mimicked Midoriya's, the idea of being a guinea pig not being something she considered a good idea. Especially if the end resulted in her breasts becoming stupidly huge.

It has taken her forever to get use to her B-cups, and now she had a chance to make them as big as she wanted them! A once in a lifetime opportunity.

But then... how would others react? How would they think of her? Would her friends look down on her? Would they make her feel bad? Well, if they were truly her friends, then they'd be happy for her.

A dark truth entered the Earphone Jack user, her mind realizing what it just thought of. The truth behind those words and how it could affect others.

She really did need to step back on the dark poem reading on Reddit.

She walked forward and looked at Izuku. "How about you keep your possible Quirk a secret for now, yeah?"

He blinked at her as Jirou looked back at Mei. "So you were grabbing onto him like you usually do?"

Mei nodded as she started walking around, bouncing her boobies in her shirt. Kyouka sighed deeply and grabbed onto Midoriya. The teen let out a baby goat cry as she held onto him, pressing her small boobs against his nicely toned chest.

He bit his lower lip as she felt her body heat up, her chest covering more of his skin as she felt the heat go through her veins. She then felt her thighs and ass bloat like balloons filling with water and thickening like jello, her body becoming more and more plump than it was before.

She let go and looked at herself, realizing what her actions had brought upon her. She'd just changed her body to a very noticeable degree, and was definitely going to receive glances and looks that her other classmates were being given.

Just as she wanted... but what she didn't want was her classmates to find out - not yet.

And speak of the devil, the worst person to see here right now was coming down from his room - Minoru Mineta.

She then grabbed Midoriya and placed him behind the counter as she squatted down on the floor, silently giving him commands.

(Don't let him see me!) she yelled voicelessly, making him gulp as he watched Mineta come down the stairs.

"Hey Midoriya, have you seen Asui today? I hear she's getting a frog inspired outfit and I wanna see her in it."

The greenette looked down as he broke out into a nervous sweat "Uh, I don't kn-know where she is... and I don't think she'd like you peeping."

Minoru rolled his eyes as the conversation went on. She wasn't paying attention, Kyouka just wanted to get out of here, but she then felt a warmth in her body once more. She looked around and saw that she wasn't touching him, so then why was she feeling like a bitch in heat -

Oh god.

He was hard?!

Her body flushed red as she noticed Midoriya's throbbing member in his pants, the tent he created being quite a noticeable one to her.

Well, she was squatting on the floor in front of him, so seeing his dick wasn't completely outside the possibility. But she wasn't expecting the sheer size of it snaking down his leg and began salivating at the the possible taste, her body yearning for his touch once more.

He had given her this body, so maybe she could reward him with something that she could now give: A tit job.

She then decided to end the pervert conversation going on above her and she stood up, her shirt ripping in half as her exposed tits bouncing wildly.

Mineta didn't even last ten seconds before his nose exploded, knocking him out and sticking him on the wall nearby.

Izuku covered his eyes, not wanting to experience the same fate Mineta had to her impromptu flashing, but he felt his hands move as Kyouka looked into his eyes, her tongue licking her lips seductively as she grew closer.

"You did this to me, Green." she purred, her earjacks running down his body, dragging across his skin between the sensor patches. "Let me show you how I intend to thank you."

Mei stood in the background, smiling like an idiot. "So that's what this feeling is…" She jotted down some more notes as Kyouka looked at the pinkette

"Oh Hatsume~" Her voice calling for the dreadlocked. "Get over here; your body needs him right now, doesn't it?"

Hatsume looked at Kyouka, unsure if what she'd said was true. Shrugging, bouncing her boobs as she set down her notes and slowly walked over "Well, I can get some accurate documentation if I do this…" She stood next to Izuku as Kyouka dropped to the floor, undoing Izuku's pants.

He tried to hold them back but she continued on, and pulling down the rest of it to his ankles. His All Might boxers strained under the amount of stimulation his was receiving, and the now horny pinkette picked up on this.

"Awww, does your cock want to be freed?" She yanked his undergarments and out popped a 9-inch girthy cock ready for fucking. Kyouka licked her lips as her body compelled her to give this boy- no, man - a well deserved blow job for his services.

Kyouka opened her mouth as wide as she could, her tongue out as she anxiously took head of the member into her mouth, painfully slow as she tried to get the flavor coating her tongue. Her body instinctively pulled her forward, forcing the rest of his cock to crash into the back of her throat in less than a second.

Mei looked at her fellow colleague as she screamed - in pain, pleasure, or shock, she didn't know or care - and stood back up to make out with the feverishly red Midoriya, her plush lips being pressed against his, taking his worries away.

His arms began wrapping around her voluptuous waist as she pressed her large nipples against his chest, taking off her goggles to kiss him better. She wrapped her arms around his neck, lifted her right leg to climb over her both her colleagues, sitting on Kyouka's head, sealing her at the base of his cock as she began to gag.

"Thith... tadths sho gooouuudd~" she gargled as thick ropes of drool went down her face and onto the workshop floor. Mei wrapped her legs around his waist began grinding against Izuku, her pussy now nearly tripled in size, dripping her juices all over him and in Kyouka hair.

Izuku's hand then went for Mei's large tit, grasping it firmly as Hatsume moaned in happiness, his touch sending shots of pleasure throughout her newly changed body. He then felt the urge swell up as he began cumming in Kyouka's mouth, his instant pressure shocking her and making her lips let go and backing away, his dick juice spill all over her face and chest.

She paused, looking at Izuku, seemingly holding her up with only his fantastic dick, she licked her lips as her body was filled with an unexplainable ecstasy, his cum making her pussy buzz in excitement. She then dove right back in and started sucking on his balls, his cum filling them back up once more. She started stroking his cock with her earlobes as her tongue moved across his genitals with grace and lust.

The sudden movement had them fall to the floor and Mei fumbled over, but Kyouka grabbed her and pulled her to her side, both eagerly tending to Izuku, Mei licking the tip of his cock as Kyouka stroked it with care. Jirou then grabbed the back of Mei's head and rammed it to the base of Midoriya's dick, gagging sounds turning her on.

"A little payback from before. Come on now, Hatsume~ Make him cum, make him feel good." Jirou purred as Mei moved her tongue out of the way to better give Izuku the head he deserved.

Hatsume bobbed her head back and forth as Jirou moved Mei's pink dreads out of the way. She looked back at Izuku's unintentionaly ecstatic face as he watched two beautiful women give him a really sexy blowjob.

Kyouka then lightly nibbled Mei's ear, making the inventor become more flushed as Kyouka then reached in front of the plump girl and began to softly touch her pussy lips, caressing them as their breasts mashed together. "You like it?"

The hair on the back of Hatsume's neck went straight up as Jirou breathed into her ear, her hot breath sending euphoric shivers down her spine. Her breaths became labored as she continued giving Izuku head as Jirou went on with her teasing.

"You really like Izuku, don't you? I bet you've always like him, since the Sports Festival, haven't you?"

Mei didn't care to answer, but instead felt herself go faster in reply, making Izuku spray his cum down his throat, his seed feeling like hot grease as it pumped down into her stomach.

Her lips made a popping sound as Jirou allowed her fresh air, uninfested with pubic hairs and raw sexual energy. Mei's shirt had been completely torn by now and their ripped clothes laid all over the floor.

Izuku looked at the pile and rubbed the back of his head. "I...I think I can get you my spare hoodies if you clean up the rest of the mess here?" The young adults looked at each other before shrugging.

"Yeah, just go quickly." He nodded as he sped off into his room as Mei picked up the ripped clothes and Kyouka got paper towels for the cum all over the floor.

'Man, he never did satisfy my pussy…' Then she and Mei then felt a wave of warmth as they were both notified of Izuku's current boner.

He was still horny.
