It was late. The dorms of U.A. High were quiet, save for the hum of refrigerators and the occasional distant snore. In his room, Izuku Midoriya, better known as Deku, was hunched over his desk, scribbling in one of his many notebooks. He was analyzing the footage from the day's training exercise, muttering to himself about kinetic force redistribution and the optimal angle of recoil for a Detroit Smash.
His phone, lying face up on the desk, suddenly lit up with a notification. The sender made him blink. It was Mina Ashido.
Mina: hey deku 🤘
Deku stared at the message, his analytical mind temporarily short-circuiting. Mina was friendly with everyone, but they didn't text one-on-one often. He fumbled with the phone, his thumbs hovering over the screen.
Deku: Oh, hi Ashido-san! Is everything okay? It's pretty late.
Mina: yep everythings greattt 😄 listen random question
Deku's heart rate ticked up. Random questions from Mina Ashido at 11 PM could go in any direction.
Mina: u busy tonight?
Deku: Not really? Just finishing up some notes on today's training. Why?
He watched the three little dots appear, disappear, then appear again. Whatever she was typing, it required serious consideration.
Mina: u wanna come fuck this pussy tonight?
Izuku dropped his phone. It clattered on the desk, sliding perilously close to the edge. He snatched it back, his eyes wide as he read the message again. And a third time. His face went from pale to crimson in about half a second. He was sure he was having a stroke. This had to be a mistake. A typo. Maybe she meant to ask if he wanted to come pet her cat, but her autocorrect was possessed by a demon?
Deku: I... what? Ashido-san, I think there might be a misunderstanding.
Mina: no misunderstanding 😘 i wont tell anyone, it'll be our secret
Deku: OUR SECRET?! A secret about what?! Are you in danger? Is this code? Is "pussy" the name of a new villain you've discovered and you need back-up?
Mina: lmaooooo no deku ur so cute. it's not code. i'm asking if u wanna come to my room and have sex. with me.
Izuku felt his soul leave his body. He was floating above his desk, looking down at a noodle-armed, green-haired boy having a complete system shutdown. Mina Ashido. The bubbly, confident, gorgeous acid-user. Was asking him, gangly, nerdy, overthinking Deku, to come to her room for... for that.
Deku: Why me?! Not that I'm complaining! I'm just! Very surprised! Is this a prank from Kaminari?
Mina: omg it's not a prank lol. ur just sweet. and strong. and i've been curious. so? u in or out?
Deku: ...In.
The moment he hit send, he wanted to throw his phone out the window. What was he doing?! This was insane. This was against so many rules. But... it was Mina. And she was asking him. And a very loud, very primal part of his brain that usually only got to come out during a fight was screaming "YES, YOU IDIOT, YES!"
Mina: awesome 😈 door's unlocked. just come on in when u get here.
Izuku stood up, paced his room three times, changed his shirt twice (deciding on his All Might t-shirt, because of course he did), and crept out into the silent hallway. Every creak of the floorboards sounded like an explosion. He felt like a spy, but with way more anxiety and a much less clear objective.
He reached Mina's door on the 2nd floor. It was slightly ajar, just as she'd said. He took a deep, shuddering breath, his hand trembling as he pushed it open.
Mina's room was a chaotic explosion of pink and personality. Posters of rock bands, makeup scattered across her dresser, and a faint, sweet smell that was uniquely hers. And there she was, sitting on her bed, propped up on a pile of pillows. She was wearing an oversized band t-shirt and shorts, and she gave him a wide, genuine smile that didn't seem the least bit awkward.
"Hey," she said, her voice soft. "You actually came."
"I... uh... yeah," Deku managed, closing the door behind him. "Your text was... direct."
"Why beat around the bush?" Mina giggled, patting the space on the bed next to her. "C'mon. Don't be all the way over there."
He shuffled over, sitting stiffly on the very edge of the mattress. "So... how does this...?"
"This?" Mina leaned in, her pink hair brushing against his cheek. She smelled like strawberries and something vaguely chemical. "This is easy. We just... have fun. No strings, no weirdness tomorrow. Just us, tonight." Her hand rested on his thigh, and Izuku felt a jolt go through him that was more powerful than a full-power One For All flick.
He turned to face her, and all the nervous energy suddenly found a new direction. He leaned in and kissed her. It was clumsy at first, all teeth and nervous pressure, but Mina just laughed softly against his lips and guided him, her hands moving up to tangle in his hair.
Clothes disappeared in a flurry of fumbling movements. Deku's brain was still trying to catch up, but his body knew exactly what to do. He was overwhelmed by her—the softness of her skin, the confident way she touched him, the sight of her lying back against her pillows, her pink skin flushed with excitement.
"Okay, big guy," she breathed, pulling him down on top of her. "Let's see what you've got."
He entered her, and the sensation was so intense, so completely new, that he saw stars. It was nothing like anything he'd ever imagined. It was warm and tight and perfect. Mina let out a happy little sigh, wrapping her legs around his waist.
"Ooooh, hello there," she murmured, rocking her hips against his. "See? That's not so scary, is it?"
Deku couldn't form words. He just started to move, his instincts taking over completely. The analytical part of his brain was finally silenced, replaced by pure, unadulterated feeling. He looked down at her, at the blissed-out expression on her face, and something inside him snapped.
He felt it building—the familiar, overwhelming pressure of One For All, but this time it wasn't in his fist. It was... somewhere else. A coiling, tightening heat that was demanding release.
"Mina," he grunted, his voice strained. "I... I think I'm gonna..."
"Yeah, baby, me too," she gasped, digging her nails into his back. "Let it go. Cum for me."
And he did.
It wasn't a normal release. It was a detonation.
Years of repressed hormonal energy, combined with the raw power of his Quirk that he was still learning to control, all erupted at once. It was a tidal wave, a flash flood, a biblical-level event. He felt it pour out of him in a powerful, seemingly endless surge.
Mina's eyes, which had been closed in ecstasy, suddenly shot wide open.
"Whoa—!" she yelped, her entire body jolting. "Deku! Holy—!"
He collapsed against her, panting, his ears ringing. For a moment, he thought he'd hurt her. He struggled to push himself up, his arms shaking. "I'm so sorry! Are you okay? I tried to warn you, I couldn't—"
He stopped when he looked at her face.
She wasn't in pain. She was... staring down between them with an expression of pure, unadulterated awe.
"Deku..." she said slowly, a huge grin spreading across her face. She reached down with one finger and poked her own lower stomach. "Dude. I think you... I think you filled my entire uterus."
Izuku's face, which had just returned to a normal color, immediately flushed beet red again. "I what?!"
"There is so much," she continued, laughing now. It was a bright, beautiful, genuinely delighted laugh. "I've been with guys before, but this is... this is next-level. This is a pro-level ejaculation. Is this a side effect of your Quirk? Like, a Super Cum Smash?"
"I don't think it's called that!" he squeaked, covering his face with his hands. "I'm so sorry, I didn't know it would be... like that."
"Sorry?!" Mina grabbed his hands and pulled them away from his face, her grin impossibly wide. "Deku, this is the greatest night of my life. This is amazing! We have to do this again. Like, a lot. Can we do this again tomorrow?"
He just stared at her, completely baffled by her reaction. She was thrilled. Genuinely, over-the-moon thrilled about the... volume.
"I... yeah?" he managed.
"Yes!" she cheered, pulling him down for a sloppy, triumphant kiss. "You're officially my favorite. Now, you gotta stay for a bit. We have to bask in the afterglow. And also, I'm pretty sure I'm going to be leaking for a week, and I want to enjoy it."
Deku just lay there, utterly bewildered, as Mina Ashido, the Rapper Hero: Pinky, giggled and cuddled up to him, thoroughly impressed with his unexpected, powerful, and very messy secret.
