Ashido walked up to the door to Izuku's apartment just as his mother was leaving.
"Oh, hello there," Inko greeted, "Here to see Izuku?"
She nodded, "A bunch of us from class 1A planned to have a day out together, here to bring him to the others."
"How nice. I'm just leaving, he'll be out of the bathroom. Feel free to wait for him inside." Izuku's mother said before heading off.
Ashido thanked her before heading into the apartment. Ashido let herself into Izuku's room, intending to spend her time waiting by amusing herself joking at the sheer quantity of All Might merch his room contained.
When she did, she found that his computer had been left open. She grinned mischievously to herself as she approached the computer, curiosity overtaking her. At Izuku's computer she found that several pages had been bookmarked.
Hoping to find something embarrassing she could joke at him with, she began opening the pages. Her eyes opened at what she found.
What she found was smut. Plain and simple. And quite a lot of it. Pictures, videos, hentai, stories; you name it. At first it was just some vanilla hetero stuff, mostly hero themed which surprised Mina about as much the sun rising in the morning. But as she opened more, she found more scandalous stuff.
Hardcore femdom, dick girls and futanari pounding cute looking boys, a mountain of foot fetish content. Mina's jaw dropped at everything she was seeing, her panties growing uncomfortably tight as she began growing stiff from what she was seeing.
"It's always, always the quiet ones.." Mina muttered to herself, unconsciously rubbing her bulge as she looked over the various pages.
She tensed at hearing the bathroom door open, and swiftly closed every window she'd opened.
She spun the chair around, crossing one leg over the other and crossing her arms; posing herself to make it seem as though all her attention had been on waiting for Izuku in said boss pose, the computer disregarded.
"M-Mina!" Izuku tensed at seeing her in his room, blushing as he glanced around at all the All Might merchandise.
Mina rolled her eyes, "Oh come on, its just cute." She assured him, though couldn't help but snicker at realizing that that only seemed to embarrass her more.
"Anyway," Mina said as Izuku sat on his bed, "My feet are killing me after all the walking, think a cutie like you could help me?" She asked with her usual grin.
"H-help you how?" Izuku questioned, looking up to try and hide his having glanced to her feet.
"How do you think?" She said. Her voice was right on the edge between casual and sultry, just enough to make Izuku freeze up, the beginnings of a tent starting to form as he tried desperately to figure out what she meant; but still normal sounding enough that Mina could claim full innocence.
Giggling to herself, Mina removed her shoes, placing her sock covered feet in Izuku's lap; pretending not to feel the growing stiffness as she said, "A foot massage of course. If you don't mind I mean." She said with a smile, pretending to be none the wiser to his secret kinks. Izuku began sputtering at this.
Mina couldn't have begun to guess what exactly he said exactly, but managed to figure he was claiming something to the effect of worrying it'd be wrong for him to be touching a girl like that.
Mina rolled her eyes, feigning annoyance, "Come on Izuku, nothing wrong with giving me an innocent foot rub~" She said.
Izuku bit the inside of his cheek, and Mina could see him thinking so hard the air would likely have started smelling like burnt rubber and melting metal had it gone on much longer.
"O-okay." Izuku finally said, beginning to gently rub Mina's feet through her socks.
Mina pulled her feet back-a mix of equal parts relief and disappointment on his face until he realized she was simply removing her socks, leaving her pink feet fully and telling him to, "Really get in there." She placed her feet back, Mina fully able to feel how hard he'd gotten; though maintained her oblivious expression as Izuku began to rub her feet.
Mina purred happily at the feeling of the foot rub. It felt good, better than she'd been expecting; then again maybe she should have guessed that he'd have gotten good at them.
Izuku gulped as silently as possible as he felt Mina's soft foot rubbing against his tent. Believing it to be unintentional, just her idly moving her feet without realizing she was doing so against a, he assumed, hidden hard-on.
Mina kept teasing him for a few minutes before starting to grind the sole of her foot down too obviously to be by accident. "Did you get this hard just from rubbing my feet~?" She questioned with a smirk. Izuku's mind seemed to short circuit.
"I-you-wha-I-n-n-no I would never I-I didn't I-" The words, or in some cases just the syllables, spilled out of him like a burst pipe until Ashido stopped him.
"It's okay Deku, I don't mind~" She purred, foot grinding down against him even harder, sending shivers of pleasure through his entire body.
"I saw all those naughty little secrets on your computer. I can't believe how kinky you are under that shy outer shell~"
"N-no, I'm.. I don't-" Izuku was cut off by Mina pouncing suddenly from the chair, smashing her lips against his own as she pinned him beneath her against the bed.
She held the kiss for several moments before pulling away, "I told you Izuku, it's okay," Mina said, "Cause guess what? I'm kinky to~" She giggled at his cute, shocked expression.
"I thought you were hot from the first day I saw you you know," Mina said, grinding her own stiff tent against Izuku's to inform him exactly what she was under that skirt, "That body of yours really helps of course." Mina moved down, stripping Izuku's pants and underwear.
She whistled, admiring his stiff eight inches. "Not bad~" She purred, licking along it teasingly, tongue swirling around her tip before her head lowered down, taking in his length.
Izuku moaned, gripping the bed as Mina's head bobbed, sucking as she steadily took one inch after another. But she wasn't content with just this, wanting to tease him more as well.
Happily, she was more than flexible enough to pull off her next move, back bending to arch her legs over Izuku's body; her cute pink toes wiggling in front of Izuku's face as she continued to suck his throbbing rod.
She giggled, able to feel his cock twitch as he began sucking on her toes desperately. She shivered at the feeling herself, enjoying the control she had over the situation, how Izuku was too desperate for more to even try stopping her despite how innocent and shy he usually was.
Poor thing didn't last long enough despite her being certain he probably could normally. Mina swallowed his release as he gave it, slowly moving her body back and lifting her head.
"You've got an impressive cock, but I'd suggest eating more fruit," Mina suggested, "Helps the taste of what you give out." Izuku's blush-potentially permanently staining his cheeks at this point-grew deeper at this.
Mina moved back, removing her skirt and underwear to free her member. Her thick, eleven inches sprung up throbbing with need.
"I helped you with yours, now you've gotta help me~" She purred.
Izuku stared at her rod with a mix of desire and nervousness.
Mina giggled, "Don't worry, I'll be gentle...ish." Izuku practically whimpered at this, a sound that nearly made her pounce him right there.
She managed to hold herself back, having him remove the rest of his clothes as she did the same before he moved onto his fours for her. She crawled onto the bed, her fingers growing damp with a fluid. She was so glad she'd learned how to control not only the viscosity of her acid but also the strength of it.
Rather than strengthening them, she put both as the weakest they could reach; essentially coating her finger in the perfect anal lubricant. She pushed her fingers inside, spreading the lube while also loosening Izuku's tight hole; her other hand spreading the same lube along her cock.
When she was ready she brought her tip to Izuku's puckered hole, "Get ready~" Mina warned him before pushing in.
True to her word, Mina held herself back and took it slow at first, working her member in deeper but going slowly as she began to fuck him. It didn't last forever mind you, the sound of Izuku's moans too much for her.
Her hips slowly started to pick up speed, throbbing inside of Izuku as she stretched his tight, formerly virgin hole more and more, forcing herself in deeper.
"S-so fucking good~" Mina moaned, hips starting to smack against his ass as she buried herself in fully. Izuku cried out, his own member throbbing as well; having grown stiff again while being fingered.
Mina could tell, and leaned over Izuku's body, sucking on his neck as she continued to pound into the boy, grunting as the bed shook from the force of it. When she could tell that neither of them were going to last much longer, she changed their position.
Izuku yelped as Mina flipped him over onto his back, lifting his legs up over her shoulders as she hammered into him harder, drilling him in a mating press. He cried out, throbbing as he got even closer.
Mina reached for her discarded socks, pressing one against Izuku's face and pulling the other down onto his stiffness, stroking him with it.
Izuku groaned as he inhaled, taking in the scent of Mina's feet. It was too much for him. He shook as he unloaded into the sock, soaking it through with his cum and spurting onto Mina's chest.
Mina groaned, shaking as she felt Izuku's walls squeezing so tight around him, like she was being milked. She couldn't hold out any longer, letting loose into him.
They both collapsed to the bed, panting heavily. They laid together, Izuku holding onto Mina. She hadn't pegged him to be a cuddler but wasn't shocked by it in the slightest.
"The others can wait," Mina said, "We need to get cleaned up."
As she got up to take a shower, she grinned to herself, excited to share their little secret with the girls.
