Chapter Text
Izuku woke at the dinner table, his mom cooking in the kitchen. The smell wafting through the air was smoky and sweet. It was a smell he recognized but couldn’t place ...
“Mom, what are you cooking?”
“Your favorite, Izuku!”
“Pork Cutlet Bowl?!” He was grinning ear to ear.
“Take a look.” She set the bowl in front of Izuku and for some reason there was so much smoke billowing from the bowl he couldn’t see what was in it.
“What...is it?”
“Izuku what kind of question is that for you to ask your mother?” Inko walked around the table and rested her hand on the back of Izuku’s head.
“It’s just that...I-I can’t see it?” Izuku scrunched his eyes and moved closer to the bowl.
“Aw sweetie, just look closer.” Inko’s grip turned iron and she was pushing Izuku’s face closer and closer to the bowl until he was only centimeters away. He was pushing back but somehow she was so strong. Izuku couldn’t seem to wriggle out of her grasp.
“Mom! What-?!” And then his protests were muffled.
It was solid? But warm and he couldn’t breathe...he was suffocating! Mom, why? Please...someone...
Izuku’s eyes snapped open. He couldn’t see, everything was dark. He couldn’t breathe. Something was in his face, blocking is nose and his mouth. He pulled away from the obstruction and greedily gulped in air until his lungs burned.
He was hot and sticky with sweat. The room was dark and he still couldn’t see but at least he could breathe now. What a strange dream. Why was his room so hot? Gosh he was so sweaty and gross. He sat up trying to take in his surroundings and his muscles screamed in protest. Why was he so sore?! He moved to swing his leg off the side of the bed and froze. He wasn’t just sticky with sweat. He was just sticky...and naked! It felt like someone poured elmer’s glue between his legs. What on....OH MY GO-!!
All at once, last night came back to him. Kacchan and he-Izuku, him, they did-OH FRICK! He nearly tripped out of bed running to the bathroom. He ran hot water over a towel and proceeded to wipe himself off, freaking out at every swipe. It was so sticky and crusty and and and....KACCHAN CAME INSIDE OF HIM.
Izuku felt faint.
He wobbled out of the bathroom and blindly made his way across the bedroom. He needed to find his clothes. He tripped over something, was it a shirt? Crap, crap, crap, crap!
“Quiet down...so damn noisy...” Came a disembodied yet familiar voice from the bed.
“Eh?” Izuku’s response came out in a pitch that only dogs could hear.
An exasperated sigh was the only sound in the room and Izuku moved towards it looking for something to orient himself. His hands were out in front of himself reaching for something, anything to hold on to.
A hand wrapped around his wrist and suddenly Izuku was airborne. He landed on the bed a skipped heartbeat later,soft sheets against his back.
“Wha-!!”
Katsuki’s arm wrapped around Izuku’s shoulders and pulled him forcefully into his side. Izuku’s face was pressed against Katsuki’s pec and he realized how he been suffocated into waking up.
Izuku was in bed with Kacchan. Laying next to Kacchan!
“Shhhh...go back to sleep. It’s too damn early.” Katsuki grumbled, clearly not finding one iota of this situation unusual.
Izuku rested his head on Katsuki’s chest, desperately trying to calm his heart threatening to beat out of his chest. He inhaled, the smell of smoke and brown sugar filling his lungs and exhaled slowly. At least that’s where that smell came from, Izuku thought absently.
It’s was no good, he couldn’t relax!
Izuku laid awake on Kacchan’s firm chest trying to lull himself to sleep but all he could do was obsess over every little detail he could remember from last night.
He-He lost his virginity...to Kacchan...He lost his virginity...and now he was in bed, very naked, next to that very same someone who was also very naked! He needed time to process this, time to think. What does this all mean? What does this make him and Kacchan? He couldn’t handle this. He couldn’t do this. Izuku started getting up, he had to go. He needed to think.
Katsuki’s iron grip around his shoulders didn’t relent.
“Deku.”
A cold shiver ran down Izuku’s spine. The body under him shifted. He could barely see the outline of the spiky blonde hair and even though he couldn’t see the red eyes, he could feel them on his face.
“K-Kacchan?” He squeaked in surprise.
“You got this much energy left even though I split you in half?” Katsuki growled.
Izuku shuddered, red creeping over his face at the memory.
“N-No...I-I just...We did...”
Katsuki grabbed his ass so rough Izuku felt the bruises blooming in real time.
“What, you wanna instant replay?”
“Wha-Kacchan-!”
Katsuki’s hand reached around and fingered Izuku’s hole and he blew out a breath of irritated air through his nose.
“Ah, I forgot to tell you, you gotta clean this out of you...” He swirled his finger around in the still sloppy opening.
“K-Kacchan!” Izuku’s entire body was on fire and he was getting hard. He felt so overly sensitive.
“You getting hard from me just playing with your ass?” Katsuki laughed, low and predatorial. “You want it again Deku?”
He ground his erection into Izuku’s stomach so there was no confusion as to what “it” was.
“...m’not...” He replied feebly, rubbing his erection on Kacchan’s leg. Katsuki chuckled gruffly in response. He grabbed Izuku by his hips.
“Come here.”
He moved to a sitting position and pulled Izuku into his lap. Izuku buried his face in Katsuki’s shoulder to hide his embarrassment even though in this dim light, no one would see the deep red blush that had replaced all of his freckles. Katsuki brought his hand back to Izuku’s bottom, continuing his previous ministrations. His other hand wrapped around Izuku’s weeping erection, pumping slowly, drawing out lewd sounds in the otherwise quiet room. Izuku found himself whimpering deliciously and bucking his hips into Kacchan’s hand despite himself.
“K-Kaccha-n”
Forming complete words or thoughts was too difficult a task for Izuku in his current situation.
Katsuki moved the hand on Izuku’s erection to his own.
“Here Deku, spread your legs for me.”
Izuku gasped as he moved over Kacchan’s pulsing erection, already pointed at his hole, impatiently eager to be inside him. He sank slowly, savoring each inch that passed through his barrier.
“Ah!” Izuku gasped at feeling incredibly full as he finally seated himself, Kacchan fully inside him. Izuku was shaking with the pleasure and stimulation he was feeling.
“Hah? Feel good, Deku? You like my fat dick inside you?”
The only response he could muster was a half nod.
“Put your hands on my shoulders.” Izuku did as he was told. “I want you to move yourself, make yourself feel good while you ride me.”
Izuku let out a small gasp as those words seemed impossibly arouse him further. He rocked back and forth experimentally feeling his insides shifting. Katsuki let out a sigh and dropped his head back, his hands still gripping Izuku’s hips.
“Mm yeah...so good...”
Izuku found himself blushing furiously at the praise and he wanted to make Kacchan feel even better. He ground his hips down and in clockwise circles and Kacchan sucked in a breath. Ooo, Izuku liked that reaction. He did it again, this time angling himself more and when he leaned back, a spark shot through his body.
“Ah!”
“Mmh, that’s your prostate. Lean back and you’ll hit it.” Kacchan was breathing heavily, eyes lidded.
Izuku leaned back and felt it again. He arched back further, resting his hands on Kacchan’s thighs and rocked himself onto his cock, hitting his prostate over and over again.
“Oh fuck, yeah, that’s it...shit, your body is amazing.”
Katsuki grabbed Izuku’s cock and pumped it in time with his movements. Izuku was feeling so good, how was it possible to feel this good? He felt his orgasm building, he ground his hips harder and faster chasing the release of the pressure.
“M’gon...un...gonna!”
Izuku came so hard, he saw white. He was vaguely aware that his eyes had rolled back and that he’d almost cum on his own face but at this moment he was a cloud of pure satisfaction. He was still twitching and coming down from his post orgasmic high when Katsuki pushed him back on the sheets. Izuku found his legs on either side of his torso splaying him wide open and then the feeling of Kacchan sinking deep inside him until he bottomed out.
Izuku’s eyelashes fluttered.
Katsuki began his steady pace of pulling almost all the way out then snapping all the way back in. It was torture to Izuku’s overstimulated body. He felt spent but the more Kacchan thrust into him, the more he began to feel his arousal come back until Katsuki was slamming into him and Izuku was hard and leaking on his own chest, the precum mixing with his previous release.
“Fuck.” Slam. “Deku.” Thrust. “Feel so...” Slam. “Damn good!” Thrust.
Izuku was beginning to lose himself in the pleasure. He grabbed his cock and jerked himself quickly as Kacchan began to lose his pace and slammed into him with abandon.
“Gonna-!”
Katsuki came with a roar, igniting small blasts across Izuku’s legs. He felt the burns on the back of his thighs and the overwhelming stimulation put him over the edge. Izuku came hard once again, streams landing on his chest.
Both were panting heavily and a bit more than sweaty. Katsuki pulled out of Izuku who whined at the sudden emptiness.
“I’m gonna grab a towel. Be right back.”
Katsuki returned with a wet towel and cleaned them both off, taking care to wipe the back of Izuku’s legs softly where he’d accidentally burned him. After rubbing some of the cellular serum on Izuku’s legs, they collapsed back into bed once more. Izuku lay on Kacchan’s chest only this time he felt content and completely spent.
“Kacchan?”
“Hm?”
“I’ve been curious about this for a while now but...what does my skin feel like to you?”
He hummed thoughtfully, stroking Izuku’s back. “It’s like a rabbit’s but not fur. Like velvet or something? I dunno, it’s hard to describe.”
“Oh.” Izuku wasn’t sure what he had expected but...like a rabbit?
“Do you think it’s because of a chemical reaction with your skin? Because of your explosive sweat? Or do you think my skin feels this way to everyone?”
“Dunno.”
“Maybe I should test it out...”
Thoughts of everyone touching all over Deku came immediately unbidden to Katsuki’s mind.
“No.”
“No? Why not?”
“Cause then they’ll wanna do things to you.” Katsuki grumbled.
“Like you did?”
“Tsk, that’s different.”
Izuku lifted his head off Kacchan’s chest to look him in the eye.
“Why?”
Katsuki rolled his eyes. “Ugh, because shitty Deku. I’m not into guys.” He poked Izuku’s forehead in enunciation.
Izuku’s face scrunched up in confusion. “Kacchan...you know I’m a guy right?”
“Pfft barely.” He smirked.
“Rude.”
“Anyway, unlike you, I’m not usually into this kind of thing.”
Izuku’s eyes widened. “Kacchan,” his face was completely serious. “I’m not gay.”
Katsuki’s jaw would have hit the mattress had his chest not been there to catch it.
“Wait a fucking minute-“ Izuku put his hand over Katsuki’s mouth before he could finish whatever he was going to say. He shifted nervously.
“I-it’s different...cause it’s you...”
Izuku slowly removed his hands, worried that he may have said too much. Katsuki threw a hand over his face and groaned. He was grumbling under his breath and Izuku couldn’t really make out what he was saying other than “stupid fucking Deku” so he waited expectantly, unsure of what else to do after dropping such a sappy truth bomb.
“Kacchan?”
“Shut up.” Katsuki pulled Izuku onto his chest is a tight hug, pinning him to his torso so he couldn’t see Kacchan’s face.
“Me too you shitty nerd. He growled softly.
Izuku snuggled in, feeling a bubble of joy well up through his body. He felt giddy and light-headed and drifted off with the smell of burnt sugar clinging to his skin.
