It had taken Katsuki a few months to get used to what his dick looked like now. It had taken even more for the total numbness in his legs to give way to distant, barely-there pressure even when he was being thrown around roughly.
The weight had been the first feeling he really hadn’t been able to deny when his nerves had started to heal. Heavy, full, a constant reminder. Something about it was secure in a weird, fucked-up way.
Who thought about their own dick that way? Katsuki did, apparently.
Right then it was getting hard to remember all the self-deprecating thoughts he’s had about his body.
Eijirou was on his knees, his palms braced on Katsuki’s thighs and his mouth closed around Katsuki’s cock. His hair had once been caught in an updo that Katsuki had since ruined with the way his hands spasmed every time he dared move his tongue like that. It made him feel like his entire body was made of raw, exposed nerves, and Eijirou was the only one who knew how to touch them.
The sensation had just been pressure at first, sure, but—
Months had passed since then. Katsuki had gotten so sensitive he didn’t know what to do with himself.
Eijirou was being mean. He looked up through his wet eyelashes, a picture of innocence as he choked on Katsuki’s cock.
He raked his nails up Katsuki’s inner thigh until he drew another whimper out of him.
Then he pulled away, a wet string of saliva connecting his red lips to Katsuki’s cock. It looked fucking obscene. “Stop holding back,” he murmured.
His voice was rough. Katsuki had done that to him.
He moaned, and sparks erupted around him as his legs threatened to give out.
Eijirou took Katsuki’s cock back into his mouth.
This time, when Katsuki’s hips twitched he let them. He could listen. Be good for him.
Katsuki built up a clumsy rhythm, fucking into Eijirou’s mouth with short movements. Humping against his face, almost.
When Eijirou wrapped a hand around the base of his cock, Katsuki moaned out loud. His hips lifted off the bed, the pleasure so much it felt blinding. “Wait, Ei—”
Eijirou pulled away. He looked up again, with a hand wrapped around Katsuki’s cock. “Yeah?”
“Can we still—”
Eijirou’s demeanour changed immediately. The challenge on his face vanished, replaced by something soft as he kissed Katsuki’s inner thigh.
“You sure you wanna do this?” Eijirou’s eyes were filled with nothing but open warmth. “I can top, you know I don’t mind.”
“What, you think I can’t handle it?”
“Just offering.”
It’d be so easy to take the out, but—“I wanna know.”
“Okay.” Eijirou smiled and pulled Katsuki in for a kiss that lingered, filling his body with hot tension and melting down all of his uncertainty.
Katsuki held himself up on his forearms, looking down at Eijirou’s flushed face.
He was so fucking beautiful like this. He took on an almost ethereal glow when they made love—because Katsuki couldn’t really call it anything else. They got rough, and often, in fact Katsuki’s neck and chest were littered with shark-teethed bite marks most days, but he never felt as vulnerable as he did when he was touching Eijirou.
It hurt, being as in love as he was. It was inconvenient, too. Faced with the reality of Eijirou’s spread-open legs and flushed inner thighs, all the research Katsuki had done faded into nothing.
“Ei—”
“Stop frowning at your dick like that.” Eijirou chuckled. “C’mon, don’t you wanna feel how wet I am?”
Katsuki made a frustrated sound, sparkles popping around him. “Do you ever shut up?”
He wrapped a hand around his cock and tried to guide it into Eijirou.
He missed, but slick smeared down his shaft all the way down to his palm. Katsuki shivered. “Fuck, you’re soaking.”
“You don’t know how hot you are right now. Look at you, sweetheart.”
This was not the time for Katsuki’s mind to go fuzzy from the praise.
He must’ve taken too long calming down, because Eijirou took Katsuki’s cock in his hand and moved it himself until the head popped inside. They both groaned at the feeling. Katsuki kept pushing in slowly, watching Eijirou’s face for any sign of discomfort.
There were none. He’d flushed all the way down his chest, and his eyes were lidded.
“Look at us, baby.” Eijirou spread open his folds, rubbing two fingers around his own dick. “Watch me stretch around you.”
Katsuki grit his teeth. One of his palms sparked against Eijirou’s hardened collarbone.
His boyfriend chuckled. “Are you seriously—”
“Shut up.”
“C’mon, Katsuki, don’t tell me you can’t last now.”
Katsuki scowled and bit down on Eijirou’s shoulder, quick and mean, just to warn him. It drew a gasping breath out of him.
“ ‘s okay, baby,” Eijirou said. His voice only wavered the slightest bit. “I’m flattered.”
Katsuki would’ve retorted with something else, something even more biting, but—
There was something about it that just fit. He had to slow down so the warm, wet heat of his boyfriend didn’t overwhelm him. He was like one of those guys people joked about after one-night-stands, and he couldn’t help smiling against Eijirou’s shoulder.
He felt whole.
He pulled back and looked into his boyfriend’s eyes, still glimmering with amusement. Resting his forehead against Eijirou’s, he let himself laugh.
His eyes closed. For a moment, he just felt, the tension in his body dissolving into little exhales of air against Eijirou’s skin.
A light, warm weight against his nose let him know that Eijirou had kissed him there.
“Sap.”
“Guilty as charged.” There was a smile in his voice.
Katsuki rolled his hips, drawing a sharp gasp out of him. Good. It was about time someone fucked the attitude out of Eijirou.
He rocked in and out experimentally.
It felt good. Wet, warm. The world narrowed down to their point of connection, and Katsuki had to fight his Quirk from going off again.
His hip flexors were well developed, at least. He stretched all the time, and he never neglected any of his muscled groups when he exercised.
He buried his head in Eijirou’s shoulder, inhaling his soft earthy scent as he built up to what he considered a fast enough rhythm.
He pulled away, only to find Eijirou frowning at him like he’d done something wrong.
Katsuki thrusted harder, faster, as much as he could, and—Eijirou hardened his fingers around his hips, stopping his movement entirely.
“Anything wrong?” Katsuki asked. Am I not fucking you well enough?
Eijirou hesitated for a heartbeat. “Can I move your hips, baby?”
Something in Katsuki, already on edge, grew pliant at the nickname. He let himself be manhandled until his hips were angled upward ever so slightly. If he had any less dignity, he would’ve said thank you.
“Start more slowly,” Eijirou said in a low tone. “Make me feel all of it.”
He listened well. He let his cock drag through Eijirou, lingering where it made his eyes go hazier. He found out quickly that if he was slow and maintained a rhythm, it drove Eijirou wild while keeping Katsuki from coming first like a loser.
Eijirou made a needy, impatient sound in the back of his throat.
Like a well-trained dog, Katsuki slowed down and looked at him for guidance.
“Can you—” He moaned as Katsuki’s cock rubbed against his G-spot. “Can you touch me, baby? I can do it, but I think—”
“No,” Katsuki immediately said, cutting him off.
He needed to be the one to do it.
He needed to see Eijirou fall apart and know it was entirely because of him.
He spread the moisture and wrapped two fingers around Eijirou’s cock. It was harder than it looked to keep the same rhythm on both movements, but Katsuki wasn’t the fucking best for nothing. Plus, his body automatically repeated whatever he did that got Eijirou to groan and tighten around him.
“Right there, Katsuki, please—” He threw his head back, his eyes screwed shut.
He sped up his movements. Short and punched, focused on that one spot. “Fuck,” he groaned. “You’re so good to me, can’t believe I get to do this—”
“K-Katsuki—”
“I love you.”
“Oh, fuck—oh, baby, you’re gonna make me cum—” Eijirou’s hole tightened around him so hard Katsuki was the one to moan first, against his neck. That must’ve been too much for him, because he came with a deep, loud groan, getting wetter around Katsuki’s cock, fluttering around it wildly.
He’d already taken so much tonight, and that was what broke him.
He buried himself to the hilt and bit down on Eijirou’s neck as he came so hard tears blurred his vision. It felt a lot like it had when he’d just had his bottom growth, but deeper, more right. It pulsed through him, synchronizing with Eijirou’s and milking him until the tears actually fell. They left dark stains on their bedsheets.
Katsuki couldn’t have cared less.
He collapsed on his back and pulled Eijirou against his chest, letting his head rest on his pecs.
Katsuki bent his dick downward and held it, just enough to get it soft again through the saline pump. When it was, he looked down again.
Eijirou looked fucked out. His red hair fanned out underneath him, stuck to his forehead in messy wet strands. The flush that had travelled down his chest was blotchy now, and he looked like his limbs were made of lead.
“Thank you,” he whispered.
“You have nothing to thank me for.” He smiled, tired as he was. A single white tooth peeked past his lips. “You did so well.”
It was Katsuki’s turn to take care of him. Like Eijirou had done so many times.
He put him down gently, then he got up, went to the bathroom, and soaked a washcloth in warm water.
