“So, Blasty,” Kaminari started. “Your heat’s in two weeks.”
“And what if it is? Shut the fuck up!”
He seemed annoyed. He always did when they talked about heats, even when he did it with Eijirou alone.
Too bad Kaminari didn’t seem to get the hint. “Who’s the lucky Alpha, then?”
“Hah?”
“You’re not spending it alone, are you? I know you’re kinda bratty, but half of the Alphas in school would still say yes if you asked!”
Eijirou sank his teeth into his lower lip to keep himself from growling. He controlled his strawberry scent as much as he could, but it was still getting amber-dark. He would’ve thought his Omega would calm down with the possessiveness after two years. No such luck, apparently.
“Why the fuck would I want that?” Bakugou yelled. He stood up straighter on Eijirou’s bed to look down at Kaminari.
“...because it helps with your heat? It doesn’t have to be serious, you know.”
“Maybe it helps you , moron.” Bakugou’s tone was dismissive.
“C’mon, we’re all Omegas here, you can admit it.”
“Is it so hard to imagine I don’t wanna be fucked by a damn knothead?” Bakugou’s face was flushed with anger. “They smell so damn bad I wanna shower every time I talk to one! I have no idea what you weirdos are always going on about!”
“Well, it’s mostly the knotting and biting—” Kaminari had to cut himself off when Bakugou launched himself across the bed, his hands sparking in warning.
Eijirou liked to think he could read Bakugou pretty well, and right now he was too upset for all of it to be embarrassment. If Bakugou had secretly wanted to be ravaged by an Alpha, he would’ve been blushing at least. He’d still be attacking Kaminari, definitely, but it would’ve been different.
Something in Eijirou recognized something in Bakugou, something tired and vulnerable.
“Kami, stop it!”
“He’s gonna kill me if I do!” Kaminari yelled, trying to hide behind Eijirou’s punching bag.
Eijirou reached out and grabbed Bkaugou’s wrist, dragging him down next to him on his bed. Bakugou went easily, and they sat down side by side, their backs leaning against the side of Eijirou’s nest. Slowly, he ran his wrist over Bakugou’s.
The mix of caramel and strawberries washed over him, making his Omega whine in his head. Bakugou looked much happier. There was even a ghost of a smile on his face, until he saw Eijirou was watching him and he started frowning.
“How come you guys never scent me like that?” Kaminari complained, and for just one second Eijirou understood the urge to explode his face.
“I can scent you,” he said.
When he tried to get off the bed, Bakugou hissed and pulled him closer. “No the fuck you can’t.”
Kaminari shrugged. “Too soon after the fight, I guess?”
“You never get to scent him like that.”
If Eijirou didn’t know better, he’d say Bakugou smelled possessive.
He could feel his own scent turn all pleased and wanting , so he took his wrist off Bakugou’s. It was one thing for him to be able to tell Eijirou wanted him, and another entirely to get scented with it.
Kaminari gave them a strange look. “Okay, well, I guess that’s my cue to leave. Have fun talking about Alphas or whatever you guys do when you’re alone!” As he was about to close the door, he turned around again. “Oh, and let me know if you need my notes or something for your heat.”
Bakugou hissed again. It’d be cute if he wasn’t actually capable of killing Kaminari right there. Their friend seemed to agree and hurried out.
“We never talk about Alphas when we’re alone,” Bakugou said, his voice still angry.
“No,” Eijirou agreed.
He didn’t know what to say. Should he ruin everything and tell Bakugou why he didn’t? He’d thought Bakugou would understand, earlier, but what if that was just wishful thinking on Eijirou’s part? What if he thought he couldn’t be friends with someone like that ?
“Wanna come into my nest?” he said instead. All of his friends were allowed inside, but Bakugou was the one who actually did it the most often. The soft walls carried a faded caramel scent more often than not.
Bakugou agreed wordlessly. The annoyance faded from his demeanour when they got in, even more so when Eijirou scented his wrist again. They were squished against each other, almost cuddling but not quite.
“You don’t want an Alpha to help with your heat.” Eijirou hesitated. He took a leap of faith. “What about someone else?”
Bakugou snorted. “What, Shitty Hair, you offering?”
He didn’t answer that, he couldn’t , but Bakugou understood all the same. He froze, snatching his hand away.
No. That was why Eijirou hadn’t said anything before. He had to do something to fix it. “I’m so sorry—”
“Are you looking down on me? Think I can’t do it by myself? Fuck you, I don’t need anyone!” He pushed himself away, not getting very far in the nest.
He was getting closed up. If Eijirou didn’t do something about it, this would damage their friendship way more than any heat share ever could.
“No, no, I didn’t mean it like that!” Eijirou’s cheeks heated up. “It’s stupid. It’s not that I think you need someone, I just wanted to do that. For you. With you. You don’t have to say anything, I know it’s dumb—”
Bakugou considered for a second, then he smirked. His scent turned into something sweeter, mind-numbingly good, and he slid closer to Eijirou again.
“Think you can handle me?” He practically purred the words.
“I know I can,” Eijirou said. He didn’t, but he really, really wanted to, and had to count for something. “Besides, Omegas come more with other Omegas than with Alphas or Betas.”
“Any reason you know that off the top of your head?” Bakugou looked amused.
“I think you know why.”
It felt like too much, too raw to say out loud, but—Bakugou had basically agreed to heat share with Eijirou, hadn’t he? It wasn’t like he had room to judge. Glass houses and all that.
“I would’ve thought you prefer Alphas, with your whole manliness thing.” His tone was casual, but the sweetness of his scent had started to spoil, into possessiveness and something sad. Eijirou had smelled that on Bakugou before, and he’d never known what it had meant. He would’ve never dared hope that it had meant this. He wanted to go back in time and slap himself.
He cupped Bakugou’s face in his hands. “Dude, you’re the manliest person I know!”
“That a confession?”
“I don’t know, is it?” He smiled. He’d take as much teasing as Bakugou wanted if that meant his scent would stay the pleased, warm caramel it was now.
Bakugou’s eyes drifted to his lips, bashful, lightning-fast.
Eijirou couldn’t have stopped himself if he wanted to.
It started out slow, filled with words they’d held back and words they couldn’t say yet, at seventeen and during their first kiss.
You’re it for me .
I’ll never feel this for anyone else.
I love you.
It was soft and romantic for a little bit.
Then Eijirou’s need swelled to bursting, so he slotted their lips together better, tilting Bakugou’s head with his hands. The gesture was surprisingly dominant. For a second he was scared that Bakugou would hate him for it.
He didn’t. He let himself be led into a firmer kiss, soft like putty in Eijirou’s hands.
His scent was so, so sweet. Eijirou could practically taste the arousal, and it was making him want to do more. Anything to get more of that scent on him, on his nest, in his room.
Reluctantly, he pulled his lips from Bakugou’s, closing his mouth over the pheromone-soaked gland at the base of his Omega’s neck. He made a small, aborted sound, arching into Eijirou’s touch. The sweet taste was making Eijirou dizzy with desire.
Bakugou was panting, his breath warm over Eijirou’s scent gland. When he latched on and sucked harshly, like he was taking revenge, Eijirou couldn’t hold back a moan.
Fuck, he wanted to be bitten so badly. He didn’t care if the bite held. Bakugou’s teeth scratched over the sensitive skin, and he thought deliriously that it would be better if it didn’t hold. Then Bakugou would have no choice but to do it over and over and over again.
“Your scent—” A shiver raked through Bakugou. “I’m wet all the time around you. I don’t know what’s wrong with me.”
“Nothing’s wrong with you, baby.” Eijirou pulled him into a kiss. He could taste his own strawberry scent on his lips, and wasn’t that enough to make him crumble. “You’re perfect.”
Bakugou whined, pulling at Eijirou’s shoulder with blunt fingernails.
He was so sweet. So pliant.
Eijirou slid a thigh between his legs and Bakugou didn’t hesitate to grind against it. He was slicking so much that Eijirou could feel his own thigh getting wet through the thin material of his sweatpants.
He’d never be able to wash those things.
It smelled so good in the room, like two of them combined and so much arousal he could mistake it for pre-heat. He tucked his face into Bakugou’s neck and sucked another mark, reveling in the way his body molded to Eijirou’s.
He understood. There was no space between them and it still felt like too much.
He pulled back to admire his handiwork. Bakugou’s neck was pale, flushed pink with arousal and littered with blooming purple and red marks. His chest was heaving over every breath. “You’re beautiful,” Eijirou said. Bakugou’s hips faltered, his head throwing back on a moan. “So sensitive. I didn’t think it’s take this little to make you this desperate.”
“Fuck off.”
“I didn’t mean it in a bad way. I like it.” Eijirou sucked another mark into his neck to punctuate his sentence.
“L-Like you aren’t just as fucking wet.” He was trying to act like he had the upper hand. Cute.
“This isn’t about me, baby.”
The whine that earned him was beautiful.
Bakugou was right. Slick was dripping down Ejirou’s thighs, soaking his clothes and his nest, but he couldn’t care less. He wanted to see how much he could make his Omega lose it.
He slid a hand into the elastic of his sweatpants, stroking over his lower belly until Bakugou made an impatient noise, then cupped his pussy.
Oh, fuck.
He was so wet. Eijirou could smell the sweet caramel more strongly, and he felt like he’d taken three straight shots of liquor. The urge to make him feel good was overwhelming.
Eijirou reached down and slicked his fingers, then he started rubbing circles around Bakugou’s clit slowly. God, he was so fucking wet. And his reactions— when Eijirou pressed down harder, Bakugou arched his back so tightly he lifted off the bed.
He maintained the rhythm, whispering sweet nothings into Bakugou’s ear— you’re doing so well, so pretty for me, my Omega —
His fangs hurt with the need to claim.
Something primal inside Eijirou was pushing at him, telling him to sink them into that pretty, already-marked skin, and he was shaking with the effort to hold back. Especially with how Bakugou reacted at the tiniest scrape of his teeth.
“Please, I can’t, feels so fucking good— oh god, they’re so sharp—”
He got wetter, too, slick dripping down Eijirou’s palm . It was like he wanted to make sure Eijirou wouldn’t sleep a single night without wanting to fuck him into his nest.
He moved his hand, using his thumb over Bakugou’s clit as he dipped his fingers lower. “Can I?” he tried not to show how desperate he was for it.
“Fuck, please—”
He was so warm inside Eijirou almost hardened his finger by accident.
“So big—”
“Baby, it’s one finger.” He’d meant it as teasing, but Eijirou could hear the roughness in his own voice.
Bakugou didn’t respond, moaning against his neck as Eijirou started pumping his finger in and out. He wet his thumb, rubbed it over his clit again, and that was all it took.
Bakugou looked surprised, taken aback by the pleasure. He bit down on his lower lip as he got wetter, his cunt clenching around Eijirou’s finger.
“You’re so beautiful when you come,” he couldn’t help but whisper.
Bakugou moaned again, shuddering weakly against Eijirou’s chest with the aftershocks.
It took them a moment to recover, before Bakugou got dressed and pushed himself out of the nest. They’d had sleepovers, but he tended to prefer sleeping in his own nest, especially since Kamino.
It would’ve hurt if he hadn’t looked so happy when he leaned down to give Eijirou a goodnight kiss.
“We’re courting now, dumbass. I’m going to bed,” Bakugou said. He took something off Eijirou’s chair and walked to the door, before Eijirou grabbed him by the arm to stop him.
“Wait! I—I should’ve gotten you a courting gift!”
Bakugou smirked. “How do you know I won’t get you one first?”
“I don’t care, I’ll get one anyway.”
“You’re ridiculous.” He huffed out an amused breath. “Goodnight, Eijirou.” He didn’t ask for permission. Why would he, when Eijirou was so painfully transparent with his devotion?
He knew something he hadn’t known yesterday, though: his mate was just as transparent, especially when he wasn’t guarding the affection in his scent.
“Goodnight, Katsuki.”
Katsuki showed up to class the next day in Eijirou’s uniform blazer, smelling like him. He wasn’t exactly showing off his hickies, but he wasn’t hiding them either. They were between classes now, and it was becoming clear people had noticed.
“Damn, Kacchan, you move fast.” Kaminari whistled jokingly. “You gonna tell us who it is?”
“I think it’s the Alpha chick from Support,” Sero said.
“They were talking a lot last week.”
They’d had a fucking costume to fix last week. Eijirou knew, because Katsuki had complained about how annoying her scent was.
Still, his blood boiled in his veins. He was so used to suppressing his instincts, most of all his possessive ones.
But after last night—he had a right to be possessive, didn’t he? And his instincts had helped him. Katsuki had never responded poorly to them.
He leaned in, letting his scent take on the dark edge of claiming, and rested his wrist against Katsuki’s scent gland. Rubbed it back and forth to mix their scents. Katsuki’s breath caught.
“Are you for real?” Sero said, his eyes wide.
Katsuki had leaned back against Eijirou’s chest, subtly pliant from the public claim, but he straightened at once. “Problem?”
“Nah, man, just didn’t see it coming.”
“Oh my god, I really should’ve.” Kaminari laughed. “You guys were always like that .”
Katsuki relaxed. “Looks like your dumbass streak is going strong.”
From behind Midoriya’s desk, Mineta laughed. “What happens when you guys need a real Alpha, though?” Under the weight of four glares, he wilted a little, but he continued. “What? I’m just saying what we’re all thinking.”
“None of us are thinking that, actually,” Kaminari said warily.
“Can we not pretend?” Mineta laughed. “I mean if they wanna do it sometimes, sure, but they’re gonna need real claims soon. I was just asking.”
The thought of some random Alpha marking Katsuki made Eijirou’s Omega frantic. His arms hardened on instinct, and he barely held himself back from attacking Mineta.
“He’s mine .” His voice wasn’t quite a growl, but it wasn’t far.
Eijirou’s scent curled around them, darker than fresh strawberries had any right to get. Katsuki’s hands burnt twin imprints into his desk.
Mineta’s scent darkened in return, the challenge unmistakeable. Eijirou hardened his hands, preparing for the inevitable challenge—
“Are we seriously gonna watch Kirishima kick that guy’s ass for fun?” Sero’s tone was judgemental.
“I was just about to say—”
“It’s so uneven I think it’s unfair to let it happen,” Jirou added.
The atmosphere had shifted. There wouldn’t be a fight anymore, Eijirou was sure of it.
Mineta backed away, retreating to a corner.
Eijirou almost couldn’t believe it. He’d been so in his head about competing with Alphas, about his scent being all sweet, about not being able to growl, that he’d missed the bigger picture. What his mate kept trying to tell him. He was a person in his own right, and he was strong enough. He ran his wrist over Katsuki’s scent gland, trying to convey his gratitude.
Katsuki stood up from his desk abruptly.
“You okay, Kacchan?” Kaminari asked.
“Don’t wanna see the Grape Fucker’s damn face.”
No one questioned him when he said that, all of them returning to whatever they were doing before they’d seen Katsuki’s marks.
Katsuki grabbed Eijirou’s tie, pulled him toward the nearest Omega bathroom, pushed open a stall, and only let go when the door was locked behind them.
“Hey, sorry—”
“Take some fuckin’ responsibility,” Katsuki hissed.
Now that they weren’t running anymore, Eijirou could actually smell him. He froze.
Katsuki smelled like he was dripping , and his pheromones were making it hard for Eijirou to say anything really.
So he didn’t. He dropped down to his knees in front of his mate, right there in the school bathroom.
“What’re you doing?”
“Exactly what you said.” Eijirou pulled Katsuki’s uniform pants down, meeting less than zero resistance. He cupped a hand over the hot, wet core of him. Katsuki gasped, then his right hand flew over his own mouth. “What did you mean then, baby?”
“You’re gonna get us caught, dumbass.” His voice was breathy.
“No, you’re gonna get us caught.” Eijirou pushed his boxers to the side and parted his folds with two fingers, gently. Katsuki was so wet that the slick webbed between them, making his mouth water. “Tell me you didn’t want this when you brought me here. What did you hope would happen? You’re so obvious.”
“I don’t—oh, fuck —”
He tasted just as sweet as he smelled. The slick coated Eijirou’s tongue, and Katsuki grabbed his hair roughly when he moaned into his pussy.
His mate had realized what was happening, too.
He wasn’t shy anymore. He knew all of it was just for his pleasure.
“There, right there, c’mon—” He pulled Eijirou’s hair again, bringing him right where he wanted him, and Eijirou whined at the slight sting of pain.
When he sucked his clit harder, Katsuki’s knees buckled, his hands sparking against the tile walls. Eijirou pulled him closer, let him ride his face until neither of them could breathe. Licked him through his orgasm, trying to keep his rhythm steady and not too hard.
“Thank you.” Eijirou kissed his inner thigh, looking into his red eyes to show how serious he was.
“Don't thank me .” Katsuki scoffed, but he was too breathless for it to seem annoyed. “Stop claiming in public like that if you don’t wanna deal with it.”
Everyone was going to be so sick of them, because Eijirou had just been given a cheat code to get exactly what he wanted.
He caught a glimpse of himself in the mirror while Katsuki was washing his face. He looked fucked out. His spikes were halfway undone, standing in whatever directions Katsuki had pulled them in. His lips were swollen, and he’d probably have to change his uniform. Both parts of it.
He was so fucking proud of himself.
They were cuddling in Eijirou’s nest later that evening, Katsuki tucked against his chest with his eyes hooded and relaxed.
Eijirou would forever blame being scent-drunk for what he blurted out next.
“Can I fuck you?”
Katsuki pulled away and looked him up and down with visible confusion. “Can you?”
“I—”
“I mean if that’s what you wanna call it, I don’t care.”
That was sweet of him. Eijirou smiled, almost took the out, but—now that he thought he could actually have what he wanted, he was getting selfish.
“No, I—you can say no.” He pulled away from the nest and opened the drawer under his bed. He pulled out the bright orange dildo and black harness he’d bought impulsively. He was blushing so hard he could feel the blood in his own cheeks. “I meant with this. If that’s something you want. I—I do.”
Katsuki looked more surprised than anything, at least.
“Why the fuck do you just own that?”
“I, um, I ordered it last year. So I could think I was fucking you when I was in heat. I don’t know, my Omega was just—” Eijirou faltered, embarrassed. That was undeniably creepy, unmanly behaviour from a friend. He had Katsuki’s permission now, but he didn't have it back then.
Katsuki’s scent, already sugary, turned even sweeter. He hooked his arms around Eijirou’s neck. “That’s what your Omega wanted?”
“Look, I know it’s weird—”
Katsuki cut him off with a chaste kiss. When he pulled away, he smirked. “Mine was worse. It wouldn’t get that I can’t just beg you to fuck me. I had a hoodie of yours and I think it got so wet I couldn’t even wash it off.”
So that was where that had gone? But more importantly—
Eijirou pulled him closer by his neck, holding his hand tightly around the nape. “You’re so hot I can’t believe you’re real.”
Katsuki’s eyes immediately glazed over, slipping into that soft, Omega-like space.
Their kiss wasn’t chaste. It couldn’t be, not with how pliable and willing Katsuki looked. Eijirou licked into his mouth like he was fucking him already, swallowing all the little whines and gasps he made.
They took off their clothes carelessly. Eijirou might’ve ripped a hole into his shirt. He literally could not have cared less.
He sucked a mark over Katsuki’s scent gland, lapping at the sweet pheromone fluid, and let his hands wonder over his mate’s body. Mapping his hips, his tiny waist, his soft lower belly, his arms. Resting over his jaw.
When Eijirou rolled one of his nipples in his fingers, Katsuki keened.
His body was full of these wonderful little buttons. A wave of possessiveness washed over Eijirou. It was a good thing Katsuki’d ended up with someone like him, who took pleasure in taking him apart.
He deserved that. He deserved the best, and Eijirou vowed to be it.
Eijirou let the tips of his fingers harden, pinching his mate’s nipples more firmly. They were flushed red, his entire chest a beautiful pink, and he ground against Eijirou’s thigh like he couldn’t even tell he was doing it.
When Eijirou sucked one of his nipples into his mouth hard , Katsuki’s entire body went rigid.
“Oh fuck, how—” he moaned, his back arching off the bed. “ Eijirou .”
“Did you just come from that, Katsuki?” He couldn’t keep the wonder out of his voice.
His mate was so sensitive .
They’ll never leave that damn bedroom. Eijirou would just spend all their time making him feel good.
Katsuki seemed embarrassed. “Fuck off, it was just—oh, fuck , c’mon—”
It was so easy to distract him, though. Eijirou sucked more marks into his neck, like it wasn’t half purple already.
He didn’t keep it up for long, though. He was on a mission, and nothing would stop him from watching Katsuki moan into his nest’s blankets from being fucked so hard.
Eijirou slipped his harness on almost absentmindedly, kissing Katsuki through it. When he realized what Eijirou was doing, he stilled.
“Why do you know how to use that so well?” Katsuki frowned, his hands sparking in warning.
For a second, Eijirou was just confused.
“Are you jealous ?”
“Isn’t that how being mates works, asshole? Wouldn’t you be jealous if I told you I learned how to fuck from all the other Omegas I railed?”
“I never said that—”
“Might as well have.”
Katsuki pulled something out of the nest blindly to cover himself—a hoodie of Eijirou’s, old and frayed— and draped it over his lap. His eyes were flickering widely between emotions.
Eijirou cupped his face in his hands. He must’ve looked ridiculous, with the harness on and all, but nothing mattered when his mate was doubting himself like that. “Katsuki, why’d I say I got that?”
“To help with your heat.”
“So how do you think I know how to use it?”
“...oh.”
His cheeks bloomed pink, and Eijirou had to kiss his forehead before he did anything else. That got him an offended slap over the arm. “Should’ve said that, asshole.”
“Or,” Eijirou said as he started kissing down his shoulder. “You could’ve asked instead of going all possessive on me.” He bit down, leaving an imprint of his shark-like teeth but not drawing blood. Katsuki shuddered. “But I guess that’s too much to ask when your Omega likes me this much.”
“Thought you wanted to fuck me. Quit yapping.” He couldn’t hide his blush, though.
“What’s the rush? I like making you moan.” He bit down again to prove his point. Katsuki was starting to look like he’d been mauled.
“ Clearly .”
“Didn’t hear you complain.”
“Are you gonna fuck me today or—oh, shit, Eijirou—” He closed his eyes as Eijirou cupped his pussy in his hand. “Please, just do something , fuck—”
Eijirou would’ve taken longer to tease him, to rub his clit until his moans grew higher-pitched and he came all over his hand, but he’d wanted this for so long.
He grabbed the dildo in his hand and aligned it, rubbing it against Katsuki’s pussy to make it wet. Maybe a little more, just because he could. Then he pulled his mate into a kiss as he sank inside.
Katsuki’s mouth grew slack against his, opened on a cut-off whine. He just didn’t close it. He didn’t look like he could .
He was just as beautiful as Eijirou had imagined in his heat-hazes.
His inner lips parted around the strap, his pussy stretched obscenely despite the girth not being that unusual.
Their slick mixed where it dripped down into Eijirou’s nest.
He grinded forward, slowly, in measured circles. Katsuki had grabbed his hair. His grip was starting to hurt just a little, but he didn’t mind.
Then he tilted his hips and thrusted again. Katsuki moaned out loud, his voice breaking over it. Little explosions sparked over Eijirou’s hair, and he managed to harden it just in time.
He’d never lived before, he was sure of it.
“You could’ve warned me, baby. What, does it feel too good?” He couldn’t keep the teasing out of his voice. “Didn’t know I could just make you shut up like that.”
“Your Quirk’s literally—”
He cut himself off when Eijirou fucked into him harder, angling his hips to hit the exact spot that had made him lose it in the first place.
Katsuki didn’t last, not with how Eijirou was rubbing that spot on every stroke, trying his very hardest to hear more of his mate’s sounds. The only warning was a choked up “I’m gonna—” and he tensed up, his pussy contracting so hard around the strap that Eijirou could see his abs flex.
His eyes were hazy and unfocused as Eijirou slowed down, keeping up a slow pace.
The contractions died out after a few minutes, but Katsuki’s expression remained open and blissed out. Gorgeous. Eijirou had to see more of it.
“Can you take more, baby?” he asked, quietly against Katsuki’s mouth. “I know you can. You’re doing so well.”
Katsuki couldn’t even speak. He moaned weakly, digging his fingers into Eijirou’s shoulders. They’d leave marks, at this rate. Eijirou really, really hoped they would.
He slid a finger inside, slowly, feeling Katsuki’s pussy stretch to make it fit. It was so warm inside, so fucking wet, that Eijirou could feel his own scent get darker.
He couldn’t help it.
“So good for me.” His voice was rough, so much so that it was obvious even to himself. He stroked his palm over Katsuki’s inner thigh and slipped another finger into that intoxicating velvety heat.
If Katsuki was loud before, he sounded desperate now. Like the pleasure was so much it actually hurt him.
“Eijirou— mate—” He tilted his head, silently begging. His scent gland was wet . It must’ve been painful, how much he needed it sucked clean and marked.
Eijirou couldn’t stand it anymore. He let the possessive part of his hindbrain win. He tilted Katsuki’s head to the side and bit down. He wasn’t gentle about it either. It felt so good to have his fangs sink into something that his rhythm faltered for a second.
There was blood trickling into his mouth, and it tasted like sweet caramel and heaven.
“Ei, please —” He tilted his head, pushing his flesh further into Eijirou’s sharp teeth.
Katsuki screamed when he came.
He tightened around Eijirou’s fingers, pulsing uncontrollably, slick pouring over them and getting them even wetter. Eijirou worked him through the orgasm, grinding directly into his g-spot.
Katsuki kept trying to say something, but it was coming out as garbled moans. Poor, sweet thing.
Eijirou only pulled out when he was sure his mate’s orgasm was over. First his fingers and then his strap. The sound they made was fucking obscene, making more blood rush into Eijirou’s face.
He licked over his fingers almost absentmindedly, cleaning the slick. Katsuki’s eyes followed him.
“Omega,” Katsuki said. He lifted a hand to his face. It was shaking. Eijirou kissed right over his open palm.
“What is it?”
“I didn’t know anything could feel that fucking good.” His eyes were wet. Tears of pleasure.
“Good thing you have me now,” Eijirou said. “You won’t have to put up with whatever you were getting by yourself.”
Katsuki whined, his scent already taking a submissive undertone. It felt like an injection of adrenaline straight into Eijirou’s veins. He’d made his mate feel that good. He had that much power over him.
He didn’t want it to stop.
Sex was supposed to end when the Alpha knotted the Omega, but—Eijirou wasn’t an Alpha. He hadn’t come yet and he honestly didn’t care.
He cupped Katsuki’s pretty face and used his thumb to wipe the corners of his eyes. It was kind of cute how he couldn’t control himself. Eijirou wanted to make it worse. “Can you go again, sweetheart?”
“What are you, an animal?” Katsuki grumbled. “Wasn’t that enough?” He leaned into Eijirou’s touch, the sweet caramel of his scent still sugary with arousal.
“You didn’t answer me.”
Katsuki tucked his head to the side, avoiding eye contact. “How would I know?”
His lips were shiny, swollen from being bitten over and over, and Eijirou had to kiss them to soothe them. Then he had to kiss them again, because Katsuki tasted addicting, and again because he’d moaned softly into his mouth.
He got even more sensitive after he came. Fuck.
Eijirou would decide for him, then.
He slipped his fingers into his own mouth—he wouldn’t want to hurt him, going dry— and slid his hand down over Katsuki’s pussy, circling two over his clit. Soft, delicate movements, but judging by Katsuki’s broken little moans they had to feel good anyway.
His mate came again when Eijirou sucked his unmarked scent gland. His eyes rolled in the back of his head and his mouth opened on a wordless scream, his clit twitching under Eijirou’s hand.
It wasn’t as long as before, but Eijirou worked him through it regardless.
He’d never get bored of Katsuki’s openly blissed-out face. No pretense, no anger, nothing but pure pleasure.
Eijirou caressed his inner thighs, drawing soft moans with every pass. They were wet with both sweat and slick, and they were so pretty. He wanted to mark Katsuki up there too.
He tried to slide his hand up again, but he didn’t get to continue because Katsuki whined and closed his legs, weakly pushing him away. “For fuck’s sake, Ei, let go.”
Eijirou was pretty sure he pouted. It was kind of selfish if you thought about it. What if Eijirou wanted to make him come again? Why would something as minor as oversensitivity get in the way of it?
“My clit is gonna fall off if you touch it again.”
“Are you sure you can’t?” Eijirou hoped he didn’t sound too whiny.
“Yes!” Katsuki snapped. He smiled, content and teasing. “You’d think a mate this into making me come would be a fucking blessing. You’re gonna kill me.”
“Fineee. I’ll be back. And for the record, that doesn’t sound like a bad way to die.”
Katsuki chuckled. Eijirou kissed the top of his head and stood up, returning with a water bottle from his mini-fridge and a damp hand towel.
“Don’t you wish you had a real Alpha now?” he joked as he ran the towel over Katsuki’s thighs.
His mate somehow found the strength to aim an explosion square into his face.
