He perks up immediately, breath catching in his throat as he panics. Bakugo will know whats wrong if he sees him. Don't roll over, don't roll over.

"Y-Yeah?" He whispers. Bakugos voice is quiet, and ragged. He obviously needs to be alone, and Kirishima isn't helping by continuing to stand here, but he can't help it. He feels like if he leaves, the omega will dissappear. Or get hurt, or...

"In the top drawer..." He whispers, and turns in the sheets, looking up at the red head. Kirishima's fingers twitch at his side's as he holds back a whimper at the sight of the blonds fine and soft upper torso. Fuck, he could totally sink his teeth into that chest.

"In the top drawer..." Bakugo mutters again, cheeks a perfect red as he pulls kirishima from his dirty thoughts,"Is a collar."

A... A collar?

Kirishima stares at him wide eyed. Bakugo hates collars...? He knows he hates collar. The blond talks about it constantly, about how omegas that wear collars- and let alphas lead them around everywhere- are pathetic. How people that do that are just encouraging the inequality between omegas and alphas.

He continues to blink at him dumbly. Bakugo gives a frustrated sigh, glaring at him through his teary eyes. Why is he on the verge of crying?

"Kirishima!" He bellows, and Kirishima blinks, eyes growing wide as his cheeks warm up.

"Sorry sorry!" He yelps, turning and reaching into the top drawer of Bakugo's dresser. He digs through it, searching for a collar that he never thought Bakugo would have. He flinches as his hand hits a wrapper of something, and his stomach drops out of him as he looks at the little square packets, his groin twitching to life again.

Condoms...?

Why does he have condoms? Kirishima stares at them for a split second before shaking his head at himself. That is none of his business.

He finds the collar. It's not small either. Its thick and black, the buckle looks heavy with metal, and the collar is atleast a half inch thick.

It's a... Mating collar.

His heart starts beating with new found curiousty. Why does Bakugo wanna put this on if he's not gonna have sex? He swallows, feeling out the leather strap. It makes his whole body feel warm with lust, his legs feeling weak as all his blood seems to drain to his dick. Fuck.

He turns back to the omega who's panting on the bed. Some part of Bakugo's mind is still holding on, his crimson eyes furrowed tight as he fights back the urge to fall completely into heat.

He reaches for the collar as Kirishima hands it over, and their fingers brush. Kirishima grimaces as only that little bit of contact makes his whole body flash with an unforgivable amount of arousal. Its like a cool bucket of water was poured over his hot body and all it did was evaporate on his scolding skin.

Bakugo quickly pulls the collar around his neck, just tight enough that it's not too loose. Kirishima stares at him, watching as his best friend grimaces, hand reaching to grab at his stomach, but he glances at the alpha and restrains from showing pain as much as he can.

They both sit at a standstill then. Kirishima knows he should leave. Now. But he doesn't move. And Bakugo seems to know that he needs to tell the other boy to leave, but he doesn't say a word.

It's silent as they glance at eachother nervously. Kirishima blushes even harder as he sees Bakugo's droopy eyes glance at the bulge in his jeans. Shit, he noticed already.

Bakugo looks up from the alphas groin, looking into his eyes. Kirishima wants to pull curtains across his cherry red face, embarrassment lacing through him, but he just can't seem to drag his eyes away from his best friends. Bakugo huffs heavily, eyes closing softly as he clutches at his stomach. He's hurting.

"Kirishima..." Bakugo whispers his name, and that's all it takes.

The red head is crawling into the nest before he can stop his feet, and Bakugo whimpers pathetically as the red head pushes him down, trapping those pale wrists above the blonds head. He leans close, immediately biting at the collar around the blonds neck as he pushes a knee between his thighs. Bakugos breath hitches quietly, his legs bumping around the alphas hips.

Oh, shit. Kirishima huffs, hands moving from the omegas wrists and to his chest, pushing him deep into the blankets. Bakugo's stuttered breath makes his stomach ache and curl, and Kirishima can't stop himself as he reaches down and moves the omegas legs up, placing himself between those thick thighs.

Bakugo isn't shy about what he wants either. Kirishima's body feels hot with embarrassment as the omega grabs his hand and slides it down to his groin. Kirishima is honestly shocked by how hard he is, and the blonds whole body jerks violently as the alpha palms him fully.

"Shit..." Kirishima whispers, leaning into the blond as he curls on top of him. Bakugo tucks his face into the alphas neck as Kirishima holds him close, hand still on the other boys crotch.

Bakugo huffs against his scent gland, and Kirishima flinches as gentle lips brush against his neck, then again, and again.

"Bakugo..." He turns his face into the other boys hair, kissing his head before moving down and kissing his cheek. He's never kissed somebody before, so when he comes to the omegas lips, he finds himself stuck between either kissing or shying away. He doesn't know how to kiss good; he's bad at kissing.

Bakugo fixes that problem, reaching up and roughly grabbing Kirishima's face, yanking him down into a kiss. Kirishima huffs, taking the gentle kiss. It makes him smile honestly. Bakugo yanked him down so rough, and yet the kiss is nothing more than lips on lips.

Shaky hands push through his hair, and Kirishima huffs as he presses closer, rolling his hips into the omega beneath him. Bakugo sighs into his mouth as their kiss deepens subtly. There's hardly any tongue, both of them inexperienced on so many levels. Kirishima huffs heavily, moving from the kiss and tucking his face against Bakugos neck as he thrusts his hips against the other boys crotch. Bakugo clings to him, strong arms wrapped over the alphas thick shoulders. Kirishima chokes on his own breath as the urge to reach his climax claws at his insides, hands shaking where they hold Bakugo into the bed. God he's so warm.

Bakugo lifts his legs up, lacing at the back of Kirishima's legs as he turns his head and nibbles at the larger boys ear. Kirishima chuffs, nose pressing into the collar as he seeks the sugary smell of vanilla and the spice of cinnamon. Bakugo's hands push beneath his shirt, sliding up the red heads back, nails digging into his back.

"I want you..." Bakugo's voice is rough in his ear, with just a little bit of a whine behind it, and Kirishima hums, hands pulling the blond omega closer against him. Bakugo gives a stuttered breath, hand leaving the red heads shoulders, and Kirishima gasps softly as he's grabbed through his pants.

He reaches down, and its like their minds are linked as one. As soon as Kirishima's fingers are touching the hem of the other boys joggers, Bakugo lifts his hips and they slide down to his knees like this isn't the first time either of them have done this.

Kirishima takes a deep breath, rubbing his hand around the omegas stomach before sliding his hand down. Somewhere inside his heart he's screaming at himself, telling him this is wrong, that what they're doing right now is wrong. This is wrong and too fast, way too fast.

But his instincts. His instincts scream at him, telling him to rip the collar off, telling him to fuck the blond so deep into the sheets that he gets the omega to whimper with pleasure. And thats the side that's clouding his mind. That's the part of him thats taking over.

But he's gentle. He'd never hurt Bakugo. Never. He doesn't even know if he could though, Bakugo is so fucking tough.

"If I..." Bakugo huffs, eyes squinted as his hips twitch into Kirishima's touch,"If I say stop. You fucking better."

"I will..." The red head whispers. Holy fuck, when did his voice drop an octave? Bakugo seems to notice it too, his eyes growing wide before looking to the side.

Kirishima smiles. Somehow, in this room full of fluttering scents and heightened instincts, he finds himself unable to contain his fondness for Bakugos shy side. It's so cute, it always has been.

He slides his hands over his partners rock hard erection, getting a choked sound to escape the blonds throat. That alone makes Kirishima wanna rut into him, but he can't force this.

Especially when they're... So inexperienced like this.

Bakugo is wet as he slides his hand lower. He doesn't look, too afraid that if he does, he'll fall into rut. He can feel the alpha inside him screaming to let loose, but with his determination combined with the meds, all Kirishima can do is go off the lust that only normal betas can feel. Which he hates, he'd love to do this with Bakugo as a true alpha but... That's impossible for now.

His finger finds the blonds entrance with ease, and Kirishima flushes impossibly darker as he feels the slick that seems to cover the omegas whole underside. The thought of pushing into that makes his gut roll up and flatten out again, his chest squeezing to nothingness.

Bakugo covers his face, mouth twisting into a strained frown. Kirishima swallows tightly, the lump in his throat making it hard to breathe as he leans down and kisses the other boys lips softly.

And then he pushes his middle finger in. He pushes it all the way too, afraid he'll chicken out if he doesn't. It's tight, and warm, and Bakugo clenches his jaw, a sharp breath coming out of his nose, hips shifting into it and back arching.

Kirishima bites the inside of his cheek, suddenly very aware of the warmth around his finger. He tries his best to calm himself down, but he isn't sure how to do this. He's watched porn, yeah, but the real life thing is way fucking different.

He kisses Bakugos lips again, pulling his finger out some and pushing it back in. Bakugo hums, mouth opening to pant against the alphas lips.

Bakugo's hand comes up, yanking on the other boys hair gently as he keeps his face hidden beneath his other arm,"Kirishima..."

"Yeah?" He kisses the corner of the omegas mouth.

"Stop." Bakugo finally moves his arm, reaching down and grabbing at the red heads arm. Kirishima swallows, and does as he's told, pulling his finger from the warmth that cascades it and silently missing it. He looks up at Bakugo's face.

The blond grimaces hard, eyes staring sharply at the ceiling,"I don't want you in here right now." He mutters, voice raw. Kirishima swallows tightly, suddenly feeling very unwelcome.

"I'm sorry." He whispers, and Bakugo looks to the side, and Kirishima can see tears. He feels like he's done something incredibly wrong as Bakugo covers his face again.

"Just get out." He whispers back. Kirishima presses his lips together, brows furrowing with worry. Did he... Did he force himself on Bakugo? Is that whats happening here? Did he force himself on Bakugo and believe the omega liked it.

"Get out Kirishima." Bakugo presses a foot to his thigh, pushing lightly,"Go. I'm in heat, I don't wanna do this."

Kirishima bites his jaw, feeling tears ebb into his eyes. He's being rejected right now, isn't he? He knows he didn't force himself on Bakugo as he thinks about it. Bakugo told him he wanted him, so it wasn't forced. But at the same time, that could've been his omegan instincts seeking out the nearest alpha, and he probably wasn't seeing Kirishima as Kirishima, but rather he saw the red head as an alpha.

And now Bakugo seems to be in a down low, the heated moment is gone, and he seems to be a little more sane than before. He must've realized that the other boy was the one he was kissing. He must've realized this was a mistake.

He takes a deep shuddering breath before shifting away from his best friend, his chest knotting up so tight that its hard to breathe. He holds back his tears, stepping back a few feet and looking off to the side as Bakugo pulls his joggers back up.

"I'm sor-"

"Get out, fuck." Bakugo's voice wavers, a clip to the end of it, and that makes the alpha grimace worse than before, forcing his ruby eyes to glance over and find the omega hiding his face beneath his arms, laying in the nest helplessly.

Kirishima tries to rid his throat of the lump that's suddenly formed as he forces his feet to move, his limbs suddenly feeling like led.
