Bakugou was an alpha.
All Kirishima could focus on was the slick sound the fleshlight was making around Bakugou's dick and the way his best friend was thrusting up into Kirishima's palm like it was the last thing he'd ever do. Kirishima had to harden his free hand against the headrest to stay steady—to not get rammed into the wood with each forceful thrust—and it hit him over the head for the first time that Bakugou was an alpha. Really, truly an alpha. Before that it hadn't really sunk in. He'd just been treating Bakugou like he always had—like his best friend, his first real crush—had held onto a flimsy shred of hope.
Kirishima had known, of course. Everyone had known what the blond would present as when the time came. Bakugou was textbook alpha, posturing and feral attitude fitting the stereotypes down to a T. In fact, Kirishima hadn't even been slightly surprised at the way Bakugou had pinned him down on the training field the day before, the heady and bitter scent of rut pouring off of him, soaking them both down cold with sweat. The only thing that had shocked him was the tight feeling in his chest afterwards in the locker room as he rubbed his best friend's hostile scent from his skin.
Some part of Kirishima had been a little disappointed. It made him feel bad for feeling it. Bakugou couldn't help what he presented as; it was written into their very genes. It was just that now Kirishima had no chance. None. Alphas didn't work well with other alphas. There was the nose-stingy scent that made Kirishima's eyes water, the territorial instincts, the hair-width tempers and posturing. Forget romance, Kirishima wasn't even sure if they'd be able to keep the friendship they'd perfectly crafted over the years. That was what frightened him the most.
He'd seen how secondary genders could rip people apart.
Kirishima winced as nails sunk into his shoulder and he gently wrapped a hand around Bakugou's wrist, trying to pry them from his skin. Bakugou growled at the perceived insubordination and the grip only got tighter, forcing Kirishima's back against the wooden headrest.
"Bakugou." Kirishima pitched his voice a little higher so that it wouldn't be perceived as a threat, "hurts."
Bakugou's hips stopped for a second, a flash of something zipping through his eyes, before he leaned down and gently licked the spot he'd accidentally torn into. Mating instincts Kirishima thought a little distantly. He squeezed his hand a little harder around the jelly plastic of the fleshlight to get Bakugou going again and breathed out when the other alpha got the message.
The sooner it was over, the sooner Kirishima could rinse his hands of this and pretend it had never happened. Maybe Bakugou would pretend too and then it'd be perfect. It felt awkward, more than anything, to be helping his crush through his first rut. It was weird for everyone the first time, but usually there were parents there to help their kid through the experience. Older siblings. But of course Bakugou just had to be first to get everything except for his secondary gender designation.
Kirishima tried to ignore the heat that rose up his neck as he felt the toy stretch beneath his fingers, having been torn past its limits by Bakugou's growing knot. Fuck, that was Bakugou's first knot and Kirishima was the one who got to see it. First one to (kind of) touch it. The thought made his own alpha lap possessively at the inside of his chest and he pushed it down. Down boy. Bad dog.
"Dang, I guess it's a size too small, huh?" Kirishima tried to joke around the lump threatening to close his throat. His skin felt so warm, dry against Bakugou's heat. The blond was like a furnace in general, but now especially. His skin ran hot, making every accidental brush of their arms or legs burn for seconds after the contact. Bakugou looked up at him hazily, sweat trekking down his cheeks and neck, blond lashes plastered together, and Kirishima swallowed a little too forcefully.
"This yours?" Bakugou asked, words slightly slurred and labored with harsh breaths. It was the first coherent thing he'd said since they'd gotten started and Kirishima felt his stomach twist up.
"No! I wouldn't give you mine dude, that's..." Kirishima didn't really know what that was. He was pretty sure gross was how most alphas would have ended that sentence but it didn't really seem like the right thing to say. Especially not since Bakugou's face turned dejected and his thrusts went soft for a second before his rut hormones spurred him on again.
"—That'd be kind of weird," he finished lamely but Bakugou didn't seem to be listening anymore anyway, eyes squeezed shut as he pounded into the toy. After a few seconds his body seized up and Kirishima had to harden his back as he was shoved towards the front of the bed with the last forceful push. The wood rammed against the wall, white paint flaking onto his shoulders, and he choked briefly on the spit he swallowed from the sudden movement.
Kirishima looked down and noticed that the toy was truly wrecked, filled with an honestly horrifying amount of come, and the entrance was wobbly where the structure had gotten torn into. It was a little scary. It also made Kirishima's pants achingly tight for some reason. He didn't want to be the toy. In fact, his inner alpha was growling at the obvious display of another alpha's prowess, but it was undeniably fascinating. Kirishima was just glad that he'd taken extra suppressants before coming over. His brain always felt a little hazy—like it was submerged under a thick layer of water—after taking more than his usual dose but it was worth it. He didn't feel any urge to posture at Bakugou and his smell was placated enough to be tolerable to the blond.
"Good thing I brought a backup toy," Kirishima smiled as his fingers carefully unwrapped from the ruined toy. When he looked down he noticed his hands were trembling with adrenaline and exertion so he quickly hid that fact against the sheets as he leaned over the side of the bed to get the still-packaged rut toy he'd picked up yesterday after Bakugou had gotten dragged to the nurse. When he turned around he saw Bakugou pulling at the toy trapped around the base of his knot with a frustrated look on his face and Kirishima's eyebrows shot up, "hey— hey, uhm, don't do that. It's not good to pull out until the knot goes down."
Bakugou narrowed his eyes but stopped tugging with another huff, his gaze piercing and clear in the after-orgasm. He still wasn't Kirishima's best friend though. Right now Kirishima was just dealing with a whole bunch of instincts and hormones bundled up into the shape of his best friend. The real Bakugou was trusting him to walk this addled version of himself through his first rut and Kirishima wasn't about to go and fail his best bro.
While the knot went down, Kirishima slid off of the bed and stretched, feeling at least a dozen cricks unwind in his shoulders and back. After that he went to the side table and opened a small, plastic square of wet wipes. He wiped his scent glands down—making sure none of his alpha scent managed to sneak out and aggravate anything—and then kneeled back on the mattress and wiped down Bakugou's sweaty face with a new wipe, grinning at the way the blond jerked away from it like a cat.
"Sorry," Kirishima smiled as he drew back and tossed the wipes into the wastebasket across the room. "You hungry at all? We probably have a few minutes before—" Kirishima's eyes drifted down but he snapped them back up just in time, "before it starts again. You have to remember to eat and drink."
Bakugou didn't say anything but his gaze hadn't budged from Kirishima at all. Does he think I'm a threat? Kirishima tried to subtly sniff himself but he didn't notice any smell that wasn't Bakugou's own rut. He picked up a bag of chips from the end of the bed and opened it, holding them out to the other boy in a way that he made sure looked similar to how betas used to offer food to the alpha of their pack. It was only then that Bakugou took it and pushed a few chips into his mouth. Kirishima had gotten the blond to drink an entire bottle of water before they started so they were still alright on that front.
What else had his father taught him? Kirishima tried to think back to his first rut but the entire ordeal was a huge, hazy gap in his memories and he was honestly kind of grateful about it. With any luck, Bakugou would learn everything he had to know and then forget the rest.
Kirishima jumped when a hand landed on his knee and when he looked down he saw that Bakugou was hard again, straining obscenely against his thin boxers. It was like the fabric wasn't even there at all with how it was stretched so tight around the erection. There was a damp spot in the front and Kirishima sucked in a fast breath before he scrambled for the new toy. He cracked it out of the packaging and got himself settled back by the headboard again.
"Okay, just do what you did before. It takes a couple of times before the rutting urge goes down for the day," Kirishima said, voice tight with forced normalcy. He'd spent the last couple of years imagining Bakugou undressed, him hard and desperate in bed, and none of the scenarios had gone down like this. Had gone down with Kirishima feeling guilty and sick and like more of a mentor than a lover.
Bakugou pushed between his thighs again, palms cupping his erection, and Kirishima let his legs get manhandled around Bakugou's hips as the blond lined up his dripping dick with the new toy. His eyes shut as he felt the toy fill out under his fingers. Bakugou's dick was so fucking thick. Even this toy was struggling to take it, the jelly going tight and thin as it was pried open. He startled when something slick brushed against his wrist and his entire body flushed when he realized that this toy had a tiny hole in the top that Bakugou's dick had instantly stretched out. Precome dripped onto his wrist, thick and white, and it felt like his skin burned at the touch of it.
"Sh— Shit." Kirishima jerked his hands away and the moment his hands stopped supporting the toy, Bakugou's gaze snapped up dangerously. The look made the bottom of Kirishima's stomach drop out and he felt himself freeze on the sheets, breathes going shallow as alpha instincts lit up his insides. Dangerous. Alpha.
He scooted backwards but Bakugou's hand snapped around his wrist so fast that it was hardly visible. Those claws were the reason Kirishima was holding the toy in the first place; it took a few ruts to get used to the sharper fangs and extended claws and accidentally nicking the goods was unfortunately common among newly presented alphas. Kirishima's heart sped up, blood pounding in his ears as fear and arousal curled in his stomach. Bakugou leaned forward with a growl and Kirishima forced his head down in submission, not wanting their lesson to end in bloodshed. If Bakugou had to bite him to show dominance, he'd let him. Trusted him not to make it scar. Instead of a bite though, Kirishima felt a soft, wet heat engulf the flesh at the bottom of his thumb. He gasped and a hint of teeth grazed his skin as Bakugou's mouth slipped down to where his precome had gotten onto Kirishima's wrist.
Like a tap, arousal flooded into his blood, making his skin go as hot and sensitive as the blond sucked at Kirishima's wrist. It was like something out of one of his dreams; the dreams Kirishima had sometimes where blurry images of blond hair and chapped lips faded in and out around him. Fuck. Kirishima always woke from those dreams so hard and he was all but straining out of his sweatpants now.
A pleased rumble slipped from his throat before he could stop it and the other alpha instantly latched onto it.
With a shove that was just a touch rough, he was pressed flat against the mattress and Bakugou's solid weight settled over him, legs pinning him down. The feeling of Bakugou's bare erection—where had the toy gone?—brushing against his stomach where his shirt had ridden up finally made Kirishima snap out of whatever arousal-fueled haze he'd fallen into. He twisted under the small but sturdy body holding him down but the blond didn't budge, all tight muscle and perfect balance, and that's when the panic hit.
His body was alight with confused signals as a part of his brain made him push his hips up against Bakugou's perfect weight and the other part yelled at him to get away, that everything about this was wrong.
And it was wrong. Fuck, it was so wrong. Bakugou trusted him as a friend to not fuck this up and Kirishima didn't want to mess up any of the blond's future ruts because he has weird ideas about how it was supposed to go. It was his fault for losing focus. For getting aroused at all.
"Wait— Shit. Bakugou calm dow—"
There was a snarl and then a calloused hand was shoved unceremoniously into his hair, dragging his head down into the pillow. It stung a little, where the hairs tugged at his scalp, and his eyes clenched as the pain only got worse the longer the tight grip stayed. He was breathing a little too fast. Too wheezy.
"Be good." Bakugou growled and it made a shuddery heat run from the tips of Kirishima's toes to where the fingers were clenched in his red hair.
"I'm not good. Not an omega. Or a beta," Kirishima gritted, a sick feeling rising up his throat as his inner alpha rebelled against the suppressants he'd taken earlier. He was going to get sick if this kept up. If his instincts kept trying to flare up and battle against the pills he'd taken. He was going to puke all over the bed and Bakugou would be disgusted and, hell, Kirishima would be too.
"I know what you are," Bakugou said, voice low and gravely.
"An alpha," Kirishima finished, eyes hard as he stared up into red eyes.
"No," the other alpha responded with a deadly calm, "you're mine."
Words failed on Kirishima's tongue as his eyes went wide. A warm feeling engulfed him, filled him up. His body went lax with shock and suddenly Bakugou's wet length was hard and sliding against his abs, marking his skin with the smell of musk and bomb residue. The length slid up to his chest, got pushed between his pecks, and Kirishima flushed at how illicit it looked. Flushed at the fact that he was just letting it happen. With his shirt pushed tight under his armpits, he could only watch as the erection slid in and out of the cleft of his chest. Bakugou's hips were gyrating on Kirishima's stomach, his fist still tangled in red hair, and all Kirishima could think about was what Bakugou would look like if he were riding Kirishima's dick instead. How fucking breathtaking he was. It made his head spin.
His fingers brushed up Bakugou's thighs to grab his waist and with a sudden snarl and a stutter of his hips, Bakugou came all over Kirishima's chest, neck, and cheek. There was so much come and it just kept going forever, painting Kirishima's skin with it in long stripes.
For a second Kirishima was shocked into silence. His own dick gave a sympathetic twitch at the same time his inner alpha leapt out at the fact that another alpha had just very explicitly scented him so completely. He growled, straining against the weight on top of him but Bakugou slammed him back down with another harsh tug to his hair. "Mine."
Fuck. Kirishima liked that. He liked the possessive and cocksure way Bakugou said it too. It all went straight into his ears and down to his dick. Still, he only had a few minutes before Bakugou's erection woke up again and while sometimes things happened during ruts, they didn't usually happen twice. Especially not in the same session. Not between two alphas. Not like this.
With how fucked out Bakugou was, Kirishima finally managed to wrestle him off and over onto the side of the bed, only taking a few nails to his side in the process.
"Look, you can't do that. We use the toy, okay?" Kirishima said, doing his best to sound serious and not like he had the hardest erection he'd ever had pressed real tight against his inner thigh.
Bakugou stilled his attempts to escape and his eyes narrowed dangerously, "you smell." Bakugou took in another breath and his eyes went slightly hazy as he slowly met Kirishima's gaze again, "like you want me."
Fuck. His arousal was definitely going to confuse something important in Bakugou's subconscious if this kept up.
"I'm an alpha. I don't know what you're smelling but, uhm, look let me wipe down my scent glands again and we'll use the toy like we were before. Yeah?"
Bakugou's body finally went somewhat lax with afterglow and he just sort of nodded before curling in on himself on the bed as Kirishima got up. He pulled on a new shirt from the discarded pile of clothes in a pile on the floor. Then he rubbed the scent-clearing wipes over all of his glands again and then hesitated for a second before sitting back down on the bed. The mattress dipped a little but Bakugou didn't turn to look at him, his knees tucked against his chest in a way that made him look tiny and soft. It made Kirishima want to curl around him but he pushed down the errant urge and forced himself to sit against the headrest again. He found the toy they'd been using in-between blankets and held it out between his thighs.
"Ready when you are," he breathed, voice only shaking a little, "the edge should go down once you knot this one, since you're already starting to be able to talk again. After that you should sleep and I'll help again when you wake up. A few more times after that and you'll be done with the rut!" The false cheerfulness in his voice grated on his own ears.
He waited, but Bakugou didn't pull himself out of the compact shape he'd fallen into. His dick was straining in his pants but the blond alpha didn't move, his shoulders falling up and down with labored breaths, but the rest of him was unnaturally still.
"Bakugou?" Kirishima's brows furrowed and he set the toy down again as he kneeled beside his friend. He tentatively placed his hand on the other alpha's shoulder and rubbed small little circles, "uhm, sometimes weird stuff happens during ruts. I know it's hard to control the alpha sometimes. It's okay, we'll just forget about it once it's all over. It's really not a problem, man."
There was a dry laugh in response. They sat like that in silence for another minute before the blond spoke again:
"You used to want me."
Bakugou's voice was muffled against his sweatshirt but Kirishima still heard every word. Each one of them made his pulse climb until it was all but pounding in his ears. He pulled his hand back and realized that he didn't have the slightest idea how to answer. Agree? Disagree? Deflect?
Kirishima laughed nervously and ran his fingers through his hair, "we should get back to dealing with your rut. It'll start to get painful again soon." Deflection it was.
Bakugou was silent for another few seconds before he quietly uncurled himself and got back onto his knees. There was an odd silence and Kirishima felt the weight of it as his thighs were pushed open again and Bakugou's scent swept back into his nose with a new intensity. They were so close, nose-to-nose, just like they'd been before but this time Bakugou's eyes were bright with awareness. A deadly kind—hyper vigilant—with the rut haze no longer clouding them. It made Kirishima's lungs feel like they couldn't take in a full breath. He forced himself to pick back up the toy and felt his instincts prickle up his spine when Bakugou's hand stoped him.
"I don't want it."
"I— Bakugou, we need it to get your knot to go down."
"I don't want it." Bakugou reiterated, voice steady and words sharper this time. "Just your hand. Please."
Kirishima stopped breathing for real for a second. His fingers twitched but he kept a firm grip on the toy. He wanted to so bad. Wanted to milk Bakugou's knot with his fist until it came all over his arms and stomach. Until it marked him in thick stripes again. "I can't do that."
Something twisted in the other alpha's complexion; something that looked startlingly like the onset of tears. "Why? Because I'm an alpha? I'm disgusting to you now, is that it."
Kirishima felt his own complexion break for a second. He didn't know the answer to that question either. It seemed obvious that two alphas couldn't do things like that with each other. At least that's what everyone said. It didn't matter what they'd had before; the unspoken of tension that had lined their relationship like an undercurrent. Now that was all just a pipe-dream with no happy end.
"Yes." Kirishima finally got out, the word flimsier than he'd originally intended it to be.
Bakugou's eyes were like daggers, "why? What the fuck makes things so different now? I know damn well that just last week you were all but drooling over me in the locker rooms."
He sounded petulant, angry. A rebel, like always. So very alpha that it just hammered in the point that he was trying to disprove. It made Kirishima's heart swell to twice its size and that was no good. He leaned away from the other boy and tilted his chin up, meeting his eyes head-on for the first time. No submission.
"Because every one knows that two alphas can only hurt each other."
He let the words hang in the air as he felt his own alpha instincts prickle at the full-on eye contact. It was a challenge, especially when one or both alphas were in rut. Bakugou definitely felt it too, if the way his teeth clenched and his jaw went taunt was anything to go by. They stared at each other, malice filling each of them up before Bakugou snapped and he lunged forward with a snarl, throwing Kirishima back against the headrest. Kirishima hardened just in time and grunted at the impact before quickly lowering his head again. He let his eyes shut in submission. The bed creaked dangerously beneath them.
Their breaths were too loud, disrupting the silence.
"See?" Kirishima whispered hoarsely. His spine ached, as did his gums where his alpha instincts were converging; where they were trying to get him to retaliate, to bite. If he hadn't been doped up on an excess of suppressants, he probably would have given in to the urge. Which was precisely the problem, wasn't it?
Bakugou immediately dropped him, his eyes going wide and startled as he looked down at his hands. At the splintered headrest. At Kirishima's scrunched face.
"I didn't mea—"
"I know you didn't. It's instinct. We can't help that," Kirishima said with a grim, small smile. His voice almost shook but he didn't let it. He sniffed, rolled his bruised shoulder, and then smiled as brightly as he could. With a steel-like determination he forced his shoulders to square again and lifted the fleshlight, "it's the rut talking. C'mon, you're almost done for today. The first time is confusing for everyone." Not usually confusing in quite this way, but Kirishima wasn't going to say that. Bakugou probably knew that much already anyway.
I'm not confused was written across Bakugou's face but neither of them spoke again until Bakugou finally nodded an almost imperceptible nod. He didn't argue or talk as he wrapped a steady hand around his dick and slid it home again into the fleshlight. Both of them were tense but Kirishima moved first, sliding the toy up and then back down with a slick, wet sound. The little groans Bakugou tried to suppress at each stroke, the way he caved towards Kirishima's chest on unsteady arms, made something hot and dangerous well up in Kirishima's gut the further they got into it. He clenched down a little harder around the jelly and Bakugou seethed, his eyes flicking up before they snapped back down, his canines sunk deep into his bitten lip.
Kirishima wanted to touch him so bad.
It felt like a burning, like an itch.
His cheeks were as flushed as Bakugou's as he twisted the toy a little, selfishly delighting in a sound of pleasure it wrung out of the other alpha. It was wrong, but now they both knew that this was the most they were allowed to have. This was all that could come of years of sexual tension. He was so close to getting what he'd wanted and yet this was the end. The full stop.
"Come on, almost there," Kirishima coaxed as he set a punishing pace with his fist. Bakugou's forehead was pressed damply against his chest and he was bowed over in a way that showed off his perfect nape, bordered with blond hair that clung to his neck with sweat. It was a beautiful sight and an even more beautiful feeling. Kirishima felt on top of the world right then, with Bakugou shaking, collapsed against him with pleasure. When he came, Bakugou's teeth sank into Kirishima's sweatshirt but they didn't go deeper than that. His canines tore at the cloth viciously, the sound of it tearing drowned out only by the pitiful sob that accompanied it. Kirishima murmured him through it with soft praises and encouragements.
"Good job, you did so good," he breathed when he felt Bakugou's dick throb through the jelly.
Kirishima squeezed the knot at the base tentatively before he slowly unwrapped his hand from the toy and helped maneuver Bakugou onto his side to recuperate. Bakugou went down easily, face damp with sweat and eyes shut with exhaustion, and Kirishima let himself collapse against the headrest as well. His skin still felt too tight for his body and his erection hadn't gone down at all since it'd first gotten the idea to get excited.
With a tired huff, he wiped off his forehead and leaned over the side of the bed to pull out the tissues. He wiped down his sweatshirt—which had gotten painted with a liberal amount of come—and then slid Bakugou's softened knot out of the toy and wrapped the fleshlight in a couple tissues as well so it wouldn't make a bigger mess of the sheets. After that he pulled up Bakugou's sweatpants and busied himself with cleaning the rest of the bed.
When everything was put away Kirishima awkwardly stood at the foot of the bed, unsure of what to say.
"I'll come back tomorrow morning around eight if that's okay."
Bakugou nodded against the pillow, his face hidden. He was curled up again and Kirishima's chest tightened painfully.
"I'm just next door if you need anything."
No response.
Kirishima's fists tightened in his sweatshirt a few times before he rounded the bed and kneeled on the floor.
"Hey, can you, uhm, look at me?"
Bakugou didn't move for a few seconds but then he raised his head. His cheeks were still flushed with exertion but this was his best friend that he was talking to; the beast had all but receded back inside.
"Are you okay?"
"I'm fine." Bakugou muttered, looking down at the sheets.
"We're good, right?"
A pause, but then Bakugou nodded, "yeah. You're my best friend."
He looked up then, like he was expecting a challenge to that. Kirishima just smiled in return and watched some of the tension leave Bakugou's shoulders.
"Yeah, best friends," he agreed. At least they could still have that. Alpha-alpha friendships weren't that common but they also weren't taboo. Besides, Kirishima was hardly that offensively alpha in the first place. He could control most of his more base instincts to some extent; just not to all of them. Something wobbled across Bakugou's face but he schooled it back into place firmly, "thanks."
"That's what friends are for, right? C'mon, let's get some sleep. You probably need it after all that. I remember I was exhausted after my first day." He pulled up the new blanket and let himself smooth it over Bakugou's shoulders before he pulled his hands away. Bakugou's hand wrapped around his wrist before he could withdraw it all the way. That was becoming a trend; a trend Kirishima liked a little too much. It reminded him a little of the first time Bakugou had reached out and grabbed his hand.
"I—" Bakugou started and then his voice broke off.
Kirishima held his breath.
"I wanted to be an omega. Or even a fucking beta. I didn't want this." The blond alpha finished, his voice cracked in all the wrong places.
The I wanted to be an omega for you didn't need to be said.
Kirishima swallowed. A profound sadness threatened to spill over inside of his chest. His eyes were too wet so he blinked a couple of times. He knew his voice wouldn't work so instead he slipped his hand into Bakugou's and squeezed it tightly. He felt the calluses against his skin; the warmth and hardness and familiar pressure. He clung to the touch until he couldn't take it anymore and lifted Bakugou's hand to his throat instead.
His heart pounded against his ribs—part in terror, part in elation—as Bakugou's fingers curled around the back of his neck, over the scent gland there. Finger tips grazed the tiny, wet indent at the center of the gland and a low growl slipped past his lips on its own. He didn't move though; he stood rigid still and let Bakugou touch him in the most intimate spot an alpha had. His breaths were shaking in the air between them and Bakugou was looking up at him with wide, stunned eyes.
Finally, his inner alpha snapped and Kirishima ducked away from the touch with a gasp.
Still, he saw his scent glistening on Bakugou's still-extended hand and swallowed another wave of hot arousal at the sight. Slowly, Bakugou retracted his hand and examined the wetness before flicking his eyes up as he slid two fingers into his mouth. Alpha scent was supposed to be vile to other alphas but Bakugou's face was nothing but flushed with desire as he first tasted and then dragged the scented fingers back across his own throat like a knife.
Kirishima moaned at the sight, his legs bending against the side of the bed, as his body lit up from inside. He had to wrestle with his inner beast for a few seconds before he got it under control and he spun away from the bed to keep himself from crawling back onto it. There was something happening between them. Something good and potent and electric. It made hope flutter in his heart again for the first time.
But he wouldn't do anything while Bakugou was rutting.
He took a step away and then another.
"We'll talk about this after your rut, okay?" He grit out, his voice almost as strained as his pants.
"We will," Bakugou readily agreed, voice just as rough, "I won't let you forget."
Kirishima thought that the idea that he could forget was laughable.
Bakugou's pleased scent followed him out the door.
