Katsuki isn’t quite sure how this happened…
As the only alpha in Class 1A, he supposes that he should’ve seen it coming. It started out small like being asked for a scented item here or there. He would gripe about it, sure…but he’d always hand it over, knowing full well that he’d never see the item again. Then, came the random soft touches…a hand on his shoulder or fingers trailing across his back as someone passed by him in the hall. The omegas in his class have always been the more tactile of the group so he brushed it off as just a normal occurrence.
But now, as he’s getting ready for bed after studying for several hours, a quiet knock sounds at his door, interrupting the silence that had settled over the dorms hours ago. He grumbles to himself at the disturbance, but as he nears the door, the soft scent of syrup coated waffles wafts into his nose and his alpha purrs… Omega. He already knows who’s behind the door when he cracks it open to see Denki standing there, holding a blanket that Katsuki had previously scented before the omega’s last heat. He now keeps a stash of scented blankets just for the omegas in his class (Shhh don’t tell anybody that he’s that soft).
“Hey, Kacchan, can I come in for a bit?” Denki asks and instantly Katsuki is on guard at the subdued nature of the normally hyperactive omega.
Instead of his normal snarky retort, Katsuki feels concerned. “What’s wrong?” he asks gruffly instead.
Denki blinks at him, eyes drooping in exhaustion. “Just couldn’t sleep and your scent usually helps, but the blanket doesn’t smell like you anymore,” he murmurs almost shyly, like he’s afraid of rejection.
Katsuki’s alpha is smug in satisfaction that the omega likes his scent and is seeking it out. Katsuki cracks the door open further in invitation. Denki gives a relieved smile and hustles through the door before Katsuki can change his mind.
Katsuki wordlessly closes the door and when he turns around, he startles to find Denki wrapped in the blanket and sitting on the bed. He’s never allowed anyone in his den before and something pleased swells within him at seeing the omega in his space. Denki’s nostrils flare as he takes a deep inhale through his nose and then does a happy little wiggle that Katsuki secretly thinks is adorable.
“It smells so good in here,” the omega says and a happy purr starts to rumble from his chest. Katsuki blinks, having never heard any of the omegas purr before. They only purr when they’re truly content and the sound settles deep into Katsuki’s bones.
He tries to cover his sappy domestic thoughts by holding his hand out for the blanket. Denki glances at his hand, but seems reluctant to release the blanket around him. “Dunceface, I can’t scent it if you don’t hand it over,” Katsuki chides in a more gentle tone that he’s used to hearing from himself.
Denki looks a little stricken and Katsuki instantly wants to soothe him. He does quick math in his head and scents the thickening sweet smell in the air. The omega’s heat is in a few days…Suddenly, Denki’s actions make more sense. Usually, the omegas keep things platonic and he’s never been asked as the unofficial pack alpha, but he knows that as omegas age their pre-heat symptoms increase. Katsuki paid attention in his Dynamic Studies Class, thank you very much. An omega’s need for pack bonding, scenting and physical contact increases right before their heat, especially if unbonded. They’ll seek out the closest alpha that they feel safe with and initiate contact. He thinks back over his interactions over the last year and wonders if there were other signs that he missed. All of the omegas cycle together and they always get more touchy closer to that time, but he’s never really acknowledged or encouraged their behavior. Has he been neglectful as their pack’s alpha? His alpha whines in response to the thought and Katsuki has a sinking feeling in his gut. Shit, he knows that he’s often snarky and defensive, but he never wants his packmates to feel like they can’t come to him.
Katsuki retracts his hand, but steps forward to kneel onto the bed. He crawls over the mattress and settles with his back to the headboard. “Well, c’mere then,” he says and holds out one arm. Denki turns to him and his whole face lights up in excitement. He scrambles over the bed and tucks himself right under Katsuki’s arm, snuggling into his side with the blanket still wrapped around him. Katsuki tugs him closer under his arm and a sudden urge strikes him out of nowhere…he nuzzles fondly down into bright blonde hair, drawing in a deep lungful of happy omega.
“Thanks, Kacchan,” Denki whispers, laying his head over Katsuki’s chest.
“Don’t thank me, dumbass…” Katsuki rumbles fondly, unable to pull his nose away from the content scent radiating and mixing with his own in his den. His alpha tugs at him and he finds himself reaching down to grab Denki’s hand. The omega looks at him in question, but Katsuki just lets his instincts guide him as he swipes their wrists together. The purr rattling from Denki’s chest suddenly heightens and his eyes flutter a little, making Katsuki smirk. He’s never scented any of them, he’s never been asked, but seeing Denki this happy is definitely creating a warmth in his chest.
Another knock on the door startles them both. “Who is it?” Katsuki bites out, keeping Denki tucked to his side and very reluctant to burst the content bubble that has formed around them.
“It’s me, bro,” Eijirou calls through the door. Katsuki’s alpha urges him to answer it.
He slowly leans away from Denki, “Let me just see what’s up, k?” he murmurs. Denki looks sleepy and just nods his head. Katsuki scrambles over the bed and makes his way to the door where the smell of cranberries laced with anxiety filters through. Katsuki’s alpha growls at him to fix it. He yanks the door open and finds Eijirou there, fiddling with his fingers and his cheeks pink.
“Hey man, I know it’s late, but I was wondering…” Eijirou hedges.
“Just get in here, Shitty Hair…” Katuski clips out, opening the door further. He gets the feeling that he already knows what Eijirou needs. Eijirou gives him a megawatt grin and hustles into the room.
“Hey, Ei,” Denki greets groggily from the bed, where he’s laid down curled into a ball.
“Oh, hey bro,” Eijirou says brightly. “Didn’t know you were here. Am I interrupting something?” he then asks hesitantly.
“No,” Katsuki says simply and crawls back up onto the bed and sits back into his same position as before after putting a pillow behind his back. Denki automatically shifts and lays his head in Katsuki’s lap. Eijirou looks at them both, something longing in his gaze as it shifts to the side as if he thinks he’s seeing something he shouldn’t.
“Sorry guys, I’ll just–”
“Get up here, Shitty Hair,” Katsuki murmurs, feeling uncharacteristically soft tonight. Denki is still happily purring in his lap and Katsuki reaches down to stroke his fingers through the longer soft strands, mixing the black with the blonde.
Eijirou hesitates, shifting anxiously, “Are you sure, bro?”
Katsuki cracks an eye open from where they’d closed as he leans his head against the wall. He holds out his other arm. “C’mon…” he encourages in a quiet growl.
Eijirou is careful as he crawls up over the bed and under Katsuki’s arm as if he’s afraid to be a bother. Katsuki’s alpha chuffs, pleased when Eijirou takes a deep inhale and the tension in his body seems to flee him in a rush. Eijirou snuggles down against the wall next to Katsuki and Katsuki feels just a little more complete inside.
“Thanks, bro,” Eijirou whispers. Katsuki just grabs his wrist, making Eijirou jump at the sudden contact. Katsuki usually never initiates touch first, but his instincts are roaring at him to scent the omega…to claim them both as pack and make them happy. He rubs his wrist over Eijirou’s in slow circles while Eijirou looks on in curiosity until his lashes begin to flutter just as Denki’s had. The omega lets out a low groan that has Katsuki’s alpha perking its ears up. A steady purr rises up to join Denki’s in the room.
“There we go, omega…” Katsuki croons and releases Eijirou’s wrist to pull him in tighter to his side. Eijirou looks drunk as he tucks his face in Katsuki’s neck, his soft warm breaths tickling over Katsuki’s mating gland.
Katsuki lets out a low rumble, surprised at how good it feels to have the omegas in his arms, tucked safely in his den with him. Why hadn’t he done this before?
Everyone is quiet in the room and Katsuki reaches just above Eijirou’s shoulder on the wall and clicks the light off, already content with the fact that he’s going to have company for the night. He shuffles down over the pillow at his back and both omegas automatically follow his movements until they’re nestled into a puddle of warm bodies and tangled limbs over the bed.
It’s soothing, listening to the quiet purrs in the room and–
He jolts awake what feels like only seconds later to the muffled ringing of his phone. He pats around the covers which have somehow magically been pulled over them and the two bodies on either side of him wiggle when he touches over them. The phone keeps ringing and he scrambles to try and find it before it fully wakes the two sleeping omegas. Suddenly, a brightly lit screen seems to appear out of nowhere as Eijirou hands him his phone. He snatches it up and glares at the time 1:32am… Who the fuck? He swipes up on the phone and sighs in acceptance when he sees who it is.
“You might as well come join us…” he greets, voice low and gritty from sleep.
There’s a gasp over the line. “I’m so sorry for waking you so late, Bakugou…I just really need–Wait, what do you mean come join you?” Kyouka asks quietly.
Katsuki sighs again. “Ei and Denks are already here. Just get your ass over here. The door is unlocked,” he grunts.
“Oh,” she says in surprise. There’s a few moments of silence, but then the door clicks open and Katsuki smirks in the dark. She’d already been outside his door. He presses to end the call and sits up a little more between Eijirou and Denki who are snoring lightly. Kyouka quietly closes the door and stands at the foot of the bed, her soft honeysuckle scent nervous and unsure. “I’m sorry–” she whispers.
“Don’t be sorry, Ears. Just c’mere,” he growls.
“It’s nice in here,” Denki suddenly murmurs from where he’s buried under the covers like a little burrito. “C’mon Kyo…”
“Are you sure, Bakugou? I’d hate to intrude,” she says softly.
Katsuki’s alpha itches with the adamant need to have all of the omegas snuggled around him in his den. “Get in here, Ears,” he encourages. Her scent flares with something surprised and pleased as she crawls up the bed, but hesitates as if she’s not sure where to go. Katsuki beckons her with his finger until she crawls up between his legs. When she settles back on her knees, he holds his hand out expectantly. She eyes him for a minute with a confused look but then she puts her hand in his. He turns it over and rubs his other wrist over hers. She lets out a soft gasp and the purr is instantaneous.
“Wow,” she whispers in amazement. Unable to help himself, Katsuki uses his grip on her hand to pull her forward until she collapses into a heap over his belly. He grabs the other side of the comforter and tugs it over her and lays back down, letting his hands tangle in her soft strands from where she nuzzles against his belly while purring happily. He drags his nails over her scalp while Denki and Ei suddenly cuddle closer to her and arms find tangle over her. Legs twist together until no one can tell where one of them begins and the other ends.
Pack… his alpha whispers, while Katsuki inhales their combined scents, huffing it like a drug, feeling possessive and protective of this new and foreign feeling swelling through him like a tidal wave. He feels like he’s exactly where he’s supposed to be for the first time in his life. He’s been fighting his instincts for years, hesitant to take on his role as Class A’s alpha…but if it feels like this all the time…He could see himself easily becoming addicted to it
