The doctor quickly hit the emergency call button on Bakugo's bed with his free hand. Mitsuki and Masaru jumped, and looked at each other in alarm. Kirishima positioned himself between Bakugo and the doctor, keeping eyes locked onto the calm older man. A moment later a couple of nurses rushed into the room and froze when they saw the glaring alpha holding the doctor's wrist. The air was thick with the scent of aggression.
Kirishima's shirt brushed against the bedrails and the angry pheromones blasting off the alpha made Bakugo's heart race in his chest. A tremor started in his core, snaking its way down his arms. "Kirishima," he panted and reached out, curling a trembling fist into the back of Kirishima's shirt.
He looked over his shoulder at Bakugo and, when the smell of fear finally registered, the anger melted from his face. He let go of the doctor's wrist to reach out to Bakugo, his eyes wide with concern. The doctor rushed to the nurses, murmuring something to them that couldn't quite reach his ears, and one of them rushed out of the room.
Kirishima gently cupped Bakugo's cheek and a warm, soothing scent enveloped him. Somewhere in the back of his mind he realized that this was an alpha's comfort scent, the scent alphas gave off to distressed mates. He'd smelled it in the past, but it felt completely different smelling it now. When you were an alpha and you smelled other alpha pheromones they only registered dimly, as if from a distance. Now the smell was everything, it was bright and high-def. Fucking technicolor when he'd lived his whole life in black and white. It was amazing and terrifying at the same time.
The pheromones rolling off Kirishima right now were the only thing that mattered for several glorious minutes and all he knew was pleasure. But as the fear subsided Bakugo found that it wasn't enough. The fire still burned under his skin.
More.
He realized he said the word out loud when Kirishima's eyes lit up with an electric intensity. He drew closer and Kirishima's natural scent mixed in with the pheromones. Sweat and deodorant and all things masculine.
Kirishima's eyelids were heavy over eyes that glowed with lust. As his head lowered Bakugo found his limbs limp as he waited and some part of his mind howled with outrage. This wasn't him. He wasn't the type to just let things happen to him. He wasn't the type of person to let himself be kissed. But still he waited, his breath quickening in anticipation.
Instead of being kissed, though, Kirishima rubbed his warm cheek against Bakugo's cheek, like a cat marking his territory. Stubble rasped against stubble. Bakugo sighed, feeling an odd mix of relief and satisfaction. Kirishima nuzzled his face, brushing his lips across Bakugo's cheek, following his jawline to his ear, and earning a shocked gasp from the blonde man as lips touched his ear. Razor sharp teeth grazed his sensitive earlobe and Bakugo grabbed a fistful of Kirishima's red hair. A low growl rumbled from Kirishima and his face lowered still. Lips traveled across the pulse point just below his ear, kissing the frantic beats. Kissing turned into licking, slow and deliberate licks that spoke of the delight only an alpha could feel from tasting his mate for the first time.
Bakugo tightened his grip in Kirishima's hair but couldn't make himself pull his head away. He panted helplessly into Kirishima's red hair. Kirishima attempted to lean harder into Bakugo, but paused and ripped his lips away for a dizzying moment. He huffed in frustration at the bedrail for daring to come between them and ripped it off the bed in one quick, jarring movement. Then he swept Bakugo into his arms, his face buried in the crook of Bakugo's neck. His breath came out in bursts as his rubbed his nose against the new omega's scent gland, invisible to the naked eye but all-consuming to the alpha.
Bakugo's heart leapt as he felt the sharp, pinprick tips of Kirishima's teeth brush over his neck. It was as if someone dumped a bucket of ice water over him and the gravity of the situation hit home.
"Kirishima!" he murmured, his voice felt rusty in his throat. "Wait!"
"Mine," Kirishima breathed against his neck. "Mine."
Just when Bakugo had given up all hope of resistance, the nurse that ran out earlier flew back in the room with a security guard in tow. The sound of a loud bang echoed across the room and Kirishima instantly slumped against Bakugo's chest. The noise rang in Bakugo's ears as he stared down at the unconscious alpha in shock.
Grief clawed its way from the pit of his stomach and into his chest. He shook Kirishima only to get no response. The pain in his heart increased until he doubled over on top of him, shaking uncontrollably. He buried his face in Kirishima's hair, hiding the streams of tears making tracks down his face that he could barely feel.
The doctor sighed. "Finally. Get the alpha out of here immediately."
The security guard, who easily had to be 7 feet tall, walked toward the bed. Bakugo's grip on Kirishima tightened and he looked up to snarl at the guard, his eyes unfocused and wild with fury. The guard took an instinctive step backwards.
"Easy now, Bakugo. The alpha is fine, he was just shot with a sedative. He can come see you again when he's slept off the pheromones," the doctor explained.
Somewhere in his mind Bakugo understood what the doctor was saying but his emotions were wild with anger and black with loss. He glared at the doctor and his hands smoked warningly, starting to burn Kirishima's shirt. The doctor gave the guard a meaningful nod and before Bakugo had time to react, the guard raised his tranquilizer gun. Bakugo heard the bang for the second time and sank into blackness once again.
********
When Bakugo woke for the second time he felt even worse.
He barely felt the cuts all over his body, and scarcely registered his injured foot. He writhed on the bed clutching his abdomen, practically delirious from need. What he needed, in his fevered mind, he couldn't even fathom. He dimly felt wet all over, from pheromone-pungent sweat and fluid that just continuously leaked between his legs. Slick. It was eroticized so much among alphas, and even betas, although they were barely affected by it, that slick-related products were a multimillion-dollar industry. Imitation slick sold like hotcakes, by many brands and in countless of varieties of scents and tastes. Real slick was less than glamourous, though. Take the sensation of peeing yourself, add the viscosity of oil, his concentrated scent, and there you go. When the ache abated briefly, he felt uncomfortable and gross, mostly.
Masturbation didn't seem to help very much, if at all. But he couldn't resist doing it. Anything for relief. Before he realized what he was doing, he found his hand curled around his cock, pumping it furiously. He lost count of how many times he'd cum but his dick was staring to feel raw and sore.
When he untangled his legs from his bedsheets and stood up for the first time in hours his legs buckled underneath him like a newborn deer, sending him face-first onto the tiled floor. His nose started to bleed from the impact and he wiped the blood away quickly, frustration making him want to cry. He clenched his fists and sucked in the surge of emotion in horror.
Over his dead fucking body would he cry. Not about this. This was just a mistake. Quirks were strange and unpredictable but, generally speaking, they almost never lasted forever. Sooner or later he'd return to being an alpha and put this nightmare behind him.
He remembered Kirishima's reaction and blushed. He raised his legs to lean his head against his knees bracingly, taking a few calming, meditative breaths. That was a mistake, too. Pheromones just confused and instinctively reacting to each other. Once he was back to normal Kirishima would be the same old Kirishima..... Right? Fucking hell, he better be. Bakugo would bury the memories of Kirishima licking his neck and looking at him like a treat waiting to be devoured in the deepest part of his heart.
He doubled over clutching himself and dry-heaving, as the pain spiked abruptly. Slick poured from him and pooled on the hospital floor. When the wave of agony subsided Bakugo pulled himself out of the liquid and slowly rose back to his feet. He wobbled to the door of his room, opened it, and peeked his head out.
Scents assaulted him. He immediately knew that the nurse at the desk nearby was an omega. She smelled quite mild to him now. He could barely pick out her scent among all the other pheromones, which was kind of comforting. The older smells of alphas and betas drifted throughout the hall but they seemed faint, like no one other than the omega nurse had walked the hall in hours. It was unnervingly quiet.
The nurse looked up suddenly. Whether she smelled him, or if she just sensed being watched, he wasn't sure. She strode over to him quickly. "Hi, I'm Nurse Lucy. I'm glad that you're feeling well enough to get up but you really shouldn't push yourself. Rest up, I'm sure you're feeling terrible still," she said sympathetically. "Do you need anything?"
He paused, taken a bit aback by the gentle way she spoke to him. He was used to omegas treating him with the caution and anxiety you would treat a feral beast. "A clean gown and bed sheets. Ice water."
"Of course. Right away!" She smiled at him. "I'll grab you a heat pad too for the cramping. I swear by them!"
He looked away, feeling awkward, and peered down the empty hall. "Where is everyone?"
The nurse's smile stiffened. "Well, it would be better if the doctor explained it to you... I believe he's heading here soon...."
"What happened?" he demanded.
"We had to evacuate most of the patients out of this hall. It's your heat pheromones. They are something else." She shook her head in amazement. "The rooms are supposed to be scent proof but somehow there's still some leaking through. It was driving everyone crazy. Alphas were being driven into rut left and right, eventually even the betas started to feel affected, though to a much less degree, of course. Only Omegas are allowed in this hall for now."
Bakugo's face felt hot as he blushed again. He never felt so embarrassed in his whole life. Everyone knew what was going on in his room right now. The slick, the jerking off... All of it.
"I'll go get everything now but please stay in your room," the nurse begged. "It's not much, but it helps with your pheromones a little bit."
He nodded and retreated back into the room, closing the door behind him mechanically. He sat down heavily on the hospital bed, which now felt cold and wet. It felt like sitting on a bench soaked with rain. A few minutes later the nurse returned with the things he requested and the heat pad. He changed in the adjoining bathroom, wiping his body down with a washcloth. When he came out feeling a lot better, she was throwing the soiled bedding in a plastic bag. She added his gown and washcloth to the bad and knotted it tightly.
She noticed him watching her and she smiled wryly. "Don't worry, these will be thrown into the basement incinerator."
"What?" It seemed a little extreme.
"You know, or else someone could snatch then up and do who knows what with them. Next thing you know there's a Bakugo-scented faux-slick being sold in every sex shop. The slick of the number 2 hero in the world would sell like crazy. I've heard that Midoriya has armed guards monitoring his trash."
His jaw dropped. "That's a thing that happens?"
She arched a brow at him. "Where do you think the scents being sold come from? They don't just come from people's imagination." Bakugo was horrified. It was a blatant invasion of people's privacy. How was something like this legal?
Somewhere an alarm chimed. "Oh! That's the doctor!" She rushed out of the room to let the doctor into the hall. The doctor entered his room wearing a heavy-duty respirator on his face. Shame made him look away from the man.
"Hi Bakugo, I'm not sure how your memory is right now, but I'm Dr. Tanaka. I see you're feeling a bit better." He voice was a bit deeper than Bakugo remembered and he shifted uncomfortably on the bed.
"It comes and goes, so let's make this quick," he snapped.
"Yes, that's a good idea. Well, as you may have guessed, this is your first heat as an omega. The woman who did this to you hasn't been found yet but I hear several heroes are searching for her as we speak. In the meantime, we still don't know much about what exactly this quirk is. Your pheromones are, honestly, more powerful than I've ever encountered. We think that this might be due to the fact that you've never actually experienced a heat before. Imagine a dam filling up with water, the water constantly growing higher until a catastrophe hits and the damn breaks. It's a rather fascinating theory my colleagues and I have been developing. Honestly, your case could overturn many currently held ideas about secondary genders on their heads." His voice was raising with excitement.
"Gee, that's fucking fabulous," Bakugo sneered. "When am I going to go back to normal?"
Dr. Tanaka slumped a little in disappointment at Bakugo's lack of enthusiasm. "We're not sure. Without finding the omega, we can't say for certain. If I were you though, I'd prepare yourself for a long-term life adjustment. Speaking of, I've been in contact with your parents off and on all day. They say they're at your house right now, making it a bit more suitable for you. Regrettably, we can't have you remain here for your entire heat cycle. We desperately need the beds so we're going to have you go home as soon as possible, hopefully in a matter of hours. If you need anything though I'm going to give you my personal cell phone number. If anything new happens, or if you are worried about anything, I want to hear about it immediately."
A loud repetitive buzz rattled from the doctors back pocket and he pulled out a two-way radio. He pressed a button on the side of it and spoke into it. "Is it him again?"
Bakugo couldn't quite catch the response to the question. Dr. Tanaka sighed wearily. "We've already tranquilized him three times now. I really can't give you permission to do it a fourth time without putting his health at risk." Bakugo felt his bed tremble slightly and the doctor frowned at the shaking floor. "Call the Hero Public Safety Commission before he starts tearing the lobby apart."
Kirishima.
Bakugo's heart leapt into his throat and he could feel the heat just under his skin build again. His vision flickered as Dr. Tanaka looked at him uneasily and slipped the radio back into his pocket. "I don't think I can stay any longer, even with the respirator, I'm sorry. Your parents should be here soon, though. Your alpha is something else. I've never seen an alpha so persistent but don't worry. I'm sure the Commission will take care of everything."
As the doctor left, with his remaining strength Bakugo snarled, "He's not MY alpha."
