It was 4 AM in the UA dorms when Bakugo woke up. He usually slept fine, but tonight he was woken up by his burning dry throat and a pounding headache. He didn't think much of it and headed to the shared kitchen to get a glass of water. Bakugo would've been concerned about these things being a sign of heat if he hadn't taken his suppressants. But he has. Obviously. But, as he reached for a cup in one of the cupboards, his knees buckled and fell with a loud thud.
"Fuck." Was all he could manage. He was too tired to be explosively angry.
Bakugo thought back to what his mother told him when he was younger. About how, even if an Omega takes their suppressants, an Alpha who is truly made for them will set off their heat. But Bakugo hadn't been in contact with any Alphas?
"Tape-elbow's is a beta...Pikachu is an omega... Deku's an omega... who the fuck is it?" He thought to himself as he lifted himself off the floor. Bakugo gripped the counter and tried not to fall, but he could feel himself losing to his heat.
While Bakugo focused on trying not to completely fall into heat, Kirishima walked into the kitchen, looking for a late-night snack. The fiery redhead noticed the spectacle that was the muttering and slipping Bakugo and immediately went to his side.
"Hey Bakubro, what's wrong?" He asked quietly while trying to hold up the ash blonde.
"N-nothing, let g-go of me before I burn you, shitty hair." He replied weakly, too tired to make a heartfelt threat. He didn't physically try to move away either, at this point he didn't want to.
"C'mon, you need a little help right now. Do you want me to walk you to your dorm?" Bakugo thought about his offer and after some slight hesitation, he nodded and let go of the counter that was supporting him before.
Kirishima wrapped his arm around Bakugo's waist and pulled Bakugo's arm around his neck, so they could walk side by side. The blonde shivered at the physical contact and wondered back to why his heat is starting.
"Who are all the Alphas in our class?" He asked, he knows that he has only come into contact with his classmates recently.
"I think it's just me, why?" Bakugo stopped dead in his tracks at this statement and looked into Kirishima's ruby red eyes.
"I think I'm going into heat." Kirishima looked surprised, but he still held onto Bakugo's side.
"You're an Omega?"
"Yeah."
"And you don't take suppressants?"
"I take suppressants, dumbass. That's the problem." Bakugo looked away from Kirishima's sharp eyes and to the ground.
"Well, who's the Alpha that set it off?" Kirishima was well aware of the story that parents tell their Omega and Alpha children.
There was a short silence, filled with nervousness and worry. Kirishima rubbed circles into the Omega's side, which actually seemed to calm him.
"You." Bakugo's voice was barely a whisper and he still refused to make eye contact with the redhead that was holding him.
A wave of heat hit Bakugo and he nearly fell to the ground if it wasn't for Kirishima's help. He whimpered at the aching in his stomach and the overwhelming feeling of being empty. He felt slick start to drip out of his shorts and down his legs. The room felt terribly and uncomfortably hot. His clothes felt scratchy and constricting. Kirishima picked up the shivering blonde like a bride and carried him to Kirishima's room.
"Hey, are you okay? Bakugo?" The Omega nodded at his questions, even though he knew he wasn't okay.
"A-Alpha" He whimpered out, taking in Kirishima's scent. All common sense was thrown out the window. All he wanted right now was his Alpha.
Kirishima looked surprised, he's never really seen Bakugo in any way besides angry. But right now, shivering in Kirishima's arms, nuzzling his face in Kirishima's neck, he looked so small and almost cute.
Kirishima was snapped out of his thoughts by the overwhelming sickeningly sweet scent that Bakugo produced. It made him want more of the boy in his arms. It made him want to mate him.
The pair finally reached Kirishima's dorm room and the redhead let them in. He laid Bakugo down on his bed and sat next to him. He tried to resist the overwhelming urge to claim the breathtaking boy bedside him.
"Alpha, p-please." Bakugo whimpered out, "Need you."
"Are you sure? I don't want to take advantage of you during your he-" Bakugo pulled Kirishima down by his collar and smashed their lips together. Kirishima hesitated before kissing back, moving their lips together in a heated dance. Bakugo turned his head to deepen the kiss and Kirishima licked his bottom lip, asking for entrance into the Omega's mouth. Bakugo immediately complied, letting the Alpha explore his mouth, making him writhe and whimper. But, Bakugo grew impatient and pulled Kirishima on top of him and pulled at the hem of the Alpha's shirt.
"Are you sure you want this?" Kirishima asked cautiously.
"I-I've wanted t-this for a long time, Kirishima." His voice was shaky and small but filled with lust.
