Life at UA was pretty good for Bakugo at the moment. He was doing fine in grades, his quirk was getting stronger, and to top it all off: he had three fantastic mates. Izuku, Denki, and Eijiro all had katsuki's scent on them so everyone knew that they were claimed and who they belonged to for the season. They were doing a great job at making it known too; they'd always politely turn someone down if someone wanted to mate and if bakugo called to them they'd go through great lengths to reach him.

As of right now, katsuki was laid back in class at his desk with a smirk on his face. He didn't think things could get any better than they already were. However, bakugo suddenly caught a snag of a scent so strong that it immediately caused his eyes to shoot wide open.

Without any warning or words, katsuki shot out of his seat causing it to fall back. Everyone in class 1-A turned and looked at him with confusion, but he wasn't focused on that at the moment. He tried to ignore all of his other senses and focus only on his smell. He stuck his nose in the air and did his best to see if he could find what he had just lost. Once he did he immediately started to head for the door. Of course, Denki, izuku, and eijiro got up and became curious and flustered.

"Kacchan! Where are you going?" Izuku asked as bakugo was walking past him. "Can I come?"

"Can I?!" Both kirishima and kaminari asked as well.

Katsuki quickly ran his hand threw izuku hair and shook his head. "No, I'll be back soon. Stay here, all of you." He stated and all three boys immediately sat down and watched katsuki leave.

Once outside the classroom, bakugo bolted down the halls. He used his nose to the best of his ability to see where the smell was coming from and better, WHO was causing it. Bakugo's mind started to race and think about all sorts of things when he realizd the smell was definitely was a pheromone that was out of control. That was probably why his body was starting to ache and he desperately wanted to mate right now. If he didn't find what who was causing this brilliant smell, he was going to lose it.

As he came down another hallway, he saw a couple of guys running past him. He realized that they were definitely alphas who had reacted to the smell and wanted to find the person releasing it. Katsuki rushed after them to make sure they didn't get to the person before he did. He followed the guys for a couple of minutes and noticed that the smell was becoming much stronger and it was making him beyond horny.

Soon, bakugo came upon a bathroom. He opened the door and the scent was heavy in the air. Not only that, but the room was packed with at least twenty guys and they were all yelling at this one stall that seemed to be locked. Once katsuki realized that the person behind all this must've been in there, he held up his hand and caused a mini explosion towards the wall, which caused all the males to become silent and turn to him.

"You all have thrity seconds to clear out of here before I wipe the floor with all of you." Bakugo growled and narrowed his eyes.

Immediately all of the guys grunted and sighed. They knew exactly who katsuki bakugo was and that he wasn't one to bluff. They hesitated for a moment but the minute bakugo gritted his teeth and stepped towards them, they made sure to quickly clear out within fifteen seconds. Soon enough, it was just him and whoever was behind that stall door.

Bakugo wasted no time. He walked over to the stall and banged on the door three times real loud. "Oi! Open up, your pheromones are spreading all throughout the school and I'm not letting anyone have you but me!"

At first it was silent but then the person spoked and they sounded truly surprised. "…Bakugo?"

Bakugo's eyes widened when he immediately recognized the voice. "Half-n-half?!"

"Tch!" Shouto sucked his teeth and remained silent, but katsuki couldn't help but grin.

"No way, you must be a fucking mess right now to be smelling that good," he stated and pressed himself closer to the stall door. "Say, can I fuck you?"

He listened for todoroki's response and only received a low growl back. "Leave me alone..none of you are going to get to me."

"Heh, you say that now, but no one's claiming you but me" bakugo stated and he was completely serious. "I know your hormones must be driving you insane so let me relieve you of the pain"

"No!" Todoroki snapped. "T-That's not what's gonna happen!"

"Please," katsuki stated and rolled his eyes. "You're practically begging someone to fuck you! I could've smelled you a mile away. You're doing a shitty job at pretending you don't need someone to fill that ass of yours."

"S-Shut up!" Todoroki stated and it sounded more like a moan, which made bakugo smirk. "You idiot, I do just fine with hiding my pheromones usually, it's just today I messed up a little and didn't prepare. But I have no intention of being someone's mate this year. I refuse to give myself to some stupid alpha, especially you! I'd DIE before I'd let you touch me!"

This caused katsuki smirk to disappear. Now he was more aggravated than anything else that shouto was making this so hard. Since, todoroki wasn't trying to admit that it was bakugo he needed, bakugo was gonna show him that it was him he wanted.

"Fine, I'll leave you alone." Katsuki stated and todoroki scoffed on the other side of the door. "BUT, I'm letting all of those fools back in."

Katsuki could hear todoroki shift in the stall. "Wait..w-what?" he asked.

"Think about it, all those horny fucks are probably out there somewhere still and if I go out there and tell them that I couldn't get to you, it'll be a full on dream come true for them. Seeing someone like you isn't already claimed, and seeing that I'm literally telling them that I won't defend you, they won't hesitate to come after you. And you know what? I bet it won't be only one guy who'll reach you, they'll all probably take turns, abusing your perfect body."

"That…That's not true.." shouto mumbled from the other side. He didn't sound as confident as he was before. "If you call them back in here I'll just kill them all!" He growled.

"No you won't. The way your body is now? You'll probably take down a couple of them but that's it, you'll be too weak to fight. Face it you know I'm right."

Todoroki went silent and katsuki realized that he had gotten to him. He smirked because he knew shouto wasn't dumb enough to allow that to happen to him. He clearly wasn't the type to want to be shared. "Well," katsuki stated and headed for the door. "I'll see you around half-n-half. I'll let all those alphas know you're ready for them."

"DON'T." Todoroki yelled and bakugo stopped. "And stop calling me half-n-half.."

Katsuki walked back to the stall and banged on it once more. "So what's it gonna be then, todoroki?"

Things went silent for a moment and then all bakugo could hear was the sound of the bathroom stall's lock being opened. He grinned before he pushed it open. There, was shouto todoroki who was sitting on the seat. Katsuki was right, he really was a mess. Shouto was leaning his head against the stall wall and breathing hard. His pants were already off and he was just sitting there with one of his fingers in his own hole. Todoroki was a cat and a pretty cute one when he looked like this. As expected, one of his ears was white while the other was red and he had a lovely long white fluffy tail.

Todoroki looked up at bakugo and katsuki smirked as he closed and locked the door behind him. "Awe, such a sad kitty."

Shouto immediately narrowed his eyes, showed bakugo his claws, and hissed. He was not in the mood for stupid nicknames, but bakugo wasn't worried. He observed todoroki's nails before scoffing. "Mine are bigger." He stated and approached shouto.

"Stay…Stay away from me," he stated.

"It's too late for you to change your mind." Katsuki grabbed todoroki's hand removed his fingers from himself. He then quickly slid in two of his own. "I've already decided that you're mine."

Shouto immediately sat up straight and arched his back. "Gah! A-ah!" He cried as he felt the fingers move inside of him.

"I'm guessing when you said you weren't prepared to hide your pheromones, you meant you didn't get to touch yourself." Katsuki grinned and shouto lowered his head to hide his face. "Admit it, you thought you were going to be able to get through this season without being marked if you fucked yourself right? What did you use, a dildo? I bet you choke yourself too, or maybe you like pain?"

Todoroki's face reddened deeper and he did his best not to make eye contact with the male in front of him. However, katsuki got tired of being ignored; he grabbed shouto by the jaw and made him look at him as he added an extra finger inside of him. "Nngh! MMnn!"

"Tell me! You fuck yourself right?" katsuki repeated and shouto slowly nodded. "I knew it, I knew you wanted something to fill you that bad."

"A-ah.. just..just shut up," todoroki stated and tried his best to glare at katsuki. "You stupid alpha!"

"Man, you must've had a shitty partner last year, huh?" Bakugo removed his fingers from shouto and removed his pants. "It must've been really bad sex or he just fucking sucked didn't he? You hate alphas so bad, but I'll show you how I'm different from your last mate."

Without another word, bakugo slid into todoroki slowly but constant. The further bakugo went, the wider shouto's eyes became until he was yelling when katsuki reached his limit. "W-Wait!" todoroki begged and bakugo listened but he smirked in todoroki's face and began to swirl inside him, causing shouto's toes to curl.

"I bet I'm penetrating you deeper than any toy you used could've done, I see it in your fucking eyes!" he stated before he pulled out and thrusted back into todoroki.

"AAH! Aa-aah, aahnn!" Shouto stuck out his tongue and began to drool. Katsuki saw that shouto's tip was red and he was going to come at any second. He quickly wrapped his hand around shouto's member and began to stroke it. Todoroki tried covering his mouth to hide his whimpers as he came in bakugo's hand.

This didn't stop bakugo from continuing. He picked up shouto and pushed him against the stall wall. Bakugo began to thrust faster and harder into shouto and the other male wrapped his legs around him. "Haa-aah!"

Bakugo continued his pace and squeezed onto shouto's wrist, burning them a bit. He didn't give todoroki a single moment to get his thoughts together and pretty soon shouto came again. "Haa, aah o-okay k-katsuki, I think I get your point" he managed to say as he panted.

"You don't." bakugo stated with a serious expression and shouto gave him a shocked one. "And I'm not done teaching you yet."

Katsuki carried shouto over and sat on the stall's seat so that he was sitting on his lap facing him. Katsuki lifted up shouto's ass and positioned his member to slid in once more, but todoroki protested. "N-Not like this! That's embarrassing!"

"Then you should've thought of that before you decided to think you know everything." Bakugo stated and smirked as he lowered shouto onto him. Todoroki immediately arched his back and his eyes widened. He couldn't believe he still felt this good.

But katsuki didn't move and todoroki looked at him with disappointment and confusion. "You do it." he stated and todoroki's face reddened even more. He closed his eyes and held his shirt in his mouth as he moved himself up and brought himself back down hard onto bakugo.

As shouto continued his actions, he couldn't help but feel closer and closer to katsuki than ever before. Of course he'd never tell him that but he started to wonder what would happen after all of this.

"Listen to me," Katsuki stated and grabbed todoroki's hip, causing the other male to break from his thoughts. Suddenly, bakugo began to ram into shouto twice as hard as the speed shouto was going. He threw his head back and yelled in unbelievable pleasure. "I don't give a fuck if you hate every alpha on this planet, but you're not gonna hate me. You belong to me now and you won't let ANYONE touch you half-n-half or I'll destroy you. I'll treat you good as long as you be good. You got that, shouto?"

"Y-Yes, I understand." Shouto stated and leaned down. He licked katsuki gently up his neck. Once he was done, katsuki quickly pulled him back and kissed him hard. As he did so, he dug his nails into todoroki and came.

"Mm!" Todoroki broke the kiss as he felt the liquid enter him. "Aaah-ah! S-Shit!"

"You feel that? Get used to it because I'm gonna be cumming in you whenever the fuck I want."

"Haa, O-kay, a-ah!" Shouto managed to speak as he came for the third time.

After a couple of minutes both boys exited the bathroom stall. Bakugo with a grin on his face and shouto with his regular stern look, they both went towards the sink to wash there hands.

"By the way you're tighter than I thought you were gonna be." Bakugo stated and smirked as he washed his hands.

Todoroki splashed him with water and turned red once more. "Stop talking…And don't say things like 'you'll take care of me'."

"But I am gonna take care of you, you're my mate and that's my job." Bakugo stated with no signs of joking in his voice.

"…You don't know anything about me." Shouto mumbled and he was unaware of how close katsuki was to him.

"Then I'll get to know you," Bakugo stated in todoroki's ear and quickly bit him hard on his neck. "Now stop making excuses, let's go."

"Ow," Shouto reached his hand up and felt the bite mark before he looked at katsuki. "Go where?"

"You're apart of our group now," katsuki grinned and held the door open for him.

Bakugo walked ahead of todoroki as they exited the building after school. Shouto still wasn't sure what he was suppose to be apart of but once he saw the three waiting outside for katsuki, he knew what it meant. Denki, eijiro, and izuku immediately ran up to katsuki and rubbed off on him. From the distance, todoroki could see him telling them something and he wondered what it was because they looked so interested.

Katsuki then pointed at shouto, which threw him off. His eyes went wide as all three of the males came charging at him and they almost knocked him over to hug him the same way they did to katsuki. They all seemed so happy that todoroki was one of them, and he couldn't help but notice they all smelled the same and like him too. Shouto soon smiled, realizing that this wouldn't be a bad season after all.

All five males walked away from the school and towards katsuki's house together.
