If there was one thing bakugo hated about school mornings it was taking the bus. Somedays he'd walk but other days he really was lazy and wanted to be in school as quick as possible just to end it as quickly as possible. Today was one of those days where katsuki just wanted the day to fly by quickly.

He got onto the bus and everything seemed to be fine for a while, but then there came a stop where a whole lot of people got on and it was a disaster. Katsuki was forced into a corner and he tried his best not to get angry enough to use his quirk. He didn't even have that many stops anyway, he'd be off pretty soon. He decided to close his eyes and wait for his stop to come up.

"Hey! Katsuki!" someone had shouted and it put katsuki on high alert. He quickly opened his eyes and scanned the bus to find the familiar voice. Soon, his eyes widened and then rested upon someone he actually didn't mind being around. "What's up buddy!" Kirishima shouted and smiled hard revealing his shark like teeth.

Kirishima, who was a kind of dog began to wag his tail and he had a hard time controlling it when he spotted his best friend. Katsuki sighed and waved back at his friend before turning away. He looked back at him three minutes later and noticed that he was still staring at him with a huge grin. "Stop staring riot!" katsuki growled and kirishima laughed.

"I can't help it!" He said and continued to laugh. But then he stopped. His eyes widened and he had a new look on his face that bakugo had never really seen before. Suddenly, katsuki noticed that there were more people on the bus and a couple of other teens had hoped on. They were awfully close to kirishima and it became clear what was happening. Kirishima must've been getting rubbed by one of the guys on purpose or by accident. Either way, it was really affecting him.

Bakugo noticed as more people loaded onto the bus, his friend was slowly starting to get sucked into the crowd away from him. Eijiro looked at bakugo with a red face and pleading eyes and this was something katsuki couldn't ignore. Quickly, he grabbed kirishima's hand and pulled him hard until he was right next to him in the corner.

"Stay here idiot." Katsuki said and made sure kirishima was close to him. Kirishima smiled softly and put his head down.

They stayed like that for a while, but then bakugo started to pick up on something. It was a scent that did not belong in a bus full of teens and it was way too sweet to ignore. He over and noticed kirishima was breathing heavy. "Eijiro?"

Kirishima looked up and his face was red and he was panting hard. Bakugo's eyes widened when he realized his friend was definitely in heat. "S-Sorry…" he said.

Katsuki looked over and saw that the other kids had smelled kirishima. They were searching for whoever was releasing there pheromones and bakugo wasn't going to let them find out just yet. He quickly switched places with kirishima so that his back was against the wall of the bus and bakugo was covering him up.

"What's wrong with you?" bakugo growled. "You can't release that sweet shit here are you trying to get raped?!"

Kirishima couldn't hold back the loose moan that escaped his mouth. "So s-sorry..i guess when I was stuck between those guys, they began rubbing against me without knowing and it started to feel…good."

"Hmph." Bakugo grunted and turned to the group of teens. He saw that they were trying to look over his shoulder to see eijiro so he covered him more.

"Is it that bad?" Kirishima asked panting and bakugo looked at him.

Kirishima's ears were lowered and his face was real red. His eyes were only open half way and he tried to keep his tail cupped between his legs. The site and smell of him made katsuki want to bounce and take him in front of everyone.

Bakugo ducked his head down into the nape of kirishima's neck. Eijiro closed his eyes and couldn't help but enjoy how close bakugo was. He tried his best to control himself but feeling katsuki's breath on him made him want to be touched. "W-What do I smell like?"

Bakugo took one last inhale of kirishima before he covered the boys mouth and bit down hard on his neck. Kirishima's eyes widened and he screamed into katsuki's hand. Katsuki raised his head and gave kirishima a wicked smile. "like a fucking whore."

Kirishima shivered and he couldn't control his urge to smile back. "Do I really?"

"Yup." Bakugo stated and trailed his hand up eijiro's shirt. He was surprised by how happy the boy was to be called such a dirty name. He must've been the type who liked it rough and mean. Katsuki knew he needed someone just like that. He flicked one of kirishima's nipples and he watched as his back arched.

Kirishima whimpered but refused to break eye contact. He bit his lip as he shivered and it was driving katsuki insane. Just as katsuki was going to try something else, the bus stopped and they were right in front of there school.

"Uuuuragh!" Katsuki growled as he released kirishima and hopped off the bus. Eijiro took a deep breath to try and calm himself down before he got off the bus with the rest of the students.

As he walked towards the school besides katsuki, he found it hard to smile because not only did he know he was sexually frustrated, so was his best friend. When they were only inches from the school doors, kirishima stopped walking and katsuki looked at him in confusion.

"Hey," Eijiro spoke with a slight blush still on his face. "Could you do me a favor?"

"Faster! Faster!" Kirishima sung as katsuki thrusted into him. "Oh god! There!"

Bakugo wasn't able to resist when kirishima asked him if he could mate with and mark him on the side of the school before the went into it. Kirishima wanted it bad and he felt the best person he could get it from was bakugo so he did. Katsuki was more than happy to mark kirishima. He didn't want anyone to have such a slutty character like him besides himself. It was amazing to him, to everyone, kirishima was this sweet mainly guy who was always calm and formal with most people. They wouldn't be able to believe the shit eijiro would say during sex.

"Katsuki! I wish I could have your babies!" Kirishima cried out as he stuck his tongue out and pushed himself back onto bakugo's member.

"I can't believe, my best friend's a slut" bakugo growled and he digged his nails into eijiro's ass.

"I'm only a slut for you! Now punish me like you hate me!" Kirishima yelled as his eyes rolled to the back of his head and he began to drool. "I'm not exactly mainly around you, my knees go weak and I just want to be penetrated all the time!"

"Shit, that's fucking hot" bakugo said and he grabbed a fist full of kirishima's hair and yanked his head back. He was doing him from the back on the side of the building that was closed off from most people, so they could be as loud as they wanted at the moment. That's why whenever bakugo rammed back into kirishima, he made sure it was hard enough for kirishima to yell and ask for mercy.

"Oh gooood," kirishima moaned and his knees started to shake. "I'm almost there katsuki! Come in me, I only want you to abuse my body whenever you're mad or in heat!"

Katsuki was on the verge of coming too, but he couldn't before his partner, so he lifted one of kirishima's legs up so that he could bury himself even deeper inside the male. Instantly, kirishima cried out as he came. Seconds later, bakugo followed and he made sure most of his seed was left inside of kirishima.

They collapsed on the floor and tried to catch there breaths. Kirishima went to his phone and looked in the camera. The bite mark that katsuki had placed on his on the bus was still there and it was real red.

"So I guess this means I'm a mate of yours?!" Kirishima asked excitedly and wagged his tail.

Katsuki grunted before pulling eijiro closer to him and kissing him. "With that tongue of yours, I wouldn't dream of giving you to anyone else."
