Bakugo was usually great at finding the perfect mates. He picked the same ones each year and it always turned out great for them. Everyone knew that he was experienced with mating and he was the best of the best in his class. Another thing about katsuki was that he assumed who was the best mates at times, but little did he know how that mistake could end up making him miss out on certain ones.

He was walking down the hallway with the rest of the UA students who were trying to get to class. Everything was normal, but then his nose went off and he was on high alert once again. Someone was definitely in heat but they were trying to disguise it. Bakugo looked around and tried to spot anyone who was acting funny but he didn't see anything off. He noticed his usually classmates, like Tenya, Uraraka, Mineta, Kaminari, and Sato, but nothing out of the ordinary with any of them. Pretty soon the hallways were cleared out and so was the hidden scent. Bakugo gave up and moved to his next class.

Layer that day, bakugo had smelled it again. This time I was really aggravating him because he was becoming hornier and hornier smelling it and he could tell other alphas were too. He looked around his class and nothing out of the ordinary was happening. Izuku was speaking with sero and Kaminari, Mineta was checking out jiro and ashido and everyone else was just being everyone. How was it that no one wanted to get to the bottom of that smell but him?

During the last period of the day, it was when bakugo had figured it out.

Everyone was outside getting ready to run some obstacle course but bakugo was frustrated and he knew he wasn't going to do well because he was beyond turned on from that same smell that was in the air. It was definitely a pheromone because it was always released when he was around other people. The only thing was he didn't know exactly who it was coming from because no one showed clear signs of struggling controlling themselves and there need to mate.

The obstacle course was a speed one, so it was clear tenya would be winning this one but everyone still had to see where they fell into place. As the event began, a bunch of classmates had started to run by bakugo and he had let them. He wanted to see if the person who smelled so good was going to pass him and sure enough, they did. A specific energetic moron had passed him with full speed yelling something, but all bakugo caught was a sniff off him. It was like a zesty smell that sent bolts throughout your body and made you want to mount someone so bad.

Bakugo was more than please when he found out who had been messing with his head all day. He was definitely going to get to the bottom of it before anyone else thought about it.

Later in the boys locker room, bakugo searched around for a specific person. The locker room didn't have many guys in it, which meant most of them had gone home to take there showers there, but the ones that were here were mostly hanging out together. All except for that one person, and it was most likely because he didn't want them smelling him.

Soon, bakugo found him. Kaminari was sitting alone and humming a song to himself as he put on a new set of clothes. It didn't take him long to notice bakugo, but he did his best to keep it cool like he was all day. "Hey katsuki! I was just getting ready to go so you-"

"It's you."

Denki looked up at bakugo with wide eyes but he hoped it wasn't what he thought. "H-Huh? What do you mean bud?"

"It's you isn't it?" Bakugo repeated himself and walked closer towards the other male. "The one who's been trying to hide his lightening smelling pheromones all damn day?"

Kaminari sat still for a moment but then he exhaled and turned back to his locker to get dressed. "Yea, it's me…sorry I didn't think anyone would notice if I hid them well and didn't show much of an reaction."

Bakugo stepped closer and he noticed that denki was no longer hiding his scent. Soon the locker room filled with kaminari's beautiful smell but luckily for him everyone had already taken there leave.

As katsuki gotten closer, kaminari seemed to be oblivious to him. "Why did you try hiding it?"

"It's…it's complicated katsuki, maybe there's something wrong with me or something but…actually nevermind it's not impor-"

Kaminari stopped talking when he felt bakugo's presence behind him. Suddenly katsuki was at denki's neck from behind and it made him blush from how close he was. "You've gotta be fucking kidding me, to hide a scent like this?! You're slower than I thought you were."

"Gee, t-thanks" denki stated and he closed his locker and zipped up his bag. Kaminari was a fox that was more golden than orange. At the moment, his ears were lowered and he had to wrap himself with his tail because he began to shudder being so close to someone as dominant as katsuki. "H-Hey katsuki? C-Could you like back up a bit, I think my body's reacting."

"So let it react" bakugo growled and he snaked his hands around kaminari's waist. Denki sealed his lips and did his best not to make and sounds but the minute he felt bakugo lick all the way up his neck he reacted.

"EEK!" He screamed and hopped out of bakugo's grasp and slammed himself onto the lockers. He took deep breaths and just stared back at the surprised and confused bakugo. He felt the blood rush to his face and he knew it was red from embarrassment. "Sorry! I told you, my situation is complicated.."

At first bakugo just stared up at the other male with a confused look, but once he pieced together what denki wasn't telling him his eyes grew wide. He formed a sinister smile on his face as he re-apporaoced denki, and it was clearly making him nervous.

"Denki," bakugo trapped kaminari in between himself and the lockers, and he gotten real close to his face. Kaminari had coward down and looked at bakugo with confused eyes. "It's clear that you haven't been marked yet, but have you've ever been marked..at all?"

Denki's ears shot up as his eyes went wide. Shortly he sighed and realized his secret was out. "N..No."

"That's fucking adorable!" Bakugo stated and started to immediately pinch at kaminari's nipples. He arched his back and his eyes went wide again.

"A-aah!" Kaminari's face was completely red at this point and bakugo didn't even have to do much to him, this was what he loved about unclaimed virgins, they were super sensitive. "I-I purposely try my best to hide my scent each year."

"Why?"

"B-Because I heard having sex hurts," kaminari said and closed his eyes. "But someone also told me it felt good, but I didn't know it felt this good"

"It can feel a whole lot better you know," bakugo whispered in denki's ear. "Let me be the first to show you."

"W-What?' denki opened one of his eyes to look at katsuki. "You m-mean like mark me?"

"Exactly," bakugo replied and then he released denki's chest. "But not here. Come on, get your stuff and let's go."

"So this is your room?" denki asked and looked around the medium sized room. He expected bakugo's room to be darker and full with explosives or something, but the room was actually really nice and tidy and actually quite similar to his. Denki immediately went around touching things, and katsuki rolled his eyes.

He had decided to bring him to his house so that he could take kaminari here. He had planned to take his time with this one and explain to him exactly what it means to be one of his mates. Even if kaminari decided to back out, it was a little too late for that now; bakugo had to keep himself calm the entire walk home because denki's pheromones were still heavy in the air and he didn't hide them anymore. He couldn't wait to make this boy his.

But then again, he remembered just how frustrating denki could be at times. He waited and watched the fox bounce around his room just touching things. He seemed to be having fun and he kept taking deep breaths to try and take in as much as bakugo's scent as he could.

"Oh cool!" kaminari yelled and ran towards a piece of katsuki's costume he was working on. Katsuki brought it home so that he could debate if there was anything he wanted to add on or change about it but that didn't stop denki from being fascinated by it. He observed it and spun it around at different angles with a smile on his face. However, the smile disappeared when something fell off of the piece of work. He realized he must've been playing with it too rough. "O-Oh, oops."

Bakugo rolled his eyes once more and approached kaminari from the back. Denki who was oblivious at first, froze when he felt katsuki's arm snake around his waist and his other rubbed his ear. Denki's breathing became heavier and heavier by the second.

"You like it?" bakugo asked. Denki didn't know if he was referring to the gadget he was just playing with or what he was doing to him now, but it didn't matter because the answers were the same.

"Y-Yess" denki's legs began to buckle and to make it worse bakugo brought one of his hands to denki's ass and squeezed.

Kaminari immediately gave out and katsuki released him, watching him fall to his knees. "It..It hurts" denki mumbled and he stuck out his tongue and began drooling. He was way too sensitive and katsuki loved it. He began to pull down his pants and boxers to reveal his already hard member; just seeing kaminari like this did things to him.

"I'll help you get rid of that pain, after you suck this." Bakugo growled and waited for kaminari to move.

The others eyes grew wide when he saw the size of katsuki. He was considering baking out but his body wouldn't let him think to far ahead. Kaminari crawled over to katsuki and opened his mouth. At first he just wrapped his tongue around bakugo's tip but then he slowly began to take him in the best he could.

Bakugo hissed and grabbed a handful of denki's hair. He was surprisingly good for a virgin and he seemed to enjoy using his tongue. "You're a virgin, but I bet you've sucked dick before with this slutty mouth of yours." Bakugo smirked down and kaminari's eyelids dropped as his face became redder.

He shook his head. "Gyou're muy firsth" he said with katsuki still in his mouth. It was like he did it on purpose to be cute and to send a vibration through bakugo's member. It made him even harder and aggressive at the same time.

Bakugo forced more of himself down kaminari's throat causing the other to choke for a moment with wide eyes. "I should cum down your throat right now," he stated before releasing denki. He gasped and fell backwards, panting heavily with his tongue out.

"But I want to cum in your ass today." Bakugo stated and got down on one knee. He reached for denki's shirt and tore it off of him, ruining it. He then quickly tore off his pants leaving denki in nothing but his underwear.

"Gah!" He yelped as bakugo stood up and dragged him by his leg to his bed. Once he flung him onto it, kaminari started to back away, frightened by the look on katsuki's face.

"Wait, wait, wait!" He shouted and held up his hands. "S-So once we do this…I'll be marked?"

"Yup."

"A-As in, no one else can touch me? I'll belong to you?"

"Exactly," katsuki reached and grabbed denki by the jaw before pulling his face real close and piercing into his soul. "And if you let anyone, ANYONE, touch you I will find you and kill you."

Denki nodded fiercely before bakugo let go of him. He pulled him closer by his leg again and ripped off his boxers, exposing him. Denki tried to cover himself but katsuki gave him a look that screamed 'Don't'. He left his hands over his face and hid in embarrassment.

"What'll..what'll happen to me once I become your mate?" he asked before katsuki shoved three of his fingers in his mouth. Denki was confused but he sucked them without complaint.

"Well, if you need me you're suppose to find me and I'll give you whatever you want. I'm basically in charge of you and you answer to no one but me." Bakugo removed his hands from kaminari's mouth and smirked at kaminari's entrance. "That also means whenever I snap my fingers you'll come running to me and if I want to I'll do whatever I want to your body and you'll love it."

Without another word, katsuki stuck one finger into kaminari quickly. Denki's eyes widened with shock and he arched his back. "AA-AH! Weird! It feels weird! Please, take it out!"

Instead of listening to his plea, bakugo wiggled the finger in him, making him squirm and shut his eyes. "You're so sensitive so it's gonna feel different for you." With that, he stuck another in him and kaminari moaned in pleasure and pain.

"O-Oh god!" kaminari shouted when he felt the third go in and bakugo started to open his fingers. He did his best to stretch him out and he practically started drooling feeling how tight denki was.

After a couple of minutes when he calmed down, bakugo flipped denki over so that he was on his knees and his ass was up to him. Kaminari didn't bother turning around, he panted heavily and waited for whatever was going to happen to happen. Bakugo chuckled and positioned himself right at his entrance.

"This is probably the hardest part, but just wait, I'll make you feel real fucking good."

"H-Huh?" Kaminari was about to turn but he froze when he felt something bigger enter him slowly. He covered his mouth and yelled into his hands.

"Fuck," bakug cursed as he entered denki. Once he was fully in he didn't move. He wasn't exactly trying to destroy denki's perfect insides just yet. "Denki, stop clenching for a fucking second, y-you're making me want to violate you."

Denki had heard bakugo's comment and he couldn't help but moan even though there was a majority of pain at the moment. "Too big…" he mumbled. "T-Too big!"

"Just wait I'll give you time to adjust but stop fucking clenching before I destroy you!" Bakugo growled. Denki did what he was told and did his best to calm down. As he relaxed, the pain slowly started to simmer down.

After a couple of minutes, denki had wiggled his hips and tried pushing himself back onto katsuki more. Katsuki grinned and watched kaminari do it. "S-So big ah aaah, it feels good katsuki."

"Heh, what a whore." Bakugo stated and slapped denki's ass. Without warning denki arched his back and came. Bakugo was delighted but he couldn't show him that, he wanted his mate to be well trained. He grabbed denki's hair and pulled him back to look at him. "Hey, I didn't give you permission to do that!"

Denki continued to push himself back onto bakugo, which meant he was someone who didn't mind extra rounds. "I-I'm sorry katsuki, it just felt so good! It still does, I want more, a-ah!"

"I'll give you more." Bakugo stated and released denki. He quickly grabbed onto the boys hips and started ramming himself into him.

"A-AAH!" Kaminari screamed and bakugo smirked. He was glad his parents weren't home because it sounded like denki was going to die. Kaminari literally began to claw at the sheets to get away but he was held in place. "N-No! Not that much more! Ah!"

"Don't run," katsuki commanded and grabbed onto the based of kaminari's tail to pull him back more. "Shut up and take it"

"Mmmmaaa, aah k-katsu-ah! Aa-aah," denki moaned louder and louder as he continued to claw at the sheets. He was extremely glad he chose to let bakugo do this to him.

Bakugo quickly pulled out to flip kaminari over on his back. When he slowly pushed himself back in, the slutty fox stuck his tongue out and arched even more. "I-It's so good!"

"Listen to me," bakugo demanded and waited for kaminari to look at him before speaking. "My scent is now imprinted on you so you belong to me. You will never even THINK about betraying me you understand?!"

Kaminari quickly nodded. "Y-Yes sir! Aah!"

"Based off your behavior, if you're bad," bakugo moved his head in the direction of the gadget kaminari was playing with and broke. When denki saw it he gulped and looked back at katsuki for mercy, but off course he wasn't going to get any. Bakugo grabbed both of denki's arms, pulled him close, and immediately started to ram his full length deep inside kaminari. Kaminari screamed and began to drool. He felt as if he was losing his mind as his eyes crossed and he uncontrollably moaned. When katsuki felt he had enough he stopped, and went at a steady pace again. "I'll punish you."

Kaminari couldn't even speak, his mind was scrambled and he was so close to coming again. "When you behave, you'll get rewards from me, you get it?" Katsuki asked and denki nodded while clenching up again. Katsuki was almost at his limit.

"C-Can.." denki struggled to finish his sentence but he knew he had to because he wasn't ready for another punishment. "Cannn, I-I-I come?"

Bakugo leaned down and stared daggers into kaminari's eyes. He saw that the boy wasn't filled with fear anymore, it was more like love for his new master. "You have permission." was all katsuki said before he bit down hard on denki's neck and came in him.

The feeling of the fluid filling his body pushed kaminari over. He yelled out in ecstasy as he came hard once more. Both boys laid there for a moment to catch there breath.

Soon, kaminari tapped bakugo. "Katsuki?"

"Yea" bakugo turned to look at denki and once he did denki had kissed him deeply. He broke the kiss and just stared at him for a moment before speaking.

"Thank you for being my first master," denki smiled warmly. "And by the way I can't move."

Katsuki was thrown off by how cute denki could actually be. He quickly snapped out of his trance and got up from his bed. "Fine I'll clean you, and I'm not only your first I'm your last idiot, you're mine."

Denki laughed and waited for bakugo to bring him to the bath to wash up, put on new pajamas, and sleep over.
