Chapter 2: Little Firecracker

Izuku stood in the practice field, speaking

with a couple of girls and Katsumi wasn't a huge fan of that. 'Fucking….talking to my De….Izuku…' she growled in her head.

She had been doing her best to suppress her possessiveness as hard as she could, but it was hard with Mina holding his bicep, and Momo would squeeze her arms together to push her bust out at him, even if it was unconscious.

Another thing that wasn't helping was the absolutely sinful way Izuku filled out his gym clothes, his muscular frame becoming accentuated by the clothes that were custom made for the first male student in UA history. No wonder Momo and Mina were all over him.

The only solace she got was the fearful and resentful looks that the blue haired bitch was shooting Izuku when she thought he wasn't watching.

"Alright Brats! This is the apprehension test! You, Mr. Popular! Get in the circle." Ms. Aizawa barked, looking like she was already tired of dealing with bullshit for the rest of her life.

Letting out a tired sigh,Izuku strode into the circle with careful, methodical steps. "OK, what next?" He asked in a bored tone. He had a guess what this was and he was already tired of the looks and whispers. 'Seriously, what the hell is that girl's problem with me.' He looked back at Aizawa who tossed him a Baseball.

"Use your quirk to throw the ball, as fast as you can." She said, giving Izuku a glare.

"Yes Ma'am." Izuku said as he took a deep death and lifted the ball with his quirk, but just as he was about to toss it he caught it out of the air as it started to fall. "Quirks allowed huh?" He said as he turned his head to look at the teacher. "I knew I recognized you, Eraserhead."

Aizawa glared at the male and clicked her tongue. "Give me one reason why I shouldn't expell you on the spot." She said as she stepped forward to almost get into his face, only to notice he was physically massive compared to her. Not that it mattered.

"Better yet. Give me one reason you should." Izuku said, his voice tight and his intense green eyes fixed on hers. She had to blink at some point. "So do you plan on sabotaging me the whole time or just now?" he asked when she didn't answer, a cold edge still present in his tone as he fixed a glare on the underground hero. Her eyes were getting dry, it seemed.

Aizawa knew she needed to defuse this and also save face, because she knew he could tear her limb for limb with his Quirk the second her's stopped affecting him.

"Try again. I won't stop you, problem child." She grumbled, waiting a second before blinking. She didn't know what he was going to do, but she was smart enough not to find out.

Izuku nodded and decided that he wasn't going to hold back. "If any of you can make a barrier to hold onto, I would suggest you do that now." Wait a few moments and seeing no one move he rolled his eyes and used his quirk to manipulate the pavement and make one for them. "You will thank me later." He said before holding the ball in his hand. After a few moments of calm and quiet the sound of something shattering the sound barrier was heard as Izuku sent the ball flying into the sky at mach three. The shockwave almost shattered the wall he made but thankfully it held true.

Aizawa watched with bated breath as the number climbed higher and higher on her display before it stopped all of a sudden, but the number displayed on her screen was oddly familiar. The barrier he made fell apart and fused perfectly where it came from as Izuku held the baseball up for her.

She turned and saw the hole in the building next to them and everything clicked for her. It had circled the globe.

"That good enough for you, Ms. Aizawa?" Izuku asked as he dropped the ball and walked back to the class, all of which looked like fish out of water. Katsumi blinked and looked down to make sure she hadn't soaked through her panties and her gym uniform.

"Th-tha-thats impossible! A man can't have that sort of power…it's just not scientifically possible!" The blue haired girl yelled as she saw the numbers on the screen.

"Forty million, seventy four thousand, two hundred seventy five meters!?!?" The class cried.

"Yes. It seems your classmate was able to send the ball all the way around the earth and back to his hand." Aizawa said as she tried to calm down. This man was a beast, he could kill them all on a whim if the mood struck him, and not even All Might herself could stop him.

"Midori? Don't take this as me sexualizing you or anything, but HOT DAMN WHY WAS THAT SO SEXY?" Mina said, stars in her eyes.

"I'll allow it." Izuku said with an amused smirk at the excited pink girl.

"Y-Yes, Mina is correct, that was… impressive." Momo said blushing again and unconsciously pushing her breasts out again.

"M-Ms. Aizawa? I need to go to the bathroom." Katsumi said with a heavy blush on her cheeks.

"You need to use the bathroom? Now? Can't it wait?" Aizawa asked, setting her monitor to have different settings.

"N-No. It can't. Please?" Katsumi said, her face burning as she made the request. Was it out of character for her to be meek and asking permission? Yes, but who didn't act a little differently with soaked panties?

"Fine. Anyone else?" Aizawa asked sarcastically.

"Well, now that you ask, I should probably go to the bathroom too." Izuku said, already having finished the first obstacle.

"Fine! Go then, and hurry back!" Aizawa snapped, causing them to both walk quickly to the bathroom, Katsumi's violent blush deepening rapidly.

As soon as they turned a corner, Katsumi felt her feet get held in place by what she immediately knew was Izuku's Quirk. 'Shit! I can't let him see me like this!' she thought as he walked around and looked at her flushed face.

"Are you okay, Kat? You look a little flushed." Izuku said with a teasing smirk.

For a moment, Katsumi considered lying, or even insulting Izuku to escape the situation before something occurred to her. 'Th-This is my chance to start winning him back.' she thought. "P-Please no teasing. I-I got a little… excited when you threw the ball and I was going to change."

Katsumi didn't notice when he set her free because he was walking closer and closer to her, closing the distance until they barely had an inch in between them.

"Poor little Katsumi, got all hot and bothered." Izuku teased as his childhood bully whimpered pitifully.

"I-Izu? W-What would it take for you to f-forgive me?" Katsumi asked, desperately wanting to be his girlfriend at that moment.

Izuku's teasing mood seemed to dim a little bit. "I-I don't know, Katsumi. I want to forgive you, but I don't know if I can yet. Do you have any ideas to fix how controlling you are?" Izuku asked. The main issue with her was the fact that she wanted to control him like she owned him. "I know deep down that you may still love me the way you used to, but I don't want a woman who will try to control me. I want someone who is my partner, not my boss."

"Wait! What if you were my boss?" Katsumi whisper-shouted as an idea popped into her head.

"... Okay, I'm going to need a little elaboration." Izuku said with a scrunched up brow.

"W-Well, I treated you like property, right? So to make it up to you, I became your property? I-I'm saying you would own me. Then I can't be controlling, right? Please? I just want my Izu back." Katsumi said, weirdly sad and aroused at the same time.

"... You have an ownership kink, don't you?" Izuku asked, an eyebrow raised.

"That-That is besides the point! I'm asking you to make me your slave, it doesn't matter what I like!" She said, her face even redder than before.

Izuku thought about her proposal for what felt like an eternity to her before he finally broke the silence. "I accept, but I have some rules." Izuku said.

"Yes! What are your rules, Master?" Katsumi asked, her panties getting ruined even more.

"One, you have to follow my orders immediately as long as they are reasonable. Two, you have to tell me if something is way outside your comfort zone, and finally, the safe word is Marshmello. Also, drop the master, just call me Izu. Or sir, I guess. It's cute when you're all submissive." Izuku said, gently caressing the side of her face with his thumb.

"Th-Thank you, Izu. I promise to be your good girl until we both decide I've paid my debt to you." Katsumi said, leaning into his hand and knowing that she might never admit she had paid her debt.

"That's my good Kacchan. Now, I've decided your first order is that you will wear your soaked panties until I tell you you can remove them. Understood?" Izuku said, tilting her head up to look at him.

"Yes sir." She said, her face burning. It was strangely hot that Izuku gave her this order, but her master had given her an order. "Thank you, Izu." She said as she stood up and looked at him.

"No problem my little firecracker, and one more thing." Izuku smiled and pulled Katsumi closer to him and pressed his lips to hers, his height and weight difference making it easy to man-handle her and dominate the kiss.

Katsumi moaned into the kiss and held onto Izu for dear life, not wanting to let him go after getting the one thing she had been craving all these years.

Pulling back and leaving a pouting Katsumi, Izuku smiled. "Let's get back to class, my little Firecracker." He gave her ass a slap with his quirk to get her on her way.

Jolting, She smiled and for the first time ever, giggled a bit at being treated like this. "Yes sir." She smiled and walked back to the field with Izuku in tow.

"Hey guys! As much as I liked seeing Izuku walking away, and then back towards me, he just had to bring the mean girl back too." Mina pouted, causing Katsumi to slip into her old habits. It was alright as long as her new owner wasn't the target of her aggressive behavior.

"Shut up you pink pervert!" She shouted as her hands sparked. That is, until she almost doubled over when Izuku let his Quirk brush against her soaked pussy to tease her. The message was clear: be a good girl.

The remaining tests weren't noteworthy as Izuku simply used his Quirk to make it laughable in terms of a challenge and they were all dismissed to their dorm rooms.

Katsumi followed Izuku to his, excited to see what would happen when her Izu had her all to himself.

"Take those dirty panties off." He said as soon as he shut the door behind them. He sighed and started removing his shirt, showing off the many years of work to the girl.

"Y…yes sir." She said blushing as the sight in front of her. "Izu? What are you planning to do with your new possession?" Katsumi asked, blushing as she pulled her panties down her legs and noticed they were almost completely soaking wet.

"Awe, my poor horny toy. I won't be doing anything but some not so innocent cuddling with you. Now I want you completely naked for me so I can tease you while we lay here." Izuku said, using his Quirk to strip her and lay her down while she smiled, liking the feeling of him effortlessly tossing her around his room.

Izuku got in the bed behind her as the big spoon, wrapping his arms around her, resting one hand on her pussy and the other on her sensitive breast, making her squirm and whine.

"You know, this all happened really quickly, didn't it, Kacchan?" Izuku said, nuzzling her neck and leaving tiny little bite marks.

"N-Not for me, Izu. I've been wanting this ever since I hit puberty." Katsumi sighed in content before tensing back up as he softly played with her beautiful body. "But until now it always seemed so outta reach. But I am glad you gave me this chance, Izu." She moaned softly as she nestled into his embrace until they both drifted off into oblivion.
