Chapter Text
"I hate it, but it's almost time for you to go Kats. Third years still have curfew checks, you know this." Katsumi groaned as she snuggled deeper into her boyfriend's embrace.
Katsumi whined, "I don't want to go."
She heard her boyfriend laugh and his laugh rumbled through his chest. "I know Kitty Kat, but unless we want a lot of questions, you gotta."
She rolled just enough to glare at her boyfriend. He was right, but that didn't mean she had to be happy about it. "We're eighteen. We shouldn't have a damn curfew." She had been glaring at him, but she kind of got distracted. Her boyfriend was pretty. He had the brightest blue eyes she had ever seen. He was lean and had light blonde hair that he had let grow shaggy in their third year.
She was dating the one and only Neito Monoma. Class 3B's residential shithead, Class 3A's bane of existence, and the boy she was currently in love with and had been for the last year and a half.
What started out to be a mutual hatred and rivalry in their first year turned out to be mutual attraction in their second. They clicked and they just worked together. He was a snarky shithead and she was a sassy asshole. They just worked.
Class 3B knew of their relationship, and the only ones of Class 3A that knew of their relationship was her best friend Kyouka Jirou and Neito's best friend Shinso. They just hadn't told the rest yet, well because her class really didn't like her boyfriend and she just didn't want people in her business. Neito had harassed her class for the last three years, and as nice as some of them were, they held grudges.
There was something else that she was hiding too, and that's that she's trans. Nobody except her parents, her boyfriend, Kendou, and Kyouka knew she was a girl.
Neito had taken the news well when she had told him before they started dating. She wanted him to know the real her. He happily accepted her and loved her for who she was. He had told her exactly, "Boy, girl, anything in between. I like you for you. I want to be with you for you."
The only reason Kendou knew was because she had accidentally walked in on Katsumi straddling Neito while she was in just her bra and panties. That had been an awkward conversation and she still hated thinking about it.
She knew most of her class and Class 3B wouldn't care that she was trans. She just didn't know how to go about telling them. Besides, it was her business. She wanted to be out, she did. She wanted to be herself, but, she was just scared. She was scared. Yaoyorozu had come out as a trans girl in their second year, and she was accepted, but she wasn't Yaoyorozu. She wasn't as nice and sweet and pretty. Yaoyorozu had been on hormones for years and everyone already knew her as her. Nobody knew of Katsumi yet. She was just Bakugou. She was the demon spawn of her class. Yeah, she luckily had some feminine features and she had mellowed out for the most part, but she was still herself. She was crude and still somewhat aggressive. She was scared no one would see her for her.
She groaned as she sat up. She pulled her hair up into a ponytail. She had been growing it out for the last two years. She stood up to grab her shirt and sweats. As she bent over to pick up her clothes, she heard Neito move and then she felt a smack on her panty clad ass. She clutched her clothes in one hand and put her other one on her hip as she turned to look at him. "Doing shit like that is not how you get me to leave. That's how we get in trouble."
He just a grinned a shit eating grin at her as he propped himself up on one of his elbows. "I can't help it, you're the one who bent over in front of me."
She rolled her eyes as she slid on her normal skull shirt over her pink tank top. "Yes, cause me bending over means you just have to smack my ass." She rolled her eyes again as she pulled on her sweats.
He chuckled. "My hands are tied. Rules are rules. I see you bent over, I spank you."
She finally broke and grinned at him. "Shithead."
He rolled out of bed and made his way over to her. "Asshole."
She ran a hand down his bare chest, "Yeah, but I'm yours."
He smirked and brought her into a kiss. "That you are, just like I'm yours."
She smiled into the kiss. Then he peppered her jaw with light kisses. She tilted her head to give him better access. "Neito, you keep that up, I'm not leaving." He continued to nibble on her jaw and down her neck. She flexed her hand and clenched it. "Mmm, N..Neito, honey, please."
He nuzzled into her neck and chuckled, "You know I have no problem with you staying here, but you just know people are going to ask questions. You not coming back on a school night? Your friends will freak out."
She sighed as his teasing came to an end, "Put on a shirt and walk me to the door, fucker."
He kissed her again, "Anything for my girl."
They walked down the halls and down to the common room. There were still some of 3B milling about, she waved at them as they walked by. The two of them stopped by the front door to the 3B dorms.
Neito pulled her into a kiss. It was a gentle goodnight kiss. "Message me when you get there."
She smiled and playfully rolled her eyes. "Neito, it's a three minute walk and I literally explode things with my hands." They both knew she still would message him.
He gently gripped her chin, "Still. Do it for me, please."
She nodded, "You know I will."
He kissed her one more time. "Good." He whispered to her. "I love you, my Katsumi."
She melted into him, "I love you too, Neito."
She had forgotten her coat up in his room. She watched as he grabbed one of his hoodies from a hook on the wall. It was a navy blue hoodie that he wore constantly. It was the one she stole most of the time anyway. She smiled as he slipped it on her. It smelled like him and that brought her comfort.
Katsumi waved to him and walked back towards Heights Alliance. It was a cold November night and it had started to snow. She messaged Neito as she walked up the steps of her dorm building. She walked inside and was instantly met with Iida's stern voice. "Bakugou. There's only thirty minutes left until curfew. You're really starting to cut it close."
She rolled her eyes. She was not in the mood for his shit. "You're not my damn dad. I was busy."
He softly grumbled from behind her, puzzlement clear in his voice. "When did you turn into a teenage girl?" Katsuki couldn't help but smirk to herself as she pretended not to hear him.
She walked through the common room. She nodded at Kyouka who knew where she was. Some of her other close friends were down in the common room too, like Eijirou and Mina. Eijirou looked at her, "Were you training? It's pretty late to be training bro. You got to take a break."
Katsumi shook her head as she walked through the common room. "I was just busy. Kyo knows where I go. I'm safe and that's all that matters. Everyone can stay out of my business."
Everyone turned to look at Kyouka. She just shrugged, "Kats is safe. Nobody needs to worry."
Uraraka popped up beside Iida. "We're just curious where you go Bakugou. You disappear at random times. Sometimes you're gone for the entire day after class."
Katsumi sighed. These fuckers weren't going to give up. "I have a boyfriend. That's all you fuckers are getting out of me."
An ear piercing squeal split the air. She turned to glare at Mina. "Pinky, what the hell?"
Mina just grinned, "You have a boyfriend? That's totes adorable! Who is it?"
Katsumi shook her head. "Nope. You're not getting anymore out of me."
Mina whined. "Bakuuu." She then turned towards Kyouka. "Jirou, do you know?"
Her best friend rolled her eyes, "Of course I know, and no I'm not telling you."
Before Mina could keep whining, Shinso walked into the room. "What's with all the squealing going on in here?"
Mina huffed. "Blasty has a boyfriend and he or Kyo won't tell us who it is."
Shinso just shrugged, "I know who it is too."
Mina looked stunned. She looked from Shinso back to her. "I can understand that Kyouka knows. You two are inseparable, but Shinso? You two barely talk. Why does he know and we don't?"
Katsumi dropped her head back and groaned. "The fucker just knows. It's not important. I just have a boyfriend. It's not national fucking news."
Eijirou gently smiled at her. "As long as he treats you right. That's all that matters."
She couldn't help but smile at the thought of Neito. Nobody treated her as well as he did. He treated her like a princess, and not in a condescending way either. "He treats me just fine."
She was getting done with this. She just wanted to call Neito before she went to bed. "This hasn't been fun. I'm going to bed." She nodded towards Kyo and just made her way out of the room. She liked being able to fall asleep to the sound of her boyfriend's voice.
Katsumi was sitting in homeroom the next morning. She was chatting with Kyouka when she heard a very familiar voice enter her class. "Hello, my darling class of losers."
Neito entered the room giggling. Almost the entire room groaned. Katsumi tried her best to repress a snort. Kyouka smirked at her and rolled her eyes. She whispered to her, "Your boyfriend is such a dick."
Katsumi was trying to hold in her giggles. "Yeah, I know."
Katsumi noticed Shinso wave at Neito from the back of the class and Denki pouted. Shinso and Denki were a couple but Denki still couldn't stand Neito being his boyfriend's best friend. It made her want to laugh. Denki rolled his eyes. "What are you doing here Monoma?"
Neito locked eyes with her for just a split second before a massive grin broke its way to his face. "I just had to stop by to see my favorite class and come see my favorite princess."
He smirked over at her and she had to work very hard at not smirking back. He called her princess because it was a way for him to affirm her identity, but he also got to seem like he was just being an asshole because nobody else but a very select few knew. He could call her miss and say she and her and nobody batted an eye because they all just thought he was being a dick. It was a fun little game they got to play.
The class groaned. Eijirou looked over at her. "Don't mind him, bro."
Mina huffed, "I'd rather Blasty beat the smirk off of his stupid face."
Neito tutted, "Now that's not very nice Class A. I was just coming to see how my favorite blonde was doing. Don't speak for her."
On the inside, Katsumi wanted to giggle, but she had a part to play. She snarled, "What do you want? Fucker."
She could see the absolute amusement dancing behind her boyfriend's blue eyes. "I want another shot at a sparring match. You may have won the last one, but you won't win this time."
A smirk made its way to her lips. Their "sparring" sessions usually consisted mainly of half assed play wrestling and making out when they had the gym to themselves. She clicked her tongue. "You're on shithead. I've beaten you every single time. This time will be no different."
A spark ignited behind his eyes. Neito grinned, "I believe I really won last time."
She wanted to bite her lip when she thought of what had transpired last time. What had started as play wrestling quickly escalated. It escalated to them running back his dorm and him making love to her for the first time. She stared back at him, "I definitely won."
He laughed. It wasn't his over the top laugh that he did to laugh at her class. It was his actual laugh. It was low and she loved laying her head on his chest so she could hear it rumble through him. "I guess our rematch will be the decision then."
Gods she wanted to do nothing more than walk over and kiss his stupid and pretty face.
The bell signaling class started in five minutes chimed overhead. Neito grinned, "I'll see you losers later. Especially you, princess."
With that he left and Katsumi had to work hard at hiding her smile. She absolutely loved that shithead.
After school was over, her and Kyouka made their way to the gym. Kyouka smirked at her, "Try not to get caught humping your boyfriend in the gym during your "sparring" session."
Katsumi felt her face heat up. "Shut up. We're just going to spar."
Kyouka rolled her eyes, "Sure you are."
The two of them walked to the gym where they found Neito standing there waiting. He smiled at them. Katsumi seen him check around before leaning in to capture her lips in a quick kiss. She happily hummed and smiled into the kiss. She would prefer the kiss to last longer, but they were in the hallway.
Kyouka just snorted. "I'll see you two later. I have a study date with Mo. Don't be too gross."
Katsumi put her hand on her hips, "You have no room to talk. If I remember correctly, you and Ponytail were almost caught fucking in the library just last week."
Her friend's face turned pink. "Shut the fuck up. I shouldn't have told you that."
Katsumi grinned from ear to ear. "I'm your best friend. We tell each other everything. Those are the rules."
The shorter girl rolled her eyes, her cheeks still pink. "Whatever. I'll talk to you later baby girl."
Katsumi waved. "Later babe."
Katsumi turned towards Neito who was grinning at her. "If I didn't know better, I'd be jealous. Baby girl? Babe? Sounds like things are serious between you two."
She snorted as the two of them walked in the gym hand in hand. "Yeah, because we both know Ponytail would be so happy sharing her with me. That girl is so protective of that short stack." She looked up at Neito. "Besides, you know you're the only sarcastic asshole for me."
Neito grinned, "Love you too, princess."
They began warming up, and as she stretching, she felt Neito come up behind her. He placed a hand on her hip, she thought he was going to be sweet, but he ended up just snapping the waistband of her panties against her skin.
She turned to face him and lightly shoved him back. "Fucking jerk."
He grinned as he slowly approached her. "I couldn't help it. Pink is just your color. So cute." That's when he went to tackle her and take her down.
She let a high pitched squeal of laughter out as he took her down. She let him pin her at the wrists as he straddled her waist. He grinned down at her. "Give up Kitty Kat."
She pretended to struggle. "Never."
He leaned down, keeping his lips just out of reach. The damn bastard. "Give. Up. Katsumi." With each word he would get close to kissing her but then he would pull back.
He held his lips just out of reach, even when she would raise her head to chase him.
They had the gym reserved for next thirty minutes so the last thing she was expecting was a slam of a door and a familiar voice calling out. "Katsuki!?"
