Denki Kaminari x Bakugou's sister! Reader: a slight misunderstanding

It was early in the morning. You couldn't be bothered to get up yet, so you just rolled over, you face coming in contact with someone's chest. You're eyes opened to see who it was. Oh, it was only Denki. You'd forgot you'd let him stay over last night after you studied together. You wrapped an arm around him and cuddled close to him, feeling him do the same just a second later.

"Mornin' [N/N]." He said opening one eye to look at you still half asleep. He kissed your head, then your cheek, than your lips.
"Good morning, pikachu." You said and giggled, giving him a quick peck on the lips in return. "I don't wanna get up yet, let's just stay here a little longer." You said. Truth was, you just needed your cuddles. He chuckled, clearly knowing this, and hugged you tightly.
"Alright, we can stay like this for a little longer." He said.

Ahh, it was so peaceful and quiet, not to mention warm. Suddenly, you heard footsteps up the stairs. 'Oh, I forgot he got up before me. He won't come in here though, we're safe.' is what you thought to yourself before the door swung open, revealing your brother.

"Oi, shitty sister, I'm making pancakes for breakfast. Do you wa-" he paused and looked at you, then at Denki.
"Shit." You muttered under your breath. Katsuki had no idea Denki stayed round last night. In fact, he'd basically only just found out you guys were dating. You turned your head to look at him and he looked pissed.
"Morning, Katsu." You said and sweat dropped slightly.

"Don't you 'morning' me you little shit. What the fUcK IS HE DOING IN YOUR BED?!" He yelled. Thank god mom and dad were out and didn't hear that. You sat up and so did Denki.
"It's not what you think." You both say at the same time, but Katsuki didn't look convinced. You sighed.
"Look, we were studying until late last night and I insisted he stayed over night in stead of walking home on his own around midnight. He wouldn't let me sleep on the floor and I didn't want him to sleep on the floor. So we both slept in my bed. Nothing else happened. Alright?" You were too tired to deal with your brother's bullshit this morning.

"So nothing happened? You're still a virgin?"
"Yes. I'm definitely still a virgin." You said and Denki hugged you from behind.

"HANDS OFF OF HER BEFORE I BLOW YOUR FUCKING FACE OFF!!!" He yelled and you stood up, telling Denki to stay where he was, and walked up to Katsuki. Mini explosions crackled in your hands as you got closer.

"Are you forgetting I can defend myself if I need to? I can also beat the shit out of you for threatening my boyfriend." You said as you pointed your palm towards him.
"You're not allowed to use your quirk in the house." Katsuki said and you sighed, going back to Denki.
"We'll be down in a second. Make some extra pancakes for our guest."
"No." He said and you looked at him with the saddest puppy dog eyes you could. He sighed. "Fine, but not too many." He said before going back down stairs. You looked at Denki and smiled.

"I think that went pretty well. You got to live and he's making you pancakes." You said and Denki hugged you tightly.
"Let's just hope that I don't get killed for this later on." He said and laughed a little. Soon you two could smell pancakes, so you both stood up and walked downstairs.

"That was more than a second." Katsuki said before putting down two plates of pancakes on the table beside each other. "Just sit down and eat." He said, then sat down at the table after getting his plate. You and Denki both sat down. You both started to eat, then you hear Katsuki begin to speak.

"Look. While I'm not one hundred percent okay with you dating my sister, I trust you enough to believe you're not gonna hurt her. So I guess you're alright." He said. "Just know that if you do hurt her, you better watch your back. Got it?" He said and Denki nodded, smiling brightly.
"Thank you, Bakugou. Don't worry, I won't do a single thing to hurt her. I love her more than anything." He said and your brother just rolled his eyes, but you could tell he was happy for you.

I'd say this went great.
