Bakugou X Kirishima's sister (Reader)

Chapter 17

"What happened to you last night?" Jirou asked you as she applied a face mask.

You had spent most of your Saturday in your room, lounging the day away, until Jirou messaged you for a girl's night. The two of you watched movies, snacked, and were now partaking in some selfcare. You had spent the entirety of last night with Bakugou and you hadn't noticed until you got back that Mina had been trying to invite you to hang with the girls.

"Mina was texting you all night, she even went to your door, thinking you were ignoring her."

You couldn't help but laugh, you didn't mean to ignore Mina you were just a bit preoccupied. You'd put a headband on, picked a green colored face mask and began applying it before you gave her an answer.

"I was just... busy." You didn't really know what to tell her. You didn't want to lie but you'd also asked Bakugou to keep what was going on a secret, that meant you needed to as well.

"Busy with Bakugou?" she gave you a knowing smile.

Well, it's not like you told her, she guessed, what was the harm, right?

"Actually, yes." You were hesitant to say the words, but part of you was glad that you both could talk about this. It was a little nerve-racking keeping this to your self all the time.

Her face turned to one of surprise, "No way, you never brought up what happened with you both, I was just guessing. What did you guys do?"

"Well," suddenly a hard knock came from your door. "Hold that thought." You got up, making your way to your door, figuring it was your brother or Mina you swung the door open. "What do you want?" Your mouth fell slightly open in surprise as Bakugou stood on the other side of the door. He was wearing his usual muscle tank and shorts. Your eyes couldn't help but wander over him. He looked down at you, his face completely blank.

"Hot," was all he said, referring to your face mask.

You could feel your face heat up and if the mask hadn't hidden your face you were sure it would be red.

"Why are you here?" you questioned, collecting yourself.

He pushed passed you, walking into your room. "Did I leave one of my textbooks here the other day?" Freezing in his tracks he noticed Jirou sitting on your floor.

She glanced up at him, "Uh, sup?"

Not giving her a response, he simply turned to look at you. "So, uh, have you seen my book or not?"

"I'm afraid I haven't." you said trying to hide your smile.

"Uh, right." He left without another word, turning down the hall to go back to wherever he had come from. You closed the door and turned to face Jirou, but you couldn't quite look her in her eyes.

"A lost textbook huh? And why would his book be in your room?" You could hear the grin in her voice. At least you could blame Bakugou for Jirou knowing, even though you had already spilled before he came to your room.

"You know, I'm not sure. Maybe he was lost?" you avoided her question.

She gave you a look, "Come on now, you said you'd tell me." With a deep breath you filled her in on everything since your last talk. Finally telling her why you didn't hang out with them last night, that Katsuki had taken you to his place of peace. "That sounds creepy, he took you out into the middle of the woods. And wouldn't tell you where you were going?"

You couldn't hold back the laugh when you saw her expression. "Trust me, I thought the same thing, but I trust him, and it was actually really nice."
