Bakugou X Kirishima's sister (Reader)

Chapter 22

You had told Katsuki that you wanted to go to the beach this morning before he left your room. It wasn't summer yet so it wouldn't be packed full of people, but it was also warm enough to go in the water. Considering you hadn't been to the beach in a long time you knew that's where you wanted to go. Katsuki had told you to meet him outside the dorms when you were ready. After finding your favorite swimsuit, you put on a tank top and a scarf like, flowy, wrap around skirt that showed off your legs nicely.

When you were finally ready you made your way downstairs and outside to find Katsuki waiting for you by the steps. He was scrolling on his phone not really paying attention.

"Ready to go?" you asked excitedly as you walked up to his side.

He glanced up at you, his eyes taking in what you were wearing and instantly his face turned to a look a disapproval.

"Go change."

You scoffed at him, "Katsuki, we're going to the beach, what I'm wearing is fine."

He stood up straighter and looked down at you with a glare. Crossing your arms, you matched his demeanor, not backing down. The two of you stayed like that for a few moments, realizing you weren't going to change your mind he rolled his eyes.

"Tch, whatever," he turned to leave, "But you're not leaving my side," you heard him mutter as he began walking towards the campus gates. You couldn't help but smile to yourself as you followed after him.

You both had been walking for a bit, the beach wasn't that far from the school. You were almost there when Katsuki glanced down at you, "You know your hair really makes you stand out, what happened to that disguise you were talking about, miss undercover."

"You think I forgot?" you questioned him with a laugh. Reaching into your bag you pulled out sunglasses that were so big they about covered half of your face. Right after you pulled out a hat big enough to hide you from the sun.

You grinned up at him, he had his fist covering his mouth like he was trying to stifle a laugh, "I think that makes you stand out just a bit more."

"I may standout, but they have no clue who I am." You chuckled as you both made your way onto the sandy shore.

You began to search the beach for a spot, Katsuki close beside you, glaring at anybody and everybody who walked by. Walking away from the large group of people, you found a more secluded spot farther away from the shops and restaurants on the boardwalk. With an umbrella behind you, to hide you further from prying eyes, you sat down letting the sun warm your skin. Katsuki joined you, his leg nearly overlapping yours as if daring someone to get any closer to you. Lowering your sunglasses, you looked up at him, he was frowning and looked all around unhappy to be there.

"You know, most people go to the beach to relax but you look more tense then before we got here." His grimace deepened at your words. "Come on, Katsuki, this is probably the last time we can have fun before finals." You knew he would never admit it, but it was his jealousy that made him act this way, the last few days had proven that. When he didn't respond you spoke again, "There's no need to be jealous."

He turned his head from you, "I'm not jealous, why would I be?" he grumbled.

Grabbing his chin, you forced him to look at you, "You know I'm here with you Katsuki." His face instantly turning a rosy tint at how close your face was to his.

"I- well obviously dumbass," he ripped his chin out of your hands, once again turning his face from you but for an entirely different reason this time.

With a smirk you continued to tease him, "Are you hot? Your face looks a bit red." He kept his head turned away from you. "We can get some smoothies; you know to cool you off?" you bit your lip to hold back your laugh.
