Pronouns : she/her
Being the younger sister of Nemuri Kayama, you were expected to be just as scandalous and flirtatious. It was something you always anticipated being brought up whenever you were on dates or among other heroes. Unlike your sister, though, you were a bit more conservative than she was, not willing to show so much of your body off like that. Your quirk wasn't as strong or as cool as your sister's in your opinion. Your quirk was one not seen; you could transform sound frequencies into light on command. It was hard to control for louder and higher noises, so you avoided President Mic at all costs.
Despite your reluctance to be in the same building as President Mic, you were constantly bringing your sister lunch after school was over (to avoid the loud man of course). She loved your cooking after all. So, here you were, lunches in hand while heading to the break room where she usually was at this time, waiting for you. However, when you entered the room, it was empty. How strange. You didn't want to risk a run-in with the megaphone of a man so you decided to ask someone to help you find her. The perfect person came to your mind instantly, Aizawa, aka Eraser Head. You liked him because he was quiet most of the time and he was so very nice to you. When you entered his classroom, you were surprised to find him sitting at his desk, instead of in his sleeping bag.
"Oh, it's you, y/n." He looked up at you. You always hated seeing his scar because it reminded you of his brush with death as well as your inability to help. You wanted nothing more than to be a hero like your sister but what good did bursts of light do?
"Have you seen Midnight? I have our lunches but I couldn't find her and I don't want to..." You trail off, feeling mean for saying anything about President Mic's voice.
"Have your ears be destroyed by that big mouth?" He finished for you, a small smile on his lips.
"Yeah." You sheepishly nodded your head.
"She left early today, something about an interview." He looked off absentmindedly.
"I forgot that was today." You cringed at your oblivious mistake.
"You said you brought lunches?" He asked, tilting his head to look at the bag in your hand.
"Yeah, but I suppose it doesn't matter now." You muttered sadly.
"Well don't let them go to waste, I like lunch." He stood up and walked towards you. He had always been taller than you; everyone was.
"Oh! Why don't we eat them together?" You suggested despite him already implying this.
"Works for me... Although I haven't worked up an appetite-- well not for food at least." He looked down on you, brushing your hair behind your ear. Your face instantly flushed and your heart pounded. You began to stutter, trying to think of something to say.
"Compared to that promiscuous sister of yours, you're so different-- vanilla even." He muttered, his confident smirk making your stomach do flips.
"I-I'm not vanilla." You argued as best as one could while stuttering.
"Really? I don't think so." He grabbed the bag from your hand and took it over to his desk.
"You... You... You're wrong." You crossed your arms over your chest, feeling vulnerable from his words.
"Oh? Wanna prove me wrong or are you just going to stand there pouting because I'm right?" He teased. This was what you loved about him and why you connected with him better than other heroes-- he was comfortable around you and was different from his normal attitude. He had fun around you.
Living in your sister's shadow was no fun at all, you were always expected to be exactly like her or not like her at all. You had your obvious similarities but the differences were notable as well.
"You don't know as much about me as you think you do." You walked over, pushing the food away from him as you leaned over him since he was seated. His eyes darted down to your exposed cleavage now completely visible. At this, your breath quickened. He licked his lips before speaking again.
"I think I know enough, after all, you're so easy to read." He shrugged slightly.
"How? Show me how." You demanded. He smirked before sighing out deeply.
"Fuck it." He muttered before grabbing your face to press his lips onto yours.
You quickly melted into the kiss and pressed deeper into him. His hands went down to your hips as he pulled you in between him and his desk. The cold wood of the desk was on your ass and the warmth of his lips and hands were contradicting the feeling. He stood to his full height, breaking away from the kiss momentarily. He pressed you further onto the desk, your back being forced onto the cold surface. You arch it in an attempt to get away from it, but his body is over yours, keeping you down.
"Aizawa," You stutter as he looks down at you, licking his lips hungrily.
"Is this not vanilla enough for you?" He mocked.
"If anything it's too vanilla." You bit your lip after the words left your mouth. He chuckled, his chest shaking and you felt the vibrations through the desk.
"Well it's a good thing this desk is solid oak and the classroom is soundproof. Let's see just how vanilla the infamous y/n is." His eyes darkened with desire as yours widened slightly.
Midnight's dozens of calls all went to voicemail on your cell, which made her worry about you. However, when she got home and found you flushed in the face with the scent of lust on you, she no longer worried for you. She worried for who had gotten that far with you. What nobody knew was that her little sister was the freakiest person she knew, you were just picky with choosing your partners.
