Just a shower thought:
Triggers: incest, voyeurism, manipulation
Imagine being Shinsou Hitoshi’s older sister, putting him through the hero course, making sure he’s eating right, it’s only been the two of you for so long. She became a stripper to support him, he pretends that he doesn’t know but he does. He knows when you come home tired in the middle of the night where you’ve been. He’s seen you dance, in fact he’s even gone with Aizawa. He just had to show off his beautiful big sister.. So him and Aizawa make a plan to bring into Aizawa’s office. Of course you come in all worried about your little brother, and of course you recognize this man from the club, but your little brother comes first. What you don’t know is your little brother is right outside the door using his quirk so his favorite teacher can rail you while he watches. And course Aizawa will let his favorite student have a turn to indulge the forbidden fruit he’s always wanted.
What they don’t know is Hitoshi’s quirk doesn’t work on you for very long. Being his sister has it’s perks, you’ve seen them together at your club, you’ve seen how Hitoshi looks at you. You’ve been wanting it too, slowly baiting both of them. And finally now you have both of them, you just pray this won’t be the last time..
