A few years ago I read a story that centered around 2 girls in highschool when was a bully that was being abused at home by her stepfather the other one was a latina that lived with her father and brothers who own and or ran a martial arts studio
They get together because the bully thought the Latina was "mean mugging" her (but really had a crush on her) and kinda rapes the Latina in the locker room after the Latina proves she could have stopped it whenever she wanted
I'm not sure if I read it here or somewhere else
