well, first time posting, some years ago, i remember reading a certain doujinshi that is serialized, but i can only remember that there's a guy that is a student(muscle guy), as his sister(that is smaller) that's a teacher, then i only remember a scene were his sister and another girl are being r**ed by a bunch of students, then she tries to send a mensage to her brother, the guys notice and take her phone, but was already sent, then imediatly her brother apears and beat the crap out everyone. i hope if anyone know the name?
