Yknow, sanemi being genya's teacher is enough for me to tell you that they fucked a lot and there's a shitton of teacher/student dynamic (the good stuff) but what if i told you that genya sucks off sanemi everytime before math lesson so he can get good grades,,,

I can just, FEEL the absloute slutry from genya when he wears lingiery under his uniform and when he gets close near sanemi when they're alone he streches his collar to show it off and keep walking past him while he tries to take in the view he just had and keeps staring at-

-genya's back until he dissapears from his sight and grunts from sheer horniness and can't wait to feast on him when they get back (or better yet, when the school is empty) BRUHUHUHUHUHUHHHH
