The principal wants to talk with you personally.

As you file into the office the principal makes your sister wait on a chair in a waiting room. and leads you into her personal office. She yanks a seat out from in front of your desk and wordlessly ushers you to sit down. She then goes and sits behind her desk and just stares at you. The room smells of old paper and feels not cold but chilled. You look at the principal a woman you know who is in her 60's, but aside from the gray of her hair actually looks as young as your sister. Except her face is not that of a dumb slut it is that of a stern well composed woman.

She slides open a drawer on her desk which cuts through the silence in the cramped windowless room. She takes out a phone and fiddles with it before sliding it across her desk to you. Tapping it with a well manicured hand to play a video for you. What you see is your sister sucking on your dick taking breaks for air and to personally break up with several different boys by name. She clears her throat and you look up the sound of your sister slurping and sucking on your cock as background noise. She stares at you dead in the eyes and says "So do you care to explain why a video of two siblings having sex was sent to several students? A video which has already begun circulating its way around my school? Also what exactly you think I should do in this scenario?" She stares at you waiting for a response.
