I'm in middle school (8th grade). Our teacher has a really big classroom. So apparently he was arranging my seat and unfortunately I sit all the way in the back with 3 guys... And one of the guys was jacking off... He kept staring at me until the period ends . When the bell rand I rushed outside and I couldn't get myself to stop imagining him doing it.. Should I tell my teacher about this???? Or should I just forget about it?? Like nothing happened
