"Absolutely must not lay a hand on" For me, the teacher, that's a student. However, "the more taboo something is, the more exciting it gets." The forbidden fruit of "my pupil's G-cup and J-cup double Ds" made me lose my mind, crossing a line I shouldn't have, engaging in impure heterosexual intercourse! As a teacher, I did the unthinkable with a student in a threesome! My pubescent pupils fought over me, making me cum inside them multiple times... I've done something unforgivable...
