I was in my last year of HS. The year when you realize how much the school really sucks and really messy stuff about the administration gets to your ears, the school was in a though spot to be honest. Anyway. I had this new physics teacher who was a pretty cool guy, and fun to be around(Though I liked the one that left best). Some of my classmates and me would talk to him when he was on guard duty during breaks and everything. I always thought he had a flirtatious personality, but I ignored it 'cause I had this idealized idea of all my teachers.
One day, the principal comes to our classroom to tell us that the teacher had to take a leave because of an scholarship, and that we would have to change teachers again in the same year. It sounded pretty fishy.
Turns out, 7th, 8th, 9th,10th and 11th graders have been trying to seduce the guy for months. He eventually fucked some of his 7th and 8th grade students and one of 'em got pregnant (This last part is not confirmed)
I have even more stories. A friend of mine was fucking the principal. And the principal was using the school founds to pay for his rather expensive car to take her out.
And that's as far as confirmed info goes. There's also circumstantial evidence (Testimonies) of a classmate of mine banging the new geometry teacher (Who had a wife and children) in a car on front of a bar.
