The neighbors in our exchange dorm were 4 huge South American guys. The room was so tiny and crammed, the beds occupied 85% of the space (they also had a tiny living room with a kitchen). They still got it going on with so goddamn many girls from the dorm. I think each one of them had another girl every night. How did they do it, I don't know.

Just 3? Make it 4-8 with bunk beds in a room so tiny where literally the only free space is to stand in and walk to the end of the room and nothing else.

I mean, they've spent the last 3+ years being horny all the time and now they're away from their parents and unsupervised...

Yeah, that's the hard to believe part here. A professor having sex with a student is believable. A professor having their photo taken while they're in bed with a student by that student's roommate and while they're in the university's dorm? That's a lot harder to believe.
