Nude sketch models take turns on stage! Are all the other people besides the models nude? HUNTC-337

I entered the art school and found I was the only boy in my class! During class, nude models shamelessly paired men and women, and the nude women were touched! My genitals were also touched, and I got an erection! Furthermore, the models were required to express the movement of bones and muscles, and the whole class was asked to sketch them! In this situation, penetration wouldn't be surprising! The classroom atmosphere was bizarre; all sense of shame in art had vanished—it was too erotic! Even the teacher was breathing heavily, clearly aroused! It was truly outrageous!
