On his first day of figure drawing at art school, an adult student discovers that the nude models are his own classmates. To keep the model from feeling singled out, the instructor orders everyone to strip, leaving him as the only naked man among the women. His erection is impossible to hide. Paired poses require him to touch the nude women while they handle his crotch, making him fully hard. The assignment escalates into intensely entwined poses meant to show moving bones and muscles, creating such a charged atmosphere that even the teacher becomes visibly aroused, though the scene stops at the brink of penetration.
