Nick has been booked as the subject of a life drawing class but when he turns up there are only girls in the class and the female teacher instructs him they wish to draw him with a hard on so they can study shadows for their art project. He isn't sure at first as it a very unusual request but the teacher talks him into masturbating in front of them to get an erection. She then talks to the giggling students about his penis and the way the light falls before asking them all up to have a closer look! She even smacks his cock with her ruler when it starts to lose its hardness, instructing him to "keep it up!".
