When I entered the esthetics school, I was the only guy there! During the training, we touch the body of a girl wearing only a towel! My crotch is touched all the time and gets fully erect! During the training, she was hiding her body with just a towel, so the girls' breasts and buttocks were all visible! Even when I am being treated, I can't help but get a full erection because the treatment goes to the most risqué areas! As expected, I thought that she would get scolded when she found out, but perhaps because she was frustrated by living in the dormitory, she made me detox until my balls were dry...
