I went to an open campus of an esthetics school where you can experience a real school before enrolling, and I was the only guy there! What's more, the training was touching the girls' bodies with just a towel! My crotch was touched all over... and I got a full erection! During the training, I was only covered with a towel, so the towel shifted and the girls' breasts and butts were visible! When I was being treated, they treated me in my most sensitive areas, so I couldn't help but get a full erection! As expected, I thought they would find out and get angry, but they didn't want to do the training, so they used my dick...
