I was the only male student in the yoga trial class... The more I tried to avoid being mistaken for participating for erotic purposes, the more my dick reacted to the sight of the beautiful instructor's protruding buttocks... When the bulge in my lower abdomen was discovered, I decided to surrender myself to a group erotic lesson that was not included in the trial course...
