At the esthetics school, I was the only guy! During the practice, I got to touch the girls' bodies covered only by a towel! My cock got so hard from all the touching! Since they were only covered by a towel, their breasts and asses kept showing! Even when I was getting a treatment, they touched me in sensitive spots, making me involuntarily erect! I thought I'd get caught and scolded, but it turned out they were all frustrated from dorm life and ended up giving me a full release until my balls were empty...
