I enrolled in a vocational school aiming to become a sports instructor. But I was the only guy there! The lectures were fine, but the practical training was like a godsend with girls in tight clothes that showed off their body lines! This is bad! I got hard from being so close to the girls in their sexy clothes! I thought they would get angry, but the frustrated girls were so curious that they trained with my dick. To be honest, it was too erotic and I couldn't concentrate on the practical training!
