I'm not even a substitute and I've been asked to take care of an injured track and field team member and give him a massage. At first I was reluctant, wondering why I had to do it, but as I was asked to give massages every day, I got better at it! What's more, I couldn't resist touching the sexy buttocks of girls covered in sweat... Of course I got a huge erection! Just when I thought it was dangerous, she started to fidget when I touched her... It seemed like something was going to happen! When I casually touched her private parts, she started to feel it! Once it started, there was no stopping it!
