He is gonna tease you

The hand on your thigh stopps as does the other and then nothing. Your breathing was coming thick and fast, and the master behind you pressed close, and you felt his cock rest between your buttock. You are very aware of the massive amount of heat that his cock gaves off, you can feel it twitch and rub against your ass, and you also feel his hot breath on your neck.

All of a sudden you feel the tip of his thumb stroke the bottom of your scrotum and you gasp invouluntaily, he does it again and then again. The hand them moves up and you groan as he cups your balls in his hand and lets them rest there.
