Let's pretend that you're lying on your stomach on a massage table I'm standing with my swollen self directly in front of your face. My hands are oiled and I'm taking nice long movement of my hands down your spine. From your neck to your ass and back up again. You've been given orders.
Do not move, or touch, my goods voluntarily. As I love my hands down your back I have to bend and reaaaaach causing my dick and my balls to rub against your face. The full length of me just pressed against your cheek, running back and forth against it, getting harder and harder. I start reaching further and begin massaging your ass, squeezing and releasing all the tension from the long day.
