Fear and humiliation are my favorite tools to drill into the mind of my slave. Wearing a hot black pantyhose I slither on his tied up body and slide on his chest restraining his breathing. Ohh, poor thing is having trouble getting air. It seems to be even worse when I ride on his chest pressing the air out. I lift my legs to increase the weight even more. The longer I keep up the less air he is getting the hotter this gets me. I stroke his harnessed dick and balls with my pantyhosed feet while he struggles for oxygen. This is just after my liking.
