Knowing how desperate slave gimpy is makes me all the more eager to torment him some more. His orgasm is right there -- it's clear by the way he shallowly breathes, trying to push it down so as not to cum without permission -- and I am having fun toying with his cock, seeing how close to the edge he can get. I give him tingles with light, gentle touches, only to overload him with full firm strokes. He doesn't know what to do except panic and grow harder. Is it time to cum yet?
