“Now put your cock between my feet. No tricks, honestly. Just do it.”
[You do as she asks and she begins to move her feet, gripping your cock nice and tight, working the shaft up and down, up and down]
“I bet you like that, don’t you? Your frustrated cock being pumped between my soles, my toes tickling your tied-up balls, faster and faster with a perfect shot at my perfect ass. I bet you’re dying to blow your load all over it, aren’t you?
“BUT DON’T YOU DARE CUM! If you dare allow yourself to explode, not only will I throw you out of here but I will punish your balls so badly that it’ll be the last time you ever do! And don’t expect me to slow down or stop just because you’re getting close.”
[Put a sock on your cock and stroke it for two minutes. Normal pace for the first, fast for the second. No stopping.]
