Mistress gemini is torturing this slave by turning his balls a painful blue. His balls have been locked up for days keeping him from being able to masturbate and now gemini has him tied down and is talking dirty to him as she runs her fingers along the shaft of his cock. She continues to fondle his cock until it is rock hard and then she smacks it and squeezes his balls to keep him from cuming. She plays with his nipples and has him squirming and bucking his hips to fuck the air. She uses a vibrator on the head of his cock and smacks it back down when she knows he is to excited so that the pressure in his testicles continues to build.
