Mistress Vixen's obedient slave is placed into the ball crusher and treated to the ultimate pain and pleasure as she sits on his face whilst squeezing and squashing his most sensitive part. To further enhance the torment, she then attaches an electrical stimulator and proceeds to increase the current and make him squirm even more. His cock is not forgotten though, the sounds are used to full effect, Vixen showing her great skill and empathy, as usual.
