When zayda walks in she wants to know how long serf has been in his cock cage as she places biting nipple clamps onto him. He winces in pain and tells her it has been a week. Serf is sitting in a chair naked with his hands in latex mitts that prevent their use. Electrodes are attached to his exposed cock. In front of him are pictures of zayda. She begins duct taping him to the chair as she tells him she is going to let him play with his cock today. After she gets him taped to the chair she makes him a duct tape condom and then tapes his mouth shut. She stands back and tells him, "go ahead, jerk off as much as you want." he takes his cock between his two useless hands and starts to jerk it best he can. He has to press it hard between his latex encased fists and move them up and down the duct tape condom. He tries hard. He tries to go faster. Zayda warns him that she has plans for his cum so he had better have an orgasm. As he squeezes, presses, rotates and strokes it she picks up the tens unit attached to his cock and balls. Zayda tells him that he jerks off like a retard while laughing in his face. She then turns the tens unit on and begins to shock his junk. As soon as he feels the electricity he lurches forward still trying to jerk-off. She turns it up again and he starts to whimper as she continues laughing at him. When she turns it up again he immediately stops masturbating and his arms flail about. When she warns him she needs that cum he knows it isn't going to happen. He tries again to masturbate, his entire body convulsing and releasing. He appears to have the worst case of parkinson disease ever seen. Even his screams are halting and filled with fear and pain. He's on a roller coaster ride of terror. She continues turning the power up until he is a babbling idiot that cannot even keep the spit in his mouth at this point. Zayda has a big smile on her face as he pleads and begs her to stop. She simply slaps him in the face and yells at him to "shut up!!" his day has just started.
