Mistress Serena’s pain slut has already been reprogrammed to get turned on and only orgasm whilst in extreme pain, but she has decided to up the ante on his pain thresholds in this session. The slave’s balls are sandwiched in the crushing plate and every now and then the pressure increased with a gentle yet cruel twist of the fly screws. His anal passage is filled with a humiliating plug and his nipples, not to be neglected are viciously clamped too. The ordeal really starts to test him when Mistress uses her stiletto heeled boots to jab at his most sensitive parts, but his immobility through bondage means he can do nothing but take the pain of her desire. Finally, his humiliation and this next stage of Mistress Serena’s mindfuck training is accomplished when the intensity of his suffering triggers an orgasm, right into his face and open mouth.
