Trained and Humiliated With Estim on Bondage Chair

First, I ensure he is completely immobilized. Straps around his body, head, hands, and feet. My slave is completely at my mercy. After three days in the cock cage, his arousal is at its peak, but his release is not for his pleasure, but for mine. I make one thing clear to him: he belongs entirely to me for the next two nights.
Instead of stimulation, the electrode awaits. I send electricity through his cock and control the intensity with the push of a button. To increase the pressure, I clamp the control under his foot. As long as he has the strength to lift it, the pain remains bearable. But his muscles tremble, and soon, due to his own exhaustion, he shocks himself over and over again.
Later, I switch to my finger. Here, his self-control is put to the test. He must endure the pain and may only press the relief button on my command. If he fails, there is punishment. If he obeys, brief stimulation without release. In the end, I leave him alone in his restraints, while the current continues to hum quietly through his body.
