Estim from my ass to my dick and CBT bondage. HFO

There's an electrode in my ass, connected to an estim pad on the end of my dick. Estim pulses are surging back and forth through my prostate. My balls are also getting pounded by estim pulses and a bit of ball slapping. My groin is tightly bound with silicone and leather bands... but I manage to squeeze out a bit of cum.
