My groin twitches from the estim pulse and a big dildo in my ass. Hands free orgasm.

My balls and dick are bound tight with a leather harness and silicone bands, and the estim is pumping and precum starts to drip. My entire groins jumps to the beat, and a prostate dildo moves around in my ass. After a quick check and reposition, I push it back in and turn up the power. It's set on a fast pulse, and soon it's off to the races, until my prostate pushes me into a head throbbing orgasm.
