Tightly bound cock estimmed hard for an orgasm.

Two silicone rings around each ball makes them swell and throb to the pulse of the estim current. My dick also is cinched with two rings and the power is coursing between my prostate and glans. My nipples are also wired... and my dick and groin start twitching. I crush my balls and turn up the power. Finally the pain is too much and I cum hard as my prostate gives up and flows.
