Giving up an intense orgasm with estim and ball torture

I've got my dick and balls tightly bound with a ballsplitter and silicone rings. I crop my balls and massage them while the estim pulses between them, banging back and forth until I see stars. My entire groin convulses as my balls twitch and quiver. It feels as if something is banging on my balls and they're banging back. The feeling of the shock wave is incredible. Finally, I get relief as I squeeze out some cum past the restraints.
