Beating the cum out of my balls while I electrify my dick

My balls are bound together and stretched tight with a thick two inch wide silicone band. Not much cum will squeeze past that. The ball slapper hits both balls at the same time. My balls are wired directly to my dick and estim current is pulsing up and down the shaft. My dick is tired and soft after a long edging session, but it's now time to finish it off. As I turn the power on again, my cock starts twitching almost before I can feel it. A steady throb intensifies to an involuntary twitch...The pulse hits my groin and I start hitting my ballsack with the slapper. The estim is pushing my balls to cum, but the slapper is driving the train now. I turn the power up past the boiling point to a hands free orgasm while keep hitting my balls. When I'm cumming and my balls are bound up this tight, just tapping on them sends a shockwave through my groin. A good hands free estim orgasm can rock your world... Just enjoy the ride.
