Big vibrator in my ass helps me with another estim hands free orgasm.

I've got a huge loud vibrating butt plug in my ass. Both balls are bound tightly with a half dozen silicone bands, and my cock is connected to an estim sleeve. I start out slapping my balls a bit and turn up the power. My cock starts twitching. The vibrator gets louder as it tries to find just the right spot. I hit my balls harder, making them swell up tighter. I keep slapping until my balls finally give up a hands free orgasm.
