Red lace lingerie and BDSM... a smooth combination. Nipple are clamped hard. Balls and dick are tightly bound and wired with estim electrodes. A big butt plug is firmly lodged in my quivering ass. My dick is twitching even before I start beating it with a ball slapper. The harder I beat my cock and balls, the better it feels. Then, as the throbbing estim pulse crashes its way through my groin, I started massaging my balls hard. The power jumping between my balls turns into a swirl of extreme pain and extreme pleasure. Just as I start to cum, I yank off the nipple clamps and twist the pain into my nipples. Think I saw some stars as I convulse through another hands free orgasm.
