TopGrl Sister Dee’s nipples are on fire. clamped with TENS nipple clamps with the unit on a low tingle. she is pole bound, her pussy riding a metal bar. She is given a set amount of time to work herself to an orgasm by grinding against the bar. when she fails, the TENS is cranked up one notch. we get to 8 before she starts begging through her gag for her vibrator toy. she gets to orgasms from her vibrator, but her nipples are shocked at full power at each orgasms, leaving her screaming, drooling, sweating and completely spent. One of my all time favorite predicament scenes with an incredible pain slut and submissive.
