From pain to pleasure, estimming can be a wonderful thing

Dressed in green lingerie, my dick and balls are bound tightly and wired with a tens box. My nipples are clamped and connected to another power unit.. My nipples are gonna get zapped a lot this session, which always causes my dick to leak precum. I begin edging myself with the tens units. My dick is flaccid, but if you look closely, you'll see it start to throb a little. The tens pads send current bouncing back and forth between my balls. The other pads connect my dick with the spot directly over my prostate. I grab my bound balls and crush and pull them hard. My whole body spasms as I try to keep just this side of cumming. Finally I can't take anymore. My muscles seize up as I reach a climax, and I enjoy a wonderfully painful hands free orgasm. Used correctly, the pain and pleasure you get from estimming can be a wonderful thing.
