TENS Unit and Leather Bondage
From here:
Then, as I milled about watching various attractions such as these, the homeowner announced a special treat for everyone to watch: the owner’s submissive wife had a friend who needed some exquisite torture. The homeowner obliged. He brought a large leather V-shaped sarcophogus to the base of the staircase of the dungeon, and she slid her naked self into it, her arms tight at her sides, she was unable to move inside this leather case. Then he hooked this V-shaped torture device to another electronic device that suspended her in the air…she was about 5 or 6 feet off the ground, tightly bound in leather, covered from head to toe, with a blindfold on.
The leather sarcophogus had 3 zippers on the front…one for each nipple, and one for the pussy area. I watched, mezmerized, as the homeowner unzipped each area, and then zapped her with a tens unit. It was like watching the prize catch of a fishing trip, being photographed on the dock. She flailed and writhed as the sarcophogus moved back and forth and side to side uncontrollably as she felt these electric shocks going to her moist nether regions. She also had a ball gag in her mouth, so she couldn’t say a thing. It was magnificent to watch…and she was a limp ragdoll afterwards, smiling from ear to ear as they carried her upstairs to ravage her in the orgy that was still going on. That chick was the luckiest submissive in the whole place.
