Nazryana is a tough girl compared to my other slaves, so I wanted to give her some disadvantages for this endurance test. First I pierced safety pins through her outer labias, then attached them to rubber rings on her thighs to expose her inner labias. Then I made her to stand above a metal beam full of candles, legs wide open, standing on two chain loops attached to the ceiling. In this setup her own weight makes her legs spreading apart and eventually she falls on the candles with her stretched out pussy. To make it even harder for her, Diamond and I started to practice shooting rubber rings to her stretched labias...
