Knowing how much slave john enjoys having his nipples tortured, I recently bought a device for My dungeon with him in mind.
How high could I stretch him?
We got further than this photo, actually. I am pleased to say that he was able to take as much as physics would allow. That is, the opposing forces pulling against his nipples eventually became too great for the tension of the clamp and one of his nipples slipped out.
Given his gasps, moans, and that far-away look in his eyes, I think he liked My new toy.
