Haha, nice, devious idea. if he was a local sub, I might have done something like that, then locked him up for at least a week as an alternative to continuing the post orgasm torture. But since he was soon going to be getting on a plane back to Germany, that wouldn't have been a very realistic option. I mean I could have locked him in a Holy Trainer which isn't detected at airport metal detectors. But long-term chastity isn't something that we had discussed him being ok with, and not really sure he would be. He's more of an in the moment play session kind of sub vs. long term control like that. Although you do make a good point, since post orgasm torture can be VERY persuasive... *evil grin!* How long would you have locked him in chastity for as an alternative punishment for cumming without permission?
