There was a story I found a long time ago about a guy who was into self bondage. He ordered a sleep sack online that has a computer or timer to release him. The sack also had built in electrodes for his his dick and balls and an anal plug (maybe other torture items, I don't recall). It was supposed to lock him in for a few hours and torture him while edging him and making him cum. But when he first tried it, it errored out and the guy was trapped for a long time.
Any ieas?
