I was in one for a while several years ago. It did do the job. He had total control of my clit. He did not want me fucking his pussy so he kept the key. He wanted her deprived and ready for him. She used her realistic vibrator a lot more. It got to be a hassle for him seeing us as much so I promised not to fuck her and was let out. i had to let her fuck someone if she needed to. We still done some local threesomes i just didn't fuck her. At least I could jack off. I could do anything with another man. I was at work one day and she called and said one guy we were seeing could meet us about 50 miles away which was about half way for both. I couldn't get loose so I told her to go see him by herself. That was the start of my cuckoldng. She came back a complete mess. I could tell he had fucked her a lot. I was really turned on by that. I ate all his cum out of my wife. We decided we both liked it and would do more of it. She told me or called and told me she was going, where to, and about some time schedule. We didn't consider it cheating but more of a needed arrangement good for both of us. Usually it was a half day deal but some turned into overnight. We understood there was a fair chance of her being seen with someone. Everyone knew us. We just thought that made it even better. I haven't fucked her now in over 15 years. A very few people know about us. And they are fucking her.
