My wife has cuckold me for our entire relationship. I say relationship and not marriage because she had sex with other guys before and after we wed. After learning about chastity she has bought several devices to lock me in. The first was a CB 2000 bought in 2000. The cage is large and very uncomfortable. I would wear it but she could tell it hurt so she bought a CB 3000 the smaller tube was easier to hide but it pinched while I slept. Her newest find was an extra short stainless steel cage that has a screw in tube that is inserted in to my penis. The first time she put it on me I could tell it was much more comfortable than the others. Then when she showed the tube to me I got a little sacred. She was able to insert it with no problem , the feeling of it sliding up my penis was very erotic. She screwed the ball end of the tube in the threaded end of the cage. She used a rubber glove to keep her fingers from slipping as she tightened it tight. I in a normal day I often forget I'm wearing it. And sleeping is also easy. If I lay face down the device is so small and short that it rest between my thighs. The extra weight of it being stainless steel is also kind of sexy. While naked it keeps me reminded of it being there.
I've tried the CB6Ks and my testicles have escaped almost every ring size but the smallest with no gap between them (flush). And many steel devises too. (Balls are too flexible) But we keep trying.
Both the CB devices hurt my balls. And I could get out of the 2000. I was thinking that they where all that way. My wife said a co worker bought a stainless cage for her husband but it was too small. She told her friend about my extremely small penis and asked if she could try it on me. She brought it home and I love it. In fact next month we are going to Florida for a week and my wife plans on leaving the key at home. Last year while vacationing she got lucky one night on the beach and I had to stay in the room jerking off. Being denied this year will be exciting.
