My wife and I were talking about sexual fantasy's one night about a month ago and she asked if I would ever consider sucking a cock if given the opportunity. I told here that I probably would in the right circumstances. This past week she brought home a gay friend of hers from work. She introduced us and had me go to the kitchen with her to help make drinks for us all. She told me he was gay and she wanted me to suck his cock as she watched. Her friend knew all about what was to happen before coming home with her. Two hours latter I was naked at my wife's request and so was her friend. Then my wife told me to let her friend suck my cock and in turn I would have to suck his. I did as told and actually swallowed his whole load. My wife was so aroused with watching us that I had sex with her for an hour after her friend left. Last night things changed big time. My wife told me that she had a chastity device for my huge cock. I figured this was all in good play, so I allowed her to install it on me. She had a hard time getting my big cock into it but finally managed it. Then she told me that from now on if I ever want my cock let out I have to suck a cock first.
