The next evening Karen called Clayton as requested. I was not permitted to hear their conversation but Karen was quite excited after the call and I was just told to “Wait and see” On the Saturday, Clayton arrived and I prepared drinks for both him and my wife while while they sat on the couch kissing and caressing. When I came back from the kitchen Clayton was naked and had my wife’s blouse and bra off and was sucking on her nipples while he fingered her wet pussy under her skirt. She was letting him know how much she was enjoying it through her groans of sheer pleasure. When they saw I was back in the room they stopped what they were doing and Karen started speaking. Clayton was still playing with her nipples while she had her hand around his very hard cock. What she told me was what they’d discussed in their phone call. She said “I now belong to Clayton, my pussy is his and his alone. You are not allowed sex with me from now on. Clayton knows you can’t satisfy me so you’re not even allowed to try” While she was telling me this Clayton was smiling at me. It was a smile that clearly stated he was in charge. He took over from Karen and said “From now on, when I am here, your job is to serve us. You’ll get our drinks and anything else we want. I’ll call you before I visit and let you know what I’d like her to be wearing and you will help get her ready for me. She is now my slut and you are the cuckold” Obviously I wasn’t being forced into this against my will. I really enjoyed Karen fucking other men and she knew through our talks after she had been with Clayton that I really got turned on hearing about what they’d been up to, and she enjoyed the jealousy and humiliation that came with my excitement. What came next though, wasn’t anything I was prepared for. Clayton continued “The next time I visit I don’t want you dressed like a man. A man satisfies his wife and you can’t. I think you’re a sissy so next time you’ll dress like one”. I’d always had a bit of a fetish for sexy underwear, stockings etc, and Karen had told Clayton about this during their phone call. So they’d decided that, for future visits, I was to be dressed in sexy undies. It turned out to be more than that.
