I have fantasised about my wife taking another man's cock for many many years I have asked her if she would try it loads of times she always says no. My friend James calls me on the Monday and invites us to a barbecue on Saturday I accept that invite and I tell Tracey that were going during the week I relies that James brother mark will be there on Saturday so I start my planning. Saturday arives and me and tracy are getting ready Tracey puts on her white flimsy summer dress white sexy nickers I tell her to leave the bra off she put on her sandals and she was stunning we got in the taxi I couldn't keep my hands of her in the back seat of the taxi we arrived at James and the barbecue was already in full swing we mingled for a little then I caught sight of mark through the crowd he came over and started talking to us we hadn't seen him in a few years he kept on staring at tracey after a few hours Tracey had a bit too much to drink the barbecue started winding down and I said to Tracey the taxi will be 5mins I said to her that I have invited mark back with us for a drink as I have not seen him in years she said OK we got back to our house and I started pouring the drinks out Tracey put on some music and she started dancing when she twirled her dress went right up and you could see the nickers Tracey was wearing I told mark to dance with her after a short while they were groping each other and I relized what I was imagining all those years was about to happen.
