We were talking about it last week and she finally admitted to having a fantasy of being taken by a man with a much larger cock. The next day I phoned her at work to tell her I'd gotten her a very special Christmas present. I made her wait until she got home to tell her what it was going to be. Getting us both undressed and puting on a porn film I told my wife I'd arranged for a guy I work with, a guy who I know to have an eight inch cock, to visit us at home on Christmas eve and have sex with her.
If my wife had been keen before she showed me how much more keen she was by having sex with me alone. Tot using any sex toys and for the very first time since we've been together, she came by me and my cock fucking her. It was the best sexual experience I could ever give my wife and I loved the fact she came all over my dick. She's told me daily since, how much she loves me and how much of a real true man I am, buy allowing her to fulfill a fantasy she'd always had.
The thing is I'm now regretting my decission and I'm worried she'll always want to be with a man who's more well endowed than myself in future. If I don't go through with the arranged sex night, then I don't know what her reaction will be and if she'll just go out and find someone else anyway. I'm now wishing I didn't bring all of this up in the first place, but I do love the fact my wife and I are having the wonderful sex we are and I'm now making her cum with my cock fucking her, after all this time together.
