She took his hand to lead him down the hall to our guest bed. I get harder when I hear her moan as he takes her clothes off along kisses all over her body. My balls want to empty as I her them start to fuck. Slowly at first then faster and faster. She starts to moan loudly as he speeds up. I hear him pounding and pounding her married pussy. My dick is leaking in my pants as I hear her cum for him as she moans loudly. I hear him continue to fuck her as he goes twice before needing a break. This time it will take longer for him to cum but she will cum faster. My hard dick feel the need for her wet used pussy. I want to hear him cum inside her.
"And by the way. Before asking me out, he told me something funny. He said he really liked dating married women, because that way he would know that his date would have sex with him even on the first date. So I guess that by saying yes to him, I'm pretty much committed to spending the night with him. I mean -- I wouldn't want him to think I was a prude or anything like that. You understand, don't you?"
As shocked as you are by what your wife is telling you, it's obvious that she's made up her mind and that she WILL be going out on a date with him and WILL be having sex with him, so all you say at that point is that, yes, you do understand.
Your wife's best friend never liked you much, and has never hidden the fact that she thinks your wife is too good for you -- and that she would have much preferred it if your wife had dated her brother-in-law. So what really scares you about this message is that you know your wife's best friend would love it if your wife eventually left you to be with him.
