You have an idea

You decide that it's time to take your fantasy a little further...

You hate the idea that Sarah would ever cheat on you... but for some reason you kind of love the idea of her being a bit slutty... her beautiful body, face.. and curves being used to pleasure another man.

You happen to be in contact with Tim, you actually used to be pretty good friends before you and Sarah started dating, but that all stopped when they broke up because she wasn't treating him well enough. You remember at one point she actually made him cry by teasing him about his skinny and pathetic body... For a shy and sweet girl she really does carry a touch of aggression. Not in a cruel way, but you can tell that she was pretty spoilt as a young girl...

You decide to call Tim, you knew this would be an easy sell. You still have him on Facebook and he hasn't had a girlfriend ever since him and Sarah broke up. You're not sure if that's because he's a bit pathetic or still has a thing for her but either way you know you can have some fun with this.

"Hey Tim, it's John, I know this is kind of weird and out of the blue... I mean, we haven't spoken in years but I have a proposition for you..." the conversation follows on for about 15 minutes more, you manage to convince Tim that you are "unable" to satisfy Sarah's needs anymore and that all she asks for is him.

You agreed that he would come over on Friday night and get head from your wife. Now you just need to convince Sarah.
