New adventure imminent

We are going to have another meeting with one of the guys we have met before. My wife is to meet with him for lunch next week and then they will plan the scenario. It may or may not involve me but I will certainly be there afterwards when she can tell me all about it and I can taste and smell the sex. I am starting to get the knotted feel in my stomach which is a mixture of lust and jealousy together with heightened sexual tension.
In her texts to him she has intimated how she wants him tied up on the bed and she will straddle him until he cums in her pussy. He in turn wants her blindfolded and tied on the bed while he and I take turns to fuck her and see if she can guess who is who.
I love this thought even though I have not met this guy.

Will post more later
