You know, EvilMJ, we have recently explored playing solo. For me it is fulfilling Mrs. WS's fantasies of playing alone. I know it can be fun not having to worry if I'm having fun, etc. So I have set-up little "missions" we call them to play with others. And it's hot for me giving her this, and then she calls me the moment she gets in the car and tells me all about it, she comes home to me and we go at it like Mallard ducks in heat.
On my end of it, it has so far had nothing to do with incompatibility between me and the wife of the couple because, well, it seems that in these situations we both think the wife is hot, but the husband is not attractive to Mrs. WS. When she plays alone it is because of the above paragraph.
The idea of me playing alone turns Mrs. WS on. I haven't done it yet, but it will happen when the time is right. It's allot easier to find a guy for Mrs. WS to play solo with then a single girl for me. Mrs. WS has talked to the wife of a couple that I am really attracted to but Mrs. WS is not attracted to her husband. We have been honest with them about this, and he is okay with her playing with me solo (they also play solo on occasion). So we'll see.
Mr. WS
