So over the years we've invited a friend of mine to sleep with my wife. This happened twice before we married and like 5 times since. But after he got into a serious relationship my wife said she wouldn't anymore as she didn't feel right. Well, that relationship is over so him and I are setting up a plan for him to seduce her. Here's part of my plan to him. I am changing her name in the plan.

So I think it'll have to be in phases. You haven't even seen Mary in almost a year. 

So phase one

You stop by sometime with both of us here. Maybe watch a Phillies game and order some pizza . When you get here, give her a hug, ask if you can have a kiss. Kiss her a little deeper and longer than just a friend kiss. Just a little extra.  Hug her tight, pull away and look into her eyes. No need to say anything else.  If you are on the couch sit next to her. Lightly scratch her arm/leg/back. She really likes being lightly scratched. When you leave, kiss her again. At some point I'll give you a few of my Mr happy pills for next visit if it gets to that.

Phase two

Some night that I'm going to class I'll call her saying you were just driving around and asked if you could stop by. When you get there kiss her long again.  Probably good to pick not only an aikido class night but also a Phillies game so you have a good excuse to hang on the couch together. If she's not done work yet ask if you can just hang with her while she finishes (her office is that second bedroom).  

[So if you do hang out with her while she's working, maybe when she's done ask her "could we have a little cuddle?"

If not then just watch the game next to her on the couch lightly scratching as I said. ]

Phase three

This one is up to you. 

Maybe ask for another kiss and just keep kissing.  

Maybe mention you were in a sexless relationship (don't mention hand stuff or anything) and that Mary was actually the last person you had sex with. (have you had sex with Mary in this house? I don't recall)

If anything happens, even if it's nothing serious like just hanging on the couch, make sure you text after sometime (very important) to thank her and suggest you do it again soon.  So a few things. If she asks if I planned this just say no but he said he'd be fine with it.
Also if you do start fucking her, she's not on the pill. Ask her if she has any protection. She uses VCF spermicide gels but it takes 15 minutes to reach effectiveness Please don't cum in her if she if it's not ready
