She asked for us to invite him over so he wouldn’t know she was cheating.Margo agreed because she liked his small cock in her ass. I liked him to fu...k her because he cums twice to my once ,and sloppy seconds pussy feels good.When we got home she saw him working in his garage and asked him to come over later. He told her that he had his friend Chuck coming over,and asked if he could join us too.It was sure luck and not knowing anything about him she said yes. We later found out he was ,just. “Like a bet? Sure, what are we betting?” she asked.“I don’t know, got anything in mind? Money, dares, clothes,” I said with a wink.“Clothes, like strip racing?” she said.“Sure why not, its just a friendly game,” I said. I’m pretty good at Mario Kart so I was hoping I could win a few races and get her naked.“Fine, I don’t have a problem with that,” she said, catching me off guard.“Alright time to go.”The first race went fairly well, I ended up winning just barely and she took off her pants first. An hour later Sarah sits me in a chair with arms in front of a full length wall mirror. We are surrounded by mirrors on five sides.“You can watch me pleasure you with my tongue. Or you can suck my man’s nine-inch erection while you watch in the mirror? Perhaps both at the same time, Linda?,” she smirks knowing I want both.“I need both Sarah, you have really turned me on.”“Best of all I want you to watch him fucking me.”Sarah organizes me in the chair and places one of my legs over an arm.I am. It was never said, but I believe that he fucked PF also.This went on for a while and at one point we had discussed the possibility of meeting another couple for her to have a F-F sexual experience and a 3-some / 4-some with another couple. I got online and found a guy who seemed nice and we invited him over for dinner. PF dressed sexy and after dinner and some wine she ended up sucking Richard and then rode him to an intense orgasm.Richard had a nice cock and PF really liked it and he came over.
