My wife had a spiral hormone probe installed in her cervix wich made her hormones go nuts, one time she was super horny the other she wasnt at all. Also when she was horny and we tried sex in those first weeks it just hurt too much. This led to a talk where i explained that i am getting really sexually frustrated and need an outlet... She agreed and asked if i wanted to "as a couple" bring a prostitute home. the idea was i fuck her in front of her and then i get her off with my hands so both get something out of it.
This was all while i just started a new job and had to go to work by bus, on the bus i met my current gf, a cute 18 year old at the time. after a week or so she became very open to me, admitting she liked me and i opened up to her about the situation in a vagueish manner to respect some of my wife's anonymity
I talked to my wife about not taking a prostitute but have this girl over, told her i really like her even if shes still young and that it would save money we needed since i only just came out of a time of being unemployed. She begrudgingly agreed but wanted to meet the girl first and then decide.
I invited her over to have dinner with my wife and chat, she was aware my wife wanted to get to know her to decide if we would do a threesome but i told the little mynx to keep it on the down low and pretend its just a friendly dinner.
we talk and have fun, i made sure there was enough wine and liquir to get a social connection and possible awkwardness out of the way and while none of us were really drunk, we got tipsy quite fast.
I made the mistake of asking my wife what she thought about he (lets call her Mynx, since its my play name for her when we fuck)
My wife said she liked her too, and she still had to think about it, but she was opening up to the idea. Mynx thanked her, walked over to me and kissed me on the lips.
It was such a bold thing to do that i was a bit in a panic, and just kissed back out of reflex.
