Alt toon obviously. I was interested in my wife's friend for quite a while. When she started dating my buddy I became more interested. After some life changed (moving around and her becoming single) she hit me up. It was innocent at first. She was just venting to me and I helped her move out of her ex bf house. We started talking a little more intimately. She asked about how my sex life was and if I talk to other girls. I took it as an indication of an opening and told her. We talked about life plans, past decisions, spirituality etc. And there was a legitimate connection but it wasn't....romantic love. She is an awesome person and I feel like she is easy to talk to as a friend (that I'd like to have sex with) but that's it. Not wanting to lead her on I told her that. She agreed! It was an amazing text to recieve. We continued to talk and one night she calls me and wants me to come over. It isn't a bad marriage, or a fight we had, or a strained friendship between them. We both want each other sexualy and in our friendship. I went over. She vents to me about living with a friend while she saves up for apartment. We laugh about almost everything; life, TV shows, how things used to be. And continue laughing as things get physical. We joke about her roommates coming in. We decide to move to the garage on a pile of freshly washed laundry. No joke. And we get to it. But it's so different than anything if been a part of before. It's passionate but it isn't like putting on a show. (I was reminded about reddits advice that sex isn't a performance and is supposed to be fun. And it was exactly that. Fun. Sadly we were broken up by her roommate actually coming home which we laughed at even more. And we decided to try again another time.

Tl;dr: I fucked my wife's friend and it was pretty great.
