My Wild Cougar Poly Advice

I met my wife a few weeks before I turned 19. I’ve always liked older women and I have been very open and blunt in talking with them. Well, one of the few times it worked out happened to be the woman I married. She’s almost 11 years older than me and our married has been amazing, both in and out of the bedroom. She has vastly broadened my sex life and I’m truly grateful of her. In the last year we’ve been playing more with MFM and FMF. Both have been wonderful! The past two months she has been enjoying seeing me fuck one of her Trans friends. She completely passes as a woman from head to toe minus still have a pretty decent cock, I thought she was a full blown woman the first time we met. Well up until this weekend I had been enjoying fucking her in the ass and enjoying the sounds of her hard slapping cock and balls. We decided to change things up a bit, and she fucked me for the first time. It was strange and a bit painful at first but it turned into just hot wild lustful passionate fun for all three of us. My wife was the most worked up I’ve ever seen. She loved everything about the situation and was a perfect hot slut for my cum. Our special friend is about 6 to 7 and half inches long but has surprisingly large girth. I didn’t think I was going to be able to take it being my first time, and I almost called it quits with the pain but my wife helped me through and I’m sure glad we did. There was something exceptionally different about getting off with a fat dick in my ass versus just cock stimulation. It was profoundly intense, and felt like it lasted longer and the rush of chemically induced euphoria that came from the anal stimulated organism was a whole new wave that I hadn’t experienced until that point.

Through the night we all switched up an earth shattering evening. Normally my wife and I keep or extra play to the weekends but our special friend has been over almost everyday since. My wife and I are talking about having our special friend move in with us and me a third in our relationship.

Has anyone ever been in a three person relationship, or a poly fidelity relationship? I would appreciate hearing some other experiences and or advice. Thanks!
