We had talked about sharing her and a mfm threesome for about two years and it finally happened about two months ago. My gf subtly mentioned my friend as a “joke” but I had a feeling she meant it lol. Anyways, my friend and I talked about mfm threesomes back when we were in high school, so I figured why not ask him? We talked about an eventual threesome between all of us but my gf wanted to hookup with him alone first to get a feeling. It didn’t bother me as my friend and I have been friends for years and he’s one of my closest friends so I trust him 100%. Well, one night we all hangout and when he was getting ready to leave, my ex walked him to the car. I figured she would maybe make out with him a bit and suck his dick but turned into full on fucking in his car. So I’m just going through all the old texts to relive the moment
