Done this twice now but don’t know if it’ll happen again due to me being in a new relationship. About a year ago I started seeing an ex gf of mine for sex following another break up in which I got cheated on.
Going back to my first ex for sex was a bit of a low point but we were able to do some fun experimenting as she got really into anal and pegging me. She started getting really turned on when I told her about some of the same sex experiences I had had, so we decided to try a threesome.
We did this twice properly and both times were great. It was pretty simple to find a bi guy online who could host us. He was a skinny black guy a few years older than us with a thick 8-9in dick that we both went to town on. Both times started with the two of us blowing him and making out with his cock between our lips before he and I started to fuck her, taking turns on her pussy and mouth. The second time my ex had been doing more anal and we were able to double penetrate her for her very first time. Overall great experiences that I’m glad I got to try.
