We love both. My gf coming home after being with another man and still full of his cum or me watching him with her. They are different but both very intense and erotic. I just love that moment as he first enters her. And then when he cums.
Our sharing always took place while both of us were present .99 times out of 100 anyway as I did give them some privacy on one occasion . I must add that this information is " as far as I know " lol
Since I traveled for my job, we agreed it was ok to see others, but was to tell each other, but I know that I had a few secrets and I'm sure she did too. She really objected to me seeing young college age girls. (all legal age)
