So for a little more detail, right after they were finally done (3 freaking hours), I actually went to the AirBnB. She called me and begged me to show up while he was still there. I walked in, they were in bed together, and she kissed me deeply, then told me firmly that I had some cleanup to do if I wanted to fuck her. So I did. Then he left, we fucked for like an hour, had great dinner and conversation, drove back to our house, went out on the town, and then went home and fucked again for another hour. Still all lovey to this day.
