Cleaning Up After

My wife and I love mutual masturbation and one rather erotic night, we were in front of the fire and I was straddled over her stroking myself over her breasts. I asked her if she was enjoying the view and she replied, yes but I would enjoy it more if you would clean up afterwards. Not knowing what she meant, I asked and with a dirty little smile, she told me she wanted to watch me lick it up afterwards. This caught me totally off guard as I had never heard her say or do something like this. Of course, I came in 1.2 seconds and gave her a show to remember.
