My wife's mother came for a brief visit and this gave me an opportunity to have some fun with her. I got up early one morning to make coffee. I was wearing my very short black nylon nightshirt that just barely covers my man zone. She came downstairs and was checking me out when I raised my arms over my head to retrieve something from the overhead cabinet. When I did this, the hem of the night shirt rose up, exposing me. I kept my arms raised for a while as she got a real good view. I looked at her and she was smiling. We had some good fun and it was a pleasant time for both of us. I tried to cover-up afterwards, but to no avail. I was way too excited for that. Oh well, such is life.
