New woman i met invited me in, got me naked then asked me to leave...

I met a rather attractive lady during the Viet Nam War Era at a dance lounge. We had a lot of fun together and she said she had to leave for home and would I follow her home since we lived fairly close to each other. I followed her to her safety zone and told her good night and I really had a great time tonight. She invited me in and I told her I really couldn't stay long I needed to be at work at 7am. We went in, she made me and her a drink and we talked a few minutes then she started kissing me which I thought was alcohole related and she said " do you mind if I go upstairs and get more comfortable"? I agreed and upstairs she went. In a few minutes she hollard down and asked if I was dressed and I repected her, her replied yes and then she told me to get undressed and get comfortable so I did. In a couple minutes the lights went dim and she came walkinging slowly down the stairway in a very pretty feminen gown. She was fantasticm I was naked and laying on the sofa when she sat in the recliner next to me and moved colse to me to where I could even see her completely. She asked me not to watch her and so I turned my head looking down to her nicely pedicured toes and feet, which were very sexy and and got the results she was waiting on. As I was watching her feet I saw her toes start reacting to what I have known women to do when they climax. She stood upm handed my my closes and asked me to leave and please don't come back. Does anyone know what just happened? I still don't know and have never heard of this happening before. I need answers please, if you have a same type situation to base your answer on....Thank You!
