When I was in high school I started to have an real interest in girls. I had been m*********** daily since I was 13 but now I began having fantasies about having s** with girls. My mother must have noticed this because she one time she came up to me and asked me what is that white stuff on my pants around my fly. I knew it was s**** from m*********** but I was to embarrassed to acknowledge that it was s****. I said it was chalk from school blackboards. My mother knew better and said that we have to have a talk about s** sometime. Several days later when my dad was at work and I was back from school, she asked me to come into her bedroom. She spent the next hour educating me about s**. She was surprised how little I knew about it. Since no one else was home (and she locked the bedroom door), she described the common s***** positions (d**********, missionary, on our sides and so forth). We were both fully dressed when we allowed me to simulate s** in these various positions. Towards the end of the hour, she asked me if I would like to know what it feels like to be inside a woman. She said that she knew it would be embarrassing for me but I should know. I wasn’t quite sure what she meant but I said “sure”. She slowly pulled her slacks down and removed them. She then pulled her p****** down and removed them. She asked me to do the same with my blue jeans and underpants. Then with both of us bottomless and my p**** already erect, she motioned me to come close as she spread her legs apart. She took hold of my p****, masturbated it fast and hard and then slowly inserted it into her v*****. She said it went in so easily because she was already “wet”. I didn’t quite know what that meant at the time, although I know now. The sensation of penetrating my mother was almost more than I could bear but she cautioned me against ejaculating into her. She said that she was still “fertile” and it could make her pregnant. We stood in a tight s***** embrace like this for what seemed like several minutes. Finally, she said “lesson over” and we pulled apart and got dressed again. I feel that I owe my mother a lot for teaching me a bit about s** and for letting me have a taste of it with her.
