I was 12 and when the rest of the household were out i would watch my foster mom in the bathroom wash.She was 49,small with a nice full body.While watching i would pleasure myself even though i only saw her from the back mostly.I used to admire her bare shapely bottom.It wasnt until i was 15 while watching her wash wearing only a shirt, i approached her and asked if i could wash with her.She half turned and saw my hidden arousal and said of course son.Her shirt only came to the top of her bottom so i was really aroused.As i slipped off my jeans slowly not knowing what if anything would happen she suggested that we could wash each other.As i slipped off my pants she started to soap me all around my p**** telling me how important hygiene was and that i was a lovely boy.She then showed me how to wash her as she removed her shirt.Now both n*** we began washing each other with her complimenting me on my body.Being as tall as her i immediately threw my arms around her and told her i loved her while my hands were all over her.We kissed and then went to bed which was mind blowing as i was still a virgin. Yes learning all about s** from a woman in her early 50s was awesome. You always remember the first time when a woman guides you inside her and you pleasure each other.We slept together for years after this whenever we could.
