When we were growing up my parents rented this river cottage for a week every summer. The water was cold, my mother called in wiener shrinking cold. We got out of the water and sure enough my wiener was gone. My mother had this habit when we got back inside of warming up my wiener with a towel. She stood over me and rubbed my wiener, before letting me go to get dressed.
My mother touched my wiener growing up, when I was older she would pat my wiener in my pants, 'get your dick in the chair'. I had a sister a year older and she had this face she used when my mother talked about my dick. My mother told her she didn't have a dick so she wouldn't know.
One afternoon, it was the summer after I turned sixteen, my sister came in and asked me if I would touch her, feel her up. She needed to know and the other girls at school had all been felt up and she didn't want to go back to school after the summer. She opened her legs and took off her top and I touched and felt her up. She wanted me to continue feeling up her girl parts, not to stop and she had an orgasm, squeezing her legs shut and holding my hand in place. She told me I could kiss her, which I did. We ended up doing the dirty deed. We lost our virginities that afternoon at the river cabin.
That was once, it didn't happen again. But she and I were never again the same, we were closer than close, and she would tap my wiener and asked me how my dick was doing. She told me when she got it on with a senior boy, and she was there when I got it on with a sophomore girl. She stood over us, "honey you have to 'open' your legs", and she opened her legs by the knees.
