My Sister Forced Herself on Me

My sister and I had a wonderful sexual relationship over thirty years ago. Sometimes we slept in different rooms in different beds and sometimes we slept in my bed. My folks never said anything and were clueless to what went on during the night. When we slept in the same bed we usually fooled around late at night. She slept in the other direction and when she was needing it she would tease me with her feet usually putting her foot towards my mouth and that was the signal I needed to start sucking her toes and then proceeded to undress her as our play got more heated. When I wanted it from her I would tap her foot with my hand or would remove her socks if she wore them. She would then give her feet to me and we’d proceed to more pleasure. If we slept facing each other then either one of us would tap the soles of the other with our foot to indicate we wanted to play. There were times when my sister was in need more than I was and she would come into my room if she wasn’t already in my bed. She would remove my socks and touch my feet or she would move my underwear aside or pull them off and then grab my flaccid Peter and proceeded to rub it and then squeeze it very hard to when it turned purple. I taught her the squeeze technique to use on my cock to keep it hard and from preejaculating but my sister used the technique to have her way with me. She’d get it hard and then squeezed it so hard it hurt and she’d twist and pull on my poor weenie. She would use full force with her leg and feet to get her foot in my mouth that she basically kicked my face that tears formed on my face. She would lock my legs hard around my head when I ate her and she wanted more than I wanted to give her. She wanted me to penetrate her vagina and would forcefully guide my cock to her opening or position herself cowgirl style and force her vagina onto my dick. I did not want to enter her vagina, I mean I did but I did not want to make her pregnant and then all hell would be loose so I never put my weenie inside my sister but I did give her anal sex and I would quickly maneuver my harden swollen cock inside her butthole as she sat cowgirl on me.
