My passed out mother.
My family would often lay around naked in summertime in our house.
One time, with my father and sister on one couch, and myself with my mother on the other. Dad was always spooning my sister (yes, he banged her right in front of myself and my mother. My mother seemed fine with it) and you know how spooning leads to forking? Well usually, I couldn't see much because the angles of view were never quite right. I knew when it was happening, as my sister would be breathing like she was freezing (although it was actually hot), and dad would be breathing heavily. There's also the obvious humping movements that gave it away.
This particular time, my sister had her top leg lifted and I couldn't see my father's face, it was behind her head. Plus, she was facing towards the television so she couldn't see me watching. I had a clear view this time, and he was slowly pushing deeply in, then out of her.
Before I even realised, I was totally rigid, placed perfectly against my passed out mother's bits. I slowly and quietly moved back and forth, being careful to not disturb her or let them see. It didn't take long and I had flooded my mother's naked crotch with hot seed. She hadn't woken up, and I was too frightened to move. I ended up falling asleep myself.
She must have known. I woke up alone in the living room naked. Everyone was in their bedrooms.
She never said anything about it later. I was worried everyone knew at first. Now I believe she didn't even say anything to my father.
Your mom had nothing to say about your cum as she did enjoy it too. Next time just enter her pussy in spooning position as your dad did to your sis! She will love your young cock!!
Please tell us more about your dad fucking your sister?
I need to take my mind back there because now it's a turn off, but then it made me hard. Mostly because he acted like there was nothing going on, but also because my sister was so easily excited sexualy. She couldn't stop her hips grinding, and her sexy little moans and noises were horny as! Plus, you could often hear how wet she was. Nobody knew that I had been fooling around with my sister for ages, so I knew how hot she was in that way. The fact that it happened usually in daylight, and always in full view of myself and my mother, plus he wouldn't use protection and grunted as he came in her. As a teenager I found it erotic. It turned me on knowing that my sister had a secret that only we knew for ages. The fact that I was also guilty of fucking a family member. The same one! I knew how wet she would get as you started going a little. I also knew that my 8 inch cock was smaller than my father's cock, he could fuck her deeper, but I could fuck her harder. She settled down when she left home and moved in with her boyfriend. He4 step brother! They had a kid and she left him eventually. She is married to another guy now and has two more children to him. She also lost heaps of her hot looks after she started having children. My father died years ago and we were all happy about it.
