Over a couple of nights I listened to their soul searching, until they finally agreed they wanted it. Mum was going to have my baby. I continued to fu...k her. Every two or three weeks I'd do her. No warning. At home...or I'd call and tell her to meet me at one of the houses she was showing...or at Graham's cabin. I loved the afternoon I spend sexing her on Graham's bed.I was always masked. And strangely, after a while she stopped asking who I was. I think in some way it made the sex even better. They were obviously hot for it because no sooner had thecar stopped than they were groping and feeling oneanother. This was making me really randy and my cock wasuncontrollably bulging against the thin material of myshorts.After about five minutes they got out of the car andcame and stood right by my window, the boy feeling thegirl’s tits and then slipping his hand up under hermini-skirt and under her knicker elastic. He was wearingthis really tight pair of bleached Levi’s –. He told her to watch the screen not to take her eyes from it. He placed the end of the shaft on her clit turning up the force of the water feeling her squirming away from him, he began moving it forward and back, holding herlegs together enjoying the control he had over her. He pushed the shaft back and up up into her cunt, openeing her legs fucking her slowly in and out harder and harder faster and faster, She was cumming he could feel it building insider, he looked at her face she was. It had a lot of sex in it, alot of the sex was between family members and I made comment that it would be nice to have sex. Mom giggled and said that it would be nice if we could help each other out, what would it hurt. We giggled but as we sat there I got to thinking more about that. What would it really hurt if mom and I had sex? We were not going to have babies and it would be better than having sex with strangers. My cock got hard at the thought of me plunging it deeply into mom's cunt, her.
