Well I have had the pleasure of fucking my older sister. It was about 5 years ago. There is a local dogging site on the sea front and one evening I went down there to see what it was all about. I knew my sister went there as I read her diary a couple of weeks earlier. I saw her boyfriends car and went over looked through the window which was steamed up and sawmy sister ducking off her boy friend she was naked with her arse in the air. I pulled out my cock and started wanking. My head was above the window so they couldnt see it was me. Suddenly the window round down and my sister stuck her arse out of the window. I stepped back in shock looking at her gorgeous arse and gaping wet cunt. I didn't have to think for long I took the head of my cock and slipped it into her fuck it felt great fucking my sister and she didn't even know it was her brother I was so aroused I had to pull it out or inwould had loaded her with my spunk as I did she turned around and finished me off in her mouth swallowing every drop. To my horror she looked up and said now fuck off bro or I'll call mum. Since then we haven't fucked but she sneaked me a peak of her pussy and tits every now and again.
