After a few minutes passes I pulled her down to me so I can kiss her and suck her tits. I kept her in that position as I fuck her from the bottom unti... I had enough of it. I then flip her onto her back and place my cock in front of her face and say clean it up. She started to lick and suck my cock for a few minutes before I told her that I am going to fuck her so hard now that after this she won’t be able to walk straight for a few days. With that she lay back with her legs spread and say to me. “How old is her brother “.“Same age as me – 12”.“How often have you fucked her”.“I have no idea – a lot. We both have”.“Does she mind” .“No- she enjoys it and often she asks us to do it to her”.“What about her brother don’t they know its wrong for brothers and sisters to fuck each other”.“Yep – but they don’t care. She cant get pregnant so she doesn’t care”.“Do you cum in her”.“Sure – she doesn’t mind”.“What happens if he fucks her first and cums inside her? What do you do?“I don’t care I just. Be at the window". This was unexpected but also a very familiar message. It meant she was coming home with someone and intended staying outside on a sofa we had placing in front of our lounge room window. The window had a reflective film on it that enabled me to stand up close without anyone on the other side being able to see in. There was a street light in front of our block and our high fence made the front yard very private. I couldn't work out what had happened to her "work rules" that she. I asked him if he was seeing anyone. Since the divorce he had lost the desire to date. I could tell that he was lonely. Late one evening I was awakened by the need to urinate. I tried to ignore it and hoped it would need---it didn't. I got up and staggered out into the hallway and down towards the bathroom. In my sleepy stupor I did not notice the light seeping out underneath the door. I turned the knob and pushed the door open. Sitting on the toilet with his pajama pants bundled down around.
