Mom joined us to watch TV. She had on a blouse and a knee-high skirt. Her tits pushed out the top of her blouse and her ass filled out the back of her...skirt. I had her sit down in my lap. One buttock was right on my crotch. She watched silently as my cock hardened and pushed up against her butt. My cock started hurting. I moved mom gently aside so that my cock lay between her cheeks pressing against her soft crotch. Mom watched like a statue. Dad has all his attention on the book in his hands.. We started growing porn sites and reading sex stories but never had sex, I mean copulation. I asked her to show her samosa. She asked me to lie down and she stood above me and I could see her panty inside the skirt and she slowly removed her panty a side and closed it off. I was not satisfied. She said that’s all. I was angry and shouted back her saying she saw my dick and licked and sucked it why not me. She kissed me and said not everything in one day, we are left with ample time in our lives. I turned on the TV and leant against the worktop watching some crap. I heard the foot steps coming down the stairs and my daughter came around the corner. Fucking Hell dad she said. Your pissed as a fart. Then from behind her two friends appeared. They were all laughing at me. Well I was pissed and prob looked like an idiot. My daughter who was18 came over and grabbed me and pulled me through into the lounge and sat me on the sofa. We are back up stairs now so see you later she said and off. I paused for a moment and rubbed her cheeks and asked Are you doing ok? Y…yes…sir, she sobbed. I just couldnt resist this gorgeous bottom so I said, Just a few more, I think, and then we will send some pictures to your father. and I started again before she could reply. Another 20 or so to each cheek and I stopped and stroked her again. When you are ready, please stand up in front of me bent over with your hands on the coffee table and I will take a couple of pictures. I continued gently.
