"Well? Are you going to answer me? Have you been sucking cock behind my back all along?" I asked her accusingly, "Or is it just Ron's giant cock that ...as you all shook up?" I pointed at the giant fuck stick in her hand, and noticed she was stroking it slowly, maintaining his erection. "Because you looked pretty experienced and comfortable deep-throating him!" She was pretty good," Ron offered. "Shut the fuck up, Ron," I barked. "no one was asking you." Dad, I -" I am talking to your mother!" I. He was rather familiar...Perhaps we had even met before. That must have been why my friend Kathad sent me a text saying “have fun!” He must have been asking about meand she had sent him here. Anyway, I thought, I’ll ask him when he comesout of the bathroom.I went back to my bedroom which was just across the hall, and couldn’tresist the urge to start touching myself again. I laid down on my bedand ripped my stockings off this time, pulling them hard, down towardsmy feet and off. I pulled off the. Then my mom pulled my hand and said to go bath and come still that breakfast will be ready and my mom was smiling see me. I went and masturbated thinking of my mom and took bath and came with towel nothing under it. But still mom was in kitchen and preparing coffee so I went again and hugged with more force this time from behind and my dick was rock hard which was pressing my mom ass. Then she did not say nothing this time also I thought I got green signal and my mom moved towards the dining. My step-grandmother was a very classy lady, quite pretty and trim, who had been a judge's wife until he died of a heart attack about three years before my mother married her son.My grandmother took to me and I took to her, we just clicked, if you know what I mean. So, I spent a lot of time at her house, often overnight, sometimes with cousins, sometimes by myself.Her house would probably be called a mansion, it was large, three stories with many bedrooms. I always enjoyed staying overnight.
