We carried them inside and into the kitchen, I asked where should I start putting stuff and she said down there pointing to a cupboard at her feet. I ...nelt down and she handed me a couple of tins and I put my hand up to get the next item without looking. I got a surprise when instead of handing me something she straddled my hand and I got an even nicer surprise finding out she was wearing no panties. She looked down at me and said "I bet you're a real filthy bastard aren't you" I grinned and. My last adventure with her I took sole care of her, as her Dom that is my responsibility to make sure she is cared for. Today she decided that my caring was a weakness. She didn't say that but I could feel it, until she fessed up. So how do you get the truth from someone. As we sat there chatting I worked in close to her, not so close as to crowd but close enough to share some warmth as the snow fell around the truck. I looked into her eyes, said nothing just letting her talk. When I finally. “All yours” said Klaus. And he didn’t need to say any more.Sammie was all stirred up for a butt fuck. She needed a cock up her arse. She got one all right.“Oh fuck...Oh shit...Dad” was all she got out as Hamish butt fucked his own daughter.Man oh Man; talk about new sexual heights. It was the combination of the absolute taboo and the sheer stunning tightness of her rigid arse funnel that had the dad transfixed in a pleasure spasm of no return. He would cream his own sweet Sammie’s arse so. Then they returned the favor taking turns sucking my cock until I finally came in Lisa's mouth. We didn't have time to fuck. We all had to take quick showers and air out Julie's room before Mom got home. When she did return we were all sitting at the kitchen table with our books doing homework and enjoying a snack. For the rest of the week, we played pretty much the same. I could not find a safe way for me to have some time alone with either one of them. I got the feeling that they had become.
