I waited a few seconds and followed her upstairs and entered my room.Lay on the bed and thought, all I had to do was get both my sisters pregnant and ...we'd have the deed free and clear to our townhouse. They'd said there would be a cash bonus for each baby we had and it would increase with each child. The Foundation must be loaded to waste money on this. Giving money to boys to impregnate their sisters, crazy Foundation, but a stroke of luck for me.I heard a knock at the door and called. "Stop that," she screamed."Look my slut of a sister," I whispered close to her ear, "all I want is some of what you give Danny boy." Please no, let me go," she struggled but I was much too strong."You haven't even put your bra back on," I laughed, my free hand moving from one breast to the other."No don't," she wailed."Nice tits too," I whispered. "Now we got a few minutes before mum comes in, so what am I going to tell her? Be nice to me and I'll keep my mouth shut. Now there's a thought why. I sucked her nipples into my mouth one at a time and enjoyed feasting on them. I finger fucked her and I rubbed her clit to several orgasms. I couldn’t count them or keep track of them. She had several series of multiple orgasms. When I knew that she had enough I slipped my cock into her hot wet pussy and pumped away.When all was said and done my sister-in-law said, “I love you. I’ve always loved you.”Then from behind me Debra said, “I love you too.”When I turned around Debra was naked and came. Many other robed society members waited for them on soft sofas, several couples including Jo and Paulo and five or six new couples who were there to see Ann whipped and fucked. Ann noticed that all the females wore wrist and ankle cuffs. The lighting was low and indirect, the walls of ancient stone with modern services attached for heat and electricity. The room was warm and full of bondage equipment that made Ann shudder when she saw it.No introductions or explanations were necessary this.
