Sandra was suddenly eager to join me on the floor and as she pulled away I caught my first proper glimpse of Terry's erection. It was bold and stiff a...nd slick with fanny juice as it sprung from a thick thatch up to his belly but I could tell its dimensions didn't equal mine. Before I could continue my comparison however a delicious sensation overtook me as Sandra lowered her warm mouth to my helmet.I lay back, let the dope and the Sandra's mouth do their work and thoroughly luxuriated in it. He sits down on the sofa and says ‘let me have a good look at you slut, give me a twirl, I want to see you in your sexy tight black dress’.I stand in front of him, and spin around a couple of times so he can get a good view of me, he tells me to pull my dress up so he can see my ass, I do as he tells me, he tells me I have a nice ass, he then tells me to come and sit on his lap, I pull my dress back down covering my ass and walk over to him and sit on his lap, I put an arm around his shoulder,. I then led him into the bedroom and sat him in the executive computer office chair which I had wheeled in from the computer room, and tied his arms down, and slipped a blind fold over his eyes for a few minutes while I got out a few things. I taped one to the head board over the bed, perfect view for him, I also set a pillow or two at my hip range on the bed to bow my hips up for some very deep stroke fucking. Then I placed a dildo or two and some lube on the bed, and then I placed a pillow at. I reached up and played with her tits. I could feel Kim’s hand on my side. I squeezed Keri’s nipples. She had another orgasm. She whole body shook. Keri continued to ride my cock. She was completely enjoying this new experience. I looked at Kim and said, “bring your hand between us, put your finger on your sister’s clit.” I watched Keri’s face, we both could feel what Kim was doing. The second Kim’s finger touched Keri’s clit, she had another tremendous orgasm. Then she collapsed on top of me.
