I told her to lean farther over, which she did eagerly and I started to pound my cock, all eight inches into her firmly landing my balls against her m...ound with each stroke. The noise of her moans of delight, those of my scrotum slapping her mound, and my own gurgles of pleasure brought her to her first real orgasm and she gushed wetly around my shaft drenching our thighs with creamy wet cum, which ran down to the waistbands of both of our jeans. I continued to pound my cock in and out of her as. "You two will be ok if your mother and I visit my Grandma?" our dad said one Friday morning."Sure, daddy," confirmed Jen."I think I'm working tomorrow," I said, "so it should be ok."I sat at my desk, my mind not on the job in hand but what I was going to do to my sweet sister that very night. Did I have a conscious about it, her being my own sweet sister? Fuck me no, not in the slightest."Fancy a beer?" I asked."Sure," she said.It was almost too easy for she downed the beer I poured for her and. Her hard nipples felt good against my chest… She kissed me again, but now very softly.Then Camilla told me she had a surprise for me; but first she would blindfold me. She brought a black silk scarf and put it around my head, covering my eyes.I felt her naked body riding mine. Her wet pussy lips were sliding up and down over my hard cock. Suddenly Camilla lifted her body for a moment.Then I asked her which kind of surprise she had for me...Camilla got my hands and she tied them to the head. Sam slipped into bed which was the first time Susan and Max even noticed Sam was in the room.Susan turned just her head up to see Sam, reached back to grab Sam’s head and drew her sister’s mouth to her own. They shared a deep sloppy kiss. Sam nestled in behind Susan noticing she was already naked. Her large body was warm and spacious. Sam drew her hands on her sisters ass and legs, then reach her left hand over and cupped her massive left tit. It was huge and squishy. Just the size alone turned.
