“You know I love you rose…but….” I was half asleep now too. “But…. you’re my sister, and….” My mind seemed to be loosing focus as I ...elt her breath breeze over my chest. My vision blackened in minutes, and I awoke later. I looked at the clock. it was almost 10 A.M. “Ugh, lucky its Saturday….” I said about to sit up from lying in the bed as I realized something was wrong. My sister was still lying across my chest, but her hand was in my pants and seeing as how it was morning, I had morning. Not only did I make those adjustments but I locked the door too. It wouldn't have been very fun to fall out of the car while in the throes of her ride.The changes in our position didn't go unnoticed. "What are you two up to?" Jeri asked."Just trying to get comfortable," I answered. Just like not wanting to fall out of the car, I didn't want Jeri distracted from driving and getting into an accident."There better not be a mess back there when you're finished," she replied.She was good, or else. He once again felt her frothing and looked between them to see his foam-covered cock each time he withdrew. He heard Marge scream as he was looking. His eye caught the view of a liquid spraying upward from her cunt. He fucked downward splattering it between them. When his balls smacked her ass, he came. He spurted, sprayed and then dribbled until he was empty.John passed completely out.Marge rolled John off her. She walked over to her favorite seat with his cum leaving trails down her inner. I asked her i was better at being a master of sex too and if she would agree to do whatever i asked for and she was ready. I asked her to tie her hair into a bun tight and asked her to remove her gown. Now i was in my underwear and she in her bra and panties. Her boobs were large and just perfect i wanted to roll my penis between themI shut the door , started a bit of music as i wanted her to scream and moan due to the trysts in her cunt.She now looked a million dollars but i wanted her to be.
