Shannon said she wanted to stop at the grocery store for a few thing and since I needed more items to make the lunch we did some shopping. Shannon wan...ted to be prepared so that after we got to her house we wouldn't have to go out again. We stopped for some wine and I bought some bottles of my favorite wine, she hadn't tried it, and we were on our way back to Shannon's.When we got to Shannon's, unloaded the car and I fixed our lunch, pretty much a fresh pesto and pasta with a glass of wine. I. Cathy broke the kiss long enough to mutter, "Stupid fucking bitch! Why doesn't she go back inside" and she went back to frenching me. A minute later she grabbed my left hand and put it on her breasts."Come on Robbie, we're hot for each other remember? Give her a good show."So there I was on the back seat of my car pawing my sister's tit and she's frenching the hell out of me and suddenly Cathy decides that it isn't enough. She decides that Harriet needs to see us fucking. She broke the kiss,. And fucked her harder again, which caused her to moan.She licked at her lips and tried to appeal to his common sense: "Look since I feel kinda newborn, I'm not willing to die in the next time. So I promise I'll do everything you want and you just keep me alive. And everythings fine.!" Bitch!" hissed the hostile voice, but his companion smiled somehow agitated of the thought of having a willing girl around. At least a good alternation to the arses of his fellowmen. But still he didn't trust her. I began to stroke his dick up and down slowly, keeping a steady firm grip. He let out an approving moan and shifted further down the seat. I looked back up at him, he smiled and gave another nod to his dick, and that was all I needed. Slowly I leaned over until his dick was right in front of my face. It looked even bigger so close to my face, and I licked my lips. "This is it" I thought, as I opened my mouth and took the head into my mouth. I kept a firm grip on the base as I felt his dick move.
