By the time I took my eyes off her legs and hips, I could see she was grinning and enjoying every moment of it.I shook my head and smiled.“I can’t...pee, you’re watching me.”Debbie nodded, walked towards the sink and turned on the cold tap.“That should do it,” she replied.I shook my head. “You’re still watching me.”Debbie planted her hands over her eyes but her fingers were wide open and I could see she was looking straight through them.She stepped towards me.“I’ve never seen a man on the seat. And she was making Haley moan and scream. I lapped up her juices and swirled my tongue around her puffy clit. Her juices were all over my face and her moans were getting louder. I knew I was close to making her cum. I kept on liking and sucking and slurping. She grew louder and louder until finally she climaxed. She bucked and jerked and she came so hard she completely abandoned Haley. I stood up and slid my cok inside of her while she was still cumming. She screamed and bucked. The juices. I hadn’t told her that I was still doing my sister, so I pretended to be outraged. She didn’t know how to react and started crying. I said I was sorry, and finally admitted to her that I had also fucked my sister 3 days ago. Her tears turned to laughter, and at that moment I felt closer to her than ever before. So close in fact that I asked her to suck off her little brother. She gladly took me in her mouth and sucked the cum out of my cock as I screamed my sisters name.When we had a chance to. We had failed to notice the spectacular view from the window the night before. I'm certain that the view at sunset is truly amazing and made a mental note to find out with Beth one day this weekend.We had a wonderful brunch consisting of Chicken parmesan and an excellent Caesar's Salad. As we were finishing our meal I took Beth's hand and brought it to my lips. "Beth we need to talk and I guess now is as good a time as any."The look of uncertainty and fear in her eye's nearly ripped my heart.
