It worked! Adam answered the door in the same loosely tied robe that I’d met him in three weeks ago. He smiled when he saw me and said, “Good morn...ng, Barb.” Then he laughed, put his hands on his hips, and added, “What took you so long?”I smiled back at him and was about to respond, when I noticed that…when he put his hands on his hips, his robe swung completely open. My eyes fell immediately to his cock….every bit as big as I remembered it….dangling impressively between his legs. Long and. Seeing my sister sucking my boyfriend's cock really turned me on—maybe more than it should have. I began to worry that I had gone too far. What if JR was upset when he woke up? What if he started liking, or even loving, Mo more than he loved me? What if I had derailed our relationship just when it was getting started?The more I thought about it, to more anxious I became. I started to draft my apology in my head. While I searched for the words I would use to tell JR I had made a mistake, I felt. Cindy guided Jenny so that she was sitting on the edge of the Jacuzzi and went down on her right there. It wasn’t long before Jenny was cumming in Cindy’s mouth, hard, I could see Jenny’s cum gushing out. It was not often that she came this hard, but this was a once in a blue moon event. When she came, I stood up quick and said “oh shit, I’m cumming” and turned around so I would not shoot my load in the pool, and Cindy said, “there you go boy” as she slapped my ass. Watching Jenny get what. Her body seemed to be shaking as if she was riding a rollercoaster and I could hear her gasping for breath. None of the females I’d had sex with had orgasmed as hard as my mother did that night.I am sure that if I had not been holding her up, by grasping her large breasts tightly, she would have fallen off because her orgasm lasted a long time. My cock was gripped so hard that, even if I’d wanted to, I would have been unable to move it. Then, like a balloon deflating, her body went all floppy.
