I immediately noticed a woman in her upper twenties looking over at us. She was gorgeous looking as she had nice big beautiful tits. She had a pair of...tight jeans on and she was making her way right for us. I tried to get Alex’s attention to stop, but he wouldn’t as she came closer and closer to both of us. His cock had felt so good inside me as I really didn’t want him to stop at that point. A few seconds later I looked up to see this gorgeous gal right next to us. I felt her hand pull up my. “Mmmmm!” he replied, nodding his head.She stood and watched her son suck her piss wet panties, his fist gripping his cock hard. Her cunt lurched, and her clit throbbed with a tight, hard knot. She lowered her face to his, and brushed her lips across the soft panties dangling out of his mouth. She tasted her own piss, and her cunt sucked inward with heat. She opened her mouth and sucked at her panties too. Her eyes burned into those of her son as she tasted hot piss, her hand shoving his hand. Michelle was expecting to either see Stacy collapse onto the bed or better yet, start to fuck Rich and so she couldn’t believe what she was watching as she saw Stacy slide the cock sized vibrator into her vagina and another smaller one into her ass. At first Michelle was shocked but the sight and sound of her half sister giving herself so much pleasure in order to please her lover continued to excite her. Michelle’s body was a mass of pleasure zones, her nipples were hard and her wet fingers. Or worse, what if he thought I did it on purpose. I couldn’t even look at him. We finished the end of the movie, and we both just sat there. Eventually, Uncle Benny got up and stomped into the kitchen. I heard him putting ice into his glass and then, slam the freezer door. I didn’t think it was my fault, but part of me wondered. Did I do it because I was curious? He came back in and sat down. ‘ I’m sorry Uncle Benny. I am SOOO sorry.’ He looked at me like he didn’t understand a word I was.
