The 4 of us were in the hot tub talking. Both Mom and Jenn were wearing a red two piece swimsuit which was provided by the staff in the hot-tub. We ha... formed an amazing connection with the 2 of them. They were also both very attractive which made Mom really excited. They said that they weren't having much sex with one another, as Mark was having erectile dysfunction problems. Mom said she could help him with that."Let's go! Let's play!" Mom commanded as she made her move, got out of the hot. When her climax faded into aftershocks and she could take stock of her surroundings, she heard his labored breathing beside her."How was that?" she asked, stretching in satisfaction."My God. Karen!" he swore. "What's going on?"Concerned, she asked, "What do you mean?"He showed her his back. Lived marks decorated his skin. She touched his back and felt afraid. How had she gotten so carried away? She apologized, was apologizing, when he put his fingers to her lips."Don't sweat it. I'm not. Eventually he worked his right hand around and started caressing her pussy under the tight dress. Soon I could actually see Anita struggling to control her building orgasm as that black bastard finger-fucked her cunt out there…Then they both came back to the table for another drink. Anita’s face was red and I knew she had got an orgasm from that fingers.The sexual tension became more intense as they all now took turns dancing with her. They began moved their hands on her body, each of them. By the amount of it, this wasn't the first guy to fuck her tonight. She was holding one guy's dick on one hand, and sucking on another one. When she saw me come in, she released the dick in her mouth and said to me, "Come on in. The more the merrier!"The guys around her cheered at that, and she gestured for me to come into the room. Then she took the dick back in her mouth and began sucking. Tim told me to get undressed and do her. I had heard of group sex before, but this was Linda. She was in.
