He gives me a quick comradely grin. "would you like to try the next dance?" I don't even know what the next dance is." I admit."Oh good," He sounds re...lieved. "because if you said yes I would have to talk you out of it." he takes my arm and leads me away from the center of the room."You don't like this dance?" I ask."The truth is I'm not much of a dancer." he admits to me with a rueful laugh."I would have never guessed." I laugh back at him."I guess, I just never got into the whole dance until. Another little modeling move and she lay back down next to him. He looked at her and couldn't help but ask "have you ever?" and she nodded and said "yes, twice". Then they were kissing again, his hand now free to roam without anything between them and her body. Soon she was trembling and, rubbing his cock through his shorts said "your turn dad". He quickly removed his shorts and heard her gasp as she saw his cock unfettered for the first time. Then he kissed her again and slowly worked his way. I opened my eyes and saw that Debbie had come over and sitting down next to me, had started kissing me while Joan sucked on my tits. "You've got such beautiful tits" Debbie said to me as she broke off. By now Joan had moved down and taking hold of my skirt, began to pull it off. I rose up enough for her to slip it off and since I wasn't wearing any hose, she took hold of my panties and off they came as well. Debbie moved down a bit and started sucking on my tits as Joan spread my legs apart. I then quickly got up and turned to look at dad.He raised the cup quickly to take a sip. But I knew he looked, as I could see a tent form in his trousers.The sight of that made me so fucking wet; knowing that he had an erection looking at my pussy and arse. I controlled myself as much as I could and sat next to him on the sofa. We watched TV together as I snuggled into his arm. I made sure that my breast touched his arm every now and then.I only watched part of the film and made my excuse that.
