K. with this." She put her hands to the waist of her shirt and took it off. Dawn did the same thing. In a matter of seconds, mother and daughter were ...aked and Keri was pulling off her husband's underwear."Dawn lay down next to your father. Dan scoot down a little." They were finally where she wanted them. "We are going to be a threesome from now on. We are going to have sex together." She lowered her breasts near their faces. "I have always wanted both of my nipples sucked at the same time.". Surprisingly, Crystal made it there with no problem and was able to plant kisses all over and in her mother's crotch over panties which was surprising in itself, made more so by the fact they weren't alone. The four other kids were in the same room watching. The most surprising thing of all was when her mother shrugged off her robe and stood wearing only panties. Since Crystal had crawled out naked, this made for a very shocking and very lesbian scene.Her mother seemed to want crotch kisses. We took some lunch to the apartment and opened a bottle of wine. I was told that I could have one glass as I had turned sixteen the previous winter. I had a small glass and felt a little woozy.After lunch, Mum went off to have an afternoon nap. Step-dad and I stayed on the balcony. It was private and we started chatting. He was in his swimming shorts, I was in my bikini bottoms and had pulled a white crop-top over my bare titties (what little I had at that time. I had been topless sun-bathing. "That's it I'm calling security." I say going over to my phone. "NO the fuck you not!" Apparently he was not as drunk as I thought cause the next thing I know I'm pinned up against the wall hard from impact. Suddenly he seemed bigger then me....He was up close and personal on me, his breath had a heavy alcohol stench. He spoke to me in a low tone voice and his speech was clearer then before, "I know he's been up here. I saw the two of you leave the party. I saw yo' fuckin ass all over him.
