Sandy lay back on the bed, waiting while Frank quickly undressed and came down beside her. She spread her legs open as he began to fondle her cunt, st...oking his rigid cock as they kissed again. No further foreplay was needed, of course, and he moved onto her and she directed the cock into her cunt. Watching them, as I lay there on our bed, was like watching a porno film. However, it obviously different knowing that it was my wife on her back with her legs spread wide welcoming him into herself.. Nancy's head took a dive into the tub and came my way. "Have I not fulfilled your needs, Celia?" she asked, just before kissed me. Sweat still flowed down my head as my nerves were shot. Then, her right hand floated over to mine, and I took it. She helped me up out of the tub, and I stood only a few inches in front of her. "My step sister, really? If you wanted a threesome, well, she would be a good choice, but you should have asked me about her. She is a sexy young woman at eighteen. Did she. . I-I can't! I can't give in to them completely! Oh God, How did I-I get into this?The bed sagged as her brother stretched out on the other side of her. She knew by the contact of his body as he pressed up against her that he, too, was now completely naked. She could feel, distinctly, the outline of his rock-hard penis made on her own warm thigh.Charity just couldn't believe it; this couldn't be happening to her. What was left of her reasoning mind tried, halfheartedly, to sort out her confused. "Where are we going, Master?" I asked after we had been travelling for around twenty minutes. I realised it had taken us nearly four hours to drive from his house to Mistress Gina's... surely he wouldn't make me wait that long... "You'll see." was all he said. I began to become impatient, but I didn't dare say. I was in enough trouble as it was I realised. I distracted myself by thinking of what he would do to me. He would punish me surely... I felt my pussy getting moist again as I imagined.
