“Actually, Lisa was blackmailed, extorted, into sex with Tammy’s birth father, Nahum Adler. Who just happened to be my biological father, too. Yes..., that’s right. Tammy is my sister and I love her, just as I love my other two sisters, Becky Adler and Leah Finkel. Both of them are Jewish. Tammy is only half-Jewish, of course, not the half that traditionally counts, of course. In any case, she only slept with Nahum in the mistaken belief that he would not only terminate her, but also get you fired. But that was only the beginning.Mandy had picked out the rest of her outfit to accentuate her figure and to show off what a hot sexy well-rounded body she had. And one thing I quickly noticed was that Mandy had lost even more weight than the last time I'd seen her. During our previous sexual liaison of several weeks in a row of fucking, Mandy had obviously gotten serious about the 'baby fat" she was carrying and she'd made a concerted effort to lose some of it. It had been immediately obvious. Following their progress down the street, I realized why she was in that neighborhood as she turned up a driveway another block up, which I could only tell by the reflective material on her running gear. Still thinking about her ass as I plodded along, I figured that she’d probably be jumping into the shower after her run and was envisioning her stripping off her running clothes as I arrived at the driveway I’d seen her turn down. I paused for a moment, looking at the ranch-style house while. I love you." She paused, then grinned and added, "Can we do that again?"I grinned back. "Absolutely." It did occur to me about then that I hadn't considered and she hadn't mentioned protection, but as I'd filled her pretty thoroughly it did seem the point was moot just then, so why worry?She twisted round and dived to take me in her mouth. I winced inwardly, thinking about how she'd come to know what to do, but grabbed her hips and lifted her over me so I could get at her pussy with my tongue..
