Robinson wanted to turn me into a lab rat, run tests, the whole nine yards. Studying me could lead to the kind of scientific breakthrough that would d...fine her career. If I got horny, I could turn her into a sex starved nympho. But any other moment she was clear-headed and a driven scientist whose academic ambition really outweighed her attachment to me.Still, I put up with it. To me, Mrs. Robinson was still the most gorgeous woman alive. I had wanted her for so long that I was willing to be. She nods.“Well next time you cum…if i even give you that chance again….you ask my per….MISSION!” i said loudly grabbing her face, going nose, to nose with her.she again, nods, a tear falling across the bridge of her noise.I look down at my dick, that was still rock hard. “Do you see this.” i said pointing at my dick, “It look like your actually worth something.” i said laughing, before wiping the smile from my own face.I take the Gag off her, “Is that mouth streched?”“Yes Master…” she says“Open. I glance quickly over towards my sister, who is also as engrossed in the movie as I am now, and notice upon doing so that she too has shifted finding a more comfortable position, sitting now on one leg, the other bent at the knee, but I notice too that her hand seems to disappear down between her legs. "Is she masturbating?" I wonder, thinking then just as quickly that surely she wouldn't be, not in front of me anyway, and that it is simply my very aroused over-active imagination running amuck. Next, straightaway, not letting the opportunity go, I asked her if we can spend a night together someday. We both were quite straight forward in our conversation and She said yes and that made my little brother instantly stand up. I cooled him down an it was time to leave for the day. I had to drop her to BTM Layout. She invited me to her house and I quietly went inside as well. I held my horses and controlled not to fuck her on the same day. It was already 10:30 at night and she said she had.
