I couldn't find it where I bought a Playboy. One day afterwork I knew of an adult book store a few miles from work but on my wayhome, if I drive thro...gh the city.One day I parked and went in. It was my first time in such a place. Isaw a rack with Playboy's and Penthouses, and then saw the Variationsmagazine, it was a smaller publication, not quite pocket size more like areader's digest size book. I grabbed one, a Penthouse, Playboy and thenstarted to walk around. Yes, I was nervous as this. I open it. Brenda’s standing there. For a moment my eyes explore her, lingering on the outline of her white bra visible through her well filled blouse, and her bare tanned legs. She looks flustered, as if she’s worked up about something. Before I can say a word, Brenda speaks.“If you show me your cock I’ll take all my clothes off for you.”I stare at Brenda, hardly believing what I’ve heard. As if anticipating my answer Brenda lifts up what little there is of the front of her skirt. We boys all. She started sucking on it. I grabbed her head and pushed it deep on my cock. I started pissing and told her to drink it all. She was drinking it and drank every bit of it. She continued to suck my cock. I was spanking her with a whip. Once i was fully hard, i told her to ride me. She said "Please no more my pussy hurts" I slapped her and she got up. She sat down on my cock and started riding it. I was sucking on her tits while she was riding me. She rode me for sometime then i turned her over. Her sentience wasundeniable. She was intelligent right out of the box,but watching her grow emotionally was quite amazing.She once asked me why I was so good to her - afterall she was "only a machine." I told her that she wasmuch more than that and, after all, I was a machineas well... a biological machine. As the years beganto take their toll on my body, she becameincreasingly disturbed. She studied medicine,genetics, bioengineering, mechanical engineering,nano-technology - virtually.
