Something about the drug was making me think like a girl and have female desires. My big breasts were straining at my thin tank top and I could tell m... nipples were at full attention. Halfway through my drink a cute guy asked me to dance. I accepted and once on the dance floor my new female self took over and I moved just like a girl and rubbed my ass right up against his crotch. He had his hands on my hips as we ground into each other during the song. When it was over he asked me my name and I. “Frisky Fanny” I said, “interesting, how did you come up with that name?”“Well that’s for me to know and for you to find out” she replied with a big smile.“Ah, a challenge, I like it”. “So let’s see; I had never any doubt about the frisky part. Your playfulness, your energy and liveliness are kind of obvious; after all you were performing on stage. Fanny could be a bit trickier”She looked at me with anticipation.“In Britain, fanny refers to the female genitals so if I combine the two, I have to. I would be as flexible and agile as any world-class gymnast. When someone was going to physically attack me, whether I was aware of it or not, (I have always liked Spiderman's Spider-sense) my thoughts and reactions would speed up to double the normal speed. My body would maintain the appearance and form of a man 6' 1" and 225 Lbs but my body fat would never exceed 6 - 8%.Additionally, I would be immune to all forms of virus, bacteria, disease and toxin. In other words I would never get sick. I was sucking on her nipples, which were now hard, nearly 3/4" long like a pencil eraser. Every time I would lightly bite her nipples she would squeal with delight. Soon she was rubbing my stiffening cock and my fingers were exploring her still, very wet pussy. I climbed between her legs, as she lifted them to let them rest on my shoulder as I took the head of my cock and rubbed it up and down her juicy slit. Every few seconds I'd slap her clit with the head of my cock. Every time I did this.
