Well, it all started two years ago, when me and my girlfriend at the time received something called the Chronivac 4.0 in the mail. We had no idea what it was, bought it liked like a program that could transform people into other people or objects.
Of course, we didn't think it was real. We just thought it was some stupid gimmick. For a laugh, we agreed that for one day, we would each transform into a person of the opposite gender. So she programmed in all the characteristics she wanted as a male, typical 6 feet tall, broad shoulders, muscular - the real jock. And typically, I programed the big breasted, blond haired bombshell with a slightly adjusted libido.
To our amazement, it actually worked. There she was, a hot, nineteen year old guy who liked like the star of the college football team. Then there was me, the small and petite woman with a sexy body and a cute smile. We both agreed on no sex, but anything else was free reign, and we would meet back at our apartment at 7pm.
Always the go-getter, my girlfriend - Zoey, left in a rush. I took a quick look at the Chronivac again and programed in some more suitable clothes for me to wear, choosing a black dress that revealed plenty of cleavage and stopped just above mid thigh. It was sexy, bordering on slutty, by I thought I'd only get this chance once, so I would give it a go. I also program in a pair of heels and adjusted my profile so I knew how to walk in them, and decided to forego the bra and panties, thinking they were overrated.
So I spent the day as a nineteen year old girl, enjoying the way I could tease guys and make other girls jealous, but after classes was when the real fun began. I went to the campus bar and met a guy. He was really sweet, and very hot (I mentioned I adjusted the libido) but I remembered our agreement of no sex. Despite that, I found myself agreeing to bringing him back to my apartment. Maybe it was the few beers I was having, maybe it was the libido, either way I found myself hanging off his every word, and when he first put his hand on my leg I felt a wave of pleasure slap me in the face, like a jolt of electricity hitting me.
The evening wore on, getting to 6pm. A few more beverages had been consumed by then, and I found I was now very malleable. After a bit of convincing, I was sandwich between the wall and his rock hard body as we made out. His hands roamed my body, touching me in places that caused me to moan. Then he turned me around and slipped the dress off my shoulders. One hand kept me in a world of pleasure, while I could hear his other hastily unbuckling his belt.
"I shouldn't..." I moaned weakly.
"Shhh." He whispered in my ear, and then I felt something gently slip inside me.
With a soft gasp that turned into a moan, I realised I had been penetrated. "It's alright. Just think of my cock, sliding in and out... in and out... feels good doesn't it?"
"Uh... uh-huh." I moaned, no longer capable of coherent words.
I knew this was wrong. Not only wrong, but dangerous. Zoey would be home soon, and if she caught me like this I was a dead... uhh, woman. Still. It felt so nice. All I could think about was the way his hard cock was pushing deep inside of me. Then, when I couldn't take it any longer, I spun around and we fell back on mine and Zoey's bed. All sensibility was thrown out the window, I was now a sexy, blond nymph wanting desperately to be fucked. And I was. It time I had sex as a woman, but as Zoey walked through the door to find me naked with this stranger, it was destined not to be the last.
First she looked shattered - I will never forget that face. Then a look of pure anger fell over her and she stormed into the next room, reversing her changes and then typing furiously away at the Chronivac. With an evil, triumphant grin she pressed the final key and I felt a strange feeling pass over me.
As I lay in bed, the sheets on my chest rose as my breasts got bigger, I could feel the rest of my body changing to. But that was nowhere near as disturbing as the feeling on my very mind change. All of my regret was fading, quickly being replaced by a lust. An huge lust, so bad that I knew I had to be fucked soon. I was horny, horny and sexy, and that was all I could think about.
With a wicked smile, Zoey spoke her final words to me. "Enjoy your new life, Kelly, you slut." She laughed cruelly as threw the Chronivac from our fourth story window before walk away, but I couldn't care less. I was already moving under the covers to find the sleep strangers manhood. I was trapped as a sexy, cock-craving woman, but I couldn't care less.
Later, after my raging fit on horniness wore off, I began to think straight again...
