Aya was so distracted by the thought of what would happen when she finished writing on the scroll that she unknowing wrote a "D" instead of a "M". But before she could realize her spelling mistake, Aya finished the scroll by dropping a period at the end. After which the scroll suddenly rolled itself up before levitating in the air and then vanishing in a puff of smoke. Aya almost immediately felt it on her flesh, an intense heatwave that made her moan. She cried, undressing , knowing something was terribly wrong as her nipples hardened and she felt an alien throbbing in her shaved crotch. She looked down between her legs to see a flesh pushing out; growing thick and stiff. It was then that an itching sensation spread across her smooth skin as body hair began to sprout without regard to her femininity.
Crying and naked, Aya ran from her room to the bathroom to see herself in the mirror, to see the horror that she had caused to herself. The expanding flesh on crotch had grown into a large penis that hung heavy between her legs, her breasts swelling, not into the boobs she wanted but hairy pecs. Her beautiful brown hair pulled itself back into her head as her face swelled up, becoming way shorter and greyish in color.
Aya grabbed a hold of the bathroom sink as her back expanded wider, while her voice grew deeper and her tiny feeble form was replaced by manly muscles. Her hands grew bigger with her fingers growing thicker and longer and her arms swelling with muscle. Aya could feel her feet stretching across the floor as they grew to larger and hairy while her leg muscles expanded with strength and her cute little ass hardened into a more masculine one.
If one were to walk past the bathroom they would have heard the sounds of the transforming girl as the sounds of her sensual moans gradually turned into deeper sounding groans and grunts.
Pushed and cornered inside her own brain, Aya whined about how unfair it was that such a simple mistake, putting a D instead of an M, could lead to such drastic transformation.
Her thoughts were replaced terrifically quickly by things that she never even considered, that she didn't like, that she hated, but not the man...the man she was becoming. The pulsing and swelling sensation of his muscles growing and the throbbing of his large cock finally pushed him over the edge. With a very loud grunt, his big balls tensed and he blew his load onto the sink in front of him and on the floor below. The man was all that was left.
A little while later, "Dave" came out of the house wearing the clothes he found around the sorority house; a pair of jeans and a white shirt that he hadn't bothered to button up, proudly displaying his hairy chest and slight round belly.
Dave was quite satisfied with himself, there was a new daddy on campus...and he was going to run wild.
