Slow

David waited, but nothing was happening. He thought that it was a botch. So, he went to his recliner chair. He wanted that serum to work so badly, he finally met a girl that he liked. He thought now his chances with Monica are over. As he went to scratch himself, David realized the hair on his arm was gone.

"Shit! Did the serum cause hair loss?" He went to feel the top of his head, and his hair was still there. Then it got longer. "What's happening" he asked himself. Then he felt his dick suck into his body. Now he thought he was loosing it. Then his hips caved in. This was the most pain David had ever felt before.

He quickly made his way to the bathroom. Then he started to grow tits and his ass got bigger. His hair then turned from black to dark brown. His skin became darker and then his face became tingly. The bones in his body rearranged themselves and eventually David passed out.

When he woke up, he went straight to a mirror. "Shit, I'm a woman".
