Amanda stood in the mirror, still transfixed on the penis she had suddenly acquired not an hour earlier. The fleshy organ stood from her crotch as naturally as if it had always been there. As she gazed down on it, she could begin to feel a tingling feeling surrounding it as, odd as it was to think such a thing, her balls started to pull in closer to her groin. At first she thought that maybe the organ was shrinking away, but that quickly changed as she looked on in horror. She began to feel a wave of numbness spread all over her body, as if pulsing from from her groin. Moreover as Amanda felt these waves, she could feel changes to her body start to creep across her skin following them. Muscles started to bulk up along her arms, legs and abdomen, as if she was getting stronger by the moment.
"Wha...*ahem*...what the fuck?" Amanda grasped her throat, as it suddenly felt dry, letting out a raspy and deep baritone voice. To her horror she felt a lump start to grow in her throat, her mind registering it as an Adam's Apple, something that definitely shouldn't be there. As if a switch were flipped in her mind, she realized that instead of her body rejecting the penis, her body was altering to match it. In short, she was turning into a man. Almost immediately as she realized this, she felt the strange sensation of her body growing taller, adding nearly six inches in height while muscles continued to shape themselves over her rapidly masculinizing frame. Her hips narrowed as her shoulders broadened. Her hands and feet grew larger as her skin grew more coarse. Her own hair began to shrink back into her head, forming a short masculine style, even as hair appeared in small smatterings across her face and body. Her face became far more handsome, cheekbones and chin becoming far more pronounced in a matter of moments. She groaned in her newly acquired baritone as her dick grew in response to the raging hormones in her body, even as her breasts slowly shrank down into her expanded chest, merging with her pronounced pectoral muscles. Absently, she began stroking at her dick as it returned to its erect state, and before long she was experiencing another male orgasm, her...no...his cock shooting a massive load onto the bathroom floor.
Amanda could only watch partially in horror and partially in awe as the tingling feeling subsided and he felt normalcy return to his newly transformed body. Before he could even think on what had happened, he could hear a knock at the front door. What exactly was he going to do now?
