Before Katie could recover from her first male orgasm, she started to notice a strange tingling sensation around her crotch before a rush of energy and sexual excitement overcame her senses.
"Tiff…I feel kinda strange-" was all she could mumble before the changes began.
Katie felt an inching around her groin. Looking down, she noticed her once thin pubic hair was growing thicker and more dense around her new male equipment. It quickly began spreading outwards and she could feel her legs itch as dark dark began to grow on her still feminine thighs.
"Tiff..whats... happening to me?!?" Katie exclaimed. Her recently shaven arm pits began to sprout hair at a very rapid rate, getting longer and thicker, well beyond what she naturally had.
"Katie” Tiff said softly. “I think you’re becoming a man!”
"Oh god! It feels...so strange..." she uttered, placing a hand on her throat where a light pressure was starting. An Adam’s Apple was beginning to form, the slight lump slowly becoming visible on her neck. Her once modest breasts were dwindling, her nipples shrinking.
Tiff could only watch as the feminine features of her best friend vanished before her eyes. Even Katie’s face was changing. Tiff could tell her friend’s eyebrows had grown thicker and that something had changed in the shape of Katie’s face.
Katie watched with a mix of horror, arousal and excitement as the fine hairs on her arms thickened and grew. Her forearms ached as they stretched longer and expanded slightly with an added muscle mass. Looking down at her body she noticed that her hips seemed to narrow, fat vanishing from parts of her body as stronger muscles took their place. She could even see the start of a six pack appearing on her abs. A trail of hair began to creep up towards her belly button. Katie watched in disgust as it quickly went from a few stray hairs to a dense trail of black, wiry hair.
Her legs started to ache next, thick black hair was rapidly covering her legs while they began to lengthen. She was growing taller too. The ache spread to her back where she could feel the same sensation, the slow stretching and pulling of her body. The hair on her stomach was continuing to climb up, growing past her navel and hiding most her new, fully formed six pack.
Katie started to scratch her chin and upper lip as the familiar itching sensation signaled the start of facial hair. She could feel the itching as more hair pushed out of the follicles on her face and extending down to form sideburns.
"Oh, Katie, you really are turning into a man!" Tiff cried.
"I know!" Katie exclaimed, her voice cracking in the process. "She shrieked at the sound of her changing voice and reached a larger hand towards her lips. There she felt the bristly shadow of a rapidly forming beard. She was in shock. Looking down, she watched in even greater disgust as hair began to appear on her chest.
"No! No! This is gross! I’m getting all hairy and gross!" She exclaimed her voice now clearly that of a young man. Facial hair was now covering her jaw line, up her his cheeks and down to her neck.
As hair began to spread over his chest, Tiff began to notice just how Katie's muscles had developed on her arms and chest, and how her friend now had the lean body of a runner or swimmer. Katie pushed her hands over her torso, ashamed of the hair now beginning to cover her chest.
"This is disgusting! I can’t believe this has happened to me!” She said in a deep baritone voice and stared transfixed, horrified as her torso became more and more hirsute. Katie was now a furry young man, indeed. Swirls of hair covered her chest completely, extending up to the base of her neck, near where her now very full, but short beard began.
"What am i going to do?!?" She cried. "I’m disgusting! Look at me! I look like a guy!”
But Tiff was not disgusted, as she looked at her now naked, tall, hairy, and fully masculine friend, she was more than a little aroused by the situation. Her mind began to think of what to do next.
