The first thing Terra noticed was that her breasts weren't growing. Oh well, she thought, maybe it takes a little while, then she noticed she was taller, and a little more muscular. "What the..." was all she could get out before she was forced to her knees by the strange sensation that gripped her entire body. Looking down she saw her bee-sting AA-breasts disappear entirely as she felt a strange stirring between her legs. Terra managed to get up to a kneeling position and looked in the mirror. She noticed her hair was much shorter than it had been, and her body had lost any shape it might have had. Her vagina still felt funny, and in a moment she knew why. Her clitoris had more than doubled in size and was steadily getting longer. She watched, helpless, as a penis slowly grew out of her vagina and it closed up. She then felt something strange near her stomach and felt her ovaries descend and become testacles. After her 'equipment' had formed, Terra was able to move again. "Oh my god...I'm a boy!" she said, noticing her voice had changed. Okay Terra, she thought, don't panic. She'd always wondered why the boys at her school were so uncomfortable with puberty. Ever since they'd watched the sex-ed video, the guys had been really weirded out every time a girl walked near them. "Hmm..." She went back and got the blue pendant, walked back to her mirror, and put it on. Immediately, she started getting taller. Terra watched as her legs got longer, more muscular, and started growing hair, and her shoulders widened and became more manly, but what really caught her attention was what was happening between her legs. Her penis, which had been about 2 inches long and very thin, was growing. First, she got an erection which was an interesting experience all on its own, then she felt her engorged penis swell, growing longer and thicker as she watched, stopping at about 6 inches long and over twice as wide. "Whoa...how is this thing supposed to fit..." she said as she grabbed it. Wow, she thought as she started pumping her hand up and down, this feels great! She kept masturbating, thinking about herself as a 19 year old, and suddenly she came, startling herself. Terra quickly got some kleenex and cleaned herself off. "Well, that's quite enough of being a boy!" she said, and took the red pendant off. She was doubled over again as she watched her 19 year old male body transform into her 19 year old female body. Her hair got longer as her penis shrank quickly and was pulled back inside her as her hips and ass swelled, her legs got curvier and shorter and lost the hair, her torso lost its muscle and her waist shrank as her nipples tripled in size and her D-cup breasts exploded out of her chest. Terra got up, shaking, and put the red pendant back in the box. "Well...what should I do now?"
