"Huh?" She said as she reached up to touch it. The disks felt warm to her touch but were quickly cooling. 'Didn't I take this off?' she thought, as she tried to lift it off over her head. Terra was shocked that as the necklace reached the level of her chin, it passed through her fingers and stayed around her neck. Terra began to feel uneasy. She liked her body the way it was now, but what would everyone say! She had only wanted to START filling out, not become a fully grown woman instantly! She calmed down by deciding to stay in the shower until she figured this out. Her mom never bothered her in the shower, so she figured it was a good place to experiment. As Terra stood under the water again, she remembered that she'd said "I wish I would just grow" right before she'd noticed that she actually WAS growing. Excited, Terra closed her eyes, concentrated, and said "I wish I could change between my normal self and my grown up self whenever I want". Terra opened her eyes and looked down at herself, willing her mature body to become the younger one she was used to. Nothing happened and Terra started to panic, but after a few seconds she started to change back. Terra watched her breasts deflate back in to her chest with a mix of relief and regret. She felt a strange sensation between her legs and she saw the hair there get pulled back in to her. She also felt the strange sensation inside herself of her vagina and uterus changing and shrinking from their mature childbearing form back to her immature form. As she got shorter, she ran her hands over her flawless hips and ass one more time and felt them lose their shape and become the flat, narrow ones she was used to having. Terra now had a few guesses about what the crimson necklace did, and she was eager to discover if she was right. Terra got out of the shower, dried off, and went to stand naked in front of her mirror. She grinned: time to find out if she was right.
