"I've got to get you out of here without my parents noticing," he explained as he slipped the collar around her furry neck. "But something tells me that's not going to be difficult." Derek pursed his lips, his eyes lingering on Sonya's delicious body. "You know...maybe we don't need to get you out of here." He smiled and the solution came to him. "But, my tigress, you can't stay like that." Pulling himself up in a commanding pose and waving his arms in mock-dramatic gestures, he said, "Sonya, you will now shrink down to a foot tall and become a plush toy version of yourself."
"Mmmm...OK," Sonya purred, then her yellow slitted eyes opened wide. "Wait? What! A toy!" But before she could utter another syllable, she felt the changes beginning. Everything started looking bigger, the bed, the room and Derek. It was one thing to grow fur, but this was a much odder, Derek's normal sized room was becoming a whole new world to Sonya. Now she knew what Alice would have felt like, drinking that bottle of mysterious liquid. Curious. As Sonya reached the minuscule size of one foot tall, she still looked like her tigress self. But not for long. "Derek!" Sonya squeaked up at her boyfriend.
"Sonya!" Derek sat down on the bed, still amazed at the power of the collar, and rapt, watched Sonya's next change. It wasn't obvious at first, but it soon became apparent. Sonya was getting fatter, and she noticed it. Paws explored an increasingly soft and large belly and soon the rest of her followed. She was plumping out, becoming a plush toy. Her arms and legs swelled with filling and shortened. Sonya collapsed as her legs gave out and grew perpendicular to the rest of her body. Next her paws merged with her now stubby arms. Finally, her face and neck stopped moving and a forced stitched smile pulled itself over a cute button nose and under yellow bead eyes that caught the light in a mesmerizing way.
The transformation over, Derek picked up Sonya. She was a toy, light and full of nothing but cotton. But she looked amazing, as a cartoonish version of her tigress form and with the collar fastened around her neck. He stroked the fur, and moaned, it was so soft and luxurious. He couldn't help himself and hugged Sonya tight, nuzzling her face and whispering into her large tiger ear. Setting her down on his bed, he went out to talk to his parents to keep them away for a bit. He'd be back in no time.
