Katy got out of the shower, dried off, went to her room, hid the collar and dildo, went to bed nude and fell into a deep sleep. She dreamt of being canine, of being fucked as a bitch by big muscular dogs.
The next morning, Katy woke up early, her sleep uncomfortable. She was lying on her back, and it felt like there was something in the bed, like a small ball or other hard object, right under her lower back. She rolled over and felt the mattress, but it was perfectly smooth. She slid herself on to her back again, and felt the same pressure. This time she glided her hand directly up from her ass to her back to feel what could be under her. Again, she felt nothing but soft sheets—but as she swept up, the back of her hand felt a small nub just above her butt. It also seemed like there was fine hair on her back.
She jumped up from the bed in panic and looked at her naked body in the mirror. She almost broke down in tears as she looked at herself. Her face looked almost normal, but there was a slight elongation to the shape of her skull, her ears were almost imperceptibly pointy at the tops, and her nose was just slightly longer than normal-- and worse, there was a small dark spot, slightly wet, at the tip. As she gasped in despair she could see her teeth—her canines had become more, well, canine. They were noticeably elongated, almost like in vampire movies.
But the real problem was her body. Her feet and lower legs had thinned noticeably, her toenails black, and fine dark hair was growing thickly from her ankles, thinning as it came up her legs and up her back to her shoulders, which had also flattened and narrowed. Her hands, too, had become slightly misshapen, her fingernails thick and black, thin hair growing on the backs. Her chest was flatter than normal, and six little spots—almost like large blisters or boils, but painless—sprouted in two rows down her torso. She knew from her earlier transformations that these were the beginnings of canine breasts.
She sat down and cried for a while as she looked at her deformed body. Even through her despair and confusion, she felt an insatiable sexual appetite growing inside of her. She wanted—no NEEDED- sex. She didn’t know what to do next.
