Mary stood in the kitchen, cleaning up the empty pizza box and drumming her fingers on her udder. It still felt like there was some milk in it, and for some crazy reason Mary wondered what it tasted like. She got out a glass and, after undoing her robe, brought it under one of her teats. She squeezed a few times, filling the glass to almost halfway. She swished the milk around, noticing its creamy consistency.
She brought the glass to her lips and downed the milk. It was warm and thick, but didn't taste very good. It was a little bittersweet. "Gah!" she sighed after swallowing it hard. "Guess that was a bad idea." She rinsed out the glass and put it in the dishwasher. Then she began to feel strange.
It was like the floor was getting closer. She had trouble balancing for a moment as her vantage point dropped a little. She was getting shorter! She grabbed onto the counter to keep from falling over. Fortunately the disorientation didn't last long. When she was feeling better, she walked quickly to the bathroom and looked in the mirror.
Staring back at her was a face she hadn't seen in years...almost a decade, in fact. She looked like a teenager. Her horns had actually shortened a couple inches, though they were still there. Her bra felt a little looser as well. As she felt her smoother face, she saw that her hands were different too. Not exactly a teenager's hands...they were covered in white fur, and two of her fingers were missing. She looked at the more carefully. The fur stopped just past the wrists, and her two remaining fingers were thicker than before. Looking down, she saw that her feet were different, too. Her toes had merged into two large stubs with black tips. White fur grew on her feet as well.
"I'm...I'm younger! And a little bit more cow?" She was surprised at what her own milk had the power to do. Maybe it was yet another side effect of the strange vials. It had to be. Milk was designed to be drank by young calves, so that what it tried to turn her into, except she hadn't taken enough of it. "But is there a way to get back to 25?" she asked herself.
