The drive to the mall took her twenty minutes in the morning traffic. She was thankful to finally pull into the parking lot. For some reason her behind was feeling increasingly uncomfortable in the car seat.
Mary never heard so many cat calls in her life. Her body was certainly attracting more attention than she was used to. It made her a bit uncomfortable, but it was still good to feel noticed. Oddly enough, the ache in her rear end wasn't easing up now that she wasn't sitting down. She dismissed it for the moment as she entered her favorite clothing store.
She picked out a few bras, wondering what her exact size was. She grabbed the three largest ones and a few short skirts and headed into a changing room.
She pulled off her pants, which took a bit of doing. They were a tad thin for her new sexy thighs, but once she pulled them off a major pain was alleviated. She wondered why her rear had been aching all this time, and now was as good a chance as any to find out.
She gasped as her hands felt something. She turned her behind to the mirror to see what it was. Sticking out from just above her butt was a thin, three-inch mass. It was pointed, about a half-inch thick and light pink in color.
Mary stared at it for a moment before her face broke out in a smile. The mouse vial was working after all. She was growing a tail!
She looked her entire body over, searching for more changes. There was nothing, save the slight inkling that her fingernails looked a tad sharper than they were supposed to. It made sense that she wasn't transforming very fast; though she wasn't conscious to witness it, her change into a Playboy pinup took an entire day.
Mary continued about her business, comparing the bras to her bare breasts. The best candidate seemed to be the largest one, and when she tried it on it was confirmed. Her breasts felt a bit cramped still, but since there were no larger sizes, they were out of luck.
She found some pretty skirts that fit perfectly--tail aside--and picked out some attractive tops as well. She rung up her outfits and left the store. While she was eating some pasta in the food court, her tail's discomfort returned and an annoying itch began from the same part of her body.
After her meal was finished, she ducked into a restroom. Locking the stall door, she pushed down her pants. They were the same restricting pants she had worn all day, but she didn't want to put on anything she just bought until it was washed. That was one of her important shopping rules--Don’t wear it until it’s been cleaned and ironed.
She saw that her tail had grown a couple more inches. It was developing small indents, almost like segments on a worm. The area around where her tail connected to her back was getting fuzzy. Mary also noticed her pubic hair was losing its color.
She hoisted up her pants, realizing that if she changed much more people wouldn’t be noticing her just because of her long hair and large breasts. Mary hurried out of the mall and got back in her car. A thought had occurred to her, however, that she was almost out of food at the house. She wondered if there was enough time to stop by the grocery store on her way back to her apartment before any visible parts of her body began to change.
