Mikey wasn't sure if he had to have something specific in mind, so he said, "Sheila will change so she has no problem having sex." No changes were immediately apparent, so Mikey put the dictionary away and sat down to wait for Sheila to emerge from the bathroom.
Sheila had run upstairs because she didn't want Mikey to hear any noises she might make -- and because she knew there was a relatively comfortable chair in the upstairs bathroom (more comfortable than a toilet, at least), in front of the table where Zoe sat to apply her makeup. Sheila could see how red and flushed she was in the mirror in front of her as she sat, one hand inside her panties and the other inside her tank top rubbing one of her breasts.
Working furiously, she could feel herself on the brink of coming, and then suddenly she slowed down when she noticed something strange -- the peach fuzz hair on her arms was shrinking, disappearing into her skin. And on that skin, her freckles were enlarging, growing together to form a nice, even tan. She felt a twinge as she poked her breast, and removed her hand from her tank top to reveal that her fingernails were growing before her eyes; they quickly lengthened to about an inch past her fingertips, perfectly manicured with frosted white tips.
At that point, she could feel her body stretching. It was growing out of the confines of a petite 14-year-old gymnast and becoming what could only be described as "voluptuous." She was putting on weight, but it was all going to the right places: her legs lengthened as she gained womanly hips and thighs and a rounded ass that strained her skirt almost to the breaking point. As her breasts swelled to the size of large melons, the bottom hem of her tank top crept up to show that her stomach remained flat and her waist remained narrow.
As Sheila looked in the mirror, she first noticed that her gray eyes had become a brilliant blue. And then she saw that her strawberry blonde hair was lightening, lengthening, and gaining no small amount of wave. As she watched, she could also feel it behind her as it cascaded down her back. Within seconds, she was a platinum blonde with hair that grew down to her knees; since she was sitting down now, it reached the floor.
She'd been so fixated on her hair that she hadn't been noticing her face. As she looked back, she was startled to discover that she was almost unrecognizable to herself, with newly plumped-up lips, a smaller nose, higher cheekbones, a more rounded chin, and probably dozens of other changes that had transformed her from "cute" to "drop-dead gorgeous." Then a rainbow of colors faded onto her face, and within seconds, it looked like she was made up to appear in a porn movie, with everything from glossy red lips to multicolored eye shadow to ridiculously long, dark eyelashes.
Just as she felt a weird sensation in her mouth, like her tongue was wriggling without her commanding it, she felt a violent orgasm wrack her body. Liquid forcefully sprayed out of her pussy, mostly being absorbed by her hand and the panties that were being stretched over her newly sized body. Her first thought was that she'd peed, but then a sweet smell reached her nostrils. She lifted her damp hand up to verify that it was the liquid, and then took an experimental taste -- she was first surprised that her tongue extended from her mouth a lot further than it used to, and then she was surprised that the liquid was so delicious. She licked her hand clean trying to figure out what it tasted like. It seemed to be mostly vanilla, but there was some mint in there as well, and maybe some cinnamon.
She still felt like her pussy could use some attention, but she gritted her teeth and stood up. Between her stretched tank top and her magical breast enlargement, her nipples were very visible, and she grabbed a bath towel and wrapped it around her torso as best she could. She then picked up another bath towel and wrapped it around her midsection, primarily to cover up the giant wet spot she noticed on the front of her skirt.
As she stepped towards the bathroom door, she stopped and noticed that she was walking on tiptoes. Try as she might, she couldn't get her heels to go down and touch the floor. Strangely, it felt natural, although it looked weird with the white Keds she was wearing.
She shrugged, unlocked the bathroom door, and went out in the hall. She yelled down the stairs, "Okay, Mikey, what did you do to me?" Was that her voice? It sounded an octave lower and seductively throaty.
Mikey came to the bottom of the stairs, looked up at her, and said...
