It had been in the lipstick. Something the company had added to their recent batches. Perhaps it was in the blush, too - or maybe in the eyeliner. Fuck, maybe it was in the whole cursed lot of it - she couldn't know. All she knew was that, once she put on that first, fateful coat of glistening, tingling red lipstick, watching herself in the mirror as it clung to her lips, soaking into them, and puffing them up in front of her very eyes...
She needed more.
It had been a sample, and so there wasn't much at all for her to try, just a few days' worth. At first, she had watched, amazed as the red gloss had plumped up her lips, enjoying the sensitive tingles it brought her mouth as she had watched them grow in the mirror. It had to be the best damp lip plumper she'd ever seen and then some, she had thought - and the sensation! It was all she could do to stop herself from putting on a third coat, especially after moving that tiny stick around her mouth a second time, feeling the fresh wave of tingling, warm little waves as her mouth once again puffed up beneath the glossy coating.

It looked good, she had to admit, and felt amazing - but she couldn't work out why she struggled to resist it so much, why she yearned to apply more all the time, until she had wiped the very last vestiges of it from the bottom of the tiny, single-use applicator.
She had had a long night that night, barely sleeping, her huge mouth so big that keeping fluids in had become quite the challenge. It hadn't stopped tingling, only growing more intense as the hours dragged by, and she had been ashamed to admit that the feeling had eventually translated into an arousal that had driven her to a heated, needy, squirming, gushing mess in her bed, as she lay there, gently touching her gleaming, engorged lips, feeling the waves of warm electricity that emanated from even the tiniest touch. She wasn't one to squirt, but the wetness that had emanated from her body that night had been... Well, there had to be
