“Trixie counted her coins with a frustrated huff, marking down the total before measuring it up against the revenue of her last few shows. There was a clear and steady decline, which wasn’t good, at all. She sat back and pondered her predicament, worrying about what would happen if this tend continued… It was the longest and largest loss of money to date, even worse than when Twilight Sparkle and company had exposed her for lying, which was saying something. She chewed her pencil for several minutes, pondering what to do when out of the corner of her eye she caught sight of a book lying out in the open.
 
A quick glance told her all she needed to know, this was a very specific book she’d borrowed from Twilight some time ago, and the mere thought of using it made her blush. But then, what was she to do about her dry spell otherwise? Grimacing, she grabbed for it and picked back up where she left off, blushing furiously as an evening’s worth of several chapters left her with some very, very special spells the young mare was itching to try~ It took another round of fierce internal debate before she sighed softly, setting her book down before focusing on her chest. Her modest pair of perky, B cup breasts; part of the overall average figure she sported. Another Trixie who existed a long time ago might have jumped at the opportunity to be anything more than average, and it astounded her that this Trixie hadn’t gotten around to going that far, but now as she focused on her chest she sighed softly, and reminded herself that this was only an experiment to get over these financial troubles.  
Taking a tentative, and figurative, step forward, she began to focus, closing her eyes when her horn lit up, channeling the magic from her horn and down into her chest… She gasped softly when she felt the first tingle, her blush flaring up again once she felt them growing. They felt numb at first, but then a pleasant warmth started to wash over her the bigger they got. She couldn’t help but smile a little, growing them out larger… and larger… and larger still. Eventually, the sensations were too much for her to handle, and she couldn’t help but reach up to grope her own breasts, moaning loudly and opening her eyes. Trixie jumped when she saw how big they’d gotten, nearly falling out of her chair before standing up.
 
They had to be at least a firm H cup by this point! Such was the price she paid for not wearing any clothes… Still, all things considered, this may not be such a bad thing after all~ So she thought after another round of groping anyway, moaning out loud to herself; “Trixie, you’re a genius!_{” She’d have to thank Twilight next time she saw her, though for now the newly-enhanced mare picked her book right back up again, skimming through it to see if anymore fun changes could be made prior to her next show}”
