Groaning as she pushed herself back up, Christina's initial thoguht was that she must have had a dream. She'd been on the site pretty late at night, well after her roommate had gone to bed and wouldn't hear any anomalous sounds that resulted from browsing through various tales of transformation. This thought persisted until enough of the grogginess cleared for her to see what lay in front of her: a wooden crate, unmarked, with a lid that she wearily opened to find...
"Ohhhh."
She'd only tonight posted her first-ever chapter - but she'd spent plenty of time browsing the site beforehand. The Vials had long been her favorite - a simple premise, so straightforward, yet so rife with possibility. A structure on which you could hang just about any kind of tale, and that had, over many years, accumulated a staggering variety of branches. So many people had done so much with it... and now, the titular bottles sat before her, just begging to be opened.
There was a brief, frantic moment as she grabbed up the crate and hauled it over to the bathroom, closing and locking the door behind her for maximum privacy. Ohhh, she knew exactly what she was going to do, so long as an assumption proved correct. Quickly she set it on the counter and started pulling out racks... one after another, after another... after another... after another, way more than it should have been able to fit. The box was bigger on the inside, just as she'd always imagined. Perfect.
Only after setting out dozens of racks on the floor and counter did she have everything out, and with the same haste she set about carrying through with her plan. Through all those years of reading about Mary being turned into so many different things, she had always wondered about one potential story: what if Mary took every vial at once? She'd never seen such a premise play out, nor had she been able to think of a good way to write it out herself, but the opportunity to take the place of Mary... that was something she couldn't pass up.
One after another, she started pouring the vials into the bathtub after plugging it, slowly filling it up with pink liquid. Her mind ran through every possibility she'd considered over the years - would it make her a freak? A blob? A goddess? Nothing at all? Ohhhh, there were so many ways it could go! She was already getting aroused, and by the time she had emptied the last vial out into the now-full tub, she was dripping with anticipation. A fantasy she had never expected to live out, finally coming to life.
There was one more thing she wanted to do, something she never saw in the stories. Stripping down, removing her clothes and underwear, she resolved to take a dip in the stuff. It was magic - surely bathing in it would be as effective as drinking it. There was one last moment in which she silently offered up a goodbye and good riddance to her old life before grinning, closing her eyes, and stepping inside the tub of mixed potions, quickly sitting down and sinking completely under the concoction to let it do what it may to her.
