She had kind of expected it to be warm, almost burning, and kind of tingly too. That was how she always imagined it - this sort of fire as your whole body got magically rewritten into some other form. This wasn't like that, not on that front at least; it was chilly, like a cool ocean she was dipping into in the middle of summer, submerging herself completely inside of. Christina couldn't help but giggle as she pressed her legs together, briefly imagining all those mermaid transformations she had fantastized and written in her head, but never really worked up the nerve to put to paper - or rather, to text document - and post up on the site.
One thing did match her fantasies, at least, and that was one of the good things. It was absolutely the most pleasant caress she'd ever experienced. Her whole body felt like it was draped in liquid velvet from head to toe, a soft, creamy massage evenly distributed across her skin. Some areas felt it more than others, of course, and her body shuddered the longer she spent with the liquid pressing into her most sensitive regions. It really seemed to like those places, judging by how much of the stuff she could blindly feel shifting over towards her butt, her breats, her folds.
It started to feel like her pores were opening up, and this was an opportunity the pink mixture took immediate advantage of. Moans left her mouth as she started to feel the transformative goop sinking into her skin, finding ingress wherever possible. Every pore seemed to become a vacuum, sucking in the stuff at a quickening pace - in mere moments, the level of liquid began to drop, and within about a minute, the entire pool full of liquid had absorbed itself into Christina, diffusing throughout her body. She grinned and grabbed a breast in each hand as she laid there, eyes shut tight and waiting for the effects to kick in... And waited... And waited...
And after about five minutes, her grin had turned into a frown. That... that was it? She looked down in confusion, expecting that at least her boobs might be bigger, but... nope. Nothing. She was still boring, normal, everyday Christina. Still just another random girl with a transformation fetish - and as she glanced up at the counter to see that the crate and vials were gone, she had to wonder if it had just been a dream. "Goddamnit," she muttered. Had she been too ambitious? Tried to soar too high. "Should have just found a big tits potion or so-"
The muttering was cut off by a screech as her chest surged with pleasure, as if the entirety of the flesh was being stimulated at once. Her eyes got wide as her rather average endowments suddenly swelled up, in seconds transitioning from 'okayish' to 'holy jesus'. They were so massive that she was momentarily locked in place, their flesh squeezing against the bathtub walls and keeping her stuck. She groaned, wishing at the back of her mind that they could be a bit smaller - and right on cue, they shrunk down, still absolutely enormous yet small enough she could move around once more. An eyebrow quirked as she tried to push herself up, her back straining - and after thinking super-strength would made this easier, she suddenly surged forward, muscles now rippling with power to make carrying the weight easy as pie.
"...OH MY GOD YES!"
She wasn't sure a better outcome was physically possible. She was a shapeshifter! All the liquid, all that stuff pouring into her body, it had made her physical form so malleable that she could alter it with a thought! The girl grinned as she stepped over to a mirror, bringing her chest down to a more manageable size before concentrating on a little variation to her hips. She spent a good minute or two fine-tuning the look of her butt and thighs, giving herself the absolute perfect hourglass figure, along with slapping an extra bit of height on for good measure. And, of course, some longer hair, long flowing locks of... blonde, she definitely felt like trying platinum blonde out for a while.
Just thinking about the possibilities made her head spin. If she was right, then absolutely nothing was limiting what she could do with herself, to herself - anything, from the classics like centaurs and mermaids and futas, all the way out to weird shit like that stuff with people growing tails out of obscure body parts that sexually violated them - fucking hell, if she wanted to, she could even become the physical embodiment of those songs that the one troll sometimes came in and posted. Hell, she might not even be limited to changing herself - the urge to go sneak in and see if her roommate could be altered by her own whims and hands was a powerful one. Or maybe she could just melt down, enjoy life as a completely formless existence for a bit, bask in the pleasure of not even being close to human for a little while.
The various ideas runing through her head were starting to get her soaking downstairs, and at her nipples too... and she practically swooned on seeing that the stuff coming out of her was the same pink liquid she'd been immersed in. "Oh my god," she muttered lustfully to her own reflection, utterly lost as she conceived of a billion new fetishes to make into a reality.
