You spend a while staring at the girl in the mirror, disbelief showing in her heavily lined eyes, pouty jet black lips hanging open on her incredibly youthful face. You shake your head a little, and sure enough she shakes hers. Eventually you let your gaze drop down to see the long black polished nails on your alabaster white hands as you grip the sides of the sink, and down a little further to see a pair of pert perky breasts heaving as you start to hyperventilate.
You don't quite let out a scream as you run back to the foyer, acutely aware of the ways your new body's assets bounce from the motion, but you call enough attention to yourself to draw some chuckles and cat calls from the other recovering party-goers. Eventually you find the woman in red from the night before, grab her by the arm and begin asking a dozen frantic questions.
"Ah!" she says. "You must that new initiate everyone was talking about last night. We haven't actually met." She glances around the room before shouting, "Hey! Who was I last night?"
A few shrugs later, someone points you to a door, leading outside to a swimming pool surrounded by white marble statues. Lounging in a nearby chair soaking up the sun is a woman with intimidatingly fierce features and wiry muscles, nude but covered in such an elaborate pattern of stripy tattoos you barely notice, as her hypnotically piercing eyes take you in, half her face falling into the shadow of the mohawk cresting a good foot and a half over her head.
The red woman shoves you towards her before dashing off without a word. Before you can stammer out another question, the sunbather starts to speak.
"From the look on your face, I see the explanation I gave last night was lost on you. Ours is a society of magic... and with the decadence that brings, we all get quite bored. Some become tricksters, like the owner of that little shop I saved you from. Some get up to dangerous self-experimentation. Most of us attend these little get togethers now and then to shed our flesh and try something new now and then. The wearer of your old form ran off before dawn with it if I'm not mistaken, rare as it is to bring in something new and unaltered... and male at that. You'll find men few and far between here."
As you start to object to your body being stolen she flashes you a big toothy grin. "Keep coming to the parties every week and you'll have it back eventually I'm sure, likely with a few improvements. Or you're welcome to take that new one home... I think most of us find the goth look passe, but from what I recall, that fetching little thing you are now is ageless, immortal, and extra sensitive... I'd be happy to demonstrate, but this body is strictly into men... come to think, yours may have been to besides."
That thought strikes you as rather chilling, although the sudden breeze hitting your naked teenage body can't be helping. Processing things as best you can, you ask just what you're supposed to do until next week.
"Whatever it is you like! I'm sure someone can conjure some spending money on your way out if you wish to return to the mundane world, or you can hunt down the owner of this manse... large enough I'm sure they have room to take in an apprentice, or at least a saucy little maid. Black and white are certainly your colors. I'd have taken you under my wing last night, but again, you do absolutely nothing for me like this... and I'm feeling so very... primal. Really, this conversation bores me."
Before you can ask any further questions, she stands, stretches, and leaps into the air, soaring over the roof of the multistory mansion bound for who knows where.
