You follow the magical girl to an elevator. She presses the '14th floor' button.
'I bet you'll see all kinds of neat things working in the research division! I heard they made a ray emitter that can transform a hundred people at once! And those orgasm-powered energy generators... We all owe you scientists one for that!' — she says, shifting her weight from one leg to another, flexing in excitement.
Orgasm-powered generators?
The glass door of the elevator open and you go down a long hallway. You see cameras on walls, watching your every step.
After a series of glass doors and turns you finally arrive at the lab.
It looks like a big hall separated into many blocks by glass walls. Women in rubber costumes work at computers, run around with spreadsheets and operate all sorts of weird machines you've never seen before. You take a closer look at what is happening in one of the glass sections.
A young woman is tied to a steel pole! Her hands, neck, waist, knees and ankles are all attached to a large pillar with rubber straps. She can't move, just wiggle. On the other side of the room there is a tubular machine with wires and steel bars coming from inside the hull. On the end of this tube you see four robotic manipulators holding a big green crystal in place.
Suddenly, the machine starts visibly shaking. A beam of green light bursts forth from it, focusing through the crystal and then onto the tied girl, making her face twist with either pain or pleasure: you can't hear anything as the glass room is soundproof. After a couple of seconds the beam dies off. The girl, however, is still wriggling and screaming. Her skin becomes shiny. With every second passing, it becomes more and more evident that it's latex and that it's getting greener. You stand there, watching in awe. The magical girl seems just as interested, nearly bumping into the glass wall with her nose.
After a full minute the girl's skin finally becomes bright green latex. Even her lips, and eyes are green. She closes her eyes and they merge with her face! It's featureless now, just a plain rubber sphere. The girl's hair retracts into her head, and the head itself gets smaller, disappearing into her shoulders. The test subject's arms share the same fate, retracting into her torso. Her legs merge together into a latex tube.
A hole appears back where the girl's head used to be. It increases in size, removing the shoulders. Same thing happens down bottom: a hole appears where the victim's feet would be.
You finally start getting an idea of what she is turning into. It's a rubber dress!
The bottom part of the dress forms a layer of ruffles over it. Then another one. And another one! The layers pile on, making the bottom part huge like... a ball gown's. Finally, the process stops. Black frills appear at the top of the breast section and a rubber flower blooms in the middle. The ball gown is complete, ready to be worn.
As scientist come an unstrap the dress from the pole, carrying it away, your newfound friend asks you:
'Cool, huh? So... would you want to do something like this?'
'Like what?'
'Like becoming a dress'
Before you can answer, a tall, stern-looking woman comes over to you.
'Ah, there you are! You're late! Get to my office and I'll assign you to one of the projects. Make it quick!' — she says sharply, before shooting off to some other researcher.
The order enforcement girl shrugs.
'I guess I should be going now. Nice meeting you~' — she says, waving her hand and turning around.
'Hey, wait!' — you stop her. She looks back at you.
'What is your name?'
'Christy' — she smiles. 'I really gotta go. See ya!'
You sigh. She didn't even ask for your name. She looks kinda cute...
Time to get some work done. You follow the markers on the walls and find the project manager's office. What are you going to get assigned to?
