"Calm down, girl. You're going to break something!" Aomi chided.
"I can't believe this place was here the whole time and we didn't even notice!"
The girls had stumbled upon the thrift shop largely by accident. It was pretty much just around the block from Aomi's apartment, but the store's unmarked green door went unnoticed for the 4 months she'd lived there.
As Robin jumped into another room in the store, this one containing old electronics, Aomi brushed aside a lock of her brown hair and stepped into a room full of clothing. As she considered the possible articles of clothing that may be hidden in the room, a familiar tinge of excitement took over and she became suddenly aware of the tight lycra wrapping her body, clinging to her and framing her naked crotch. Aomi subconsciously squeezed her thighs together and got a grip of herself.
"Woah, look at all these clothes!" Robin entered the room suddenly, grabbing a bunch of shirts and skirts. "I wanna try all these on!"
"Knock yourself out, haha" Aomi breathed. As Robin brushed past her, Aomi let out a sigh of relief. See, under her T-shirt and denim shorts, Robin wore a simple cotton bra and pink boyshorts. Just like any other girl. But under Aomi's long-sleeved turtleneck and skinny jeans, was a microfiber catsuit about six sizes too small.
Aomi briefly considered going through the piles of clothings, to search for some magical leotard or enchanted catsuit, but decided it probably wasn't worth the effort. It's not like she'd find anything anyway. With Robin inside the changing room, Aomi pushed her glasses up the bridge of her nose and left the room, entering a dusty annex filled with old books.
There was a incomplete encyclopedia set, consisting only of the letters V and Z. Next to which was a textbook on virology. As Aomi scanned the room, a strange glint caught her eye. In the corner of the room, on a book shelf just like the rest, was a book that seemed to... shine?
Aomi stepped closer and found that there was indeed, a book which had a shiny black spine. Was it leatherbound or something? Curious, she reached out for the book and pulled it out; but as soon as she made contact with the book, Aomi became suddenly aware of how tight her catsuit was. Stretched taut across her skin and pulling against her crotch.
Shaking her head and focusing, Aomi pulled the book out of the shelf and found herself... confused. The book was black and seemed to shimmer... almost like... latex? It was about 2 inches thick, and appeared to be bound in black latex. the hard cover was completely devoid of markings and seemed to have been polished recently, despite being on the shelf for god knows how long.
Aomi opened the book's cover and found the first page blank. Turning the page, she found paragraphs of text written in a language she didn't seem to understand. She tried to read it but found her mind being clouded. As she read the symbols, she became increasingly conscious of the suit under her clothes, squeezing her, teasing her. Slipping ever so slightly between her lips. She felt herself begin to moisten between the legs.
'What the hell?' Aomi closed the book, and found herself immediately let down. She felt completely normal again. Aomi opened the book again, to a random page this time. This time, paragraphs were written in English. She'd seemed to have picked up in the middle of a story, where some warrior by the name of Sade was expressing internal conflict, trying to decide whether or not to accept some divine honor, and fussing about what armor to wear.
Aomi flipped the page again and found more deliberation about whether or not Sade should accept some armor that was her birthright or something.
She flipped back to the front and read the symbols again, feeling herself grow moist, imagining the catsuit's zipper disappearing, imagining that she had no choice but to wear the catsuit secretly under her clothes forever...
"There you are!" Robin tore Aomi back to reality, unaware that she had interrupted one of Aomi's deepest fantasy. "I'm good to go! What do you have there?"
"Oh... oh uh... s-some book."
"Cool! Are you getting it?"
"Uh... yeah!" Aomi forced a smile and followed as Robin bounded to the checkout.
