A.N.: I came up with this story a few days ago and I couldn't get it out of my head so I just decided to work on it for a while. A fair warning: this involves Rukia becoming very slutty so if that's not your interest, then hit the back button now.

The Pink Leotard
Chapter One: Rukia's New Outfit
Shortly after the end of the Winter War
Squad 12; R&D Dept.
"Thanks for coming to help," Nemu said as Rukia passed her another box.
Wiping the sweat from her brow, Rukia nodded and handed the homunculus lieutenant another box. "No problem, Nemu. Captain Ukitake insisted I helped you guys."
The pair were in the vaults, deep beneath the Soul Society. The newly promoted Rukia had been instructed to assist Nemu as she and the other members of Squad Twelve worked diligently to help make everything go back to normal. While some of the other lieutenants were working in other parts of the department, several others were in the World of the Living, making sure that the transition between the fake Karakura Town and the real one went smoothly. Right now Rukia was simply helping Nemu take boxes down to the vault. What they contained, Rukia didn't dare indulge her curiosity and open one. When it came to Mayuri Kurotsuchi, anything goes.
"Your assistance is most appreciated," Nemu smiled, having opened up a tiny bit to her fellow Soul Reapers in the past few months. "Master Mayuri was rather explicit that he wanted these sealed away promptly."
"If it's alright to ask…what are these?" Rukia said as she handed her the last box.
"They're containers. They're holding several of Master Mayuri's failed experiments."
"Do I even want to know?"
"No, you don't." Closing the door, Nemu hit a few keys on the keypad and smiled. "There. All-"
The pair were interrupted when the unexpected happened. Both girls looked around as the room suddenly started to shake. "Earthquake!" Rukia shouted.
"Stay calm!" Nemu said, the shaking making it hard to stand upright. "Master Mayuri designed this vault himself. He made it capable of withstanding earthquakes." However, she turned pale when the shaking worsened and the walls of the vault started to crack. "But Master Mayuri has been wrong before…"
Rukia stayed close to Nemu, her eyes on the ceiling to make sure they weren't buried alive. The shaking started to undo the locks to some of the safes, their doors being knocked off their hinges.
Just when the pair feared that they weren't going to make it, the shaking stopped. "Phew!" Rukia breathed, her heart pounding. "We're okay."
"This isn't good," Nemu muttered as she saw that many of the safes had been opened. "Master Mayuri will be displeased. I should get to work immediately to reseal these."
"I'll help."
"Wait here while I go get tools. I also need to check to make sure that the Seireitei wasn't damaged in the quake," Nemu told her. "If you see anything move, you should probably scream for help."
Rukia deadpanned as Nemu entered the elevator and went up. "Oh gee, leave me here with a bunch of Mayuri's experiments, why don't you?" Looking around, Rukia wondered what she could do. The doors to the safes were too big and heavy for her to lift on her own. She decided to inspect the opened ones to make sure that nothing slimy didn't crawl out and try to eat her.
As she made her way to the first one though, she noticed something odd. "Weird," she noted as she leaned down to see what was inside. Through the vault's dim lighting she saw a single item resting inside. "Why'd Mayuri put this in a vault?" Curiosity got the better of her and she reached for the item, careful to make sure that nothing bad was about to spring on her.
Rukia pulled out a pink leotard. It looked like something a gymnast would wear but it seemed rather skimpy, especially in the lower back area. "What the hell? Why'd Mayuri put this away?" She rubbed the fabric against her fingers and didn't sense anything nefarious. However, as she held it she could feel something strange about the item, making her wonder what it was exactly she was holding.
"I'm back."
Nemu walked over to the lieutenant, a box full of power tools in hand. "Well, you'll be pleased to hear that the Seireitei is relatively unharmed. There was a bit of damage to Squad Eleven's barracks but there haven't been any reported casualties."
"Thank goodness," Rukia breathed a sigh of relief. "Um…hey, Nemu? Want to tell me what the story with this is?" She held up the pink leotard. "Why'd Captain Kurotsuchi put this away?"
Taking it from her hands, Nemu examined it and did her best to recollect it from her time in archiving the vaults containers. "Oh yes, I remember now. This was supposed to be a combat raiment."
"A…combat raiment?"
"If the data logs are correct, it was supposed to enhance a Soul Reaper's attributes to peak efficiency. I can't really remember much details about it though. The reports were rather vague. What I do know is that this was the only prototype ever developed."
"Why'd it get archived then?"
"It was Kisuke Urahara who designed it. I believe Master Mayuri might have placed it here out of spite. From what I know, when he took over the department he did much to erase Kisuke's presence here, along with all of his developmental experiments he found no interest in." Nemu handed the leotard back to Nemu. "Would you like to keep it?"
"Keep it?" Rukia looked at the thin article of clothing with a worried face. "Won't Captain Kurotsuchi get angry if you give something from your vaults away?"
"Master Mayuri has already deemed the combat raiment irrelevant. It will not be missed. I am curious as to what its overall functions are. Why don't you test it whenever you're on patrol and report your findings back to me. I can tell Master Mayuri you're cooperating in a joint experiment if he finds out."
"I see…" Rukia looked at the piece of clothing and decided that it couldn't hurt. "Will it fit me?" She knew she was rather small but then again, so was the leotard.
"It conforms to the user's body. I believe that even Lieutenant Matsumoto could squeeze into that."
"If you say so." Rukia pocketed the leotard and decided to get back to the matter at hand. "Okay, should we get to work?"
"Let's," Nemu replied while pulling out a drill.
The next morning…
Squad Thirteen; Rukia's Quarters
Rukia was thankful that her promotion came with her own quarters. She would have to go back to the Kuchiki Manor every day in the old days. Now she could stay at Squad Thirteen and relax on her day off. She needed it too, having spent yesterday hefting heavy doors with Nemu. Ukitake had given her the day off, leaving Rukia to her own devices.
Dressed in a simple robe, Rukia stared at the leotard in her hands. All night, she couldn't get it out of her head. She wondered if it worked or if it was just some joke of Kisuke's. "Guess I won't know until I try it," she murmured.
Checking to make sure the door was locked, Rukia stepped out of her clothes and underwear, her nude body standing in the middle of the room. Holding the leotard open, she put her feet through the holes and brought it up her legs.
Rukia was right about one thing: the leotard was skimpy. The lower half felt like nothing but a tight thong, her ass almost completely exposed. Rukia blushed as she stepped in front of a mirror to admire herself. After a few seconds, nothing happened. "Geez, what was I thinking?" Rukia facepalmed. "Like this thing could actually-"
Her words dissolved in her mouth when the leotard started glowing. Rukia's head rolled back as sensation swarmed her body, the leotard working its magic. She felt a slight twinge of pain in her spine as the outfit engrained itself into her body, reshaping her from the inside out.
The first thing Rukia noticed was that she was growing taller. Then her breasts felt hot and soon they started to expand, stretching the fabric of the gymnast outfit to the limit. Her back arched as her ass started to grow as well, her cheeks becoming firm and rounder. She tried to move but her body was stuck in place as her body changed. Her hair grew longer and sprawled down her shoulders. The bones in her thighs creaked as they expanded, giving her thick, voluptuous thighs. Even her stomach was subject to change, her flat stomach hardening with smooth abs.
The glowing finally faded and Rukia wobbled on her changed legs before looking up to see what had been done to her. Her eyes widened, not recognizing the woman in the mirror. "Oh my goodness! So this is what she meant by increasing attributes!" she gasped as she took in her new, seductively beautiful body. The leotard around her was stretched to the limit, Rukia's DD-sized firm breasts peeking out the sides. The crotch of the outfit dug into Rukia's womanhood, her ass on full display in the back.
"Oh my god! That thing completely remade me!"
Rukia suddenly felt a wave of panic. What would her captain say about her new change? Or Renji? Or heaven forbid, Byakuya? "How do I change back?" she said hurriedly.
Knock, Knock!
"Lieutenant Kuchiki?' came the voice of Rukia's subordinate, Kiyone. "Are you in there?"
"J-Just a sec!" Rukia started to panic. 'This isn't good! If she sees me like this she'll tell the captain, who'll tell Captain Kurotsuchi! He'll be livid if he found out I took something from the vaults! And heaven help me if Brother finds out!'
As quickly as she could, Rukia scrambled to get out of the leotard. The item peeled off her skin, making the girl twinge in pain from having it disconnected from her spine. However, as it left her body, Rukia started to glow again and she shrank back down to her normal self. "Oh! It only works if you're wearing it," she realized before hearing Kiyone knock on the door again. "Just a second!" She quickly slipped on a robe as fast as she could and tossed the leotard to the side. Opening the door, Rukia gave a quick smile. "What's up?"
"Captain Ukitake has a new assignment for you."
Rukia sighed. "So much for a day off." She looked back up at Kiyone. "Okay. What is it?"
"We've gotten reports of several Hollows in the Rukon District. He'd like you to deal with them."
"Got it. I'll head out immediately," Rukia nodded.
Kiyone smiled and left, leaving Rukia to get ready. Closing the door to her room, Rukia looked again at the leotard on her bed. Walking back over to it, she picked it up and examined it. She didn't know why but she felt drawn to it, a sudden compulsion to wear it again to turn back into that seductive, voluptuous woman it made her. "I guess it couldn't hurt to see if it changes a person's combat abilities," she said, rationalizing the matter. Stripping out of her clothes again, Rukia put the leotard back on. That odd sensation of her body changing came back to her, swarming her head with emotion. As she turned back to her big-tittied self, she couldn't help but sigh lustfully as lewd thoughts entered her mind.
Staring at herself in the mirror, Rukia pushed aside those impure thoughts and decided to get on with her mission. "But first…I'm going to need a bigger uniform…"
