A/N: Sorry for the late update! Life happens (sigh). Once again, this story takes place before the invasion of Soul Society. The entire story will be told in Matsumoto's POV, to avoid any confusion about who is talking from what body.

::Walk Two Moons::

Matsumoto took a few gulps of air, hands clutching her uniform, fighting panic. When she looked up, she saw that Gin had already rolled onto his side and was staring off into the depths of the ruined laboratory, seemingly unfazed by their situation. It took her another moment to realize that although he was facing the laboratory, he was looking at her.

When their eyes met, he looked away again and resumed staring into the debris, one slender arm supporting his weight, and the other resting casually across his supple waist, tucked tightly under his new bosom. Was he really not going to say anything? It looked as if he was waiting for her to calm down before he spoke, but if anything, she was getting more wound up by the second.

There was a moment of silence. Then –

"My boobies!" Matsumoto cried hysterically, clutching her flat chest and remembering the matter at hand. Lurching into a sitting position, she watched Gin do a rare double-take. His eyes, widened in shock, shifted from her, to the wall, and back again, like a little boy caught in an uncomfortable situation. "Give them back!"

"Rangiku-chan, these would look rather strange on my body," Gin replied, pushing himself up, one arm cupped protectively around his new assets.

Undeterred, Matsumoto crawled towards him on her hands and knees. "At least let me check to see if they're okay!" She pleaded, seizing his kimono. Gin yelped and caught her wrist as she tried to thrust her hand down the front of his uniform.

"Rangiku!" He spluttered, "what are you doing?"

"Don't be stingy," she cried, trying to maneuver her other hand towards her treasures. "They're mine, anyway!" Was Gin blushing?

A sudden crash made them both turn, startled. "Who's causing this detestable racket?" Mayuri emerged from the depths of his ruined laboratory, scowling. His eyes widened at the sight of Ichimaru Gin, uncharacteristically hysterical and tugging determinedly on Matsumoto Rangiku's cleavage. "What on earth is going on here?"

Matsumoto let go of Gin's assets with a final yank and turned to the captain, reluctantly opening her mouth to speak. Strange as the situation was, vice-captains were required by protocol to answer to all captains, regardless of their division. "Kurotsuchi-taichou," she began.

"Well?" The mad scientist demanded again, tapping his foot impatiently.

Matsumoto felt two cool fingers sliding quietly over her hand, and hesitated. When she peered at Gin out of the corner of her eye, he shook his head very slightly, auburn waves falling over his face as he did. Suddenly wary of the mad glint in Mayuri's eye, she checked herself. He likes using human subjects, a tiny voice whispered in her ear. If he found out they had been adversely affected by his chemicals, there was no way he'd hand them over to the Fourth to be checked out. He'd keep them in his lab and experiment on them until he found out exactly which of his chemicals did what to them. In the same instant, she realized that she was now in Gin's body, and Gin was a captain.

"Kurotsuchi-taichou ," she repeated, trying to think. "Don't you have somewhere else to be?"

The scientist raised a mocking eyebrow. "Oh? How convenient. Actually, I believe that I am just fine where I am, overseeing the repairs of my ruined laboratory." He spat the last three words as though they were poison.

"You have a hair appointment at five," Matsumoto said, somewhat lamely.

Gin pinched her.

The scientist remained where he was, staring at them suspiciously. "You don't sound like yourself, Ichimaru-taichou," he finally said, flatly. "Have you misplaced your personality, perhaps?" It was widely known throughout Soul Society that Mayuri loathed Gin because Gin often made snide remarks about him and didn't seem to take Mayuri and his research seriously. Gin actually didn't take anyone seriously, but Mayuri took it as a personal affront.

"Smile at him," Gin whispered.

Matsumoto gave Mayuri her best attempt at Gin's trademark leer, but the scientist was unswayed.

"Did the two of you sustain any injuries during the explosion?" He asked, peering at the two of them suspiciously. "Or come into contact with any of my chemicals?" A deranged look slowly came over his face. "Because if you have, you must inform me immediately. Extensive testing will have to be conducted in order to rectify any symptoms you might be experiencing, as well as to evaluate the nature of some of my more unstable chemicals…" He grew more visibly excited at each prospect.

"No!" Matsumoto exclaimed forcefully, genuinely frightened. "We are completely normal. Just look at us!" She and Gin turned to look at each other as Mayuri stared at them. She was still clutching the front of Gin's uniform in both of her fists, the two of them sitting on the ground of the walkway amidst strewn rubble from the explosion. "Completely normal…" She repeated weakly.

Mayuri stared.

"I don't talk like that," Gin whispered to her, looking amused.

Shut up! She mouthed at him, making a face. She wracked her brain frantically for something to say, before Gin's half-lidded eyes gave her an idea.

"Don't you know how to read the atmosphere, Kurotsuchi-taichou?" She slid her hands down to Gin's waist as she tried to imitate his lazy drawl. Gin covered one over her hands with his good-humoredly, although he didn't seem to know where she was going with this. "Rangiku and I are havin' some…private time, as you can see. Kindly leave us alone?" If there was one thing which disgusted Mayuri more than anything else, it was the idea of love and people having positive relationships with each other.

She snuck a peek at the captain, who was still standing over them, looking unconvinced. Swallowing an internal sigh, she raised one of her hands, threaded her fingers through Gin's long hair and pulled him in for a quick kiss. When she pulled away, secretly gratified that her lips (well, they technically belonged to Gin for now) were nice and soft, her friend looked so thunderstruck she had to choke down a giggle. She had been slightly worried about whether Gin would play along, but he just licked his lips unconsciously and stared at her. Unable to resist herself, she kissed him again. Just for the hell of it.

A strangled sound erupted above them and reminded Matsumoto of another presence. She winked up at Mayuri. "Care to see more?"

"Disgusting," the scientist snapped, before turning on his heel and stalking back into the ruins of his laboratory. "Don't think this is over, Ichimaru," he called nastily over his shoulder before he disappeared into the darkness.

Gin was staring at her, an odd look on his face. "I had no idea you kissed people so easily, Rangiku-chan," he remarked finally, his face inscrutable.

She turned to him. "Don't be so cold, Maru-chan! Was I a good kisser?"

Gin gazed at the sky. "I have no idea. I was too busy admiring the disgusted look on Kurotsuchi-taichou's face to notice."

Matsumoto giggled. "Come on, don't be stingy! You have to admit it was a good idea." She tapped her lips pensively with a finger as another thought suddenly occurred to her. "Maru-chan, was that the first time I've kissed you?"

He glanced at her quickly before his eyes drooped half-shut again. "That doesn't count."

She pouted a little.

They came to an agreement. To avoid discovery by Mayuri, they would keep the switch a secret.

"We should first try to find a solution ourselves," Gin advised as they hurried back to the division offices. He caught her arm as she tried to head into the Tenth Division office. "Not here – you're a little further down. If we can't find a solution within three weeks, then we consult the Fourth and brace ourselves for the consequences. Sounds good?"

"Sounds good," she agreed, and tried to kiss him again.

He ducked her. "Are you that in love with yourself?"

"I never knew my lips were so soft," she mused. "Also, Maru-chan, you make a funny face when I do it." Why hadn't she thought of kissing Gin earlier? It would be funnier to see the funny grimace on Gin's own normally unreadable features, rather than her own.

And even though when she looked, she saw her own face, the knowledge that it was Gin made her feel all warm and bubbly when she kissed him. She couldn't seem to stop herself.

Gin gave her a gentle swat on the head. "Run along," he chided. "Remember ta meet me in the training courtyard after lunch. We'll talk more later."

Chapter Three Preview:

"No need to be shy!" Matsumoto cried, yanking firmly on his uniform. "It's nothing I haven't seen before!"

I know this is a short update, but hope you guys enjoyed it! Body-switching is hard to write, so please let me know if there are any confusing parts that I need to improve on! I will try my best :)
