Sam was dreaming that there were icicles shooting after him while he was riding a cake down a hill when he woke up.

"WHAT THE HELL? No, seriously. What the hell?! Sam, get...no, no! How even...an...Sam, get up. Now."

Sam groaned and groggily sat up, not opening his eyes. He vaguely noticed that his feet no longer hung off of the edge of the bed when he noticed something was...off about Dean's voice.

"You been sucking helium or something?" he mumbled absentmimdedly. A second passed before he realized that his voice, too, was higher than usual. He snapped his eyes open.

A girl was standing in his room wearing Dean's clothing (which already said too much, really...couldn't Dean at least warn him first?), with his brother nowhere to be seen.

"Uh...who are you?"

"I'M YOUR FRIGGIN' BROTHER, SAM, BUT I'M," the girl guestured to herself vaguely, "I'VE GOT BOOBS," she blurted out, sounding horrified. In addition to that, she was very pretty, with straight dark blonde hair in a jawline cut, and she appeared very fit.

Sam frowned. "...Dean? ...Dude, you're a girl."

"Go look in the mirror, Samantha."

The horror must have shown on Sam's face, because the girl- Dean? smirked. Sam got out of bed- his clothes were too loose, and his pants pooled at his ankles- and ran into the bathroom.

This must be a really, really weird dream, he thought. No way this is actually happening. This is weird, even for them.

A face stares of of the mirror that's...him, but...not quite. The jaw isn't quite as square, and there's no barely-there stubble on his chin. And his hair is quite a bit longer. Plus...well, as Dean so well articulated it, boobs.

And a smaller waist, and hips, and just...you know. Girl parts. Sam thought he was going to be sick. After he woke up.

"I don't have any girl clothes," Dean hissed from behind him.

Sam started and turned to the voice.

And nearly felo over, because suddenly his center of balance was much lower than he was used to. Sam would guess he'd lost five or six inches of height.

Dean, meanwhile, was checking himself out in the mirror.

"I'm a pretty hot chick," he said, raising his eyebrows. "Glad my handsome face is still intact. No insanely hot scruff, but I'd say I more than made up for it, whaddya think, Sammy?"

"When you're done, maybe you should consider the fact that we no longer can pose as the FBI agents we did yesterday for the case we're currently working. Plus, we don't have any girl clothes, like you said. We need to buy some. But we don't have any credit cards with these faces." He paused. "That sounded really weird."

Dean thought about it, and then snapped his fingers. "Jo and Ellen," he said triumphantly.

Sam tightened his jaw slightly, remembering his last encounter with the pair, but he nodded. "Good idea. It's about seven hours away, we can leave in half an hour. That is, if you can manage to take a shower in that amount of time."

"I like to be clean, Sammy," Dean said, smirking.

"It takes less than forty-five minutes to 'get clean,' Dean. I never have hot water when you go first," Sam grumbled.

Dean pretended not to listen. "Whatever. It's my turn today, so it sucks to suck. You can wear some of my stuff- you're about 5'11" now, so it shouldn't fit that bad..."

"Dean, what about you? You're like five foot eight. Nothing we own is going to fit you."

Dean smirked. "Guess I'll just have to show off this rockin' bod to the world, then," he joked.

Sam rolled his eyes. "Get in the shower. And don't use up all the hot water!"

Ten minutes later- Hey Sam, can I borrow your conditioner? Friggin knots in my hair and it only goes to my- crap- my chin-

"Yeah," Sam called back, almost choking in his effort not to laugh. His own hair ended just underneath his chest, falling in loose brown waves.

Several minutes later, Dean exited the bathroom wearing his shirt, which now went down almost to his knees. Scowling, he gestured for Sam to go take a shower, which he did.

When he finished, he entered the room to find Dean wearing a bright pink bra and boxers. He turned away. "Should I...go brush my teeth again?"

"Please, your breath stinks," Dean quipped. "And if you're wondering about the bra, I found it in my bag. Cute brunette a week ago." He whistled. "Anyway, lucky find, right?"

"Toss me some of your- clean- stuff," Sam said, ignoring the comment.

Dean threw over a faded black (well, it was really more like grey now) AC/DC T-shirt, a blue-and-gray plaid flannel, and a pair of jeans.

"Thanks. I'll be out im a sec."

Sam pulled on the T-shirt, feeling self-consious as it fit rather tightly across his chest, clearly displaying his lack of a bra. He compensated by buttoning the flannel. Nobody could tell now.

The jeans were the tricky part. They were too tight at the top, too long, and weirdly cut. But they were better than nothing, so Sam wore them.

When he exited, he found Dean wearing a blue shirt that was tied at his waist with a rubber band, accentuating it's narrowness and allowing a strip of midriff to show. The jeans he was wearing were insanely long on him, dragging on the ground as he walked.

"My shoes are too big," he said, pouting.

"I can wear yours," Sam smirked.

Dean gave Sam the finger, and then slipped into running shoes. "Get in the car, bitch. We're going shopping."

Sam stared t Dean, stunned. "Did...you just quote Mean Girls?"

"When in Rome..."

-:-

Dean cussed out three other drivers on the way to the mall, even though Sam told him that, technically it was his fault because he kept overcompensating and hitting the gas too hard to accelerate.

When they finally arrived, Dean paled. "I have no idea what to do," he said, glancing around."

"We'll split up. You'll do fine. Go look for some decent pants. I'm going to try and find Victoria's Secret," Sam told him. Dean didn't look convinced.

"I'll meet you in J Crew in two hours. I expect you to be completely changed, understand?"

Dean nodded mutely.

Sam rolled his eyes and headed off, thinking of a cover story in case he had to. Name: Samantha. Easy. Story: maybe something about being in a hotel room and your brother stole all your clothes so you had to wear his? It was feeble, but Sam didn't think anyone would really pry.

He found Victoria's Secret pretty easily. It was neon pink and had posters of lingere models, after all. Feeling slightly awkward, he stepped inside.

There was a lot of underwear.

Sam grabbed the first bra he found and ducked into the changing room. Too big. He pulled another one. Too small? He guessed?

Finally, he found one that fit. In the chanfing room, he put it on under the AC/DC tee. Not bothering to pay (the current credit card in his waller said Richard Wallace Davis, so that would have been interesting), he strolled out.

Next, he found an ATM and got several hundred dollars in cash, so he wouldn't have to use credit for the rest of his purchases.

In Gap, Sam found jeans that fit perfectly, and a white tank top that he could wear under a plaid buttondown. There.

He checked his watch. Just over an hour. He still had fifty minutes to find Dean. Bras were really uncomfortable, Sam noticed. Or maybe he just wasn't used to them.

He was washing his hands in the bathroom when suddenly the lights started to flicker. Never a good sign.

Then the door locked. Sam tried to kick it down, but found that he no longer had the sheer body weight and muscle mass necessary. And now his foot hurt.

There was a hissing sound, and Sam frantically banged on the door. It seemed as though he was being ignored, or couldn't be heard, however. As the gas started to have an effect, he felt his muscles start to go slack. Dark spots clouded his vision, and he sat down on the floor. His last thought before he fell unconscious was that at least nobody would recognize him.

A/N 2: Well, what did you think of the first chapter? I really hope some people out there liked it...hey, how about a review? Do it for Dean quoting Mean Girls? Thanks for reading. Have a great day!

(as I said before, this story was for a prompt. If you have any story requests, pm me or leave a review with details and I'll do what I can!)
