I don't own Twilight

Warning: Please don't act like you don't know. Seth Clearwater's a girl. But its not my usual MO. Just read it. You'll see. Oh and for the sake of the story the vampires and werewolves go to the same school.

///Jaketh\\\(1)

I was always flat chested, so changing wasn't never a problem. I was a double A on my best days...or worst considering they got bigger when I had my period. Leah was helpful, by telling the boys to leave her alone so she could change. Reverse Physiology is a wonderful thing. With them peeping on her I had time to pull a baggy sweater on. I couldn't help but be suspicious of the 'cold ones'. But even with his mind reading abilities, her premonitions, his brute strength, the other males ability to feel and change moods, none of them figured me out. It was the pretty one, who I never really understood, who figured me out. And as confusing as she was, her knowing my biggest secret helped me understand her better. I guess it all started when I purposely failed my science quiz. I could go back farther, and blame Jacob and Emmet's bromance for the whole thing, but that'd be stretching it.

Even though it's true.

"Why are you here?" I said as I walked into the Science class.

Rosalie stared up at me from a book. I expected her to glare at something, but instead she smiled. When I look back at it, maybe I should have just ran right then and there when she smiled, but when most people see pretty things, no matter how dangerous they are, they stop and stare for awhile.

There was a whooshing and suddenly I was somewhere else. A clearing of sorts.

"Did you carry me here?" I said astounded at her brashness.

"Yep." Rosalie said nonchalantly, then suddenly pulled my pants down and lifted my shirt up in something that seemed like one fluid motion.

"What...What are you doing?!" I said my face flushing as her hands made their way to my boxers.

She stopped then pushed me down. She began straddling me. "Is there anything you want to do?" she said in one of the most seductive voices I had ever heard.

"Aren't you with Emmet?" I managed to squeak out as her hands roamed up to my chest.

"Yep. I'm actually testing a theory." She said as her hands brushed over the bandages that I used to wrap my chest.

"Which is...?" I said thankful that she had sort of stopped.

Then suddenly she pulled down my boxers revealing the fact that I was indeed female. "How far I'd have to go before you revealed to me that you were a girl."

"I...uh..." I really badly wanted a way to explain it. But nothing but the truth came to mind. And I wasn't going to tell some vampire who kidnaped me the truth. "How did you know?" I asked hoping she would soon get off of me.

She seemed to notice and quickly crawled off letting me fix my clothes. "Well, I had my suspicions, but today was what really helped me figure it out. 1) I could tell you bombed your test on purpose. I don't think a boy would do that unless he was trying to impress his friends, and I don't think the La Push's would be impressed by that. But then, if you were trying to be a boy, you'd probably put stupid answers. 2) You let me carry you all the way out here. I was moving pretty fast, but you didn't complain. Plus you were really light. You look a bit bulkier with your clothes, but when carrying you, you can feel how skinny you are. And finally 3, you didn't react at all to my sexy act. I'm the sexiest chick in school...no most likely in the whole state, and you didn't even get a boner. Not that that's possible but still..."

I blinked at her. "Wow...you're a perverted super genius."

"Who you owe a favor."

"Are you going to black-mail me?" she must of seen the terror all over my face because she her face quickly changed.

"No, I just had our seats switched in Science. I suggested to the teacher it would be a good idea. Emmet is now sitting by Jacob, and you're sitting by me."

"...Why?"

"Oh...well..." she looked almost embarrassed. "Well a lot of people see me as a cold person. And I want to remain cold to them...but I want them to see that I can be nice. So they like me better. So I get more popular."

"Kind of vain aren't we?" I asked sarcastically.

"Yep. But you're gonna change that...Kind of. Your going to be my stupid adorable friend I'm nice to, which shows I'm nice."

I blinked at her.

"Well you're a nice person and people seem to get along with you. So hopefully by getting along with you will make people think I could get along with them. Of course I'm pretty so they'll leave me alone, but I just need to make them think this."

"And in exchange for this you'll help me with Scien-"

"You don't need help, you're just faking it. I can tell that you're smart."

"Fine. You won't tell people I'm a girl."

"Yep."

"Fine." I said closing my eyes getting ready to roll them, but the same whooshing sound was made, and I was quickly back at the school.

So I got ready for whatever was going to happen. But I wasn't really ready. At all.
