My Sister's Best Friend

Introduction

My twin sister and I were best friends for our entire life. We did everything together. You hear many stories of how siblings hate each other and get into fights...not us. We told each other our biggest secrets, stuck up for each other, and most of all, we were always there for each other. I thought nothing would ever change our sister bond...until middle school rolled around...
You see...my sister Lily was never into boys or boy talk or anything like that.
Whenever I would tell her about a crush I had back in elementary, she would shrug her shoulders and change the subject. I never thought anything of it...until on the second day of sixth grade when I caught her fingers laced with another girl. I was confused...why didn't she tell me she liked girls?
She later told me she thought I would judge her...but she knows I would never judge her for anything she did...and I was still hurt she didn't say anything to me sooner. Soon, everything drastically changed in our lives. My sister was starting to date girls and hang out with all of the popular jock boys...meanwhile my only friend remained to be my sister. She would invite all these guys to my house and completely ignore my existence. I would sob myself to sleep every night...hoping that things would change...
In eighth grade Lily dissed most of her jock friends except one...Dax Winston. Sure he was hot and unbelievable fit...but he was a complete asshole. I saw him with a new girl almost every other day...and my sister would tell me about him having sex with them and then leaving them. I was disgusted by him, not to mention he was a dick to me. Everytime he would come over, he would push me around and call me all these horrible names...while my sister would just watch and laugh. Over time though...things changed.
Freshman year of high school I had finally started to...change...I went from a dorky little girl to a teenager with curves. Many people took notice and even a few guys would hit on me...but I ignored it and continued on with my life. But Dax...well he's a different story...he thought he could get me by flirting with me and backing me up into walls...but that only works in movies...and I was NEVER going to let Dax Gregory Winston play me. I was smarter than he thought...and I knew I would never fall for a dumb jock like that...or so I thought...
