~Allison, I Know Your Sister Turns Everyone On, But You're The One I Want~

This is for @ForeverTB who asked for one where Allison starts falling for Scott but Scott's already dating Allison's sister.

Allison groaned as the doorbell rang once again. It was Saturday. Who was up as the ungodly hour of noon on a Saturday? She rushed downstairs, still in her pajamas, (which was basically just a messy bun, some sweats, and a tank top.) and opened the door. She was surprised to see her sister's boyfriend. Her sister was only a year older then her and Scott was Allison's age. Allison groaned at the fact that he saw her like this and turned towards the stairs.

"ASHLEY! SCOTT'S HERE!" She screamed. Scott winced and she only felt a small amount of sympathy. But then again, she was woken from her sleep on a Saturday when Ashley could have gotten the door. Ashley came bouncing down the stairs, her dark brown curls bouncing with her, and rushed into Scott's arm's. Allison sighed and walked back upstairs. She wasn't about to let this small delay ruin her Saturday. She still had about 10 hours of sleep to catch up on.

When Allison had finally woken up, she headded straight downstairs for a very late breakfast. Her mom had just finished dinner so that would have to do instead. She sat down at the table and almost screamed. Scott was sitting there too.

"Mom, Scott's staying for dinner tonight, if that's alright." Ashley stated. Her mom smiled.

"Of course he can stay for dinner." She said as she set a bowl of mashed potatoes down on the table. "Allison, why don't you set the table?" Her mom asked. Allison knew she was telling her to set the table though, even if it was stated like a question. Allison gave a fake smile and nodded.

She wasn't upset or anything. Okay that was a lie. Her sister and Scott had been dating for a year now and it was all okay at first because she hadn't liked Scott. Then Scott was around the house, like, 24/7 and she never got a break. He was always so sweet. He helped her mom with dinner, set the table, did the dishes, helped her mom make desert. He was always chivalrous and always there.

Allison had just gotten home from school, she had to stay after to tutor some kid in math. The kid wasn't that bad at it, he just had a hard time learning it at first. She walked into the living room and was about to collapse on the couch but there was Scott in her favorite spot.

"Scott?" She asked. He looked up at her and smiled.

"Hey Allison, Ashley just went to the bathroom. We're watching movies, want to join?" He asked. Allison shook her head.

"No, I actually have a lot of homework to finish." Allison lied. Scott nodded in understanding.

And that was only the first of many times that Scott was just randomly at their house. Allison started to admire his personality, then his features, then just him in general. And by the time she had caught on to what was happening, it was already too late.

She had a crush on her sister's boyfriend. She had no idea what to to about it either. What were you supposed to do when your heart literally broke every time you saw the guy because he was with your sister and would never like you? But maybe that would change soon. Allison and Scott were juniors and her sister was a senior with big plans to go to college out of state.

She finished setting the table with a sigh. Her sister looked at her oddly.

"You okay today Allison? You seem to have your head in the clouds. Anything on your mind?" Ashley asked. Allison had to stop herself before she said your boyfriend.

"No, not really." She lied as she sat down again. Her sister gave her a knowing look that Allison didn't really know how to feel about.

"If you ever need to talk you can come to me." Ashley smiled. Allison nodded.

"I know Ashley." Allison smiled.

A few weeks later Allison finally realized what the look Ashley had given her meant. She had just walked through the door when she heard screaming. Her parents weren't home so it must have been Ashley and Scott.

"SCOTT, I HAVE DREAMS, I WANT TO GO TO COLLEGE IN ARIZONA, I WANT TO GO TO ITALY, PARIS, ENGLAND! YOU HAVE TO FINISH YOUR HIGHSCHOOL CARRIER, YOU'D ONLY BE DRAGGING ME DOWN!" Ashley screamed.

"WE COULD MAKE THIS WORK. I COULD FINISH HIGHSCHOOL IN ARIZONA WITH YOU!" Scott screamed back.

"SCOTT, I ALREADY TOLD YOU WE WERE OVER, I DON'T WANT TO BE DATING SOME KID ANYWAY!" Ashley yelled.

"SOME KID?! SOME KID?!" Scott laughed bitterly. "I'M ONLY A YEAR YOUNGER THEN YOU ASHLEY!"

"EXACTLY! I SHOULD BE DATING SOMEONE MY OWN AGE!" Ashley countered.

"YOU KNOW WHAT?! I DON'T CARE ANYMORE, I ONLY DATED YOU TO GET CLOSER TO ALLISON! GO TO ARIZONA, SEE IF I CARE!" Allison heard a door slam but didn't have enough time to hide herself. She was in shock. Scott had only dated Ashley to get closer to her? That meant Scott had liked her all along! Scott stormed into the room and looked surprised to see her. "Allison." He said breathlessly.

"Was that true?" She asked. Scott looked confused. "The part about you only dating Ashley to get closer to me?" She clarified. Scott gave a sheepish smile.

"Uhh, yeah actually." Scott said as he rubbed the back of his neck in embarrassment. Ashley stormed out a second later and smirked.

"Now's your chance Scott. You said you only dated me to get closer to Alli', go on, get closer." Ashley said as she grabbed her key's and stormed out the front door and slammed it shut after her. Allison looked back at Scott with a cautious smile.

"Want to go on a date with me?" Scott asked softly. Allison laughed.

"Of course."

6 YEARS LATER

Allison smiled up at Scott.

"I do." She said confidently. Scott smiled back at her.

"And Scott, do you take Allison to be your wife?" The priest asked. Scott looked over at Ashley who was standing at the front of the line of bridesmaid's behind Allison. She was crying but she had the brightest smile on her face. Scott smiled wider as he looked back at Allison.

"I do." He said confidently. Ashley smiled. She was glad he had gotten with Allison.

"Then I now pronounce you husband and wife." The priest smiled. "You may kiss the bride." Scott pulled Allison into a kiss and the whole entire church erupted in cheers and cat calls (mostly from Stiles). When they pulled away Scott was grinning and Allison was smiling and crying. Scott smirked and grabbed Allison and lifted her bridal style and ran down the aisle with her giggling the whole way. Ashley watched fondly as she walked over to her husband of three year's, Derek Hale.
