You Wreck Me

Summary: McKenna Lupin knew she was meant to be with her old brother's best friend, but he was always going on and on about that pesky Evans girl. She planned to break them up, not get involved with her brother's other best friend. Slightly AU.

Chapter One: Summertime and the livin's easy

"Rise and shine, sleepy head." The older brother of McKenna Lupin kicked the end of her bed. She groaned and rolled over. There was no possible way that he could be expecting her to wake up at this un-godly hour during her summer vacation.

"The Hogwarts train will be leaving soon." His voice taunted her. She knew it was a lie. While that would have scared her awake four years ago, now she was wise to his tricks. There was no way he was getting her out bed for some lame arse reason, like he wanted scrambled eggs and couldn't make them himself.

"Aw, let her sleep, Lupin. She looks so cute with the drool plastering her hair to her face like that." The familiar snickers caused her eyes to snap open wide. The infamous Sirius Black stood over the bed of little ole McKenna Lupin while she was in her night clothes. She immediately begin cover herself with the covers.

"Oh no you don't," Remus snatched the covers from her bed and through them on the ground leaving her in short shorts and a skimpy top. A blush covered her face as Remus and Sirius gawked at her.

"Kenna!" Remus exclaimed throwing the covers back on her, "Don't show my friends your…your…skin."

She scurried under the covers glancing up at Sirius, who was grinning from ear to ear. "How was I supposed to know you were bringing him my room at this hour?"

Remus ignored her comment and waltzed her closet. He pulled out the longest pair of jeans she had and a turtle neck sweater. He tossed them to her. "Here. Wear these."

"But it's summer." Kenna argued. She was only two years younger than Remus, but he treated her as if she was still a helpless five years old in need of his protection.

"So?" He was so hard headed when it came to her. McKenna didn't see how it was fair. The girls he dated were wearing low cut tee-shirts and short shorts barely covering their bum. She found him to be slightly hypocritical. The two boys looked at her expectantly.

"Are you going to watch me change?" Sirius smirked. While all of Remus's other friend shuddered in fear of Remus's wrath from looking at me, Sirius found it amusingly. He enjoyed hitting on McKenna to make Remus mad. "Only if I can help." Sirius made the comment at her, but watched Remus for his reaction. To his disappointment Remus only rolled his eyes.

"Of course you can, Sirius. I will especially need help the zipper on my jeans." While Sirius's comment went unnoticed, McKenna's comment sent fury to Remus's hazel eyes. The two of them fell out laughing. Remus stormed out not enjoying being the butt of their joke.

McKenna didn't hesitate to strip herself of the covers walking in her skimpy night gown to her closet to pick out her own clothes. McKenna raised an eyebrow at Sirius, "Do you mind?"

"Oh sorry," Sirius walked to her bedroom door and shut it, still remaining on the inside. McKenna rolled her eyes. While she loved using Sirius to make Remus mad she found his ego to be insufferable and undesirable.

"Very funny, but Remus is gone now so we can stop flirting." She continued to look through her closet trying desperately to ignore his smirk.

"Stop flirting? Why, I do not know the meaning of this."

Of course he didn't. McKenna was wise to the tactics and sexual antics of Sirius Black. After all, you'd have to be blind, deaf, and mute not to hear about the Marauders at Hogwarts. McKenna glanced over her shoulder to see Sirius pulling clothes out of her drawers.

"Hey!" She protested as he shoved a pink tee shirt and a longer pair of white shorts in her hands. She sighed figuring these clothes were as good as any she was going to find in her closet. "I'll be in the shower." She announced walking to her bedroom door and motioning for Sirius to exit as well.

"Ooo, mind if I join?" Sirius exited the room as requested, but Kenna didn't trust him so she shut her door after them to make sure it was clear he was not to go back in.

"Is it going to be like this all summer?" She and Remus's parents were almost always in another country during the summer doing work, leaving their home completely empty. Since both of their kids were excellent students and unusually responsible for their age, the Lupins allowed them to invite their friends over for break. Of course, that didn't stop them from acting a little childish every now and then.

Sirius smirked at McKenna getting uncomfortably close to her face. "Wouldn't want to break tradition, now would I?" With a sigh, McKenna ignored his last comment and made her way to the shower.

Her warm hand rubbed the steam off the foggy mirror, allowing McKenna Lupin to get a good look at her freshly out of the shower form. She brushed the knots through her long plain brown hair before squeezing a much of the water as she could out of it. She didn't really look anything like her brother. Remus was tall, had reddish hair and a skinnier face than she had while McKenna was shorter with longer light brown hair with a round face and piercing blue eyes. No one ever knew they were related until surnames were involved.

In fact they didn't really even communicate during their time at Hogwarts. It wasn't that they hated each other and it wasn't that they didn't get along. They just had a different group of friends and spent time doing different activities. But during the summer, it was like Hogwarts didn't even exist, and Remus and McKenna were back to being brother and sister.

McKenna loved the summer. She loved the weather, the swimming, and most importantly the lack of school work. In fact, she usually didn't start her homework until a week before the Hogwarts Express departed. McKenna dressed herself in the clothes Sirius Black had picked out for her. Remus's friends often spent the entire summer with them while McKenna's best friend only spent a week with them here and there. While she hated being the only girl with a group full of guys, but she understood Reagan's need to spend time with her own family.

When McKenna was finished dressing she opened the bathroom door and let all the steam rush out into the cold house. With a frustrated huff, she waltzed over to the thermostat and adjusted the air condition. Must those boys keep it so cold in here all the time? She did not enjoy layering her clothes on in her own home. She trudged down the back set of stairs that led straight into the kitchen.

The Lupin house was definitely no mansion, but it could certainly hold its own against most other houses. It had five bedrooms in all, one of which was a part time Library, even though Remus was probably the only one in the family who ever cracked open a book. There were three bathrooms, a formal dining room, a huge kitchen, and a breakfast nook. There was definitely enough space to get from annoying prats when the time came. When McKenna approached the final step she was surprised to see Sirius and Remus had cooked breakfast for her.

"Yum!" She exclaimed grabbing a plate from behind her brother. Remus was standing at the stove top scrambling eggs with a spatula while Sirius was walking around with a bag of shredded cheese throwing it on all the food.

"No cheese on my eggs," Kenna said as Remus scrapped them on to her plate, "I'm on a diet."

Sirius let out an overly dramatic gasp, "You will have cheese on your eggs and you will like it."

Before Kenna could protest Sirius dumped a pile of cheese on her eggs. "Sirius!" She exclaimed moving her plate away from him, "I'm allergic to dairy."

He reached around Remus and threw some more cheese on her plate, dropping more in the floor than anywhere else. "Liar! You drink a tall glass of chocolate milk with just about every meal."

McKenna glared at the boy in front of her. How had he noticed that? Instead of protesting anymore she grabbed a piece of toast (which Sirius had already piled cheese on) and a piece of sausage before making her way to the square breakfast table. She sat in front of a tall glass of chocolate milk.

"Curse him," She mumbled before taking a sip of the milk. It tasted so cold on her throat.

"Remus! It's bloody hot in here." Sirius headed towards the thermostat, "How do you work this?"

Kenna clenched her jaw. Her toes were just starting to thaw out. It was Sirius first day, hell it was his first hour, with them and she had already had enough of him. The boys joined her at the table, scarffing down half their meal before their arses even touched the chairs.

"So, Moony, you have to practice Quidditch with me this afternoon so we will be prepared when James and Peter arrive tomorrow." The moment James's name left the lips of Sirius Black; McKenna began choking on the sausage that was half way in her mouth.

"Attractive." Remus mumbled as he watched his sister spit the chewed up sausage into a napkin.

"Gee, Kenna," Sirius snickered, "I would have thought you would be good at mouthing a piece of sausage." His comment earned him a glare from both Lupin kids; not that he noticed. McKenna chose to ignore him. She had a bigger issue at hand.

"James is coming in tomorrow? With Peter?" She tried to act like it wasn't the biggest news of her day. James Potter was not only the nicest friend her brother had, he was the most attractive. McKenna could spend all day just looking at his smooth face, his honey eyes, and his brown hair that stuck out in the cutest way. She had to choke back the urge to sigh as she remembered the smell of his shampoo.

Last summer her and James had spent several hours discussing muggle music and listening to her record player, her parents had sent her. James knew almost as much as she did about the Beatles. She smiled remembering how he had danced around their living room singing to her.

"Wipe that dreamy look off your face," Remus hissed as soon as Sirius was back at the stove fixing his plate again, "James is off limits for you."

McKenna was two seconds from protesting but Black was back at his seat before the words could escape her lips. Damn, did Remus have to know every bloody thing? Well, she would just have to be sneakier with her glances. She dropped her fork on her plate loudly, making it clear she was not happy. Neither of the boys noticed.

"You didn't finish your eggs," Remus stuffed almost a whole piece of toast in his mouth. McKenna shrugged throwing her napkin on top of them. "You know, dieting in not healthy for your age, Kenna. Mum wouldn't like it." Of course, he would threaten to tell Mum. Just once she would like to have a brother that would be on her side for once. Instead of responding, she grabbed her plate and walked to the kitchen sink, dumping the components down the drain. It was clear this day was going to be spent far away from her brother and his idiotic friend.
