AN: A few notes, first. The timeline of this story does not take place in sophomore year like in the show. We're making them seniors for the sake of minor/Derek issues. However, the situations from S2 will be used in this story with my own ideas incorporated into some of them, as well as other situations for our little wolves to get themselves in trouble with. I know it's very Isaac/OC centric this chapter, but Derek will be equally as important to the story as it progresses more towards the hunting and training, and when the Argents are introduced, appearance of the Kanima, etc. Also, for now, I'm leaving it Rated T, although it may be subject to change to M (because I'm a perverted minded bastard). There will be fair warnings if it happens, but for now, it's Rated T. Hope you guys like it!

There were very few things that Lydia Martin couldn't do. Luckily for Beacon Hills High School, throwing a memorable party wasn't one of them. There was one for every season, every holiday, and random celebrations for BHHS victories, even for the Chess Club, though no one could ever quite remember to invite them.

After a particularly long, depressing fall semester in Beacon Hills with the increased "animal attack" tragedies, Lydia decided that nothing would welcome spring any better than a chaperon-free pool party hosted by yours truly.

"That is so cruel," Stiles said in awe as he peered over his sunglasses to watch two scantily clad girls playfully wrestling in the pool. Boyd and Scott nodded absently in agreement, mouth unable to form the right words at the sight of the same girls stepping out of the pool hand-in-hand, bodies wet and swimsuits tight.

With a huff, the three of them reclined back into their chairs until Lydia walked towards them, a tray of drinks in her hand.

"But not as cruel as that," Stiles added quickly. He scrambled to his feet to throw an arm over her bare shoulders. "Hey Lydia. Great party."

She eyed him carefully, lips pursed, and shrugged his arm off. "Of course it is." She held the drinks in front of her and offered a cup to each of them. "You guys aren't drinking enough."

"Only because I want to remember this sight for the rest of the week," Stiles replied, gesturing to her body. "As a matter of fact, I want to remember it for the rest of my life."

Scott choked on his drink and hid his snicker in the cup as he watched Lydia pet Stiles' cheek with a "You're so sweet" before giving a harder swat and turning on her heel into Jackson's arms.

"One of these days, she's going to wear that bikini in my room, just for me," Stiles sighed. Boyd laughed and pulled him down to a chair.

"You can always find someone that actually likes you."

"At this point, I might act on Erica's year old crush on me if it means I get to have a girl in a bikini in my room."

"Uhm, I don't think you have that privilege anymore." Boyd nodded to a corner where a group of boys gathered around who was presumably Erica.

"Definitely not a privilege anymore," Isaac chuckled, stepping beside them.

The other boys raised their cups in greeting, and he nodded his acknowledgment before sitting down next to Stiles. It had been a long morning; Derek had sent him on four hours worth of errands, probably to keep him away from this party. He had a knack for being a bit overprotective with Isaac, at least more than with the rest of the betas—perhaps because he had no one else to take care of him. Even Peter had taken a fond liking to Isaac and would at times baby him like a son.

It was nice, though, that feeling of being cared for, but in moments like this when Isaac wanted to be a normal teenager, Derek and Peter would act like the overbearing parents who didn't trust him to be in such situations, with alcohol, girls, and peer pressuring classmates. It was ridiculous, Isaac thought, that the rest of the pack could do normal things without an overreacting parent; he can practically hear Derek from five miles north asking, If the rest of the pack jumped off a cliff, would you do it too?, and it was all he could do to not groan in frustration.

"Drink?" Stiles offered, holding a bottle out for him. Isaac eyed it and wondered if the stench of alcohol would leave his system by the time he got home. Even if it hadn't, he could tell Derek that it was Stiles' fault, and without a fail, Derek would gladly take it as an opportunity to scare him.

"Sure." This is what being seventeen is supposed to feel like, mind you, eighteen by the end of next month. Careless fun, drinking, pool parties, friends, laughter, all of it. So he leaned back into his chair and enjoyed what the weather and view had to offer. Only a few minutes passed when their foursome welcomed another person.

"I hope you aren't drinking too much. Derek would hate to train a group of pups with a bad hangover tomorrow."

The boys looked up at the shadow over them and found a smiling Alexandria McCall taking a seat beside her brother. Isaac noticeably cleared his throat and straightened himself, unable to glance at her without making obvious just how much she caught his attention.

"A bit overdressed, aren't you, Alex?" Stiles asked with a sly grin.

"Says the boy wearing a tropical shirt straight out of his dad's closet," she mused. "That should be burned, by the way."

Ignoring her comment, Stiles reclined in his chair and sipped from his cup. "A California babe with little motive to walk around half-naked; that's a first."

"I don't know if I'm offended by the stereotype or flattered you think I'm a babe."

"Avoiding my question still, I see. Maybe you're just afraid people will mistake you for a boy," Stiles offered, his lopsided smile giving away his tease.

Alex rolled her eyes and pulled at the hem of her white shore crop top that exposed her midriff and the strings of a purple bikini top under. "Actually, I think this is enough skin baring for now." Isaac was almost tempted to voice his disagreement, but as she stretched her legs in front of her, he was distracted by how long and smooth they looked up till where her shorts stopped high on her thighs. He quickly down casted his gaze; funny, the grass suddenly became interesting.

Scott threw his arms around his sister and said, "That's what I like to hear. And let's keep it that way." A couple of guys walked passed them and visibly laid eyes on Alex, much to Scott's (and Isaac's) annoyance. "Although I have sweats and a towel we can turn into a burka if you'd like."

"Clearly the male population," Stiles started before a girl walked by them, biting her lips with eyes fixed on Alex, "—and apparently the female part of it too—disagrees with you, both of you. We live in a democracy so it's only fair you agree with the majority will." He had that cheeky smile that Beacon Hills had come to associate with Stiles, the one that tugged at his lips when he felt himself winning an argument.

"I might swim in a bit. Calm your horses," Alex laughed. "Why aren't you guys showing off those fantastic lacrosse figures?" She raised a perfectly shaped eyebrow at them. "I need something to look at while I tan."

"You do need to tan. I don't get how you came out as Casper the Friendly Ghost when you're every bit as Mexican as this one," Stiles said, pointing to Scott.

"Hey!" the McCall twins exclaimed.

"For your information, my fair complexion is something I beginning to like. And I don't think I'm going to take tanning advice from you, Stilinski." Alex exaggerated a sigh and threw her hands up. "Fine, sit here, with your shirts on, away from those group of girls over there who have been eyeing you guys since they got here." Alex bit the inside of her cheek and covered part of her face with her dark chestnut hair as the boys jumped to their feet and shed themselves of their shirts. She counted backwards in her head from five before they went running into that direction.

It was then that she noticed Isaac fiddling with his beer bottle, small smile on his face. She got up to sit next to him and leaned into his taut body. "And why didn't you go?" she asked him.

Isaac cocked his head to the side to look at her. "I like it better over here."

Alex didn't know why she blushed, maybe because Isaac was blushing first, but she pulled away from him and said, "Stacy hasn't stopped looking at you, you know."

"And?" He took a sip from his beer.

"You should talk to her. I told her last week I'd put in a good word for her," Alex said.

"Meh, not really interested," he said simply.

"Well, consider it, Lahey. She's a great catch." It got quiet and it seemed as though Alex was considering something. In the next minute, she stood up and kicked her sandals off. "I'm ready to swim!"

Some kind of holy spirit must have heard his earlier wishes and forbidden thoughts, because the next thing Isaac knows, Alex dragged her top over her head and tossed it to a startled Isaac, and then pushed her shorts down over her round bottom to toss in the same direction. Alex looked over her shoulder and smiled.

"Join me?" She tightened the strings of her bikini bottoms and dived into the pool.

Isaac paid little attention to anything else other than Alex being jumped by her friends in the pool. After a few minutes, she lifted herself to sit on the edge, and God, Isaac really did try hard to keep his eyes from drifting lower than her neck, but it was really fucking hard. He always found her to be gorgeous; the entire school did. There were days he would go to sleep thinking about her, and like any guy, he would wake up some mornings to those thoughts, and it made things a bit awkward for him to face her without stammering and blushing through a conversation. He had a feeling tonight those thoughts would come creeping into his mind again.

Well, shit. Isaac hoped he didn't linger too hard at what was clearly not her face because when he looked back up, he saw her smiling at him, waving and beckoning for him to come over.

He waited a minute for his nerves to calm, and then downed the last contents of his drink. When he looked back to see if Alex was waiting for him, to his surprise, there she was, still sitting and looking at him expectedly while kicking her feet in the water. Isaac released the breath he didn't know he was holding and moved to peel his shirt off. And if he had been paying attention, he would notice the smile on Alex's face when he walked towards her.

Except he didn't notice; he was consumed, instead, with the frightening realization that this girl would be the death of him.
