'Life Altering Changes.

AN: Hello, scotch here with another story! It's A/U obviously as it is about the first time Aaron and Emily meet. This was a challenge from a friend of mine, she said I couldn't write smut. So now I have to prove otherwise of course. It'll probably be a two shot. But I've got some ideas, so who knows… I might make it more. Chapter One is T-rated but chapter two will be M-rated. Enjoy!

Chapter one.

"Aaron, come on. That's the third time this week." Aaron Hotchner sighed into his phone; he knew how much his wife hated it when he worked late so he'd already prepared for this conversation.

"I know, honey. But this is an important job and I can't just skip out. I promise I'll make it up to you." He heard her huff and halfheartedly tried not to roll his eyes, even though she wouldn't even be able to see it. Haley had always made a problem of his job, despite the fact she'd known from the beginning about his future plans. Apparently his job wasn't exciting her as much anymore as it used to, because now it was only another reason for her to whine. He sighed again as he saw his boss approach him. "Listen, Hales, I've got to go. Don't wait up for me." He only got an wasn't planning on it in return, and he tried one more time. "I love you," but his dear wife had already hung up the phone.

"Hotchner," Carl Adler raised his authoritative-sounding voice, "I need you to do another check on the house; you can start with the garden."

"Yes, sir." Aaron turned around and made his way down the stairs, silently cursing these damned security jobs. It wasn't what he'd been trained to do, but when your name was Elizabeth Prentiss you could apparently get everyone you wanted for your security. He looked up when he took the last step, just in time to see the lovely lady right in front of him; engrossed in what seemed like a thousand page thick book. Unfortunately for him, his mind didn't register the fact that he should stop walking.

"Oh" the young woman said as she collided with the security agent.

Aaron eyed the girl and realized who he'd just bumped into. "I'm sorry, ma'am. I wasn't watching my step. Are you alright?" he apologized, his face professional as always.

"Yes, I'm fine." She smiled up at him, "I wasn't really paying attention either, sorry."

They fell silent and Aaron watched the girl closely; she was the exact opposite of everything that had attracted him in Haley and yet he thought she was a very beautiful woman. Different from his type, but he couldn't help but feel drawn to her.

"Emily Prentiss." The girl extended her hand and Aaron took it.

"Aaron Hotchner." He smiled, showing of his trademark dimples. 'What are you doing?' His mind screamed 'you're married.' He instinctively withdrew his hand and cleared his throat. "I'm here on a security job."

"Ah." Emily chuckled; "you work for my mother?" She looked at him with what seemed like a sympathetic smile.

"I do," Aaron felt a jolt go through his body, there was something about this girl's smile. "A lovely woman." Watch what you're saying, and to whom you're saying it.

But Emily just laughed. "Right." She looked at him, "Do you want to go for coffee or something?"

"I've still got work to do, actually." Regret spilled through his voice. 'Why are you feeling regret?' his mind screamed again 'you're married, stupid.'

"Well, I'll see you tonight then." Her voice was sweet as always "at least, I take it that your job is for the party?" She looked at him with adorably questioning eyes.

"Yes." Aaron watched as she smiled at him, "I'll see you tonight." He let her walk past him and watched her going up the stairs. 'Stop staring.' He shook his head and got to the garden. This was going to be a long night.

"Emily, darling," she cringed as the ambassador called for her, probably planning a meeting between her daughter and some uptight, rich boy she was supposed to like.

"Mother." She smiled tightly, how much she longed for tomorrow. When she would leave for Brown and get away from all this crap.

"This young man," her mother looked at the man beside her, "has been asking me about you all night, why don't you share a dance with him."

Emily looks at the widely grinning man and fakes a smile back; the douchebag didn't even have the nerve to ask her himself. None the less she took his outstretched hand and let him lead her to the dance floor.

He swirled her around but all Emily wanted was to stay in one place, having spotted the dark handsome Aaron Hotchner on the other side of the room. When she'd finally succeeded in her goal she kept glancing over the douchebag's shoulder at the security agent. "Save me," she mouthed at him when their eyes locked.

The handsome agent smiled. He pushed himself away from the wall he'd been leaning against and walked towards the lovely lady. 'Married' his mind sang, but Aaron didn't even register it anymore. He tapped on the douchebag's shoulder, his voice deep and professional when he said "I'm sorry, I'm afraid I'll have to speak with Miss Prentiss for a moment." He briefly wondered what had gotten in to him, but it only took the disappointed look on the douchebag's face and the relief on Emily's to make him forget all about his wonderings.

"Excuse me," Emily smiled politely at the man and quickly followed Aaron out of the huge ballroom.

As soon as they stood in the hallway she let out a laugh. "Thank you," she grinned at him, "You've just saved me from another horrendous set up caused by my always lovely mother."

Aaron chuckled; there was just something about this girl that made him smile a lot. "You're welcome."

They looked at each other and Emily smiled widely. "Come on," she said, walking away from the security agent. "We're going in search for the real alcohol."

"I don't drink during work hours" Aaron protested, but yet he followed her anyway.

"Oh right." Emily frowned, just realizing she'd forgotten he wasn't a guest, "Well, we'll search for," she arched one perfect eyebrow, "the real lemonade? "

Aaron chuckled. "I'm not really thirsty," he said and looked around the kitchen, fooling himself and pretending he was actually here to check if there wasn't any security threat.

"Have you danced at all this night, agent Hotchner?"

"Aaron," he corrected without thinking about it. 'Distant yourself.' He ignored the voice once again, acting as if he hadn't gone completely crazy. "No, I'm on a job."

"How boring." Emily extended her hand, "Dance with me?"

Aaron blushed; he honest to god blushed. What was going on?

"Come on," Emily begged, "no one can see you in here, agent. No one to tell you to do your job."

"There's no music." Aaron tried, but it was a weak objection. 'And how about you're working, and married?' He was startled when Emily suddenly grabbed his hand and pulled him along into the hallway.

"I've got music." She laughed, a sound that made warmth hit Aaron's body. She opened one of the many doors in the hallway and pulled him inside with her. Letting go of his hand, she walked to a docking station holding her iPod on the other side of the room.

Aaron looked around the room; it seemed like a pretty standard room but hidden beneath all the typical radiation were little personal touches, experiences from the past. He heard soft music starting to play and his mind wanted to spring on alert, but his body wouldn't obey. This had been his only objection, hadn't it? She got him music and took away his only resolve. But still he couldn't move and he just stayed frozen to his place.

"Do you think you're able to dance now, agent?" Emily chuckled and extended her hand one more time.

That was all it took, he was done. How could anyone say no to a girl like her, how could any man ignore a smile like hers? Aaron took the outstretched hand and followed Emily's swaying, his mind going blank. "I think I can," he whispered.

They slowly swayed around the room, listening to the music that played softly in the background. "Are you leaving?" Aaron suddenly asked, noticing the suitcases in the corner of the small room.

"Yes," Emily said, laying her head on the handsome agent's shoulder. "I'm leaving for Brown tomorrow morning."

Aaron just nodded, even though he knew she couldn't see it. Nothing more was said and he carefully, but without realization, started to stroke Emily's back. She raised her head and Aaron looked down in the most beautiful eyes he'd ever seen, at least that's how he felt that moment. It felt like forever when she brought her head up and Aaron felt like he was floating outside his body when he closed the last distance between them and brushes his rough lips against Emily's soft ones, they tasted sweet. He let his hands travel down to the curves of her hips and pressed her tighter against his broad chest. What started out as a slow kiss quickly evolved into Aaron running his tongue along Emily's lips and his hands entangling with her hair. He hears soft moans elicited from Emily's mouth and it sends vibrations all through his body. Not once does his mind speak up now.

Emily's small hands find its way to Aaron's chest and start roaming around, pushing his jacket of his shoulders. She briefly wonders what the hell she's doing but the amazing hands of one Aaron Hotchner completely empty her mind within seconds. Her fingers bump against a few buttons and with shaking hands she starts undoing them.

"Emily." Aaron sighs in her ear, but it is all he can come up with before he's completely gone. He's not as patient as his partner and hastily pulls her dress down her body, before hungrily crushing their lips back together. He feels great… no, he feels fantastic and he's planning on keeping it that way. He walks them back to the king sized bed in one corner, taking up most of the space in the room. He carefully lays her on the bed and covers her body with his. They share another mind-blowing kiss before he sits back to pull of his dress pants. When they're both left in only their underwear, things start to heat up even more; their kisses start to get more urgent and their needs more apparent. They both needed to get this show on the road.

Emily looks up at the object of her affection. "Well," she smiled slyly, "are you just going to stand there all night?"
