A/N: Okay, I realize the whole undercover situation wouldn't really happen the way I'm writing it, but I'm changing things for my plot.
Elliot stared at the files on his desk and sighed. He had tried asking Olivia out on a date and somehow it had turned into a group thing. He had been too casual. But that had been his plan, start off casual and go from there. That was assuming she would have even said yes, if he had asked her on a formal date. He highly doubted she had ever thought of him as dating material. The more he thought about it, the happier he was that Munch had invited himself and Fin along to dinner. He and Olivia were great friends, and they were great partners, why ruin a great thing. He returned to his paperwork with a smile, it was decided he was friends with Olivia, that was it.
"What's with the grin? If you're having so much with paperwork, you can do mine." Olivia said with a laugh, knocking her file onto the floor. "I'm dropping everything today." She sighed leaning over to pick up her mess.
Elliot couldn't help but notice that as she leaned over so did her shirt and he had a clear view of her cleavage and black bra. "Just friends." he reminded himself. She was going to have to start wearing turtle necks if this klutz stage stuck around. Realizing he was still staring, he jumped out of his seat. "I'm going to grab some coffee, want some?"
"Yeah sure." Olivia smiled. "Hopefully I won't spill that too."
"Hopefully." Elliot agreed for a completely different reason, he didn't want to think about that. He shook his head and quickly made his way to the coffee station.
"I love when she wears that shirt." Munch said with a grin.
"What are you talking about?"
The grin turned into a smirk. "You know exactly what I'm talking about."
"Have you ever heard of sexual harassment?"
"Ha."
"Hey listen up." Captin Cragen said stepping out his office. "Has anyone heard of a group called the Thornleys?"
"Yeah, I've read about them." Munch said. "One of those hooty tooty things. They have a compound up down that makes Trump look subtle. You need a special invite to join and a couple mil in the bank."
"And a love of travel." Cragen sighed. "We think it's a group of child sex tourists."
"So a bunch of rich guys who like to have sex with kids form a club?" Elliot said shaking his head. "What's the address? We'll go pick them up."
"Hold on." Cragen said putting up his hand. "We only have rumours, no solid evidence. We can't just go busting in there. We're going to have to work this one from the inside out."
"We're going under cover?" Fin asked.
"Stabler and Benson are."
"Me?" Olivia asked. "I thought CST were mostly men."
"Only married couples are allowed to join the group. I'm working on getting you two an invite. It should be here by morning."
"Well than it's good we're going out." Olivia smiled. "I need a guy to at least buy me dinner, before I'll marry him."
"What? I can't marry you."
Olivia frowned. "We're just pretending El, we don't have to actually get married."
"Yeah. I know that. I know."
"Are you sure you're okay? You've been acting weird all day."
"I'm fine." Elliot assured her. "What do we already have on the group Cap?"
Cragen placed a pile of folders on Elliot's desk. "That's everything we have on the Thornleys, as well as background on the two of you as a couple. I want you to read it and know it by morning. I won't have this investigation ruined because no one buys you guys as married."
"Sure thing." Olivia said grabbing on the files.
"Finish up here, and than go home and study." Cragen ordered. "I'll see you in the morning packed and ready to be a couple."
"Packed?" Elliot asked. "Where are we going."
"Well no one would buy you as happily married living in separate apartments. The compound has rooms for out of town members, you'll be staying there." Cragen said before walking back to his office.
Olivia placed the files in her bag and grabbed her jacket. "Come on." She said standing up. "I wasn't kidding, I need to be bought dinner before I get married. We can quiz each other."
"Ok." Elliot agreed. "Oh, and some husbandly advice, stop wearing that shirt around Munch." Olivia looked over her should at John, who just winked at her.
