Figured it was time to finally update this story when I had the time, hope it's been worth the wait.

Chapter 19

"For fucks sake!" he snapped throwing his bag into the back of the jeep as he glared down at his phone.

When he had woke up that morning Olivia was already up and out the house. She had left him a note saying they needed to move to the next step and he needed to make Mark believe he was having an affair. He had hoped to talk to her before he left for work about what had happened the night before. Things were moving fast between them despite the situation they were in. But he knew they needed to close this case before they could explore things further.

He had been waiting all morning for Mark to be in earshot so he could put the plan into action, finally heading out to lunch he had his chance.

"Everything okay there Elliot?" Mark asked from behind him. Elliot smirked a little to himself before turning around and sighing.

"Women problems, what else is there?"

"Trouble in paradise? I couldn't help but notice a little tension between you and Olivia the other night."

"That obvious huh?" he asked him sitting on the back of the jeep. "I thought moving here would help us you know, but no matter where we go, she always thinks I am going to cheat on her. I mean it didn't bother her when she was the one I was cheating with," he shook his head and sighed. "I don't know man it's all fun and games until they finally get their claws into you, then bang! As soon as the ring is in the finger everything stops, well apart from the bitching and accusations."

Mark stood with his arms folded as he listened to Elliot a frown on his face.

"God, first it's I didn't like the way she looked at you. Next thing you know sex is off the menu because a waitress smiles at you when she gives you the bill. Then it dries up all together. No matter how many times I tell her she is the only one for me, she just gives me a look."

"Well in Olivia's defence you were getting quite close to that woman at your party the other."

"That was to try and make her a little jealous, thought it had worked at first as well, but no just I thought I was in there she pushes me away and tells me to go and fuck the little blond."

"And did you?" Mark asked him.

Elliot narrowed his eyes at him. "No, I didn't. Despite what my wife thinks I love her. But a man has needs and if she is going to keep accusing me then," he shrugged his shoulders. "Then why not get some."

"You mean you would actually cheat on your wife just for sex."

"Well is there any other reason," he smirked. "Anyway no harm will be caused as long as she doesn't find out."

"And what if someone tells her."

Elliot stood up and stepped towards Mark glaring at him. "And who would do that?" he asked him as he backed him up towards the wall.

"I …I was just…Just saying," he stuttered.

"Cause I thought we were friends, just two guys talking. I would hate for you to go behind my back and tell her, and I'm sure the rest of the guys in the unit wouldn't be impressed by that either," Elliot warned him his voice threatening.

Mark swallowed hard. "I wouldn't…I swear."

"Well that's okay," Elliot grinned patting him on the shoulder. "And as we are friends then you won't mind me using you as an alibi…Will you?"

"No….That's fine."

"Good," he grinned taking out his phone and Mark stood watching him. "Hey Amanda its Elliot," he said after a few seconds. "Yeah I'm good, how are you…..Listen you left a few things at ours after the party the other night….Yeah, sure, my wife will be out at work but I will be in," he laughed softly down the phone. "I figured we could maybe pick up where we left off by your car the other night…"

Mark stood to the side listening to him; Elliot turned his head towards him and covered the mouth piece slightly.

"You can fuck off now," he told him.

"Erm yeah….sure," he said walking away.

Elliot watched him as he walked away and saw him glancing back at him.

"He gone," Olivia asked him.

"Yup and he gave me the filthiest look as he did."

"So he fell for it then."

"Oh yeah, he fell for it."

"Well I guess you need to call Amanda then and arrange her coming over then," she said and Elliot heard the change in her tone.

"Liv….."

"Just make the call Elliot," she said hanging up.

"Shit," Elliot sighed putting the phone in his pocket and climbing in his jeep.

John and Fin both turned when the door to the apartment opened and Olivia walked in.

"Is it not a bit risky you coming here," John asked her.

"You hired me as a cleaner," she told him dropping the large bag with cleaning products in.

She pulled up a chair and sat down next to him and Fin. "So what's happening?" she asked them looking at the screens and into the home she was currently sharing with Elliot.

"Just waiting for Amanda to turn up," Fin told her.

"Your husband is currently in the shower."

"Great," she mumbled sliding down in her chair slightly her eyes fixed on the screen with the master bedroom on it.

A few minutes later Elliot came out the bathroom with only a towel around his waist. Olivia sat up slightly her eyes fixed on him as he dried himself off. He turned his back to the camera and pulled off the towel. Olivia swallowed hard and bit down on her bottom lip as her eyes moved over his body and staying on his ass a little too long.

"Did Stabler know you would be watching?" grinned Munch.

"What?" she asked as she watched Elliot put on body spray.

"I was just wondering he doesn't normally wander around naked.

"Hmmmm, yeah," she replied not listening to him as Elliot picked his jeans up from the bed and pulled them without putting on any boxers. He turned around and looked towards the camera and smiled.

Olivia groaned as she felt a dull throb between her legs.

"You okay there Liv?" Munch asked her when he heard her groan and Fin couldn't help but laugh.

"What? Yeah I'm good," she said blinking and shaking her head as Elliot pulled on a plain white t-shirt.

"Looks like Stabler got dressed just in time, his guest has just arrived," Munch informed everyone as Amanda come into view on the camera above the door.

"Great," sighed Olivia standing up and walking over to the pot of coffee. Munch and Fin looked at each other and smiled as they shook their heads. This could turn out to be a fun night.

Xxxxxxxxxxxxxxxxxxx

"Hey," said Elliot stepping to one side.

"Sorry I'm late," she smiled walking past him brushing up against him slightly.

"It's okay," he said following her into the living room. "At least we know he should be home and hopefully watching us. Can I get you a drink?"

"Sure a wine would be good," she smiled at him. "It might help me relax a little."

"Your nervous?" he asked her as they walked into the kitchen.

"Yeah a little. I have done undercover gigs before but nothing like this."

Elliot chuckled as he poured the wine out for them.

"It is a little different," he said handing her the glass and then stepping in front of her. "But to make this look realistic your gonna have to relax."

"That's easier said than done," she said taking a drink. "Especially knowing Munch is listening and watching everything we do, along with that creep."

"Yeah well creep umber one can't hear us and try to forget about creep number two," he laughed putting his glass down and running his fingers lightly up her arm. "Our job is to make Mark believe we are having an affair so he….So he goes after Olivia to teach me a lesson."

"And you're okay with that?"

"No," he said moving forward slightly and taking her glass from her. "But we have a job to do and that's what needs to happen."

Amanda nodded slightly as he put the glass down.

"Now do you think you can do this?" he asked her as he caged her body with his arms.

"Like you say we have a job to do."

"So how do you want to do this?" he asked her, he knew from behind and the view Mark had this would look like they were flirting.

"I guess we just need to go for it," she smiled. "Olivia is gonna kick my ass no matter how we do it."

Elliot couldn't help but laugh.

"Okay. A small make out session now," he said. "Just to get things going, Munch has been told to make a call to interrupt us."

He looked into Amanda's eyes and saw how nervous she looked. "Just relax, and try to make it look as though we are both into it" he told her cupping her cheek as he leant in and pressed his lips against hers.

Xxxxxxxxxxxxxxxxxxx

Olivia glared at the screen as Elliot leant in and kissed Amanda. His body blocked out a lot of what was happening, but from the angle they had and Mark had it looked real enough.

"You sure you want to be here?" Fin asked her. "We have managed the last few weeks alone."

"I'm sure!" she snapped as Elliot ran his hand down Amanda leg and lifted it up and around his waist.

"You okay," they all heard Elliot mumble as Amanda's fingers brushed lightly down the back of his neck.

"Yeah, I'm good," she replied. "Do you reckon he is falling for it, that it looks real enough?"

"Looks real enough to me," grinned Munch dipping his hand into the popcorn bowl and earning himself a filthy look from Olivia.

She had been indecisive about watching what went on in the house between Elliot and Amanda and twice she had stopped the car and turned it around only to do another U turn and head to the house.

Xxxxxxxxxxxxxxxxxxx

"Maybe we should notch it up a level," said Elliot as he lifted her other leg and she wrapped it around his waist as he lifted her off the bench with ease.

"What the hell Stabler," she laughed as he carried her to the living and dropped her on the couch directly under the camera Mark had hidden.

"Hey, I'm supposed to be a horny husband who isn't getting any, I gotta move quickly," he told her as he dropped down on top of her and his lips went to her neck. "Munch make the call," he said against her skin as she ran her hands down his back and under his t-shirt.

Elliot squeezed his eyes closed as her nails dragged over his skin. He knew they were only acting but images of Olivia lying under him flashed though his head, her naked body writhing below him as her hands explored him. He imagined how he would explore with his mouth and tongue taking his time with her.

"Fuck!" he grunted against Amanda's neck as he felt the start of an erection push against his jeans. "I'm sorry," he mumbled as his fantasies of him and Olivia got him worked up.

"It's…..its okay," she mumbled when she felt what he was apologising, before he pushed himself away from her.

"I'm gonna kill Munch," he panted as he looked down at Amanda's flushed face and picked up the house phone that wasn't even ringing.

Xxxxxxxxxxxxxxxxxxx

Olivia's eyes flicked back and forwards to the screen as Elliot carried Amanda to the couch and put her down and crawled on top of her.

She heard the words "Munch make the call," before she turned away from the screen unable to watch them together no matter how much of it was just an act. She didn't turn back around until she heard Elliot curse the word "Fuck," then "I'm sorry before she turned back around.

"Guess the acting went a little too far," laughed Munch as Elliot pushed himself up and went to the phone as he mumbled something about killing Munch.

Olivia watched him as he answered the phone that wasn't even ringing pretended to have a conversation, as Amanda sat up right and straightened her clothes. Her eyes went back to Elliot as his free hand moved to his crotch and she saw him press against his growing erection as he looked towards one of the hidden cameras, before dropping his head against the wall as he took deep breaths, to try and calm himself.

"I guess that's my cue to go," Amanda said from behind as he hung up the phone.

"Yeah…Sorry about that," he said as he turned around. Amanda shrugged and smiled.

"No apology needed," she said smiling at him.

"Oh I don't know," he smiled back, and Olivia watched him lead her to the door.

"So what now?" she asked when they were out of sight of the camera.

"I will leave for a while I guess, so he thinks that was what the call was about."

"Okay, I will head back to the station and see what Cragen and Dana want us to do next."

"Amanda, about what happened," he said sheepishly. "Could we keep it between us?"

"My lips are sealed," she told him. "However if you don't want Olivia to find out you best have a word with Units very own pervy old man," she said as she walked to her car.

"Yeah," he mumbled closing the door and heading back into the living room. Olivia watched him as he picked up the phone and pretended to make a call as he looked towards one of the cameras. "John, lose the footage," he warned him. "I swear to god if Olivia sees that, you will find out firsthand what happens when you finally die."

John and Fin both turned to Olivia who was stood behind them pulling on her coat then she turned quickly and left slamming the door behind her.

"Oh boy," sighed Fin slumping into his chair."Do you think we should warn Elliot?"

"Yeah," said Munch picking up the phone. "Although I don't know what good it will do him."

Xxxxxxxxxxxxxxxxxxx

Elliot sat nervously on the couch waiting for her to come home. Munch had called him straight away and told him Olivia had seen everything that had happened. That had been over two hours ago and she still hadn't arrived back. He had tried to call her several times but got no answer. He had then called Cragen worried that Mark may have taken her. Cragen had made some calls himself then called Elliot back and told him she was safe and was just at work. The guys watching Marks place said he had left and gone into work. Elliot had then left the house for a while and since he had gotten back he been waiting on the couch for her. Cragen had informed him Mark still wasn't home as he had gone to a bar after work.

He jumped up when he heard the front door open and slam shut.

"Hey your home," he said walking towards her and away from the camera Mark was watching them on and reached for her.

"I'm tired and need a shower," she told him pulling her arm away from him.

"Liv, we need to talk," he said reaching for her hand but she pulled it away.

"There's nothing to talk about," she said walking away from him and towards the stairs.

"I know what you saw, and how it looked," he said after her and she topped in her tracks half way up the stairs. "But I swear to you, it was all just an act."

Olivia laughed as she turned to face him. "Just an act?" she asked him.

"Yeah….we had….we had to make it look real."

"Oh I would say you both done that okay. The evidence was there for everyone to see!" she yelled turning back around and running up the stairs. She heard Elliot following her as she entered the bedroom and slammed the door in his face.

Elliot turned the handle and barged in.

"Get out," she told him.

"No we are going to talk," he said stepping towards her.

"There is nothing to say."

"You knew the plan," he said ignoring her. "You knew we had to make it look as though we were having an affair, what was I supposed to do sit her down at the table and make her a cup of fucking tea?" he asked raising his voice. She never spoke but just stood and glared at him."Do you honestly think I wanted to have to do that or Amanda did knowing people were watching us. It was the most uncomfortable thing I have ever done before," he said stepping towards her.

"I'm not surprised," she said her voice low. "Especially with that raging hard on you were trying to hide."

"Liv, it wasn't like that," he tried to explain but she just laughed and shook her head.

"No it was exactly like that," she said staring him in the eyes. "I guess it was just all bullshit about not wanting a blond anymore."

Elliot narrowed his eyes at her. "You really think I wanted Amanda?" he asked her and Olivia just shrugged.

"I think that erection you tried so hard to hide answers that question," she said storming off into the bathroom and slamming the door behind her, so he couldn't see the tears that were falling.

"Like hell it does," he said to himself as he remembered the thoughts in his head that had caused his erection in the first place. He stood looking at the door as he heard the shower running. He closed his eyes and bit down on his bottom lip as images of Olivia naked and wet in the shower ran through his head.

"Fuck this," he said to himself as he walked towards the bathroom and entered without even knocking.

Well I guess it's gonna be time to finally up the rating can't keep them apart much longer.
