The Thing They Have

Summary: The 'thing' between Deeks and Kensi finally works out, to some degree.

Everybody knew there was a 'thing' between Deeks and Kensi. Since the day they met, there was a 'thing'. Sam and Callen saw it in the boathouse when they officially met LAPD Detective Deeks. They even teased her about her attraction to him when they met while undercover. She was stuck or smitten as Callen called it by him. Then Marty Deeks became their liaison with LAPD. Hetty partnered him with Kensi and the 'thing' grew into all out sexual tension between them.

Bets were started all around when this 'thing' was going to be settled. Even Ray, Marty's best friend, wanted to know how the 'thing' would work out. "There's no thing," Deeks said. He seemed to be the only one who didn't see it. Kensi saw it and she made it a point to drive him crazy with each passing day until this 'thing' was settled.

Deeks' breaking point was during an undercover op that required him and Kensi to pose as lovers. The suspect they were after frequented a night club and they were going in to be the eyes for OSP. He knew that Hetty was going to dress Kensi to the nines for this op. He just wasn't expecting her to step out in the little black dress that made her look even sexier than before. He had turned around and forgotten to breathe at the sight of her. Black pump stilettos that adorned her feet made her legs go on forever. "Definitely a thing going on between them," Callen had quipped. Deeks sharply turned around to snip back.

"There is no thing." He and Sam nodded as if they didn't believe him as he walked up to his partner. "Nice dress or what's left of it," he teased.

"Thank you, Deeks," she said.

In the nightclub, Deeks and Kensi were glued to each other's side as they posed as a couple. They both had only one drink before they hit the dance floor to entice the suspect out of the crowds. Outside in the Charger, Sam and Callen watched from a camera that Deeks had planted to view the club. "That 'thing' they have going on is going to resolved by tonight," Sam said. "That body language speaks sex in volumes," he added quietly so their team mates didn't hear them.

"Tonight?" Callen asked. "No way," he said.

"Fifty bucks," Sam said holding out his hand.

"You're on," Callen said before shaking hands with his partner.

Back inside, Deeks was having a hard time concentrating with Kensi this close to him. He risk a glance around and spotted their suspect coming out from the back. "I got eyes on Karson," he said bringing Kensi around so she could see. Just as Kensi focused on Karson's face, Karson looked up and made eye contact with her. She did the only thing she could think of and pulled Deeks' head down. Their lips met in a heated kiss and Deeks was surprised at first, but then relaxed into the kiss. He meld his arms around Kensi and pulled her closer. Callen cursed to himself seeing the two partners kissing to keep Karson suspicious as Sam held out his hand for his money.

"No," Callen said. "This doesn't mean they're going to have sex."

The two partners pulled away from each other when they were given the green light that Karson had turned around and was leaving the club. Deeks breathed out a sigh as Kensi smiled wickedly. "Still think there's no thing between us?" she asked.

"There's no thing," he said. "That was all an act," he said causing her to chuckle. He swallowed down his nerves before they headed after Karson.

After Karson's arrest, Deeks and Kensi were changing from their club outfits. He found it difficult to change knowing that she was next door to him either naked or in just her skivvies. He finished changing and hurried back to his desk. "That was some kiss you and Kensi were sharing in the club," Sam said as he sat down next to him.

"She caught me by surprise with it," Deeks said trying to laugh it off.

"Doesn't help when you two have a …." the ex-Navy seal started to say.

"There is no 'thing' between Kensi and I," Deeks said before grabbing his bag and leaving the bull pen. He stopped short almost running into Kensi. She was wearing those jeans that looked incredible on her. The top wasn't too bad either. "Sorry, Kensi," he said as he pulled his bag over himself. He didn't need her to see what had was tenting in his jeans since her hands flew to his hips when they danced. "I'll see you on Monday," he said before hurrying away. Kensi looked over at Sam and Callen.

"What did you two do?" she asked.

"Nothing," Sam said.

"You mentioned the thing," Callen said not looking up from his paper. Kensi crossed her arms and looked at Sam sternly.

"You know he hates it when you guys mention the thing between us," Kensi said.

"Yeah, but it's fun seeing his reaction to it," Sam said.

"We also like it when he tries to deny you two have a thing," Callen said. "You better do something this weekend or else he's going to burst."

"What do you want me to do?" she asked. "Jump him as he's coming out of his shower tonight?"

"Not a bad idea," Sam said smiling at Callen. Kensi groaned as she grabbed her bag and headed out.

Deeks entered his apartment with a huge sigh. "Made it," he sighed out before locking his door and deposited his bag on the floor. Upon entering the kitchen, Monty came in from the back porch and wagged his tail. "Oh, Monty," he said out loud, "Daddy's got a thing for Auntie Kensi," he said. He gave the dog a rub behind his ear before giving him his dinner. He was debating between making himself something or ordering out until he looked to see the tent in his jeans. He's had it since Kensi and him were bumping and grinding against each other in the club five hours ago. He glanced at the clock and saw it was too late to order out and he didn't feel like cooking either. He headed into his bedroom and began stripping his clothes off. He sighed in relief getting his jeans off before taking off the rest of his clothes. Cold showers usually worked for him.

Stepping into the shower, he turned the cold water and gasped when it made contact. He moaned softly still feeling her hands on his hips from the dance. He kept his hands on the walls letting the cold water do it's job. He thought of everyone he worked with wearing a bikini, even Hetty. All that did was bring up the little pink bikini that Kensi wore on another undercover op.

He groaned in despair as his cock reacted to the image in his mind. The cold water was going to fail him tonight. He roughly turned on the hot water and leaned his head against the wall before grasping his temperamental cock. He gave it a few strokes as he imagined Kensi in the pink bikini again and this time, they were alone on the beach and she was straddling his waist.

Deeks groaned as he gripped both the edge of the wall and his member. He gritted his teeth, groaning out Kensi's name. He imagined her hands in his swim trunks and gripping his member with her slender fingers. "Oh, shit," he muttered. He sped up the strokes on his cock as he imagined Kensi going down on him right there on the beach. Marty let out a gasped moan when his orgasm hit him out of the blue. He let out a sigh before rinsing himself off and finishing his shower.

Once he was done, he turned the water off and wrapped a towel around his waist. Stepping out of the bathroom, he stopped short in his tracks seeing a very familiar person on his bed.

"Kensi?" he asked gripping his towel tighter around his waist. "What are you doing here?" She chuckled wickedly causing Marty to swallow nervously.

"I'm hear to rock your world, Detective Deeks," Kensi said. Marty chuckled nervously keeping a hold on his towel. He was in for a long night.
