Rating: Mature… obviously. So if you can't handle it, please don't read it.

A/N: Dedicated to Ashley, Julie, and everyone else who keeps reading my stuff even after I don't write for ever. Also, I didn't intend a couple of things for this story: 1) for Sara to be so brazen. It just happened and 2) For it to be longer than one chapter but I think I'm going to make it kind of a thematic story… that sounds weird since a lot of stories have themes but you'll see what I mean.

Workout: Bump and Grind

It was probably to do with the case that Nick had had a week ago where he had to witness a crane removing a severely overweight dead man from his house, for why Nick was walking into his local gym and reluctantly getting a new member card since his previous one had expired.

"Have seen you in a while," flirted the young brunette behind the counter, flashing her chestnut eyes up at him and snapping her gum in her mouth before changed something on her computer screen.

"You know how work is," he offered back, leaning lazily on the counter and glancing over at the pool in the background where kids were jumping in and splashing around.

"How late are you guys open until again?" he wondered, rifling through a stack of pamphlets for a schedule.

"Midnight. I'll be here until then too."

He could have sworn that he saw her wink but he just thanked her when she handed him his new card instead of commenting on it.

"Have a good workout, Mr. Stokes."

As he pushed open the heavy glass door, he murmured, "Overeager receptionist."

It was the same old gym as he had remembered it, filled with the usual familiar faces of the men that pumped iron and flexed their muscles every time a female walked towards the door or the drinking fountain that happened to be in the heart of the plethora of testosterone-driven sweaty beasts. Finding an empty cubbyhole, Nick set his keys, wallet, and extra water bottle in it before making his way to the cardio machines where the women flocked. He always found it better to run for a bit first, staring at the moving behinds of the women using the treadmills in front of him, before moving to the weights where the men were.

Nick set his water down in the folder and his towel over the railing of the machine as he punched in his weight and age, picking his program. He was glad that he remembered his iPod that his sister gave him last Christmas since the televisions were always playing rap, CNN, or Gilmore Girls. Not that he minded the latter since he found the mom rather attractive and not to mention the innocent daughter who was well past the age she was playing on the show.

Sure enough, when he looked up at the TVs after he began running, he saw Gilmore Girls and let out a small chuckle, noticing that most of the women seemed to be watching it as well.

It wasn't under the episode was over that Nick realized that he had been running nonstop for twenty-five minutes and was drenched, his grey Crime Lab t-shirt sticking to him uncomfortably. He took another gulp of water as he slowed down the treadmill to a slow walk before hitting the 'stop' button a couple minutes later. He wiped down the machine with the paper towel and cleaning solution the gym provided before stretching out his leg muscles and his arms, eyeing up the bike that was a couple feet away from him.

As he sat down on the bike, he couldn't help but notice the woman in front of him on the elliptical, completely dominating the machine (A/N: Word doc. didn't like "just giving 'er"). He could see the muscles of her legs flex and contract with every step that she took and her ass moving in the slightly loose black shorts that teased the back of her thighs. Her brunette hair was perched on top of her head in a messy bun, tickling the back of her neck, damp with perspiration.

Unconsciously licking his lips, Nick peddled faster as if it was going to bring him closer to her. It was why he always enjoyed the cardio machines and didn't care if the disgustingly huge guys lifting weights on the other side of the gym made fun of him because while they were grunting and staring at each others biceps, Nick was drooling over the plump behind of the girl on the elliptical before him.

There was a slight ache in his lungs that had started near the end of his running. He definitely needed to frequent the gym more if he was already panting since normally he was much more intense in his workouts. It was a definite advantage for him to be fit for his job since he could count on both hands how many times he had to run after someone for some reason or another while he was at a crime scene or trying to question a witness at their house, who was busy jumping out the back window and scaling their fence.

If going to the gym more meant being able to stare at her fine body, her arms lightly toned along with her calves, Nick was definitely in. He realized that she was suddenly slowing down and done her workout, much to his dismay. When she got off and made her way to the paper towel dispenser, walking right past Nick, his jaw dropped, nearly hitting the handles in front of him. He turned his head the other way, keeping it low. He couldn't believe that for the past ten minutes he had been salivating over Sara Sidle's body, especially her ass.

"Nick?" questioned a familiar feminine voice from behind him. "Is that you?"

He kept cycling, keeping his head low and thanking God that he had headphones plugging his ears. For once, he noted that listening to loud music was a good idea since he could always blame not hearing things on his iPod.

However, when he felt a delicate hand rest on his shoulder and saw her cute, little runner-clad feet in his line of sight, he sighed to himself, looking up into chocolate brown eyes and a smiling white mouth.

"Sara, hey," he greeted, immediately feeling a flush rising from his neck to his cheeks as he took out his headphones. "I didn't know you came here."

"I didn't know you went her either," she replied, withdrawing her hand from his shoulder. "How come I've never seen you here before?"

"Because I haven't been here in about six months," he chuckled, still cycling lightly.

"What happened? That's not like you," Sara teased before taking a sip of water.

Nick watched in slow motion as Sara's head tipped back while her hand raised the bottle to her lips, which where parted in a way that could only be seen as sexy. A little droplet of water escaped and slid down her chin to her neck before teasing the hem of her scooped t-shirt. He felt like he was watching some Gatorade commercial on television. He made sure to pick up his jaw again before she looked back at him.

"Um, you know…" he trailed off, shrugging. "Work, I guess."

"Right, work," she smiled. "What changed? It's not even close to New Year's."

Chuckling, Nick slowed down to a halt on the bike before getting off on the same side as Sara was standing. He didn't realize how close she had been because she had to take a half step back in order for him not to completely have run into her. She was still close enough that he could smell her feminine scent mixed with deodorant and sweat, her breath faintly caressing his neck as she looked up at him. Neither of them realized until now how much taller nick was compared to her. As much as Nick could have stayed as close as he was to her, pulled her even closer into his arms before possibly dragging her to the closest wall to take her against, Nick didn't feel like having people stare since the tension was evident. So he excused himself, brushing past her chest accidentally, and went for the paper towel, noticing that only the girl next to him on the bike had been watching, no doubt with the volume turned down on her CD player.

He wiped down the bike and then asked what Sara was planning on doing next as he sipped his water.

"Well, I was planning on using a couple of the weight machines. What about you?"

"Yeah, me too," he lied, following her over.

While Sara went on a machine that explained why her biceps were so toned, Nick chose the one across from her. He didn't really pay attention to what he was doing, just as long as it meant he could watch Sara. Once they were finished on the weight machines, she insisted that Nick did free weights with her. As he made a grab for two thirties just to warm up with, he laughed when she went for two tens.

"What?" she pouted, sitting down on the next bench. "I'm sorry I'm not as big and strong as you."

"I'm glad you're not, Sar. That would be very awkward."

"Why?" she teased, raising her eyebrow mischievously.

"No reason," he smiled, shrugging it off as he continued to lift the weights.

"Afraid I'd beat you in wrestling or something?"

"Now why would be wrestling?"

"No reason," she replied, mimicking his very actions.

Nick watched as Sara changed positions, facing him. She had one knee resting on the bench while her other foot was on the ground as she lifted the weight, giving Nick a glorious view of her cleavage. She glanced up slightly, wondering if he'd taken the bait.

"You know Nick," she began, slightly panting for dramatic effect, "I usually go into the sauna after workouts. Would you care to join me?"

"Sure, Sar. I haven't been in one for ages."

"Want to go now?" she asked, looking into his eyes, completely catching them elsewhere than her face.

"Sure, Sar."

It took them a couple minutes to collect their things and then change into bathing suits. Nick noted that it was rather unfortunate that there weren't unisex changing rooms. He glanced at his watch before he shoved everything into the locker and deposited fifty cents. It was nearly ten thirty, which meant that the pool and sauna would hopefully be nearly deserted.

Nick waited for Sara outside of the two entrances until she came out wearing not much at all. Her bikini was black, not a color he would have expected, and tied up around her neck and her back. It was rather plain since chlorine tended to damage nice bathing suits but it was enough to get Nick's heart pumping faster as she led the way to the sauna room. He couldn't help but notice that the bottoms were slightly too big for her around the waist, but he decided that she did that on purpose since she could have adjusted it on the sides.

"How come you go into the sauna afterwards?" he asked, just before the stifling air clogged his lungs. "Don't you get sweaty enough from your workout?"

She shrugged, sitting in the corner on the top bench with her legs stretched out. He decided to mirror her position since they were the only ones in the room.

"It's just nice. Helps me relax even more," she murmured, leaning her head back against the wall.

"I know what would help you relax even more," Nick drawled, folding his arms over his bare chest.

"What's that, Nicky?"

"A massage."

One of her eyes opened half way to peer at him. "Are you offering?"

He shrugged. "Sure."

It took ever ounce of will power in his body to not throw her down and take her right then and there when she crawled over to him like the little vixen that she was. It seemed to be a popular thought of his that evening: taking her wherever they were. He was moderately surprised to see such a brazen side of her because at work, she was confident but not exactly outgoing and playful like she was being tonight. He just attributed it to her work state of mind since they had a serious job.

"How do you want me?" she asked innocently.

"Excuse me?"

"Well, do you want me to lie down or do you want me to sit in front of you."

"What ever way you're more comfortable."

"Okay," she smiled.

He wasn't expecting her to crawl into his lap, practically straddling him.

"What am I massaging, Sara, your breasts?" he jested.

"You're the masseuse, Nicky."

Nick placed his hands lightly on her hips, beginning to rub circles into her flesh before he moved his hands around to the small of her back.

"You're not bad," she purred, hanging her arms loosely around his neck.

"Neither are you," he grinned up at her, watching her eyes flutter shut when he reached her shoulders.

He massaged everywhere but her breasts, trying to be a gentleman in some ways and knowing that it was hopefully killing her in other ways because he wasn't giving her what she wanted. When he rubbed her sides, just under her armpits, she tried to move into his palm but he held her still.

"Want something?" he asked hoarsely, trying to clear his throat.

"Nicky, I've always wanted something."

"What's that Sara?"

Her eyes were open and gazing down at him, making him melt. If she hadn't felt a nudge against the apex of her thighs, she could definitely feel one now.

"Please," she whispered.

"What?"

Him feigning ignorance wasn't exactly the easiest for him to do since he desired what she was yearning for so badly. He licked his dried lips and concentrated on his hands and how they had traveled down to her hips, which had began to rotate and grind down on his lap.

"Sara," he groaned, "you can't do that."

"Why not?"

"Not here."

"I like it here, Nicky. It's nice and warm and we're all alone."

"Until someone walks in."

"We're not doing anything wrong. You're just giving me a massage."

"I'll be giving you a lot more than a massage in a minute."

"I hope so," she flirted back, smiling deviously.

He sighed and leaned his head back against the hard wood of the wall, keeping his hands at her hips in no attempt at stopping her motions. He wasn't aware of what she was doing with his hands until he felt plump flesh beneath his fingers and heard a soft, almost inaudible groan come from the woman in his lap.

It took him two seconds, maybe three, to get her top off and have her pressed against his chest with his mouth fused to hers. She barely even knew what happened until she felt his hot lips on hers, kissing her for all she was worth.

"Took you long enough," she breathed out after a moment.

When she withdrew slightly to talk and possibly breathe. Nick couldn't help but stare at her bare chest, having remembered that he had deftly removed it before kissing her.

"What?"

Her eyes followed his and she squealed a little before her hands flew up to her cover herself.

"Uh, no. I don't think so," he growled, prying her hands away.

"Nick!"

"You wanted me to touch them so I'm going to."

With one arm around her back and the other practically glued to her right breast, Nick found purchase in how her nipple felt in between his teeth. Apparently, she enjoyed it as well.

"You wouldn't believe if I told you how long I've been dying to do this, Sar," he mumbled, kissing the side of her chest.

"I would."

He glanced up at her, causing her to giggle since he had a mouthful of her breast.

"Nicky, I don't go to the gym."

"What?"

"I asked Warwick a few months ago, what you gym you went to and I've been going ever since."

"Why?"

"In hopes of 'accidentally' bumping into you."

"Well, you sure bumped into me Sar," he replied, pressing harder against her.

Chuckling, she grabbed his face with her hands and kissed him.
