She was driving him insane.

He was supposed to be focusing on the files in front of him, but all he could think about was the fact that she was driving him positively and utterly insane.

It was a slow shift for once, and the intense summer heat was getting to the entire lab. The air conditioning system had broken down hours ago, and apparently no one found it necessary to have it fixed in the middle of the night. The rest of the team had gathered up in the break room, which was undoubtedly the most comfortable room in the lab at the moment. What they were actually doing, though, he didn't know.

No, he had for some unknown reason decided to retire back to his office to finish up some case reports and he'd necessarily had to bring her with him.

Perched on the edge of his desk, she was teasing him mercilessly with the divine view of her bare legs only inches away from him. I was not often that Catherine wore skirts to work, but the sweltering heat had seemed to offer her no other choice. The exposed skin seemed to be calling to him, the white, flowing material of the skirt ending just above her knees. The fact that he imagined that he could see right through that tight halterneck top she was wearing with it hardly helped matters either.

Yes. She was driving him absolutely insane.

He knew she could feel him staring at her, and he did not want to give her that satisfaction, and thus he forced himself to look back at the file in front of him again. His eyes drifted over to those oh- so inviting legs a few more times before he was finally able to at least half focus on the work he'd set out to do.

Minutes passed, and he actually thought he was doing rather well. He could still see her in the corner of his eye, but he'd be damned if he let her catch him staring at her again.

That's when she did it. She re-crossed her legs, accidentally brushing her bare foot against his groin in the process. His eyes shot up to her, but she was still engrossed with the file in her hand, her teeth biting down on the pen she held in her other.

Accidentally his ass. He knew she wasn't nearly as innocent as she looked, but against better judgment, he decided to give her the benefit of the doubt, once again turning back to his own case report. He could've sworn he saw the corner of her mouth twitch as he did, but already knew it would be gone by the time he looked back at her.

`Focus, Gil,' he thought to himself, staring intently at the swimming words in front of him. Shaking his head slightly, they finally un-blurred, and once again, his intentions lay solely on finishing the task at hand.

That was until she `accidentally' brushed her foot against him again, this time pressing harder against him with the ball of her foot before releasing pressure, and he felt himself immediately react to the intimate contact.

`Okay, that's it!' he silently said to himself, never averting his eyes from the folder in front of him. `Two can play this game.'

This time he was more than certain that he could see a smirk forming on her lips, but he continued to ignore her as her foot finally left him to dangle next to her other one.

He was now beyond being able to focus on work again, but he was not about to let her know that. No, she had started this thing, but he would be the one to finish it. Letting several minutes pass by, he pretended to be engrossed by whatever the file in his hand was trying to tell him. In reality, he no longer had any idea what it said; his mind was occupied with other thoughts. Thoughts that had absolutely nothing to do with work.

When he was sure she'd bought his act, he suddenly rested the palm of his hand lightly against her bare knee. His left hand was still holding the folder, and his eyes were still firmly fixed on it, but his right hand was making its own little journey. He desperately wanted to smile triumphantly as he felt her twitch slightly under his touch, but bit it back.

Drawing slow circles on the inside of her knee, he could feel the heat rising even further in the confined office. The fact that she had closed the door, as well as the blinds, behind them as they had entered it earlier hadn't registered with him until now, and if he could have done so without betraying his cool exterior, he would have smiled at her foreseeing.

Instead he `rewarded' her by allowing his hand to inch further up her leg, beginning to disappear underneath her skirt. He trailed a slow path along the inside of her thigh, and he had to hand it to her. She was good. Folder still firmly planted in her hand, she was no longer biting on her pen, but he'd be damned if she didn't look like she was still reading.

Yes. She was definitely good.

But if there was one thing he knew, it was that even Catherine Willows had her limits. And he had found that he just loved pushing them.

His hand traveled higher and higher, almost painfully slow, until his ministrations were finally rewarded as that first sign of surrender came. It was barely noticeable, but with no help from him, her legs nudged apart just the tiniest bit, allowing his exploring hand better access to where they both knew it was headed.

Inching further and further, her smooth skin burning against his palm, he finally reached his final destination, finding nothing but soft, hot flesh and a patch of unruly curls.

Oh God, she wasn't wearing any underwear. He racked his brain, trying to recollect a memory of her being out of sight long enough to remove it, but quickly realized that she had to have been without them all shift. He had to bite his cheek to keep himself from grunting at the thought of her having sashayed around the lab all evening, wearing absolutely nothing underneath that thin fabric.

Had he known, she would've had him long before now. She'd been swaying those hips at him, flirting oh-so innocently; a touch here, a touch there, anything to pull him closer, yet keep him at a distance. Oh, she had known damn well what it would do to him to make this discovery. `Good' didn't even begin to describe her. `Evil' was more like it. And he was loving every second of it.

He stayed completely still for several moments; to let himself to cool down or simply to keep her guessing, he didn't know. It didn't matter. He couldn't wait to taste her; to taste that tangy, smoky essence that was pure Catherine on his tongue. But he wanted her to beg him for it; for her to lose that control she was so desperately holding onto.

He let his finger glide through her already slick, wet folds, briefly wondering if he'd ever stop being amazed that this incredible creature had this reaction to his touch. He guessed not. Continuing his quest, he circled her clit with his thumb, making sure he was avoiding direct contact. His hand slid back to the inside of her thigh again, squeezing it firmly yet gently, before once again returning to her wetness, sliding his finger up and down.

Finally risking a glance at her, he smiled. Her eyes were still focused on the document in front of her, but they were glazed over and no longer moving, instead staring intently ahead. She was biting down on that full, ripe lower lip of hers; her chest was heaving with short, deep breaths, and she was the most erotic thing he'd ever seen.

Pressing his thumb against her, he slipped a finger inside of her.

She moaned.

He smirked.

Jackpot.

- - - -

He was driving her insane.

Her entire body was on fire, humming from his touch.

She honestly hadn't thought it would go this far. Well… not thought it, but certainly hoped for it. She knew exactly what she'd been doing all day, and she'd done it all on purpose; everything from her clothes to the way she'd acted around him had been carefully calculated, all to lead to this very moment.

She just hadn't thought it would actually happen.

His finger inside of her was very real, though. As was his hot breath against her thigh. She finally looked down at him and met his ocean blue eyes, and the look in them made her breath catch in her throat. It was nothing other than predatory. She ran her tongue over her bottom lip, and his eyes darkened further. He'd never looked sexier.

He suddenly stood up between her legs, his hand still firmly positioned against her center, and she held her breath. He loomed over her, his mouth a mere inch away from hers, and she closed her eyes in anticipation. But the awaited contact never came, as he moved down to press his lips against the hollow of her throat, sneaking out his tongue for a quick taste. Her head lolled back involuntarily to grant him better access, and he pulled away immediately.

Her eyes shot open, only to find him giving her wicked smile. A low growl escaped her as she frowned at him, and the bastard had the audacity to chuckle at her. Then he curved his finger inside of her, hitting just the right spot, and her growl turned into a deep moan, her head once again helplessly falling back.

She felt his free hand go up behind her, as his other continued moving against her, inside her. He tugged at the thin straps that were tied around her neck, and the top fell effortlessly from her heaving chest, pooling around her slim waist.

Eyes still locked, he skillfully unclasped the strapless bra covering the soft flesh of her breasts, throwing it carelessly to the floor. She loved this side of him; the primal side she knew few had witnessed, but that always lurked beneath that calm, collected surface.

His hand found her right breast, kneading it with a gentle roughness that she would forever associate with him, his fingers playing with her already taut nipple. She watched as he leaned forward, pulling it in between those lush lips she couldn't get enough of, suckling it, and the second she arched into him, he pulled away.

Oh yeah. He was driving her absolutely insane.

"Fuck you, Gil," she muttered.

"All in due time, my dear," came his charming reply.

"I hate you." She glared at him.

"As much as you hate this?" And with that he plunged a second finger inside of her, curling them both upwards.

"Yeah," she gasped, her head falling forward to rest on his shoulder, as he moved his fingers inside of her. "I hate it." He knew just how to touch her, just how to hit those magic spots that made her melt into his hands. It was the sweetest hate ever known.

She turned her head into the crook of his neck, nuzzling into him, before tracing his strong pulse with her lips. Her tongue snaked out to lave at his skin, and when he groaned, she knew he was beginning to break. She nipped her way up to just below his ear, taking his earlobe between her lips, sucking it lightly, and his fingers began to thrust faster in and out of her dampness.

He shifted slightly and growled into her ear. "Damn, woman…"

She would've giggled if she hadn't been so damn aroused she could hardly remember how to breathe. Reaching out, she ran her sharp nails over the hard bulge hidden only by his now seemingly too tight khakis. He bucked into her hand, desperately seeking more pressure, before roughly pulling away from her again, grabbing her wandering hands in his own. When he removed his fingers from her, she could've hit him for depriving her of the intense pleasure he'd given her only mere seconds ago.

"No touching," he said, and she offered him her best pout, but it did no good. Leaning forward, he mimicked her earlier move, biting down gently on her earlobe, before adding, "And no moving." With that he placed her hands down on the desk next to her sides.

Holding her breath, she watched with big eyes as he grabbed her knees, pushing them apart further, kneeling down between them. He bunched the skirt up around her waist where it joined the forgotten top, exposing her fully to him. Arms going under her legs, he reached around her, and suddenly her legs were dangling over his shoulders as he yanked her up to the very edge of the desk, and she held on for dear life.

"Don't move," he repeated, and it was quite possibly the most impossible thing he could've asked from her, because not a second later, he covered her with his mouth, and it was all she could do to keep her body from convulsing right there and then.

He teased her sensitive bud with the tip of his tongue, and her eyes closed as she forced herself to stay still as he continued to taste her. His mouth and tongue were everywhere; nipping, licking, probing, intense shots of pleasure shooting up her spine. His hands were holding on to her hips, keeping her in place, and that was her one saving grace as he curled his tongue around her clit, flicking the tip over it repeatedly.

The second her body refused to obey her and she arched against him, he pulled away, his eyes glinting with mischief. "Ah, ah, ah. I said no moving."

She was ready to kill him. Ignoring his words, she laced her fingers through his graying hair, grabbing on tightly, desperately trying to force him back again. "Gil, I swear to God, if you don't finish what you've started…"

His mouth back on her cut her off, and she cried out his name in surprise. Her moans seemed to urge him on, his ministrations becoming even more powerful as he pressed his tongue hard against her. He caught her clit lightly between his teeth, flicking his tongue back and forth over it. Small tremors ran through her body, as the need for release continued to build inside of her. She could feel her orgasm looming just in front of her, and moments later she cried out as waves of pleasure took over completely, her hips bucking uncontrollably against him.

He continued his soft nips as her breath came out in short pants above him, slowly bringing her down from her high. When she finally stopped trembling, he pressed his lips lovingly against the inside of her thigh before letting her legs come to rest around his waist.

He kissed his way up her body, tasting the fine sheen of salty sweat that covered her smooth, freckled skin. She sighed against him when his lips finally reached hers, allowing them their first, gentle kiss. Running her tongue over that bottom lip she loved so much, she could taste herself on him, and it never failed to surprise her how incredibly erotic she found that. Her taste on him served as a reminder of what he had just done, and she could feel the arousal build inside of her again at the mere thought.

She rested her forehead against his, as his hands came up to tangle in her long, soft curls. Then he closed the short distance between them and pressed his mouth against hers in a sweet, sensual kiss, and her eyes fell closed as she gave herself completely to feeling of him. He ran his tongue slowly over her lips, encouraging her to allow him entrance, and with a sigh she complied, their mouths fusing together, their tongues battling fiercely for control.

She broke the kiss, struggling for air as he nuzzled his way down to her throat. His rough beard tickled her skin, her senses working on overload. She could no longer tell the difference between her body's reactions to the air-conditioning being out and the heat he was creating by just touching her. All she knew was that his lips against her were incredible, his ragged breath making her tingle all over.

"Thank you," she breathed out.

"You lasted longer than I thought you would," he murmured into her ear.

"And you're overdressed," was her simple reply.

Hooking her feet behind him, she used them to push him up against her, feeling his obvious arousal hard against the inside of her thigh. Reaching down between them, she quickly unbuttoned his khakis with skilled hands, hooking her thumbs on the inside of his boxers, pushing everything down all at once.

Once again she felt the need to giggle; there he was, standing in front of her, pants around his ankles, his erection straining against her, yet still fully clothed above the waistline. But her giggle caught in her throat as she met the intensity of his dark blue gaze. She loved it when he looked at her like that; the look that said he wanted to devour her, yet his love and devotion to her never ceased to shine through.

She grasped him in her hand, stroking him slowly with firm, hard strokes, watching him intently as he bit down on his lip. His eyes darkened further as her strokes grew harder, and she positively beamed as he jerked against her touch.

Grabbing the collar of his shirt with her free hand, she roughly yanked him to her, confidently guiding him to her waiting center. Tilting her head up, she captured his lips in a searing kiss, before digging her feet into his back, pushing him towards her. In one smooth motion, he was buried inside of her, filling her, and neither could help shuddering as jolts of sheer electricity shot through their systems.

They stayed completely still for several moments, letting their bodies adjust to each other, simply reveling in the feeling of being joined in the most intimate way. His hands moved over her back, kneading her flesh with his fingers, finally coming to rest on her behind.

She gasped into his mouth as he drew out almost completely, teasing her entrance, before sliding all the way into her again. He was still holding onto her, making it impossible for her to meet his thrusts, but somehow that only served to turn her on even more. She could feel him pulsating inside of her, throbbing, and she clenched her inner muscles around him, making him groan into their kiss.

The giggle finally escaped her, as she put her hands against his chest and playfully shoved him away, making him slip out of her in the process. She immediately mourned the loss of him inside of her, but smiled at his confused face, knowing he'd soon be back where he belonged.

Hopping off of the desk, she turned around, placing her palms firmly against the cool surface, wiggling her ass at him just a little bit. She threw a look over her shoulder, giving him a seductive grin, only to find him staring at her rear end. She smiled at the completely raptured look on his face; he always did have a thing for her behind.

He raised his hand and caressed her firm buttocks, eyes still unwaveringly locked in place. His touch was tender and loving, yet determined in its path. He kneeled behind her, planting a soft kiss on her left cheek, and she shivered with pure unadulterated desire. She could still feel the sensations of him moving inside of her, yet her entire body hungered for him.

Before she knew it, he'd sunken his teeth into her tender flesh.

"What the-!" She turned her head again, giving him an incredulous look. "Gil Grissom! Did you just bite my ass?!" She couldn't stop laughing; the laughter bubbled up from deep within her until her eyes filled with happy tears.

Gil Grissom had just bitten her tush.

The man would never stop surprising her.

- - - -

It had been there; ripe, full, soft, firm, and oh-so inviting.

He did have a thing for her behind ­ or tush, as he liked to refer to it. He loved watching her in those tight jeans of hers that seemed to accentuate every delicious curve of her nicely shaped bottom. He loved it even more when it was completely bare in front of him.

Bare, inviting, and completely irresistible.

He stole a glance at her face as tears sprung to her eyes from her rich laughter, a sound he cherished almost as much as his current view. He let his hands run down the sides of her thighs, feeling her body tremble underneath his touch. Sliding them up again until they rested on her hips, he stood up as he did, nudging her legs apart with his knee.

As suddenly as he had taken his taste of her, he entered her again with one hard, long stroke, and her laughter quickly turned into deep moans. Each stroke brought him deeper inside of her, and judging by the sounds that were escaping her, he was doing something very right for both of them.

He massaged her hips with his hands, moving to her lower back, her ass. He couldn't stop touching her; he couldn't get enough of her. Her soft pants urged him on, the sound of his name on her lips, and he drove into her even harder, faster, feeling her inner muscles tighten repeatedly around him. She arched her back further for him, her underarms hitting the desk, her forehead coming down to rest against them. The new angle brought him even deeper; he was completely sheeted by her, and he still couldn't get enough.

Caressing her stomach, he moved up to weigh her breasts in his palms, fondling her stiff nipples with his fingers. He pushed her up until her naked back was resting against his still fully clad chest, one hand leaving her breasts to cup her cheek, turning her head to allow her lips to meet with his. He plunged his tongue into her waiting mouth, strangling her surprised gasp. Her arm snaked around his neck, her fingers threading through the soft hair at the nape of it, as he continued to thrust himself into her.

"God Cath," he breathed heavily as they broke away from each other for air, "I can't get enough of you." Her eyes told him everything he needed to know. "I need to be closer to you."

He pulled out of her, briskly turning her around, propping her up on the desk again. Entering her, he hooked her legs around his waist, bringing her as close to him as humanly possible. "Hold on," he grunted into her ear, and she nodded, her arms once again coming up around his neck, holding on tightly.

His hands grabbed her ass, lifting her up against him. Pants still around his ankles, he stumbled forward, almost tripping over her discarded bra in the process, until her back slammed into the flat surface of his securely locked office door.

She giggled into his ear, sending shivers down his spine. "I really hope no one will come knocking on your door."

"It's too hot to even move an inch," he said. "No one will come."

She raised an eyebrow at him. "Oh, I wouldn't be so fast to say that if I were you," she murmured, picking up on his words, using her legs to push herself up and down his length to further prove her point. "And I do believe we're definitely moving more than an inch here…"

He groaned and shook his head at her bad pun, but truth to be told, he loved her smartass comments. A sweet and completely innocent smile adorned her face as her body stilled, but mirth gleamed in her bright blue eyes. Small pearls of sweat were finding their way down between her breasts; her hair lay in big curls framing her gorgeous face, a stray strand stubbornly stuck on her forehead, and he was once again struck by the thought that she was the most beautiful thing he'd ever witnessed.

And so he told her.

If he hadn't known better, he would've sworn that his comment made her blush, as she let her gaze fall down to his chest where she was fingering the top button of his shirt. Then she looked up again, determination shining in her eyes. "And you're still overdressed," she admonished him for the second time that evening.

He watched as nimble fingers started working on his shirt buttons, and still holding onto her securely, her back supported by the door, he began pushing into her again. Inch by inch, little by little, and apparently at a much too agonizingly slow pace for her liking. Biting down on her lip, eyes falling shut, her fingers suddenly lost their gracefulness when she instead grabbed hold of each lapel, ripping it open, the remaining buttons flying all over the office floor.

"Impatient much?" he smirked, and she glared at him.

"Shut up."

He could feel her trying to force herself down onto him fully, but his firm hold kept her from succeeding. He must've been crazy to do so; he wanted it as badly as she did, but the self-torturing part of him held back. She felt so incredibly good; the way her inner walls were squeezing the tip of his member almost brought him over the edge alone. Her soft breasts were pushed up against his now exposed chest, creating the most amazingly torturous friction. He was so damn close he knew he'd find his release immediately if he let her have her way. Not a completely unpleasant thought, but he desperately wanted to prolong the pleasure for both of them. And so he held back for all he was worth.

Her head fell forward, and she almost sobbed out in frustration. "God, you're killing me…" She turned, kissing his neck, his shoulder, his chest, his chin; she kissed him anywhere she could reach, until finally meeting his eagerly waiting lips.

That's when he finally surrendered to his own needs and buried himself completely inside of her, feeling her wet tightness surround him. Over and over, he pushed into her, their lips fused together, tongues dueling brutally, mimicking the motions of their lower bodies.

He broke away from her, attacking her neck with his mouth as she threw her head back, banging it harshly into the door. He latched onto her delicious skin, sucking, licking, biting. He was nothing other than pure branding her, and while he knew that she would kick his ass for it later ­ something he was sure he wouldn't really mind ­ he couldn't have cared less. In fact, neither did she, judging by the encouraging noises she was producing. It seemed to spur her on, as she once again tightened her legs around him, using the leverage to meet him thrust by thrust as he pumped into her.

Before long, he could feel the familiar pressure build up inside of him, his blood racing through his veins, and he moved even faster, desperate to bring her there with him. He knew she wasn't far behind, her own thrusts no longer meeting him in perfection. She was moaning into his ear, her hands clutching to the back of his shirt, her sharp nails digging deep into his skin.

Suddenly she spasmed around him, and he swallowed her screams as her climax hit her hard. Mere seconds later he joined her, the power of her orgasm trigging his own. His vision turned black, his legs buckling underneath him, and they fell to the floor, their entangled bodies still shaking from the power that had surged through them both.

They laid still for what seemed like hours, their breathing slowly catching up with them. His arms were wound around her waist, holding on tight; he knew they should get up, but part of him wanted to stay in this moment forever, still buried inside of her, her petite body sprawled on top of his. Her fingers were playing over his chest, drawing small, invisible patterns, and her mere touch made his spent body shiver again.

He raised his head slightly to find her grinning at him, her chin resting against his chest.

"Hey," she smiled, pressing a tiny kiss to his collarbone.

"Hey you, too." He returned her smile.

All of a sudden her drawing fingers came to a halt, and she looked at him as if a thought had suddenly struck her. "I thought you said we'd never do it at the lab." It was a statement, not a question, but he didn't miss the challenge in it, nor her faked ­ though very much endearing ­ tone of surprise.

"Can't a man change his mind?" he grumbled jokingly, already knowing she had him right where she wanted him.

"I thought that was a woman's right," came her sweet reply.

He could positively see her biting her cheek to keep herself from laughing at him and his complete failure to keep himself from giving in to her earlier seduction.

Ignoring her words, he kept going. "And technically we're not IN the actual lab. We're in my office."

She shook her head and laughed at his answer. "You're reaching, dear." And with that she gave him a quick kiss on the lips before pushing herself off of him. He groaned as he slipped out of her when she stood up, immediately missing the heat that had surrounded him only seconds earlier.

Sitting up, he watched as she walked over to his desk, swaying her hips for him, her lean back still bare for his view. He stood up, pulling up his khakis and then went to work on his shirt, as she bent down, picking up her tossed away bra from the floor. She gave it a quick glance and then turned, giving him an unbelieving look.

"You broke my bra!" she exclaimed.

"Yeah, well, I don't see my shirt looking all that whole either," he returned, trying to sound as serious as possible, indicating the fact that his now only half-buttoned shirt was mysteriously missing three buttons. "In fact, I seem to recall a certain someone ripping it open."

And there it was again; that laugh that seemed to find its way to his very core. He'd quickly found that making her laugh was one of the things he loved the most. Even when things seemed dark and without hope, her laugh would give him that spark of light and life that he needed. He wanted to make her laugh for the rest of her life.

"Touché," she finally said through her giggles, wiping at her eyes, and he winked at her.

She pulled her halterneck top up to cover her braless chest, tying it around her neck, before smoothing down her skirt. Stepping up to him, she put the bra in one of his pockets. When he looked at her questioningly, she simply said, "Don't want the cleaners to find it in your waste basket, now do we? Besides," she added with a beaming smile, "you might wanna keep it as a souvenir."

He fingered the material in his pocket as she unlocked his office door. Oh yeah, he'd keep it, alright. Before opening the door, she turned back to him, looking at his hand.

"Maybe you want to frame it, too?" she asked innocently.

He rolled his eyes at her, but couldn't keep himself from laughing at her expression. "Don't push it."

Once again, she shook her head, and a small giggle escaped her. "Well, you better hope I have an extra bra in my locker," she said as she pushed the door open and stepped out into the corridor with him following right behind in her tracks.

Looking around to make sure no one was watching, he placed his hand on her waist, leaned over her small frame and whispered into her ear, "To be completely honest… I think I prefer you out of it."

He felt her tremble, and then she turned her gaze to him, her eyes glazed over with new-found desire. "Race you to the locker room."

They rushed through the lab corridors, hoping to avoid the curious eyes of their team members, trying to stay invisible as they made the inevitable walk past the break room.

No such luck.

"Hey guys!"

Physically reaching up to cover their faces in childlike gestures, they tried to ignore the voice that seeped out to them, but it was all in vain.

"Hey guys! Wait!"

They both stopped and spun around at the same time, polite smiles plastered on their faces, but if looks could kill, the fervently waving Greg would have dropped dead right there and then. Completely oblivious to their deadly stares, he kept going.

"You guys finished with the reports?"

Judging by the mess on the table in the middle of the room, the rest of the graveyard shift team had obviously done their part in defying the heat ­ and ignoring work ­ as well. They were all comfortably leaning back into their chairs around the table, poker cards in their hands, a stack of change piled up in the middle. At the moment, though, all eyes were for some reason focused on them.

"Um… yeah," Gil got out at last, when he realized that Catherine's eyes were also on him, a knowing smirk on her lips. Her hand, hidden from their view behind him, came up to teasingly caress his back, and he threw out a quick white lie, realizing he needed to get her out of this room as soon as possible. "We're just gonna go get something to eat."

They all seemed to accept his answer as they returned to their cards, Sara giving them a, "Bring us back something, will ya? We're starving here."

Thinking they were off the hook, the pair turned to leave, but Nick's voice stopped them once again.

"Hey Cath, what's that on your neck?"

Her hand flew up to just above her shoulder blade, where she could still feel her lover's lips marking her. She gave him a nasty glare before changing her expression completely, smiling sweetly at Nick, racking her brain for a plausible answer.

"Heat rash."

The others raised their eyebrows at her, while Gil bit his cheek hard, trying to hold his laughter back. She looked adorable trying to explain herself, and he'd be lying himself blue if he were to say he wasn't enjoying every second of it. He had to give it to her, though; it was a reasonable explanation, and he almost would've believed her had he not been the one to give her the `heat rash' in question to begin with.

"Grissom's office is hot as hell," she quickly added with an innocent shrug of her shoulders. "You have it good in here, you know. Now, if we're done here, we'd like to get something to eat. Later, guys." And with that she grabbed the side of Gil's shirt and dragged him out, leaving the rest of them behind before they could object.

The younger CSIs sat back and simply looked at each other, cards suddenly forgotten.

"Was Cath not wearing a bra?" Greg finally said, voicing what they'd all been thinking, and the others nodded in agreement.

"Yeah," Nick chimed in, "and Grissom's shirt was definitely missing a button or two."

"Heat rash…" Warrick muttered, but couldn't hide the grin that was slowly creeping up on his face. He looked at his friends and then finished with a wink, "Heat rash, my ass."

A second later they all broke out in hysterical laughter; laughter which carried its way through the lab until it reached Gil and Catherine standing right outside the door to the locker room.

With one hand on the door handle, he turned to her, a slightly worried look on his face. "Think they know?"

She simply smiled, pushing his hand down and pulling him into the locker room with her, and all his worries instantly disappeared.

The door closed behind them, the lock turning with a loud click.

FINIS
