Steam swirled around them, encasing them in a fog of heat and sweat. The water sloshed loudly against the side of the tub, limbs frantic, pulling skin tight against skin. The searing mouth latched itself to Nick's neck, sucking, nibbling, marking, leaving the flesh red and raw. He gripped strong hips tighter, delighting in the familiar texture beneath his fingers.

Cocks brushed together, slowly, lusciously, water slapping lewdly against their writhing bodies. The hot mouth moved lower, closing over a nipple and Nick gasped loudly, pushing his hips up and letting his head fall back against the edge of the tub. He felt the wicked smile against his skin, but then all he could feel was the warm, wet hand slowly stroking him and he had forgotten how good baths could be.

And there wasn't enough room in the tub for what they wanted, what they needed, but nothing was going to stop them from trying. Legs were awkwardly wrapped around each other, lips and tongues clashing with teeth and moans, water splashing out of the sides of the tub, and maybe Nick would have cared, but there were two fingers pressing against his opening and water on the floor was the last thing on his mind.

He tried to move, tried to lift his hips higher, get those fingers deeper but there wasn't enough room, he kept running into muscle and skin and heat, losing his concentration. He just needed a little more, he was close. His hips fought his brain, wanting to go both up and down at once. He let his eyes drift closed, letting the familiar feeling building at the base of his spine wash over his whole body.

"Greg…" he let slip from his mouth, head thrashing from side to side, hips bucking, sending water flying.

"I need to come home early more often."

Nick's eyes snapped open and he sprung back in shock, the bath suddenly very cold. "Jesus, fuck! Greg, what the hell?" Nick was panting heavily, slightly more to do with the shock of getting caught than what he was getting caught doing. "Aren't you supposed to be in New York?"

"Aren't you supposed to wait until I get home before you start masturbating?"

Greg was standing in the doorway to the bathroom, looking slightly rumpled as if he had just spent a few hours on a plane, which Nick assumed he had, but smiling that wondrously smutty smile that wasn't helping Nick's predicament.

Nick, blushing, began laughing at himself. Shit, his fantasies could get out of hand sometimes…or more accurately into his own hands. He leaned back in the tub again, feeling the muscles relax in his back once more. He was stuck somewhere between thorough embarrassment and impending orgasm and his brain couldn't agree with his body on the subject. "Fuck," he whispered.

"We could start there, sure," said Greg, stripping off his shirt, and quickly moving along to his pants.

"What are you doing?"

"You don't get to be all hot and wet and naked without me," he said, removing his socks and tossing his boxers onto the floor, ignoring the large puddles of water that had formed around the tub. He kneeled down next to the bathtub, tracing his fingers along Nick's arm.

"You aren't mad?"

"Too pretty," said Greg, shaking his head and leaning in for a smoldering kiss. "Besides, I like watching you do dirty, dirty things to yourself." He let his hand dip beneath the water, rubbing circles into Nick's abdomen.

Nick let out a soft sigh, leaning forward to capture Greg's mouth with his again. "Not enough room," he murmured against soft lips.

"What?" replied Greg, not expecting those words to come out of Nick's mouth.

"Not enough room in the tub for you to fuck me."

"I don't want to know how you know, but is there enough room in the shower?" asked Greg, that wicked smile on his lips again. He stood up and went towards the far end of the tub, near Nick's feet and opened the tub to let it drain, and running water, making sure it was the right temperature before he turned it on full blast.

"Do I ever tell you how smart you are?" asked Nick, rising up out of the water on slightly shaky legs, and damnit, if he didn't look edible. Water highlighted every muscle, every curve of tender flesh and Greg thinks for a moment he might pass out before he gets a chance to touch.

"Not nearly enough," he finally manages, turning on the shower head and stepping into the tub, bringing the shower curtain shut behind him. Greg never thought he'd be so thankful for the brand-new shower head Nick made them buy, but he can't help but bless it's presence as Nick pulls it down from it's perch and runs it slowly over and across Greg's body, the water lightly massaging tense muscles and awakening others.

Nick's free hand was lazily running over Greg's cock and his tongue tracing patterns on his neck. He sighed into the soft skin, taking in the scent of Greg and fresh, clean water. He'd been aching so badly for Greg, that he'd actually wrenched his back a bit at work. So he'd come home and drew himself a hot, relaxing bath, but obviously, it took more than that to get his mind off of Greg.

Not that it really mattered now. Because somehow, Greg had gotten a hold of the showerhead and put it back, and Nick was up against the tile, Greg at his back, slowly working two fingers into him and running light kisses along his shoulders. Nick moaned loudly, pushing himself back onto Greg's fingers, wanting more.

"This what you wanted?" panted Greg, nibbling on Nick's earlobe. "This what you thought about while you fucked yourself?"

"Yes," moaned Nick, lying his cheek against the cool tile.

"What do you want now?" asked Greg, letting his fingers slid out of Nick.

"Fuck me."

"Can't hear you, baby. Tell me what you want."

"Make me come, Greg. Fuck me ‘til I come."

Greg let out a slow sigh into Nick's neck, before leaving Nick's warmth and dashing out of the shower to grab a condom from the medicine cabinet. He shakily tore off the wrapper and rolled the condom on before returning to the shower, cupping Nick's ass in his hands and placing more kisses on the backs of Nick's shoulders.

He let out a soft groan as Nick pushed back into his touch, overcome by the heat of his body and he couldn't wait another second. He grasped his cock and moved it, positioning the head at Nick's opening, beginning the slow, languid press that always left him with shortened breath and blurred vision.

But even through his blurred vision he could see Nick smiling now, could hear the light sigh that escaped his mouth as Greg finally pushed all the way inside of him.

And Nick loves this, more than he's ever willing to admit, loves feeling Greg every way he can. Deep inside of him, hot breath on his neck, grasping hands on his hips, soft thighs against his own. He grasped for purchase on the slick tile, but finding none, settled for reaching one hand behind him, grabbing at Greg's side, pulling him closer, deeper.

They rocked together fast, neither one left with any self control, and the steam rose around them, only this time it wasn't in Nick's head, it was real and that was Greg's cock brushing against his prostate and Nick can't hold back a long, low moan as he comes, clenching tight around Greg.

And Nick can feel Greg collapse against his back, feel the hot moan across his back, feel Greg buck into him, feel his orgasm race through his body, over, but Nick was too dizzy to do much more than lean against the tile, letting the last of his release wash over him. It takes a few minutes before Nick returns to full lucidity, Greg's already tossed the condom and Nick is leaning with his back against the tile now, watching Greg and letting his breathing slow.

And he could see the sleep edging its way into Greg's expression and he pulled him into his arms, placing a soft kiss on his neck. "Let's go to bed, I'll give you a real shower later."

Greg sighed happily, turning slightly to turn off the water. He wondered slightly how much they had wasted that day, but then placated himself by resolving that they would just take showers together until they made up the difference. Still slightly high on endorphins they toweled each other dry, exchanging quick kisses and giggles, relearning each other's bodies.

They finally stumbled to the bed, neither one bothering with clothing as the burrowed under the covers, huddling together as they tried to regain the lost warmth of the steaming shower.

"You're all pruny," said Greg, kissing Nick's fingers as they lay in bed.

"Well, I did spend a much longer time in the bathroom than I planned."

Greg was laughing softly now. "I can't believe I caught you masturbating."

"Shut up."

"No, I think it's sweet that you can't go for more than a day and a half without me. You should have called for phone sex," Greg said, laying his head in the crook of Nick's shoulder, his voice softening, feeling the pull of sleep.

"You were supposed to be at a conference, not here to catch me in the tub. And by the way, why are you home early?"

"Grissom said he was going to be really short-handed tonight and he needed me to come back if I wasn't missing something desperately important. I wasn't…well, except for you masturbating in the tub."

"Shut up," chided Nick, tightening his grip on Greg as he slipped towards sleep.

"Nothing wrong or dirty about it. It's totally natural," sighed Greg, eyes closing as he drifted off to sleep. "Fuck, I did it in the hotel room last night."




Fin!
