~~

They were on one another before the front door closed to. Gil kicked it shut with one foot as he reached for Nick in the same heartbeat.

Nick went to him, mouth first, lips connecting with soft lips, tongue pressing between them to duel sweetly with its counterpart.

Gil hummed softly and Nick growled in response, the sound stroking every nerve in his body. Hands were pulling at his T-shirt, pushing and pulling the material out of the way to get to skin, only steadying once they'd found smooth flesh.

Nick's own hands curled loosely around Gil's throat before he traced one down, along the colour of the black shirt to the first fastened button. One by one they came undone, fingertips teasing smooth skin, light hairs.

They'd been teasing one another for months.

Tonight, everything had escalated.

Nick pulled back a little, tilted his hand, attacked from a different angle. Teeth and lips clashed before they worked it out and the kiss deepened.

Gil's fingers brushed across pebble-hard nipples, thumbs caressing down a firm belly as he dipped into the waistband of Nick's jeans.

Surprised by the sheet need fuelling the encounter, Nick responded in kind, cheating, pressing his palm against Gil's crotch and taking advantage of the lightweight material of his suit pants.

Seeing Grissom in his all-black suit, standing in his office as he'd thrown his jacket casually across the back of his chair and removed his tie. Seeing the momentary expression of heat on his boss' face as he'd stopped at the door and simply watched.

Nick moaned at the recent memory, knowing how it must have looked, how he must have sounded.

"Taking it all off?"

"Only if you want me to."

"Gil." His voice almost broke on the name as his lover's lips sealed on a point between his neck and shoulder, teeth nipping gently. "Gil, Gil, Gil...." A mantra, telling himself this was real. It was happening between them at last.

Those lips tore away from his skin and stormy blue eyes regarded him as strong fingers played in his hair and on his chest.

"Tell me what you want, Nicky."

That nickname would never sound the same again.

"You."

"Me what?"

Lips back at his throat, skipping lightly across his shoulders and back.

"You. I want to know the sounds you make when you're turned on. I want to hear them."

One of Gil's hands was working his zipper now, as that wicked tongue danced along his collarbone.

"I want to make you come, see your face, hear my name on your lips."

He gasped when cool air and hot fingers touched his steel cock. Gil knew just where to touch, how to tease and how to stop him from coming right here.

They hadn't even made it out of the hall. "God... Gil...."

Grasping the other man's hand, Nick stayed it and Gil's head once again lifted from the evidently blissful task of bathing his throat.

Nick caught his breath. Never before had he seen such an expression of desperate lust on anyone's face. No one had ever wanted him so much.

Grissom was losing control. For him. Over him. It gave Nick the mastery of his own arousal and he reached to take Gil's hands into his own.

"Couch," he commanded.

Kicking off their shoes and trousers as they went, they dropped to the leather seat together, mouths once again finding each other, hands fumbling through underwear.

Gil was quickest and his hands on Nick's cock blew all the electrical impulses in Nick's brain to hell for long enough that by the time the younger man remembered to breathe, Gil was kneeling on the floor between his legs, a thoroughly obscene smile shaping his lips.

It took a moment for Nick to realise and then he watched his cock vanish into the wet heat of his lover's throat.

He could only stare as pouted lips drew up along his erection before plunging back down,

His hands clawed at the leather cushions, panic taking him for a moment as he imagined coming in his boss' mouth.

Then blue eyes locked with his own and Gil reached to take up his taut fingers.

Holding on tight, Nick kept his eyes wide open as he rode the incredible sensations spilling through him.

Seeing Gil at his groin, seeing that mouth that he'd watched so often spouting wisdom and nonsense, Nick clung as hard as he could he his shredded control.

But when Gil swallowed around the head of his cock, he screamed, pulsing steadily down his lover's throat until he felt he might just pass out.

His whole body wrung out, Nick watched as Gil stood and directed Nick's hands to his aching testicles.

"Play," he instructed softly, one of his own hands fisting around his thick erection. Nick imagined he could get hard again from the view alone.

Gil Grissom, standing between his spread thighs, feet slightly apart, hand moving back and forth on his own dick. But to be stroking the man's hard thighs as he did himself, to be rolling heavy balls in his palm... this went beyond any fantasy.

"Like to have them sucked, Gil?" Nick asked, voice rough.

Gil's only answer was a strangled groan. His hand sped up.

Nick smiled, holding the hot, blue gaze staring down over him.

"First one, then the other, feel my tongue lapping at them, the suction...."

Gil threw his head back and cried out, meeting Nick's eyes again moments before he came.

Nick wanted to swallow it, like Gil had swallowed him. But he hadn't the strength to move so he watched, admiring the white ribbons, hard again as he felt Gil's cum on his skin.

Gil sank back onto the couch, reached for Nick as his lover reached for him.

They cuddled for a long time, murmuring words of reassurance only they would ever hear.

Later, still sitting together as the sun rose in the sky outside, Gil settled his head on Nick's shoulder and closed his eyes.

"I want you to make love to me," he murmured, feeling fingers in his hair, a kiss at his temple.

"I will," Nick replied softly. "For a long, long time."

Gil considered that. "And tomorrow?"

A smirk crossed Nick's face. "We'll do it all over again."
