Summary: PWP, Grissom realizes what he wants and goes after it.

Greg was startled to find his boss, Gil Grissom, on his doorstep. He hadn't even realized that the man knew where he lived. So he stood agape, the early morning breeze ruffling his hair and chilling his bare chest and feet.

"May I come in, or is this a bad time?" Gris asked after a long, awkward pause.

This snapped the younger man out of his stupor.

"Oh. Yeah, sure. Of course you want to come in. That's why you're standing there, right?" he stammered. *Idiot!* he thought. *Could you be any more of a dork?*

Greg moved aside, and Gil strode through the door. As crime scene investigators are wont to do, he noticed all the details of the modesly furnished apartment, trying to discern more about its occupant. Then he turned to the young chemist.

"I've been thinking a lot about this, Greg. For several months. I've finally realized why you're always so flustered around me."

"Flustered?" the half-naked man squeaked, a red tinge creeping up his cheeks.

"Yes. And there's only one thing to do about it."

"Um, ‘it?'" Greg inquired. "What, exactly, is ‘it?'"

"Lust," the older man stated matter-of-factly.

A small gasp escaped the spikey-haired young man as his jaw dropped and his eyes grew wide.

"I'm n—"

His denial was quickly cut short as Gil's warm lips met his in a short but promising kiss.

Gil wasn't the only one with powers of observation. When they broke their kiss, Greg noticed the other man's pupils were dilated and growing larger by the second. This made the corner of his mouth quirk up in a lopsided smile, a smile that was returned by the older man.

This time he was prepared when Gris moved toward him, and he moved, too. They stood in the middle of the living room, door wide open as the sun was cresting, and kissed lustily, mouths open, tongues wrestling. They groped each other with fervor, and Greg released a loud moan when he felt Gil's hand slide over his ass.

"I always knew you'd be a noisy lover," the taller man whispered against his soon-to-be lover's neck. This unleashed another, louder cry of passion.

"And I always knew you weren't as straight as everyone said," Greg moaned throatily, his head still thrown back in passion.

He felt his boss pull away from their amorous encounter mentally, before he pulled away physically.

It felt like a bucket of cold water had been thrown upon them both.

At that moment, Grissom's pager went off.

"I've got to go back to the office for awhile," the other man stated hastily, without a glance at the page.

As quickly as he'd entered the upstairs apartment, he exited, leaving Greg hard, horny, and alone. The young man stood before his open door for several minutes, his mind a jumble of feelings: desire, embarrassment, bereavement, and exasperation. He closed the door, then leaned back upon it, closed his eyes, and tried to get his breathing under control.

*How did Gil know I've wanted to jump his bones since forever?* he pondered. *And why did I have to say something stupid about which team he batted for? Idiot! He was right where I've always wanted him!*

"But then I had to open my big mouth!" he berated himself aloud. "And I'll never get this chance again. He couldn't make up an excuse fast enough. Pager? Yeah, right."

He slumped down on his couch and pouted for a good half an hour. Finally, he stood, shucked his jeans and resignedly crawled into bed alone to sleep the sleep of the depressed.

A loud knocking pulled him from the edge of sleep where he'd been hovering. *Great! I supposed that's someone else waiting to humiliate the shit outta me!* he thought as he stomped to the door.

He flung open the doorway and froze. There was Gil Grissom.

"I didn't think you'd…" Greg began.

"Don't talk," Gil ordered as he closed the door behind him.

Predatorily, he advanced toward the younger man, backing him up. He didn't stop until his prey's back hit the doorframe to the bedroom. Then he pounced.

Gil wasted no time in attacking Greg's mouth with deep, wet kisses. His hands were everywhere at once, petting, tweaking, and teasing. The passion they had built earlier picked right back up where they'd left off. Then the older man took it to the next level.

He nibbled and licked his way down the other's neck; he sucked and bit across his chest, stopping only briefly to stimulate each nipple with his tongue. Then he dropped completely to his knees in front of the bulge in Greg's white boxer briefs. Through the knit fabric, he lightly scraped his lower teeth across the base of the fully aroused cock.

Greg had been trying to stay silent for fear he would send this man on his way once again. But he failed. When he felt the heat of Grissom's mouth near his balls, he loosed a low, sultry growl of pleasure.

Before he had a chance to censor or reprimand himself, he felt his underwear being tugged swiftly down his legs. His penis was immediately engulfed in the hot wet cavern of the gray-haired man's hungry mouth. As he was being sucked rapidly toward completion, he felt a sly finger toy with his velvet sacs before snaking its way to the cleft in his ass. Gil teased his opening with a spit-wet finger for only a few seconds before slipping it inside the hole.

Greg spread his legs even wider as he screamed in fulfilled pleasure. But before he had a chance to register a coherent thought, he was pushed into the bedroom and toward the bed. Gil shoved him hard onto the mattress. He was about to protest the aggressive treatment when he turned his head and saw his lover; Gil was panting with desire.

The older man opened the top drawer of the night stand with confidence, knowing he would find lube there, and he did, dropping it beside Greg. Then, without breaking eye contact with the younger man, he ripped his shirt open and off with one frenetic movement. He dropped his pants to the floor, kicking them off as he toed off his shoes. Hurriedly, he dropped his boxers and climbed onto the queen-sized bed.

He went straight to work, positioning Greg the way he wanted him: on his elbows and knees, ass in the air. He inserted a well-lubricated finger back into the chemist's asshole, working quickly to stretch the opening. A second finger was soon added, and then a third. His young lover squirmed and moaned with building desire the entire time. Greg wondered only briefly where the condom had come from when he heard the tearing of the wrapper, but that train of thought was quickly derailed when he felt Gil slide his latex-sheathed cock inside him.

Greg pushed back almost immediately. Gil needed no further encouragement and began fucking him hard and fast. He had a firm grasp of Greg's hips as he plunged deeply inside. With each stroke Greg cried out in ecstasy, becoming louder and more vocal as he neared gratification.

He screamed when he came, but it was sufficiently muffled by the pillows so as not to disturb the neighbors. Gil was still pounding away inside him, and it wasn't until the younger man had nearly caught his breath that he heard the older man groan and shudder.

They stayed frozen in position for several long minutes as their heart rates slowed to normal. Only then did Gil allow himself to relax down onto the wild-haired man's bed. Greg fell over onto his side, facing the other, and smiled expectantly, but hesitantly.

"I apologize for leaving earlier," Gil began. "You touched a nerve. I tend not to give in to my, well, my baser instincts. People think I'm strange enough already."

"Without adding being gay to the mix," Greg finished.

"I supposed so."

"So then why did you come back?" he queried.

"I figured a man my age should stop worrying about what people think of me. Bug Guy. Gay Guy. It really doesn't matter any more," Grissom answered.

"It never did."

"Plus, you moan really well," the CSI teased. "I always knew you'd be vocal in bed."

"You ain't heard nothin' yet," the younger man replied with a seductive smile.
