Summary: A shot request fic for sandersstokeslove. The usual smut that involves glass walls.

Greg sat behind his old desk, the one he had worked so hard to get away from, more pissed off then he could ever remember being in his life. And that was saying something, when you considered all the shit he’d been through. He slowly lifted his left hand to slip a slide under the microscope, the heavy cast on his wrist making the job unnecessarily complicated.

“Damn it!” he shouted as the slide dropped to the table. Greg responded by slamming his wrist into the table then crying out in pain.

“You know, you really shouldn’t do that.”

“Ya think?” Greg snarled at a grinning Warrick who was leaning in the lab’s doorway.

“It’s all your own fault for chasing kittens up trees.”

Greg, childish as ever, blew a raspberry at a laughing Catherine and then turned around to pick up a file, muttering under his breath. Once he had retrieved it from the stack on the desk, he spun back round, flipping it open and scanning the contents before handing it to the giggling pair of CSIs in front of him.

“You got yourselves a match. Now, get the hell out of my lab.” But he was smiling again as he pushed Warrick and Catherine back out into the corridor.

Greg sighed, crossed his arms and wandered back into the lab, making his way to the coffee mug he decided he needed to refill. He picked it up then made his way to the break room. In each lab along the way he watched his busy colleagues.

Henry was explaining something to an exasperated Ecklie, Hodges was sucking up to Grissom as usual and Sara and Bobby were doing something with bullets and ballistics gel that looked like great fun. Greg sighed to himself, wishing he could have been in any of those rooms instead of stuck back in DNA again.

He wandered into the break room and poured out his usual Blue Hawaiian, taking a cookie from the open box on the table on the way back out. He nibbled on it and began to smile, the sugar fix starting to kick in. He finished the cookie and started whistling before stopping abruptly. It suddenly hit him that the only CSI he hadn’t seen on his tour of the lab was Nick. He frowned then set off in search of him.

He walked for what seemed like forever, poking his way into all the labs in his path. Archie had peeked up from his examination of CCTV footage to say he hadn’t seen Nick all night and the techs in the garage were working on a Tahoe for Warrick, but couldn’t remember seeing him. By now he was beginning to worry. According to the reception desk, Nick had signed back in thirty minutes ago and no one had seen him since. He wasn’t in any of the labs and Greg even checked all the bathrooms in desperation but drew a blank.

He sighed and was about to pull out his cell and call Nick when he remembered the layout lab at the back of the building. He quickly finished his coffee, dropping his mug off in the DNA lab before heading to the forgotten room at the back of the building.

Because of the glass walls, he located Nick quickly. He was standing behind an under-lit layout table with pieces of glass strewn all over it. But it wasn’t that that had caught his attention. It was Nick’s trousers.

Greg sucked in a breath and became instantly hard as he watched the delicious scene in front of him. There was Nick with his belt and pants undone. His eyes were closed and one hand was inside his underwear while the other was supporting him on the table. His hand was travelling slowly up and down and his face was flushed a delicate shade of pink. Greg couldn’t tear his eyes away from him.

Without thinking, Greg’s own hand travelled slowly downwards until it had reached his waist. He carefully popped the first two buttons on his pants and slipped a long-fingered hand inside. To start with, he just palmed his straining cock through the thin cotton boxers but as Nick’s movement began to speed up he let his hand travel inside the thin material and wrap around the thick shaft that felt heavy and warm to his touch. He timed his strokes with Nick’s, increasing the speed and strength of grip as the pleasure increased.

This whole thing was so unlike Nick. He didn’t take risks like this in public places. And public places like work? In a lab with glass walls? It was unthinkable. This was more Greg-like behaviour. He had always loved the thrill of possibly being caught, but since when had Nick turned into an exhibitionist?

He continued to jerk off, feeling his body tighten and tingle as his climax drew near. Through the glass wall he saw Nick begin to rock his hips, fucking his hand, as he bit down gently on his lip to stifle a moan. Watching him, Greg knew it wouldn’t be long. He increased his pace and tightened his grip once again, desperate to cum at the same time as his lover.

He couldn’t take his eyes off Nick. He watched, enthralled, as Nick’s hand on the glass table top formed a fist and his movements became more erratic. He saw Nick’s chest heaving with the effort to draw breath and moaned as Nick let his head roll back.

The next thing he knew, Nick’s hips were thrusting forward violently and his hand movements became stuttered. He saw white fluid running down the flesh of Nick’s cock and hand and that was enough to bring Greg shuddering to his own orgasm, slumped against the wall, red in the face, gasping and sticky as he watched Nick clean himself.

A sudden realisation - well, three realisations - struck Greg as he stood there, trying to regain his composure. One – he’d just jerked off in the middle of the fishbowl that was the crime lab and therefore had security cameras everywhere. Two - he had nothing to clean the evidence up with, and three – all Nick had to do was look up and he’d see that Greg had seen the whole thing.

Greg, body still being wracked by post orgasmic tremors and a feeling of euphoria, shuffled down the corridor, a quiet smile on his lips as he replayed what he had just witnessed.

Nick smiled to himself, knowing that Greg had seen it all. If Greg had known Nick had planned it all, it wouldn’t have been nearly as much fun . . .
