Grissom had said that, when he left CSI, it would be 'poof, gone' like the ghost he'd been at high school. The truth was a little different. The operation to correct his hearing condition had not been a success. In fact, it had made things worse and, although he still had some hearing in each ear, he was now legally deaf. What he could hear was nothing like enough to let him continue working as a CSI and no one harboured any illusions about his suitability to act as an administrator. So, he was leaving.

It had taken six trips to his office, so far. There were racing cockroaches to collect, and things to be sent forward. Some of his materials were to be sent to other researchers in the field, some were to be sorted and put into order so his erstwhile colleagues would still have the resources they needed to do all but the most complex insect timelines without outside help, and some were going with Grissom.

Just as he was coming back to his office for the last time, to check he had everything, before trying to slip away quietly and without a fuss something caught his eye. He still had the ingrained reflexes of an investigator so he quickly pinned down what it was. One of the small labs had blinds over its windows and those blinds were down. Nothing particularly unusual there, but what was unusual was he was sure he'd seen the blinds distort as if something had pressed up against them briefly. Curious, he went to investigate.

Fifteen minutes earlier, inside the room, completely unaware of anything else, Catherine and Sara were, as young lovers often are, lost in the sensation of holding and kissing their beloved. Ever since that drink in the bar a few weeks ago the resentment and hostility between them had drifted away and been replaced with an understanding that they were both attracted to the other, an attraction that they were starting to explore.

Feeling brave Sara started to undo Catherine's blouse. Although they'd explored under each other's tops with hands before, and neither of them was particularly bashful this was still the first time either of them had gone this far. She could tell by the hitch in Catherine's breathing that this step forward was welcome, and that the redhead was enjoying the sensation of being revealed as much as Sara was enjoying seeing her love's torso exposed. Of course it wasn't just being exposed to the eyes, but explored with fingertips, lips and tongue as well. Sara was willing to take forever prolonging this experience, and Catherine was enjoying the sensation of someone *wanting* to take their time to see her naked rather than wanting everything off as quickly as possible. And yet, Catherine wanted to see Sara naked as well. She reached out and far more quickly undid the buttons on Sara's blouse, at least in part because her own torso was still being held, touched and kissed and she couldn't return the favour without some major reorganisation. A large bed would have been much more ideal than a small lab at CSI but whatever, Catherine was just keen to get a look at her new love. Once the last button had given way she moved slightly, trying to pull the blouse off Sara, and for the first time got a proper look at that long slender torso. Sara had come in without a bra today, a fact that made Catherine gasp because it was so unexpected, but also because it allowed her to see just how tight and swollen her love's nipples were with this exploration.

Catherine reached out to take Sara's breasts in her hands. Sara gasped at the contact and pulled back slightly, looking up at Catherine's face with eyes darkened almost black by lust. Sara pushed herself forward into the contact, through the contact, moving up to kiss Catherine's mouth once more. Her agile fingers continued, much faster now, to undo Catherine's top as their tongues entwined in that increasingly familiar rhythm and Catherine started to run her hands over Sara's torso, returning every few moments to cup her breasts and fondle her nipples.

Soon the pair of them were topless before each other, devouring the sight briefly with their eyes. Then, Sara made a bee-line for Catherine's nipples with her mouth. Catherine lay back, enjoying the sensations again for a while, before pushing Sara off her and back into the window so she could return the compliment. This had the desired effect of getting Sara onto her feet so that Catherine could undo her trousers and take them down, but the entirely unexpected consequence of alerting Gil to something unusual happening.

Sara realised her trousers were being undone, and co-operated, pushing them and her pants down as soon as her zipper was far enough down to let her. She bent to remove her shoes and garments whilst Catherine removed her own lower garments equally hastily.

The pair were at their most vulnerable when Gil cracked the door quietly to see what was happening, not wanting to disturb whoever was working inside. Sara was still bent over, presenting a wonderful view of her legs and ass to the door, whilst Catherine was crouched in a more inelegant pose, standing on one leg with the other foot on the rung of a stool so she could work on her shoe. Those years of work as a stripper enabled her to look natural doing this, and she was also displaying her whole body towards Sara to the best effect, and inadvertently towards the door too.

Grissom stopped, shocked beyond thought and unable to tear his gaze away from the sight before him. He might remain detached and uninvolved when working, but he still appreciated female beauty. Here, right in front of his eyes, were two of the most beautiful women he knew almost naked and apparently stripping for each other. Part of him knew he should leave, now, before he saw any more or got caught, embarrassing all of them. But the parts of his brain that controlled voluntary movement seemed to be in shock. And so he stood, unmoving, as Sara started to straighten up and took in the sight in front of her eyes, moving forward and placing one hand straight onto Catherine's mound as the other swept round to support her back. He continued to watch as Sara bent her knees, sliding her body down over Catherine's much to their mutual delight. He was stunned as Sara straightened her legs, back muscles straining, as she picked Catherine up. Finally, Catherine completely abandoned all attempts at getting her leg out of her trousers and just wrapped her legs around Sara, pulling herself as close to the brunette as she could. The brunette's journey wasn't far, two steps forward so she could deposit Catherine on the evidence table (which, Gil noticed with some part of his mind, was mercifully clear of evidence). With Catherine sitting on the table, gasping at the cold against her skin, Sara pushed her back, chasing her body down so they were lying on the table, shuffling to get their legs on too, with Sara on top. Now Gil could see down the flanks of both ladies, drinking in the sight of Catherine's breasts again and Sara's for the first time.

There was low, muttered conversation that he couldn't hear, but for the first time ever he didn't really care. His eyes were feasting on the sight before him as the two women continued their encounter: kissing, fondling, holding and stroking each other bringing each other closer and closer to orgasm. Several times, if they had been paying attention to anything further away than arm's reach either of them could have caught him standing there watching. But they were so wrapped up in this first time together that they would probably have missed a bomb going off in the next room, never mind a door that was standing just ajar with a face in the crack.

Gil continued to watch, fantasising that they were putting on this display for him, enjoying the moment and savouring the memories of his last day that this would give him. The placement of hands and legs, the fall of hair and the like was nothing like in the porn that he had watched over the years, where everything was more or less skilfully arranged for the camera's eye, but was all the more potent for that. This display was two beautiful women caught up in their own special moment and it had a power and a feeling that no amount of staged sex could bring.

Suddenly, Grissom realised that the end was nigh. Both women were flushed, finding it difficult to breathe, their bodies starting to move spasmodically, almost out of their control. Mustering all his willpower he stepped back.

He'd got far more than he ever expected from his last trip into the CSI lab, but he would doubtless see these two again. For all their sakes he needed to let them keep their final moments intimate and secret.

As he walked away down the corridor with a smile on his face, back inside the small lab orgasm swept through first one and then the other, leaving them both sated for the moment, but knowing they would do this again. As they lay there, cuddling and basking in their post-orgasmic bliss, Catherine looked at her new lover and smiled.

AN: mrswoman asked if Gil had seen Catherine's breasts before, and when - he sees them earlier on, when she is trying to get her trousers off with one foot on the stool - unless she was contorted in some very weird directions. Of course if you are a Gil/Cath 'shipper as well you might have other ideas, but that was what I meant.
