"Ow, ow." Gil tried to move off his knees but they were hurting and stiff and he couldn't lever himself up. So he sat back on his legs and that afforded him some relief.

He knew what his problem was - he was getting older and despite the dry desert heat that was supposed to hold the aging process at bay, his knees were becoming arthritic. And, he supposed, whose fault was that?

Oh yes - Nicholas Stokes - that's where the blame lay.

There was no doubt about it, Gil Grissom's days searching around for evidence while on his knees were numbered, he could still crouch quite well, so that wasn't such a problem. He'd have to remember to keep off his knees at scenes, because rising to his feet was hardly what he would call an attractive manoeuvre and he'd probably have to call on help to accomplish an upright position.

There were things he could do about it. He supposed he should start with a physical with his doctor - but he was fairly certain of his self diagnosis. There were other things he could do to help - he'd 'Google' it, but he was sure Cod Liver oil was a natural remedy. He already took a capsule a day, but it wasn't anywhere near the maximum strength he could have each day. There was also Chondroitin Glucosamine; he'd read an article about that some time ago and it was, apparently, medically proven to alleviate arthritic joint pain. He'd start with his doctor though.

He was lost in this reverie when a very familiar gravelly toned voice interrupted his thoughts.

"Now just what are y'thinkin' 'bout, it ain't me is it and I'm sorta thinkin' that given the circumstances y'should be!"

Gil grinned at Nick who had slid down the wall and was facing him - obviously returned to the land of the living from his post orgasmic bliss. Nick had wonderfully intense orgasms, and Gil did take it as a compliment that he could induce an almost stupor like state in Nick.

They been out to a movie and all the way home while Gil was driving, Nick had been touching and teasing, with general disregard for their safety, while Gil had tried very hard, well hard, well hard-ly at all, to disengage Nick. By the time they'd arrived home they were latched onto each other like limpets and had half fallen out of the truck. In deference to their neighbours they'd behaved in an almost restrained fashion until they were in their foyer.

Once inside, with door slammed shut with a foot to it, Gil had pinned Nick against the wall and was kissing him as if he wished to retrieve his stomach contents - popcorn and soda. This thought made Nick snort a laugh and they lost mouth to mouth contact. Nick took the opportunity to breathe while Gil took the opportunity to further attack Nick.

He kissed, licked and nipped the flesh of Nick's earlobes, his neck - paying attention to the track of Nick's windpipe that Nick always found particularly stimulating. Nick would have just said 'hotttt'! Nick's whimpering and Gil's heavy breathing were the only sounds that could be heard, when Nick's hands dropped to Gil's ass and used a fair amount of strength to squeeze and pull Gil in closer to him, another sound was heard, Gil's groan. It was like an animal growl and they ground their hips together feeling each other's erection; their clothes almost rough on the sensitive skin of their penises as they strained against the cloth that was too tight to hold them comfortably.

Gil became the decision maker - this was not a prelude to a slower love making session - this was going to be hot and heavy and now!

He pushed away from Nick and dropped down onto his knees taking hold of Nick's jean's waistband as he settled on the floor in front of Nick. They had done this so often but it always delighted Gil that Nick's crotch was absolutely level with his face, he smirked at his prize and looked up to see Nick grinning from ear to ear in expectation of what was about to happen.

Gil, on this occasion at least, had no intention of using any delaying tactics, so he undid the belt buckle, opened the button, unzipped the jeans and with his thumbs in the waistband of Nick's jeans and CK's pulled them both down to just below Nick's scrotum. This was a smooth, practised action.

Nick's erection sprang jauntily from its confines nearly hitting Gil on the nose. They both laughed at the impertinence of its action, but Gil became serious again very quickly indeed with one purpose in mind. If Nick hadn't known better he would've thought Gil's look was evil, in fact it probably was.

Gil took the erect penis in his hand and pumped up and down a couple of times - just to remind it who was in charge here and then settled his hand at the base squeezing slightly and directing it towards his mouth. He licked his lips to further moisten them, (at that sight Nick groaned), and then he licked the already glistening head, tasting Nick for the first time in well...a couple of days....his tongue laved around the head and tried to force itself, under Gil's direction of course, into the slit and half way up the urethra, well a couple of millimetres anyway!

He moved his attention to Nick's testes, a particular favourite of Gil's since he loved how they were so neatly packaged. He licked at the skin and then tugged each testicle into his mouth sucking it in and then releasing it, his one unused hand stroked the scrotum at the same time on the other side to his mouth, rolling the testicle in his fingers and pulling it downwards from Nick's body.

His then moved the hand between Nick's legs using the thumb to press and stroke the perineum several times and then used his middle finger to stroke Nick's anus. He felt the muscles clench; he didn't intend to breach him but pressed against it and rubbed his finger up and down.

Nick was gasping breaths; head thrown back against the wall with his hands now firmly entrenched in Gil's hair, the soft ruffled curls one of his most favourite places to touch. Gil then suddenly opened his mouth wider and engulfed a sizeable proportion of Nick's erection into his mouth. 'Aaaarrrggghhhh!' was the response he got so he figured he'd got it right! He sucked as he moved off the erection; then he licked it thoroughly all over and then blew cool air on the hot, wet skin, not forgetting to move his hand up and down just a little and squeeze fairly tightly.

By this stage Nick had just about become incoherent, so Gil was right on schedule.

Gil thought it was time to employ his teeth a little so he used them to scrape the underside of the erection, and then licked to soothe the skin. He gently nicked the skin left around the head of the erection - there wasn't much since Nick had been circumcised - but enough to cause Nick to start begging. A good sound for Gil. He was feeling benevolent so he thought he would not tease for much longer!

Nick's 'oh', 'arrr' 'pleeeaaasse' and a couple of 'God Gil' and Gil thought he would go for the kill, so to speak. He resumed the pumping and sucking action with his hand and mouth. He could feel the erection become even harder and knew that Nick was approaching his orgasm so for his 'piece de la resistance' he released the hand holding the base and swallowed Nick completely - he was not a huge fan of deep throating but it worked magically as he moved just back and forth a little, swallowing and humming as he took the erection back in and sucking as he released it a little.

Gil could feel Nick pass the point of no return, his testicles tightened and clenched up, nearly into his lower abdomen and his whole body was starting to slacken except for the erection which became a softly encased steel rod and trembled as the ejaculation overcame Nick. Nick grunted as each spurt of semen shot out and down Gil's throat which Gil swallowed with some difficulty because of the constraints.

Gil held onto him, both with his mouth, suckling the penis as it softened and with his hands on Nick's hips. Nick's only option was to slide down the wall; Gil released the twitching penis and facilitated Nick's descent in a controlled manner using his hands. When Nick was sitting slumped against the wall Gil released him, looking at the sated man before him and then tried to move.........

"Ow, ow".

Nick's reverie had abated and as he looked at Gil, Gil had to confess.

"It's the knees Nicky, I think they're about to pack up".

"Well first things first, babe, let's deal the other swelling first, eh?"

And Gil became acutely aware that his own erection was still straining against his pants, and that it, too, was painful, but in a much more pleasurable fashion than his worn out knees.

"That would seem to be an excellent idea Nick, if I could just get into a more comfortable position?"

"I can help with that, no probs, but before...." He didn't finish the sentence because he leaned forward and captured Gil's lips in a kiss that was a specifically designed 'Stokes' special to render one Dr Grissom, speechless, senseless and Nick hoped, painless!

The End
