It had to be one of the hottest 4th of July's that anyone can remember, and having to work on a holiday always sucked. Greg was willing to do it though, especially since it was swing, which started at noon today instead of 4, rather than overnight. The biggest reason is that his paycheck has reduced some when he became a CSI, so the overtime always comes in handy. The only thing that was worse than working in triple digit heat on a holiday was that his new boyfriend was not working; he went to a party instead. Nick could have come in too to help out, but he knew that every case Greg worked on would help him learn their job. Also, if he weren't around, it would be easier for Greg to concentrate on the job at hand without his man there to distract him.

Now it's 10pm, and not only has Greg's finished helping with a B&E, he did some training with a newbie in the DNA lab who got suckered into working, when Hodges mysteriously came down with the flu last night and couldn't come in today. He's getting some clean clothes out of his locker, as well as his bath stuff, so he can shower before heading home to watch fireworks on television and maybe eat the leftover pizza that he and Nick ordered last night. Of course, he could shower at home, but he may as well use the county's water than his own; especially since the hot water in his heater is now being shared by two people half of the week. Ever since their friends had set them up one night a few weeks ago, Nick and Greg have become almost inseparable, or at least as much as they can with one of them on swing and the other on graveyards. They have to make a few adjustments and some compromises from time to time; but all signs are good that the two of them are on the way to being the real thing.

Greg's phone rings and he pulls it out of the pocket of the pants he just took off, opening up the flip. "Hello? Hello?" No one's there, so he closes the phone and sets it on the locker shelf with his ID and gun, shutting his locker before he grabs the body wash and other things from the bench. "Weird, no caller id...wonder who was calling me? I'm sure Nick is pretty close to drunk at Robert's by now." With a small giggle and a towel on his arm, Greg makes his way to the shower room to wash off the sweat and dirt of the day, all alone in the quiet of the almost empty building. It wasn't so bad working today, in fact with just that one case that Warrick helped him with; Greg was done by 8:30, so he was hanging out in the break room having some delivery Chinese with the new DNA girl. While he and Marta were talking about this great audio book he's going to lend her, they said good bye to Warrick who decided to skip the rest of shift and beat feet out to his ladyfriend's house for dinner and dessert.

"Oh man is this water going to feel good." The water from the lab's showers isn't terribly hot or has too much pressure, so usually it's good for just cleaning. If you want a decent shampoo or massage your body, you go home instead. Once he finds a decent temperature, Greg loses his towel and moves under the spray. After getting all wet, he takes the body wash and one of the crappy county-supplied washcloths and starts to scrub his body, getting all the places that are especially sweaty and grimy from the heat and the desert dirt. First is his chest, then arms, stomach, and legs; and as he goes to wash his back, the washcloth is taken from his hand and a pair of soft lips start to go up his neck. Jumping at the touch, Greg turns around to see his lover standing there, also buck naked and slightly dusty as well.

"Hey, baby. Looks like I got here just in time." Taking his boyfriend's lips in a deep kiss, Nick begins to rub Greg's ass and that is rewarded with Greg wrapping his arms around Nick's neck. When they break, Greg kisses that square jaw and lets out a small laugh.

"What are you doing here, and where did you come from? I was facing the locker room entrance, and you can see almost the whole room from here." This causes Nick to laugh too then kiss Greg again.

"I came in the other way, through the cops' locker room. No one is around, so they didn't see me in just my towel."

"Ah...so sneaky is my boy." Greg kisses the cheek of the man he has begun to fall very hard for, and then he's rewarded with another kiss from the tall, dark and handsome guy who is becoming just as crazy for him.

"I am. Now.... where is the soap? I could use a scrub too." Greg takes the body wash bottle from the shower floor, and pours a little in the washcloth he takes from Nick's hand.

"Let me help you Nicky. Turn around...I'll get your back." Nick does as he's told, and Greg begins to gently wash the broad shoulders and back in front of him. "You never told me why you came down here and didn't stay at Robert's." It takes a few minutes for Nick to answer, since the look on his face is showing that he's enjoying the attention and touch that Greg is lavishing on him.

"I got bored. The food was good, and I had a few drinks, but I was feeling a little guilty that you were working and I was having fun." Nick backs up so his back is up against Greg's chest. "I was also a little lonely for you too. In the past few weeks, I've come to really miss you when you're not with me G."

Turning his head, Nick gives Greg a little peck before allowing his chest to be washed with the lightest touch possible with the cheap scratchy washcloths provided by the county.

"That is so sweet Nicky. It wasn't that exciting here...Warrick and I took care of a B&E, and then he took the rest of the night off; and I had some broccoli beef and flirted with the new DNA girl." He laughs and that makes Nick turn around, standing there looking at Greg with a shocked and almost pissed off look on his face. "What?"

"What do you mean, what!? I just got done telling you that I left a party early because I missed you, while you had dinner and were flirting with the new girl?" Greg smirks at the little hissy fit that Nick is starting to throw, because he's seen them before. This one has all the signs that he's jealous, and that makes Greg happy because it shows how much he really cares. A soft peck is placed on Nick's pursed up lips, which then start to unfold in to that trademark Stokes smile. Greg places his hands on Nick's behind, lovingly stroking the round globes. As he answers the accusation with light kisses up his partner's neck, Greg pleads his case.

"Nicky...I had something to eat with her..." More kisses, then moving to the collarbone. "Then we talked about an audio book, then with Warrick for a bit..." Shifting from the clavicle to the hollow below the Adam's apple, it's apparent that Greg's lips are having an effect on Nick's lower body. "Then she went back to the lab, and I read my email. Besides, she has it bad for Hodges, if you can imagine?" Both of them make a face like they smell something bad, and then start giggling. "You almost sounded as if you were jealous there, baby." Nick lets out a chuckle, and then sucks in his breath as Greg takes his balls in his grip. "Were you jealous?" Nodding, Nick pushes Greg against the wall of the shower room, pressing his lips against Greg's, seemingly as if to tattoo the feel of his mouth against the other one. When they come up for air, Nick starts sucking on Greg's earlobe, causing a gasp and a soft moan in return; then a choppy voice makes a request of Nick. "Nicky?"

"Yeah G?"

"Let me fuck you....I want to...please?" Nick's face moves in front of Greg's again, and that Nicky smirk returns before he starts to rub Greg's chest.

"I want you too....but we don't have any lube or condoms." Greg looks at Nick with his hand on his hip, then around them. He picks up a bottle from the floor and shows it to Nick.

"Conditioner....we've used that before..." Taking the two steps back in front of Nick, Greg takes his boyfriend's lips with his again. "Do we really need a condom? Who is the last person you were with before me?" Nick looks down then back at Greg.

"Some friend of a friend....two years ago; and I've been tested 4 times since then. What about you G?" It’s clear that Greg is trying to hide a smile when he answers Nick's words.

"Longer than that....and I've been tested too. So...what are we waiting for?" Nick shrugs his shoulders and takes Greg back into his arms while showing him how much he wants his boy with his mouth. A few more minutes, and Nick's voice is getting thicker with passion as he make a request.

"Fuck me G....I want you so much." Greg kisses Nick once again before turning him face first towards the tile of the shower, which still has the water running. As Greg's hand goes to work on Nick's ass, Nick moves his feet out, widening his stance and bending a little at the waist. First, Greg strokes the firm bottom of his lover, and then opens the conditioner bottle, spreading a little on his fingers. Two of them go into Nick's crack, headed for his hole; and when they make their way, a little hiss leaves from between Nick's teeth. "Oh yeah....that's good." Licking a shoulder blade, Greg moves his fingers in and out of that nice ass, and then starts to spread them as they leave.

"You like that Nicky? You want more, baby?" The lust in the air is getting thicker as Greg continues to play with Nick's butt, and both of them are getting harder with each sound the other is making. Slipping a third and fourth finger in, a groan from Nick makes Greg stop, a worried look on his face. "Nicky!?" Turning his head to look at Greg, Nick's eyes are half slits, filled with longing.

"Don't stop...it will just take me a minute...go ahead...please!" Greg smiles as he returns to his task and while moving his hand, he is rubbing his other hand over the washboard stomach of the man in front of him. "Now, G....please, baby....I need you." Keeping that hand on Nick's front, Greg holds his hard cock and slowly slips it between Nick's ass cheeks. Little by little, he's pushing in while Nick is moaning and his eyes close. Once his balls are just about touching his man's bottom, Greg strokes Nick's face.

"We okay? Just tell me when you're ready." Nick nods and turns back for a kiss, Greg almost lying over his muscled back.

"Now is good, baby." Moving one hand to Nick's hips, Greg begins to piston his hips in and out of Nick, who is doing the same only the opposite direction. After a while, they've begun to move in sync with one another, and there is no sound other then the water from the shower, the slapping of skin and heavy breathing. Then all of a sudden, Nick's hand snakes back to rub Greg's hip. "Come on G...I'm getting there." The tip of Greg's tongue goes in to Nick's ear before his arm moves to take Nick's red and weeping cock in his grasp. Slowly, he strokes the hard hot flesh, causing Nick to let out a groan that almost sounds like he's in pain; but if it is, it's a good kind of hurt.

"Is that good Nicky? Do you want me to keep sliding in and out of you? Let me move and see what you think." Greg spreads his feet a few inches, which causes him to push in a tiny bit farther and change the position he was in before.

"Oh God! Greg.... yes....that's it....oh please G, baby!" Greg has found Nick's sweet spot, which tells him that he will probably need just a few more thrusts to make his boy come. Some more kisses to Nick's neck along with slipping his grip to Nick's balls, is all it takes before a low deep moan comes from that thick strong throat. Then the tile in front of them gets a small shower of cum, little white ribbons all over the aqua squares; and Greg is right behind his lover with his orgasm, just about hyperventilating while he pushes feverishly into Nick's ass for the last few times.

When he's done, Greg leans on Nick's back, as Nick is lying on his own arms that are in front of him on the shower wall. Finally after a few minutes, Greg slowly slips out of Nick, and then picks up the discarded washcloth to clean not only himself, but Nick and Nick's little soldiers off of the wall. After this, he wrings the cloth out and tosses it to the dirty linen bin by the other door, and leans on his back next to Nick with a shy but satisfied smile on his face. Nick takes Greg's face in his hand, turning it towards him so he can kiss him once again.

"That was wonderful G....but I think you could tell. God, you've gotten so good in such a short time." Greg wraps his arm around Nick's waist to return the kiss.

"I had a very good teacher Nicky. So patient and kind that first night...we still need to get a thank you gift for them, for getting us together."

"Let's talk about that over some dinner. Why don't we go to your place, fire up the hibachi, and I'll burn us some weenies while we watch the fireworks? Huh? How does that sound?" One more sweet and tender kiss between the lovers before Greg answers.

"Yeah...that sounds great. Hey...I got that beer you like, some hot fudge for ice cream and some containers of salads. Maybe somehow I knew we'd be celebrating together. Come on...let's go get dressed and go eat."

My phone rings just as they pick up Greg's things and start out of the shower room, and I have to get out before they see that I've been watching them. It's hard for me to walk with the raging hard on I am now sporting after watching my two friends have sex with each other, and it was weird but not as weird as I thought it would be watching them. Even though I only want to sleep with women, I sort of thought it was hot to watch those two....they've had such chemistry for years, and now they can act on it. Luckily, I have on a long shirt over my shorts and no one is in the place so to speak; and I slip out the door of the locker room so I can answer my phone.

"Brown."

"Hey honey...when are you coming back? I thought you were just heading down to get some papers then coming home?" My girl...well, not really a girl at all, but very much a woman. She's a friend that, like Nick and Greg, I've been close to for a long time, just never had the balls to make a move on until I saw the result of Nick and Greg hooking up.

"I...had to uh... watch to make sure some evidence on a newish case was processed correctly. I'm just leaving now." Yeah...she's gonna believe that, but what am I gonna say in the hall of the CSI lab with two people just now walking past me.

"Uh huh...whatever Warrick Brown. Well, you can tell me the truth when you get here okay? Oh, don't forget the ice cream. Someone here wants some before she goes to bed." I smile so big with that reminder.

"Sure Sweetness. I'll be there as soon as I can. Oh, and one more thing.

"Yeah?"

"Tell Lindsey I'll get her the hot fudge too."
