C.S.I., Nick Stokes/Warrick Brown, a little time off
This could also be in answer to the prompt "playing to win".
When they're not processing a scene they sometimes get toghether. At first, when there was no DNA to match or blood to find, they would have a drink together, in a bar, on one or the other's sofa. Later they would use their time off to challenge each other to various one-on-one sports, which Nick usually won, and they never made bets.
Once, after a week on the case of an abused and murdered kid, they argued during hoops and Warrick threw a punch but Nick just threw his hands in the air and stepped back, red-faced and sweating and walked off the court. On Monday Warrick brought him coffee and apologized with a shrug and open hands and Nick just nodded and said "two sugars, next time."
That evening they met for drinks and long after midnight Warrick asked if Nick really meant what he'd said about love and sex.
"Why do you ask?" Nick said, slouching on the sofa beside Warrick, game controllers long abandoned for pillows, both of them speaking in low, sleepy tones.
Warrick only laughed lightly, rolled his head toward Nick.
Nick smiled patiently, "Do you want to know if I love you or if I'd have sex with you?"
"Man, I just asked if you meant what you said."
Nick shrugged. "When don't I?"
"Yeah."
"Maybe what you should ask," Nick suggested, shifting closer, "is my definition of love."
"Or sex," Warrick corrected.
Nick leaned in for the kiss first, but Warrick took control quickly, so that while the first touch was soft and warm and Nick, the second and every one after was deliberate and unabashedly Warrick. Lips on lips soon became tongues and teeth and when Warrick swung a leg over to straddle Nick and massaged him through jeans Nick drew back. "What happened to foreplay?"
"Playstation?" Warrick suggested, working at zippers.
"Are you kidding me?" Nick asked, watching Warrick's hands, his own on Warrick's waist, moving up his ribcage, sizing up an opponent.
"We could wrestle," Warrick suggested, taking Nick's cock into his hand, "See who loses."
"You'd lose," Nick said, but his voice broke in the middle of saying it so that it wasn't very convincing.
They still get together sometimes when they're not processing a scene. Sometimes it isn't planned and Nick shows up at Warrick's and they cook steaks and play Madden and they laugh about something and Warrick will touch Nick's arm and Nick never doesn't touch back. Sometimes it is planned and they meet at Nick's and play basketball, and fuck slow and long in the shower. Always kissing. Nick likes to kiss.
Sometimes they schedule vacation days so they overlap, and drive out to the dessert and fuck in Nick's truck and stay in one of the few hotels where they've never processed a scene and practice a little boxing or wrestling. Usually boxing. Warrick always wins those.
