Chuck closed his eyes and sighed happily, smiling as he listened to the rain beat down on his roof. He had always loved the rain- he couldn't explain it, and couldn't remember how or when his obsession with it began. It was just such a beautiful process; something no one could induce or stop. It was purely a process of nature, occurring only when nature felt it necessary, and ceasing only when the land it sprinkled had its fill.

Sure, he had always been more electronics based than anything else; circuit boards were his calling. But there was something about the rain, which was one of the only things that could pull him out of the electronics-induced, somewhat comatose state he always fell into as he worked.

Chuck lifted himself off of his bed and walked over to his window. He opened it, closed his eyes, smelled the rain in the night air, and sighed happily again. He thrust his head out the window, eyes still closed.

"Bartowski!"

"Gah!"

His eyes flew open and he jumped at the sound of the gruff voice in front of him, hitting his head on his window on the way up. He winced and rubbed his head as he looked up to see John Casey, NSA Colonel and former handler (more recently something along the lines of partner, teammate maybe, since Chuck was becoming a full-fledged spy). He was leaning slightly away from Chuck with a smirk on his face.

"What were you trying to do, Bartowski, kiss me?"

Casey crossed his arms over his chest menacingly, but his smirk remained. Chuck hadn't quite caught on to the fact that it had been a joke, however.

"What? No! I just… I… I wanted… and then… and I… and you…"

Chuck cut himself off before he could make an even bigger fool of himself with his incoherent babble.

"Relax, Bartowski, it was a joke," Casey snapped, smirk gone. "Now let me in. I'm getting soaked out here."

"Oh!"

Chuck realized with a start that Casey was dripping wet, and quickly stepped away from the window so that he could climb in. Chuck handed Casey a spare clean towel that had been sitting on his dresser. Casey thanked him and began to dry himself off, starting by dabbing at his pant legs. Chuck watched Casey, somewhat awestruck as beads of rain danced on Casey's muscles as they flexed, and glistened in his hair. Casey quickly finished drying everything but his hair, and reached the towel above his head to do so, but stopped when he saw Chuck staring at him, a dumbstruck look on his face.

"What?" he barked.

Chuck started at the abruptness of his question and was pulled out of his fantasies.

"What? Nothing, no reason."

He looked away and ran his fingers through his soft brown curls awkwardly. Casey was tempted to do the same, but by the time the thought had left his brain and reached his arm, his spy training had kicked in and pummeled the urge. He reached up and dried his hair instead.

"So, why are you here?"

"What?" Casey asked again, in a normal tone, peeking his face out from underneath the towel. He then disappeared under it again as he finished drying his hair, pulled it off of his head, and looked around the room for somewhere to put the now soaking towel.

"Why are you here?" Chuck repeated. "Do we have a mission or a date or something?"

"Date?" Casey spat, his head snapping up to meet Chuck's suddenly panicked eyes.

"What? No, that's not what I meant! I meant something like ann… appointment! Or recon! …or undercover work… you know, spy stuff."

Chuck's words were hurried, each trying to be the first out of his mouth, but by the end of his rushed ramblings, the haste in his voice had weakened. Chuck grimaced, kicking himself internally for making an ass of himself. He was made even more uncomfortable by Casey's unceasing stare as he tried to read Chuck's face. Casey's own expression was one of false impatience and annoyance. He refused to let his expression slip and reveal that his heart had raced when Chuck had said the word "date."

Chuck's face heated up as Casey continued to gaze deeply into his eyes, searchingly. He was thankful for the lack of light, which concealed his fiery cheeks.

Suddenly, he noticed a droplet of rain glimmering on the agent's jaw, illuminated with a blue tint by the moonlight streaming in through the window. He reached out to wipe it away. Casey stumbled back a step, shock apparent on his face, and he glanced quickly at Chuck's hand, and then back into his deep brown eyes. Chuck's hand had retracted slightly, hesitating when Casey had moved away from him, but his arm was still outstretched.

"Chuck, I… we…"

Casey couldn't form the words he needed to make Chuck lower his hand and stop staring at him in desire. He couldn't force himself to say what he needed to say to reject Chuck. Chuck took a step forward and brushed his fingers gently along Casey's jaw line, wiping away the droplet. Casey closed his eyes and leaned into Chuck's touch. Before he could open his eyes again, Chuck had a hand on either side of Casey's face, holding it in place, and suddenly his lips were covering Casey's, kissing him with a passionate urgency.

Casey stiffened, his eyes opening. He quickly clamped them shut again, however, as he began to count down from three in his head, mentally preparing himself for the hurt that would no doubt fill Chuck's eyes when Casey pushed him away in…

3…

Casey steeled his nerves, making himself impervious to anything. Rejecting Chuck would hurt them both, but they would just have to deal. After all, Casey thought, it was in both of their best professional interests if they weren't involved, right?

2…

Casey put his hands on Chuck's chest. He would push lightly; the kid wasn't very heavy.

1…

Casey suddenly forgot what he was counting for at the feel of Chuck's tongue running over his lips in an attempt to make Casey open them.

It worked.

Casey's mouth opened automatically, allowing Chuck inside. His hands slid across Chuck's chest and around to his back, pulling him closer. Chuck, pleased with Casey's reaction, slid his hands down the agent's neck, his shoulders, his pecs, as they continued to kiss, tongues tasting, lips pressed together forcefully.

Finally, the need for air caused Chuck to break the kiss. He smiled his adorable smile at Casey.

"So this is what you came here for," Chuck said slyly. He leaned into Casey's neck, breathing hot and moist, making Casey shiver, and mumbled, "I don't blame you."

Casey moaned slightly as Chuck bit and sucked at his neck. He kissed his way up Casey's neck and jaw until their lips met again. Casey explored Chuck's mouth with his tongue, dominating the kiss and making Chuck moan back eagerly.

Oh, Chuck was making the most delicious noises now. His hands were under Casey's shirt, his body pressed close, his mouth talented and luscious. Casey wanted more- he wanted to make Chuck shout, he wanted to feel him underneath him and strip him and…

Casey pushed Chuck backwards slightly towards the bed. Chuck pulled his hands out of Casey's shirt and dropped down onto the bed, grabbing Casey's collar and pulling him down too.

Casey crawled on top of Chuck and kissed him, slipping his tongue into Chuck's mouth , unbuttoning his shirt at the same time. Casey covered Chuck completely, his hands reached every part of Chuck's body, his tongue took control of Chuck's mouth, until Chuck couldn't think, couldn't breathe, and couldn't wait any longer as an uncomfortable pressure built in his Buy More-issued slacks. He turned his face, stopping Casey again and making him growl.

"Easy, big guy," Chuck smirked. He put his hands on Casey's chest and rolled them over. He adjusted himself so that he was sitting on Casey, pressing them groin to groin. He wiggled his hips slightly, rubbing Casey in just the right spot and making him groan and shift underneath Chuck. "Let me try," Chuck said as he pulled off Casey's shirt.

He tossed it aside and paused to admire Casey's impressive muscles. He ran his hands over Casey's shirtless upper–half. Casey gripped Chuck's arm and pulled him down into another deep, forceful kiss.

Chuck's hands slid their way down Casey's body. He slipped his fingers under the waistband of his pants. Casey stiffened as Chuck began unbuckling his belt. He turned his face away, hesitating.

"Chuck…" he moaned.

He had meant for it to sound more intimidating; instead it sounded as if he was barely keeping it together, which was exactly the case because Chuck 's mouth was again on his neck, making his brain defunct and bereft of all rational thoughts.

He ran his hands up and down Chuck's slim body and met the nerd's lips again. He barely noticed Chuck now working on the button of his pants.

"Chuck," Casey tried again, speaking against Chuck's lips, desperately trying to regain some form of coherent thought.

Casey fought hard against the blinding possessing lust that threatened to quickly overwhelm him. He had little success; with every thrust of Chuck's tongue, the anchoring weight of Chuck's body, every fantasy of Chuck all coming true at once, Casey could do nothing to fend off Chuck's advances. He couldn't possibly say no.

Chuck's fingers hooked Casey's boxers and began to tug down slightly.

Shit.

Casey pushed Chuck off of him suddenly, with more force than was necessary, and Chuck let out a small yelp of surprise as he was flipped onto his back on his bed next to Casey. Casey shot up out of the bed and immediately buttoned and belted his pants.

Casey couldn't do this. He couldn't want to do this. What the hell had he been thinking?

"Jeez, what the hell was that for?" Chuck asked as he watched Casey search frantically for his shirt.

Casey didn't answer. He located his shirt and pulled it on, mumbling something that Chuck couldn't understand.

"Casey, talk to me," Chuck said.

"This was a mistake," Casey said through his rigid emotionless expression, glancing around the room.

"What was?"

"Me coming here. This was a mistake. None of this should have happened."

Casey stared at Chuck's Tron poster.

"A mistake?" Chuck's eyes shone with hurt. "That's what this is to you?"

Casey, who had been avoiding Chuck's gaze, turned to him when he heard the hurt in Chuck's voice.

"Chuck, we can't do this." Casey knew Chuck wouldn't accept that as an answer, but he had to try something to make Chuck understand.

"Why not?"

Casey could see the emotions behind Chuck's eyes threatening to rupture his temporarily guarded expression.

"I'm not you asset anymore. I'm your teammate. Technically, we're allowed to do whatever we want!" Chuck whisper-shouted, not wanting to alert Morgan, who was in the other room playing a video game with an online team (Chuck had respectfully declined when Morgan offered him a position earlier).

"It's not that simple," Casey tried again.

"Ok, let me make it simpler. Do you or do you not have feelings for me?" Chuck asked, his tone revealing the depth of his emotions; this question was killing him to ask.

Casey made no move to respond. He merely watched as the hurt in Chuck's eyes spread to become the tension in his shoulders, the twitch of restless fingers, the uncomfortable shift from one foot to another.

"Casey," Chuck tried again. "Do I mean anything to you, or not?"

Casey's mouth opened to respond, but his voice got caught in his throat.

Nothing he wanted to say sounded right, anyway.

Chuck looked away, unable to wait any longer for a response.

"Get out."

Chuck's voice lacked any emotion or infliction, which, in a away, was worse than any pain Chuck could have spoken with. It gave Casey a dull ache in his chest.

Casey's voice found him again, and his expression matched his desperation to make Chuck understand.

"Chuck, please…"

"I said get out, and if you don't leave willingly then I will force you out myself," Chuck said softly, but fiercely, and his eyes exposed the pain of rejection and longing and desire.

The ferocity and intimidation in Chuck's voice might have impressed Casey, if it were not for the fact that Chuck was directing it at him. Unsure of how to respond, and realizing that he had done enough damage for the night, Casey silently obliged.

He turned on his heels and climbed back out through the window, soon soaking wet as the rain poured down.
