Hey guys! So...this is my very first one-shot about these two... I'm a huge fan of this pairing and will probably write more so this is a sort of...you could say an origin story. Any upcoming stories will draw reference from this to a small extent.

UPDATE #1: Getting back to old stories can be very frustrating sometimes. Had to edit it a little and rewrite one entire section to be happy with it. So yeah, I got back to this one and at the moment I'm thinking about writing another one-shot as a direct continuation to this. I just thought that, you know, maybe some of you would like to read how Bruce actually 'kills' Clark in the end :) For now, enjoy this little baby!

P.S.: I have a cookie for each of you who can find the two quotes from the Justice League cartoon that I slipped in. Hint: Bruce says them :P

UPDATE #2: And now you can read the sequel to this right here: s/10980349/1/Aftermath

He thought about it. He thought about it before, but never quite so intensely. Or so often for that matter. Since their last encounter with the Injustice League he was unable to clear his head and think straight. All he seemed to care about was Superman. Thoughts of the Kryptonian's recent behavior have invaded his mind and started interfering with everything he did, both as Batman and Bruce Wayne. It has reached a point in which one of the Falcone's mooks managed to get a drop on him and would it not be for Nightwing, he would have been beaten to a bloody pulp by a common thug. Something was definitely wrong here.

Why was the Boy Scout so important to him all of a sudden? Sure, over the years they have learned to trust each other and formed a beautiful friendship, but Batman was never the one to put personal matters over work. On the other hand, he couldn't deny that the Kryptonian was acting far too strange these days. At least whenever he was around him. He wouldn't talk to him unless absolutely necessary and seemed to be avoiding him whenever they were off-duty. Superman, easily the friendliest member of the League...

He moved away from the monitor. It was hopeless. He didn't know what bothered him more, the fact that he worried about the big guy, or the fact that he couldn't figure out the reason for this overwhelming concern. He reached for his comm-link. Superman was currently on monitor duty at the Watchtower and he intended to make him talk, even if it meant dropping a chunk of kryptonite down the alien's tights.

„You seem very absent-minded." said J'onn dryly. „Is something bothering you?" He glanced at his team mate sitting in front of one of the many monitors. He hardly said a word since they entered the room and it almost seemed as if he was frozen in position. Intense blue eyes glued to the screen, arms resting limply in his lap, his glorious red cape draped over the seat. He seemed to be oblivious to everything around him.

„You don't wish to talk about it. I understand." said the Martian as he turned his attention back to the monitors.
Damn right he didn't want to talk about it. He couldn't. Not after what happened during the last battle with the Injustice League. His mind drifted off as he remembered the instance only to be abruptly brought back into the present by an incoming transmission from his comm-link. Shivers ran down his spine as he heard a familiar low voice speak up: „Superman, I need to talk to you. It's important." He tensed up in his seat: „I'm on duty. Can't it wait?"

„Monitor duty. J'onn can handle that. Meet me at the cave."

„But-"

„Now."

He let out a deep sigh. „Batman called. Says it's important. Can you-"

„Go." said the Martian, without moving his eyes from the screen.

Ten minutes have passed since he spoke with Superman and still there was no sign of him. It was unlike him to stall...he was definitely hiding something. One didn't have to be the world's greatest detective to figure that one out. Nevertheless, Batman remained patient. He knew that the Kryptonian couldn't pretend to be on his way forever. He stared at the monitor, browsing through the files he's been working with, out of habit more than anything else. He managed to briefly scan one more before he heard a nigh-inaudible rustle of fabric and felt a slight shift in the air, two undeniable signs of Superman's presence.

„What took you?" he greeted, without turning from the computer.

„What's so important that it couldn't wait until I'm off-duty?" Superman shot back, a hint of fake amusement in his tone.

Batman turned to him raising an eyebrow under the cowl. „Drop the act, I know something's bothering you."

„What are you talking about? I'm fine." said Superman, trying desperately to cover up his nervousness. He was never very good at hiding his emotions and he knew that Batman would see right through him, but still he tried.

„You've been acting unlike yourself since the last mission." Batman continued as if he hasn't even heard him. „What is it?"

The Kryptonian blushed darkly. „Unlike myself? What do you mean? I-"

„Don't make me ask again."

„I'm telling you-"

„Clark." Batman interrupted, a hint of warning in his voice. „I mean it."

The taller man looked down and remained silent.

„Well?" he asked, this time clearly irritated.

„I...I'm just worried about you. On the last mission...you almost died back there."

His eyebrow flew even higher. „I've been through worse."

„I know you have."

„So why don't you tell me what the real problem is?"

„I...uh...I..."

The expression that appeared on Superman's face startled him. And that look in his eyes...he was desperate, yes, but there was something more to that gaze than frustration...

Before he had a chance to react, the Kryptonian was all over him. He placed his hands over his wrists, leaned in and started kissing him. Surprise was replaced with outright shock and for the first time since he'd donned the cowl, Bruce felt completely helpless. With his arms pinned down by the bigger man's strong hands and his lips trapped in a bruising kiss, he had no idea what to do. He knew that pulling away was not an option unless the man himself decided to let him go and while the Batman part of him kept screaming to resist anyway, the part of him that was Bruce somehow felt content where it was. Clark's lips felt soft and tender and he couldn't help but close his eyes as the other man shoved his knee into his lap posessively, drawing closer.

The Kryptonian's warmth was driving him crazy, no matter how hard he tried to resist. He started returning the kiss, hesitantly at first, but as the other man's tongue shoved its way inside his mouth and started exploring it, he could no longer control himself. He could feel the Kryptonian's hands let go of his wrists and start tracing his body. His own hands flew up, grasping the back of Superman's head and back. He dug his fingers deep into the black locks, ruffling his normally perfect hairdo. The other man didn't seem to mind at all, in fact, it seemed that he really enjoyed it. Bruce could hear his utility belt fall to the floor and felt the knee lodge between his thighs. Clark finished the invasion of his privacy by pulling the cowl off his face.

Bruce jerked back and broke the kiss. He didn't like having his cowl removed like that and for a moment, Batman was back in charge.

„Clark, we really shouldn't be doing this."

„Why?" asked the other man almost breathlessly.

„We're teammates. Dating within the team always leads to disaster."

„You can't know that. Besides, so far all we got to was a kiss." Clark said with a grin.

Bruce shot him one of his trademark glares. „If my enemies knew I had someone special, they wouldn't rest until they got to me through her...or him."

Clark crossed his arms defiantly. „It's not like you're gonna have it easy, Bruce. I've got enemies of my own that would love to take the same kind of advantage over me."

„I won't date you because I don't like you. I'm not gay."

Clark rolled his eyes. „That kiss we just had tells me something else. And didn't you just say her or him? Come now, Batman, I thought you could do better than that."

„Goddamnit, Clark!" Bruce snapped. „You'd be a target even if you dated just Bruce Wayne, you don't need Batman in your life, too!"

„In case you haven't noticed yet, you became a permanent part of my life the instant we formed the League. It's too late to do anything about that as it is." He paused for a moment and his expression became frustrated again. „I love you, Bruce, and I've loved you for a very long time. It just became hard to hide after I almost watched you die on that last mission. If you had any idea what you mean to me, you wouldn't say things like that."

Giving his lover no room to argue further, Clark pulled him out of the chair into an embrace and started kissing him once more. Bruce jerked with surprise and started to struggle in a foolish attempt to get his mouth away from those perfect lips. Clark mentally rolled his eyes at the billionaire's pigheadedness and decided that his best option was to use it against him. He used his weight to force Bruce back into the chair and knocked the air out of his lungs with a silent thump. Breathless, Bruce had no option but to give up his fight. That goddamn son of a...for someone who was supposed to be so pure and virtuous, Clark sure knew how to play dirty.

Bruce stiffened as his would-be lover proceeded to remove the rest of his costume as if it was something he did every day. He jerked as he felt his cock slide out. That bastard...he must have used his super-speed to have done it all so fast. He supressed a moan when the other man's hand grabbed his shaft and ran down towards his foreskin, gently pulling it back. No way in hell would he give him anything. He wouldn't let Clark make him his bitch. Ever. He received one last brief kiss before his cock was trapped inside a surprisingly greedy mouth. The hot saliva spilling all over it was driving him especially crazy and he had to bite down on his lip to restrain himself from moaning. Damn, Clark sure knew how to give one hell of a blowjob... He was sucking him off just right, pulling at the pulsing veins teasingly.

Bruce was unsure of how much more he could take without going insane. He was half-lying, half-sitting there, with his eyes shut tightly and his knuckles turning white from gripping the chair, getting harder and harder with every second. It now cost him all his willpower to keep himself from moaning and crying. He could feel Clark's mouth release him and in spite of having his eyes closed, he knew that the other man was right above him. God, he smelled so good...

„Come on, Bruce. Stop it." he heard him say. He could feel his hand touch his chin gently and run up towards his mouth to wipe away the thin stream of blood coming from where he was biting his lip. „I know you like it, I can see it."

„N-no." the other man managed to push out of himself, surprised that he was capable of saying even a single word.

„Don't be so stubborn, you're enjoying the heck out of this."

Amusement was literally oozing from his voice and Bruce knew he was smiling without having to open his eyes. Still, his pigheadedness knew no bounds. Especially when it came to arguments with Clark.

„You can't...make me..." he said, opening his eyes just enough to glare at him.

„I already have." Clark retorted, a mischievous smile spread across his face. „But now I want to hear it."

Without giving Bruce any further room to argue, he pressed his body against his, trapping his bleeding lips in another kiss. He gripped his rock-hard erection and proceeded to tease and tempt him. Bruce took in a shallow breath. He could take it no more and let out a pleasured moan.

Clark's lips curled into a smile. He was satisfied, he won. He knew that Bruce was probably already contemplating various methods of how he's going to kill him once this is over, but for now he didn't care.

And that's it! Hope you guys enjoyed it :) Feel free to review, both praise and constructive criticism are very welcomed and much appreciated (grammar corrections too)!
