Lex had never consciously experienced Clark on red kryptonite. There had been instances in the early days of their friendship, before the breakdown of their relationship, when he had entertained the thought that Clark was using drugs. Those days were long in the past, however, and the Clark standing before him now was certainly not the Clark he had known back then.

Six years had passed since the final disintegration of their friendship. Clark was 25 now; a college graduate and fresh-faced reporter for The Daily Planet working alongside his long-time friend Chloe Sullivan. But, this definitely wasn't that Clark.

This Clark had swaggered into his office hours after everyone else had gone home. In lieu of his typical off-the-rack suit and deceptive rectangular frames that hid his bright green eyes and accentuated the angle of his jaw, Clark was clad in dark, wear-worn jeans and a green t-shirt that brought out the colour of his eyes and clung to the muscles of his torso.

Instead of lingering in the doorway with his head down, or storming in with accusations flying, this Clark had flung his very expensive black jacket over the back of a nearby chair and placed his palms flat on the surface of Lex's desk before leaning forward suggestively, a small smile tugging at his lips.

"Lex," the voice this Clark spoke with vibrated through Lex's chest and straight to his groin where it wrapped around his already hardening cock and held on for the long haul.

Lex cleared his throat. "Clark, can I help you?"

Clark glanced down at the desk, through the desk actually, to take in the effect he was having on the other man. "Yes, Lex, you can."

Lex swallowed. He was dead in the water. Feelings he hadn't acknowledged about Clark in half a dozen years were suddenly screaming for recognition, and Lex swore that the next time Clark spoke his cock was going to explode without ever having been touched.

"And how would that be?" Lex was struggling to maintain his composure. He was rock hard and well aware that Clark could see right past the blotter and laptop that would have shielded his state from anyone other than a man who had the ability to see through solid objects. Not that he would admit to Clark he was aware of that particular capability.

"By shedding the pretense of being the almighty Lex fucking Luthor, losing the suit, and spreading yourself open for me to take as I please."

Lex didn't think he had ever heard Clark say anything more intense than an occasional exclamation of 'shit' under his breath, and he wasn't sure which was more shocking; his use of the word 'fuck' or his rather interesting suggestion.

Clark smirked at him, pushed off the desk and moved around so they were on the same side. He reached out to stroke Lex's cheek with one hand before pulling the chair around to face him.

"You want me, Lex, I know you do."

"I used to want you, a long time ago."

Clark glanced at his lap and grinned brightly at him. "A part of you still does, by the looks of it. I'm going to suck you, Lex."

He opened his mouth to voice the protestations he knew he should be making and found his words choked off as one of Clark's fingers stroked up the length of his cloth-covered shaft.

"Take off your clothes, Lex," Clark leaned down and ghosted his lips along Lex's jaw and a silver chain with a small, red pendant swung free from beneath his shirt and bounced against Lex's shoulder softly. "Or I'll take them off for you."

"Clark," he was silenced by an angry kiss, teeth nipping at his lips and tongue thrusting inside his mouth roughly, claiming ownership.

"Take them off or I'll rip them off."

Lex hesitated, half wanting to see what it would be like to have Clark strip him. His hesitation was enough to force a growl from Clark's throat before his clothing was literally ripped off his body.

Clark dropped to his knees between Lex's legs and without preamble sucked the head of his leaking cock into his mouth. Bowing upwards with a gasp, Lex threw his head back against his chair and thrust into the mouth surrounding him, trying to get more. Clark didn't disappoint. Sliding down until Lex's cock was enveloped in his throat, he swallowed.

"Clark!"

Green eyes bored into Lex's dilated grey ones as one eyebrow arched inquiringly. A finger joined the cock in his mouth before pulling out to draw a swift, wet trail back to the puckered entrance to Lex's body.

Pushing his spit-slicked finger into the other man's body, Clark sought out his prostate and started stroking in time to the rise and fall of his mouth. Lex was panting hard, trying to thrust up and back at the same time, running his hands through Clark's thick, dark hair, and finally clutching at his neck. His fingers tangled in the thin, silver chain around Clark's neck and one particularly forceful thrust against his prostate had him pulling roughly at the chain until it snapped while climax washed over him and his body slowly wound down.

Clark lifted his head to watch Lex, who was slumped in his chair fully sated, eyes closed and head lolling backwards. The tiny, red stone pendant slid off the broken chain to the floor between Lex's feet.

"Lex?" The confidence Clark had exuded was no longer present in his voice, which brought Lex's head snapping forward as Clark started to scramble to his feet.

"Clark, wait!" Lex lurched out of his seat awkwardly, now fully aware of his naked state of being.

"I'm sorry, I-" Clark was backpedaling, groping blindly for his jacket. "I should go, Lex. I'm sorry."

"Move another inch and I promise I will find a way to-to... I don't know. Just wait, please." Lex couldn't remember the last time he had asked Clark to stay in his presence, let alone used the word 'please' in the same sentence. It was enough to stop Clark in his tracks.

"You want me to stay?" he asked uncertainly. "After what I just did to you, you want me to stay?"

"Yes, please."

Clark fidgeted with the hem of his t-shirt, not quite able to look his former friend in the eyes. "I don't know what I was think-"

"No more lies, Clark," and fuck if he wasn't standing stark naked in front of the man he used to love – scratch that - still did love, asking for what he had taken to thinking of as 'the big truth.' Not quite what he'd planned when picturing this particular scenario.

"I don't know that I can trust you anymore," he whispered softly, still picking at the hem of his shirt and adding a foot shuffle to the growing list of physical signs of discomfort.

Lex sighed. "Clark, you just broke into my office, ripped my clothes off, and proceeded to give me the best blow job I've had in a very long time, and I didn't call for my security team or press any silent alarms, ask you to leave or try to fight you off. That's more than I can say for any other encounter we've had since you were 19. I think it's time to clear the air. You tell me yours, I'll tell you mine."

"Your what?"

"My secret."

"Which one?"

Lex shook his head, a smile playing at his lips. "The big one, Clark. The one I've been denying for a decade."

"Oh."

"Will it help if I go first?" Lex had an odd feeling building in his stomach. He was nervous. He was afraid, even, of the implications of what he was about to say. The realization had struck him only moments before and it had been like a tidal wave. Years of repression gone to waste, he thought.

Clark nodded meekly, still not meeting his gaze.

"I'm in love with you." It was enough to bring Clark's head snapping up.

Barely registering that he'd started to speak, the words tumbled out of Clark's mouth in a rush. "I'm an alien, and I've loved you since I was fifteen."

Silence reigned in the office until Lex laughed immediately breaking the tension that had been building. "You win," he said, twining his fingers in Clark's hair and pulling him down until their lips met. He filed away all thoughts of Clark's earlier strange behavior for the time being and focused on the feel of Clark's mouth against his. Questions could wait. For now, there were years of pent up desires and repressed emotions to make up for.
