Chapter Text
The strange feeling curled in Clark’s chest as he flew slow circles around LuthorCorp.
Usually, he went flying to clear his head. Something about zooming through the sky eased all the tension in his mind, whether the sky was clear or not, his thoughts usually were by the time he touched down.
But Clark had been out here for hours, watching the pale blue sky sink into starry darkness. He didn’t feel any different.
That strange feeling was still there, winding against his heart and lungs, wrapping around his mind like chains, flowing through his cells like the moonlight.
It’d started that morning.
Clark was not a social media person. He knew it was meant to pull people in, an algorithm designed to keep feeding people dopamine until they were blindly buying whatever thing had been discreetly advertised.
He made an exception on certain days, allowing himself to browse the comments of his articles on the Daily Planet. He’d smile softly at the encouraging words, the praise for Superman.
He would then always inevitably see a hate comment. His smile would slip into a scowl, he’d close the page, put his phone away and forget about it a few moments later.
But the message he’d seen that morning did more than just make his smile fade.
It was posted under an article he’d written about Superman stopping a bank robbery—most comments were supportive. A few laughed and joked around.
Only one was mean. No, it was meaner than mean. It evoked pure hatred with only two words.
‘Fuck Superman’
It wasn’t exactly the most creative comment he’d ever seen. In fact, Clark knew for a fact he’d seen worse in his line of work. He shouldn’t take it seriously.
He shouldn’t care. And yet, something about it made him feel strange. It was made worse by the fact that the person who posted it did not seem to care who saw.
They posted it with their full name, linking back to their public account with their picture and bio and three-million followers and blue checkmark.
It was like Lex wanted him to see it.
No, it was not the worst thing Lex had ever said, but something about those two words had Clark’s blood pounding all day, and no amount of flying was making that feeling go away.
Clark had slowly flown tight circles, coming closer and closer to the building. The night air was cool, his cape blowing behind him as he gazed at his own reflection in the pitch-black windows.
Clark’s reflection of furrowed brows and thoughtful somber eyes was gone when fluorescent lights flipped on inside the laboratory.
He raised his eyebrows in surprise, taken slightly aback as Lex Luthor stared back at him, his eyes dark and glaring.
Clark flew off, shooting back up towards the sky. There was a metallic bang, the stairwell door on the roof opening and Lex stepping out just as Clark flew over.
“What are you doing?” Lex growled.
“Who, me?” Clark feigned innocence, his voice wavering just slightly.
He hovered yards above Lex, in the perfect position to escape. But he found himself lingering, the cool breeze coming back, blowing his cape again.
“Why are you spying on me?”
“Spying?” Clark flew down lower, still hovering over the roof. “I was not spying on you.”
“You’ve been out there all afternoon—I saw you.”
“But I wasn’t spying!”
Clark had never been so close to Lex before, having only really faced him through a screen in the past.
Lex was always so judgemental, so critical of Clark’s journalism, of Superman’s choices, as if he understood what it was like to carry the weight of the world.
Clark looked at him now. Clark could sense Lex’s heart beating even from feet away, reminding him this was just a human.
Anyone could say anything they wanted online. He was just as human for getting upset about it.
Well, not upset. He’d still yet to name the feeling that still flowed through his veins.
“Then get lost—” Lex narrowed his eyes. “I don’t want you creeping around here. Don’t you have someone else to bother?”
Clark watched as Lex turned to go back inside. His heart started pounding, slight panic in his chest.
“Wait—”
“What?” Lex snapped, turning back around.
“Aren’t you wondering what I’m actually doing? Since I’m not spying on you?”
“I don’t particularly care.” Lex rolled his eyes. “I’m sure whatever it is, will just piss me off, now go—”
“Wait—” Clark landed down on the roof with a soft thump, Lex growled as he turned back around.
“What the hell do you want?”
“I was just wondering if you meant what you said online—”
“What?” Lex’s eyes narrowed and Clark went on, his heart pounding loudly in his own ears.
“On Clark Kent’s latest article about me—” Clark started, and Lex rolled his eyes.
“Yes, probably.” Lex nodded. “Whatever I said, I probably meant it. Why, does that hurt your feelings?”
Lex tilted his head slightly, almost mockingly. Clark felt his face warm just slightly.
“Maybe a little—”
“You know, you would think that you’d have the super-human ability to not care. You should have thicker skin than to cry about something I said online.”
“Who’s crying?” Clark tried his own angry glare at Lex. “I just think you should be more careful, anyone can see that stuff, you know.”
“Why should I care?”
“Because everyone will know you want to—”
“Want to what?”
“Everyone will know you want to fuck me.”
Clark hated saying that word. It was so vulgar, so nasty. But it seemed to finally name the feeling that had been coursing through his veins all day.
“What the fuck did you just say?” Lex stepped closer. Clark could hear Lex’s heart pounding faster.
“That’s what you said, isn’t it? In your comment? You said you wanted to—”
“Listen here—” Lex hissed, reaching out to poke Clark in the chest. “I don’t know what kinda game you’re playing, but you better get lost before I—”
“Before what?” Clark grabbed Lex by the wrist as gently as he could, knowing even his lightest touch would trap a human.
“Don’t touch me, you fucking alien!”
Clark let go of Lex’s wrist and he yanked his hand back, his face flushing slightly. Clark had felt Lex’s pulse racing like crazy, could still hear it now.
“You really like throwing that word around, huh? Is that because you want it so bad?”
Lex was glaring at him, shaking slightly in rage, his face flushed. Clark stared back, hoping it was not rage that had Lex’s heart racing.
Clark really hoped he was right. He did not let his uncertainty show, he just pressed on.
“You do, right? I mean, you’re the one who said it—” Clark’s voice shook just the slightest bit, showing his nerves. “And—I’m offering. If that’s what you really want, maybe that’s what you need to, you know, chill out.”
Lex was staring at him in a way Clark couldn’t read. The only sound between them was Lex’s breathing, their racing hearts.
Clark was starting to feel like he might have miscalculated. Lex was angry, and Clark should fly away before he really flipped out.
But he didn’t, he just stood there looking at Lex, who still seemed too stunned to speak.
“What the hell is wrong with you?” Lex finally asked, his voice barely a whisper.
“What’s wrong with me? You’re the one who put it online! So, do you want it, or not?”
“You’re a freak!” Lex stepped back, turning to go back inside. “You better get the fuck out of here, or I’ll—”
“How about just my mouth?” Clark’s panic was rising higher as Lex walked away. “I’m serious, I wanna taste it—”
Lex froze, his hand on the door handle, his posture rigid. Clark couldn’t tell whose heart was racing faster, the sounds of both pounding in his ears.
Lex slowly turned back around, stepping closer to him, that pounding sound even louder in Clark’s ears.
“Did you just say what I think you just said?”
“That depends—” Clark’s voice was shaking again. “Did you think I said that I wanna suck you off, Lex?”
“Yes.” Lex’s voice was very small as he locked eyes with Clark and nodded.
“Then, yes. That is what I said. What do you think about that?”
Clark was shaking with nerves, but he just stood still, watching Lex, hearing Lex’s heart racing.
“I think you’re fucking crazy.”
“But you want it, right?” Clark licked his lips, noting the way Lex seemed to be staring. “Like I said, it could help you calm down, and I’ve been thinking about it all day.”
“All day?”
“Ever since I heard what you wrote, I’ve been thinking about it. So, do you want it?” Clark licked his lips again. “Because I really do. I want to taste you, please?”
Lex was no longer angry. He was just staring at Clark in a way Clark couldn’t quite read, his eyes dark and his face tinged red.
“Would that make you shut up and go away?” Lex finally asked.
“Yes.” Clark nodded, trying not to grin too eagerly.
“Then, fine. I’m a man of my word. I don’t post anything online that I don’t mean.” Lex turned back to the door.
Clark followed him inside, the stairwell eerily quiet without the blowing wind in his ears. There were only the sounds of their footsteps as Clark followed Lex down the hallway.
Lex came to a door at the end of the hall and they stepped inside.
It was dim in the office, only the city lights coming in through the floorlength windows, the curtains pulled back.
There was a click as Lex locked the door before turning to face him. Clark stared back at him, their mutual heart beats pounding in his ears again.
“Well—” Lex snapped impatiently, his eyes flicking over Clark’s body. “What are you waiting for? Get on your knees—”
“Right.”
Clark got down on his knees, watching as Lex reached to undo his pants. Clark licked his lips again, an eager hum in the back of his throat.
His hum broke into a moan as Lex pulled his cock out. Any part of him that doubted Lex’s enthusiasm was gone as he saw that Lex was hard for him.
“You look perfect.” Clark breathed. “I need to taste you.”
“Let’s see how super you are at this—” Lex muttered.
Clark gave him a knowing glance before leaning in, wrapping his lips around the tip of Lex’s cock. Lex sighed softly, groaning louder when Clark stuck his tongue out and slid down, taking in the whole length of his cock.
Clark moaned, sucking him and sliding back up. He reached up, wrapping one hand around Lex’s shaft, stroking him.
“Fuck—” Lex hissed, one hand going to the back of Clark’s head, the other resting firm on his shoulder.
Clark slowly pulled off, saliva trailing from the tip as Clark took a breath and glanced back up.
“You taste really good.”
“Shut up—” Lex snapped, pushing Clark’s head back towards him.
Clark opened his mouth again, Lex moaning softly as his hips snapped forward, slamming his cock down Clark’s throat in a way only Clark could take.
He sucked Lex harder, still stroking him with one hand. He did taste good, perfectly human in a way that seemed to flood all of his cells with warmth like sunlight.
His taste, the feeling of his cock on the back of Clark’s throat has his body growing hotter. His own arousal was growing, curling in his core and making his own cock strain hard inside his costume.
He pictured Lex’s cock inside him, stretching him open with ease the way he was doing to Clark’s mouth. Lex’s fingers were gripping his hair, and he pictured Lex holding him tight, slamming inside him.
“Fuck—You take my cock so good—” Lex moaned. “Had no idea—”
Clark just moaned in response, feeling Lex’s precum leaking onto his tongue. The human taste sent pure lust through his whole body.
He went deeper, Lex gasping at the feeling before going harder, rocking his hips and moaning.
“Yes—feels so fucking good, fuck—” He moaned. “Getting close—”
Clark moaned, looking up. Lex’s face was flushed, his eyes closed.
“I’m fucking your mouth, Superman—” Lex’s voice was strained. “You’re gonna swallow my load—”
Clark swallowed, Lex gasping, his voice breaking into a loud moan as Clark tasted the seed spilling down his throat.
Lex clenched his teeth, his moan tapering off, his hips rocking an unsteady rhythm. Clark stroked him, milking out the last of his seed onto his tongue as he pulled back and swallowed.
Lex pulled out of his mouth, leaning all of his weight onto the hand on Clark’s shoulder as he panted hard.
Clark just sat there, taking in the sounds, the heavy scent of arousal before Lex finally straightened up and pulled his pants up.
“How was that?” Clark bit back a smile as he reached up, wiping his mouth on his arm.
Lex shot him an annoyed glare, but didn’t reply as he zipped his pants back up. Clark breathed, the taste of Lex still in his throat.
“You’re just going to fly off now?” Lex seemed slightly weak in the knees as he walked around to the other side of the desk.
He opened a minifridge and took out a bottle of water. He didn’t offer any to Clark, just drank a few gulps.
“I guess.” Clark shrugged.
He couldn’t look at Lex, staring at the door instead. His blood was boiling, his body aching, but he was not about to ask for reciprocation.
Lex would never get on his knees for Superman in a million years.
But Clark still lingered, just in case he was wrong.
Lex slowly walked back around the desk, staring down at him in a way that made Clark’s heart race. It was so dim in here, could Lex tell how red his face was? Could he tell how turned on Clark was?
It seemed so obvious.
“What are you waiting for? A thank you?” Lex snapped after a moment of silence. “Get lost—”
Clark jumped to his feet and started towards the door, his blood still pounding hot through his body.
“Wait—” Clark lingered at the door, looking back.
Lex was leaned against the desk, staring out the window.
“What?” His voice was tired, only a twinge of annoyance as he took another drink of water.
“Was that okay? I mean—was it good?”
Lex didn’t say anything for a moment, Clark hearing his heart race.
“Yes, it was good.”
Clark grinned proudly, warmth blooming in his chest.
“Okay, cool—” Clark waited another second. “If you ever want it again, just let me know.”
Lex turned his head slightly in Clark’s direction. Clark went on.
“Just leave me another comment. I’ll know what it means, it’ll be like our code word.”
Lex didn’t say anything, but Clark could still hear his heart pounding as he went back into the hallway and took the stairs to the roof, taking off into the sky.
He barely made it home, pushing his bedroom window open and soaring inside in one quick motion. He got undressed, leaving his costume in a heap on the floor as he laid on the bed.
His hand was on his cock, Lex’s taste still in his throat as he came with a soft moan, his eyes falling shut.
Clark laid there, breathing in the aftermath, the fire finally cooling in his veins. He slowly opened his eyes and went to clean up and change, coming back and finding his phone where he’d left it charging on the bedside table.
He scrolled through the comments on his article. Several hundred had sprung up throughout the day, leaving Lex’s buried.
For a moment, Clark was worried Lex’s language had gotten the comment removed, but after several moments of scrolling, he found it.
‘Fuck Superman’
Lex almost always turned off replies to his own comments, as if it was his smug and superior way of saying he was not going to engage in online discourse.
It was his refusal to hear any criticism of his own hateful words, but Clark saw now that there was a reply, where there hadn’t been that morning.
It was Lex, he’d replied to himself only a few moments ago, a single thumbs-up emoji.
Clark smiled, that warmth blooming in his chest as he realized that was meant just for Superman, just for him.
Maybe Clark had managed to chill Lex out after all, just a little.
For now.
But he couldn’t wait to get to work tomorrow, to bust out the best possible article he could, just to see if Lex commented those same two hateful words.
