Summary: For the LJ Icon Challenge.

Warnings: Rated NC-17. m/m.

Notes: This is from a challenge that was floating around LJ. People picked one of my icons, and I wrote a short little story about it.

Clark and Lex had a very firm rule: No sex in the office. Unfortunately, they also tended to feel that rules were meant to be broken. It had led to more than a few close calls; once Lex's Executive Vice President of Finance walked in about five seconds after they'd pulled up their pants, and Lex's assistant still couldn't look Clark in the eye after barging in on some pretty intimate groping.

And yet, this in no way dissuaded Clark from dropping by LexCorp headquarters after lunch for some stolen moments of nookie. Lex never needed much convincing to break their pact of workplace chastity. A hand down his pants, and he was eager to chuck the rulebook right out the window.

Clark was on his knees, face buried in Lex's lap, eagerly working him over--office sex was best hard and fast--when the intercom buzzed, making him bang his head on the desk in surprise.

"Fuck!" Lex stabbed at the intercom button. "Not now, Jenny! I'm busy."

No doubt she knew exactly what he was busy doing, and she sounded appropriately mortified. "I'm sorry, Mr. Luthor. It's just--your father's here, and he insists on seeing you. I'm not sure how long I can--"

"I will not be kept out of my own son's office," Lionel's voice boomed in the background.

"Oh my God!" Clark started to scramble up, trying to zip his pants as he went, but the door was already opening and there just wasn't any time.

Lex pushed him beneath the desk. "Stay under there!" he hissed.

"Too busy for your own father these days?" Lionel asked as he stepped into the room, his voice irritated and disapproving.

"I'm always too busy for nuisance visits if that's what this is." Clark thought it a remarkably poised comeback for someone whose half-hard cock was still hanging out of his pants.

This observation, unfortunately, gave him ideas. Lex and his father launched into a complicated discussion of agricultural futures. He ran his tongue along Lex's shaft, and Lex's voice broke on the word "speculation."

Clark grinned. This was all the encouragement he needed.

It was a revelation that cocksucking could be done so quietly; usually Clark sounded like something out of a porn video. Lex somehow managed to keep up his end of the conversation, but he was breathing increasingly heavily, eyelids drooping half closed, sweating as if he were sitting in a sauna.

"Are you ill?" Lionel finally asked. "You look very flushed."

"It's hot in here, don't you think?"

And then the pork belly talk resumed. Clark stroked Lex's thighs, caressed his balls. It wasn't going to be long now.

"Maybe you need more time to consider your position," Lionel said snidely.

"Yes!" Lex shouted, coming in Clark's mouth. He took a deep breath and then did his best to recover. "I'll make the decision on my terms, when I feel satisfied I have all the information I need, not before then, certainly not just because you're pushing me on it."

"Fine." Lionel did not sound happy. "Get back to me when your charts and graphs tell you what a real businessman would feel in his gut."

The door slammed, and Lex wheeled back from his desk and pulled Clark out by his arm. "What the hell was that?"

"I had to do something to keep from dying of boredom. Pork bellies, Lex?"

"I'm getting a lock put on that door," Lex declared.

Clark kissed him. "That's probably a good idea. The no-sex-in-the-office strategy certainly hasn't worked out too well. I have to get back to the Planet. I'll see you later." He kissed Lex again and headed for the door.

"Clark?"

"Yeah?"

"Think you can come back tomorrow?" Lex's grin was filthy with suggestion. "The new lock will need testing, of course."

Clark grinned back. "Of course. You can never take workplace security too seriously, after all."
