“You know,” Bruce huffed, “I never took you for a strategist.”
Clark dipped down to give Bruce’s ear a playful nibble. “Learned from the best.”
It was getting increasingly difficult to form coherent thoughts. Luckily, Bruce could multitask.
“I think it’s a good plan,” he said a few minutes later. “Joker and Luthor are both familiar with our tactics by now. It wouldn't hurt to - ah! - to have the element of surprise.”
Bruce’s breathless growly voice was doing something to Clark. He wanted to hear more of it.
“Did you really just compliment my idea without any criticism?” He was even more breathless than Bruce, despite the fact that he doesn’t actually need to breathe. “Or is it just because I’m inside you right now?”
Bruce chuckled. “What if it was?”
“Then I should take full advantage of this opportunity.”
He thrust hard, abruptly, which coaxed a string of unholy noises out of Bruce. The fist that was clutching Bruce’s hair gave it a tug.
“Tell me,” Clark growled in Bruce’s ear, “tell me how good my plan is.”
Bruce had gone beyond his multitasking capacity. He tried to speak but only a whine came out. The pull at his hair was harder this time. If Clark were not so invulnerable, he would have ten long scratch marks forming on his back right now.
“Tell me!”
“Your - ahh! - the pla- oh God Clark! Oh fuck!” Bruce screwed his eyes shut, mouth hanging open, spewing relentless moans and profanities at different octaves.
Clark could feel himself hitting the end of the tunnel with each thrust. He desperately tried to lean down as close to his lover as possible, so that his stomach rubbed against Bruce. The sudden contact made Bruce squeal, but he didn’t protest. So Clark let go of Bruce’s hair and moved his hand between the two of them, gently stroking him up and down. It didn’t take long for his hand to match the pace of his hips.
“So good!” Bruce moaned. He leaned up and bit Clark’s shoulder as hard as he could. Clark gave a yelp, not out of pain but out of the sudden pleasure. The bite mark barely registered before disappearing. Bruce licked the area. He slid a hand around Clark’s neck and pulled him closer. His tongue swiped at the skin just below Clark’s ear. Then he thought of the dirtiest, filthiest thing he could say and whispered it into Clark’s ear, somehow managing to include the plan.
Goosebumps erupted all over Clark’s flushed skin, he trembled as a long whine escaped his mouth. He knew he was close. He had to bring Bruce close too. He picked up the pace. With a little bit of flying, so as not to lose his balance, he now used both of his hands on Bruce and did the thing he knew to be Bruce’s favourite. It earned him a nice loud guttural moan. He felt Bruce clenching around him, the heels of his feet digging at Clark’s lower back.
It was precisely seven seconds later when they went over the edge simultaneously, holding onto each other for dear life.
It was another several minutes before Clark gently pried away from Bruce and rolled over on the bed. He pulled a blanket over them.
“You know what would be the perfect element of surprise when we go to fight Luthor and Joker?” Clark murmured as he pulled Bruce closer.
“What?”
“Making out in front of them. Passionately.”
He smothered a laughing Bruce with kisses until they were exhausted enough to fall asleep.
