Apologies for this being late, my other writing projects are keeping me busy.
The main reason I thought of putting Killer Frost into this story was because of Assault on Arkham, but I'm thinking of the Louise Lincoln from before New 52 continuity because I think she's more visually interesting. For your imaginative purposes, anyway.
As always, both comic book logic and crazy sex fantasy rules are in effect.

"No, aah, don't take the crates east until they've been - fuck! - checked for radiation. Shit, shit, shit! You there, get another crew scanning for fragments. Aaah!"
Selina Kyle was doing her best to direct the recovery of all the pieces of Kryptonite that Ra's al Ghul had owned. It was a simple enough task, made difficult only because of Superman's cock pounding inside her. He stood just behind her and she kept her arms clasped around his neck, the difficult angle meaning that her luscious ass was pressed hard against his body. It left Superman's hands free, though, one of which caressed her breasts and the other played between her legs.
"They're... almost done," she managed to breathe after her next orgasm.
"You've done well." Superman gave another little thrust to punctuate the statement, making her groan in pleasure.
"What about the others?"
"Renovation of headquarters is nearly complete. We're prepared to take a large portion of Gotham, but we'll hold off on that for a little while because I'll be gone."
That cut into Selina's pleasure despite the cock still moving slowly inside her. She arched her back even more so that she could get a glimpse of his face. "You'll be gone? What if..."
He leaned down to kiss her. "Don't worry, it won't be long. I decided that once all this Kryptonite is packaged in lead, I'll drop it into a black hole, just to be absolutely sure. Even at top speed, I can't reach the nearest black hole instantly, but it will be a few hours at most. We're just being cautious."
"I understand, but..." Selina found herself looking around the work site suspiciously. Now that they were expanding, she was more concerned about loyalty than ever. All of the workers were League of Assassin members that Superman had fucked thoroughly, so there shouldn't be a problem, but still... "The more people we have, the more likely it is that we'll be betrayed."
"Are you really that concerned? How often do
you
think about betraying me?"
"Never!" Selina realized how quickly she'd reacted and smiled wryly before grinding back against his cock. "Alright, you've made your point, big guy. And I chose these women for that very reason. But you can't fuck the entire planet, so eventually something will have to give."
"Yes, I've been thinking about that." Superman stared west, perhaps even looking directly at Gotham. Seeing an edge of realism in his eyes that she'd never seen before, Selina felt reassured. "Once we get established at headquarters, I have some ideas I'd like to discuss with you."
"Of course. Hey, you there, stop shoving tha-aaah!"
When she finished coordinating the work, Superman bent her over one of the crates and fucked her hard and fast. After so much slow and luxurious sex, her pussy was flooded and desperate, so she came over and over until her world went black.
She was vaguely aware of Superman setting her down and whispering something before leaving, but her world was too hazy to recall much. When she came to, not so much time had passed, yet all of the scrap metal from the ocean liner was cleaned up and the crates of Kryptonite were simply gone. Selina was lying on one of the benches with the League of Assassins around her.
"We've finished the cleanup, Mistress." One of the assassins dropped to one knee. "Can we return to Gotham now?"
Selina waved at her wearily. "In a minute."

While Superman was off-planet, Barbara ordered everyone to keep their activity low key. That wasn't difficult, since most wanted to relax or celebrate after the victory, and Gotham itself was pretty quiet. With some time alone, Barbara brewed a perfect mug of coffee and then sat down to pore over all her data.
She'd been in email contact with some theoretical physicists and refined her theory considerably. M-waves were now divided into three different categories: w-waves that signaled extra-dimensional manipulation by different Writers, e-waves that enforced broad changes on the world, and c-waves that seemed to provide the motivation for all of the changes these beings made.
One thing had become very clear: these entities had standards of morality utterly different from humans. Based on the w-waves around disasters, the Writers would cause intense suffering and death so long as it brought them more c-waves. And people that didn't give off enough tended to die in conflicts or just fade away.
For that reason, she wasn't sure how she felt about her newest readings. Defeating Ra's al Ghul and claiming Talia had produced high levels of c-waves, and building the new headquarters in Gotham was sending their average levels climbing ever higher.
That probably meant they were safe from the Writers for now, but were they doing the right thing? Perhaps they were already being manipulated. Eventually Barbara decided that they couldn't afford to care about the whims of these extra-dimensional monsters. If they managed to create a world where most people were safe and happy, that was good enough for her. Stability seemed to lower c-wave levels and prompt the Writers to bring chaos, but perhaps Superman could create an exception.
Superman glided up behind her and Barbara smiled warmly at him. "You're back already?"
"Already? The trip took longer than I thought." He put his hands on her shoulders and she leaned back against him comfortably.
"Considering that you left the solar system... actually, you would have to have been traveling faster than the speed of light. That doesn't make any sense."
