Penthouse suite.

If anyone bothered to stare into the moonless night they could barely make out two silhouettes running across rooftops, leaping across alleys, and climbing up fire escapes.

"Whose place is this?" Batman asked after zipping up to a rooftop patio.

"Mine," Selina replied, looking over her shoulder as she opened the patio door and stepping inside the penthouse suite. "Are you coming?"

Batman scanned around him, making sure noone had trailed them, and then followed Catwoman inside, closing the door and blinds behind him. "I didn't know you could afford a place like this," he said, noting the cat themed artworks around the condo.

"I saved up," she answered, unzipping the front of her skintight catsuit down to her navel to reveal her ample cleavage.

"Right," he scoffed, eyeing her suspiciously as she removed her cowl to free her pixie-cut dark hair.

"Why are you surprised I can't make money legitimately?" Catwoman put down her backpack and peeled off her skintight catsuit. She could not see his pupils due to his cowl's white lenses but she could feel his eyes staring at her tone naked body.

"At Penguin's Iceberg Lounge?"

"Gambling is legal in this state," she noted.

"Yes. I do recall I paid off your hundred thousand dollar debt to Cobblepot at the Wayne Foundation Charity Gala several years ago," he said.

"The night of our first fling," she remembered with a wide grin. Pressing her soft, naked body against his ceramic-Kevlar body armor, she kissed him.

Batman had to keep up with his playboy alter-ego persona during the day, which meant he slept with models, starlets, and socialites to maintain his image. He was keeping an eye on Selina at the charity event at the Gotham City Royal Hotel and to get closer to her, but he let himself be seduced by her and the two of them slipped away to fuck in an office. After some polite excuses for leaving the ball early, they fucked in his limousine back to Wayne Manor, much to the chagrin of his butler (as well as driver, mentor, private confidant, and friend to his darkest secrets) Alfred. They then fucked for hours, with breaks to rehydrate, leaving his massive master bedroom in disarray.

"Don't worry, Bruce," Selina smiled. "I turned off the security cameras. Your secret is safe with me."

"Of course," he answered gruffly. He had no reason not to believe her because she could have blackmailed him at any time, exposing his true identity to his vast rogues gallery of criminal psychopaths. But she hadn't. Of all the allies in Gotham, why not have the Dark Knight as her protector when things get hairy? This would not be the first, nor last, time he thought, that he would let her go after they had sex.

"So how do you take this thing off?" Selina traced her finger in a heart-shape across his broad armored chest. "What's the combination?"
