Chase.

Catwoman slowly backed up until she reached the edge of the roof. Blowing a kiss, she backflipped and dove down but only to lash out her whip and swing across to the apartment building across the alley.

"Selina!" Batman yelled as he leapt after her. He spread out his cape and triggered an electric charge to stiffen the cape's memory cloth make it act like a hang glider. He landed on the nearby apartment building's fire escape platform and ran up the steps to give chase to Catwoman on storey above him.

Catwoman jumped, rolled, and somersaulted over vents, ducts, and other rooftop obstacles. Batman lacked her finesse and used his brute strength to run and jump after her. Deciding that the chase had gone on too long, Batman took out a batarang from a belt pouch and flung it at her. She ducked and rolled to avoid it and sprung to her feet. She flicked her whip out to latch unto an overhead gargoyle and swung across the alley. Batman pulled out his grappling gun and zipped up to the next building's penthouse patio.

Batman was impressed that she made it up before he did and expected her to be in a fighting stance but instead she stood there and unzipped the front of her skintight catsuit down to her navel.

"What are you doing?" he asked, stopping a few feet from her.

"I'm hot from this chase," she purred, removing her cowl to free her pixie-cut dark hair. She gave him a mischievous wink and a grin before sauntering away from him towards the patio door.

"Whose place is this?" the Dark Knight asked, cautiously following her into the penthouse suite.

"I'm housesitting for a friend," Selina answered, kicking off her boots.

"A friend?" Batman scoffed.

"Why are you surprised I can't make friends in high places?" 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. Her bet paid off, Batman just stood there and watched her walk up to him instead of trying to apprehend her.

"Selina..." Batman muttered when Catwoman pressed her soft body against his armored form and kissed him fiercely. He towered five inches over her atheletic 5'7" frame.

"Bruce..." she smiled at him.

"..."

"Like I said, I make friends in high places," Selina whispered. "Or have you forgotten our first fling at the Wayne Foundation Charity Gala? I can't forget the taste of your lips." She kissed him again.

Batman had to keep up with his playboy alter-ego persona during the day, which meant he sleep 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, 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 disabled 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?"
