Catwoman

Batman was cut short, he took his eyes off for a fraction of a second and he found himself swept off his feet. Just as he braced for impact on the ground he felt a swift yet strong hand catch him, the female's warm breath ran down his back. "Why'd you do that for? Don't tell me you've had a change of heart and are going to hand those jewels in.."

Catwoman held Batman there for just a moment with her hand pressed against his chest, enough to say those words but before he could say or do anything further, her hand pushed him back. Though she was having fun with Batman, she could have kept him engaged for more time, but hearing those sirens, she knew the cops would be here anytime soon. As many skills she had, she knew she couldn't hold cops and Batman together so she needed to wrap up now.

"Don't worry my darling" as his back touched her, she pressed a piece of cloth on his nose and mouth from behind, while her hand shifted down from his chest, wrapping her arm around his waist to grab him.

Batman could sense something was up, but he was having a good time. He knew he couldn't bring Catwoman in, at least not today. They already had their way out so it didn't matter to him. He was just having fun.

He felt her grip on him get tighter and then felt a very strong but sweet smell and a sense of drowsiness washed over his body. It didn't take long for the rag to knock him out cold but he drifted off into unconsciousness.

Catwoman felt Batman's body sinking into her arms as the chemical took effect, his head lolling back **** into her shoulder. But she kept the rag over his face for a couple more seconds after he was out, making him breathe more fumes through his nostrils, and ensuring he'd be well and truly helpless for more than enough time.
