Fights off the evil speedster

Kara considered her options for one more second as heat grew between her legs and her nipples firmed with arousal. The supervillain's offending fingers had found a maddening rhythm around her lower lips, slightly retreating from their previous invasion to tease with wicked slowness. No, the guy wasn't slow - no matter how fast she reached for him, his body shifted faster than her to dodge... but he kept his teasing slower than her own superspeed, having found how this slow, hair-raising touch annoyed and excited her. Each time she tried to grab his hands directly, he shifted them to her breasts, rubbing both nipples with considerable skill. Or maybe Kara simply lacked the experience and everything he did seemed like considerable skill to her.
Just as furious as aroused now, she changed tactics. She **** herself to calm down after failing to get him for the third time, allowing him to return to his teasing. Everthing was happening very fast - an outside observer would have only counted three seconds since the whole thing begun - but also slowly as she measured time. One more second and she was flushing once more. Two, and he took a couple of involuntary breaths. Three, and her hips relaxed a bit, her legs spreading an inch or two involuntarily.
"Ah, found the right touch, didn't I?" the masked speedster said and chuckled.

Kara punched him in the face as fast as she could. Lying on the floor, with him above her and finally believing he'd won, he was too late to dodge the blow entirely, no matter how much faster he was. She failed to nail him right in the mask and knock him out but even as he rolled aside, her superstrong punch found him in the shoulder. Rolling out of reach as Kara came to her feet, she could clearly see his entire left arm wasn't working very well - if at all.
"You bitch! I'm gonna **** you six ways to sunday for that! You won't dare show your face anywhere but the whorehouse."
"Really? Whorehouse?" Kara quipped. "When are we, the sixties?"
Kryptonian woman and masked evil speedster launch themselves at eachother, thinking more **** than humiliation.

Kara got the best of the first exchange while he still adapted to an obviously bruised arm; she clipped him by the narrowest of margins and sent him sprawling twenty feet away after taking a half dozen superfast punches in her midriff that only momentarily annoyed her.
The speedster got the best of her in the second exchange though; he rolled away from her slower downward blow that aimed to tag him while he was still prone then run off... for a tenth of a second. In that time, he'd run around the room six dozen times and accelerated to supersonic speeds; as Kara rose again and searched for him, he slammed his fist squarely into her right breast. The young Kryptonian gasped - a hundred pound missile at well over the speed of sound had his her as hard as an antitank rocket and while she was invulnerable, certain areas were less **** than others. She clutched her breast more at the total surprise of the pain rathr than its magnitude, which gave the supervillain time to perform another slam at the second juicy target.
"Not as invulnerable, are we?" the speedster snarled. "I'm gonna hit those till they fall off - till you beg me to fuck you instead!"

As the pain in her firm breasts slowly faded, Supergirl realized she had miscalculated; the supervillain could hurt her after all...
