"Mmm, purrfect."

Selina Kyle slowly lowered herself into the gigantic warehouse by the long wire, her long legs attached to the cable by her clawed boots. She moved carefully, her skintight grey bodysuit silently stretching as the criminal known as Catwoman stared at her prize, visible among the various boxes and cases within the empty building.

"Whoever owns you doesn't deserve to, my lovely." She whispered to herself. "They can't take good care of their possessions, and as per a thief's duty, it's up to me to liberate you."

Her prize was a perfect blue-white diamond set into a necklace, kept inside a glass case in the middle of the warehouse. Her eyes almost sparkled with its luster. Catwoman slid down the long steel wire and sprayed mist all around the case, checking for laser-security systems. Sure enough, there was a web of red lasers all around the case. She carefully reached down and flicked her diamond-tipped claws out of her gloved hands, placing one of them on the case and using them to cut a perfect circle into the glass. After removing the circle of glass, she slowly reached in, checking for any other security measures. After she was satisfied that there were none, she grasped the diamond and purred, pulling it out and placing it around her neck before looking at her reflection in the glass.

"I don't know, blue isn't your color." A female voice said from behind her.

Catwoman jumped and whirled around, just in time to be grabbed by vines and bound like a mummy as the plants pulled her into the air by their tendrils, moving on their own. She was lifted into the air and held upside-down as metal slats rolled down over all the doors and windows in the warehouse, sealing her inside.

"Ivy!" Catwoman hissed as she writhed and struggled inside her vine cocoon. "What are you doing here?"

"Setting my trap, of course." Ivy said as she walked out from the shadows. "Glad to see you recognize my handiwork. I've been after you for a while now, Catwoman…"

Catwoman couldn't help but stare. Ivy was wearing her usual dark green one-piece bodysuit to compliment her light green skin, but something was different about it. For one, it was now a corset that thrust her sizable breasts upwards, and she had added a pair of garter stockings and thigh-length boots. Also, her long red hair was done up in a bun, to show off her neck and face. She carried a riding crop in one hand, and Selina didn't like the look of this at all.

"Did you know you've been curtailing my activities for a while now? Taking my prizes when you pull your little thefts?" Ivy asked as she walked over to the mummified Catwoman, stroking her face with the crop and slowly moving it down to the bound burglar's rear. "You've been…pardon the pun…a thorn in my side for a while now."

She quickly brought the crop down on Catwoman's perfect rear, making the bound woman scream.

"And now, I've finally caught you. You know how hard it is to catch a cat?"

"Of course I know." Catwoman snapped, cutting through the vines with her claws. "And now you're dead meat, sister!"

She leapt out of the cocoon and slashed at Poison Ivy with her metal claws, her eyes a study of fury. Ivy just barely managed to duck out of the way, with Catwoman tumbling on the ground and jumping to her feet.

"Cats hate being restrained, you know!" Catwoman growled as she jumped onto Ivy, the green-skinned woman rolling onto the ground and hitting the back of her head on the hard floor. "And if you think for a moment you'll get away with this, you've got another think coming!"

She jumped up and kicked Ivy twice, then backflipped over and over onto the crates in the warehouse, leapt for the skylights, and thrust her head forwards to break through the large glass panels, with her claws ready to grab the paneling separating the glass.

THUNK!

Catwoman saw stars falling before her eyes as her head connected with a glass that was far more solid than it looked. Her vision blurred as a throbbing pain made itself known in her now-aching skull, and she just barely managed to grab the very edge of a metal panel separating the panel, the tips of her claws barely holding on.

"Oh, don't be in such a hurry to leave, my little kitty cat." Poison Ivy said as she slowly rose from the ground on a gigantic flower, the roots acting as an elevator. "I've got some fun to have with you…"

"P-Plexiglas…" Catwoman moaned as she tried to grasp tighter on the window panel, her vision spinning as she felt all dazed.

"Yes, I set this all up for you." Poison Ivy said as she stood up, her corset accentuating her sizable bosom as she held out a hand to Catwoman. "Now grab on tight, and I can get on with your due punishment."

Catwoman's vision spun and faded as she realized she had no choice and slowly reached a hand out to Poison Ivy, who smiled mockingly. The woman's green skin seemed to shine like emeralds under the midnight moon. Suddenly, Catwoman's vision faded altogether and she let go of the window, dropping through the abandoned warehouse with such a speed she screamed. Suddenly, she stopped inches from the ground as a long rope made of twisted vines and tendrils grabbed both her feet and lifted her upside-down, holding her at face height with Poison Ivy.

"Goodnight, my sweet kitten." Ivy said as she kissed Catwoman, making the spandex-clad burglar's eyes close in a swoon. "Sweet dreams."

Catwoman's mind drifted off to sleep as the vines slowly lowered her to the floor, removing her mask and applying a sticky leaf to the place where her head had connected to the panel. The vines then unzipped her latex bodysuit and tossed it into the corner, leaving Catwoman completely naked before her captor. Ivy seemed pleased to know Catwoman went commando under her bodysuit, and licked her green lips as her long red hair draped over her naked captive. Now the real fun was to begin…

Ooh, this is going to be hot! My girlfriend and I have both dressed as Catwoman and Poison Ivy in the past, and this fic is giving me some ideas…
