Slick

As Kat stepped through the mirror into the other world she gasped as the wriggling tendrils at her back door suddenly stretched inside. She stumbled forward as she gripped her rear with a hand. "Easy!" she muttered as the whole creature shivered as if invigorated by this place.

She took in her surroundings and noted the simialrities and changes. It was her room, except without any of her junk or clothes on the floor, and instead of glass the windows were mirrors. Out of curiosity she opened a draw on her dresser to find nothing inside. Weird, but she supposed it wasn't the strangest thing she'd encountered recently. Between her legs, her panties rustled.

Out of curiosity, she focused on the ceiling again and floated once more into the air. So, she could fly here too! She shuddered as the tendrils in her ass stretched further, writhing a bit more excitedly. It seemed the more she used the creatures' powers, the more they used her. She floated back to the ground and landed lightly. The tendrils relented slightly, but not completely. She shivered slightly at the sensation.

The longer her living lingerie teased her, the closer and closer she got to being tipped over the edge into a shuddering orgasm. Every time she'd come in these panties she'd warped somewhere through space and time, so she figured she should probably be ready to leave when the moment came. This put her on something of a time-frame for exploration. She shivered as a tingly tendril stroked her labia. Perhaps not a very long time-frame.

With this knowledge, she threw open her bedroom door and set out to explore this strange place. She passed through many residential rooms similar to her own, bedrooms, living rooms, kitchens, all with mirrors for windows and a distinct lack of looking lived in. And of course, occasionally she'd open a door to find gravity on the other side completely changed. Her flying panties were certainly a boon, but damn it if they weren't distracting.

At one point she stumbled as a long tiny tendril slipped out of the back of the waistband and gently traced up her spine before retreating quickly back inside when she looked over her shoulder. By the time she'd been searching for what she assumed was about an hour, there were enough tendrils writhing and shoved deep into her sphincter to nearly be a pulsing phallus, not to mention those giving her pussy attention. She was considering just flying the rest of her time here to avoid the distraction walking caused as her thighs rubbed against the slippery yet incessant advances.

Before she made that decision however, she came across her first signs of life. She walked into a bedroom that had lacy black webbing stretched across some of the corners, and focused heavily around an antique vanity. She slowly approached it as her underwear hummed. It seemed to be made of the same stuff as that creature she encountered before. As she got next to it, she watched as several small rolling balls of wriggling tendrils scampered out onto the counter. One noticed her and approached the ledge. In a flash, it leaped at her waist, but before her hands could even move to stop it, a black tendril whipped out from her panties and swatted it back onto the counter.

It crawled away in a daze, and her panties hugged her hips protectively. Or perhaps possessively, she wasn't sure. She patted her backside in reassurance, then shuddered "Gah!" as the tendrils swelled into her erogenous zones with greater vigor. She wouldn't be able to hold out a whole lot longer.

There were two other exits from the room besides the one she'd entered, and she chose the one surrounded by the dark substance. She passed through a few more rooms with the slick webbing becoming more frequent, and more of those small creatures darting about furtively. As she walked through one room, she froze as a familiar voice rippled behind her.

"You just couldn't stay away, could you? Well, I'm positively flattered." it cooed.

Kat spun around, then groaned as more tendrils sprouted to lap at her swollen clit. "What-mmm-what are you? What-nnah-what is this place?" she stuttered through the creeping advances.

What she'd mistaken for a pool of the goo on the ground, rose to form the sinuous figure that stood before her. It stalked towards her, and Kat floated back into the air with a thought, barely resisting the urge to moan as the tendrils' motions accelerated. The thing stopped and observed her. "Interesting. The formless one still holds some sway. Usually...hmm. They must be quite fond of you." she flicked her fingers towards her waist and Kat trembled as her panties swelled into her as if in pride.

"To answer your burning questions, this place is...complicated." it gestured around with a slick hand. "And I am even more so."

Kat bit her lip as she involuntarily rocked her trembling hips against her panties. She wouldn't be able to hold out much longer, and she still had barely learned a thing! "But I will tell you this about me." The creature glided towards her and looked up. "Whatever my kind touches, so can I." It lifted its fingers in the shape of a V to its liquid lips and lapped between them with a long black tongue.

Kat cried out in ecstasy as she felt the same tongue at her pussy, sprouting from her possessed underwear. At the last moment, she thought of her room as her orgasm crashed into her. She folded out of existence as space warped around her, and crashed into her bed as she bucked her hips furiously against the ministrations of the tendrils and ethereal forces between her legs.

A few minutes later, she'd came down, and groaned as she felt the tendrils slide out of her folds. Through groggy eyes, she looked down at her hips as her panties pulled themselves off and scurried back over to their home in her dresser. If she didn't know better, she'd say they almost looked drunk. It was already late in the night, and she needed only lay there a few minutes more before she was dreaming peacefully.

In the mirror world, Kat's room had altered slightly. Laced about a few of the corners was a slick black webbing, all leading back to the top drawer of the dresser where a cluster sprouted out. Inside, something stirred.
