"I'm back!" Nina announced as she entered her flat, it has been a long day at work and she wanted to relax, but more pressingly, she needed something from Enko.

She had been feeling in a bit of an adventurous mood that morning, and had maybe let her urges get the better of her, she had Enko put her "unchastity belt" as she called it, on her. Functionally identical to a normal chastity belt, but with vibrating dildos built-in. They hadn't been turned on, but running around all day fully stuffed had started to drive her a little bit nuts.

Enko greeted her with a smile, and after some brief exchanges on how their days had been, Nina asked. "Okay, can I have the key for this please?" she pointed down at herself unnecessarily.

"Nope." Enko casually says, her smile turning into a smirk.

Nina lowered her eyelids, a bit too tired for her antics. "Whaddaya mean "Nope? Come on now, I gave yo-"

"Yeah, you gave me the keys. I'll give them back to you, but you gotta earn them!", she giggled to herself briefly, obviously she had planned on doing this from the get-go.

"... and what did you have in mind exactly?"

As if on cue, Enko pulled a loop of rope she had ready nearby. "Well, isn't it a shame? You've had that on for what, 8 hours now, but I didn't get to use the remote control for any of it!" She brandished said control and waved it infront of Nina. "Let me have some fun with you, and then I'll untie you and give you the key."

Nina's blush intensified, she shifted her thighs slightly, when Enko was insistent it was fairly hard to change her mind, getting some sexual release would be better than just waiting for her to relent, probably...

"'Have some fun with me' is pretty vague..." She paused in thought for a moment "One hour."

"Three!"

"...two."

Enko puffed her cheeks slightly "Three!"

Nina sighed. "Alright, three... I so don't have the energy for this right now, I'll be back in a minute..." Nina relented, heading off to the bathroom to relieve herself and get freshened up.

Enko didn't really kid around with this kind of stuff, her idea of fun usually amounted to extremely tight bondage and forced orgasms, something Nina was very used to at this point, but still she managed to overwhelm her every now and again.

She bound Nina's arms behind her, twisting them around and up as far as they could comfortably go, complete with a simple shibari harness binding her breasts and a little of her torso. The chastity belt was a little in the way so she had to improvise a little.

Nina's legs were bound in a frog tie, and then she started on the rigging, Nina wasn't really expecting suspension today, once she was hauled up, the tightness of the rope around her torso, arms and breasts was just that more evident, she even bothered to bind her tail to stop it from squishing around.

Enko brought in a small box of various toys, gently forcing Nina's mouth open as she flipped a harness gag on, not the most extreme gags in her arsenal thankfully, though this one was a ballgag with a small penis-like protrusion to further stuff the mouth, yet without going down the throat.

Seems she had also bought some new vibrating nipple clamps, clover clamps with heavy vibrating weights attached, Nina moaned as she attached them and let them hang, bringing out a remote and twiddling a dial on it, the vibrations were strong, far stronger than their size would suggest they were capable of, it felt amazing to Nina, she shifted her legs around and gagged briefly, drool already starting to escape and drip to the floor.

With Nina barely able to struggle, slowly swinging in the air, Enko got out the unchastity belt's remote, two long sliders as well as a couple dials for various settings. She moved both sliders up about a third of the way and the dildos inside revved to life, waves of pleasure struck Nina's body as she convulsed and squirmed to the best of her ability.

"Oh my." Enko smild to herself, bringing her hand down and touching the outer plate of the belt where the vaginal dildo was buzzing away. "I forgot how strong these were." She looked up at Nina, who had tears forming in her eyes already, making all kinds of muffled noises through her gag. "Oh?" Enko squatted down and brushed her hand over Nina's inner thigh. "You've cum already? Well, I suppose you 'have' had these in you all day."

She returned to her feet and caressed Nina's cheek, moving on to run her hand through her hair. "Well, hope you're ready for this. I'm gonna turn it up to half power in an hour, and full for the last."

A small devilish grin spread over her face as she grabbed a large padel and a whip from the box she brought in. "I'll let you have fun for like, 30 minutes, but seeing you like this just makes me wanna smack the hell out of you. I'm gonna go get changed!" She exclaimed, almost skipping out of the room.

She did eventually get the key, and she can safely say, she did enough to earn it.
