It was weird, but it worked

You hated to admit it, but after three days of a Chloe-controlled Kim taking charge to satisfy your physical needs, you felt an immediate turn in your relationship for the better. Kim noticed it too, as to her, the multitasking of her being able to talk or listen to things on her headphones while Chloe used her body to play with you left extra time for you two to connect on a personal level again for all things unrelated to your physical frustrations.

Your relationship troubles were solved by a scheming slime girl. It drove you a little mad that you knew Chloe was just using Kim and your relationship as a way for her to butt in on faking a relationship with you as well, but the alternatives weren't fantastic either.

Kim actually started looking forward to these little sessions, and started buying audiobooks in anticipation for them. With all the exercise Chloe put her through where she didn't have to lift a finger herself, she was getting yet another benefit that only served to strengthen her acceptance of the agreement. After a late shift at work when you finally came home, Kim was already scrolling through her phone, searching for the next story she wanted to start.

"Hey there tiger, you look like you could use a little downtime." Kim winked at you as she tapped on her phone, before donning her noise canceling headset. That was the cue for Chloe to take charge, to let Kim drift off into her music or stories for the night while Chloe took charge of her motor functions, blocked any signal from her eyes, numbed her body, and occasionally took over Kim's mouth when she wasn't using it to chat on the phone with friends in this paralyzed state. Soon, the telltale smile of Chloe taking charge spread across Kim's lips, while her hips sashayed back and forth.

"She really wants to just drift away so easily now, huh? She doesn't want anything at all to do with me in bed?" You frowned as Kim's body was already getting to work removing her shirt, tugging her loose garments up and over her head.

"Aww, don't feel too bad, Logan. I'm here to make up for that deficiency, you don't need to worry about that!" Chloe's inflections and mannerisms were always clearly on display with the headphone-clad body before you, as she made no attempt to disguise herself as Kim when like this, despite having the body. "She is almost addicted to being able to just fade away in her head, to learn and daydream with such vividness while I'm in charge... I bet she'd be happy to go a whole day like this. A whole weekend, maybe!"

You frowned a little, but as Kim's body began showing more and more skin, your cock sprang to life, right on schedule. You couldn't help that your body responded so well to Kim being controlled to behave like this, knowing it wasn't really Kim's doing.

"Yeah, I know... but still. It's something that I thought at least she'd want to be a part of. Like... a threesome of sorts? Where she's paying attention but you're still in control?"

Kim's mouth grinned wider as her bra tumbled away from her body. "I'll put in a good word, perhaps. Maybe I'm just too good at satisfying her when you're away at work, after all she does get to enjoy a bit of playtime of her own. We do all sorts of stuff she's never tried before!"

You rolled your eyes, now slipping out of your own shirt and pants, down to your boxers. Mixed emotions in your head changed nothing about the state of what was in your pants. "Great, she's so lucky." Chloe immediately picked up on the sarcasm, and briefly frowned, before an idea struck her.

"How about we do something she's never tried with you, then? I won't tell if you won't..." Seeing Kim's face twist into an expression of mischief for something that was going to happen to her own body was confusing, but incredible in its own right. Not to mention, you had an inkling of where this was going...

Chloe slid her skirt down, and then turned around toward you, pointing her ass right at you as her head looked back over her shoulder, seductively. "I believe she's always said this was off-limits, but she doesn't have to know." The slimegirl wriggled the ass of her host at you, back and forth, with no resistance from an non-participatory Kim.

This got your attention, and your dick became rock hard at the thought. Chloe was inviting you to do something Kim had forbidden, and she was willing to keep it secret? If anyone could hide all the evidence, it would be the slimegirl residing in Kim's body, you supposed. You slid down your boxers and then grasped Kim's hips on either side, hesitating for a moment. Kim's head gave a nod and licked her lips.

You carefully spread Kim's cheeks, placing your member right at her asshole. Again, no sign of resistance from Kim. The threat of breaking this rule and not getting caught almost pushed you over the edge then and there, but you had to at least go through with the deed first if you were to actually be a rule breaker!

And so, you pushed, hard, to enter Kim's asshole. Kim's face contorted into a mixture of pain, confusion, and arousal, as Chloe was clearly enjoying it but she was getting mixed messages from her body. You thought about getting caught, the idea that you could be forceful enough with a Chloe-controlled Kim that Kim would be brought back into the fore of consciousness and would know precisely what you and Chloe were up to. Maybe that was what made the activity even more exciting... you were barely inside her, she was so tight! Lubrication wasn't an issue, however, since you could feel Chloe's cool slime rush to assist in the process. Another concession: Chloe's slime was incredible. The slime served as a sex aid, cleaned Kim's body, kept her healthy, eliminated pain and unease, served as birth control... Chloe removed a lot of variables that rarely worked in your favor when it came to having sex with Kim.

Eventually, with a forceful pop, you pushed your dick's full width past the tip into her asshole, and Chloe rested her hands on a nearby wall, moaning in pure ecstasy. She delightedly tugged and pushed at you, encouraging you to continue while she remained bent over. You kept a firm grip on Kim's hips as you pumped in and out of her, feeling amazing when you were fully inside her tight hole in a way you never imagined! Your hands fumbled around, gripping all over Kim's sweaty body, gliding along her stomach and breasts while you pushed in and out of her.

"Logan, yes! YES!" Kim's voice cried out, although you knew it was Chloe in command still as her borrowed body shuddered under all the stimulation, yet still leaving Kim blissfully unaware of what you were doing to break your agreements with her. "This is amazing! I've never felt so alive! Let's kick it up a notch!"

You grunted, still pumping in and out with reckless abandon, feeling ready to explode at any point. Hearing the words "kick it up a notch" from Chloe always worried you, though. That was a roll of the dice, where either she was going to do something incredible or regrettable in the near future, but either way it was going to no doubt push you over the edge, whatever it was.
