"Mm, you're insatiable," Candace groaned as she pulled Katie into a deep, passionate kiss. 
Both Katie and the Captain had clocked out for the day, the both of them taking a couple well-deserved days off from work and intent on spending every minute with each other. The panda and bunny shared an intimate and intense cab ride to Candace's apartment with much groping and molesting of each other all the way there. It was a wonder they managed to make it in the door before their clothes practially flew off.
Katie had felt Candace's thick black cock before but this was the first time outside the job that he'd seen it and wasted no time. Once the door was closed and they were both nude, Katie dropped to his knees and took Candace's cock into his muzzle. He practically worshipped it right then and there, egerly bobbing his head and swirling his tongue in ways that made his superior moan approvingly. Her back was against the front door for support, surprised by the bunny's entusiasm and before long decided to take over.
"Oh, god, I've wanted to do this so long," Candace groaned and gripped Katie's head gently in both paws. Katie was reduced to a drooling, moaning toy as Candace facefucked him hard, pounding his little throat and elliciting little gags now and then among the brief moans of pleasure. His little cocklette was hard and twitching, getting excited by the treatment. Just when he thought he might pass out from the hard throat-fucking, Candace pulled his head down hard and groaned, unloading her heavy balls into Katie's stomach.
"Aaah, swallow it all, bun," she moaned, humping his muzzle a few more times until the flow stopped and Katie pulled his head back. Candace produced a goodly amount and Katie felt the warm fullness in his belly.
"Ahh..." he panted softly, still kneeling and doing a little sexy show for Candace. There was a still a bit of a mouthful of panda cum in his muzzle and he made a lewd show of swallowing the load and giggled when he got the reaction he'd hoped for: Candace's cock jumped to attention right away.
"C'mere, cutie," the Captain growled playfully and pulled Katie into her arms, kissing him passionately while moving towards the living room.
It was fair spacious and a little less decorated than her office, giving the impression of where the panda spent more of her time. But there was a couch in the center and soon Katie was bent over the arm and moaning as Candace lined her slick cocktip up with the bunny's tailhole. There was no foreplay, just the hard thrust that spread katie open and forced a girly squeal of delight from his lips. They rutted like animals, hard and fast and desperate for release. It didn't take long for Katie to cum after earlier and after feeling Candace's thick sack spanking his own over and over he came quickly, letting a single spurt onto his own footpaws. Candace followed suite, groaning and pulling out at the last minute to paint Katie's rump and back with her hot cum before sinking back and sitting down on the floor while the bunny lay slumped over the arm of the couch.
They remained that way for a fair bit, both panting hard. Finally, Candace spoke. "There's... there's a shower in the bedroom," she panted. "Clean yourself up, hun. We've got a week together and I don't want it to go to waste. <3"
It was true and Katie pondered on that as he stepped shakily into the shower and began washing himself off. It had been two weeks since he and his friend Mabel had been evicted from their now-condemed apartment building and only a day after that it had been demolished just after they vacated. Left with nowhere to go, the pair had been sleeping in the precint's tiny boarding quarters that provided little more than a bed and access to the locker rooms. That had worked for a temporary time but they needed a place of their own. And then Mabel went and adopted the three kittens they had arrested. Xia had tamed and trained them easily into a trio of obediant pets that were ready to register themselves as slaves-to-a-good-home on the market but Mabel stepped in to buy them and become a cute, strong bovine gal with three little kittens that loved her milk.
After that, she had managed to land an apartment just big enough for her and the kittens but not big enough for Katie. But he'd been a good sport and didn't hold it against her... but he was still technically a homeless cop. So he'd been crashing in the precinct quarters most nights and spent a night on some couches but Candace was the first to offer her bed. This was quite different from the workplace play they got into at the precints and on the clock, this was very intimate. Katie was a guest in Candace's home and needed to respect and service his benefactor however he can.
Candace knew that as well, something katie found out after exiting the shower with a towel wrapped around his body. There in the bedroom Candace sat, the panda smirking with her legs crossed and wearing a simple dominatrix-like outfit. It mostly consisted of artfully arranged latex straps but included long black elbow gloves and black thigh highs. She'd done a little eye makeup too, making her gaze look even more piercing and commanding. If Katie didn't know any better, she'd have thought this Candace's very skilled impersonation of Xia.
"Come here, hun," she purred and patted the comforter next to her, prompting Katie to sit which the bunny did. "I'd love nothing more than to have you with me, but there are some house rules you'll have to follow. Understand?"
Katie nodded. "Y-Yes, Captain."
Candace chuckled and shook her head. "Katie, in here I'm not your Captain. I'm your Queen. And Queen Candace likes to be entertained." For a moment, Katie was stunned. That is, until he noticed the little twitch in the corner of Candace's muzzle; she was having fun playing this silly game and trying not to spoil it.
Katie nodded. "Yes, my Queen," he said and bowed his head reverentially. "How may I entertain you?"
Candace smiled and stood, holding out her gloved paw which Katie took and was pulled to his feet. "Come with me, my little bunny," she announced in the most dignified voice she could manage, still in her domme outfit of straps and led Katie back to the living room.
What he saw was honestly surprising.
Candace had arranged a bench in front of the couch, set out with seven dildos secured with suction cups and in ascending order of size. From left to right the dildos got long and thicker, the smallest being barely six inches long and an inch thick. The biggest was a full thirteen inches and nearly three inches wide all around with silicon balls at the base. All were coated with lube and ready for use, something that only added to the smile on Candace's lips as she sat on the couch like royalty.
"The Queen wishes to know just how talented your rump is, my dear," she announced and gestured to the dildo bench. "You will start from the smallest and take each one into yourself. You will ride them as long as I say and only move to the next when I give permission. If you succeed, you shall be granted the honor of my bed and tasting your Queen's cock. Fail... well, let's just say you won't want to fail. <3"
With a gulp, Katie let the towel drop and approached the bench. At first it was easy, the first two dildos easily taken and ridden until Candace ordreed him to move up. The third dildo was bigger, an increase in width too streaching his tailhole but with a little work he rode it until Candace told him to move up. By the fourth dildo Katie was a panting little performer, moaning and whimpering as he was stretched wider and wider and penetrated deeper and deeper.
Candace was enjoying the show greatly, ordering Katie to take different positions so she could watch him be penetrated at all angles. As Katie started moaning more she started stroking her throbbing black cock, balls already heavy with cum just waiting to be drained. SHe ordered him to ride the sixth dildo for a long while, forbidding Katie to cum and making him edge all the while. He tried not to beg for mercy, to beg to cum but soon he couldn't help it.
"W-Wanna cum," he whimpered.
"Not yet, bunbun," Candace sang, smiling at the show. "Now take the last one."
The last dildo. Katie wouldn't have been able to take it in so easily without the build-up and was glad for it. He moaned so softly as the broad tip pushed into his tailhole and he slowly eased himself down. It took a lot of work... but he managed to take the full length.
"Sit on it," Candace ordered.
Katie obeyed, a little mewl escaping his muzzle as he did and leaned back on the bench, the bulge of the toy visible on his otherwise flat tummy. "B-Big...!" he gasped, fighting to keep from cumming until allowed.
"Ride it," Candace ordered.
Katie obeyed. It felt so big, so unyeilding as it reached so deep within. The width and length were too much for him, too much abuse of his prostate. His legs went out from under him and he dropped back down, taking the full length and gasping wordlessly as he came, three good spurts shooting from his cock. There was a long silence, punctuated only by Katie's soft panting in his own afterglow. He didn't even realize what he'd done until he noticed Candace standing over him with arms crossed over her breasts.
"So close, so close to completion," she tsked teasingly. "But a Queen's word is law. You have failed andthe punishment must be administered." She stood strong and tall as Katie sat on the huge toy. "I hereby sentance you to be the Queen's cumdumpster for the night!"
Katie couldn't resist, he was too weak. Candace must have been a Dom officer in the past, she was so good with bondage. In a matter of minutes, Katie was bound tight and helpless, his arms and legs bound folded up and making it all but impossible for him to move around. A special harness that included a blindfold and ring gag completed the outfit and effectively forced Katie to lay on the bed with his muzzle open. He was like a rubber-bound bondage toy, perfect for Candace to cuddle, which she did, and fuck. An inflatable plug in his rump prevented that one, however, as Candace pumped it a few times until Katie let out a mewl through his gag.
"There, all set for bedtime," Candace announced and yawned, stripping off her outfit and climbing into bed with Katie. "C'mere, little hunny bunny. The Queen would like to grace you with a little taste of her. <3"
Soon Katie was having his face fucked again, Candace shoving her cock down his throat over and over again until she came some time later, giving Katie a nice bellyful of cum. With a happy sigh, she rolled on her back, laying Katie on top of her with her cock still in his open muzzle. She started to doze off like that, rock hard and Katie able to move just enough to suck his Queen's cock.
"You did quite well today, bun," she yawned and pat his rump approvingly. "We'll try again tomorrow and upgrade you form cumdumpster to Princess. And Princesses just love to be filled. <3"
