Alright, so this is a silly thing that spawned out of a conversation I had with a dear friend Wesku, based on a piece of art he commissioned from MetalFox. Not the type of thing I'm usually into, but I would lie if I said I didn't have a lot of fun writing it! Also thanks to SolipsisticNarcissistic, Sonkenishen , Tempo, Keks , and Kira feedback and editing! The art is drawn by MetalFox and commissioned by Wesku


Cat Augmentation


After learning what his canine boyfirend likes to do at nights when he thinks nobody is around to see, Mittens decides to get him a present to spice up their inter-species relationship.

"So Mitts ... what is this thing?" the white shepherd dog asked as he inspected the contraption that lay before him. Connected to what looked like a leather strap was a black toy which smelled like plastic, but had the unmistakable shape of, well, something that looked a bit like his own member, he noted with surprise.

"It's like an augmentation device. Consider it an early birthday gift, Wags". The black tuxedo cat in front of him just sat there, a lewd grin etched across her muzzle. She was definitely up to something.

Bolt hunkered down, sniffing the so-called birthday gift tentatively, still confuzzled. He had received presents before from his person, although they were typically something edible and delicious. Or at the very least, something he could chew. This looked like neither of those things. An augmentation? Was this some kind of sex thing? In that case, why did he need it?

"That's really nice of you Mittens, but I already have one of those", he said as politely he could, pawing the black rubber toy warily. In front of him, the feline chuckled. The crafty cat definitely had some weird idea and was now waiting for him to figure it out.

"Well, you're not really the one who will be using it. I am"

Growing even more confuzzled, Bolt's gaze wandered between the cat and the strange device on the floor. "Then how is it a gift to me?" he asked impatiently, head tilted, ears perked.

"Oh, you'll find out." Mittens replied, still smiling, seemingly amused with the situation. Behind him, his tail started to wag slowly and impatiently, an indication of his growing irritation with the tantalizing cat's cryptic and yet suggestive comments, but also betraying his subtle sense of excited anticipation. Just what was she planning?

"How... how does it work?"

She picked up the rubber toy and displayed it in front of him. "Really now, Wags... I thought you've had enough experience with Mr Carrot to figure out where this is going." She held the tip in front of Bolt's nose, causing the canine to winkle his nose and cross his eyes as he focused on the strange object. "It's not like I haven't seen you cheating on me with that rubber carrot of yours.", the feline continued.

His ears perked up in sudden shock. How could she know!? How the cat had managed to see him doing those things with Mr Carrot was beyond him. He was always so vigilant!

"Don't worry Bolty." The cat smiled again, but more kindly this time. "There's nothing wrong with a little experimenting. And I got this thing thinking that you might want to try something new".

"So you saw me, huh?" Bolt muttered quietly, his ears drooping slightly as a as a wave of nauseating shame crashed over him. "I didn't want you to see me like that... doing that" He lowered his head ,looking at his paws and doing everything possible to avoid eye contact with the cat. "How do you even know about my top-secret activities to begin with?"

"Well, sometimes you just disappear downstairs to be alone, so I knew something was up. Besides, you sorta make a lot of noise...

"Oh boy..." the white canine blushed even more.

"Ah, don't worry about it Wags." Mittens draped a comforting paw over Bolt's shoulder. "It's not like I mind it. Really! It's almost kind of cute you know. So why not try a little role reversal?"

"I'm still not sure about this..." he whispered, still evading eye contact, still blushing. He felt the need to make up something. Lie. Back away from it all. But now that he knew what the rubbery thing was used for, he couldn't deny that the whole idea was strangely... intriguing.

"Well, even if you're still trying to make your mind up, the rest of your body already seems to have decided" She nodded towards Bolt's red tip which was already peeking out of his sheath. Bolt didn't think his cheeks could get any hotter, but they did, and he cursed his pristine white fur its ineffectivety at hiding his reddening cheeks and ears. He couldn't deny it though; under his slender belly, he could feel his slick canine shaft pulse within its stretched home, completely outside his will and control, to his terrible chagrin. Frustrated with his own member conspiring against him, and even for frustrated with the smirk that started to grow on Mittens' lips. He let out a sigh. Was there any point in trying to hold on to whatever shred of pride he had left?

Noticing his embarrassment, the feline moved closer to Bolt, hugging his big fluffy body. "We're not doing anything you don't want to, you know that", she said, even going as far as to delivering a slight lick unto his cheek. Bolt wasn't much for affectionate licking, so Mittens despite being a cat had to compensate for it. Appreciating the concern, the white canines' ears rose just slightly. "I'm still not sure about this, Mitts"

In surprise, he noticed that the cat's mischievous paw had started to travel from his shoulder along his blank towards his well-defined hindquarters. Bolt shivered a bit, feeling a tad uncomfortable. Having his feline girlfriend caressing his furry butt, that intimate part of his body that nobody had ever been close to before. Well with the exception of Mr Carrot, he reminded himself.

Returning his gaze to the strange looking device, he couldn't deny that the rubber thing, which was shaped a bit like his own member, looked pretty interesting, and he had a pretty good idea where it would be heading. He wasn't sure how it would work out, or how it would feel inside of him, but he assumed that it would attach itself to Mittens and augment her, giving her new abilities she didn't have before. Sort of like when he was augmented to have superpowers. When thinking about those abilities, his disobedient cock grew even more. Recognizing his defeat, the former superdog growled quietly; "Fine, cat." He looked up at Mittens. "We'll do what you want".

"Au contraire, Wags. We're doing what you want, what you've wanted all along.", she said in a tone which sounded a little more patronizing than Bolt felt was necessary.

"We're just trying it" Bolt retorted. "Like you said ... experimenting."

"Just like that, Wags! Like you experimenting with Mr Carrot"

"You're not gonna stop mentioning that, are you?"

"Nah, you're gonna be hearing about that for some time to come. Now turn around, Wags.".

"Why?" Bolt replied.

"Just do it"

Bolt did as told, turning around until his tail was positioned in Mittens direction. The whole thing felt a bit weird, redoncules even. While his ears was lowered in embarrassment, the rest of his body shivered in anticipation, knowing exactly what to come. As if by instinct, he raised his tail just a bit. Enough to expose his virgin hole to the Mittens, the one intimate part of his body the cat had yet to explore.

He looked over his shoulder, and he began to catch the familiar scent of the cat, who became steadily more aroused just by glimpsing under his tail. He wasn't the only one with a slightly skewed sexuality, he thought to himself. Suddenly, he felt something wet and warm against that sensitive spot which made him almost jump in surprise.

"What ... what are you doing!?" He hissed, his voice breaking into a slight falsetto. "What are you doing!? You degenerated creature of" he stopped in his words as the small but strong feline tongue slided into his tight behind. The feline's intrusion into him sent a wave of unexpected pleasure through his entire body causing his back arch his back and fold his ears back in reaction to the new sensations. Another wave of pleasure rushed through him as the wet tongue pressed against his prostate, and he involuntarily moaned, spontaneously spreading his stance and splaying his paws. Whatever the cat was doing, it felt amazing! He didn't know his body could produce such strong feelings. "Whatever you're doing Mittens, please just ... keep it up" he managed to pant out.

Mittens couldn't reply, even if she wanted to, with her tongue so deep in her boyfriends furry behind. In front of her, the discombobulated dog was alternating between blissful moaning and attempting to formulate sentences. "Mittens ... I, yes... this, this is totally awesome!" he panted, tongue lolled out.

This was certainly an unusual activity, nothing they've ever tried before, but Mittens enjoyed rimming the white shepherd more than she thought she would, enjoying both his tight body clenching and massaging around her invading tongue and even more the feeling of being in complete and utter control of the big dog, capable of deliver waves of pleasure making his powerful frame quake and shudder involuntarily. She had heard that a little tail licking is a good way of easing someone up before trying something bigger, and she wanted Bolt's first time to be as pleasurable as it could get. Paws on each side of his firm furry rump, she spread his cheeks aside a bit and pushed her strong feline tongue deeper inside the dumbfounded Bolt, and another moan subsequently escaped from him.

Meanwhile, Bolt found himself in heaven, enjoying wave and wave of overwhelming sensation with each lick from behind. He bowed his head between his front legs, catching a glimpse of the black cat, and a view of his now fully erected member as well, which twitched happily under his belly with her firm, steady licks. He was already rock hard and dripping, his red member almost completely unsheathed with the exception of the knot. He suddenly felt a paw on that red length, caressing it slowly up and down. Mittens had one of her arms drape over Bolt's rump holding her tightly to him, as his other paw was reaching underneath him, rubbing the growing red length. Pleasured in two ways at the same time, he knew he wouldn't last long. His penis was throbbing with the cat's rhythmic licks, squirting precum both on her small paws and the creamy white fur of his belly.

Closing his eyes, he could feel something build up, the unmistakable feeling of his climax approaching. "Mittens, wait, ... I'm gonna" but his voice hiked up as it was too late. As he clenched tightly around Mittens slippery tongue inside of him, his red canid member jumped once, twice, and finally began to spurt rope after rope of thick canine cum, plastering his belly, Mittens' paw and his own nose. Painting his black nose with his white sticky seed, he felt like he would collapse into a sticky, furry pile, taking the cat's tongue with him. Instead he panted as pleasant warmth began to cascade through his limbs towards the floor, and as the cat finally pulled her tongue out of the sexy white shepherd's tailhole with a loud slurp.

"Ouch! Let me know if you're gonna mangle my tongue like that again".

"I'm sorry about that. I can't control it. It was just so .. powerful" he panted, his nose still sticky.

"Something tells me you liked it though"

"I'm not gonna deny that I did..." He licked some of his cum away from his nose. "I seemed to have generated a lot of this white liquid too".

"Tell me about it..:" said Mittens, admiring the slimy state of her paws. She then took one of her pads digits and smeared some of it under Bolt's tail. When Bolt looked over his shoulder with an inquisitive expression, she just answered "Lubrication. We're not done, yet you know".

She had almost completely forgotten about the strap-on, which was still lying on the floor beside her. She picked up the device, smearing some more of Bolt's sticky goo on it, then turned to the white shepherd; "You ready for what's next?". Bolt just looked at her for a bit, As if reevaluating the situation, then nodded. "Alright, then just stand still" Mittens ordered. Bolt, having learnt that following the cat's instructions often lead to great things, did just that. Behind him, the cat in question was in the process of trying to figure out how best to undertake the complex task that laid ahead of her. Strangely, the strap-on she had ordered didn't come with any instructions for inter-species humping, but she was quite confident that doggy-style would be the easiest way of doing it.

Bolt, however, was about three times her size, and it became apparent that she would need something to stand on. "Hold on" she said. After a few minutes, she came back, now pushing a footstoll with her which she placed behind him. "What's going on?" Bolt looked over his shoulder with a curious expression.

"Patience. Don't look while I'm taking it on". Rolling his eyes discreetly, Bolt stopped looking over his shoulder. Behind him, the cat had somehow taking on the device and and was now mounting him with her small paws on his powerful hindquarters. He still wasn't quite sure how it all worked, only that it...

*poke*

Once again, the sensation of something poking against his entrance surprised his body.

*another poke*

The touch felt almost electric, and almost frightening.

"Is ... is it going to hurt?" He asked looking over his shoulder. "Don't worry, we'll take it slow" Mittens answered.

She pushed the black rubbery point forward, and it grinded between the white dog's furry cheeks and sliding over the soft, velvety skin of his tailhole. Trying to improve her aiming, Mittens humped against him again, this time hitting her target, sliding in just slightly, causing the delicate canine to gasp in pleasure. "How are you doing down there", she asked, looking down at powerful shepherd below her.

Bolt was panting, not quite able to focus anything else on the tip teasing his entrance. Every fiber of his being was craving for that thing to be pushed deeper inside his body, and to his surprise, he find himself pushing back against the cat, wanting as much of it as possible inside of him. "Please just ... feel free to proceed" he whined.

With each paw on Bolt's powerful whist for increased stamina, Mittens wasn't going to object. Instead, she retracted the rubbery cock back a bit, until the tip was almost outside again, and then thrusted forward, sinking a bit deeper this time. Bolt yelped in surprise, closing his eyes with a strained expression. The rubbery dildo was now half-way into his tight tunnel, stretching his tailhole wider than what he was used to, and it hurt a bit.

Lowering herself, she caressed his side. "Are you okay, Bolty?" He nodded. "Do you want me to continue?" Another nod.

Deciding to proceed a bit slower to give her boyfriend time to adjust, Mittens pushed deeper into Bolt until the fake rubbery knot of the black dildo was bumping against the lips of his hole. As the toy was slowly sliding into him, his own cum from earlier was being forced out, making the insertion sticky and easy. Below her, she could see her canine boyfriend breathing slowly, trying to cope with the gradual insertion. His eyes were closed and his penis, once again, rock hard. In fact, and to his embarrassment, it was harder than it had ever been before. Even though he had just recently cummed. The slight pain from Mitten's thrust was almost completely gone, and had been replaced by a warm feeling of pleasure which was spreading from his prostate through his body, as well as a burning desire for more. The whole thing felt strangely natural. "Please continue" he whined so slightly that Mittens could just barely hear him.

Smiling at the submissive cuteness, the cat pushed It deeper, then gently retracted, and repeated the process. With the rubbery dildo sliding in and out of the dog, each thrust generating a moan from Bolt, the cat was definitely enjoying herself as well. Holding his powerful frame below her, which quaked and shudder in pleasure, it didn't take long until she picked up the pace, wondering what strange instincts in her served to make it all feel so natural.

Bolt wondered the same about his situation as he felt the force of the rubbery toy sliding in and out of him. He spread his back legs a bit, lifting his tail a little higher, giving the augmentation device better access. He almost couldn't believe it, he was now being humped doggy-style by Mittens with all the force her smaller body could master, and he loved it. Once again the handsome canine found himself panting and moaning uncontrollably, enjoying the sensation of having the fake cock slide in and out of his body. He let out a high-pitched, cute whine as it rubbed against his prostate. The pleasure she gave to him was indescribable. "This... this is way better than Mr Carrot!" Whatever embarrassment he felt before was gone. How could something that felt so incredibly awesome be wrong?

Eyes crossed, tongue hanging out and with a silly expression on his face, he could feel another orgasm creep closer. With the last powers her exhausted body could master, Mittens forced the entire length inside his body for the last time. He howled out in intense pleasure, his white ears folding back against his head, and the toes on his paws curling in pleasure. Climax struck him, starting not from his member but the pleasure radiated by the toy deep inside of his tight body. His tailhole closing behind the toy's fake rubbery knot, he came paws free with the intense orgasm rushing through his powerful body and his member throbbing and twitching his white sticky goo all over the floor. Without as much as touching himself, Bolt had just experienced the most violent orgasm of his life, and now he felt too weak to even stay on all fours. The two animals collapsed upon each other, panting in union.

...

Ten minutes passed before any of the two animals said anything. "So what did you think about your birthday gift, Wags?

-"It was... acceptable". Bolt was still feeling the pleasant afterglow from the intense climax. He was laying on his side on the cold floor, and above him, Mittens was laying over his whist with the rubber cock still lodged inside of him. "Did you manage to, you know, finish too?" he asked looking at the cat who was laying comfortably over his lean flank.

"Somehow, I think I did. Should I like ... pull it out?"

"I think so." Bolt actually wouldn't have minded having the strange device inside of him for just a bit more, but he was also getting drowsy and the floor started to feel uncomfortable. He didn't want the humans to come home and see them like this either, so it was probably for the best.

With a plop, she pulled the device out from his abused behind which was still a bit sticky with cum and saliva left there from earlier. Bolt stood up, bowed forward and started stretching his slender body, as he always did after a good nap. Walking up to Mittens, he decided to inspect the toy one last time. "You know, it felt bigger than it looks", he commented.

Mittens snickered. "Maybe I should have gone for the jumbo sized one".

  • "This one is just fine, thanks". He stretched again and started trotting towards his dog bed, which had a mattress which was big enough for the both of them, and which they sometimes shared. The small cat followed. He jumped into the bed, circling it three times before lying down with his head on his crossed paws. After lovingly admiring her beautiful white shepherd for a few seconds, Mittens joined, jumping down beside him.

Her voice suddenly broke the silence. "What about males?"

"What do you mean?" His ears perked up.

"Well, do you think you'd want to do something similar with a real male dog? With you on the bottom I mean?"

"Well ... it's not like I've never thought about it" His cheeks were heating up for what felt like the hundredth time that day. Why was the cat suddenly so keen on interrogating him?

"I think I've seen you eyeing that husky in the park, what's his name...Max?"

"That's preposterous! Mittens... " he turned to her "I wouldn't cheat on you. You know that." In his eyes were nothing but earnest honesty.

"I know that, Wags. With the exception of Mr Carrot of course".

"That one is getting really old..." he muttered. "Besides", he added, "Max smells." His eyelids were getting really heavy so he turned around, dropping a heavy paw on her and pulling her closer to his strong furry chest. "Well, if you're done with your interrogation, I'd love to get some sleep now.

"Goodnight, Wags"

"Night, Mitts".

"Oh and Bolt...?"

"Mhm?" He opened one eye.

"Should you ever like, feel submissive again, you just have to let me know."

"We'll see about that, cat.".

She chuckled to herself and buried her face in his soft chest fur. A few seconds later, they were both fast asleep.
