This is the first in a series of HumanxPokemon stories that I hope to write this time featuring everyone's favourite pseudo-legendary dog, Arcanine! Enjoy the chapter!

Kat fell backwards onto the bed, her auburn hair spilling out beneath her. It had been a long day at the Pokémart and she just wanted to crash. Despite the age old saying, the customer was very rarely right and after a week of dealing with what seemed to be the stupidest people in her hometown she was ready for some time off. With the weekend ahead of her free, Kat just wanted to take it easy and spend time with the people she actually liked.

As if on cue, Stripes padded into the room and huffed at her. Stripes was Kat's Arcanine, she'd had him since she was young and he was a Growlithe. As a child Kat couldn't come up with a more inventive name than Stripes and it had stuck.

"What's up Stripey?" Kat called over from her bed and Stripes merely huffed again. Kat sat up

"C'mere buddy." Stripes padded across the room and sank down into his trainer's arms. Kat reveled in his warmth, pressing her face into his mane and sighing deeply.

"I was thinking we could do something this weekend, just the two of us. Maybe we could go out into the Wild Area together?" Stripes pulled away from Kat and licked her face enthusiastically, his tail wagging, Kat giggled.

"Alright! Alright! We like that plan then! It's a date!" She ruffled Stripes' fur and stood up, stretching and moving across the room to the door.

"Tonight I'm taking it easy though. Just a pizza and a movie ok?"

Stripes barked enthusiastically and followed her out of the room.

The apartment they shared wasn't huge but it was big enough for the two of them. Just a girl and her six foot fire dog.

"Alright bud, I'm gonna take a shower. Relaxing starts right now!" Since it was just the two of them in the apartment, Kat didn't hesitate to take off her work shirt on the way to the bathroom, flinging the shirt in the general direction of the washing machine. This was nothing new and Kat continued to strip on her way to the bathroom. By the time she reached the shower, she was only in her panties. She threw her bra playfully at Stripes. It landed on his head and he shook it loose with a huff. Kat laughed at him and closed the bathroom door behind herself.

The evening's plans unfolded just as expected. After her shower, Kat changed into sweatpants and a tank top, put her hair up in a ponytail, planted herself on the sofa and got down to some serious lounging, only moving to collect the pizza. She caught the delivery boy staring at her breasts as she paid him. This wasn't unusual after all, she wasn't wearing a bra and her breasts weren't exactly small. She flicked her hair over her shoulder, winked at the pizza boy and slipped back inside her apartment.

Several hours later, Kat stretched and yawned. Stripes' head was in her lap and she couldn't find anything to watch. As she flicked aimlessly through the channels thinking that she might instead just go to bed, she came across a nature program that focused on wild Arcanine.

"Hey Stripey, it's your friends." he lifted his head slightly, staring intently at the screen. The program was showing a pack of Arcanine socialising with each other and playing with some Growlithe in a rocky plain with geysers occasionally spurting up from the ground.

"They look like they're having fun! It looks a little hot for me but you'd probably feel right at home." Stripes' tail started to wag, thumping against the sofa cushions.

"Wild Arcanine are incredibly sociable" the host of the documentary continued "However, this changes once mating season rolls around." the image changed to two Arcanine circling each other "Male Arcanine prefer to go it alone to look for a suitable mate." The circling Arcanine took turns sniffing each other until one stopped and presented its hindquarters. The male Arcanine seized his opportunity and mounted the female.

"Woah!" Kat gasped "They're very forward!" she looked down at Stripes. His tail had stopped and he'd sat up a little higher, eyes fixed on the TV. Kat looked back at the screen, the program had moved on and was now describing the raising of Growlithe in the wild.

"You ok bud?" Kat looked down at the canine who was still staring intently at the TV "You've never seen mating before huh? Maybe we could find you a girlfriend or something." Kat chuckled and started to stroke Stripes. One hand on his head, one on his belly. She stopped once she felt something weird brush against the hand on his belly, something hot. She glanced down. Stripes' cock was fully exposed and pulsing slightly. The bright red of the member contrasting sharply against the cream fur of his belly, Kat was transfixed by the sight. She couldn't get over just how big it was, easily thirteen inches long.

"Wow Stripey...I didn't realise you were packing heat.." her description wasn't wrong, she could feel the heat radiating off his cock as it hovered above her hand. Stripes huffed to get Kat's attention. She snapped out of her daze and looked down at him. They stared at each other for a few seconds. The TV droned on in the background.

"Is that from...seeing them...mating?" Kat broke the silence. Stripes huffed in agreement. Kat glanced back at his belly, his cock still hovering above her hand. She felt a strange thrill wash over her.

"Stripey…" she gulped "Do you...want to try something?" without waiting for an answer, she lifted her hand and gripped his cock. Her fingers just touched as she wrapped them around him. Kat glanced back down at Stripes' face. He was still looking up at her intently. She felt herself get aroused by the feel of his cock in her hand, her nippes stiffened against the fabric of her tank top, outlining themselves.

Stripes broke eye contact, only to find the hand that had been resting on his head and give it a few quick licks. Kat, feeling herself get wet at the touch of his tongue, took this as consent. She began to move the hand on his cock slightly up and down. Stripes seemed to sigh and resumed licking her hand. Kat got a little braver and began to move her hand faster and over the whole of his length. She felt wetness on her lower hand and looked to see that precum had begun to collect at the tip of his cock, she had unknowingly run her hand over his tip and coated her hand in the fluid, allowing her hand to glide smoothly over his cock. The heat wasn't a problem, it was pleasantly warm like Stripes had always been. Transfixed as she was by her hand sliding smoothly over the dick she was caressing, she didn't notice Stripes stop licking her hand and beginning to sniff around her legs until she felt his nose press between her legs. She gasped slightly and looked down. Stripes had begun to nuzzle gently into her groin sending little stabs of pleasure through her.

"Mmm...it's only fair I guess" Kat mused as she relinquished her grip on Stripes' cock to shimmy her sweatpants down her legs, her dripping pussy meeting the cool air. Stripes had rolled off the sofa and was now standing in front of Kat, his cock bouncing slightly with every move he made.

Her legs freed, Kat sighed softly and spread her thighs apart, allowing her drenched pussy to feel the cool air of the room. She leaned her head back against the back of the sofa and moved her precum coated hand to her clit, teasing it gently. Her breath caught in her throat and she moaned. Stripes sniffed intently at his trainer's thighs as her hand continued to tease her clit.

Kat's eyes shot open as she felt Stripes' tongue against her folds. His rough tongue gave one tentative at her opening before he nudged her hand away and licked her pussy from bottom to top. Kat gasped and placed one hand on Stripes' fluffy head.

"Oh yeah Stripey, that feels good!" she pressed his snout harder against her pussy and he began to lap at her quicker, his tongue pushing through her folds. She began to writhe, gripping both his ears to keep him in place as she grinded against his lapping tongue.

Kat could feel her orgasm building. It welled up deep inside her as she continued to rub her pelvis over Stripes' snout. His nose pressed against her clit and she let out a hoarse yell as she came. Shuddering, she collapsed back onto the sofa, letting the waves of pleasure wash over her. When she had recovered enough, she looked down at Stripes' face giggling.

"That was amazing, Stripey! Who knew you could be so good at that?" Stripes looked back and whined "Oh that's right! I'm so sorry bud, I got caught up in the moment." pushing back sweaty strands of her hair that had come loose from the ponytail and stuck to her face, Kat slid off the sofa next to Stripes, his cock still rock hard and dripping precum onto the floor. She took it in her hand again and began to pump her hand back and forth along his length, stroking his back as she did so. Stripes began to hump slightly into her hand and Kat began to remember the mating pair on the documentary. She wasn't completely satisfied, she realised…

"Stripey." Kat crooned in a sultry voice as she let go of his cock once more. Stripes whined and looked round, his tongue lolling out of his mouth.

"Maybe now is a good time to teach you about mating." Kat turned around and braced herself on all fours, arching her back and sticking her ass up in the air. Stripes barked and next thing Kat knew he was above her, his forelegs either side of her head. She could feel his cock resting against her ass. Kat reached under herself and positioned Stripes' cock against her entrance.

"Ok boy, go slo-fuuuuuuuuuck." Kat moaned in surprise as Stripes pushed his tip into her. The stretching felt good, bordering on pain, but Kat could get used to that. Stripes continued to slide into her pussy, Kat managing to fit inch after inch, her abdomen bulging to accommodate the massive member. She felt her mind being overtaken by pleasure, she couldn't think straight, all she could concentrate on was Stripes' dick filling her up.

She could feel the beginnings of his knot pressing against her pussy. She'd teased him enough that it had begun to inflate and was now resting at her opening. Kat breathed deeply, she'd never been filled like this before. Just as she was beginning to get used to the feeling, she felt Stripes begin to pull out of her.

"Stripeeey" she moaned before Stripes thrust his hip back towards her filling her again and causing her to gasp.

Stripes did start out slow but soon sped up, slapping his knot against his overwhelmed trainer. Kat loved the sensation of being filled over and over again, her eyes rolled into the back of her head as she moaned over and over again. Her hair was flying willy nilly as she was being pounded, the auburn of her har matching perfectly to the Arcanine's fur. She could feel her orgasm building again, a new wave of pleasure washing over her every time she felt his knot slap into her pussy. Suddenly it broke over her, she grabbed onto Stripes' forelegs as she screamed out in pleasure. Her juices coated his cock which only spurred Stripes on, allowing him to plow into her faster and faster.

Kat felt as if her mind would break as her beloved Arcanine slammed into her again and again until finally he hilted himself inside her and with an almighty thrust managed to wedge his knot inside her. It stretched her pussy to breaking point, she didn't have time to focus on this however as Stripes filled her womb with his cum. It rushed into her as he let out a howl and Kat's mind melted again as she came for the third time that evening. The feeling of being stuffed full of cock and cum at the same time was too much and she lost consciousness.

When Kat came too, she found herself lying on the floor with Stripes cuddled up next to her. Sitting up groggily she glanced down at the puddle of cum that had flowed out of her while she was unconscious. Stripes nuzzled into her side and she laughed weakly.

"Well, this weekend might end up being a little more interesting than just a trip to the Wild Area."
