A Good Boy
Jackson the german shepherd was a good dog. He was well aware of that―his owners having told him many, many times how good of a dog he was. When he brought back toys that they'd throw in the back yard, when he stayed put even though there was a bowl of delicious food in front of him, when he would give Sir lots of kisses and snuggles―just about whenever he did something that didn't involve barking or biting, he was a good boy.

In fact, he'd been such a good boy that Sir was letting him run free in the dog park for as long as he wanted! It made him so excited that he'd almost knocked Sir over when he was let out of the car.

There were a few other dogs there, but they weren't interested in playing with him, and Sir had stopped throwing his ball, so Jackson, or Jax as he was sometimes called, decided to explore. The whole park had a big fence around it so he wouldn't be able to run off―not that he'd want to―but it ensured his safe return.

There were trees and bushes in the park, so it was still nice and shady even on a hot, sunny day like today.

So he wandered, panting happily as he sniffed around. He could pick up the scent of dozens and dozens of dogs, all over the place, but there was one tree, bigger than the rest, that most of the scents were coming from. That meant he had to pee on it, of course, so it'd be his tree! He knew another dog would pee on it when he was gone, but he could always come back and do it again.

Jax lifted his hind leg and huffed happily as the urine streamed out, only to be startled by a sudden yelp. “Hey! Watch where you're peeing!”

The german shepherd perked up, tail wagging. It was a dog! It was another dog! Only... something was off. This dog talked like Sir, and it stood on two paws instead of four... he could remember seeing some animals like that, when he last went to the vet―they had cats and dogs and all sorts of pets of their own. A dog owning a dog seemed weird to him, but he shook it off.

All he needed to know was that this was a dog! A dog that might play with him! At that moment, the other dog was shaking his urine out of his fur, and he took that as a good moment to sniff under his tail. This also surprised the other dog, but he didn't complain or anything―he just turned around really fast and patted Jax on the head.

“Friendly boy, aren't you?” Jax was very friendly, yep. “I wonder...” The other dog looked around, and Jax could smell that he was nervous. “You wanna play a game, boy?” A game! Jax jumped and spun around and wagged his tail. They were going to play!

At first, this other dog confused him, since all he did was take off his clothes, but as he dropped down to his hands and knees, Jax had an idea of what was coming and it made him [b]very, very[/b] excited, in a special way that he usually only got to be when he was around the girl dogs Sir would bring him to.

The other dog was presenting himself to be mated―tail raised, hole waiting for Jax's cock just like a girl. Sure, this dog was a boy, but he wanted to be mated with and Jax was happy to oblige. It had been a long time since he mated.

That didn't mean he'd lost his touch though. Jax jumped up, paws on the other dog's hips, and taking a moment to find his entrance, slammed in. The dog below him bit down and growled, and Jax could tell he was in pain, but this is what he wanted, so Jax didn't stop.
The german shepherd leaned down, licking across the dog's neck and face, and the dog shuddered, soft huffs and moans escaping his clenched maw. “Good boy...” Oh yes, he was being a good boy! “Good dog, good boy... keep fucking your bitch...”

While he didn't understand all of what was said, Jax knew he was doing a good job and mating with this dog felt good, so so good. His hole was tighter than the other dogs he'd mated with, and he didn't try to pull away or bite him. This dog accepted everything Jax wanted to do.

So he kept thrusting, already his knot starting to pulsate. It wanted in, [b]he[/b] wanted in, and as tight as this other dog's hole may be, it wasn't going to stop Jax. With all his might, he pushed and pulled, ramming his cock into the smaller dog so hard and fast, that he could barely contain himself. One of his paws went around his own cock, stroking it to Jax's movements, which just urged the shepherd on.

Jax wanted to cum, wanted to fill this new bitch with his cum, and he wanted it so bad. With a final, powerful thrust, he managed to squeeze his knot into that tight hole, biting down on the back of the smaller dog's neck as cum spurted and oozed out in thin white strands. He continued to thrust, slower this time, allowing the other dog to calm down, his own cum pooling on the grass below them.

“Good boy... mm... such a good dog..” The other dog praised him and he stood tall and wagged his tail with pride. Sir would be so proud of him when he found out. Maybe he'd even let Jax keep this dog as his bitch. Sure, he was a stand-on-two-legs dog, but he seemed happy under Jax.

Jax lied down on his side, taking the other dog with him, and panted softly, lapping at his cheeks and muzzle. He'd been a good dog too, letting Jax mate with him. A very good dog. 

Sir was calling for Jax now, not that he could get up and run to him. Wanting to alert Sir of where he was, he barked, his voice filled with happiness. His ears twitched at the sound of footprints making their way towards him, and the other dog started to panic. He couldn't go anywhere with Jax's knot inside of him though.

“What the...” Sir stood above them and Jax smiled as his tailed wagged. “Looks like you've got yourself a new friend there, buddy.” Sir knelt down, petting Jax briefly before extending his hand to the other door. “What's your name?” He spoke gently to the other dog, who looked up with a gulp.

“T-Teddy...” Sir smiled and put a hand on Teddy's head, rubbing his fingers through the soft cream fur on his head. 

“Looks like you'll be coming home with us.” Sir spoke in a tone that meant what he said was it, and even if Teddy wanted to leave, there was no way he was getting away. “I've always wondered what it would be like to have one of your kind as a pet.”
