A man and his dog watched a boy shooting hoops by himself. They were far enough away to not be noticed but close enough to know that the boy was alone. The unbridled energy as he moved around the court, dribbling and tossing the ball was impressive. It wouldn't been even more so if the boy was coordinated enough to not let the ball get away. But that didn't seem to detour him, breathlessly laughing as the ball hit the rim and rolled away. The boy carelessly ran after the ball as it rolled right next to the man and his dog. With the ball close, the large black dog stood up, sniffing at the rubber. As the boy got closer, the dog looked up and nuzzled the boy's thigh and moved up to his crotch. The boy chuckled nervously as he playfully pushed the dog's head away.
"He sure is friendly," Stiles said. "What's his name?"
"Derek," the man answered. "He's very friendly. He's a good dog."
"Wish I had a dog. But my dad says it's too much responsibility for me."
The boy reached over and scratched behind the dog's ear. Stretching forward, Derek rammed his snout back into the boy's crotch, causing Stiles to blush as he gently pushed the dog away again. A wet spot was visible on the crotch from the wet nose.
"Like I said, Derek is very friendly," the man smirked. "I think he likes boys more than other dogs." Derek moved back again. "He seems to like you a lot."
Stiles was a bit confused, not knowing what the man meant about the dog liking boys more than dogs, but a wet nose to the crotch made him lose his train of thought.
"Come here, Derek," the man snapped his fingers and the big dog obediently trotted over. "Stop bothering the boy. He doesn't want you sniffing around his balls."
Something about how casually the man said 'balls' made alarm bells ring for Stiles. The only time he had heard people refer to that part of his body like that was the criminals locked up at the sheriff's department. Hearing that word kinda existed him, mostly because of how casually the man had said it.
"He's not bothering me," he said softly.
"You don't mind?"
Stiles glanced at the dog before shrugging. "It's not like he's going to bite it off." He smiled when he heard the man laughing, hoping he came off as nonchalant.
As if following a command, Derek went back to the boy and pressed his nose back into the boy's crotch. It brushed against the growing bulge in the boy's shorts making Stiles gasp.
"Why does he keep doing that?" Stiles asked.
"Doing what?"
"Sniffing my dick," the boy blurted out.
"That's what dogs do. Haven't you seen dogs do that before?" Stiles shook his head. "He wants to play with you. I bet he can be your friend if you let him. He's a good dog and really likes boys."
"Huh?" Stiles couldn't focus on that last part since Derek licked the small tent. "I'd like to be his friend," he whispered.
"Maybe you want to go to my place and see if he wants to be your friend. Let's go before it gets too dark."

Hours later, Stiles was drained, like all his energy had been sucked out. He knew that it was basically the opposite, as he felt the man's cock started to get soft inside him. Panting softly, he laid face down, trying to think. The man, who he found out was a neighbor named Peter, traced his fingers over the boy's back. They moved down the ridge of Stiles's spine, running across the many moles the boy had. Eventually, Peter landed on his prize, fingertips brushing against the small ass to rub his leaking cum back into the stretched hole. Stiles was able to turn his head slightly and saw Derek move closer. The humans were both are exhausted from all the fun they had.
"It's so late," Stiles could barely get out, too tired to care. "My dad is probably really worried. But you feel so good inside my butt."
Peter smiled in the darkness, feeling the kid's once tight hole as it struggled to close in such a short time. The boy had been so naive, not knowing that the man used his dog so many times before to lore boys into his clutches. But Stiles was different, more eager to play than the others. And Peter didn't even need to threaten or drug him to get him just how he wanted. Looking over, he saw his big black dog at the side of his bed, Derek's snout twitching from all the smells. The dog growled as he inhaled the strong odor of sex, his fangs bared as his tongue poked out the side of his mouth.
A dark smirk crossed Peter's face as he saw his dog's red cock start to peek out of its sheath. "I know I said you can be Derek's friend. I think he's very excited to be your friend, Stiles."
Stiles was so out of it, he grinned as he started petting Derek's head, the growls changing to show off his lust. Peter moved back from the boy, positing him to receive the dog's cock. The boy's hole was stretched wide, streaks of cum leading deeper inside. Derek mounted quickly, thrusting his powerful canine cock. The first few missed and hit Stiles's ass cheeks but he was quickly able to find the target. When it hit dead center, Stiles made a surprised noise as the pointed cock went in. Once Derek was fully inside, he stopped for a second, quivering slightly at the pleasure. That small pause was the only break the poor boy got as Derek pounded into him with power and speed. His young body being rammed by the dog, no mercy was shown as Derek fucked. The only time it did slow down was when the dog's knot started to form, blocking it's way forward. From the force of each thrust, the doggy cock tried to go further inside the already stretched hole.
"What-?" He was able to get out before his mouth opened wide in a silent wail.
Peter quickly covering the boy's face with a pillow in case he got too loud. The cock was both longer and harder than the man's, Stiles's body trembled as his body was forced to submit.
"It's his knot," Peter informed the boy. "I told you he loves little boys."
The boy's cries eventually died as they turned into little whimpers and then to soft moans. Peter lifted the pillow to see the glazed expression on Stiles's face, panting like a bitch in heat. A confused look took over as he instinctually grasped his dick, a familiar pressure building inside. Not being able to hold it anymore, Stiles let go and pissed himself. He felt relief and relaxed, the dog sensing the opportunity pounded harder, lifting the boy a few inches to get into a better position.
"It hurts," Stiles whimpered, his cheeks wet from his tears.
Derek readied himself, his drool dripping onto the boy's pale skin as they both panted. Pushing forward, he desperately tried to push his growing knot into Stiles's still tight hole. For a second, it seemed like Derek had met an impossible barrier but then he jerked back and slammed forward again. The moment the knot pushed through both boy and dog froze. To Stiles it felt like there was a tennis ball being shoved inside, he'd never experienced something like that. Slowly the knot moved inside him more, making the young boy feel conflicting things as the knot painfully stretched him even further and the increasing pressure on his budding prostate. Stiles's breath grew rapid as he tried to figure out what he was feeling, each sensation overlapping and trying to dominate. It didn't take long before he felt the knot start to expand.
"It feels so big in me," Stiles panted, still not knowing if he liked it or not. "I feel I'm going to explode," his voice turned to panic.
Peter grinned, he knew what the boy was feeling, usually the one taking his dog's knot. He comforted the boy as best as he could, knowing how it felt to have something the size of a baseball inside. With the knot not able to get any bigger, Derek growled loudly confirming that they were locked together.
"Ohhhh G-!" Stiles shrieked, as Derek's doggy cum began to flood into him.
The boy's eyes glazed over again, his tongue hanging out of his mouth and a line of drool falling down. His slim stomach had bulged out a bit from the knot but with the big load it was even more inflated.
Without warning, Derek dismounted. Stiles's body couldn't move as he gasped in pain. Peter had to move quickly and lift the boy's body to follow the dog or Stiles would've been injured more than necessary. Realizing that he couldn't move away, Derek stopped, the two of them ass to ass as the dog finished filling up the little boy. Being filled like that made Stiles cry out, feeling the hot load spill into him. With a comforting touch, Peter knew he had a new plaything for Derek.
