Zack was in a mad dash to get home after preschool. With no busses, he had to make his way on a gravel path through the woods. The uniform he wore was a cheap, blue cloth and the bulkiness of the diaper he wore was obvious through the shorts. He was shy, rarely to speak and had issues controlling his bodily functions which lead to plenty of accidents. This time, by some miracle he was able to hold it in. He hurried on his way with the gravel and autumn leaves crunching beneath his every step. Though his bladder stung and threatened to empty itself, the boy was confident he could hold it in if he just focused. Zack would make it home and use the toilet, and his mom would be so proud. Too tunnel visioned from all of these factors, Zack failed to noticed an older boy step from behind a tree ahead, sticking his leg out.

With the impact of his shins against the older child’s leg, Zack tripped. He scraped forward along the gravel road and the shorts of his uniform tore quite easily. Pushing himself up from the ground, Zack knew it was over. The familiar sense of relief hit him as the steamy liquid gushed from his over strained bladder. Contrasting the cool air, the warm urine flowed wherever it could before being soaked by the thirsty diaper. Its once pillowy texture turned slick and soggy as the diaper grew heavier and swelled in size. The older boy took notice of the yellow line through the freshly ripped hole in Zack’s shorts. Watching it turn blue to indicate wetness, the chubby bully laughed and ripped Zack’s shorts off completely.

“Haha! Look! The loser peed his pants!” The bully shouted, waving the ripped shorts in the air and pointing at Zack’s diaper.

Though there was no audience around, Zack was overwhelmed with embarrassment and frustration of his tormenter. The chubby boy always took pleasure in picking on the shy child. As Zack stood back onto his own feet, he was struck with anger. He wanted to charge at the bully with all the force he could, but could not bring himself to do it. Instead, his eyes welled up with tears which began to run down his face. Zack sniffled his runny nose.

“Aww, don’t cry. Just run on home and I bet mommy will change you!” The bully taunted before running off, the ripped shorts still clutched in his hand.

The little boy stood in place, sobbing to himself. He was finally going to use the toilet like a big kid, but that jerk ruined everything. He was about to start walking home, his shame fully exposed to anyone he’d pass by when a deep voice came from behind him.

“Got yourself a bully problem, I see.” The voice spoke.

Zack turned around and saw that he now stood in front of an Arcanine. The pokemon was massive in comparison to him. The beast stood over him with a coat of tiger like fur and a fluffy white mane. Having never seen a pokemon so large, Zack stumbled back falling onto his butt. He scooted away from the massive fire-type coming into contact with the tree that preciously concealed his bully. Unable to move no further, the young boy trembled as his stomach began to boil with a familiar heat. Zack’s insides groaned and gurgled as his former lunch began to spew from his rear end. The odorous sludge spurted and splattered wherever it could reach inside of his diaper.

“Whew!” The arcanine spoke, fanning a paw in front of his face. “Easy there, kiddo! I’m not gonna hurt you! In fact, I was hoping you could help me… I’d be happy to help you in return.”

The child recognized the big canine's friendly demeanor and got back to his feet. His soiled diaper hung between his legs, defiled in every way imaginable. It still held its shape however, albeit swollen in size. He dusted himself off and looked himself over, thankfully having recieved no scrapes or bruises from his encounter. He then looked back at Arcanine, who stared at the boy with a big smile on his face. Holding a finger to his own mouth, Zack began to think about the pokemon's proposal. He'd do anything to be rid of his bully, but what could a child so small possibly do for a creature so large?

"Well, big guy? What do you think?" Arcanine asked, hoping the child hadn't already forgotten.

Zack was sure of his answer. Hyping himself up for a possible bully-free life, he looked at the fire type with confidence and nodded with a determined expression.

"All right then, it's settled!" Arcanine said joyfully. "Why don't we go somewhere a little more private then?" He added, motioning his head off the side of the path.

Zack walked to the edge of the gravel road, looking at the dry autumn grass that still stood tall. He was hesitant at stepping off the gravel, knowing he wasn't supposed to go off of the road. Arcanine bowed his head forward behind Zack, using his nose to nudge the boy forward from the rear. Perhaps this time, it'd be ok since he wasn't alone? The boy began to step forward off of the trail as his bare legs squished the soggy padding between them. The pair shifted their way through the grass a ways and came to a clear spot where the grass had shortened and a single boulder sat.

"This seems as good a spot as any. Why don't you go have a seat against that rock over there?" Arcanine asked Zack.

Obediently, Zack walked over to the boulder, sitting with his back against it. His filthy diaper squished under his body weight pressing against it. Arcanine followed, sitting in front of the boy. Zack noticed something poking out from between the pokemon's legs. Though it looked nothing like Zack's own, he knew it could only be one thing. The red cock of Arcanine stood fully erect. It was a fat shaft, sitting atop a knot and the head was finished with a pointy tip. Red and fleshy looking, Zack could see veins within the throbbing member. A steady flow of clear precum secreted from its eager tip.

Arcanine gave the child instructions. "Just think of it like a lolipop or something." He finished.

The Arcanine lifted his front paws from the ground, standing them against the boulder. Zack stripped his clothes as advised, leaving only his diaper on. Though it had already served its purpose, there was no telling what other accidents may occur. Having propped himself up, the beast's cock was now right in front of the boy's face. Its fluids were now dribbling onto the child's body. Zack could feel the heat of the fire type radiating from it.

"Go ahead little buddy... just as we went over." The lusty Arcanine urged the boy.

Zack took a breath and began to awkwardly lick at the tip, immediately tasting the bitter and salty precum. It wasn't exactly pleasant to him, but the boy managed to deal with it. Putting his hands on the Arcanine's shaft, he held it like a large baby bottle. Pressing the fleshy head of Arcanine's cock into his mouth, Zack began to slurp away at the tip while using his hands to massage the girthy shaft.

"Ooooh, that's it big guy..." Arcanine murred out.

The touch of the boy was delightful. He clenched his paws and scraped his sharp claws against the surface of the boulder which screeched like nails on a chalk board. Zack had gotten more enthusiastic about his actions, sensing that he was making the pokemon happy. Though he didn't fully grasp what he was doing, he took joy in helping others if he could. Arcanine moaned with pleasure, but to him this was all merely a tease. He needed to come up with a new plan fast, one with enough action to really get him going. He pulled away from Zack, allowing the human a small break and instructing him once more. Zack nodded his head in response to the pokemon's words and Arcanine rolled over onto his back.

Zack climbed up onto the pokemon from his head. Arcanine gave the golden brown rear end of the boy a large sniff and the stench strangely aroused the Arcanine further. Zack rather enjoyed his trek of crawling across the pokemon's belly. The fluffy white mane of Arcanine was soft and warm against his skin, while the orange and black fur was fuzzy left him feeling almost ticklish.

The boy finally reunited with Arcanine's large cock. He took the tip back into his mouth as he had before, but this time he wrapped his arms around the shaft. Embracing the warm member, it now pressed against him. Zack suckled the steadily oozing tip and pumped away at the shaft in his arms. He thrust his soggy diaper back and forth, humping against the cock to satisfy it further. Arcanine couldn't even give the child encouraging words this time around as the sensation was too wonderful. His tongue practically hung from his open mouth as he savored Zack's efforts. The child knew he was doing the right thing, as the beast's body expanded and contracted with every breath and it picked up the pace as he continued. Putting in such work while only being able to breath through his nose was a bit tiring, but Zack had managed to find a comfortable rythm to replace his odd squirming. Just as he started to find a sense of peace of mind during all of this action, his mouth was suddenly full of a new substance. Taken by surprise by the pokemon's orgasm, Zack had a mouth and throat full of cum before he could pull away. The boy coughed, spraying the white substance on himself and Arcanine's cock. The pokemon's member continued its eruption, letting a glob of the thick mess loose onto Zack's face before the boy could let go of it. Now pointing freely in the air, the final ropes of cum fired off into the air, splatting both Zack and Arcanine as they landed.

"Hey there, are you alright buddy?" Arcanine finally asked Zack who was still coughing to clear his throat.

Zack was fine and just needed a moment while the pokemon gently pat him on the back. With his throat clear, Zack could finally breath. His face however was still a mess and he could tell there was still semen in his nose.

"There, there champ. Let's get you cleaned off." Arcanine said as he began to lick the child's face.

The ticklish little human giggled as the big canine's tongue slid across his skin. Though he was covered in drool, it was a much less obvious mess than a load of pokemon cum. The boy got his shirt back on, still missing his pants and was ready to head home.

"Thanks for the help, little buddy. I'll make sure that bully doesn't bother you anymore." Arcanine said. "I'll see you around, kiddo."

Zack waved goodbye and made his way back home. The next day, Zack was walking his usual route home from preschool. The little boy had wet himself right as it was time to leave and was able to change in the restroom, so he was in much less of a hurry this time around. As he approached the same tree from the day before, his pully had stepped out from behind it with a grin on his face.

"Well well, loser. Ready to pee your pants again?" He taunted.

Before he could begin approaching Zack, an orange blur flew over the young preschooler. It landed on the ground with a thud between him and the bully. The prick stood frozen in fear, looking at the large pokemon with eyes full of terror. The might beast loomed over the chunky child with a fierce expression on his face. A moment of silence passed as the Arcanine stared the boy down. The fire type took a deep breath and let forth an ear splitting roar right at the bully. The kid's pants began to darken with wetness as a puddle formed in the gravel beneath him. Gaining control over his limbs, the bully quickly picked himself up and ran off. His cries of terror faded away the further he got. Zack stood beside the furry giant, who was laughing uncontrollably.

"We sure showed him, didn't we?" The Arcanine said, ruffling Zacks hair with his paw.

Zack was giggling with excitement. To see his own bully wet himself and run like a coward was the best thing he'd ever seen. The little boy was so happy, he knew he had to express his gratitude. He stepped before Arcanine who looked down at him. Giving a small bow, the child finally began speak to his new friend.

"T... t-thank you..." Zack stuttered out. "D-d-do you... think we'll b-be able to p...p-play again somet-time?"

Arcanine smile, lowering his head within reach of the boy.

"Of course we can kiddo! We can play any time you want." The pokemon replied as Zack happily began to pat the large beast on the face. "What's your name anyway?"

"Z-zack." The child replied. "Wh-what's your's?"

Arcanine chuckled before replying. "Well, I guess I don't have a name. But you can call me Daddy if you'd like!" Arcanine said with a smile. "Now c'mere, I'll walk you home."

Zack managed to climb onto Daddy's back, and the pair walked through the woods together. Zack never had to make that trek alone again. No longer living in fear of the older bully, his confidence grew and soon found himself able to use the toilet like the other kids. He still however liked to wear diapers when hanging out with his new friend, as Arcanine really enjoyed them.
