Hound town Axel is an 8-year-old rat cub with a dream. That dream being to bring home the newest games console, the Ninfendo switch. Though his parents didn't trust the internet at all and the local store only had one left in stock. His birthday was nearly 8 months away and there was no way he could get it with what he'd managed to save with his allowance so far. The chubby boy sighed and looked out the window from his room. In nothing but his underwear, he'd been working little odd jobs all summer. From mowing the lawn to helping with chores around the neighborhood. Today was the day he had just one more thing to do, then he could go get his switch. The laundry still needed to be done though, so he was down to his last pair of clean underwear, and he'd worn it overnight already. So he went ahead and got changed without underwear today, he was sure no one would really notice. He didn't want to have to wait any longer and risk someone else showing up and buying the switch before him, who knows how long it'd be till another one showed up. Pulling up a pair of blue shorts and grabbing a red t-shirt, the cub got ready for his day. If everything went well, the little rat boy would have a full month to play games and relax before school started again. Mrs. Darcy, his neighbor, plans to pay him 20 whole dollars for walking her dog today. Heading down the hall and out the door, the boy starts his stroll over to Mrs. Darcy's house. He lived in a little suburban area right near the edge with a park nearby. He was tasked with taking him for a walk to the park and back, it shouldn't take longer than an hour or two. Knocking on the door, the boy waited a few minutes for Mrs. Darcy to answer. An older looking antelope woman answered the door. She was getting a touch too old to make the full walk herself anymore. She smiled and brought out her dog Rex. When the boy agreed to help, he assumed the sweet old lady had a pug or some other small dog. Instead, she brought out a Mastiff hound. 200 lbs of dog and barely shorter than the cub himself. “Take good care of Rex now, he's been very antsy since I haven't been able to take him for walks as much.” Handing the small boy the leash, she smiled and closed the door. Heading down the road, the boy struggled with the leash as first. Rex seemed very excited to go to the park today, it was less like he was walking the dog and more being walked by the dog. The cub didn't know, if the dog decided to suddenly run off, if he'd be able to stop it. Still, today had to go well without incident in order for him to get that switch. After a few minutes, the rat boy started to get a handle on the big dog. He seemed pretty gentle in his stride, just a big gentle giant. Then as they slipped into the park, he sort of got excited. The dog started panting a bit, the boy worried the dog was getting tired. However, the boy didn't notice the dog's length slipping out of its sheath. Its powerful shaft throbbing free, dripping with pre. This dog was very much not fixed, Darcy didn't care for the idea of it. Balls sagging heavy and large behind the pooch as the boy walked the dog. The boy keeping his eyes forward on the front of the dog failed to notice the incredible load brewing within. The dog did seem like it was getting a bit tired. If he came back with the dog all haggard because he was in a rush, Mrs. Darcy might get mad, so maybe a short break was in order. They were in the park now and, the boy, knew of a good resting spot behind some trees and bushes that had some flat ground and shade. Plus it was out of the public eye so usually no one was around. That dog cock throbbed in the air, a little over 8 inches long. A trail of pre-soaking into the soil as the boy and the dog walked over behind the tree. The dog's hips shivered with lust, balls impressive and fat cock twitching in the air with the need to breed. Slowing down a bit, the boy took point, taking the big pup behind the tree and bushes before slipping over a rogue tree root. Falling forward, the boy moaned, shorts pulling back a bit and exposing his small soft boy ass to the open air. The boy let out a pained moan, holding onto his head a little as he started to get up. Only for a little dog slobber to drizzle over his head. The dog standing over him, 200 lbs of dog, kept the boy pinned to the ground. Annoyed, the cub tried to move forward to get away, but the tree was in the way. So instead he tried to move himself back. The dog even started to move forward, that's when the tip of the dog's shaft slipped between the cub's cheeks. Pre had lubed the dog's shaft well, heat kicking off of its mass. The cub's eyes went wide as he felt it approach his back end. He tried to move himself back forward, but the dog in moving forward stepped on the cub's shirt, slamming him to the ground, locking him in place. The dog panted and drooled over the cub as the boy scrambled to try to move out of the way. The throbbing hound cock pushing down between the cub's cheeks with ease until its pointed tip slipped against the boy's tight asshole. The chubby boy clenched his teeth on instinct and his pink rat tail stiffened as the heavy dog leaned forward, laying its full weight on top of the cub, slamming its shaft down into the depths of the boy. The cub grunts and squirms, about to let out a squeak as his face is pressed into the ground. The warmth of that shaft throbbing in the cub's ass as it just adjusts to the boy's tight depths. The dog letting out a relaxed sigh as it idly moves its hips back. It felt like the dog was pulling out, maybe it was an accident and the dog was about to stop. Slam, the dog slapped its balls against the young boy's ass as it slammed back inside the boy with powerful force. The cub yelping as the dog started to properly slam its shaft in and out of the young boy on repeat. The cub squirming under the dog's weight as it panted and idly barked, enjoying the boy's ass. Putting one of its paws down around the boy as it laid back and bred his ass. Heavy dog ball slapping over and over against the rat's boy's soft doughy young ass. His insides clung tightly around that knotted dog cock. Pre slicking up the boy's insides as he struggled and pushed himself against the ground. In the boy's desire to try to pry himself free, all he was managing to do was pleasure the dog further. His soft form jiggly as the full weight of that dog slammed against the cub's body over and over. His own cock starting to tingle all strange. The cub lifting his head up just long enough to let out a high-pitched moan mixed with a yelp. Wasting his chance to get out a good scream. His face slamming back into the dirt as he pushed back. The dog's knot slamming against his backside over and over again. He could feel his asshole starting to stretch as that knot slammed against his virgin asshole. Rex had apparently been going easy so far because he started to kick into gear properly now. The cub, finding himself being shaken and humped about 20 times a second. Letting out warbled moans like he was moaning into a desk fan. In his squirming to get out from under the rapist dog, he'd tugged himself out of his shirt. Once the dog had lost grip on his shirt, the boy found it a lot easier to pull forward. Kicking back, he found the dog standing on his shorts as well. Wiggling his little feet, he grunted and moaned, his cock starting to tingle harder. It felt like he was about to pee or something. The boy grit his teeth and did everything in his power to pull forward, abandoning his shorts. Completely naked, the boy clung against the tree, with Rex all but out of his ass now. The doggy letting out a whine as the tip of its shaft left the cub's ass. The boy relaxing for about half a second, which was just a little too long. The heavy Dog taking the chance to leap on the boy's back properly and slam its heavy cock back into the depths of the cub's ass. Slicked with pre and already thoroughly used, it was easy to slam the entirety of the pups cock back into the cub's depths. With this slamming hit, the boy felt the dog slam into something strange inside him. It felt, really, wonderful. Warmth rushed down through the boy's form as his cock twitched against the tree. A few small ropes of cum, the first the boy had ever shot off, slicked against the side of the tree. The cub letting out a mix of a squeak and a moan. Gritting his teeth as the dog went back to humping at full force, once again. Knot stretching the boy's backside, dog slobber against the back of the boy's neck. Relaxing thanks to the sheer power of his first ever orgasm. The boy's eyes went wide as something massive started to slip into his ass. Clenching down when it was already a little too late. The dog's fat knot slammed down hard and fast, its hips twisting to try to force in its bulbous mass. The cub letting out a heated yelp, hot steamy breath moistening the side of the tree. The boy closed his eyes once again and grit his teeth, a flash of light over the boy and dog as the dog's knot slammed down into the boy's depths. Opening his eyes wide and letting out a girlish moan, the cub felt his second ever orgasm. Rex huffing and yelping as cum gushed out of his heavy feral balls. Warm cum gushing out, filling up the cub's insides, making his little belly swell slightly. Warm dog jizz filling up his body as cum gushed out of his own shaft against the tree, though significantly less than his first, given he didn't have much time to recharge. The cub had all but given up struggling at this point, feeling the dog overflow his insides with heated spunk. The puppers tongue resting on the boy's head, licking him with affection. The boy and the dog were stuck there for about 10 minutes before the dog was able to pull out. Though it was about 30 minutes before the boy was able to pry himself free. His clothes were ruined, cum was leaking from his little ass, and the boy felt like he was going to cry. That's when he found wet wipes, a full change of clothes and some hard candy in some bushes. Wow, what a coincidence, he got himself cleaned up best he could. The hard candy tasted nice at least, and the clothes felt nicer than his old clothes. Heading back, the tears in his eyes slowly cleared up because he'd at least get to buy that new console today. It'd take him a bit to save up for any more games than one, but he figured breath of the mild would be enough for the rest of the summer. Heading back to Mrs. Darcy's house, he brought back her dog and smiled. He'd at least never have to deal with that mutt again. She smiled down at the boy and gave him his $20 for a job well done. “Oh one moment deary, I have one other thing.” Smiling, she came back out from her house holding a box, handing it to the cub. “For doing such a good job, I wanted you to have this. I got it, so little ones like yourself would come over since I get a little lonely, but I'm afraid Rex tends to scare most cubs off.” Yeah, the boy could imagine, he was starting to wonder if he'd be able to sit down when he gets home. Looking in the box, the Rat boy smiled wide and looked back at Mrs. Darcy. “Hey, is this a switch!” She smiled at the boy and the cub looked over all the games that came with it. “I'll only ask that you come by now and then and walk Rex some more from time to time, he came back looking so happy from that walk and my little legs just can't handle it.” The boy froze for a second and had to actually think about it. But looking down at the console, he gulped and reluctantly agreed, heading home. He figured he could just walk the dog in more public area's, but this would be a mistake as he'd find himself dragged into many a back alley or being used on empty streets. Mrs. Darcy went back inside and smiled, looking at her Phone. “I really need to get this fixed, I nearly had a heart attack when the flash went off, I thought the damn thing was off.” The old woman looking at the picture she took of the cub being ruthlessly raped by her dog and smiling.
