Besides the usual woe-is-me stuff like wanting to grow up and do everything the adults did, there weren't many things Tello wanted from the world when he was a kid. His family was large and nice, he didn't mind living out in the country, and there was always something for him to do every day; whether it was listening to Grandma tell another fascinating story about Japan or bending over so his dad could rail him behind the horse stable, Tello found he was rarely bored with life. 

Being a kid was great! He knew few other kids, and none of them seemed to take kindly to Tello’s ass in their face, which was unfortunate since Tello really didn't know how else you were supposed to play with others. Action figures and races weren't all that interesting to him. You can pretend to be Superman and run around all crazy if you want, but he's not going home until he gets a taste of your cock. For that reason, his friends were mainly the other members of his family. His older brother, seemingly endless cousins, aunts and uncles who couldn't seem to keep their paws to themselves, and especially his dad, who seemed to spend the most time with him. Other kids would perhaps learn how to start a fire or build a treehouse. Tello was taught how to eat ass and stick things in his dick.

"A-ah... Not too quickly, now." Tello's father, Soh, panted as his son slid his finger further into his fat cockhole, the whole thing slick with cum after having just fucked Tello twice in a row. "My urethra may be stretchy, but that doesn't mean you can go hog wild. You've got to let it get used to being filled up."

"Okay." Tello hummed. He was enthralled; playing with his dad's dick was probably the best way to spend an evening. His father's stretchy, dirty foreskin was incredibly fun to mess around with, and seeing his index finger disappear into it was fascinating. He wanted to see how far he could go. "Can I try fingering my dick too?"

"If you'd like. I think it might be a bit too small for your fingers, though." His dad moved his foot over to toe Tello's crotch, lightly rubbing the boy's tiny 10-year old cock. "You certainly are a late bloomer. Most of your cousins are already able to fuck each other."

"Yeah, well, it's like Aunt Cerisa says. 'You don't need a big penis to have a good time', or whatever." Tello pulled his finger out and sniffed it a bit before tasting the leftover cum he had gathered. It tasted slightly of piss, and suddenly he was feeling a bit thirsty. "Could you pee on me again?"

"You're certainly in a nasty little mood, aren't you?" Soh ruffled the boy's hair. "I suppose I COULD pee on you... But you'd have to do something for me in return."

Tello frowned. As much as he loved his dad, he hated the suspense of these 'games' they'd play. Soh was always getting him to try new things, much to the excitement of the rest of the family, and it always made Tello feel a bit nervous having his ass on display to everyone. "...What do you wanna do?"

"I've been thinking... Max has been awful pent up since Maxine got pregnant and had her litter. The poor dog's been humping almost anything in sight. I bet he'd love having a nice tight hole to fuck, don't you agree?"

Tello was so surprised that he almost jumped up. "You can fuck dogs!?"

"Ha! Of course you can. This old boy's had its fair share of bitch pussy." Soh tapped the tip of his aching cock. "And my ass has seen better days, too. You're a tough boy, though. I think you're old enough to try taking your first knot."

"Wow..." Tello's eyes sparkled as he thought of getting down for Max to use him. He loved playing with the big labrador, and always watched him rut bitches with avid fascination. He couldn't believe he hadn't thought of it before... Trying to get underneath Max just like a girl dog... It was probably the best thing in the world! The girl dogs must love it, especially since they liked standing around with the dick still in them once everything was done.

"It'll be tough, though. It's not easy taking doggy dick." Soh sat up and stretched his arms out, glancing at his son's glazed ass. "You're already a great slut, but this will be the ultimate test of your abilities.”

“The ultimate test!?” Tello cried. “I thought you said taking Sadanobu and Uncle Orn at the same time was the ultimate test?”

“That was when you were 7.” Soh said, chuckling a bit. "You're 10 now. It's time for another ultimate test."

"Ugh! Well, I'll show you, Dad." Tello flexed his arms heroically. "I can take any cock in the world! I'm unstoppable!"

They laughed together a bit, and Soh pulled his son into a tight hug, nuzzling his head. "Atta boy, Tello. How about we go to bed early, then? You should get as much rest as you can before we start."

"Aww..." He wanted to stay up a little longer to go see something one of his cousin's had found, a big weird-shaped dildo in their parents' room. But... If he was about to get fucked really hard, it would be best if he gave his butt a bit of a rest. "Okay. Can I, uh, still finger your dick a bit more? I wanna see if I can fit TWO in there."

"Of course, son."

-

"O-oh, jeez..." Tello gasped.

Max's face was buried in his crotch, licking and slurping on his tiny member just like any good dog was supposed to. He sniffed and nuzzled the boy's large sack as well, indulging in the scent of little boy crotch sweat. He may have been just a dog, but he was sensible enough to understand that he was in for some sort of treat. Besides, who doesn't like the taste of dick?

Soh stood behind his son, lightly rubbing his shoulders as the boy was thoroughly cleaned. "Doesn't that feel good? I bet it's much better than when I do it."

"Y-yeah..." Tello moaned. He didn't think he had ever been this hard in his life. Every time his cock started oozing pre, Max instantly swallowed it up and continued coating his balls in dog slobber. Tello had never experienced a tongue so warm and wet before; it was already starting to make him feel shaky.

They were behind the stables again like usual. Though the family avidly enjoyed sex and watching their young get fucked, Soh was usually more private and wanted Tello all to himself. He wanted to see his son take his first knot, hear him scream as his ass was brutally destroyed by Max's fat doggy dick. Hear him beg for help and receive nothing but a load of cum in his face in return. He pressed himself up against his son's back, biting his lip as Tello lightly humped Max's face. It seemed he might be getting close, and he didn't want Tello to get tired out already. 

"Alright, I think that's enough for now. After all, you should be the one cleaning his dick, hmm?"

"I-it feels so good though..."

"This'll feel even better." He turned him around so his ass was facing Max and reached down, spreading the boy's fat cheeks wide open. "There you go, boy. Here's something else for you to eat."

Tello cried out as the dog immediately shoved his face in his ass, eagerly cleaning the hole he was about to fuck. He loved having his ass tongued, and reached back to spread himself open as much as he could, giving Max full access to his well-used fuckhole. He couldn't wait to have it filled with doggy cum, have Max pound him mercilessly just like his dad every day. "This is... So good..."

"I'm glad you like it." Soh smiled. "Max sure does love little boy butt. Anytime you want your ass cleaned, I want you to go find Max, alright?"

"O-okay."

"The only tongues allowed on you from now on are myself and Max's. You got that?" He took Tello's chin. "Look at me when I'm talking to you."

"Yes, Dad!" The boy moaned. "I'll, uh... Uufff..."

"You're gonna become Max's fuck slave. You'll be his new girl dog, alright? How does that sound?"

It sounded wonderful. Tello certainly wouldn't mind being Max's toy if it meant he could get rimjobs like this. He eagerly nodded and went along with his father's lustful plan, sealing it with a hard, forceful kiss that made him choke a bit. His father's tongue always overpowered his own.

Soon, Max started to grow tired of eating ass and tried jumping up several times, wanting to mount Tello and get it over with. Soh laughed at this and led his son over to a soft spot on the ground, pushing him down on all fours. He checked Tello's hole; it was slick with dog slobber and clearly aching to be bred. That should be good enough. He called Max over and helped the dog up onto Tello. "Here, son. Take a look at what you're about to ride."

Tello squirmed and looked over his shoulder. His eyes widened as he saw Max's enormous 9 inch cock, very thick and very bright red. There was a bulge at the base of it that looked even thicker; was that thing really gonna fit inside him?

"See this?" Soh tapped the bulge. "This is Max's knot. When he's done fucking, he pushes this inside to make sure you get nice and full with his cum. You'll be guaranteed to get pregnant with his new pups."

"P-pregnant? I thought boys couldn't get pregnant..."

"Ah, silly little Tello." Soh grinned savagely. "You're not a boy. You're a girl dog, remember? You're Max's new bitch."

Before his son could respond, he hefted Max up and helped guide his cock into the boy's hole. Max started thrusting excitedly, jabbing Tello's butt painfully until he hit his mark, shoving himself deep inside the boy's ass. R-Regret! Tello screamed and struggled to stand up and push Max off of him. This fucking hurt! His ass was nowhere near ready for this. "D-Dad...! He's... He's really- A-AH!"

Soh sat down in front of Tello's face and pushed his head down onto his dick. "You belong to Max, now, and that means no whining. You're a big boy! I know you can take this."

Tello obediently started sucking his dad's cock, whimpering as Max thrusted into him wildly, the weight of the enormous dog pinning him down so he couldn't move. He'd been fucked dry before, but usually had a bit more preparation first before just going at it. He sucked it up though and held himself as steady as he could, spreading his legs wide to give Max better access to his ass. His hole was burning and no doubt bleeding a bit, but he liked the feeling of the dog's tool stabbing into him, spreading him wider with each thrust. His little boy ass could barely contain the whole thing, and he felt each and every jab against the underside of his stomach, feeling it bulge a bit from just how big it was. It hurt… A lot… But he was sure he could handle it.

His dad's dick wasn't anything too exciting; he'd sucked it clean hundreds of times, after all. It was always fun tonguing his foreskin though, sucking on the thick overhang and swirling pre around the head. He played with it for a bit before deepthroating it, feeling it leak pre deep inside his throat. It was comforting having something familiar in his mouth as his ass was brutally torn open by Max, and Tello did his best to make sure his father was pleased.

And Soh was indeed pleased. Seeing his son take to dog dick so well made him unbelievably hard, and he was glad he didn't have to force his son's head down at all; the little slut knew that he was supposed to swallow every last inch of daddy's meat. Max seemed to be enjoying himself as well, happily slobbering as he fucked tight little boy hole. "Good boy..." Soh cooed to the dog, rubbing his head affectionately. “I bet your poor balls are desperate to be emptied. Go ahead and go wild.”

Max's humping got more frenzied, his balls slapping against the bottom of Tello's ass. He was starting to get used to it a bit and enjoyed the burning sensation until Max suddenly thrusted harder than before, coating the boy's insides with cum. After several tries, he forced his knot in, causing Tello to shriek in surprise and choke on the dick in his mouth.

"Easy, easy..." Soh panted. He gave Tello a few comforting pats, keeping him locked down on his cock. "That's the knot, my boy! He came pretty quickly too. Your ass must’ve milked him just right."

Tello gurgled, holding back tears as his ass was on fire from the stretching and streams of hot dog jizz. This was a lot more painful than he had imagined it to be, and he wasn't quite sure if he really liked it after all. His dad was rough with him sometimes, but never anything like this! How could girl dogs stand getting fucked this hard?

"You're growing up so fast. Soon you'll be taking horses, just like your mother." Soh smiled and cupped Tello's straining cheeks. "We still have a long way to go, though. Hurry up and finish me off."

Tello obeyed and continued bobbing his head, running his tongue all over the length of his father's trembling cock. It was nice to have something to focus on while he was in such an intense amount of pain. It didn't take too long for Soh to grunt and thrust into his son's mouth, releasing torrents of seed for Tello to gulp down. After they finished, Soh helped pull Max off of Tello and turn him around so the two were ass to ass. Tello appreciated having the heavy dog off of him, but now he had to struggle to keep Max in one place as they were knotted. Soh watched with amusement as Max's every tug made Tello gasp in pain, the poor kid crawling backwards like an idiot as Max went to sniff several random areas behind the stable.

"D-Dad, can you help me a bit?" Tello grimaced. "This is fun and all, b-but he won't stay still."

"Sure." He bent down and picked up a rock. "Maxie!"

The dog stood at attention.

"Go fetch!"

The rock was thrown, and Max went barrelling off, instantly tearing his knot out of the tanuki cub's ass, sending cum flying everywhere. Tello screamed pitifully as his poor hole was violently emptied, torrents of cum and light amounts of blood dripping from his entrance. "F-fuck...!”

Soh burst into laughter.

“D-Dad! ...You're so m-mean!"

"Hey, you asked for help, so I helped." He squatted down as Max returned with the rock. "Get up and come here."

After much groaning, Tello managed to stand up and awkwardly limp over to his father. His entire body was shaking and his ass had never hurt this much before. He didn't even cum at all, yet he felt very drained. "Ugh..."

"How did you like your first dog fuck?"

"It was fun, I guess, but it hurts so much..." Tello winced as his father turned him around and spread his cheeks, examining his bruised hole. "I-I think I'm gonna stick with regular sex from now on."

Soh smiled. "A real man knows how to take any kind of cock without any complaints. Besides, the least you can do is clean up your mess first before making any hasty decisions."

"Huh?"

He gestured to Max's soaked dick, still waving around proudly. "You know the rules. Always clean up after yourself. You made Max's cock all dirty, so fix it."

Tello knew his dad was always strict when it came to rules like that, so he nodded and quickly got down on all fours again, crawling underneath Max's belly to try to suck him off. It was probably the muskiest cock he had ever tasted, reeking of cum and his own blood. The texture of dog cum was different too, a bit more watery and with a different sort of taste. Max stood there panting as Tello returned the favor from earlier, swallowing as much as he could. He didn’t mind the taste of blood too much. He’d licked it off his dad plenty of times after finishing a rough fuck session, and it always tasted way better when mixed with cum.

Soh licked his lips as he looked at this whole display. His son on the ground, happily slurping on the tool that had just ruined his ass. Tello had been raised well, that was for sure, but he still needed to learn how to not complain when he was given something. He lightly jacked off to his son’s fat dripping ass waving around, and then suddenly felt the urge to pee. He usually had to piss not too long after an orgasm. He stood up and let loose all over Tello’s back.

The boy jumped a bit in surprise. “Mmmph?”

“It’s fine. Just had to pee.”

Tello grunted and continued with his task, but was surprised once again as Max started walking away from him, heading around to sniff the boy’s piss-soaked hole. “H-Hey!”

“Hmm.” Soh backed away a bit. “It seems he still wants to have a bit more fun with you.”

"N-no! Down boy, down!"

He tried in vain to get away, but Max mounted him just as he tried to stand up, slamming him back down onto the ground. He struggled to throw Max off, but was once again subdued by the animal's weight and in too much pain to move around much. He gasped as he felt his father's hand guide Max back in, and soon he was on to round two, his new owner happily tearing open his hole once again. "A-ah! M-Max, get down...! Please... Agh!"

Soh chuckled and looked around for Max's leash. He had left it somewhere nearby... Ah, right here. He calmly ignored his son's cries and protesting as he undid Max's collar and put it on Tello, securing it a bit too tightly. He put the leash on and tied the other end to board jutting awkwardly out of the back of the stable in front of them. "There we go. I'm gonna go get some lunch for us. You can stay here and keep having fun with Max."

"DAD!" Tello yelled. "Th-this isn't funny! This really h-hurts... Please, I... A-aaah...!"

The older tanuki shook his head. "I told you this was your ultimate test. Besides, you know full well you like it. You were so excited yesterday, and now you're sitting here complaining? Toughen up."

Tello panted and clenched his teeth. His dad was right. He wanted to be a big boy, so he had to learn how to take big boy dick. His entire body shook with the force of Max's thrusts, and he did his best to keep himself from crying out. He wished he could at least have a break before going at it again!

"You see, to Max, you're just something to fuck. Your purpose is to take all of his cum and make a fine litter of puppies for him. That's why it's so rough. People like Sadanobu care about you and what happens to your ass. Max just cares about cumming. You'll get used to it in no time, I promise."

"O-okay..." Tello whimpered. "I'll try..."

"Good boy. I'll be back in a bit, alright? Just relax and focus on being a good bitch.”

...Would do, Dad. "C-can you get me something to- Aaah! ...D-drink?"

"Of course!"

-

"He knotted me three more times after that." Tello said, reaching over for another piece of sushi. "And my dad didn't really get me anything to drink. He just pissed in my face."

"Wow..." Char said. "Your dad sounds weird."

"Eh. Who wouldn't want to see their kid get dogfucked? I should introduce you sometime. He'd love you."

Char squirmed. "R-Really? That would be cool, I guess... Only if he's as nice as you, though."

"He's passable. Let me warn you, though. My ass was raw for two or so weeks. It was awful just trying to sit down. And my dad's super impatient, so that wasn't fun either..."

As Tello continued on, Char thought about Tello and his dad both cuddling him and playing with him. If Tello could make him feel good, imagine how great two Tellos would be! And playing with a dog didn’t sound half bad either. It had hurt when Tello first fucked him in the park, and a few of times after that as well, but he was pretty used to it now. How much worse could a dog be?

"-and he's into way younger ones too, like, at least let their asses finish growing somewhat before you just destroy them."

"It would be cool to meet your dad." Char yawned. "And maybe it would be fun meeting Max, too."

Tello laughed. "Sure, sure. Let's get you into bed, though. We won't be able to break our record tomorrow if you're all tired out."

He cleaned up and led the tired boy into the bedroom, and set a reminder on his phone to give his dad a call later. It had been a while since he'd seen the old man, and they were due for a little meet-up. After all, nothing helps you bond with family better than reminiscing about old times and sharing a cute little fuck toy.

He couldn’t wait to hear Char scream again.
