Teddy squealed in delight, his fat bear-cub face wobbling, as his Papa brought his new pup in to greet him. The dog was built like a brick shed, all bulging muscle and high-sheen fur. A pit bull. It would have been intimidating to a grown man, but Teddy was eleven years old; he had always wanted a dog, and now this one was his. A friend of his very own. Teddy had no other friends, because Teddy couldn't leave the house. Literally. He was nearly six hundred pounds of burgeoning, obese bear-boy. When sat on the couch, his huge buttocks took up nearly a cushion each. His legs were splayed sideways by his enormous, burgeoning belly - the bottom of his gut got tickled by the carpet, that was how close it was to touching. He was so enormously fat he started wheezing before he even fully stood up. He hadn't been to school in over a year, and ever since his weight had ballooned. His homeschool work sat piled at the end of the couch - Papa didn't care if he did it or not. Teddy prefered to stuff his face and watch cartoons, and Papa didn't mind one bit. So Teddy had gotten fatter and fatter, and now he was a very fat boy - much fatter than he ever could have imagined becoming. But none of that mattered, because his new pup had jumped up onto his tummy, its front paws batting at his swollen, bloated boy-boobs, and had started licking insistently at his many-chinned face. He adored it. Loved it already, even. "Thanks, Papa! Thanks so much!" He was ecstatic, laughing. Enjoying the moment. Happier than he'd ever been. "Get ready for dinner, boy." His Papa said, smiling endearingly at his son. "Gonna pick up your special favorite." "Oh! Oooh! Fried chicken, or bacon burgers?!" His Papa chuckled. "You're getting both, son." Papa left to pick up dinner, and Teddy was so pleased. So was his new pup. His new pup seemed very pleased, indeed. "I'll call you Daisy!" Daisy kept getting more and more excited. The pup was positively trembling with anticipation. Its puppy kisses became even more insistent, assertive. Unrelenting, even. Less than a minute after Papa had left, Daisy's tongue had wormed its way inside Teddy's mouth and was lapping at his gums, his teeth, his own tongue. Teddy was having trouble catching his breath. He was getting dizzy, light-headed. He pulled back as far as he coul, but his huge butt and back rolls smooshed into the couch cushions and blocked him. "D-Daisy!" he sputtered, but the pup shoved its tongue right back into the little (enormous, rotund, morbidly obese) bear cub's mouth. The minutes dragged on. Teddy's heart was racing, pounding, hammering in his chest. He could barely draw breath through his nose, but tried as hard as he could. Daisy simply refused to stop its slobbering, tongue-heavy kissing. It was weird. Teddy even felt weird himself. He rocked his great weight forward instead of back, and managed to get his plump, fat-encumbered feets onto the floor. Teddy still felt weird - he wanted to keep kissing his pup, because it was kinda cute. But it felt funny, and he wanted to do it in his room so he could stop right away when Papa got home. As soon as he stood, Daisy immediately circled around him. The pup's nose sniffed and nuzzled and nipped at Teddy's backside, its tongue lapped lazily at his little tail peeking out atop his globular buttocks. "Hee hee... Hello to you too, Daisy!" He giggled. Daisy followed him all the way to his room, and nuzzled at his backside all the while. --- "What do you mean, a mix-up?" Papa had received a phone call as he pulled out of the burger place parking lot. The voice on the other end of the line was panicked. "What do you mean, a breeding stud? Why does that matter?" The trainer explained quickly, with much innuendo and euphamism. "What do you mean, customers with eccentric taste?" More fast talking from the breeder. "D-don't leave my boy alone with it?" Papa's blood ran cold. "Or what?" But he knew what would happen - he had left his precious little fat boy alone with a fuck-starved hound trained specifically to breed booty. --- Teddy tried not to panic. When he'd tried to crawl into bed on his hands and knees, Daisy had jumped right up with him - and then the pup had caught the hem of his huge undies in its teeth and had started to pull them down. "H-hey, wait!" he stammered, a measure of panic creeping into his voice. "I don't wanna be nakey right now, Daisy!" But his undies were now down past the bottom of his wobbling, beachball booty. And now Daisy had scrambled up onto his big rump, hooked its front paws into the crevices between his hips and belly, and had started to wrestle with his butt. Teddy's entire, fat body was shaking and shuddering from the assault - he could even hear Daisy's hips clapping against his buttocks. And then his eyes went wide as tea saucers - Daisy had given one particularly strong buck, a most determined, powerful thrust, and something huge and steaming hot jabbed into Teddy beneath his tail. Daisy had just buried his enormous, canine bone in the bear cub's back porch, and went right to work drumming a speedy, relentless beat against his wobbling ass. Teddy's drawn out, high-pitched shriek sounded just like a pig's squeal. --- Papa burst through the front door and immediately heard the sounds of a brutal fucking coming from his son's room - the raucous clap of fat asscheeks, the heaving, shuddering breath of the breeding stud, and the moaning, urgent pleas from his boy for Daisy to stop. He pulled the dog away, managed to get it out of the room, and shut the door. His boy was still panting, wide-eyed. Moaning. His bare, fat rump was still on display, reddened a bit from Daisy's assault. "P-paaaaaawpa!" Papa's eyes were as round as his son's. He was breathing heavily. He took in the sight of his fatfuck boy, still on his hands and knees, his rotund belly spilling out to either side on the mattress. An ideal position for what had just happened to him. A most ideal position. Papa's sweatpants were tented, and prodigiously so. He was a fit man, with toned and somewhat bulging muscles. His own Papa had been a stallion, and he'd inherited certain of his father's assets. His cock was thirty-two inches long fully erect, and at the moment it felt as though it were harder than it had ever been; its girth, an easy five inches at its widest, felt achingly stretched, as though more blood than ever before had been forced into it. An earnest heat exploded in his belly, an extreme lust more profound than any he had ever experienced. He grasped his cock with both hands, and cried out from the near-pain he caused that horrendously sensitive flesh. The fingertips of both his hands barely brushed together around the circumference its girth. It was burning hot, baking between his palms. He was fully flared, and that swollen hood felt ready to burst. He'd never needed a fuck so badly. And what he so desperately needed to fuck was this grotesquely obese, fatfuck bear cub - his own son, freshly reamed and conveniently prepped for enormous bearstud dick. --- "D-Daisy started k-kissing me, Papa! On the mouth! And it felt real funny, so I got up and-" Papa put a hand under his chin, used his forefinger and thumb to cup his fat face, and leaned in close. "Kissed you?" Papa's voice was low and husky, and he was so close Teddy could feel hot breath on his face. "Like this, Teddy?" And then Papa's lips were pressing hard against his, and Papa's tongue filled his mouth up. Teddy moaned as Papa's tongue did exactly what Daisy's had done, but rougher, harder. He moved his own tongue, and Papa's wrapped around it, tugged at it. Then it was in Papa's mouth, and he was feeling papa's tongue and teeth. They separated, and saliva clung between their lips as they panted. They spent several seconds looking deep into each other's eyes. Then they were at it again, Papa's tongue shoved deep into his mouth. Teddy moaned and moaned as his daddy felt him up, shook his burgeoning love handles, wobbled his big fat belly, squeezed his enormous boy-tits, their sensitive nipples wide as pancakes. He groaned and gasped and clung to his daddy as he felt those big, strong bear arms embrace him, felt safe and secure and... funny. Funny like when he'd been kissing Daisy, but stronger than ever. Their lips parted once more. "P-pawpa?" Papa grunted a deep, rolling growl. Affectionate. Dominant. Hearing that low, guttural thunder, Teddy knew he was his Papa's special boy. "A-are you gonna wrestle my b-butt too?" He stared into his daddy's eyes, and Papa stared into his. There was so much more in that gaze now, so much heat, so much mysterious, unknowable feeling. Teddy started licking his daddy's lips, eager for more kissing. This felt right. This felt like what he should do now. Daddy grinned a lopsided, sideways smile. It was a predator's grin. It looked very handsome on his daddy's face. "Yes, boy." Teddy's tongue lapped into his daddy's mouth when it opened, and Papa was very careful with his teeth. They kissed, but briefly. Teddy moaned when it was finished, needing more, addicted. "Papa's gonna fuck ya' good, Teddy." He kissed his son again, and after several seconds he nipped Teddy's fat lower lip. Teddy yelped. He hand't bit hard enough to hurt the boy, just sleight pressure with his teeth. But they were so worked up, so sensitive. So ready. He loomed behind his son like a muscled monolith, his cock spearing out toward fat bearcub ass. His flaring cockhead seemed much too large, but they both knew it would fit. Father and son panted for breath, the anticipation palpable, and they both gasped and moaned as he sloooowly entered his boy. He paused halfway in, drinking in the noises his obese pig of a son made, the whimpering and gasping and moaning fuck-music. Then he rammed his meatlog home, and they both howled together as one claimed the other. Their pace was breakneck, fast as lightning; the bedframe creaked and groaned and slammed repeatedly into the wall as Papa battered his son's fat ass. He came so hard, his climax so all-consuming, that he almost blacked out. But he remained on his feet, clutching his obese boy close as he fired firehose ropes of steaming spunk deep into his son. They made out after, between bites as Papa hand-fed his boy ridiculous amounts of greasy, fattening fast-food. They put a movie on, and missed half of it kissing, slurping their tongues together and exploring one another's mouths. They missed the other half because Teddy had begged his Pawpa to fuck him again, and Papa complied immediately. They did it lying down this time, Teddy on his side, so fat his belly still drooped over the side of the mattress. Papa bred him nice and gentle this time, slowly pistoning his three foot dick in and out of his disturbingly obese cub's fat, wobbling, vice-tight ass. They moaned and whispered to each other as they fucked. Teddy told his daddy that he loved him very very much and to please not stop. Papa called Teddy his eager little fat bitch, and after he'd explained what that meant, Teddy told his Papa that he wanted to be his fat bitch forever and ever. Papa called it a deal, and they sealed it with a loud, sloppy kiss.
