Gwen could not believe her own eyes as the large puppy was hauled onto the lawn by a crane. Zephyr was a golden retriever puppy who had recently been kidnapped and fattened to immobility by a strange scientist. Then Toma, Gwen's current owner, had bought Zephyr for Gwen to play with at their mansion. Zephyr's belly lifted his feet a few inches off the ground, and his ass hid his tail. His butt also his his hind feet in sagging golden flab. The scientist who turned Zephyr into this fat blob had also given the golden puppy a serum that enlarged his cock and balls. But after a few hours of his last injection, Zephyr's bits were shrinking back to normal size. The serum had also made Zephyr's mind fuzzy, and now he was finding himself able to speak again. "Oof. I'm glad to be away from that crazy scientist." Zephyr said looking around at the yard he was just dropped in. It was a spacious yard with a big modern mansion at the edge of Zephyr's limited peripheral vision. He gave himself a shake, by which, he jiggled vigorously sending some sweat into the air. Gwen giggled, she placed her front paws on the belly flab in front of Zephyr and gave his face a friendly lick. "So you can talk now?" "Uh huh." Zephyr nodded. "I've missed being able to communicate with folks." Zephyr sighed, but then quickly shook it off. "But I'm glad to be out of there," Zephyr continued, "Still... I can't move. And I'm really hungry." Gwen laughed, "Well, when I bought you, the very first thing I was going to do is feed you!" Zephyr's ears perked up happily. "Oh, well, I'm starving!" "Of course, I'm gonna get one of the servants to bring you lots of food!" Gwen hopped up and kissed Zephyr on the nose before bounding off towards the mansion. Zephyr laid there waiting and sweating in the sun once more. He was getting used to constantly sweating by now, the golden puppy's perpetually damp fur didn't bother him anymore. And the musk that filled the air around him was comforting in a way. As a dog's nose didn't adjust to smells, Zephyr was always aware of just how bad he stunk. Gwen soon returned with a servant. The servant was pushing a food cart covered in various treats which Zephyr could smell from a ways off. Zephyr smelled that each plate held a different type of junk food, including cakes, cookies, milkshake, and potato chips. His stomach growled noisily and he began drooling in anticipation. This food is far better than the leftovers he used to be fed. "You're getting the good stuff today!" Gwen sat down in front of Zephyr. "This'll fatten you up wonderfully." Gwen looked at Zephyr affectionately. Gwen leaned against the blobby pup, smiling seductively at Zephyr. "Are you ready for your first meal as my boyfriend?" B-boyf'wiend? Zephyr blushed. Sure she was cute, and attractive, but they had only just met earlier that day. "Well...?" Gwen was holding back the servant until she got an answer. "Well... I'm your boyf'wiend?" Zephyr said. Gwen nodded slowly. "Um, I don't have a p'woblem with that!" Zephyr smiled and purred. This could be fun, being Gwen's boy. Gwen motioned for the servant to begin feeding Zephyr, her tail wagging. "There we go! All yours then, my new boyfriend. Eat up, Zephyr. We gotta get you nice and plump." The servant started with the potato chips followed by the cookies and cake. Every few bites Gwen had her servant stick a funnel into Zephyr's muzzle and pour in a thick milkshake to wash it all down with. Gwen was staring in awe to see how much more food Zephyr could fit in his stomach than a normal puppy like her could eat. She thought for sure that her boyfriend would be full with each new cookie or each bite of cake, but Zephyr kept at it diligently. After one hour of eating, the golden puppy was as bloated as ever, he couldn't help but let loose a belch after finishing the milkshake. Eventually, the servant came to a halt, exhausted. As he wheeled the cart away, Gwen pushed herself to her feet. "How did you like that feast?" Gwen said. "I loved it!" Zephyr said through his purring. "Is there any more?" Gwen didn't expect that response, her puppy was still hungry? She was thrilled. There's nothing else quite like having a fat lover lie beside her and keep her warm at night. She could hardly wait to sleep with Zephyr later. "Wait a moment, and I'll get the cooks to make you even more food." She ran off leaving Zephyr to savour his meal and the sound of Gwen's voice. Zephyr found her obvious excitement to be contagious. He was steadily falling for the spaniel pup, and felt less anxious about being here with Gwen. The golden retriever was filled with curiosity, wondering what lay ahead for him. Gwen returned an hour later with a new servant and a new course of tasty treats. Gwen said that the milkshakes were gainer shakes. "I want to see you put on more weight," Gwen teased as she fed Zephyr more junk food. Zephyr blushed but nodded, his tongue lolling out of his mouth as he swallowed the last cookie. His stomach was finally getting full and he was in a state of bliss. Eating seemed to be so much more fun now that Gwen was here telling Zephyr how big she wanted him to get. Zephyr burped again after finishing the meal. "You don't seem to mind how bad I smell, do ya?" Zephyr asked. The golden retriever was beginning to accept his own stench and was starting to feel comfortable around Gwen. Even if the scent of his musk hung heavily in the air around them both. He had noticed that he was becoming more and more attracted to Gwen as well and didn't want to gross her out. "No, I'm not bothered at all." Gwen rubbed her little body against Zephyr's sweat soaked fur and gave his fat cheek a quick kiss. "Why should I be?" She smiled sweetly, and winked at Zephyr. That night, Gwen jumped up onto Zephyr's back and curled up for bed in Zephyr's flab. They slept together that night, cuddling. *** Every morning started off with Toma coming out and feeding Gwen her kibble and a servant fed Zephyr last night's leftovers. Zephyr became curious about what kinda food he would be fed for breakfast, and eating leftovers eventually became a highlight of his day. During the day, a servant would come out a few times to feed Zephyr treats while Gwen caressed Zephyr. At dinnertime, Toma would have his rich neighbors come over to ogle at the 'repulsive mutt'. Zephyr tried to ignore their hurtful comments because they would bring their leftovers for him to eat and dispose of. The folks who brought their scraps to Zephyr were wealthy merchants and aristocrats, so Zephyr often enjoyed lavish meals. Zephyr steadily grew fatter and fatter. Zephyr's face was plump with two huge cheeks. His fat chins blended into a couple neck rolls. His belly had pooled around him and lifted him up to the eye level of the adults. Zephyr's forelegs were thicker than any of the adults' whole bodies, his paws were fat and he couldn't even wiggle his digits. He had several layers of lard packed onto his back, and his ass rose into the air above him before sagging down over his hind legs and towards the ground. Eventually the big golden retriever puppy could barely remember the days he was an active pup, all his time and attention were focused on eating new foods and making Gwen happy. The two puppies would spend hours talking about the stuff Gwen was up to. More often than not, Gwen would share gossip and stories of the other dogs in the area. Of course, they also talked about Zephyr's growth and Gwen's plans for him. Zephyr was enjoying himself tremendously. As he kept growing throughout the following months, the fat on Zephyr's back rose above his head forming new folds there. And his forelegs were soon to be hidden in between his neck and belly rolls. By this point his belly made him taller than anyone else, and the servants were starting to strain to reach Zephyr's drooling muzzle. On top of this, Zephyr was experiencing a surge in his appetite. He couldn't even focus on his conversations with his girlfriend unless he was eating; the hunger pangs causing Zephyr to moan and whine. One evening, as Zephyr watched Gwen play with her friends in the garden below him, his stomach gave out a huge growl demanding food, a sound that was distorted through all the blubber. Gwen turned to her startled friends who had no idea what the sound was. "Don't worry guys, Zephyr's just hungry again." Zephyr whimpered and nodded. "Hey Zephyr, if you're hungry you should eat up." Gwen glanced up at her boyfriend who was panting and drooling slightly. Gwen was quick about fetching a servant. Her puppy friends stood around the bloated pup, none of them had ever spoken to Zephyr before. None of them had ever gotten close to Zephyr due to his stench. Without Gwen, they felt awkward. One of the girls nervously approached Zephyr and stroked his flabby chest. Zephyr's gut pulsed beneath her paw, sending waves of pleasure through his body. His tummy rumbled again, louder and more insistently. "G-good boy!" the girl pup said before backing off completely and rubbing the grass to get the sweat off her paw. Next another girl approached, who decided to take an unfortunate sniff. "Oh my dog, you are so smelly!" "I bet he smells like bacon!" The third girl, a bit bolder, took a bigger sniff. "Oh nope, wow that's strong. You seriously need a bath." Zephyr was kind of enjoying the attention, even though he failed to make a good impression on the three girls. Zephyr was actually bathed just yesterday. Toma had a team of servants hose him down, and Gwen helped to scrub the old sweat off. That had taken them all day long. The servants came out with Zephyr's third lunch, and Gwen was back to playing with her friends. His stomach was grumbling loudly and the vibrations caused Zephyr's fat belly to jiggle. *** A year passed and Zephyr continued to grow, gaining more and more weight. Zephyr was absolutely massive now. His face had become harder to see as he was buried in flab, and both his belly and butt were taking up more and more space on the lawn. Toma had to install a food pump to deliver Zephyr his meals as the servants could no longer reach Zephyr's head. So he was once again eating slop from a hose, but at least now he was enjoying it. Gwen would often climb up Zephyr's belly and snuggle in the growing folds beside his cheeks. She would give him kisses and rub her little paws along his furry chin. Gwen was ecstatic to see how fat Zephyr had grown, and she loved seeing him eat more. She would always bring up treats and snacks for Zephyr, which he happily gobbled up. One day, Toma's neighbours came by to gawk at the giant puppy and mock him for being such a pig. Gwen defended her boyfriend from those cruel words and Zephyr was grateful. Zephyr's whole life revolved around Gwen and getting fatter for her. He couldn't stop thinking about her and only her. She filled his dreams at night where he would imagine running and playing with her. He wasn't disappointed when he would wake up to his immobile body as he would always find himself wanting to please Gwen, and spend the next day getting even fatter. And Gwen's life revolved around Zephyr and watching his body slowly overtake the lawn, his belly approaching the mansion. She would watch as the servants struggled to wash him, and they would often fail to wash all the grime and sweat off the fat puppy. She would rub her paws all over his belly and tease him for being so smelly. Zephyr grew to the point his back flab covered his head, merging with his neck and belly to form a sorta tunnel of golden fat leading to his face. Toma had braces installed to hold up the expanding fat tunnel, and fairy lights along the path. The pup felt so hot and heavy, in more ways than one. He felt like he was melting away into a blob of fat. Every part of his body was saturated with lard and sweat, and his fingers were stiffening up. Zephyr was completely immobile, and he couldn't even wiggle his toes or tail anymore. He didn't think he could possibly get any fatter, but he found that was wrong. Gwen was very proud of how fat her boyfriend had become. Zephyr felt Gwen climbing up his mountainous belly, and trek through the tunnel before she finally reached Zephyr's face, a feeding hose still pumping food into him. The tunnel was dripping with so much sweat that Gwen was half-soaked by the time Zephyr saw her. "Good boy," Gwen cooed at Zephyr. "You did so well today." She rubbed her paws all over Zephyr's face, feeling his soft fur. Her paws felt strangely warm and smooth against his fat skin. She leaned in and kissed Zephyr. It was a nice kiss, one that would melt the heart of any lucky pup. "I think you deserve a treat, big boy." Gwen made her way back out of the tunnel and climbed up onto her boyfriend's back. She lay down and began to caress Zephyr's flabby shoulders. Zephyr moaned and twitched, Gwen was happy to continue her massage. Gwen gradually made her way down the giant puppy's backside and onto his massive ass cheeks. She started to rub them, knowing how much Zephyr loved it. Her loving touch was like a drug to Zephyr, and he wanted more. She let out a low moan. Gwen loved how heavy and squishy Zephyr's fat ass felt under her paws. She slipped down into the crevice of Zephyr's sweaty ass and felt her way to his balls. Gwen placed her paws on Zephyr's sack and squeezed and massaged the fat orbs. Her warm breath wafted over Zephyr's sensitive sack, causing his belly to quiver and vibrate. Zephyr let out a deep groan, and Gwen smiled. She leaned in to take his thick dick into her mouth. The fat cock was almost too big for her small muzzle. But she managed to fit it in and began sucking on Zephyr's fat shaft. Zephyr's belly was pulsing as he began to purr, and Gwen knew it was turning him on. Gwen pulled her muzzle off of Zephyr's dick and licked up his leaking pre-cum. She grinned, knowing she'd turn him on further. She leaned in and sucked Zephyr's bulbous head until she received a loud moan from her boyfriend. She began to suck harder, and Zephyr grunted and gasped as Gwen worked his fat meat. She slowly bobbed her head up and down on Zephyr's fat shaft, giving him a slow blowjob. Zephyr couldn't do much, so he started sucking hard on the food pump. The pump was programmed to pump slower if Zephyr fell asleep and faster when he showed signs of needing more. So now Zephyr's belly was filling up with more and more slop as Gwen took her time. Gwen's tongue swirled over the tip of Zephyr's cock, and she could tell he was close. She licked his shaft and sucked more of his fat cock into her mouth. Gwen was taking her time, making sure Zephyr got everything he needed. And with every lick and suck, Zephyr's belly began to swell and growl louder and louder. With each pump of the food pump, Zephyr grew closer to cumming. Gwen could feel his dick twitch inside her mouth, and she knew he would cum soon. Zephyr's fat belly filled up with more and more food, and his cock exploded with cum. Gwen's mouth flooded with goo and she quickly swallowed it all down, not wanting to waste a drop. Gwen soon climbed back down Zephyr's backside, cleaning herself and making her way back to his face. She sighed happily, satisfied that she had pleased her boyfriend. Zephyr was panting heavily. Gwen looked at her boyfriend and smiled. He looked so cute, and he had just made her happy. She leaned in and kissed him. "That was amazing," Gwen whispered to Zephyr. "Did you enjoy yourself?" She pulled the hose out of Zephyr's muzzle, which had run dry. "Yeah, that was amazing..."
