Chapter 15: Cum-Fattened Fox
The ghost of Cream was a tangible thing. It lived in the indent on the left side of the couch, a perfect little nest where she’d curl up with her storybook. It lived in the single, small controller on the charging dock, always full, never used. But mostly, it lived in the smell that had begun to permeate the house, seeping under the door of the gaming den and into the very walls: garlic butter, rich and savory, and the yeasty promise of rising dough.
Vanilla’s absence was a different kind of presence. She’d taken Cream to her sister’s for a “long weekend” that had stretched into a week. The care packages arrived daily. Not cookies. Massive Pyrex dishes of baked ziti, layers of cheese and sausage bubbling under a crust of golden breadcrumbs. Loaves of garlic bread wrapped in foil, still warm, soaked through with butter. The fridge groaned with them.
Knuckles didn’t bother with plates anymore.
Tails knelt on the floor, the shag carpet scratching his knees. Before him, on the low coffee table, sat a casserole dish the size of a tombstone. Knuckles was sprawled on the couch, his back against the armrest, his feet—swollen, socked—planted on the other. The vast plain of his stomach rose like a tan, furred moon, eclipsing the view of his own face. He held the dish on his lap, its edges digging into the soft overhang of his belly.
“Open,” Knuckles grunted, his voice muffled by a full mouth.
A glob of red sauce and creamy ricotta dripped from his chin onto the fur of his chest. Tails obeyed, leaning forward. He didn’t need to be told what to do. He extended his tongue, cleaning the mess with slow, deliberate laps. The sauce was garlicky, rich. The cheese was tangy. Underneath, the salt of Knuckles’s sweat. Tails moaned softly, his hands resting on his own stomach. It was no longer flat. A soft, definite paunch pushed against the waistband of his shorts, a mirrored, miniature version of the mountain he serviced.
“Good boy,” Knuckles rumbled. He scooped another massive forkful, but instead of eating it, he held it out. “Now you.”
Tails leaned in further, taking the fork into his mouth. The flavors exploded—sausage, basil, tangy tomato. It was delicious.It was punishment. He chewed and swallowed, feeling the heavy satisfaction of it settle in his own gut.This was their ritual now. Knuckles would eat, and Tails would clean him. Then Knuckles would feed Tails, watching with dark, intense eyes as the fox’s slender frame disappeared bite by bite. Tails’s love handles, once a teasing fantasy, were now solid realities he could grab onto. His thighs rubbed together when he walked. His reflection in the dark TV screen was a stranger—softer, rounder, owned.
Knuckles set the empty dish on the floor with a thud. His hand, slick with grease, slid down his own belly, past the waistband of his straining sweatpants. He sighed, a contented, guttural sound. “Fuck, I’m stuffed. Like a goddamn tick.”
He was. His belly was a taut, impressive drum. The earlier softness had been packed solid, a dense mass of pasta and meat. He breathed shallowly, each inhalation a conscious effort.
“Come here,” Knuckles said, his voice dropping to a low command.
Tails crawled forward, between Knuckles’s spread legs. The smell here was overpowering—garlic, sweat, the musky, animal scent of Knuckles’s crotch. Knuckles didn’t move to open his pants. He simply looked down, his eyes heavy-lidded.
“You know what to do.”
Tails’s fingers trembled as he worked the drawstring. The knot was tight, strained by the pressure beneath. He finally loosened it and pulled the waistband down. Knuckles’s cock, thick and half-hard, lay against the shaved, swollen curve of his lower belly. Beneath it, his balls were a heavy, full sac.
But Tails didn’t go for his cock. He’d learned. He bent lower, his nose nuzzling into the hot, dense fur at the base. He inhaled deeply, the primal scent making his head swim. He licked a long, slow stripe from Knuckles’s taint up to the base of his shaft.
Knuckles jolted, a full-body shudder that made the couch springs scream. “Fucking… yeah. Just like that. You’re a nasty little thing, aren’t you? Licking the sweat off a fat fuck.”
Tails didn’t answer. He worshiped. He licked and nuzzled, his hands coming up to knead the enormous, food-filled belly that loomed over him. He could feel the contents shift, a sloshing, solid weight. He was hard, painfully so, his own cock straining against his shorts, trapped under the new softness of his own gut.
“Get up here,” Knuckles growled.
Tails climbed onto the couch, straddling Knuckles’s massive thighs. He was facing him, looking down into Knuckles’s flushed, satisfied face. Knuckles’s hands came up, not to touch Tails, but to grasp his own love handles, squeezing the dense fat there.
“Look at you,” Knuckles sneered. “Getting a little soft belly on you. You like eating my leftovers, don’t you? My little garbage disposal.”
Tails nodded, unable to speak. He rocked his hips, his clothed cock rubbing against the hot, firm dome of Knuckles’s stomach.
“You wanna fuck this?” Knuckles asked, slapping his own gut. It didn’t jiggle; it was too full. It made a solid, drum-like thump. “This big, stuffed gut?”
“Yes,” Tails whined.
“Then get it out.”
Fumbling, Tails pulled his own cock free. It was slick with pre-cum. He leaned forward, bracing his hands on the back of the couch behind Knuckles’s head. He positioned himself, the head of his cock pressing against the slick, sweaty fur of Knuckles’s lower belly, just above his navel.
“Go on,” Knuckles taunted. “Fuck it. Pretend it’s my ass. Pretend you can even reach it anymore.”
Tails pushed forward. His cock slid along the furred slope, a shallow, frustrating friction. He was fucking the curve of Knuckles’s stomach, humping against the solid, food-packed mass. It was degrading. It was incredibly hot. Knuckles laughed, a low, mean sound, and gripped Tails’s newly soft hips, guiding him, grinding him harder against the unyielding bulk.
“That’s it,” Knuckles panted. “Work for it, you little bitch. Jesus, look at you. Panting like a dog. Your cute little fox belly jiggling.”
Tails could feel it, the bounce of his own new weight with each thrust. The heat from Knuckles’s body was immense, enveloping. The sounds were wet, slapping, animalistic.
“I can feel it,” Knuckles groaned, his eyes closing. “I’m so fucking full. I can feel every pound of that ziti in there. And you’re just rubbing your little dick on it like it’s the best thing you’ve ever had.”
“It is,” Tails gasped, his rhythm becoming erratic. “It is, Knuckles, please…”
“Please what? You gonna cum all over my fat stomach? Mark your territory?”
“Yes! God, yes!”
Knuckles’s hands moved from Tails’s hips to his ass, gripping the soft flesh there, pulling him harder, faster.“Do it. Make a mess. Show me what my good little feeder does when he’s full of my food.”
The permission, the filthy words, the overwhelming sensory overload—it was too much. Tails cried out, a sharp, broken sound, and came. Thick stripes of white shot across Knuckles’s red fur, painting his stomach. Tails collapsed forward, his face pressed into Knuckles’s neck, his body trembling through the aftershocks.
Knuckles let him lie there for a moment, spent. Then his hands pushed Tails off, back onto the floor. Tails landed on his ass, looking up, dazed.
Knuckles looked down at the mess on his belly. He snorted, then used two fingers to scoop up a glob of Tails’s cum mixed with his own sweat. He held it out.
“Clean it up.”
Tails, still shuddering, leaned forward and took Knuckles’s fingers into his mouth, sucking them clean. The taste was bitter, salty, utterly his own.
“Now,” Knuckles said, heaving himself sideways on the couch with a groan that spoke of profound fullness. He reached down to the floor and picked up the casserole dish. With a thick finger, he scraped along the inside, gathering the last clinging bits of cheese and sauce and browned bits. He held the finger up, glistening.
“There’s still some left. You didn’t let me finish.” He shoved the finger into Tails’s mouth. “Suck it clean. Then go get the garlic bread from the fridge. The whole loaf.”
Tails sucked obediently, his eyes wide. Knuckles settled back, his hands resting on the monumental swell of his stomach, a king on a greasy, crumb-strewn throne. His eyes were already drifting shut, a small, cruel smile playing on his lips.
“And Tails?” he murmured, not opening his eyes.
“Yeah?”
“Bring the butter too. The whole tub.”
Tails moved through the kitchen on autopilot, his limbs heavy. The cold light of the refrigerator bathed him in a sterile glow, a stark contrast to the den’s humid darkness. He pulled out the foil-wrapped loaf, its weight substantial, and the plastic tub of butter, chill and solid. He carried them back like an offering.
Knuckles hadn’t moved. His eyes tracked Tails as he approached, a lazy predator observing its prey return. “Peel it,” he commanded, his voice thick from near-sleep.
Tails’s fingers fumbled with the foil. The garlic smell, once comforting, now felt cloying and aggressive. He broke off a steaming segment, the heat nearly burning his pads, and dipped it into the soft yellow butter until it dripped.
“Feed me,” Knuckles said, closing his eyes. He opened his mouth.
It was a mechanical ritual. Tails pushed the sodden bread between Knuckles’s lips. Knuckles chewed slowly, swallowing with audible effort. The immense belly on his lap seemed to tighten, growing more rigid and full with each bite. Tails fed him another piece, then another, watching the adam’s apple in Knuckles’s thick neck bob with each forced passage.
“Your turn,” Knuckles mumbled around a mouthful, gesturing with his chin. Tails took a bite of the next piece. The butter was slick and overly salty on his tongue. He ate it because he was told to, the act devoid of pleasure, only submission. They passed the loaf back and forth until it was gone, a shared, silent bloating. Knuckles’s breath became a wet wheeze. A sheen of new sweat coated his fur.
“Fuck,” he exhaled, the word strained. His hands roamed over the drum-tight curve of his stomach, pressing experimentally. A low, guttural sound of pained satisfaction rumbled in his chest. “Pants. Get them off me.”
The drawstring was buried under the shelf of his gut. Tails had to tug hard, his face pressed into the hot, furred flesh. The smell of him—garlic, salt, deep musk—was dizzying. The sweatpants gave way, sliding down his tree-trunk thighs. Knuckles’s cock, thick and inert, lay against the incredible swell. Tails knelt there, awaiting instruction.
But Knuckles just breathed, his eyes closed, one hand idly stroking his own stomach, the other buried in Tails’s hair, not guiding, just possessing. The silence stretched, filled only by Knuckles’s labored breaths and the hum of the game console on standby. Finally, his hand in Tails’s hair tightened. “Go on,” he whispered, barely audible. “You know you want to.”
Tails didn’t need a clearer invitation. He bent, taking Knuckles’s softness into his mouth. He worked with a desperate, focused dedication, using his tongue and lips to coax blood into the heavy flesh. It was an act of pure worship, of need. He tasted salt and skin and the faint, stale bitterness of his own earlier release. Knuckles groaned above him, a low vibration.
“That’s it,” Knuckles rasped, his hips giving a minute thrust. “Suck your fucking god. Make him hard.”
Tails redoubled his efforts, his jaw aching. Under his ministrations, Knuckles began to stiffen, filling his mouth, then pressing against the back of his throat. The hand in his hair became a vise, holding him firmly in place. Knuckles was fully erect now, a thick, daunting weight on Tails’s tongue.
“Enough,” Knuckles grunted, pulling Tails off by his hair with a sharp, painful yank. “Turn around. On your knees. Against the couch.”
Tails scrambled to obey, his heart hammering. He got on his hands and knees, his backside presented, his face pressed against the musty fabric of the couch cushion. He heard the sick, slick sound of Knuckles spitting into his palm.
There was no preparation. The blunt, wet head of Knuckles’s cock pressed against him, a demanding pressure. Knuckles leaned forward, his enormous, food-laden belly pressing like a hot water bottle against Tails’s back, crushing him into the couch.
“You’re gonna take all of it,” Knuckles breathed, his voice raw with strain and desire.He pushed.
The burn was immediate, a white-hot tear. Tails cried out, the sound muffled by the cushion. Knuckles didn’t stop. He pushed harder, his own body weight providing a relentless, crushing force. Tails felt himself stretch, open, yield. Knuckles sank deeper, an inexorable invasion, until his groin was flush against Tails’s ass, his heavy balls slapping against Tails’s skin.
“Fuck,” Knuckles hissed, pausing, fully seated. His gut was a smothering, sloshing weight. “Fucking perfect. So tight around my cock.” He withdrew, almost all the way, then slammed back in with a force that drove the air from Tails’s lungs.
The pace he set was brutal and functional. Each thrust was a grunting, shoving effort, his body hampered by its own colossal mass. The couch skidded forward an inch with every drive. The sounds were obscene: wet flesh slapping, strained leather groaning, Knuckles’s ragged panting in Tails’s ear.
“You feel that?” Knuckles gasped, his voice trembling with effort. “You feel how fucking deep I am? You’re full of me. Just like I’m full of that food.” He wrapped one thick arm around Tails’s chest, pinning him, his hand coming to rest on the soft swell of Tails’s own stomach. He squeezed. “Getting a little gut on you, too. My cum’s fattening you up from the inside, you slut.”
The words, filthy and possessive, sent a jolt through Tails. His own trapped cock was achingly hard. He was being fucked, filled, and verbally degraded, and it was unraveling him completely. He pushed back against the thrusts, meeting Knuckles’s clumsy, powerful drives.
“Yeah, work for it,” Knuckles snarled. His thrusts became more erratic, losing rhythm, driven by pure, urgent need. “Gonna pump you so full. Gonna breed you like a bitch.”
His rhythm shattered. He hammered into Tails with a series of short, furious jerks, his body tensing like a bowstring. With a choked, guttural roar, he came, surging deep inside. Tails felt the hot, pulsing flood, a claiming warmth that seemed to swell his very core. Knuckles collapsed onto him, a suffocating, sweaty weight, riding out the last waves of his orgasm with shallow, grinding motions.
They lay like that for long minutes, Knuckles’s softening cock still inside him, his weight oppressive. Finally, with a groan, Knuckles rolled off, landing on his back on the floor with a seismic thud. He stared at the ceiling, his chest heaving, his stomach a quaking mountain.
“Clean yourself up,” he muttered, wiping his mouth with the back of his hand. “And get me a shake. The double protein one in the freezer.”
Tails’s walk to his room felt unsteady, alien. His body was a hollowed-out, violated vessel, aching in profound ways. Knuckles’s release was a warm, sticky trickle down the inside of his thigh. The phantom pressure of that immense weight still lingered on his back. He passed the hallway mirror and avoided looking, a reflex of shame.
In the perceived safety of his bedroom, with the door closed, he finally breathed. The silence was a physical relief. He needed to shower, to scrub the smell and the feeling away. He went to his dresser, movements mechanical, and pulled open the drawer for clean boxers.
His standard pair, soft and grey, felt wrong in his hands. He stepped into them and pulled them up. The elastic waistband caught, digging sharply into the flesh of his hips.He tugged. They wouldn’t rise past the curve of his lower belly. He looked down, truly looked.
The soft paunch he’d been acutely aware of was more than that now. It was a definite, rounded swell that pushed outward, disrupting the once-smooth line from his chest to his groin. The love handles he could grab were more pronounced. He sucked in, but the softness remained, stubborn and real. The boxers were simply too small. The waistband cut a red, angry line into his fur and skin.
He let them fall to his ankles, stunned. He turned slowly to the full-length mirror on his closet door.
The reflection was undeniably him, yet transformed. His frame, always slender and lean, now carried a subtle, pervasive softness. His belly curved outward, a gentle, firm dome. His hips were wider, his thighs thicker, their inner flesh rubbing together with a new familiarity. He placed a hand on his stomach, feeling the slight, dense firmness beneath the fur. It wasn't food. It was a deep, internal fullness, a permanent-looking shift. Knuckles’s words echoed in the quiet room. My cum’s fattening you up from the inside.
A frantic, morbid curiosity seized him. He dug through his drawer and found an old pair of jeans, the ones he’d worn just a month ago on a mission with Sonic. He stepped into them. The denim refused to button. He lay back on the bed, sucked in his breath until his lungs burned, and tried to force it. The button hovered an inch from the fly. He released his breath with a defeated gasp, and the denim strained dangerously across his new middle.
He let the jeans fall to the floor, next to the boxers. He lay there on his bed, naked, staring at the ceiling. One hand drifted back to his stomach, resting on the unfamiliar curve. A shudder ran through him—part horror, part a dark, thrilling awe. The proof was undeniable, etched into his very flesh. He was changing. He was being remade.
From down the hall, Knuckles’s voice, a demanding bellow, shook the walls. “TAILS! Where’s my fucking shake?”
Tails closed his eyes. He didn’t move. The red line from the too-tight waistband burned on his skin, a brand.
