Chapter 19: The Bluff Backfires
The flickering bulb in Knuckles’ bedroom cast a nervous, stuttering light. It caught the dust motes swimming in the air, the sheen of old grease on a wrench left on the floor, the empty foil wrappers of protein bars scattered like metallic leaves across the desk. The room was a monument to neglected projects and sustained appetite.
Tails stood by the cluttered desk, a gaming controller in his hand. He was supposed to be syncing it, a mundane task. But the orange flash drive plugged into the console’s side had blinked at him, an accusing eye. Knuckles’s drive. The one he’d said held the ‘archive,’ the one he’d threatened to use.
His heart was a trapped bird in his chest. He shouldn’t. It was a violation. But the memory of Knuckles’s voice in the closet—I think about posting it every day—was a cold knife twisting. He had to know.
He navigated the menus with trembling paws. The folder was there, labeled “BACKUP.” He opened it.
His breath stopped.
There were files. Dozens. Named with dates, timestamps that corresponded to the nights things had happened. His stomach dropped. He clicked the first one.
An error message. File corrupted or format not supported.
He clicked another. Same error. Another. Same. He opened the file properties. Each one was barely a kilobyte in size. Empty shells. Placeholders. The timestamps were all from the same day, artificially generated.
No video. No archive. Just the ghost of one, a bluff carved into digital silence.
The relief that washed over him was immediately scalded by a hotter, sharper emotion: rage. It was a clean, bright fury he didn’t know he could feel. All that shame, that terrified submission, the groveling worship… it was built on a lie. A fucking empty folder.
He pulled the flash drive out, clutching it in his fist until the plastic creaked. Then he turned.
Knuckles was in the room’s only chair, a battered recliner that had long since surrendered to his size. He was trapped in it, a king in a crumbling throne. His belly was a massive dome that spilled heavily into his lap, resting on his thick thighs. His arms, rounded and powerful, lay on the chair’s rests, fingers drumming idly. He was staring at a dead monitor, a bag of cheese puffs open on the shelf of his stomach, his muzzle dusted orange. He looked bored. Sated. Imperial.
“Synced?” Knuckles grunted, not looking over.
Tails didn’t answer. He walked towards him, each step deliberate on the grimy floor. The only sounds were the crunch of a stray circuit board under his foot and the low, steady wheeze of Knuckles’s breathing.
Knuckles finally glanced over, his eyes narrowing at Tails’s expression. “What’s your problem, fox?”
Tails held up the flash drive. He dropped it. It clattered against the floor, skittering under the desk.
“It’s empty,” Tails said. His voice was quiet, flat. “There’s no video. There never was.”
Knuckles’s face went through a series of minute changes: confusion, then dawning comprehension, then a defensive, hardening scorn. He shifted in the chair, which groaned in agony. “So? You still did it. You still liked it.”
“You made me think you owned me.” Tails took another step closer. The cheese-puff dust in the air smelled sickly sweet. “You made me worship you for a fucking ghost.”
“You enjoyed it,” Knuckles sneered, but there was a flicker of uncertainty in his eyes. He was used to Tails shrinking, not advancing. He tried to heave himself up from the chair, a monumental effort of grunting and shifting weight. He only succeeded in making the recliner squeal and tilt back further, pinning him at an angle. He was stuck, belly up, a beached leviathan. “Get me a damn water.”
Tails stared down at him. At the vast, vulnerable expanse of him. The powerful echidna, prisoner of his own mass. The lie had broken the spell. All Tails saw now was flesh. Glorious, excessive, lying flesh.
“No,” Tails said.
Knuckles’s eyes widened. “What did you say to me?”
Instead of answering, Tails climbed onto the chair. He didn’t help. He didn’t offer a hand. He put one knee on the armrest, then the other, straddling Knuckles’s lap. He loomed over the trapped form, his own softer body blocking the flickering light.
“What the hell are you doing?” Knuckles snarled, trying to push him off, but his arms were pinned by the chair’s sides and Tails’s weight. He could only shove ineffectually at Tails’s thighs.
“Showing you what you really are,” Tails murmured. He adjusted his position, sliding backwards, settling his full weight onto Knuckles’s chest and face. He pressed his ass down, the soft fur of his thighs and backside smothering Knuckles’s muzzle completely.
Knuckles’s protests became muffled, frantic grunts. His hands scrambled, patting at Tails’s sides. Tails leaned forward, bracing his paws on the chair’s headrest, grinding himself down. He could feel the hot, wet puff of Knuckles’s panicked breath against his most intimate skin, the frantic movement of his head trying to turn for air. The power was dizzying. It was suffocating. It was revenge.
“You’re just a sack of lard,” Tails hissed, rocking back. “A fat, lying sack of lard who can’t even get out of his own chair.”
He lifted himself slightly, allowing Knuckles a ragged, gasping breath. Knuckles’s face was flushed dark with fury and缺氧, cheese-dust smeared. “I’ll fucking kill you—”
Tails shoved his cock, already hard and leaking, into the deep, hot crevice between the upper roll of Knuckles’s stomach and the massive swell of his chest. It was a tight, suffocating valley of hot fur and solid fat. He rutted into it, a rough, dry hump at first, then spitting into his hand and slicking himself to fuck the groove properly.
“You’re gonna watch,” Tails growled, his composure fracturing into something raw and ugly. He grabbed a handful of the fur on Knuckles’s heaving chest, pinching hard. “You’re gonna watch while I fuck the gut I made. My gut. I made this.”
He set a brutal, punishing rhythm, slamming his hips forward, his cock sliding between the tight, fleshy walls. The sound was wet and obscene, a slap of flesh against flesh, against fur. Knuckles bucked beneath him, but his struggles only drove Tails deeper into the soft, imprisoning fat. He was trussed by his own body, forced to endure it.
“You liked me on my knees?” Tails panted, driving harder. “You liked me serving you? Look at you now. You’re just a fucking flesh-hole. A warm, fat place for me to get off. That’s all you’re good for.”
Knuckles’s insults had died. His furious挣扎 had lessened. His breaths were coming in sharp, ragged pulls, but his eyes were locked on where their bodies met, on Tails’s cock disappearing again and again into the folds he had created. A strange, choked sound escaped him—not a protest. It was a groan.
Tails saw it. The denial in Knuckles’s eyes was melting, replaced by a dazed, horrified arousal. The echidna’s own dick was stiffening, trapped under the immense weight of his belly, beading with moisture at the tip.
The sight of it, the ultimate surrender, tipped Tails over the edge. “Yeah, you fat fuck,” he spat, his rhythm becoming erratic, frantic. “You love it. You love being used. You’re nothing.”
With a final, deep thrust that buried his entire length in the soft, hot prison of Knuckles’s body, Tails came. He cried out, a sharp, broken sound, spilling his release over the sweaty fur of Knuckles’s chest and stomach, marking the very mass he’d helped create.
He collapsed forward, spent, his face pressing into Knuckles’s shoulder. For a long moment, there was only the sound of their harsh breathing and the persistent buzz of the dying lightbulb.
Then, beneath him, Tails felt it. A hot, pulsing wetness spreading against his own thigh. Knuckles had come too, silently, helplessly, crushed beneath his own weight and Tails’s assault.
Tails pushed himself up, off the chair. He stood on shaky legs, looking down at the wreckage in the recliner. Knuckles was a mess of come, sweat, and orange dust, his chest heaving, his eyes wide and fixed on the ceiling. The lie was gone. Something else, terrifying and true, had taken its place in the flickering half-light.
Something else, terrifying and true, had taken its place in the flickering half-light.
A month passed in a blur of routine and relentless expansion.
Every morning, Tails would check on Knuckles. The echidna hadn’t left the recliner, not once. It had become his entire world, a creaking prison he no longer tried to escape. Tails would arrive with a monstrous, lidded tub– a industrial-sized thing meant for bulk storage, now filled with a thick, beige slop.
“Lunch,” Tails would say, his voice devoid of its old nervousness.
The slop was a high-calorie cement of blended pasta, ground beef, heavy cream, mashed potatoes, and melted cheese. It smelled of salt and congealed fat. Tails would lift the lid, and the room’s permanent odor of sweat and defeat would be overwhelmed by the greasy aroma.
“I’m not hungry,” Knuckles would grunt, the first week.
Tails wouldn’t argue. He’d just dip a large serving spoon in, bring a glistening mound to Knuckles’s lips, and wait. Knuckles would turn his head. Tails would let the sludge drip onto the echidna’s chest, sliding down the vast curve into the fur. The waste, the mess of it, seemed to bother Knuckles more than the coercion. By the third day, he opened his mouth.
The sound of his eating was obscene: wet, smacking, gulping swallows as he consumed quart after quart. Tails watched, a queer tightness in his own gut, as Knuckles’s stomach visibly distended, pushing further into his lap, straining the fabric of his sweatpants until the waistband vanished beneath the overhang. He’d feed him the entire tub. Sometimes two.
Every afternoon, Tails would return. Knuckles would be sleeping, a mountain of flesh rising and falling with labored breaths. The recliner’s frame was bowing, its joints screaming under the sustained, increasing load. The room’s single bulb had finally died, leaving them in a perpetual, gritty twilight broken only by the glow of a forgotten computer monitor.
When Tails got horny, which was often, he’d simply unzip his pants.
He’d approach the sleeping form. Knuckles’s navel, once a shallow dip, was now a deep, fleshy pit, stretched wide by the pressure of the gut above and below it. The fur around it was matted, damp with old sweat and bits of dried slop.
Tails would spit into his palm, slick his cock, and without a word, press the head against that deep, warm hole. It wasn’t sex. It was utility. He’d shove himself inside, fucking the tight, clinging channel of Knuckles’s belly button with short, brutal strokes.
Knuckles would jolt awake with a choked gasp. “The fuck–?”
“Shut up,” Tails would breathe, pounding into the soft, yielding flesh. “It’s a better hole than your mouth.” He’d grab the heavy roll of fat that spilled over the chair’s side, kneading it like dough, using it to steady his rhythm. He’d come inside that deep, personal crevice, his release lost in the dark, humid depths. Knuckles would just lie there, taking it, his own traitorous cock stiff and leaking onto his stomach.
Other times, Tails would fuck the groove between Knuckles’s immense gut and his chest, or the soft, sensitive area under his arm where fat gathered in a thick roll. He used Knuckles’s body like a living fleshlight, a warm, fat receptacle for his frustration and his twisted, blooming need.
The changes were not incremental; they were geological.
Knuckles’s arms became pillars, so thick they could no longer rest comfortably on the chair. They lay palms-up on the mountainous slopes of his own sides, fingers half-buried in fur. His chest was a hanging shelf, his pectorals not defined muscle but great, soft swells that merged seamlessly with the planet of his stomach. His face was wider, rounder, his neck now just a tapering cone of fat that sank into his shoulders.
He was colossal. Immobile.
The day the scale arrived, Tails had to clear a path through the debris. It was a industrial floor model, digital. He wrestled the recliner, with Knuckles in it, onto the platform. The echidna grunted, a sound of pure strain, as the chair lurched. The number on the display flickered, stabilized.
800.4 pounds.
They both stared at the glowing red digits. The silence was absolute, broken only by Knuckles’s wet, whistling breath. He looked from the number to his own body, a landscape he no longer recognized. He tried to shift, to lean forward, but the weight was absolute. His body would not obey. A low, pathetic noise escaped him.
Tails looked at the number, then at the helpless giant before him. A strange, cold serenity settled over him. He placed a hand on the dizzying curve of Knuckles’s stomach, feeling the heat, the tight-stretched skin, the sheer, impossible tonnage of it.
“Mine,” Tails said, the word final in the dark room.
The red glow of the scale’s numbers painted their faces in hellish light. 800.4. The digits seemed to float in the darkness between them, a verdict.
Knuckles made a sound like a leak slowly deflating. His fingers, bloated and stiff, twitched against the vast expanse of his own hip. He couldn’t see his own feet anymore. The recliner’s frame emitted a low, continuous groan of structural despair.
“Get me off this thing,” Knuckles whispered. It wasn’t a command. It was a plea, airy and thin.
Tails didn’t move his hand from the burning hot dome of Knuckles’s stomach. He could feel the frantic, rabbiting heartbeat within, trapped under layers of fat and fear. “Why?”
A long silence. The computer monitor’s glow outlined the dust swimming in the air.
“I need to piss,” Knuckles admitted, the words choked with shame.
Tails considered this. He looked from the pitiful, water-heavy sloshing of that immense gut to the far side of the room, where Knuckles’s unused bed lay under a mound of discarded tools and laundry. A plan, cold and precise, crystallized.
“Alright,” Tails said, his voice oddly gentle. It was the tone he used for complex engineering problems. He stepped off the scale and grasped the sides of the recliner. “You’re going to help. Push.”
It was a pathetic, agonizing process. Knuckles strained, his face purpling, every muscle in his body screaming to shift the inertia of his own form. Tails pulled, his boots slipping on the grimy floor. The recliner inched backward with torturous slowness, its legs scraping twin scars into the wood. With a final heaving shove from Knuckles that was mostly a full-body tremor, the chair cleared the scale.
“Now stand,” Tails said, wiping sweat from his brow.
Knuckles tried. He planted his palms on the chair’s arms, the fat of his forearms squeezing against the vinyl. He pushed. A vein throbbed in his temple. A sharp, pained grunt burst from him. He rose maybe three inches before collapsing back, the impact making the whole chair bounce. The smell of his desperate sweat filled the space between them.
“I can’t,” he breathed, his eyes wide with a panic that was entirely new.
“You will,” Tails stated. He moved behind the chair. “Or you’ll piss yourself right there. Again.” He wrapped his arms under Knuckles’s immense, soft armpits, his face pressing into the damp, musky fur of his back. “On three. One. Two.”
It was less a lift and more a brutal excavation. Tails hauled backward with everything he had, his muscles burning. Knuckles, with a guttural roar of effort, pushed. He came up out of the chair like a ship breaching, unstable and monumental. He swayed, his tree-trunk legs trembling violently under the unfamiliar task of supporting all that weight. He panted, a high, whining sound in his throat.
“The bed,” Tails directed, his voice strained from the effort. He kept a firm, pushing hand on the small of Knuckles’s back, which was now just a convex curve above the staggering swell of his ass.
The five steps to the bed were a marathon. Knuckles shuffled, each foot dragging as if through mud, his breath a ragged sob. He clutched at his own stomach, as if trying to hold the colossal weight up to ease the crushing pressure on his pelvis and spine. When his knees hit the edge of the mattress, he simply folded forward with a groan of relief, his upper body collapsing onto the rumpled sheets.
He lay there, half-on half-off, heaving. His huge ass was in the air, pressed against Tails’s thighs. The sweatpants, strained beyond all reason, were a damp, frayed nightmare barely containing him. The cleft of his ass was a deep, shadowed valley between two immense, quivering hills of fat.
Tails looked down at the presented form. This wasn’t the powerful echidna pinning him in a closet. This was a broken, bloated thing, gasping on the edge of its own bed. The power was absolute, and it tasted metallic.
He didn’t bother with the sweatpants. He took the multitool from his belt, flipped open the blade, and neatly slit the strained fabric from waistband to seam. The pants fell away like a shedding skin. Knuckles’s ass was bare, huge, pale where the sun never touched, furred with a fine, dark red down. Tails spat onto his fingers, then reached down and shoved two of them, dry and rough, into the tight, clenched ring of muscle between Knuckles’s asscheeks.
Knuckles jolted. “Don’t–”
“Don’t what?” Tails asked, working his fingers in, feeling the tight, hot resistance. “You’re just a hole. You proved that when you came in your own lap while I fucked your navel. This is just a different hole.” He added a third finger, scissoring them brutally. “A tighter one.”
He unzipped his own flies, his cock springing out, already hard and angry. He spat into his palm again, slicking himself roughly. He positioned the swollen head against Knuckles’s entrance, which gave only the faintest, reluctant yield under the pressure.
“You wanted me to serve you,” Tails hissed, leaning his weight forward. He grabbed two massive handfuls of Knuckles’s ass, the flesh overflowing between his fingers, and pulled the cheeks apart. “Now you serve me. You hold this gut up so I can fuck the shame out of you.”
With a brutal, unforgiving thrust, he sheathed himself inside. Knuckles cried out, a raw, shredded sound muffled by the sheets. It was impossibly tight, a searing, clenching heat that fought him every inch. Tails set a punishing rhythm from the start, each drive of his hips slamming Knuckles’s immense weight forward into the mattress, making the bedframe shriek in protest against the wall.
“You’re nothing but fat and fuck-holes,” Tails grunted, the sweat dripping from his muzzle onto Knuckles’s broad, heaving back. “You can’t run. You can’t fight. This,” he hammered home, “is all you’re for now.”
Knuckles sobbed. But his body, that traitorous, hungry mass, began to respond. His ass pushed back, meeting Tails’s thrusts with a weak, eager shove. A wet spot spread on the sheets beneath his belly—his own cock, trapped and leaking, untouched.
“Yeah,” Tails sneered, feeling the clench around him grow purposeful. “You fat fucking pig. You love it. Admit it.”
Knuckles turned his head, one cheek pressed into the mattress. His face was a ruin of sweat and tears. “I… I…”
“Say it!”
“I love it!” Knuckles wailed, the confession torn from him. “I’m a fat pig, I love it, I love it, please—”
The begging undid Tails. He fucked into him with a final, chaotic frenzy, his orgasm ripped from him in hot, pulsing jets deep inside Knuckles’s bowels. As he came, he felt Knuckles’s whole massive body convulse, a second, wetter heat soaking the sheets beneath them as the echidna followed him over the edge, untouched, broken by words alone.
Tails pulled out, a soft, obscene sound in the quiet. He stepped back, fastening his pants, his breath slowing. Knuckles remained collapsed over the edge of the bed, a spent, shuddering mountain. The smell of sex, sweat, and sharp urine filled the room.
Tails looked at the scale, its red light still on in the corner. Then he looked at the ruined form on the bed. He walked to the door, picking up the empty nutrient tub.
“I’ll make more,” he said, not looking back. “You need to keep your strength up.”
