Chapter 1: Donuts and Helium
The hangar was a cathedral of cold, humming metal, so vast its ceiling vanished into a gloom pierced by sporadic fluorescent bars. The light fell, clinical and unforgiving, onto the only thing that disrupted the sterile gray: a mountain of donuts on a single, endless table.
Helia Melonowski sat before the sugary avalanche, her breath already coming in short, anticipatory puffs that fogged the chilled air. Towers of glazed, frosted, and jelly-filled spiraled toward the distant ceiling, glistening with synthetic sparkle. The smell was overpowering—cloying vanilla, sharp raspberry jelly, the burnt-sugar scent of frying fat—underlaid by something else, something metallic and alive, like the building itself was breathing.
She didn’t question it. The hunger was a hollow, screaming thing behind her navel. She reached out, her fingers sinking into the yielding sponge of a honey-dipped ring, and brought it to her lips.
The first bite was a sacrament. Sugar crystals shattered against her teeth. The second was a compulsion. The third, a necessity. She ate not with pleasure, but with a frantic, mechanical urgency. Donut after donut vanished. Cream filling smeared her chin. Rainbow sprinkles stuck to the swell of her breasts, which strained against the front of her simple cotton dress.
She could feel it happening, the familiar, shameful rush. As the sugar hit her bloodstream, warmth bloomed low in her belly, a deep, throbbing heat that had nothing to do with digestion. A tingling, prickling sensation gathered in her nipples, tightening them into painful points against the fabric. Then the wetness, the seep. Two dark, spreading patches appeared on the pale blue dress, right over her areolae. Milk. Her body’s stupid, embarrassing response to arousal, triggered now by sheer, gluttonous fullness.
Her belly, once flat and taut beneath her dress, began to curve. It pushed against the table’s edge, a firm, round dome distending the material. She grunted, swallowing a custard-filled chunk whole, and unbuttoned the waistband of her skirt. It made no difference. The flesh continued to expand, skin stretching glossy and tight, her navel protruding like a button on a overstuffed pillow.
She was so full. Achingly, impossibly full. But her hands kept moving. One shoving a chocolate éclair into her mouth, the other already reaching for a powdery cruller.
“I can’t,” she whispered to the empty hangar, cream on her lips. “I can’t eat another one.”
Her hand, contradicting her, picked up a jelly donut. It trembled as she brought it to her mouth. She took a bite. Red, sugary syrup burst and dripped down her wrist. The heat between her legs pulsed in time with her heartbeat. The wet patches on her dress grew larger.
When she finally sagged back, her body was a landscape of bloated curves. Her belly was a huge, taut moon, forcing her thighs apart in the seat. Her breasts, already monumental, had swollen further, heavy and hot and throbbing with unspilled milk. They rested on the shelf of her stomach, the damp fabric clinging. She couldn’t breathe without effort. A low, guttural moan escaped her.
This was when the denial always crumbled. In the quiet, swollen aftermath. The thought slithered in, unwanted but potent: What if I was even bigger?
A metallic click echoed through the space. From slots in the table, thin robotic arms articulated into view, their pincers cold and precise. One darted forward, snatching a pink-frosted donut from a nearby tower.
Helia’s eyes went wide. “No. Wait.”
The arm ignored her. It pushed the donut against her closed lips. She shook her head, a pathetic gesture. The arm was insistent. It shoved, smearing frosting on her mouth. With a sob that was half protest, half relief, she opened up. The donut was crammed inside. She had to chew, to swallow. The moment she did, another arm presented a glazed twist.
“Stop,” she choked out, her voice muffled by dough.
They didn’t stop. They were relentless. One after another, donuts were delivered to her mouth. She was a machine now, a processing plant. Her stomach, stretched beyond any reasonable limit, gave a deep, painful lurch. But beneath the pain, the heat grew. The tingling in her breasts became a maddening itch, a pressure building that needed release.
More clicks, different ones. From beneath the seat, a smooth, black phallic shape rose silently. It was thick, veined, and glistening with some kind of lubricant. It pressed firmly against the soaked crotch of her underwear, then her dress. Helia gasped, arching her back despite the massive weight of her belly. The denial was a thin veil now, tearing.
“Oh, god…”
The dildo pushed. The fabric bunched, then gave. The cold, slick tip pressed against her opening. She was drenched, her own arousal mixing with the lube. It was an obscene, perfect fit. With a slow, hydraulic inevitability, it entered her, filling her utterly. A broken cry echoed in the hangar. Her hands flew to her distended belly, as if to hold herself together.
Then came the hiss. Two segmented tubes, snaking from the undercarriage of the table, sought out the damp circles on her dress. Suction cups latched onto her nipples through the fabric, the sensation sharp and shocking. A third, wider hose, slick and cold, pressed against the tight pucker of her asshole.
She knew what came next. She’d both feared and craved it.
A deep, mechanical vibration shuddered through the table. The dildo inside her began to pistons, a slow, deep, rhythm that punched the air from her lungs. At the same instant, a cool, light gas—helium—flowed through the tubes.
It rushed into her breasts. She could feel it, a bizarre, inflating sensation deep in her mammary tissue. They grew heavier, tighter, the skin burning as it stretched further. The suction cups tugged rhythmically, pulling streams of milk from her that were swallowed by the tubes, making space for more gas.
The hose at her ass breached her, a relentless invasion. The helium poured into her intestines, her colon. Her belly, already monumental, began to inflate further. It was no longer just the solid mass of donuts. It was becoming taut, drum-tight, a vast balloon of flesh pushing her dress to its absolute limit.
A wild, terrified excitement seized her. The rhythmic fucking, the fullness, the inhuman expansion. The words she’d forbidden herself to think boiled to the surface.
“Fuck,” she panted, her head lolling back. “Oh fuck, I’m… I’m getting bigger.”
The moment the words left her lips, a jolt of electric lust seared through her, more intense than anything the dildo could provide. Her back arched violently. The machines sensed it. The pace increased. The helium flow intensified.
“Bigger,” she moaned, her voice trembling. Her tits swelled, pushing the suction cups outward. The seam at the side of her dress split with a sound like a gunshot. “Yes, bigger!”
Her belly pressed against the edge of the table, then began to lift it, the metal groaning. The dildo pistoned into her, hitting a spot that made her vision whiten. The inflation was everywhere now—her breasts, her belly, her ass rounding and expanding, even her thighs pressing outward, swallowing the seat.
“Bigger! BIGGER!” she chanted, the word a prayer and a curse. Each utterance fueled the fire, tightened the coil in her groin. She was a thing of immense, swelling curves, skin glowing and stretched, her long hair fanning out over shoulders that were themselves broadening. The hangar didn’t feel so vast anymore. She was filling it.
The orgasm, when it hit, wasn’t a wave. It was a tectonic event. It ripped through the bloated landscape of her body, making every inflating inch of her spasm. Her chants dissolved into a raw, screaming mantra as she came, her voice echoing off the metal ribs high above.
“BIGGERBIGGERBIGGERBIGGER!”
The robotic arms didn’t care that she was climaxing. They didn’t pause. The moment her screams faded to ragged, helium-tinged gasps, a jelly donut was crammed into her open mouth. She gagged, her swollen throat working to swallow, the sweet goo mixing with her own spit.
The dildo, slick with her juices, never stopped its brutal, perfect rhythm. It hammered into her, each deep thrust coinciding with a renewed, powerful surge of helium. The gas was cold inside her, a shocking contrast to the burning heat of her skin and the frantic pulse of her cunt. It hissed through the tubes, an unending inflation.
Her tits ballooned. The suction cups strained, holding on as the massive orbs of flesh swelled outward, pushing against each other, their surfaces growing tighter, shinier. The sterile hangar air felt cool on the new, stretched skin. Her ass, packed with gas, rounded and lifted, becoming a vast, taut dome that rose off the seat. The metal groaned in protest beneath her.
“Stop… can’t…” she whimpered around a mouthful of cream-filled pastry, but her hips were grinding down onto the fucking machine, meeting every thrust. Another orgasm was already building, a supernova compressed inside her expanding flesh. The words slithered out, fueled by the insane sensation. “I’m getting… oh god, so much bigger…”
The feedback loop was instant. Hearing it, admitting it, made her cunt clamp down on the dildo like a vise. A fresh, vicious torrent of helium shot into her. The table creaked. Her spine pressed against the back of the seat, which was now buckling, the bolts popping free from the floor.
More donuts were shoved into Helia’s mouth, the helium surged into her tits and ass in time with every dildo thrust. Helia orgasmed again and again as she ballooned bigger and bigger. The hanger was becoming smaller and smaller as she GREW more and more, the donuts kept coming and more and more helium was pumped in.
The fluorescent lights, once distant, now seemed closer, glaring directly into her teary eyes. Her shoulder brushed against a cold, vertical beam. She was filling the space. Her mammoth breast, swollen to the size of a comforter, pressed against the endless table, causing a tower of powdered donuts to topple and scatter like falling masonry.
She was a mountain of woman. A landscape of quivering, inflated flesh. The dildo felt smaller now, barely a tease inside her cavernous cunt, but the machines compensated. The thrusts became shorter, harder, jackhammer-fast, thrumming against her molten core. The helium wasn’t just filling her; it was packing her, compressing inside, making her denser, heavier, more immense.
Her belly now filled the entire aisle between table rows. Her ass pressed against the far wall of the hangar. The metal squealed, denting outward. She couldn’t see her own feet anymore—they were buried somewhere beneath the colossal curve of her stomach. All she could see was pale, stretched skin veined with blue, the dark peaks of her nipples lost somewhere in the slope of her breasts, and the endless conveyor of donuts being shovelled toward her by the relentless arms.
Another climax tore through her, this one endless, a rolling seismic event that made her entire body convulse. She didn’t chant the word this time. She screamed it, a raw, deafening roar that shook dust from the ceiling.
“BIGGER!”
The hangar answered. With a final, shuddering hydraulic sigh, the machines pushed everything to its limit. A last, crushing load of helium flooded her. The wall behind her gave way with a metallic shriek.
Silence, save for the drip of something sweet and the low hum of dying mechanics. She filled the broken hangar, a goddess of fullness, immobile, utterly colossal, every cell thrumming with spent, impossible bliss. The last few donuts rolled slowly down the vast incline of her stomach and came to rest in the deep valley of her cleavage.
