Chapter 1: The First Twitch
Bree’s morning stretch usually ended in a serene, deep release, her muscles lengthening and softening under the warm sun streaming through the windows. Today, it ended with a sharp, peculiar pressure digging into the mat between her thighs.
She froze, mid-cobra pose, the pleasant burn in her lower back forgotten. It was a firm, insistent presence, trapped beneath the sheer fabric of her lavender yoga pants. Not a cramp. Something… structural.
“Okay, what the hell,” she murmured to the empty, sunlit room. She pushed herself up onto her knees, her long blonde ponytail swinging over her shoulder. With deliberate slowness, she hooked her thumbs into the waistband of her pants and peeled them down.
Her breath hitched.
There, nestled in her blonde curls, was a thick, flaccid length of flesh that most certainly had not been there when she’d shaved two days ago. It was dusky pink, ruddy, and unmistakable. A shaft. Perfectly formed, and even as she watched, seemingly inert, it gave a subtle, twitching pulse.
“No,” she whispered, but the word held no horror. It was pure, electrifying disbelief.
Her hand moved without conscious command. Her fingers, usually so sure and strong from lifting weights, trembled slightly as they brushed against the skin. It was warm. Softer than she expected. A jolt, stark and undeniable, shot up from the point of contact straight to her core, making her gasp. Her nipples tightened against her sports bra. A familiar, low heat began to pool in her abdomen, but it was magnified, intensified, as if this new thing was a lightning rod for sensation.
She wrapped her hand around it. A full, shuddering sigh escaped her lips. It was hers. The realization was a tremor that moved from her gut to her throat. She gave an experimental, gentle stroke.
Another pulse, stronger this time. It twitched in her grip, filling, lengthening ever so slightly. The heat in her belly surged into a blaze. This wasn’t frightening. It was… fascinating. Potent.
A knock at the front door made her jerk her hand away as if scalded.
“Bree? You in there?” The voice was muffled, timid. Derrick.
A slow smile spread across her face, replacing the shock. Her heart wasn’t hammering with panic; it was pounding with a new, fierce curiosity. She yanked her yoga pants back up, the strange new weight a fascinating secret against her leg. She didn’t bother with a robe. Her tight tank top and pants were coverage enough. More than enough.
She opened the door, leaning against the frame. Derrick stood on her porch, looking as he always did—like a nervous, overgrown kid. His soft, rounded frame was swallowed by a faded band t-shirt, his fingers worrying the edge of a sealed envelope.
“Hey, Derrick.” Her voice was a notch lower than usual, smoother.
He blinked, his gaze doing its usual frantic dance—a micro-second on her face, a skipped beat over her shoulders, a panicked jump to the porch swing. “Uh, hi. Mail guy put this in my box by mistake. It’s for you.” He thrust the envelope out.
“Thanks.” She took it, letting her fingers linger against his. He flinched. “You’re sweet to bring it over. Want to come in? I just made coffee.”
“Oh, no, I couldn’t—I mean, I shouldn’t intrude…”
“You’re not.” She turned and walked inside, leaving the door wide open. An invitation he was too polite, too lonely, to refuse.
She heard his hesitant shuffle behind her. The door clicked shut. She went to the kitchen, acutely aware of the new heaviness between her legs with every step. She poured two mugs, her movements deliberately languid.
“Vanilla creamer, right?” she called.
“Y-yeah. Thanks.”
When she brought the mugs to the living room, he was perched on the very edge of her couch, trying to make himself small. She sat right next to him, the cushion dipping, her thigh not quite touching his. She felt hyper-aware of everything—the scent of her vanilla candle, the dust motes dancing in the sunbeam, the rapid, shallow rhythm of Derrick’s breathing.
“So,” she said, sipping her coffee. “How’s the writing going?”
He shrugged, staring into his mug. “Slow. Kind of blocked.”
“Maybe you need a distraction.” She let her free hand fall onto the couch cushion, her pinky finger barely grazing the fabric of his shorts. He went perfectly still. “Maybe you need someone to tell you what to do.”
His head snapped up, his eyes wide behind his glasses. There was fear there, yes, but beneath it, a spark she’d always suspected. A deep, thirsty glimmer.
She pressed on, her voice a confidential whisper. “You know what I think? I think you work too hard. You forget to enjoy things.” She leaned forward, putting her mug on the table. As she settled back, she let her arm drape along the back of the couch, behind his shoulders. “When was the last time you really indulged?”
He swallowed. “I… I don’t know.”
“I have donuts,” she said, as if unveiling a grand plan. “The big, frosted ones from that place you like. Someone brought them to my book club. I was just going to throw them out.”
A war played out on his face. Want warred with shame. “I shouldn’t.”
“Why not? One little treat. As a thank you for bringing my mail.” She stood and glided to the kitchen, returning with the box. She opened it under his nose. The sweet, greasy scent filled the space between them. She picked up a chocolate-glazed one, heavy and gleaming. “Here.”
He looked from the donut to her face, his resolve crumbling. He took it. A small, helpless sound escaped him as he took the first bite, a shower of crumbs dusting his shirt. His eyes closed for a second in pure, guilty pleasure.
Bree felt a corresponding thrill pierce her own core. It was sharp, immediate. A tight, pulling sensation low in her belly, and a distinct, thickening pressure in her yoga pants. She shifted slightly, savoring it. Watching his clumsy, eager bites, the way his jaw worked, the slight bloating of his already soft belly under his shirt… it did something to her. Arousal, yes, but it was darker, more possessive. It was hunger.
He finished the first donut, licking sugar from his thumb. He looked dazed, pliant.
“Have another,” she said. It wasn’t a suggestion.
He didn’t hesitate. He took a maple-bacon one this time. She watched, mesmerized, as he ate. With every bite, every swallow, the heat within her coalesced, tightened, spiraled. The new part of her was fully awake now, a rigid, urgent weight against the constricting fabric. She had to cross her legs to contain the sensation, the movement pulling a soft groan from her lips.
Derrick’s eyes flew to hers, questioning, his mouth full.
“They’re that good, huh?” she breathed, her voice thick.
He nodded, chewing slowly now, his gaze locked on hers. He understood, on some level, that this was no longer about pastries. The air crackled, thick with sugar and something else—ozone, and power.
She let him finish the second donut. His breathing was heavier. A faint sheen of sweat glistened on his forehead. He looked blissful, stuffed, and utterly under her spell.
“Good boy,” she purred.
The words, and the blatant look of submission that flooded his features, were the final trigger. The coil inside her snapped.
Pleasure, raw and seismic, ripped through her. It was unlike any orgasm she’d ever had—deeper, more conquering. It centered in her pelvis but radiated outwards, making her toes curl and her spine arch. A choked sound escaped her, part sigh, part growl. Her hands gripped the couch cushions, and for a few seconds, the world was pure, white-hot sensation.
As the waves subsided, leaving her trembling and breathless, she became aware of new, profound changes. Her sports bra was now painfully tight, the fabric straining across her chest. The muscles in her arms and thighs felt denser, fuller, stretching her skin. And between her legs… the presence was massive, a throbbing, spent weight that demanded space.
Derrick stared, his face a canvas of awe and confusion. “Bree… you… you just…”
“I know,” she said, her new voice even richer, a resonant alto that vibrated in her own chest. She uncoiled herself from the couch, her movements inherently more powerful, more graceful. She walked to the large mirror on the far wall, her reflection drawing her forward.
The woman—the being—staring back was both familiar and utterly alien. She was taller. Her shoulders were broader, the deltoids sharply defined beneath her tank top straps. Her bust, always generous, now strained the Lycra fabric to its limits. Her waist seemed smaller in contrast, her hips more pronounced. And her face… it was hers, but sharper, more formidable. The blonde hair seemed brighter.
But her eyes held the most profound change. The playful confidence was still there, but it had been forged into something harder, hungrier, utterly unapologetic.
She glanced over her shoulder at Derrick, who still sat, looking bloated and enthralled on her couch.
A slow, triumphant smile touched her lips.
This was just the beginning. And she knew exactly what, and who, she needed for the next phase.
And she knew exactly what, and who, she needed for the next phase.
The silence in the sunlit room was heavy, charged. Derrick hadn’t moved from the couch. He just stared at her expanded reflection in the mirror, his mouth slightly open.
Bree turned from her reflection, the motion smooth and predatory. “You liked that, didn’t you?” she asked, walking back toward him. Her new height made the room feel smaller. “Watching me. Knowing you caused it.”
“I… I don’t understand what happened,” he managed, his voice thin.
“You fed me,” she said simply, stopping in front of him. She looked down at his soft, prone form. A fresh, jagged spike of desire cut through her post-orgasmic haze. It was aimed directly at him, at his helplessness, at the faint dusting of powdered sugar on his lower lip. “Now it’s my turn.”
Her meaning hung in the air for three long heartbeats before his eyes widened in dawning, terrified comprehension. He shook his head, a weak, reflexive denial, but he didn’t get up. He didn’t run.
“Bree, I can’t…”
“You can.” Her tone brooked no argument. It was a fact. She reached down, her hands—larger now, stronger—closing around his wrists. She pulled him to his feet with disturbing ease. He stumbled against her, his soft belly pressing into the new, firm muscle of her abdomen. A shudder ran through him. She smelled the sugar on his breath, the faint salt of his nervous sweat. It was intoxicating.
She guided his hand, forcing his pudgy fingers to brush against the formidable bulge in her yoga pants. He gasped. “That’s you,” she whispered into his ear. “Your reward. And mine.”
He was painfully, obviously hard. The evidence pressed against the fly of his khaki shorts. His shame was a tangible thing, but beneath it ran a current of raw, desperate hunger.
“On your knees, Derrick.”
He sank down without another sound, the old floorboards creaking under his weight. He looked up at her, his glasses slightly askew, his entire world narrowed to the space between her and him. She hooked her thumbs into her waistband and pushed the fabric down, letting her cock spring free.
It was thicker now, impressively so, a ruddy, full length of flesh that curved slightly upward. A bead of moisture already gleamed at the tip.
Derrick’s breath hitched. He didn’t move.
“Go on,” she coaxed, her voice dropping to a velvet murmur. “Taste what you made.”
He leaned forward, hesitant, then closed his mouth over the head. The sensation was a bolt of pure, incandescent lightning. Bree’s head fell back, a sharp curse hissing between her teeth. His technique was clumsy, unpracticed, but the utter submission of the act, the visual of him on his knees, his cheeks hollowing… it was better than skill.
She let him work, her hands tangling in his hair, not guiding, just possessing. She watched the top of his head bob, felt the hot, tight pull of his mouth. Pleasure built in a slow, relentless tide. But she was learning the rules now. This wasn’t for her climax.Not yet.
After a few minutes, she tightened her grip in his hair and gently pulled him off. A string of saliva connected his lip to her glistening flesh. He looked wrecked, dazed, his own need straining against his zipper.
“Good,” she breathed, her own pulse roaring in her ears. “So good for me.” She pulled her pants up, the sensitive flesh aching with neglect. The denial made it throb more. “Now you need your strength.”
She led him, compliant and silent, back to her kitchen. She sat him at the small table and began pulling things from the fridge: leftover fettuccine alfredo, a tub of potato salad, a container of fried chicken. She microwaved the pasta until the cream sauce bubbled, the rich smell of garlic and cheese filling the room. She piled a plate obscenely high, a mountain of carbohydrates and fat.
She set it in front of him with a fork. “Eat all of it.”
He looked at the plate, then at her, a silent plea in his eyes.
She leaned over him, caging him against the table, her new body blocking the light. “Every.Single. Bite.”
He picked up the fork. The first few mouthfuls were slow. Then, as if a switch flipped, a frantic urgency took over. He shoveled the pasta in, gulping, chewing thickly. He moved on to the potato salad, spooning great creamy globs into his mouth. He gnawed on the chicken, grease shining on his chin. His breathing grew labored, but he didn’t stop. His soft middle pressed tighter against the edge of the table.
Bree watched, one hand idly stroking herself through her pants. Her arousal was a live wire, sparking with every gulping swallow he took. The visible expansion of his gut, the little grunts of overfullness, the complete surrender to gluttony—it was the most erotic thing she’d ever witnessed.
When the plate was clean, she produced a giant, frosted cinnamon roll, sticky and cold from the fridge. “Last one.”
A pained, grateful noise escaped him. He peeled it apart with his fingers and devoured it, the icing smearing across his cheeks. He finished, slumped in the chair, his belly a pronounced dome that strained the fabric of his shirt. He could only breathe in shallow, sharp pants.
Bree was burning up. The need was a physical ache, a demand. She couldn’t wait.
“Go home, Derrick,” she said, her voice rough.
He blinked, slowly, struggling to process the command. He managed to heave himself up, moving with a weighted, ponderous slowness. He waddled to her door, flushed and stupefied, and let himself out.
The moment her door closed, Bree was on the living room floor. She didn’t make it to the couch. She shoved her pants down and her hand closed around her cock. It filled her grip, hot and iron-hard. This time, she didn’t tease. She thought of Derrick’s bloated stomach, of his plaintive eyes, of the sugary, greasy feast disappearing into him. She remembered the feel of his mouth.
Her orgasm took her fast and brutal, bending her spine on the polished hardwood. A guttural cry ripped from her throat. She pulsed in her own fist, waves of punishing pleasure radiating outwards.
As the sensations ebbed, the changes followed. She felt the familiar tightening in her shoulders, the expansion in her chest. She looked down. Her hand, still wrapped around her shaft, no longer covered the full length. There was a significant, thickening inch of flesh extending beyond her fist.
A triumphant laugh, low and dark, bubbled up from her chest.
The pattern cemented itself over the following week.
He would come over, timid and eager, under some flimsy pretense. She’d have him on his knees first, his mouth a warm, wet instrument of her will. She’d let him service her until her control frayed, then deny herself, pushing him away at the last possible second. The aching deprivation only fueled the fire.
Then, the feeding.
She became a culinary tyrant. She ordered him large meat-lover’s pizzas and watched him eat the entire thing, slice after grease-slick slice. She baked trays of gooey macaroni and cheese, rich with heavy cream and three types of cheese, and fed him spoonfuls until he begged for a break with his eyes. She whipped gallons of whole cream with sugar and vanilla, forcing him to drink it like milk. She fried stacks of pancakes drowning in syrup and butter for breakfast.
He never refused. His resistance had melted away that first day, replaced by a dedicated, feverish obedience. His body documented their pact. His face grew rounder, his jawline softening into his neck. His arms grew heavier, his movements more deliberate. But the most dramatic change was his stomach. It began to protrude in a smooth, firm curve, a planet of his own making.
After each session, swollen and drowsy, he would waddle next door. And Bree would lock her door, slide down against it, and bring herself to a furious, screaming climax alone on the hall floor, visions of his distended belly flashing behind her eyelids.
Each time, she grew.
Her shoulders broadened, stretching the seams of her tank tops. Her biceps and quadriceps developed dense, hard curves that her old leggings could barely contain. Her chest became so full she stopped wearing bras altogether; they were useless. Her cock, which she measured in the stark light of her bathroom mirror with a cold, clinical focus, lengthened. It filled out, gaining impressive girth.
Then, one evening, after a particularly extensive bout where Derrick had consumed an entire family-sized pot of beef stroganoff followed by a half-gallon of rocky road ice cream, he left. He moved with a slow, wide-legged gait, his breath audible from across the room. The hem of his t-shirt, an old grey thing, had ridden up over the lower curve of his stomach, exposing a strip of pale, taut skin above his waistband. It stayed there, unable to fall back down over the new, permanent slope of his gut.
Bree closed the door. The familiar, frantic need took her. She didn’t make it to the floor. She just stood there, in the middle of her living room, her hand shoving into her shorts. She gripped herself, ready for the swift, familiar release.
Her fingers met. Her thumb touched the base of her knuckles.
She stopped.
She looked down. Her hand, now large and powerful, was wrapped fully around the thick base of her cock. It was a perfect, firm circle of fingers and palm. The shaft extended well beyond her grip, proud and veined and utterly her own.
She stood there for a long moment, holding herself, watching the last of the sun glint off the sweat on her powerful forearm. From next door, through the thin wall, she could just hear the low, contented groan of a man sinking into a couch, overfull and owned.
She smiled. It was a beautiful beginning.
It was a beautiful beginning.
The routine became their religion. Derrick’s quiet, lonely life next door dissolved into a single purpose: to come, to consume, and to obey. The door between their units might as well not have existed. He’d let himself in now, his key a symbol of his surrender, usually around three in the afternoon, after Bree’s workout. The sounds of her lifting—the clank of plates, her ragged, powerful breaths—were his call to prayer.
She was changing, daily. He saw it in the way her shoulders now filled doorways, in the new, rolling strength of her gait. He felt it in the growing, formidable weight of her hands on his head. He heard it in her voice, a resonant alto that seemed to vibrate in his own bones.
But his own transformation was more visible, more quantifiable. The scale in Bree’s bathroom told the story. It was a digital, industrial-looking thing she’d ordered just for him. He stood on it every time, after the feeding, his heart pounding with a mixture of dread and a weird, thick pride.
Three hundred. Three-twenty. Three-fifty.
His body was a monument to her will. His stomach was a vast, hemispheric shelf that rested on his thighs when he sat. His chest softened into subtle breasts, his arms were thick pillars of fat that swayed when he moved. His face was a pleasant, wide moon, his neck a strong column that merged seamlessly with his jaw. His clothes were all new, ordered online in silent, shameful batches—soft, stretchy fabrics in dark colors that did little to hide the monumental truth of him.
Then, one Tuesday, the digital numbers blinked and settled.
402.4
A strange, soundless silence filled the bathroom. Bree stood behind him, a towering presence reflected in the mirror. Her smile started slowly, a curl at one corner of her mouth that spread into a full, radiant expression of pure, unadulterated triumph.
“Four hundred,” she breathed. The words were warm against the back of his ear. “You gorgeous thing. You beautiful, perfect thing.”
Her hands, each now large enough to span his lower back, slid around his immense sides, over the dense curve of his belly, and locked together in front of him. She hugged him from behind, pressing her formidable chest into the soft roll of his back. He shuddered, leaning into the embrace, his own arms too short now to reach around and hold her.
“You deserve a reward,” she murmured, her lips brushing his ear. “A real one.”
She guided him, not to the feeding chair, but to her bedroom. The afternoon sun slanted across her bed. “Lie down,” she said, her voice gentle but firm.
He did, the mattress groaning profoundly under his weight. He sank into it, his bulk spreading, his breathing already labored from the short walk. He watched her, eyes wide behind his glasses, as she stood at the foot of the bed. Instead of undressing herself, she leaned over him. Her fingers went to the button of his trousers, then the zipper.
“Let me,” she said, and her tone held a tenderness he’d never heard before.
She peeled the elastic-waisted pants down, along with his underwear, freeing him. He was, as always, painfully erect, jutting up from a nest of coarse hair against the pale, immense landscape of his stomach. She looked at him, and her smile turned predatory again, but softer.
“My turn to say thank you,” she said.
Then she lowered her head.
The sensation was so unexpected, so utterly alien, that Derrick cried out. Her mouth was hot, wet, and impossibly skilled. There was none of his own clumsy desperation. This was a slow, luxurious conquest. She took him deep, her throat working, her hands kneading the heavy flesh of his lower belly. He whimpered, his own hands fisting in the sheets, his hips making small, helpless thrusts into that divine, sucking heat. It was over embarrassingly fast for him, a rushing, shuddering climax that left him gasping and spent, collapsing back into the mattress like a deflating balloon.
Bree lifted her head, licking her lips with a thoughtful expression. She then stood up, looking down at his bloated, sated form. Her eyes glittered.
“But I’m not finished thanking you,” she said.
Her hands went to the waistband of her own shorts—simple grey sweatpants. She pushed them down, along with her underwear, in one smooth motion.
Derrick’s breath caught.
There, standing proud and thick from a thatch of blonde curls, was her cock. It was fully five inches of rigid, veined flesh, flushed a deep pink, gleaming slightly in the slanted light. It was a fact. A weapon. A gift.
She climbed onto the bed, kneeling over his face. The mattress tilted under her weight, too. She was substantial, a mountain of muscle and power above him.
“Open up, Derrick,” she commanded, her voice husky.
He obeyed, his mouth falling open. He didn’t have a frame of reference, only a deep, submissive need to please.
She didn’t gentle him into it. She guided herself with one hand, and with a slow, inexorable pressure, began to feed her length into his mouth. It was wider than he expected, stretching his lips, filling him. He gagged instinctively, his eyes watering.
“Relax,” she soothed, her other hand stroking his hair. “Just take it. For me.”
He forced his jaw to go slack, his throat to open. She slid deeper, the head bumping the back of his throat. Then she began to move. A slow, rhythmic fucking of his face. In, out. In, out. The world narrowed to the salt-and-skin taste of her, the overwhelming fullness, the muffled, wet sounds, and the magnificent, terrifying sight of her above him—her defined abdomen clenching, her immense breasts swaying with each thrust, her expression one of focused, blissful ownership.
He surrendered completely, becoming just a vessel, a warm, willing hole for her use. His own body, all four hundred pounds of it, seemed to disappear. There was only her.
Her pace increased. Her breaths became sharp, urgent pants. “That’s it… just like that… you perfect, fat… fuck…” The words were broken, guttural.
With a final, deep grind that buried her to the hilt in his throat, she stilled. A raw, torn cry ripped from her lungs. He felt her throb, pulse, and then a sudden, hot flood filled his mouth. It was surprisingly copious, thick, and sweet—almost cloyingly so, with a sharp, alkaline undertaste.
The instinct to gag was overpowering, but a sharper instinct took over. To please. To consume. As she pulled out with a slick pop, he swallowed convulsively, greedily, gulping down every last drop of her.
She collapsed sideways onto the bed beside him, spent, one powerful arm thrown over her eyes. For minutes, the only sound was their ragged breathing and the groan of the settling mattress.
Then, the changes began.
For her, it was the familiar symphony of expansion—the subtle lengthening of limbs, the tightening of skin over new muscle, a fresh, heavy density in her chest and between her legs. She sighed, satiated.
For him, it started as a warmth. A profound, internal heat that spread from his gut outward. Then came the rumble, a deep, gurgling churn that was audible across the room. He gasped, his hands flying to his stomach.
“Bree… something’s…”
Before their eyes, the vast curve of his belly began to distend further. It wasn't bloat. It was a rapid, steady inflation, as if being pumped with air. The skin, already stretched shiny, grew tighter, straining against itself. The roll of fat over his hips swelled, merging into his thighs. His face, still damp with sweat and spit, grew palpably fuller, his cheeks rounding, his chin doubling.
He groaned, a sound of overwhelming fullness, but there was no pain. Just an immense, heavy pressure, a rapid, shocking accumulation. The bed creaked in protest as his form settled into a new, even more massive configuration.
Bree sat up, staring. Her post-orgasm haze evaporated, replaced by razor-sharp focus. She climbed off the bed and stood beside it, looking down at him.
A slow, dawning comprehension widened her eyes. She looked at his body, still subtly shifting, then at her own hands, then back at him.
“My cum,” she whispered, awe and delight twisting together in her voice. “It’s not just me. It feeds you. It fattens you.”
She commanded him to stand. It was a struggle. He rolled, heaved, and with her surprisingly strong hand under his arm, managed to get to his feet. He felt enormously, ponderously different. Denser. The room seemed smaller.
“Come here,” she said, leading him back to the bathroom scale.
The numbers blinked, searching for equilibrium.
414.8.
Ten pounds. At least. In minutes.
But the final revelation came when she turned him to face her, placing her hands on his broad, soft shoulders. For months, she had been looking up at him. Even as she grew, his height and his bulk had made him seem larger.
Now, her eyes met his directly.
Then they traveled past his, looking slightly down.
She was taller. Not by a lot. An inch, maybe two. But it was undeniable. The top of his head was level with her eyebrows.
The power dynamic, already absolute, finalized itself in their very anatomy. A dizzying, possessive joy shot through her. She wasn't just changing him. Her biology was rewriting both of them, in a perfect, symbiotic loop. He made her bigger and stronger. She made him heavier and more dependent. And now, she could literally feed him herself.
She looked down into his bewildered, adoring face and grinned, a wild, hungry flash of teeth.
“Oh, Derrick,” she whispered, pulling his head to her now-substantial chest, her mind racing with the terrifying, wonderful possibilities. “We are just getting started.”
