The quiet hum of the train is completely overshadowed by the grotesque symphony happening in the seat next to you. Kiba Haida, the woman who had been a picture of quiet dignity moments before, is now slumped in her seat, her entire frame trembling with exertion. Her hands are pressed deep into the sides of a stomach that has swollen to an impossible size, a churning, heaving sphere of flesh straining against the fabric of her cream-colored blouse. The distinct outline of a man—his kicking legs, his balled fists—is gruesomely visible, fighting a futile battle from within the muscular prison. A low, pained groan escapes her clenched teeth, a sound halfway between agony and ecstasy. "Aghhh... Mhmmph..." she whispers to herself, her eyes squeezed shut, a single tear of effort tracing a path through her blue eyeshadow. "Relax... Relax..."

The struggle inside her only intensifies, and the sounds grow louder—a deep, wet "GWOORGLL" that vibrates through the seat. Ten minutes pass in a blur of horrific churning. As the form inside her begins to lose its definition, melting into a thick, sloshing mass, Kiba's groans deepen, her back arching violently. Her hands leave her gut and clutch at her own swollen, sagging breasts, kneading them as a wave of overwhelming pleasure washes over her. "SAHHHHHHHH..." she cries out, a raw, unrestrained sound of pure, orgasmic release, her head thrown back against the window. The churning inside her reaches a fever pitch—"GLOORP! GWOORRGGLL!"—before finally, mercifully, subsiding.

Panting, she slumps forward, a bead of sweat on her brow. The once-taut sphere of her belly softens, settling into a heavy, overhanging paunch of newly acquired flesh that spills over the waistband of her now-ripped pants. The seams around her hips and massive ass have split, unable to contain the sudden padding. The train's automated voice announces the next station. Kiba lets out a deep, shuddering sigh of contentment, followed by a long, resonant, and utterly shameless belch that fills the small space. "AHHWOOORPP!..." She gives her new, soft and slightly obese belly a gentle, satisfied pat. "Oh, here's my stop," she murmurs, straightening herself up. "I better get going now." As the train doors slide open, she stands, her new weight settling into her hips, and turns to leave, her weary eyes catching yours for a single, knowing moment before she steps toward the exit.
