Blueberry Shake: Gym Mishap (Patreon)

Sophia wiped the sweat from her brow after a solid workout, her ponytail swaying as she stood in front of the gym mirror. The place was buzzing with the usual crowd—weights clanging, treadmills humming—but she felt great, ready to refuel. She'd heard about this new blueberry protein shake from a friend, supposed to be packed with antioxidants and flavor. To amp it up, she stirred in a scoop of that experimental mass builder powder she'd snagged from the supplement shelf. "Can't hurt to try," she thought, mixing it vigorously in her cup before taking a long sip through the straw. The taste was incredible—tart, sweet, bursting with berry essence.

At first, it was fine. She posed a bit in the mirror, admiring her toned figure in the gray tank top and black leggings. But then, a strange warmth spread through her core, like bubbles fizzing inside. Sophia paused, cup still in hand, as her skin tingled oddly. "What...?" she murmured, glancing down. Her arms were turning a faint blue, the color deepening rapidly, spreading like ink through water. Panic flickered in her eyes as she set the cup down, but it was too late—the mixture had reacted badly, the powder catalyzing something wild with the blueberry base.

The inflation started slow, a subtle swell in her belly that pushed against her tank top. But it built fast, juice surging through her veins, filling her up from the inside. Sophia's eyes widened in horror as her skin shifted to a deep violet hue, her breasts heaving heavier, rounding out fuller with each passing second. "Oh god, no... what's happening?" she whispered, clutching at her expanding midsection. The pressure was intense, warm and insistent, making her feel impossibly full, like she was being pumped with thick, sweet liquid that wouldn't stop.

She staggered back, her legs wobbling under the growing weight. Her belly ballooned outward, taut and heavy, forcing her to bend forward slightly as her ass and thighs joined in, swelling rounder and denser. Juice sloshed audibly inside her, the sensation both alarming and strangely overwhelming. Sophia tried to call for help, but her voice came out shaky: "H-hey... someone...?" The gym-goers nearby started to notice, whispers turning to stares.

The heaviness hit critical—her body now a massive, juice-laden orb from torso to hips, too cumbersome to stay upright. With a soft groan, Sophia toppled forward, landing on her swollen belly with a gentle bounce, her blue legs kicking feebly in the air. She lay there, helpless on the gym floor, the inflation still creeping, making her rounder by the moment. "Please... make it stop..." she whimpered, cheeks burning with embarrassment and fear.

A crowd gathered quickly—fellow gym rats, trainers, a mix of guys and girls leaning in close, their faces a blur of concern and curiosity. They murmured among themselves, some reaching out tentatively to touch her taut surface, others pulling out phones. Sophia could only stare up at them from her prone position, her body sloshing heavily, wondering how much more she could take before someone figured out how to juice her back to normal.
