Full Gut

Amber had always wanted to gain weight. No matter how much she ate, her body refused to change. Her stomach stayed flat, her limbs slender, and her frame stubbornly thin. It wasn’t for lack of trying—she devoured snacks, downed sodas, and stuffed herself at every meal, but her metabolism burned it all away before it could stick.

Tonight, though, things would be different.

Her boyfriend, Jake, grinned as he placed a small bottle in her hands. “This is it,” he said. “A pill that turns everything you eat into fat for the next 24 hours. Your genes will take care of the rest.”

Amber’s heart pounded with excitement. She popped the pill into her mouth and swallowed. He handed her another gift—a black shirt that read Stuffed Tummy, Full Gut in bold white letters, a freebie from the pill manufacturer. Alongside it, he revealed a mountain of food: french fries, bags of chips, chiken nuggies , sodas, and an assortment of desserts.

“I’ll be back with pizza,” he said, heading out the door.

Amber didn’t wait. She dove in, shoveling food into her mouth, gulping down soda between bites. At first, it felt normal—like any other binge—but soon, she felt a strange pressure in her belly. She glanced down. Her stomach, once flat, was rounding out, stretching her shirt tight. A thrill shot through her. It was working!

She kept eating. The growth sped up. Her belly pushed outward, inching past her lap. Her thighs thickened, her hips widened, and her chest swelled like rising dough. Her pants dug into her, forcing her to pull them down. Her skin tingled as her body softened, rounding in every direction. Her belly, once barely noticeable, now jutted out like an overstuffed beach ball.

Fueled by excitement, she picked up speed, devouring food with reckless abandon. Sauce dripped onto her belly, crumbs stuck to her cheeks. Her thighs pressed together, forcing her legs apart. Her arms thickened slightly, the sleeves of her shirt struggling to contain her growing upper body. Her breasts, once modest, ballooned into twin watermelons, the shirt riding up until it barely functioned as a bra.

She belched, rubbing her swollen gut. It stretched forward like an overfilled bean bag, heavy and warm. Her stomach rumbled, demanding more.

By the time Jake returned, carrying a stack of pizzas, Amber was unrecognizable. Her belly sprawled before her, massive enough to fit four grown people inside. It rested on the floor, spreading out like an overripe pumpkin. Her arms, now plush and soft, barely reached past her chest, which had grown so large that her shirt had entirely given up, acting more as a bra than anything else. Her thighs were thick and her hips had widened. Obviously she had a body type more favoring her upper body than her lower. Wrappers and empty containers littered the floor around her.

Jake stopped in the doorway, eyes wide. “Wow,” he said. “You really went for it.”

Amber grinned, licking sauce off her lips. “You’re back.” As she spoke, a glob of food slid down her chin, disappearing into the deep valley of her cleavage already pooled with sauce and food.

Jake smirked, dropping the pizzas beside her. “The van’s packed full. It’ll take a while to offload.”

Amber beamed, reaching for a slice. She had no idea how big she’d get by the time the 24 hours were up, but she would enjoy every bit of it.
