Anya stretched lazily in bed, feeling a dull heaviness in her stomach. She brushed it off as a minor discomfort from last night's dinner. After breakfast, though, she noticed her belly seemed rounder, with a slight but odd firmness.

Anya stood in the kitchen, her eyes fixed on her reflection in the glass door. Her stomach, now unmistakably protruding, seemed out of place on her slender frame. She frowned, wondering if stress or a late-night snack was to blame.

As lunchtime arrived, Anya could no longer ignore the bizarre expansion. Her belly had grown to the size of a watermelon, creating a tension that felt like an internal balloon stretching her skin. She called her friend Katya, her voice tinged with anxiety.

Katya arrived, her disbelief evident as she prodded Anya's round belly. "Are you sure you're not pregnant?" she joked, but Anya's nervous laugh didn't erase her worry. "I'd be the first to know about it!" she replied, eyes wide.

The roundness intensified, and Anya felt like a balloon ready to burst. Her skin shimmered with odd reflections. Katya, desperate, suggested an absurd solution: "Maybe we should pop it?" But before they could decide, a soft crack filled the air.

Anya's stomach erupted with a loud "PFFF!", releasing a sparkling cloud that enveloped the room. She landed with a thud, Katya blinking through the colorful dust. "Well... At least you're back to your normal shape," she quipped. Anya sat stunned, her deflated belly a mystery, as the sweet scent of caramel hung in the air without explanation.
