Princess Lyra was used to getting her way. Her cheeks glowed with a spoiled flush, her glossy hair spilling over her shoulders in perfect waves. She pouted, flipping pages, bored and angry that her uncle had left her in charge for two whole weeks. The castle seemed quieter, but she relished the power, her every whim fulfilled. Yet, the spellbook’s mysterious symbols tempted her curiosity, promising excitement beyond her usual indulgences.

Lyra muttered incantations, her voice sharp with frustration. She traced runes with manicured fingers, hoping for a spell to make herself even more beautiful. Instead, a strange tingling spread through her body. Her belly began to swell, the sensation oddly pleasant. Her reflection in the gilded mirror showed her stomach ballooning and her hips expanding, her face flushing with both shock and delight. "Oh! I look... ridiculous, but it feels so nice."

Lyra couldn’t help giggling at her reflection, despite knowing she’d made a mess of things. Every morning, she tried a new spell to shrink herself, but instead, her belly ballooned larger and her butt bloated even more. Soon, she was little more than a rolling ball, her arms and legs barely visible. She rolled across her silken rugs, her tiny hands and feet sticking out, enjoying the odd sensation. "Well, if I can't fix it, at least I look fabulous in these bikinis."

Lyra knew trouble was coming. Her uncle would return soon, and she’d never be able to hide her inflated form. She squeaked and blushed, feeling both panic and pleasure as she rolled from room to room. Eventually, a stern voice echoed through the halls, and she realized she’d been caught. Uncle Magnus appeared, robes swirling, his eyes wide in disbelief. "Lyra! What in the world have you done to yourself?" "It’s… not what it looks like!" she protested, but Magnus was already searching for a reversal spell.

Lyra refused to be changed back, protesting that she liked her new shape. She rolled away, splashing happily into the pool, only to be found again by Magnus, who tried spell after spell. Each attempt made her inflate even larger, her body swelling to enormous proportions. "Stop! I don’t want to go back!" she insisted, her voice muffled by her roundness. Magnus shook his head, but the magic was out of control, her body growing bigger and rounder with every spell.

Lyra’s joy and excitement became overwhelming as she grew, her body filling more of the castle than she ever imagined. The sensation was intoxicating, but soon she was so huge, she could hardly move. Magnus, desperate, tried one last spell, but it only made her grow faster. The garden shook, petals flying as Lyra reached her limit. "This is… amazing!" she squealed, just before everything went out of control, and she felt herself stretch to the brink of popping.
