Raikou's drinking problem

In the dimly lit hall of a traditional Japanese inn, Shuten Douji, with her cheeks flushed from the sake she had been drinking, stumbled towards Raikou. The air was thick with the scent of alcohol and the warm haze of inebriation. Shuten, giggling to herself, clutched her oversized sake flask tightly, her eyes gleaming with mischief.

"Raikou, you have to try this," Shuten slurred, her words barely coherent. She approached Raikou, who was resting on a futon, her guard lowered in the presence of her friend. Raikou, ever the dutiful warrior, eyed the flask warily but trusted Shuten enough to take a sip.

However, Shuten had other plans. With a playful glint in her eye, she tipped the flask, pouring a copious amount of the magical sake into Raikou's mouth. Before Raikou could react, she felt a strange sensation spreading through her body. The magical sake started to take effect immediately, causing her body to swell and inflate uncontrollably.

Raikou's eyes widened in shock as her limbs puffed up, her belly expanding into a taut, rounded shape. Her armor strained and eventually snapped, unable to contain the growing mass. Her once slender form was now a massive, water balloon-like figure, her skin smooth and glistening in the dim light.

Shuten, in her drunken stupor, found this immensely amusing. She clambered on top of the inflated Raikou, giggling and poking at her ballooned form. "Look at you, Raikou! You're just a big, bouncy balloon now!" she laughed, her voice echoing through the hall.

Raikou, still conscious but utterly helpless, could only blush and sigh, accepting her fate for the moment. She knew that once the effects of the sake wore off, she would return to normal. But for now, she was at the mercy of Shuten's drunken antics.
