The sun blazed over the sandy beach as Nagatoro and her friends laughed and ran along the shoreline. Gamo had just tossed the beach ball high into the air when — pop! — it burst spectacularly, leaving everyone staring at the deflated rubber in shock.

“Aw, come on!” Gamo groaned, holding the ruined ball. But instead of fixing it, a mischievous grin crossed her face. In a wild spur-of-the-moment idea, she grabbed a nearby air tank and tube. “Well… why not?” she muttered, shoving the tube into Nagatoro’s inflatable device — or so she thought.

Nagatoro’s eyes widened in horror. “Hey! What are you doing?!” she yelled, struggling as the tube started pumping air rapidly. Her favorite swimsuit strained and ripped at the seams, seams stretching impossibly as her body expanded like a massive balloon. Her limbs flailed, hair bouncing wildly, as she bounced up and down with each puff of air.

Her friends scrambled, trying to grab the tube, but Gamo had a mischievous hold on it. Nagatoro rolled and tumbled across the sand, her inflated form wobbling uncontrollably. “This isn’t funny!” she shouted, but even her indignation sounded funny to everyone watching.

You, standing nearby, rushed over just in time to grab the tube and stop the inflation, steadying her before she could roll into the waves like a giant, puffy beach ball. Nagatoro huffed, adjusting the ruined swimsuit while glaring at Gamo. Despite the chaos, you noticed a tiny smirk at the corner of her lips — the sheer absurdity of the situation making it impossible to stay mad for long.

“Next time,” she muttered, still slightly bouncing, “I’m picking the games.”
