Story:

After a busy year of studying, Aoi Asahina was excited to spend her summer working at the local pool. She’d been hired as a lifeguard so she could enjoy the sunny months doing what she does best - swimming. But when she arrived at the pool, her body began to change. Cat ears grew on her head as a tail sprang from her backside - and her breasts and butt began to swell with alarming speed. Had this been brought on by the donuts she ate this morning? Had she somehow invoked a curse on herself by wishing to spend the “whole summer in the water”?

Regardless of the cause, and in spite of her protests interspersed with moans and “nyas,” she soon found herself lying prone on the ground with a massively inflated body, unable to move or speak. She could see her swollen breasts in front of her, but could plainly feel her butt had swollen to a much larger size. “Is this some kind of allergic reaction?” she thought, panicking, her eyes darting back and forth. She hoped desperately that someone had seen her fall, not realizing that her body had taken on a completely new form.

After some minutes, some members of the pool staff found her. Overwhelmed with relief, she thought she’d been saved. “They’ll bring me to the infirmary or something, they’ll have a way to fix this.” But instead of the worried and sympathetic words she expected, an argument broke out instead. 

“Is that the new pooltoy? Holy shit, it looks more like a blowup doll.” 

“Nah, it’s got cute kitty ears. Just put it in the pool, no one will care.”

“Yes, it’s got kitty ears and a huge ass. Don’t you think parents will complain?”

“I’m not a pooltoy, nya! I’m the new employee!” Hina thought the words as hard as she could but the argument continued. After a few minutes, both employees shrugged and she was unceremoniously lifted up and thrown into the pool, completely disorienting her. The water felt nice on her skin, but Hina could hardly focus on that in her current predicament.

As she bobbed up and down in the warm water with no way to move, she tried any number of ways to draw attention to herself, but no one seemed to realize who she was... or that she was even a person. She occasionally felt a glimmer of hope when she managed to establish eye contact with another person in the pool, but it never led to anything. One time she caught the eye of a young man, who simply said “Ha, look at that silly expression. The cat has no idea her big butt’s out for everyone to see.” “I do know! I do know, nya! And it’s not that big!” she said, or tried to, but all she did was bob up and down a small wave, letting the sunlight reflect off her “not so big” butt. The situation had been too confusing to even consider this at first, but her face started to feel hot from embarrassment. Her body always drew some glances, but she felt very uneasy when people would actually talk about it - which they now did constantly with her large breasts and enormous butt on display. To make matters worse, the rest of the pool was populated with donut-shaped floaties, taunting her. Her favorite food was constantly in her line of sight, but she could never have a taste - not that the plastic floaties would’ve tasted good, anyway.

A few days passed like this, and she soon realized she had drawn some attention - albeit not in the way she had hoped. People had taken note of the curvaceous looking pooltoy and rumors began to spread. Visitors to the pool began to refer to her as “the fat ass,” “the sex doll” and the “blow-up doll” much like her “colleague” had called her. More and more people came to visit the pool, and the staff was quick to capitalize on their new attraction. They called her the ‘Lucky Cat’ in a bid to remove the less favorable names people had thought of and invented an entire story around her. “She’s a very dumb and greedy cat - that’s why her butt is so big - and she’s looking for fish in the pool, not realizing there are only people in there. It’s good luck to slap or squeeze her butt as hard as you can and tell her ‘there are no fish here, you silly cat!’”

With the “legend” in place, Hina’s “work” at the pool became much worse. Every day, dozens if not hundreds of people swam up to her to slap or grab her butt with ferocious energy, all while informing her of the fact that there were no fish in the pool. Pooltoy though she may be, she felt the slaps and each sent a wave of pain and pleasure through her whole body that she could not express. The frustration got worse and worse with each day.

Slap! “There are no fish here, you silly cat!”

“Nyaaa! I know! It’s a swimming pool!”

Slap! “There are no fish here, you silly cat!”

“Nyaaa…! That hurts! And I know that already, you’re like the twentieth person today!”

Slap! “There are no fish here, fatass!”

“N-nyaaa… I know there aren’t any-- wait, what did you call me?”

At this rate, it was going to be a very, very long summer for Hina, The Ultimate Pooltoy. But at least it would be over after the summer… right?
