Some Kind of Pool

You swear you could hear some mischievous giggling as you duck into the local community centre, taking a moment to gaze around the darkened streets behind you. Summer was ridiculously hot and it didn't help that the city closed down this entire place for some mysterious reason. So, you devised a simple plan: Sneak into the centre at night and enjoy having the pool all to yourself. What could go wrong?

As you proceed into the dressing room, you hear that giggling again echoing from down the hallway to some lonesome corner of the building. It was strange, sure, but you think it sounds more like some kind of issue with the ventilation than anything else. Besides, who would stalk around a place like this at night? 

You push all sorts of wild and imaginative thoughts to the back of your mind once you step out of the dressing room and out to the pool proper; you had this place all to yourself for as long as you'd like, why let a couple of strange noises ruin this?

Finally, you step into the cool, inviting water, watching as ripples distort the reflection of a full and particularly pale Moon. It felt as if all of your troubles were melting away as the water washes over you, lapping up at your chest. You close your eyes and inhale deeply, taking in the tranquility. You hardly notice as you drift into a gentle sleep.

Suddenly, you're jolted awake as you inhale a mouthful of water. Did you just fall asleep? You struggle to remain afloat as you flail your arms desperately, waves of water crashing against your chin and over your face. A soft giggle emits from the side of the pool, but you struggle to make out anyone in the darkness. Finally, as you clumsily paddle towards the pool stairs, you can't help but notice your arm was bloated to the point of enormity. You shriek once you glance down, finding your vision blocked by a massive pair of shaking tits snugly bound in a bikini top. 

Worse yet was the fact that they were still getting bigger before your very eyes. A curious, albeit panicked glance around your body confirmed the awful truth: Somehow, you were no longer yourself whatsoever; you were a woman, and a heavyset one at that. The sight of your gigantic ass left your mouth agape. You gasp for breath at the monumental effort required to walk back to the shallow end of the pool, your enormous thighs grinding against one another as if fighting for space. The way your belly swayed along with its impeding weight forced you to waddle in an exaggerated and exhausting fashion. It felt like you were waddling through syrup. 

You heave yourself up onto the pool stairs, the weight of your belly anchoring you to the floor. The pressure against your stomach leaves you feeling sick. You lean forward as you're forced to release a loud, raunchy belch. The unseemly noise echoes off of the walls. The giggling returns, but it's louder and more uproarious than before. In fact, it sounds like your unseen assailant was now laughing at you. 

Tears well up in your eyes as you fight to pull yourself to your feet. You move to run towards the dressing room but your excessive size slows you to a crawl, leaving you breathless as you ponderously make your escape. Somehow along the way, you manage to grab your clothes as you take off from the community centre, making your way home as fast as your new body would allow you to.

Ever since that day, you found yourself reduced to a hopeless shut-in, far too humiliated by your new, embarrassing state to go outside. At the very least you were able to keep yourself occupied, whether it was stuffing your face, indulging in your hobbies, or toying with your new, sensitive slit. A few weeks later, you decide to make the trip again, desperately hoping that you would somehow be restored but other than plentiful giggling and an invisible force pinching your fat ass, nothing happened at all, forcing you to adjust to your new life.
