Something felt odd. As Rachel soaped and rinsed herself, it seemed like something was pressing down on her. The cascade of water itself was like a downward force that made it harder and harder to stand up. She wiped the soap and water from her eyes and looked around. Everything seemed normal. The water wasn't coming out faster than usual. It was when she shifted her weight to turn around that she finally thought to look down.
She screamed at the sight of her massive belly. It was jutting out at an impossible size, looking like she had just gained over thirty pounds. She could barely see her toes beyond its rotund girth. And it kept getting bigger. Her breasts appeared to be doing the same. They lost their usual pertness and began to droop like water balloons.
The water! That was it! Her body was taking on water! She turned quickly to grab the nozzle, but being unused to the drag of her stomach she lost her balance and plopped down on her very well-cushioned ass. Water pounded in her face as she blindly reached for the handle. At last, she found it and shut off the water, but it was far too late.
Rachel sat in the bathtub, running her slightly chubby hands over her body, which was now a glorified water repository. The sheer weight of all the gallons of water pinned her to the tub like a beached whale. After a few minutes of desperately trying to stand up, she broke down in a fit of very watery tears.
