"I'm sorry I'm late, Dr. Stanczyk!" Katelyn yelled as she sprinted into the laboratory. "I couldn't find my key to the apartment, and then I didn't get off at the right subway station and-"

"Don't worry about it, Katelyn." Dr. Stanczyk said humbly. "I know how busy you have been lately. We are just about to head into the field. Go ahead and grab your gear."

"It won't happen again, Doctor!" Katelyn said as she placed her backpack on a lab table.

"Oh, I'm sure it will." the doctor laughed.

Dependently late, Katelyn scrambled to get on her scuba gear. Today she and the doctor were boating out to the barrier reef just a few miles off the coast of New Jersey. Dr. Stanczyk and Katelyn's mother had been friends in college, which allowed Katelyn to work as a summertime assistant to Dr. Stanczyk. She wanted to be a marine biologist, just like him. Working as his assistant allowed her to have hands-on experience as one.

"I'll be out in the car, Katelyn!" the doctor said as he shut the lab door.

Katelyn hurried up behind him and shut the lab door. The drove for a few miles out of town until they reached the beach where the doctor's seaside lab was located. Grabbing only a few pieces of equipment, they entered the boat and began their journey.

"I received news that a passing cargo ship lost a box of material just outside the reef last night. I want to see if we can recover anything and how it has affected the marine life there." Dr. Stanczyk explained.

Reaching the reef, Katelyn could see some debris floating on the top of the water. She put on her flippers and stood up, ready to jump into the water. She tied her platinum blonde hair back into ponytail and dove in. Her graceful figure cut smoothly into the calm waters. With her oxygen mask on, she swam over towards the reef. There wasn't as many fish as there used to be. This confused Katelyn until she saw what lay by the reef.

Barrell upon barrell of nuclear waste lay spewed amongst the coral reef. Looking up, Katelyn could see the dead bodies of different fish species floating at the top of the water. The bright yellow barrels were scattered all over the ocean floor. Katelyn was about to go tell Dr. Stanczyk what she saw, when she swam too close to the reef. She sliced her arm on a particularly sharp section of coral. Her blood dyed the water around her a light red color as she grabbed her arm in pain. She swam back to the surface and informed the doctor of her discovery.

"Toxic waste?! Katelyn, get out of the water!" Dr. Stanczyk ordered. "We need to get out of here!"

Katelyn climbed back into the boat clutching her injury. She didn't want to tell the doctor in fear that he'd overreact about it. She always seemed to mess something up when they did field work. They arrived back at the lab and Katelyn bandaged it up quickly, then put on her hoodie, disguising the cut. After a few hours of documenting the accident, Katelyn grabbed her backpack and left.

"Good night, Doc!" she said in a hurry. "I'll see you next weekend!"

Katelyn entered her messy apartment and locked the door. Clothes were scattered all over the floor, the TV was still turned on, and a stack of dishes were left by the sink. Katelyn would clean it, but it'd only get messy again. She just didn't have the time. She walked into the bathroom and started the hot water for her bath. She took off her bright blue hoodie and dropped it to the floor. She unbuttoned her jean shorts and slid them down her smooth, curvaceous legs. Unhooking her bra and throwing it the floor, she revealed her quite large breasts. Finally taking off her panties, she stepped into the steamy, warm water.

Katelyn let out a moan of comfort as she slid slowly into the warm bath water. She looked at her arm to re-examine her cut when she noticed...it wasn't there. This took Katelyn by surprise. Wasn't there a very large slice in her arm just a few hours ago? There is no way it could have healed that fast! She was very worried about what may have happened to her after being exposed to the radioactive water in that area. She hadn't known what she was getting herself into!

She hadn't noticed it at first, but as she was relaxing in the water, Katelyn's thighs slowly started to swell up. Katelyn began to feel a little uncomfortable inside the tub, and she adjusted herself. To her surprise, her butt seemed a little bigger than she remembered. She reached down and gave it a gentle squeeze. It definitely felt a lot wider than it was this morning. All of a sudden, she felt very warm inside. It was a good, soothing feeling. She looked down at herself and her eyes widened. Her thighs had at least doubled in size. They were squishing against the sides of the bathtub. Her hourglass figure became even more exaggerated when Katelyn's already large breasts began to slowly fill up like two big balloons.

Katelyn reached up to grab them, squishing them to really feel what may be happening. Her breasts swelled up larger and larger, as her butt got rounder and bigger by the second. Katelyn didn't even notice, but the level of the water in the bathtub got lower and lower as this was happening. She quickly stood up and looked at herself. Her breasts had swelled to this size of two beach balls and her hips were quite huge. Even her belly had blown up a little bit, making Katelyn look very bloated. She felt heavier and very warm. She looked at herself in the mirror and gasped at her swollen figure. Looking back at the bathtub, she noticed that only about a foot of water was left inside. Then it hit her...

She is absorbing the water.

Katelyn's smooth, bloated body was dripping with the warm bathtub water. She jiggled her breasts and could hear the sloshing of the liquid inside. She shook her hips and watched in the mirror as her ass jiggled back in forth. The steamy hot water had filled her body, and there was still more in the bathtub. She didn't quite understand how this was possible. Willing to experiment some more, she stepped her foot back in the tub, and felt the water soak into her body. Her breasts filled up faster and faster, become very very large, and her belly bloated outward, making her look quite pregnant. Soon enough, there was no water left in the bathtub, and Katelyn looked enormous. She panicked and called the doctor, explaining everything. The radioactive material. The cut on her arm. Her inflating figure. The water in the bathtub soaking into her body. Dr. Stanczyk requested that she come as quickly as she can.

Katelyn slammed the phone back down on the receiver and tried to put on her sweatshirt, but it would not fit over her enormous breasts. Even her panties started to rip as she pulled them up her giant thighs. Katelyn ran all around her apartment, swollen and completely naked, looking for something to wear. She finally found a hoodie large enough that could barely contain her massive figure. It was such a tight fit, Katelyn was had a hard time breathing. Her massive boobs stretched the hoodie so tightly, it would rip at any second. She also put on a pair of stretchy sweatpants that could contain her enormous hips. She simply had to go without the underwear. She grabbed her purse and left out the front door.

Leaving her apartment, Katelyn felt very exposed and very embarrassed of her giant figure. Luckily, nobody was inside the apartment complex at this time of night, but she was sure to encounter somebody on the streets. Walking briskly past an alleyway on the sidewalk, a voice yelled out from the darkness.

"Listen young lady," a masked figure said as he stepped towards her. "I don't want any trouble. Just hand over your purse."

Katelyn turned to look at the masked man, and he almost dropped his knife at the sight of her.

"Holy shit, girl!" he yelled. "What did you eat! You're huge!"

Katelyn ignored this insulting comment and spotted the knife in his hand. She backed up slowly, ready to bolt as fast as she could. She didn't even know how fast she could run in this given state.

"Hey pal," Katelyn said, standing up for herself. "I don't know who you are, but I don't have time for you. So just go on home, and you won't regret messing with me."

A little nervous about taking a stand in this form, Katelyn stood her ground. The masked figure approached her rapidly with his knife drawn. And as Katelyn raised her fist to fend off the crook...

WOOSH!

A jet stream of water blasted forward from Katelyn's arm. It smacked right into the masked figure's face, blasting him into the air and falling into a dumpster along side the alley. Katelyn slowly lowered her arm and looked at her hand. It was dripping with water, and the entire alleyway was soaked. The crook climbed out of the dumpster and ran for his life, stumbling along the way in his dripping wet clothes.

Katelyn also felt much lighter. She looked down and noticed that her breasts had significantly shrunken in size, and her hips were no longer swollen up. Her sweatpants felt very loose now and her sweatshirt fit comfortably. Then, it all came to her. Katelyn was gifted with some kind of power from that radioactive injury. She can absorb, hold, and expel water from her body. Just like a sponge! Katelyn couldn't help but smile at this spectacular discovery.

She climbed onto the next subway and made her way to Dr. Stanczyk to inform him of this incredible discovery.
