Once upon a time in the ocean there was an extremely tiny nineteen year old anthro shark named Nathan, so tiny in fact that the smallest phytoplankton looked like it was three-hundred feet long from his prospective. He understood how small he was compared to normal sharks and was well educated about everything in the ocean and the world yet despite all this he loved the ocean. In fact he actually had a special relationship with the ocean that no one else did. He talked to it and he could hear the ocean talk back to him. They had fallen in love over time and had everything except for an intimate relationship, which was impossible because of his small size but that was about to change. 

One night close to the surface of the ocean Nathan saw a shooting star in the night sky. He closed his eyes and made a wish on it. The next morning Nathan woke up very hungry. The only thing was very able to do about that was to take some bites out of a tiny phytoplankton so he did. He eat more than usual and ate until he was full. A few moments he felt good pleasurable warm feeling all throughout his body as he saw his prospective sitting on phytoplankton suddenly change. His entire body had just doubled in size and now his stomach wasn't completely full anymore. He was very delighted as he swum around with excitement examining his new prospective and realizing that his wish might have actually come true. He was very proud of the fact that he had actually grown and he couldn't wait to get far far bigger. He immediately told the ocean about his wish and what had happened. She was extremely excited about it and urged him to keep eating and eat he did. After eating a decent amount he felt his whole body growing bigger again but this time he kept on eating with tremendous pride and excitement. Each bite he took was bigger than the previous one and he continued eating and growing until the entire  phytoplankton was gone. At this point was as big as the phytoplankton was and although he was still too small for a fish to see he felt like he had grown huge and loved it. The ocean loved it too. She had been watching the whole thing got extremely horny from seeing him grow. She had always thought that he was very cute and sexy but he was always far too small for them to have sex or for her to even feel him but she knew now that was about to change.

She encouraged him saying "Go on! Go on! Eat more! Grow bigger for me!". He looked around, saw another phytoplankton, started swimming towards it, and started devouring it. He grew twice as big and then moved on to next one. He continued devouring one after the other and growing larger each time until he got big enough to eat zooplankton. He had moved up to the second level of ocean's food chain. He made fun of the small size of the comparatively tiny phytoplankton all around him and then started swimming towards the nearest zooplankton. He took a big bite and then another and another. Bigger and bigger he grew until he was just as large as the zooplankton was. He swum to next one and continued eating. One after the other he ate. Each one became like a mouthful to him. He swum constantly from one to the other eating each one he encountered. Soon each one was bite size to him and then he was so big that they couldn't fill him up anymore. He grew and grew and grew and was extremely proud when saw them all disappear from his sight as he got too big to see them. He needed something bigger to eat. 

He looked around and saw a baby fish. It was a new born, freshly hatched from the egg and only one millimeter long. The ocean motivated him by saying. "Go on! Eat it! You don't expect to satisfy me at your pathetic little size do you?" He swam up and took a bite right out of it's tale and grabbed it so it couldn't swim away. It was many times his size to start with but when he was done he was now just as big as the baby fish was. It didn't take long for him to find another baby fish. Turns out a group of them had all hatched together. He ate one after the other and grew until he was one inch long. He saw a two inch fish and started swimming towards it. Couple of fish later he reached six inches long. He kept on eating all sorts of different fish and went after larger and larger ones each time. He reached the equivalent of six feet tall if he where to stand up on dry land, which was also normal size for a shark of his type. Then suddenly he felt the same good growing feeling in only one particular place on his body. He looked down at his crotch. He had a rock hard erection pointing straight up along his chest from all the excitement. It had always been average size in proportion to the rest of him but as he looked down he saw and felt his dick and balls growing bigger right before his eyes. They stopped at seven inches long. The ocean was so excited by the sight of it that she got wet. He was very proud and happy about it and rushed out to try to make it happen more. He ate a barracuda and a whole seal and grew to the equivalent of eight feet tall. He swam around looking for me food. He saw other sharks of his species some them were quit beautiful too but he wanted more. He wanted the ocean. He caught a couple of dolphins and ate them causing him to grow to the equivalent of twenty feet tall. He looked down and saw his package grow to equivalent of eight inches long. "Oh yeah!" He thought. He felt the new size of his dick and balls in his hand and then continued looking for more food.

He knew he still had to get far far bigger. He knew the ocean already had many whales and that he would have to get even bigger than them to impress her. He hated that the ocean always felt like a huge endless universe around him and was determined to change that. "I am the man here so I should be the bigger one" he thought. "I'll make her feel tiny for a change". He ate a beluga whale and then an orca whale and grew to the equivalent of fifty feet tall. He looked down as he felt himself grow to the equivalent of nine inches long. The ocean's excitement and his growing equipment got him into horny fast feeding frenzy. He ate a few sperm whales and grew to the equivalent of one-hundred feet tall. After that he was lucky enough find a whole massive herd of blue whales, which are the biggest known animals on the planet, with each adult being about one-hundred feet long. He kept eating one after the other. It made him very proud to know that was now growing bigger than the biggest the ocean had ever had. The ocean said to him. "Don't stop! Keep growing! Keep growing bigger for me! Oh please keep growing! Keep growing bigger forever and never stop! Never stop growing! Keep growing bigger forever!!!!" He devoured the last of them as they tried to swim away, growing bigger every second. He smiled down as he felt his dock and balls have biggest growth spurt ever along with the rest of his body. He swam through the ocean swallowing whales whole as he thought.  "Yes! Bigger! Bigger! BIGGER!" He swam through the ocean growing faster each second and with his dick and balls growing faster than the rest of him. He swam around the whole world over and over again growing so big that he caused giant tsunamis to wash over all the continents. He grew so much that he couldn't submerge all of himself anymore. He rose up out of the water even though his whole body was still laying down. The ocean appeared to be only a few inches deep to him and constantly appeared less. He lifted his chest up off the ocean floor a little with his arms to look down at his massive cock and balls. He enjoyed feeling them grow against the ocean floor and against his stomach. He watched with pride and amazement as they reached the equivalent of twelve inches long and then fifteen inches and then eighteen inches. His tail suddenly grew thicker and stronger but mostly longer. He felt his tail fin suddenly grow three times bigger. The length of his body and tail encircled almost the whole world. He started to be able to see the top of his own trail fin in front of him. He got so big that his body could barely fit inbetween the continents. His balls grew to be the size of oranges from his prospective and his penis kept growing bigger and stronger until it reached the equivalent of twenty-five inches long. Then suddenly he stopped growing. The ocean was like a tiny puddle beneath him with no depth to it at all. He smacked his tail down on the ocean and wiggled it across the ocean, smacked his legs and hands down on the ocean, and smacked the length of his dick up and down against the ocean sending out massive tsunamis which looked like little ripples in a puddle to him. "Am I big enough for you now little bitch?" He asked the ocean. "Yes! YEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEESS!" The ocean replied. It was nice to be a too big for her for a change he thought. "Now you know what it's like to be too small." He said and then they proceeded to have the greatest sex ever.
