I'm a merchant seaman. The ship I was on got destroyed by a hurricane, and I managed to get in a lifeboat and secure myself to it. The raging winds buffeted me and the lifeboat badly, and I fell unconscious.
When I awoke, the lifeboat had been tossed a hundred feet up a beach, onto what had to be an island -- we weren't within a thousand miles of any continents when the hurricane hit. I unstrapped myself, heaved myself to my feet, and headed into a patch of trees. I was suddenly seized and lifted into the air.
"What have we here?" said a feminine voice. "A tiny morsel?"
I looked around and saw what had seized me -- a naked giantess, who was about six or seven times bigger in every direction than a normal human. If she had been human-sized, her body shape would have been "busty BBW". She had long, tangled blonde hair.
"Nope, just a lost sailor whose ship got destroyed."
She laughed. "You have spirit." Then she sliced off my clothes with her sharp fingernails. "I am naked, so you will be also."
That seemed fair. "I told you how I got here. What's your story?"
"About six months ago, I was being transported in a prison plane between two continents, and I overpowered my guards, knocked out the pilots, seized a parachute, and sent the plane spiraling downwards into the cumulonimbus clouds as I jumped out and activated the parachute. The storm-force winds carried me here. I went into a large cave, drank a flask I found that contained liquid because I was thirsty, and ended up like you see me now. My clothes did not expand with my flesh, and I could feel my bones thickening to accommodate my extra mass."
"It must have been a very large cave for you to get back out of it at that size."
"Indeed it is. I will show it to you some day."
She strode about fifty yards to the edge of the island, where a large "X" had been carved in the ground. "If you need to perform a biological function, wade out into the ocean where the X is, and do it there. The current at the spot carries things directly away from the island."
She set me down, and we both did so. She could wade out farther than I could, but that detail didn't matter. We walked back onto the island and towards the clump of trees: in it there was a clearing, where we both sat down. We talked for a while, learning more about each other: at age 24, she had been framed for a crime (and forcibly sterilized, with all the eggs stripped out of her body) because she had knowledge that would embarrass an oligarch who was close to the country's leader. I had grown up in a family of merchant seamen, so that was my career path, which I began at age 22 once I passed the required exams and got the certificates. As the sun started to set, she picked up what looked like a parachute that had slits in it -- presumably the one she wore when she arrived -- and walked about 200 yards in a different direction, to a beach. She walked out into the ocean a few strides. A school of fish, hundreds of thousands of them at least (probably more like a few million), was there: she slid the parachute under them and lifted upwards. The water poured through the slits, and about 200 fish were trapped in the fabric. We walked back to the clearing, and she said, "Take one."
I took two, in fact, and followed her example by eating them raw. She ate the rest, swallowing them whole. She effortlessly tossed the two fish skeletons I left behind into the ocean. "This is what I live on. They school at around sunrise and sunset: two meals per day." We walked about 50 yards to where she had arranged some rocks into a very large bowl-like shape. "This is the tropics: it rains enough that there's always enough water in here to drink." We had to use our hands to cup the water, but that was not an issue. Sure enough, it started raining as we walked back to the clearing.
As she lay down on what appeared to be rocks covered with sand, she observed that my cock was hard. "Well, you are gorgeous, and you are naked," I said.
"I'm also much bigger in every direction than a normal woman, in case you hadn't noticed," she replied.
I climbed up onto her and positioned myself next to her lips. "That doesn't matter to me." I kissed the corner of her mouth.
"In any case, it's time to rest," she said. "I am glad you find me attractive. All women like being shown that they're beautiful."
She closed her eyes, and I crawled down her body and lay my whole frame between her soft, plump breasts. I closed my own eyes.
