Fertilia, Land of Boundless Fertility

As you arrived home after a long and stressful day of looking at nothing but a screen as well as taking calls from some of the most braindead people on the planet, you stepped through the door of your apartment without looking, expecting to find the familiar clop of your office shoes against the hardwood floor. Instead, your foot sinks slightly and as you look down you realize your standing in dirt. You look up and suddenly are surrounded by several biomes that flawlessly intersect. From sprawling Tundras and Deserts, to Forests with as many trees as there were people on Earth, to even a vast ocean, it's waves gently lapping at the nearby beach. You look back, confused as to how you ended up here and trying to go back. The door you entered through is gone, however. Leaving you with the choice of which biome you visit first. When you look North, you see a dense forest of trees with large trunks and a variety of small insects and mammals skittering along the dirt, even some fantasy creatures milling about. They are all unlike anything you have seen before however. The trees split their bark in an inviting fashion, revealing fleshy, pulsating insides the color of wood. The small mammals and fantasy creatures such as squirrels and Nagas possess large and dripping wet vaginas that seem to ache for some kind lof release they can never find. Even the blooming flowers are bigger than they should reasonably be, possessing hidden slits that flit open in invitation at the center. To the East, you see a massive desert, it's dunes piled as high as four-story buildings with several oasises dotting the landscape where camels, ostriches, kangaroos, and even Harpies and anthropomorphic Lioness' gather to get their share of fresh water, but all of them possess a unique slit that seems strangely just large enough to accommodate a variety of sizes of human anatomy. To the West, lies a sprawling Tundra. It's grasses frozen over with a light layer of ice over top. The vegetation is sparse here, but white foxes, polar bears, ice giants and large dragons covered in protective layers of ice dot the land, making it feel far from dead despite the minimal amount of plant life. To the south, is an ocean that seems to stretch on forever, it's waves gently washing up the sand of the nearby beach. Fish pop out of the shallow water as if to greet you while Mermaids sit on the rocks of the shallow tide, their fingers running through their eternally wet and long hair, all of them possessing a slit or open and inviting hole that seems to try and pull you towards them. Everything that you could ever think of that could potentially hold life seems to have evolved just to breed with humans. Fantasy creatures, anthropomorphic animals, feral animals, even the plant life in this world seems to have a hole built to accommodate you. Stepping into any of the four biomes, you feel a rush of energy flowing through you, your body acclimating nicely to each environment, allowing you to breathe underwater and withstand the extreme heat of the desert or the icy cold of the tundra. The world is open to you now, you. It seems as though you will be protected from disease, exhaustion, and death wherever you go. The only question is... where will you go? To northern Forests to frolic among the vast vegetation and forest life? To the east, to slake the thirst of the beings who call the Desert home? To the west, to warm the hearts (and wombs) of the tundra inhabitants? Or will you go south, and embrace the untouched world of water that could not be thoroughly explored by humans before?
