Imagine waking up not in heaven, but in a world where pleasure itself is a forgotten concept. In *FREE USE in Primitive World*, a man finds himself reborn into a savage, tribal era where survival is the only instinct. But this new world is missing something crucial: desire. Sex is a cold, joyless act until his arrival. He awakens with a chaotic, forbidden power – the ability to command absolute sexual surrender. Armed with this "gift," he embarks on a crusade to introduce pleasure to this innocent, if primal, world. No woman is off-limits as he sets out to corrupt this world, one conquest at a time. But this world is far more than it seems. Our protagonist soon discovers his new home is merely a tiny island in a vast, sprawling expanse teeming with prehistoric beasts, primordial elves, elemental lords, and mythical creatures ripped straight from nightmares. Creation itself is still in flux, and the gods are raw, terrifying forces to be survived, not worshipped. This isn't just a land of untouched healers and fierce huntresses; it's a battleground for survival where the very weather can kill you. How will our MC navigate this dangerous landscape, and can he truly achieve his dream of building a massive harem across countless races? Dive into this epic fantasy disguised as a smut novel, where civilization-building and divine wars collide with the most primal desires.
