The series follows Takeru, a hardcore eroge addict who's isekai'd into a fantasy world where his encyclopedic knowledge of fucking in hentai games is the ultimate superpower. His grand adventure is a relentless series of sexual conquests where he solves every problem by fucking it into submission. Takeru first encounters a desperate elf princess, plowing her tight, virgin cunt until she's a screaming, cum-drenched mess, her political troubles forgotten in a haze of raw pleasure. Next, he tames a wild beast girl, mounting her from behind and pounding her pussy until her primal instincts are replaced with a deep-seated lust for his cock. His journey culminates with the Demon Lord herself, a powerful matron whom he brutally hate-fucks, breaking her will with his relentless thrusts and turning her into another devoted addition to his ever-growing fuck-harem. Each episode is a new conquest, showcasing Takeru's ability to use his dick to dominate any woman, solve any crisis, and build a kingdom on the foundation of their mind-shattering orgasms.
