Reincarnated As A Dungeon Core; Now I'll Build My Monster Girl Harem!

Leo was a 24-year-old virgin gamer—obsessed with hentai dungeon builders, endless grind sessions, and monster girl waifus he could only dream of touching. One fateful night, Truck-kun finally grants his ultimate fantasy... by smashing him into oblivion. He awakens not in heaven, but as a glowing Dungeon Core in Elyria—a brutal, post-apocalyptic fantasy world ravaged by ancient gods and crawling with desperate adventurers. No body, no hands... until he discovers his unique power: summoning an army of insatiable monster girls—succubi with dripping wet tails, jiggling slime girls begging to envelop his cock, dark elf slaves in heat, lamias with coiling tentacles, and more—who evolve only through thick, hot "mana injections" straight from their Master's throbbing shaft. Virgin no more, Leo manifests a perfect avatar body built for endless breeding. Every deep thrust, every overflowing creampie, every public orgy in his expanding dungeon floods him with power. He levels up by fucking his loyal harem senseless—tentacle gangbangs in breeding chambers, slime bukkake rituals, succubi riding him while draining captured adventurers dry. Soon, brave (and stunningly busty) female adventurers flood his traps, only to end up stripped naked, minds broken, pussies addicted—converted into eager new monster girl wives begging to be bred again and again. From a weak core in a forgotten cave, Leo builds a vast underground empire of endless ecstasy: floors dedicated to non-stop orgies, nurseries swelling with his half-monster offspring, and throne rooms where his harem worships his cock in massive, moaning group rituals. In this world beyond the timescape, power isn't taken—it's pumped, thrust, and flooded into willing, writhing bodies. One virgin gamer. Infinite horny monster girls. Zero mercy. Get ready to plunge deep into the ultimate uncensored isekai harem fantasy—where every level-up ends in explosive, womb-filling climax. --- Support this story by adding it to your collection, giving Power Stones, and Golden Tickets!
