Kota Sakamoto—a socially awkward otaku and devoted hentai game enthusiast—finds himself transported into the explicit world of Carnal Labyrinth EX, the adult strategy game he'd mastered in secret. His eight attractive classmates and their intimidating female teacher are pulled into this nightmare alongside him. The problem: they despise him. Making matters worse, the dungeon functions identically to the game—each chamber presents obscene, life-or-death challenges where succumbing to pleasure means annihilation through overwhelming stimulation, predatory creatures, or magically-charged traps that consume vitality itself. He possesses the knowledge to navigate this realm. They must obey the virgin... or surrender to carnal destruction. Binding flora, sensual ooze chambers, erotic trials, and ecstasy-inducing boss encounters block their path. Compliance becomes their only option for survival. Reluctant submission transforms into desperate attraction as the girls they dismissed discovers unexpected depths in their unlikely savior—the inexperienced boy who commands their fate within these corrupted halls.
