My Muscle System in the Mage World - Chapter 301: Refining the spell

Kota Sakamoto—virgin weeb, social reject, and hentai game addict—gets sucked into a perverted dungeon world straight out of Carnal Labyrinth EX, the 18+ erotic strategy game he secretly 100%-cleared.The catch?All eight of his hot classmates and their strict MILF teacher got dragged in with him.The other catch?They hate his guts.Worse still, this dungeon world is exactly like the game—every level a twisted, orgasm-fueled survival puzzle where failure means death by overstimulation, lust-monsters, or trap-triggered climaxes that literally drain your soul.He’s the only one who knows how to survive.They either listen to the virgin... or moan themselves to death.Bondage plants, lewd slime traps, fetish trials, and orgasm boss fights await—and the only way forward is obedience.What starts as reluctant cooperation turns into obsession, as each girl slowly falls for the boy they once mocked...…the virgin who’s now their dungeon master.

My daughters started regressing out of nowhere, stirring up a storm because they missed their mother.…But I haven’t even married yet, let alone have any daughters!?

Reincarnating to find two beauties laying on his lap, Jake found out that he was a Demon Baron with no bloodline. Exiled from the Hell to the human world, Jake was left with a small dungeon and his two servants with almost no monsters under him.

Just when he thought things weren't good for him, he suddenly heard a female voice in his head.

[Ding! Welcome host to The Sin System.]

[Please spin the Sinner's Roulette to unlock your first Sin.]

“This is...” As Jake instinctively touched the dark disk that came in his sight, the disk started spinning and stopped five seconds later. He heard the system's voice again.

[Ding! Congratulations, you have unlocked the Sin of Lust.]
