One Piece: King of the World - Chapter 14 - : Generous Cousin

Supreme Degenerate Lust System—the cheat ability that no man should have, but Alex? Alex earned it.This was the tale of a boy who wanked so furiously, so relentlessly, that his own dick—his loyal, overworked, war-torn comrade—finally called it quits and fell off.The same boy who was so hopelessly obsessed with a toothless, wrinkled gilf that he died doing what he loved—slipping in his own divine nectar like a tragic hentai protagonist with a severe addiction problem.He thought that was the end.That his dream—to finally pork a gilf—would go forever unfulfilled.But fate?Fate was a kinky, twisted bastard.When Alex opened his eyes, he was no longer lying in a filthy, crime scene-esque bedroom covered in the stains of his sins.No.He was in a new world—a world of magic, kingdoms, dragons, elves, and all that fantasy nonsense.But Alex didn’t care about any of that.Swords? Magic? Heroic quests?Boring.No, he had ONE mission.A sacred goal.A holy pilgrimage.To finally find the ultimate, well-preserved gilf and achieve his life’s work.And with the Supreme Degenerate Lust System at his disposal?Nothing would stand in his way.Not kings. Not gods. Not even the laws of nature themselves.The legend of the Lustful Fool begins now.

To reward Meng Fan for his bravery before his heroic death, the cosmos rewarded him with a ‘system’, sending him back in time to three months ago, alive.
