Demon King’s Feminization: Rookie Ruler Crushed by Brutal Hero

Synopsis

Newly crowned Demon King Ubel confidently invades the human kingdom alone, believing her demonic power far superior to weak humans. However, she’s swiftly defeated by the Hero.

The castle’s Anti-Demon Division has developed an experimental drug. Why not test it on the Demon King?

The Hero forcibly makes Ubel drink the potion. Her body transforms—her penis shrinks, becoming a clitoris, her body feminizing completely. The Hero begins teasing her newly formed pussy, and despite her resistance, Ubel climaxes repeatedly from unfamiliar sensations.

The Hero grins wickedly: “This drug creates a functional womb… you might even get pregnant.” Despite Ubel’s desperate pleas, the Hero penetrates her virgin pussy, thrusting intensely while playing with her breasts.

Days pass with the Hero repeatedly violating the Demon King. When she doesn’t return, her Four Heavenly Kings use forbidden teleportation magic to rescue her—only to arrive at a horrifying sight. Ubel is restrained, legs spread open, being violated by multiple humans simultaneously. She’s become a complete fuck toy.

Shocked, the Kings attempt rescue, but the Hero easily defeats them and forces the same drug upon them. Soon all five are being used as sex slaves by the humans.
