Raja harem penguasa shifter

In a world ruled by shifters, humans are rare and treated as prizes to be bought and bred. Owen wakes up tied to a bed, purchased like property. Then a System binds to him: sex with woman shifters makes him stronger. Soon Owen isn't anyone's pet. He's a noble, a husband, a conqueror. But as his power rises, so do his enemies. To survive, Owen must bed more beauties, grow his harem, and claim his place at the top of a world that once caged him.
