Lust Demon King: Use Your Body to Conquer Girls

[Note: The cover is the succubus Lilith, Charles will meet her in the arena and conquer her to gain her love and loyalty. At the same time, I will attach pictures of female characters in the comments of the chapters, these pictures are made through Stable Diffusion. ] Every day, I update the content of a chapter. If you give me the Power Stone, I'll update more chapters. The protagonist of the story travels to the world of sword and magic. He became a thief, not a nobleman and a prince. He had the honor of being the successor of the Demon King of Lust. However, being the heir to the Demon King of Lust did not directly bring him wealth and power. Charles, he needs to use his wisdom and ability to upgrade the level of the demon, so as to unlock more talents and abilities, so as to strengthen himself. Charles' story begins in an underground arena where he meets powerful girls and fights them in erotic battles. Charles would then develop an intimate relationship with the girls and then begin his adventurous life with them. I hate the kind of novels where you travel to another world and become a noble prince. Because it's not challenging for the protagonist or the reader. If you want to read this kind of novel with a light beginning, then I suggest you choose other books.
