He also has new abilities which he can use as he finds many characters there, but he had a different preference than others, in that he likes feminization very much. And now that he is in a hentai world, surrounded by the hentai characters, his goal is to feminize the male characters in the world and turned them into his slaves while also getting their girls as well. This is the story of the Master of Femboys! A/N: I have become interested in feminization hentai and so I am writing this for it. Hope you enjoy.
