Trap Dungeon Lord in the Multiverse

Reincarnated into a dungeon as a creator, how will Lust fare against intruders? How will he come to power using the system, and his dungeon inhabitants to his advantage. How will he become a creature known and feared throughout the universe, though still shrouded in mystery as his exact identity remains unknown? Oh, did I forget to mention his avatar is a femboy? Oh, and that he gains more power through lustful activities? Oops… ==================== MC is a femboy! The mc will have sexual relations with both men and women, and I plan to give him a body modification ability that allows him to become both man and woman somewhere in the story. (Most likely just feminine man and masculine man) This novel will most likely be predominantly sexual, and fictional characters will appear from time to time as the story will probably be focused on dungeon creation and expansion. . . Foot kink will most probably be included!
