Dragoness, Mystic Warrior, Elf, Mandragora, Thief, Slime Girl... to save the world the hero challenges each vixen of evil! (and gets gleefully r*ped by her when he loses)

An epic, erotic fantasy world. He is the naively driven hero who wants to vanquish villainy at its source: the Dragon inhabiting historic ruins! It's a quest of many meetings, from normal to protective monster girls, and for some reason they're all sexual...

Can he rise to victory? Will he protect the peace of the world!?

Or will he falter, fail and die in a glorious blaze of sex...?
