Lucien, a guy who has nothing but the desire to save his mother. To get strong enough, he makes a contract with the demon of L.u.s.t. And now, only by making a great harem, will he gain the power to protect those dear to him. Warning: This story contains s.e.x.u.a.l content. It\'s still a fantasy adventure (no reincarnation or system), but if you don\'t want to read a lot of s.e.x scenes, don\'t try it. Author\'s note: I don\'t consider myself good now, but a complete beginner. I hope to improve with each chapter, both my writing and story. I really hope you enjoy it. Any idea or comment is welcome.
