I woke up naked and all alone in a summoning circle, the only clue to my past is a demon summoning book and the hazy memories of a world very different from the one I find myself in now. I should probably be more concerned with the changes that have befallen me but I can't help but be excited to explore this new world with the new lovers I've found. After all, I'm apparently the Origin of Succubi, my actions will shape my new race in this world and all I know for sure is that I'm horny as hell.I update twice a week on Sundays and Wednesdays!Note: This novel contains a rape scene early on in chapter 8, this is not a frequent occurrence and it is not glorified or treated lightly. This is an event that affects the protagonist though so there are occasional references and allusions to the event throughout the series. The novel is loosely a genderbender but the Trans tag is for a character other than the protagonist.The series primarily features anthropomorphic characters including the protagonist which may be a turn off to some readers. The references to things like snouts and muzzles happen relatively rarely though, so you may be able to picture the characters as monster girls instead.
