About Succubus Research Diary

Succubus Research Diary is a story about Nerisha, a young adult succubus whose magical powers cannot fully develop until she has sex with humans or other humanoids. Though this is customary among succubi, Nerisha’s ideals of equality make her unwilling to take a sex slave.

Serena, a mature human explorer, becomes separated from her expedition after an unfortunate incident. The two women meet when Serena stumbles upon Nerisha’s doorstep. After learning about each other’s circumstances, they make a deal that involves having sex.
