Succubus Research Diary ^1.5.1

Game update on 06/09/2021. Created by Arcus Plume. Available for download in en.

The daring explorer Serena and the kindhearted succubus Nerisha meet by chance in the depths of the Underground, as Serena accidentally stumbles upon Nerisha's doorstep. After learning of each other's circumstances, they strike an unusual deal. A deal that involves the two of them having lots of sex...
Spoiler: Characters
Nerisha is a young adult succubus who has never had sex. This is something of a problem to her because succubi can't fully develop their magical powers unless they have some sweaty fun with humans or other humanoids. However, having high ideals of equality, Nerisha is unwilling to get herself a sex slave as most other succubi do.

Serena is a human explorer who got separated from her expedition after something unfortunate happened. She's a mature woman with plenty of sex appeal that she doesn't hesitate to put to good use.

MATURE CONTENT DESCRIPTION:

This game contains explicit depictions of consensual sex and uncensored genitals. All characters depicted are 21 years old or older.

The story takes place in a female-only fantasy world, in which all women possess the intrinsic magical ability to become temporarily "futanari," i.e., grow male genitals (note: it is possible to finish this game without playing any futanari scenes).

The adult scenes in this game are either female x female (~70%) or futanari x female (~30%).
