Succubus Research Diary will get a content update in a couple of weeks. As the title suggests, the upcoming update will add epilogues to the game: one for each ending. It is to be expected that Serena and Nerisha will have some “non-platonic fun” in these follow-up episodes…
These new episodes will be similar to the Epilogic Episodes of Lily’s Handmaid in terms of content. Only that this time none of the endings will be marked as the canon ending.
I’ve already finished making one of the epilogues and the second one is well on its way. I think that I can start working on the third one before the end of this week.
Edit (2 Oct): Two epilogues completed, started working on the third one.
