Seduction Quest ~Succubus’s Seduction and Enticement~

Shun wakes up in a locked cell, and the succubus standing over him explains, quite cheerfully, that she's here for a full extraction. The door turns out to be unlocked, which is either luck or a trap, and the rest of the mansion is packed with more of her kind.

The plot is simple and doesn't pretend otherwise: get caught, get milked; stay clever, stay intact. Every hallway and room is another chance for Shun's escape attempt to go sideways.

Play is sandbox-style exploration through the manor, sneaking past or getting cornered by succubi as you look for a way out. Getting spotted isn't a game over so much as a detour into exactly the scenario Shun was trying to avoid, and the mansion doesn't get any less dangerous the longer he stays.
