Porn Game: Koisoft - Sanctum Protocol Demo

A NSFW visual novel of dark sci-fi and mystical erotica.

After a global event opened portals to corrupted pleasure, the world was changed forever.

Though life goes on, lustful demonic entities now roam freely... The Order of the White Lance — warrior nuns trained in divine combat — stands as humanity’s last line of defense.

You were just another civilian... until you purified a succubus through sex — and survived.

Now, your memory is gone. Only a voice remains, whispering from the shadows: Lilith. The nuns who find you can’t explain what happened — but they quickly realize you might be... useful.

Very useful, to keep purifying their enemies.
