Sisters in Sin is an adult visual novel (18+) where temptation hides behind prayers and desire slowly breaks sacred vows.
You play as the Demon of Lust, disguised as a charming preacher who infiltrates a remote monastery with one simple mission: corrupt the holiest place in the region from the inside.
What starts as an easy task quickly turns into a game of psychology, manipulation, and control — because the nuns are far from innocent.
Each sister has her own personality, secrets, boundaries, and forbidden fantasies. By carefully managing daily schedules, making the right choices, and interacting with visitors, you guide them on a journey from strict devotion to forbidden self-discovery.
Donations from guests allow you to expand and upgrade the monastery, unlock new locations, scenes, outfits, and story paths — shaping your own twisted version of paradise.
Sisters in Sin is a provocative narrative-driven experience focused on corruption, power, and the fragile line between holiness and sin.
