About Sisters in Sin 🔞
You play as a demon posing as a charismatic preacher who arrives at a remote monastery with orders to corrupt it from within. What should be a straightforward corruption scheme becomes far more complex when you discover that the nuns are themselves conflicted, harboring secrets and desires that contradict their vows. The game unfolds through management of daily schedules, dialogue choices, and strategic interactions with both the sisters and visiting donors, each decision pushing characters further along their own paths toward moral compromise. Like House Party, progression hinges on understanding individual personalities and manipulating circumstances to your advantage.
Sisters in Sin combines casual simulation with light role-playing mechanics, tracking relationships, unlocking scenes, and expanding monastery facilities as you accumulate donations. Character art changes to reflect each sister's evolving state of mind and wardrobe, visualizing their spiritual unraveling. The narrative branches based on your choices, offering multiple routes through the story depending on which characters you focus on and how aggressively you pursue corruption.
The full release launched in April 2026 on Windows and includes 29 language options. The game is designed to be playable one-handed, prioritizing accessibility alongside its adult themes of manipulation and transgression.
Developer's description
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.
