This uncensored 18+ incest visual novel follows a young man adjusting to life with three younger sisters who constantly walk around his home naked and barge into his bathroom, until a taunting devil world princess reveals he’s a demon prince whose sisters are magician descendants, and the only way to stop his coronation is to get one of them pregnant.
Three Exhibitionist Younger Sisters & Daily Taboo Tension
1. The game opens with you moving in with your three younger sisters Haruna, Nano and Nonomi after your parents’ remarriage, who immediately show zero regard for your presence by walking around the house completely naked, popping into the bathroom mid-shower, and brushing their bare chests against your arm when you pass them in the hallway.
2. Early gameplay revolves around navigating these awkward, hyper-sexual daily interactions: you can choose to cop a feel when they lean over you for snacks, pretend to “accidentally” walk in on them changing, or ignore their obvious hints, with each choice raising or lowering individual sister affection meters.
3. Maxing out a sister’s affection unlocks private, explicit scenes starting with secret makeout sessions on the couch, escalating to full-body groping, oral sex, and raw, uncensored penetrative sex in their bedrooms, the bathroom, and even the living room when your parents are out.
Devil Princess Nerisu & Demon Prince Inheritance Curse
1. After weeks of confusing, increasingly lewd interactions with your sisters, the girl who has been taunting you in your recurring wet dreams suddenly appears in your bedroom: Nerisu, a bratty devil world princess who reveals you are the long-lost prince of the demon realm, set to inherit the throne and conquer the human world.
2. The only way to nullify your inheritance and stop the apocalypse is for one of your three sisters—descendants of an ancient magician bloodline capable of sealing demonic power—to carry your child, a condition that prompts the sisters to immediately shift from ignoring you to aggressively competing for your cock.
3. Nerisu takes great amusement in egging the sisters on, giving you lewd tips to seduce them, slipping them aphrodisiacs, and even joining the competition herself, unlocking exclusive uncensored H-scenes with the devil princess where she rides your face and begs you to creampie her to steal the throne for herself.
Sister Magic Pregnancy Endings & Unlockable Content
1. The game features four main branching endings tied to each of the three sisters and Nerisu, plus a hidden harem ending where all four women carry your children, each with unique 10+ minute long uncensored H-scenes featuring creampie, bukkake, group sex, and lactation play tailored to each character’s personality.
2. A core gameplay gimmick is the curse Nerisu casts on you at the start of the game: you cannot ejaculate unless you are inside one of your sisters or Nerisu, eliminating all side character sex routes and forcing you to focus exclusively on the main cast for all sexual content.
3. Players can unlock over 30 exclusive CGs, dynamic H-animations, and voice packs by hitting specific affection milestones, with fan guides noting that triggering the harem ending requires maxing out all four characters’ affection, finding all hidden panties around the house, and choosing to accept Nerisu’s deal to join the family.
Uncensored H-Gameplay & Taboo Fetish Features
1. All sexual content in Sister Magic is fully uncensored with no mosaic censorship, featuring hand-drawn and animated scenes with realistic breast physics, fluid movement, and moaning voice acting from the Japanese original cast, with no cuts or fade-to-black transitions for any explicit content.
2. The game includes a wide range of popular taboo fetishes including incest, exhibitionism, creampie, lactation, and light BDSM, with optional dialogue choices to engage in dirty talk, light humiliation play, and rough sex depending on which sister you are pursuing.
3. Random event triggers add replay value: you may walk in on a sister masturbating in the living room at 2AM, find her passed out drunk in your bed, or catch her trying on lingerie in your closet, with each random event unlocking unique short H-scenes and affection boosts to help you reach pregnancy endings faster.
