Overview

Sisterly Lust is a 3D dating sim for players who like slow-burn family drama with a strong corruption theme. It plays calm and personal, focused on reconnecting with people rather than spectacle.

Story

After his father's sudden death, the protagonist is approached by the mother he hasn't seen since his parents' bitter divorce years earlier. She invites him to move back in, meet the three sisters he was separated from, and try to become a family again. He agrees, though the reunion brings old distance and new tension neither side expected.

Gameplay

Play centers on daily life in the household, talking with and getting closer to the mother and sisters through dialogue choices that shape trust and attraction over time. Interactions unfold gradually across in-game days, with some scenes gated behind relationship progress rather than open exploration. Choices lean toward a single steady path of growing intimacy rather than branching storylines.

Features

Rendered 3D character art with consistent family cast throughout
Dating-sim structure built around one household and its unfolding relationships
Themes of blackmail and jealousy woven into the corruption arc
Optional toy-sync support for compatible hardware during certain scenes

Notes

The game centers entirely on incest and family-corruption themes; readers sensitive to that focus should know it's the core of the story, not a side element.

Installation

1- Extract to desired location. 2- Click on "SisterlyLust.exe" to start playing. Incest Patch: Download from download section OR (read below): Open the developer console by pressing Shift+O and type: set_special(True) When properly patched, the title screen will show 'Taboo Edition'; if you didn't do it properly, it won't change, so double-check that the title screen changes (see below). You only have to do this once, the changes should be persistent and will carry over to new releases of the game.
