Older Sister Dormitory - Thrilling Cohabitation with Two Sexy Sisters

A dating simulation game featuring two older sisters, Akane and Shion. The player engages in conversation-based intimacy building, selecting from four dialogue topics each turn to gradually deepen relationships and increase a desire gauge. As intimacy grows, the protagonist becomes bolder and previously awkward topics become available. The game features animated and still-image sexual scenarios tailored to each character's personality—Akane is cheerful and affectionate, while Shion is reserved but gradually opens up. Success in conversation unlocks increasingly intimate encounters and reveals hidden facets of each character.
