Spending a Month with My Sister

Spending a Month with My Sister is a 2D animated adult visual novel for players who want a short, straightforward incest-themed story. The tone stays close and personal, focused entirely on the two characters at its center.

Gameplay

Play centers on scenes between the protagonist and his sister, moving forward through animated 2D sequences rather than open exploration. There's no route management or side content to track — the focus stays narrow and direct, built around a small set of encounters rather than a larger loop.

Features

• Animated 2D artwork throughout
• A compact, character-focused adult story with no branching systems to manage

Notes

The content includes non-consensual and sleep-sex themes alongside the incest focus; readers sensitive to those subjects should be aware going in.
