Overview

Chai's Hypersexuality Diary is a 3D visual novel for players who want a character-driven adult story with some choice at the end. The tone leans reflective, framing one woman's past and present through the question of who she really is.

Story

Chai Gunderson, once an adult film star, now lives a quieter married life with her older husband Rick. That quiet breaks when she wakes to find her stomach larger than it should be, with no clear answer as to why. The story asks players to piece together her past encounters and decide what kind of wife, and woman, she has actually been, leading to one of several possible endings.

Gameplay

Play unfolds as a sandbox-style visual novel, moving between periods of Chai's life to uncover scenes tied to her history and the mystery around her pregnancy. Choices made along the way shape which of the multiple endings the playthrough reaches, and finishing a run opens up a way to start again with a different path in mind.

Features

Told entirely through Chai's point of view, with an internal perspective on her thoughts and choices
A recollection room to revisit unlocked scenes after they've been seen
A dedicated endings room for tracking the different outcomes reached
New Game+ option for replaying with carried-over knowledge of prior choices

Installation

1. Extract and run.
