My Wife's Cuckold Journey: Polynesian Sex in Paradise

A story-driven adult game about a married couple navigating infidelity and sexual exploration. Yuto and Tsumugi have been together since their school days, but their marriage is strained by his erectile dysfunction and unsuccessful attempts to conceive. In a bid to support her husband, Tsumugi accepts his hidden desire for cuckolding and embarks on a five-day trip with a man named Morita from an online community. The game unfolds through a gradual progression called "Polynesian Sex"—a five-day process that slowly escalates physical intimacy—punctuated by nightly phone calls where Tsumugi reports her experiences. Players follow the couple's emotional and relational journey as boundaries shift, culminating in a choice between restored intimacy or marital collapse.
