Mamagoto

A young man returns home after years away in university dormitory life, only to find his family dynamic has become strained. His mother's friend and neighbor, the married Kyoko Kawashima, notices his loneliness and offers comfort—though her intentions are far from purely sympathetic. She begins seducing him through intimate 'skinship,' hoping to make him exclusively hers. When his mother Chikage discovers this, she grows desperate to reclaim her bond with her son, but her efforts quickly escalate beyond appropriate boundaries. Soon his tsundere younger sister Aki and Kyoko's daughter Yukimi join the fray, leading to an increasingly intimate and competitive dynamic within the household. This eroge explores the tangled relationships and sexual tensions that arise when family bonds blur into something far more complex.
