The Tachibana couple had to get a loan from their uncle after their business failed. The condition of the loan was that his wife, Kyoka, take care of his personal needs. Kyoka tries to refuse because she doesn't like her uncle, but she accepts because she sees her husband bowing his head and begging... Her uncle, who plans to make Kyoka his own, forces her to change into a maid costume and sexually harasses her every day. And his uncle's sexual harassment escalates day by day, and he begins to do whatever he wants with her body, using secretly filmed videos as material.
