This married woman named Maki Usami, age 33, has been completely consumed by her pleasure addiction. She confesses that she can't stand being around her 4-year-old son anymore due to his constant neediness, causing her sex life with her husband to plummet since giving birth. As a result, she now masturbates at least twice daily on her smartphone while watching AVs during breaks between housework and childcare. However, lately she's noticed that these quick fixes aren't satisfying her like they used to, especially compared to what she sees in the pornography. Determined to release years of pent-up desire, she leaves her child with relatives so she can finally indulge in an ultra-horny wife's fantasy!
