Meirin grew up in loneliness, seeking happiness through marriage to a man with a child, but was instead met with extreme sexual abuse from her stepbrothers. The older brother forces her into shameful masturbation using empty bottles, while the younger drags her into the bathroom and makes her perform full-body washing services, enduring anal licking and deep-throat creampie ejaculation. Even during dinner, she suffers forced urination, creampie ejaculation on her tongue while wearing an open-mouth mask, and tight M-shaped bondage that torments her big breasts—her days are an endless torture. Even while sleeping, the perverted brothers sneak into her bed, immediately forcing double blowjob sessions, being continuously penetrated by two cocks, and enduring creampie incest as her extreme ordeal persists.
