Yuuna Mitake, a pseudonymous housewife, radiates predatory sexuality but is actually an extreme masochist who begs to be penetrated immediately, even before she is wet, because she wants to lose herself in orgasms. Her husband has a masochistic streak of his own and wants to be cuckolded. During sex she repeatedly begs for more semen, eagerly embraces anal and vaginal use, and revels in bodily fluids. Yet her family still comes first, and she repeatedly declares her lasting love for them, happily promising that they will remain together forever.
