Suzu No Kashima, a 30-year-old mother of one, has been married for three years and her body is yearning for new stimulation. When it comes to sex, she has a strong preference for doggystyle, desiring to be taken from behind from beginning to end—an entirely natural craving for a woman who loves being mounted this way. Meanwhile, her husband values romantic intimacy, cherishing eye contact and emotional connection during lovemaking. This mismatch in sexual desires has brought their daily life to a standstill, sparking new emotions within Suzu. The desire for pleasure over love begins to shake her heart. Finally, her long-suppressed craving for rear-entry sex is set to be unleashed. What she seeks is not just animalistic pleasure, but a deep sense of satisfaction and release beyond mere intercourse.
