Kaho Kana says she has long been interested in adult videos. Her first encounter with AV was during her student days, when she accidentally came across a lesbian video owned by her older brother. At the time, she knew the term "sex," but was unfamiliar with the concept of women being intimate with each other, which left her deeply shocked. Since then, watching AV became a hobby, a habit she continued even after marriage. Her husband also enjoys adult videos, which eventually inspired her to pursue an appearance in one herself.
Mio Tomio was dissatisfied with her sex life with her husband and felt her sexual desires were unfulfilled. For her, sex was an expression of love, and her husband's lackluster performance made her feel as if she wasn't truly loved. In this emotional state, she coincidentally reconnected with an ex-boyfriend and began a physical relationship. Overwhelmed by the pleasure she experienced, she became addicted to the sensation and started seeking new relationships to satisfy her sexual needs.
