Four years ago, Makino married a successful lawyer, and since then has enjoyed a stable, fulfilling life with no financial or marital complaints. However, the reason she entered the adult video industry wasn't mere curiosity or financial need, but because her sexual desires have steadily intensified with age. As her husband's work schedule increasingly left him away from home, she found herself watching AVs and masturbating more often. Watching the actresses' expressions and their ecstasy-filled performances only heightened her awareness of her own unmet desires. Although they have sex once a week, the frequency has gradually decreased over time, leading to growing dissatisfaction in her relationship. Faced with this, she chose to fulfill her sexual needs by appearing in adult videos, stepping onto a new path in her life.
