30-year-old housewife Yuki Yanagi. In her fourth year of marriage, she and her husband have been actively trying for a baby twice a week, yet there are still no signs of new changes in their relationship. The reason? Her husband's excessive masturbation has led to weak vaginal tightness, making intercourse unsatisfactory. Initially worried that she might be at fault, Yuki eventually discovered the truth—her husband strongly prefers masturbation. Since he can't climax without hand stimulation, it's become routine for Yuki to finish him off with a handjob. Wanting to become better at pleasuring him, she's been studying AVs and refining her sexual techniques. On this day, showcasing her perfected handjob skills, Yuki also longs to feel pleasure herself, as she deeply satisfies her husband in ways their usual sex life doesn't, giving him an entirely new level of fulfillment.
