After a drunken kiss six months prior while visiting her in-laws' home with her husband Saya’s wife (Miu Shiromine), Saya nervously awaits another visit fearing a repeat of that memorable moment. Though the father-in-law might have forgotten the initial encounter—the lingering impression of his passionate kiss remains vivid in her mind—a quiet night passes without incident. However, when her husband heads out early to fish the next day,
The father-in-law approaches her again with a proposition: a substantial sum of money in exchange for another intimate session. He clearly hasn't forgotten that first kiss! Desperate for funds because her husband’s salary leaves her feeling inadequate during social outings with friends, Saya is instantly tempted. Before she can fully consent, he lunges forward to devour her soft lips.
He proceeds to lick across every inch of her body, stimulating all her most sensitive spots. While Saya tries to resist, her body betrays her will, craving more intensity than her husband can provide. From that point on, she regularly allows him to take charge, receiving cash payment each time. Even after moving back to the city life with her husband, Saya secretly returns to visit him at the countryside home just for sex and the hefty paycheck!
