Every day, Sayuri, a milf mother, received massages to relieve the fatigue of her daily life. However, with her husband constantly working late, she rarely had her lush body satisfied and continued to endure lonely, unsatisfied nights. Witnessing her state day after day, her son Junpei gently offered one day, "You're always so tired—let me give you a massage today." Grateful for her son's kindness, Sayuri happily accepted. But Junpei's massage was more than mere care—he repeatedly rubbed her lower breasts, gripped her soft buttocks, and pressed her underwear against her private area while spreading her legs. Overwhelmed by pleasure she hadn't felt in ages, Sayuri surrendered her body to her son's touch.
