I, as a tutor, have sex with my slender, large-breasted mother, who is unsatisfied with my explicit seduction. (Mitsuhime Mio ROYD-123)

As a tutor, I was targeted by a student's mother who would call me out whenever she had a spare moment and beg for my penis. The widowed mother, sexually frustrated, would have sex with me whenever the student wasn't home. As her visits increased from once a week to three times a week, the student happily remarked, "My mom's complexion improved after the teacher came."
