Big-breasted mother, Yukinatsu Aoi. In a single-parent household, she has troubles with her beloved child. Literally, her son can't wean himself off her breasts. No matter what she does, the second thing he says is always 'breasts.' Her teenage son ends up groping her overly ample breasts. However, she inadvertently enjoys it. While masturbating to soothe her heated body, she gets caught. Since that incident, her son continues to grope her breasts from behind even while doing chores, regardless of her frantic pleas of 'No, stop it...!'
