A middle-aged woman from a housekeeping service comes to the house while the client, who lives in a single-parent household and is unable to do any housework at all, is away. She immediately changes into comfortable pants and gets to work cleaning the room, but her shy son, who doesn't know how to talk to her, is watching her from the shadows. Thinking that no one is around, the middle-aged woman works while swaying her plump, tight-fitting ass from side to side. The lewdness of her pants, which fit her so tightly that her panty lines are clearly visible, makes the son's virgin dick instantly erect!! He can't help but attack her from behind and forcefully insert his penis into her from behind.
