Miki does housework in a lewd manner... her son Mikio looks at her with lewd eyes... "Mikio, you're looking at my body with lewd eyes again..." says Miki, a perverted mother who shows off her lewd female body to her son and plays with it. Miki is fixated on Miki's buttocks as she stands on the stepladder to change the light bulb, but he can't hold the stepladder down and falls to the floor with Miki... At that moment, Mikio's hand is on Miki's chest... Mikio comes to his senses... but Miki's sexual desire is ignited by Miki's sudden touch of her chest and she becomes aroused.
