One day, the son returned home earlier than usual and witnessed his mother, dressed in a lewd outfit, seducing a delivery man at the front door. "What a shame, while my dad's on a business trip... But I never thought my mom had that side to her..." From then on, the son began to peek at his mother's secrets on a regular basis. The son couldn't contain his excitement at his mother's lewd behavior as she manipulated men one after another and ran off to have affairs!
