Megumi and her husband used to enjoy nightly intimacy, but recently her husband has been suffering from repeated erectile failure, making their connection feel increasingly hollow. Unfulfilled, Megumi began masturbating alone, no longer thinking of her husband. Her son secretly recorded her doing so, and watching his mother like this stirred intense emotions within him. One day, Megumi went out shopping. When she returned, she couldn't find the door key and desperately held in her urge to pee. Ringing the doorbell, her son opened the door. As she tried to rush inside, she suddenly lost control and urinated right there in the entryway. That night, Megumi pleaded with her son, "Please don't tell anyone about what happened earlier." The son silently nodded—but in return, he pushed his mother down and demanded the same intimacy she once shared with his father.
