On her 28th birthday, she received the words from her husband, "Let's start trying for a baby soon," and together they purchased a 3LDK detached house in the suburbs of Tokyo. To everyone around her, it seems like she's living a perfectly smooth life. Yet, deep inside, she feels restless. After quitting her job at the apparel store she used to work at, being alone at home makes her pussy ache. She finds herself obsessively masturbating during the daytime, feeling utterly miserable about it. Even though she knows it's immoral, she can't suppress the overwhelming urge to embark on a wild journey of nonstop sex.
