Three months ago, my mother walked out. Since she had handled all the housework, our home became a disaster, and Dad decided to hire a housekeeper. I expected some strange older woman, but the agency sent Maki, a gorgeous woman with huge tits. I had been fantasizing about using her body however I wanted when I caught her having sex with Dad in his room. Armed with the perfect leverage, we devised a plan to turn Maki into the family's obedient, insatiable sex pet.
