The hours while her husband was at work were the most agonizing for Yumi. For her, this time was filled with humiliation and shame, a lewd and degrading period spent as a sexual pet. With her weakness exposed, Yumi was continuously toyed with and defiled at the man's whim. His demands gradually escalated, forcing her into increasingly depraved acts. Even when she resisted, her body betrayed her feelings, made to climax and be ruined by him. Worse, the unemployed man began devising a deranged plan: to rent Yumi out as a pet for other men, making her mate with them in twisted threesomes.
