Yui, a beautiful wife who was kidnapped by debt collectors due to her husband's debts. The men think that Yui's wife, Yui, has more ability to repay the debt and forces her to work at an SM club. When Yui refuses, he takes pleasure in Yui, gagging her and training her to become a woman working at an SM club. She is fucked in front of her husband, and even though she looks at him resolutely, sloppy saliva overflows from her gagged mouth.
