At a gathering of coworkers at home, the conversation turns to Miwako, a beautiful married woman. Her husband, praised for having such a skilled and gorgeous wife, becomes the target of envious glances. The coworkers grow increasingly aroused by the image of Miwako. Later, when they visit again and find her absent, one of them discovers Miwako's panties on the floor. Using the panties as leverage, they force her husband to confess in detail about their intimate sex life. As he reveals various explicit acts they've engaged in, the coworkers can no longer restrain themselves. Just then, Miwako suddenly returns home—and before she can react, the men pounce on her aggressively.
