A married woman records her own adultery sex sessions at the request of her husband, who has a desire to be cuckolded. This documentary features a wife named Yui, aged 26 and in her fourth year of marriage. As she films herself being intimate with another man besides her husband, we see her struggle between loyalty and lust. Despite initially resisting, she eventually succumbs to pleasure under the watchful eye of her husband. Throughout the encounter, she moans uncontrollably while receiving larger than average penetration. After multiple orgasms, she confesses that she enjoys being dominated by men before using a sex toy to bring herself to climax once more. Her insatiable appetite for sexual pleasure leaves her begging for more even after reaching heights of ecstasy beyond what seems humanly possible.
