Wife Yukina used to work as an office lady before meeting her husband, during which time she was deeply involved in a passionate affair with her ex-boyfriend—who is now her brother-in-law. In the quiet office space, they repeatedly indulged in intense sex, including deep throat blowjobs, titty fucks with her F-cup breasts, and rough creampie sessions where he would cum deep in her throat. Just seeing her brother-in-law stirs up memories of their past, igniting a burning desire within her. When he stays over late at night, she can't help but moan softly while having sex right beside her sleeping husband. As he licks and caresses her entire body, she loses consciousness in pleasure, surrendering herself completely to the ecstasy of his huge cock, writhing in torment as she's drenched in a massive facial from this forbidden, incestuous encounter.
