A married woman torn between shame and a sense of moral transgression wonders if she can fulfill her husband's cuckolding fantasy. The organizer of a swinging enthusiast circle proposes a "cuckolding" request. The partner is Y-ka (31 years old), in her third year of marriage. She struggles to muster the courage, and even after arriving at the hotel, she breaks down in tears during a kiss. Yet her body responds sensitively, and despite feeling embarrassed about her soaking wet pussy, the moment she says "my heart is pounding" as the dick is inserted, she climaxes multiple times. One month later, at her husband's request, the married woman comes to be fucked while wearing her office uniform. Already showing a lustful expression from the toy she inserted in the station restroom, she moans as her ass is spanked. Thrust by the dick, she writhes in pleasure, unable to think of her husband, and screams as she orgasms repeatedly.
