43-year-old Yukie has been married for 17 years and has one child. She hasn't had sex with her husband in four years. Although she deeply enjoys sucking cock, her husband never fulfills this desire, leaving her to satisfy herself through masturbation four times a week. She regularly fantasizes about large dicks while pleasuring herself. Having never experienced infidelity before, her longing to feel an exceptionally big cock is growing stronger. To fulfill Yukie's fantasy, she meets a top AV actor in a luxurious, high-end hotel room. Seeing his massive cock up close, she gasps in awe before he finally penetrates her. Overwhelmed by its size, she moans uncontrollably, experiencing pleasure unlike anything she's ever known.
