A subjective thing that can realistically taste the infidelity mood of a married person. The mistress has outstanding color and tech. You will be enveloped in a world of only the two of you, "you" and Yu, who came to the onsen inn by incognito. You can overcome the limits of your patience with moist mating and Yu's entangled fellatio, and finally feel like an M-man kun who will be. "I don't hate the smell of your semen," Yu whispers. A day and a night of over-the-top, serviced, dream-like and intense infidelity!
