Massage therapist San has a straightforward personality and a neat, attractive appearance. She works at a novelist's home, known for her cool demeanor and strong defenses. Despite being married, she surprisingly draws male attention, and some male clients even forcefully expose themselves and make her touch them. In such situations, San unexpectedly proves to be highly sensitive—though she maintains a cold exterior, she begins moaning lewdly once touched or stimulated. When her fair-skinned big tits are fondled, she increasingly succumbs to pleasure, her body involuntarily twitching in response. As if her mental barriers have completely broken down, her reactions grow intensely passionate, completely absorbed in the men's stimulation. Her transformation is irresistibly seductive, delivering a fully packed, thrilling experience.
