Married woman Chiaki, 30 years old. With fair skin and a voluptuous, huggable body, she debuts as a newcomer at a delivery health service. Lacking experience, she hesitates slightly when the client who booked her with a video shoot option pushes for full intercourse, but she bravely continues the session. Despite her clumsy touches, her sincere and affectionate approach captivates the man. Her black stockings are torn off, her genitals teased and played with, making her moan in pleasure as her excitement steadily builds. Repeatedly brought to the brink of orgasm with a vibrator only to have it pulled away, she eventually pleads, "Make me cum." Her desperate begging sends the man's arousal soaring beyond control. Unable to stay satisfied with grinding, he pushes for penetration—and when she agrees, she's thrust into ecstasy, climaxing again and again from the pounding of his cock. Her innocent demeanor and honest, unfiltered reactions to her first real sexual experience deeply stir the man's emotions.
