Newcomer spa therapist Natsumi notices that the client, while receiving a head spa treatment, has an erection and is asleep. Natsumi, who currently has no boyfriend, cannot suppress her sexual desire and starts to play with her own genitals, sucks on the client's penis, and eventually begins having sex. The client inevitably wakes up, but his slight rationality upon waking is defeated by his overflowing sexual desire, and he follows his instincts, thrusting his hips. "Please keep this a secret from the shop," "Make me feel even better," Natsumi's teasing words further excite the client. They engage in cunnilingus, handjob, and a 69 position as if remembering, elevating each other's pleasure. They climax with a deep thrust in the missionary position, but Natsumi still begs, "I'm still not satisfied..." "I want more." Ignoring the time, they eventually have a second internal ejaculation. Natsumi even performs a cleanup blowjob, providing the client, despite being a newcomer, with the ultimate spa experience.
