Mrs. Kohinata, a hyper-sensitive and inherently service-minded married woman, takes on the task of guiding a younger, virgin man for the first time in her life. Always smiling and endearing, she gently leads the younger inexperienced guy, getting excited with his naive erection and rhythmically moving her hips to climax. "Does it feel good? I'm so happy...". Even if things don't go smoothly due to nervousness, or if he climaxes too early, she embraces it with a smile, truly embodying maternal warmth.
