Takuya, a young man who loves cars, enjoys driving on his days off. The person he admires is Lina, a beautiful woman who also loves cars and has a voluptuous G-cup bust. Takuya takes the plunge and invites Rina on a drive date, and she readily accepts. The two decide to head for a coastal driving course a little far from the city.
Inside the car, Lina’s smiling face and lighthearted conversation create a peaceful atmosphere, but Takuya gradually begins to notice Rina’s plump chest. As she sits in the passenger seat, the casual gestures she makes from time to time stimulate Takuya’s heart. At the moment of sharp turns and acceleration, Lina’s breasts swayed and Takuya’s gaze was fixed on her. As if enjoying his behavior, she begins to behave in an even more seductive manner.
