A film dedicated to closely observing Hazuki Amamiya's asshole, rear hole, and anus. Even the cutest girls have this part, and the highlight is counting the wrinkles and enjoying its twitching expressions. Without unnecessary penetration or stretching, viewers can calmly appreciate the details. By dressing her in white or blue swimsuits and lifting the crotch area, her anal region can be examined more carefully. The girl's facial expressions and the condition of her anus unfold like a movie.
