A popular series featuring multi-day undercover filming to capture natural bowel movements. This time, we successfully approached a genuine beautiful surfer and enjoyed intimate time with her. Her home is filled with five surfboards and more than seven wetsuits, clearly showing her passion for surfing. A small camera is mounted on her surfboard, allowing viewers to virtually experience the real sensation of riding the waves. A key highlight is the scene of her defecating on the beach in her swimsuit, shot with a tense and thrilling atmosphere that captivates the audience.
