For her fifth release, now that An-chan has become more comfortable with filming, the scenario takes an entirely new twist. Without her knowledge, we set up a prank to test whether she's genuinely feeling pleasure like when she first debuted—by giving her a surprise "instant fuck." Her shocked reaction to the sudden cock insertion—"What is this!?"—is pure and captivating. Throughout the video, An continues to be caught off guard in various situations: during a shower, a magazine photoshoot, and even a live chat session. Her innocent expressions and honest reactions are the highlights. With unpredictable pranks waiting around every corner, this is a must-watch from start to finish.
