After actually watching this work, the realistic performance using a fixed vibrator without being part of a planned project is incredibly erotic! I was initially excited by Matsui Hinako's prominent big butt in her cosplay outfit, but it's a shame that her sexy ecstatic face is hardly visible due to the butt-focused angles and wig. There was a time when incompetent directors in time-stop series didn't show faces, but it's wasteful to emphasize the ecstatic face while sticking to butt-centric shots. The scenes where she sprays squirt and reaches climax non-stop under the stimulation of the fixed vibrator are breathtaking, and butt lovers might be satisfied, but it would have been perfect if they had shot her ecstatic face from the front even in back scenes. From the drugged solo filming to the raw penis insertion, I wanted to see more of her white-eyed, ecstatic face as she got deeply into the intense sex. The overall development is hot, but I felt it could be even better with some adjustments to the camera angles.
