Niityan's lens captures Kaori Sato, her lithe body clad in a revealing swimsuit, as she lounges poolside. Unbeknownst to her, her every move is recorded.

Her touches grow bolder, her moans louder, as she brings herself to a shuddering orgasm, her juices staining her suit, a secret only the camera and the unseen observer share.
