The mysteriously seductive Reika Kudo takes part in a series of masturbation experiments. What does she picture while touching herself—a muscular man, a handsome face, or a huge cock? More importantly, how will she react if a real cock penetrates her just before orgasm? As she starts rubbing, her hips writhe and her moans grow shamelessly intense. Her face melts with pleasure, her swollen areolas deepen to a salmon pink, and her neatly groomed pussy becomes soaked with juice. She pushes in a toy and twists her hips even harder. Then, at the brink of climax, a cock slides inside—but the rest of her reaction is saved for the video.
