The one who came for the private filming of P-activity was college student Suzune. She has a clean and innocent atmosphere, but when the old man's persistent cunnilingus flips her switch, she sucks the old man's dick wildly. When inserted, she exposes her slutty true nature and cums with intense, beast-like moans—the gap is irresistible. This is a documentary capturing real sexual intercourse between an abnormally lustful old man and a pure young girl.
