Even when a penis is inside her vagina and she orgasms, she won't let go. (Sasaki Aki WKD-007)

This slut, Sasaki Aki, in a twisting, riding position, tightly grips the erect penis with her vagina, savoring its taste. She first uses oral sex to make the penis even harder before immediately inserting it, violently twisting her waist back and forth to enjoy the lewd power of the penis. With the increasingly intense twisting, she reaches an orgasm that is incredibly pleasurable!
