The violent ultra rotor attached to a beautiful girl is suddenly turned on in public! At the request of her older boyfriend, Kokoro-chan has a monster rotor attached to her undeveloped pussy. There's no way that her secretly lewd body, which comes to orgasm in seconds during a test run, can withstand humiliating play inside a family restaurant. She ignores the protests of ``It's really no good...'' and keeps flipping the switch.
