"If she doesn't feel anything after receiving a massage at a women-only brothel, we'll give her a prize... would you like to try it?" The plan is for the North Kanto Yankee couple, Kokoro (20 years old), a vocational school student, and her boyfriend Ryo(22 years old), a civil engineering worker, to challenge the game for a prize of 1 million yen... but in fact, the target is a cheeky and aggressive Yankee woman! Her opponent is KAZUMA, who works at the top-class "Roppongi Secret Fantasy" in the female brothel area, who will attack her! "I'm not feeling anything" and "I'm not cumming!" She tries to act tough, but her pants start to stain... Her boyfriend is tied to a chair and can't move, crying out, "Hey! Stop it!" The therapist with amazing skills attacks her erogenous zones, and she finally falls... and the punishment game is raw sex and creampie! He won't give up 1 million yen that easily.
