The secret of ordinary married woman Saori is her abnormal libido. After her husband goes to work, she enjoys rich sex with a student Makoto and a lewd slut play, and in a place like an orgy club, she is squid with five men, a rotor, and a vibrator, and goes crazy in search of 3P. At the end, Saori masturbates in front of the man who trained her for sex, and shakes her hips at the woman on top posture to explode her desire.
