In the Vacuum Suction Clinic series, a female doctor played by the glamorous slut Kikuno Ran exclusively for Fitch resolves male patients' troubles through fellatio-focused treatment. The film explores the use of euphemisms, improvement of fellatio techniques, and the arousal from erotic sounds. Kikuno Ran's seductive appearance and erotic techniques shine in the production. However, some critique the missed opportunities in subjective shots and close-ups.
