Molester Invisible Man III: Indecency?1979

What if a secret potion could instantly turn you into an invisible man!? Rape a nun, peep into the women's bath, and even butt in on a lesbian encounter… It fulfills every man’s secret desire that everyone has dreamed of experiencing at least once! This is the third installment of a slapstick, farcical pornography comedy, depicting the wild adventures of a man who accidentally discovers a secret potion that makes him invisible. Taihei transforms again into the elusive invisible man, offering us an unvarnished look into a world of unabashed lust. First, an insidious lesbian encounter takes place between two nurses. When the invisible Taihei intrudes on the scene, he goes after both women… Next, he unleashes his mastery of molestation against a nun at a convent. Still unsatisfied, he invades the women’s bath at a public bathhouse, and a series of provocative, titillating scenes unfold as he exploits the effects of the invisibility potion.
