Sisters in Leather (1969)

Self applied "X" rating that was done simply to make people think it was naughtier than it actually was as an advertising gimmick. One of those films that were never actually formally rated and are in no way hardcore or explicit. Lots of boobs and some butts. Might be some pubic hair hidden in the shadows of one of the poorly lit scenes but I never saw any.

A man and a woman enjoy a passionate embrace in an open-top car, bathed in the warmth of the sun. The woman's large, supple breasts are exposed.

On a bright day, a couple engages in intercourse in an open-top car. The woman is topless, displaying her large, supple breasts and firm buttocks, while the man is seen sucking her breasts.

In a sunny outdoor setting, four women are seen engaging in various activities. Two of them ride motorbikes naked, showcasing their supple breasts, buttocks, and hairy pubic regions. The other two women participate in an oil massage, also displaying their supple breasts.
