El Satario, also known as El Sartorio, is the name of one of the earliest surviving pornographic films. It was supposedly produced in Argentina in 1907, and includes possibly the first use of extreme close-ups of genitalia. Others date it to 1930s Cuba.
A group of young women is frolicking in the countryside. Then the devil appears and forces one woman to receive and perform oral sex and then have sex with him. Then the other women come and put him to flight.
