El perro (1977)

A political prisoner escapes from a South American dictatorship and attempts to regain his freedom. During his escape, he is relentlessly pursued by a ferocious dog thirsting for revenge.
At the forty-third minute, we can admire Yolanda Farr naked in a beautiful sex scene in bed with a man. After sex, the two actors are standing at the front door, looking at something in the yard. Yolanda has put on a white shirt, but it is open at the front and we can see her breasts. At the eighty-ninth minute, Lea Massari shows us the profile of her breasts as she gets out of bed, where she has just had sex with a man. At the one hundred and first minute, we admire a rare topless shot of Lea Massari, who is getting dressed in front of a mirror while talking to a man.
