Taboo (1977)

A woman stands by her bedroom window. She sees three young boys playing nearby and starts taking off her clothes, revealing her breasts and butt, while her boyfriend watches from behind her. Once she is fully naked, the boys notice and stop to look. The woman starts rubbing her breasts as the boys stare. Her boyfriend tells her to stop, but she says "I'm helping them. They need me when they masterbate." He finally convinces her to stop and she draws the shades over the window.

A man sees a little girl in her yard. He unzips his pants, gets on his knees, and calls her over. We see his penis is out and he has an erection. She stares at it with a bemused expression. He tells her to take a photo of him with the small camera she has, so she does while he's rubbing his penis with a look of ecstasy on his face. He tells her to take more photos and she does.
