Coming Apart (1969)

Rip Torn plays a psychiatrist who's having a bit of a mental breakdown in Coming Apart (1969). To document his dementia he rents a room, installs a hidden camera, and proceeds to film his various dalliances with the fairer but just as freaky sex. Blonde neighbor Lynn Swan does a striptease that ends when she asks for money to get more intimate. Even breast lovers will have a hard time enjoying Lois Markle's cleavage, which is scarred with cigarette burns. There's an orgy, too, but it's Sally Kirkland who steals the sexy show. She strips naked, masturbates on Torn's leg, and then blows him. Too bad the POV is all from that stationary hidden camera, so all you see is the back of Sally's bobble-head.
