Aqui, Tarados! (1981)

An anthology in three episodes, all involving some prohibited sexual perversion. In the first episode, "A Tia de André", a teenage boy gets sexually involved with his Balzakian aunt. In the second episode, "A Viúva do Dr. Vidal", a widow decides to take revenge on her abusive husband by having sex with a lover over his coffin on the day of his funeral. In "O Pasteleiro", an apparently shy and kind Chinese man brings a prostitute to his apartment, but what appeared to be just an odd client ends up becoming a cruel and sadistic psychopath.
