Los pecados de mamá (1980)

A horny housewife finds a new outlet for her sexual cravings in the saucy Spanish melodrama Los Pecados de mama (1980). Gloria (María Kosti) is a middle-aged nymphomaniac trapped in a loveless marriage to the hapless, affluent Enrique (Ricardo Merino). When she’s introduced to her servant’s beefcake fiancé--a feisty young boxer--Gloria realizes that she can’t restrain herself any longer and succumbs to her carnal desires. Gloria and her male pal never boff on camera, but director Javier Aguirre makes sure to show the alluring Kosti in the throes of her longing. The baby-faced beauty cops a feel of herself both in front of the mirror and beside her lamely disinterested hubby.
