L.A. Lust (1980)

The trip of two European couples to Los Angeles for a friend's wedding turns into a sexy vacation with a twisted route through the lowlands of the city. Helen Duval and Lea Martini play extravagant wives left to their own devices, as husbands go on a bachelor party, who embark on one sexual adventure after another. Group scenes with anal and double penetration are one side of a lusty hike showing that Los Angeles is not just the City of Angels.
