A Dirty Western (1975)

Set in the western plains circa 1890, A Dirty Western opens upon a series of unique visuals and effects depicting the escape of three dangerous convicts. It's a torrid story of abduction, eroticism, and lust in the wild and woolly west. You'll be back in the saddle again as Luke savagely attacks the virginity of Maria, as the girls are forced to perform an exhibition of lesbianism. Meanwhile, back at the ranch, the posse closes in on our evil trio in a spectacular orgy of lust and more lust...It's about time somebody made A Dirty Western!
