Stella (1977)

François, a convicted criminal, has only one obsession when he leaves prison: to make up for lost time with every woman he meets. For weeks, it's nothing but incredible sexual orgies that seem like they'll never end... until the day when she, a stunning creature of animal sensuality, appears to François as the ideal woman. He then decides to buy her back from Mario, a pimp with a bad reputation, but the underworld has other plans.
