The Pleasure Shop on 7th Avenue (1979) Joe D'Amato

Two low rent hoodlums hold up a pharmacy in New York - unfortunately for them it is under the protection of the local mob boss, and they flee with $5,000 and hide out briefly in a Porno Shop run by the good looking girlfriend of the local gang boss. She offers and performs oral sex on one of them to let her escape, but they take her hostage anyway, and drive off in her car to meet the black hustler who had set up the job. The three criminals decide their only option to escape the mob is to drive to Canada and hide out, and they plan to spend one night of the journey indoors by breaking in to an empty country villa near the border.
