Brazzers has its series "Big Tits at Work", and latterly the same content under the title "Overworked Titties", and French porn label Dorcel also covers working women in a variety of professions, including this obscure release about ladies working as grease monkeys in a garage.
An actress whose work I admired several years back but who failed to make the Dorcel A-List, Jessyca Wilson, stars as "The Garagist", working at an auto repair shop but actually undercover for her uncle (played by director Pascal Lucas), assigned to find out what's up there. She quickly discovers it's lots of sex on the job, including interracial action with Black employee Eddy.
Other oversexed employees include Max Casanova and manager Phil Hollyday, and Jessica also has a hot sex scene with customer Ricky Mancini. A corny porn trope is trotted out for two separate scenes: sex on car hood.
It's lightweight porn, with malice torn none but a very traditional form of misogyny regarding the ease with which the busty femme workers, including Wilson, go beyond fraternization to instant humping with co-workers and clients. It's definitely a B movie by Dorcel standards but plays well -all that's missing are the often overly serious mood and certainly the extremely glamorous lingerie of a typical production.
