The cast, including John Leslie, Hershel Savage and Sue Nero, is entirely American apart from Julia Perrin, who plays a French au pair girl in the USA who becomes the target of sexual harassment in every household in which she works.
After trying out and rejecting a family who live in revolting conditions with cats in every kitchen cupboard, she goes to the house of a family where she watches the mother having sex with her lover (Hershel Savage) in the living room. As Julia masturbates on the staircase she is surprised by the host who immediately forces his huge dick into her mouth. The only way out is biting his penis which makes him more cautious in future. A sex session with the daughter and her boyfriend follows.
The next family features a horny old grandfather sitting in a wheelchair and wearing General Custer's uniform. A maid (Sue Nero) takes special care of him as she gets her big boobs and her mouth fucked by him.
The last 'family' turns out to be a single-person household (John Leslie). (I'm also looking for an au pair for my single household - where can I order her?). After some passionate sex she marries him.
