Swingers' Serenade
1999 · 24m · 7.0 on TMDB
A character referred to as "The Professor" introduces and comments on a filmed version of a supposed script from a 1960's home movie-making magazine. Even though the target audience would presumably be making the film at home and casting their friends and family, the script is an extremely suggestive tale of a housewife being seduced by a traveling salesman.
