Workout in the Back Room
These are shots from a vintage smut magazine called Workout in the Back Room. They appear to be outtakes from a porn film, but I could find no information about it online. As well, there's nothing in the publication about any movie, if it exists under another title. The plotline seems to have something to do with various blokes showing up at a construction site and getting it on.
