I have doubts on the release date of this movie to be '74 and not '70, nevertheless it's a classic example of porn of the good olden days. This movie has a mediocre storyline. A housewife with not so happy sexual life goes to a psychiatrist and explains in details about her sexual fantasies.
There are no credits shown in this movie. It starts with Uschi Digart running with her big natural t***. There is a hot scene on a boat when the protagonist peeps in and fantasizes. Another one in which two women compare a di*** with an original one and end up using the later. Also another one was a hot scene in the bed where the girl wakes up her boyfriend and convinces him to have s**. And yes it stars John Holmes the king of porn.
You may not get a good print of this movie because it is about four decades old but it is worth watching. My rating a 7 out of 10.
