In my opinion this film has merit for 2 reasons. While most of the film sucks and is quite boring, there is a scene towards the end featuring Kathy Hilton. And while she mainly is soft core, with a little dabbing into hard core, this is the first film in which led to a male ejaculation, as Kathy puts her hand to good use.
About halfway through the scene Kathy is joined by another woman: Linda York. Best known for soft core work, Linda assists Kathy, using her hand as a stimulator. I am fairly well versed in early 70's porn, but Linda York doing hard core was a surprise to me. A little research and I found out that she has done several hard core scenes. Who knew?
As such, the combo of the two actresses working together to get their male co-star off, resonated with me. As for the rest of the film...there was no rest of the film.
