A phone sex ad from a 90's VCA VHS slimcase reissue of either
Devil in Miss Jones 3 or
4.
This was one of those ads that preceded the feature film. It looked like an original video clip, made just for the phone sex service.
The theme was slightly western, with a brunette girl, a steer skull in the background, and (don't laugh) a bale of hay..or hay in general on the set.
I have no idea the actress, but she would talk directly to the camera, playing with a toy, then as the clip went along, she would be intercut with shots of her and a male model having sex as the dirty talk intensified.
The commercial was very well-done and, again, seemed to be an original production just for the spot. I could be wrong and, if I am, that would be one hell of a longer clip/movie.
ETA: Wow, I need tougher Holy Grails, as this one was easy to i.d., after finally adding "VCA VHS" to my searches: It's
Misty Rain!
