Help! Looking for a retro movie (but not the one in the photo)

I’m looking for a retro porn movie maybe from the 80’s, which I’m sure stars Tom Byron, Joey Silvera and Amber Lynn. In one scene Tom Byron and Joey Silvera have a threesome with a blonde in a blue dress (not Ginger Lynn) who pays them to fuck her while her husband “alfonz” watches. Ginger Lynn appears later in the movie where she’s doing coke in the toilet then fucks the man.
