This retreat video has very little to recommend it, the most notable being the appearance of the lesbian scene featuring Andrea True, whom almost everyone knows hasn't worked in the business for nearly ten years. Her performance, however old it may be, is still sufficient to save this video from the bowels of obscurity (if you don't mix the metaphors, how can you blend them properly?)
Unfortunately, the uncredited director has seen fit to replace the entire soundtrack with new moans, probably in an attempt to disguise the original source of these segments. Some seem to be old loops, and others are probably from some nearly forgotten films of late 60's vintage. (There's even one scene where penetration obvious isn't taking place for the majority of the scene; something that couldn't be forgiven in a newer film.) This one isn't going to be at the top of your "Must See" list.
