Part II appears to be a continuation (or perhaps additional footage from) Part I.  With a few exceptions, it has the same cast.  This time, a semi-plot emerges from mysterious Chinatown as two girls, clad only in sexy underwear (!) peruse the contents on an antique shop where the best bargains are found between their thighs.  The girls tend to discover their intimacy in groups of two, three, and four, and anal proves to be a very fulfilling theme when the guys and dildos are put to task.  Oriental fun with a twist.  Not bad.
