A lot of people complain about the lack of story in adult videos. Just shove this one in their faces and they'll shut up forever. This feature has more story than three Dashiell Hammetts. As continued from Part 3, Aja and Jerry Butler believe that they are reincarnations of ancient beings; Saki is some sort of spirit from another dimension; Taylor Wane is a shape-shifter who is usually a cat in Jerry's lap; Alicyn Sterling has been sent from the future to protect Aja's unborn baby from Taylor, and Steve Drake is a houseman who may be up to no good. It would take about five viewings of this show, along with Part 3, to get it all straight, but I don't think that it's that important. When the story gets this confusing, thankfully the sex maintains high levels of eroticism.
Aja and Jerry Butler's opener is easily equal to their one-on-one in Part 3; Wayne Summers and the since-departed lovely Alicyn Sterling are red=hot in another duo; always sexy Taylor Wane, Steve Drake and Aja do a superior threesome. The Saki/Aja bout from Part 3 has been expanded to include various unbilled ladies, all in whiteface and geisha wigs. I spotted Shawnee Cates and Leanna Foxxx in this very unusual scene.
There are two drawbacks to this other wise well-done show. The box advertises a scene shot in Thailand, and there is indeed a scene with some real Orientals that has nothing to do with anything else. The only trouble is, while they say nothing, the director's decidedly Occidental voice is heard, occidentally. Also, unless the error has been corrected by now, the opening credits tell you that this is Part 2, not 4 -- so don't run out and return it. Keep watching, and if the cast credits match those listed here, you've got the right one. Stock the whole series for maximum results.
