Book of Lust gets off to a promising start as Chelsea Blue, an American in Europe, meets four Hungarians in Budapest. The girls are model-gorgeous and the studs untiring. One girl keeps the guys busy while the other joins Blue in the tub. The sex here is pure Euro-raunch: raw, intense and uninhibited.

Blue leaves for Rome and calls her friend in L.A. after arriving to get the number of one Professor Maurizio. The author of The Book of Lust invites her over, and she watches him work with a couple on their emotions as they fuck. Dick Nasty and some Rome need little coaching in soem areas, like sex, and Blue is shocked. From this point on, the sex becomes less intense as a pretense of a plot is followed.

The European footage at the beginning is great, and between that and the opening sex, this could have been a scorcher. Too bad the momentum flags.
