The biggest problem with this story is that it begins developing a plot, as two guys and one's porn star girlfriend meet on a boat as they are headed to an island to work at an archialogical dig. The plot is thickened as an evil ancient art dealer enters the scene trying to convince through threats that they should sell their findings to him. All the while sexual tension is building between the two guys and the porn star girlfriend, which eventually does climax to a threesome atop a mountain overlooking the ocean. But then we are really left hanging as the story abruptly stops after an ancient orgy, and the plot is left unresolved.
All the sex scenes end with the money shot, which feels a little uncreative as you watch the third, fourth, fifth scene end the same. The movie as a whole is basically directed to arrouse men, which it probably does successfully, but could leave women wanting. I was unconvinced that any of the women in the movie even had an orgasm, which is a bit one-sided, and unsatisfying to the female viewer.
Because of the plot issues and the less than creative directing, I only give this movie a 2. I recommend it for guys, but if you are looking to arrouse a woman, keep looking.
