Chemistry 4 (2008)
剧情：
Tristan brings six porn stars to a secluded house for the weekend and lets them loose to live out their fantasies. All the sexual hook-ups are spontaneous and completely up to the performers, and they waste no time getting naked before the cameras are even ready to roll! Sex begins as a one-on-one affair until whoever has the Perv Cam joins in, and pretty soon it becomes an incredible 36 hour orgy. See what happens when Sinnamon indulges her insatiable appetite, Tyler is left alone with all three women, Penny pushes her boundaries, Evan puts on his tiger suit, Adrianna uses her feet in some unusual ways, and Johhny arrives late—and must make up for lost time.
