Compilation porn movies are adult movies with a series of "scenes" collected and presented together. Kind of like the plays of the week on a sports show. No need to worry about plot lines for the simple fact that in compilation movies there are none, just solid sex. Many compilation movies are centered around a particular porn star, specific sexual act, or type of starlet. If you know what you like and want to avoid plot and dialog, compilation porn movies provide a lot of bang (no pun intended) for your buck and will keep you busy for hours at a time.
