Feature movies are a different form of adult entertainment. DVDs come into two separate formats. There's the compilation of different, unconnected scenes that may be linked by a common thread, like Big Tit A-List. Then there's the feature, a full-length movie such as K-JUGS. This video is one of the chapters from K-JUGS, an XL Girls presentation with an all-star cast (Renee Ross, Samantha38G, Bailey Santanna, Jade Parker, Brandy Ryder and Reyna Mae).
As an editor, I'm often asked to write scripts either for scenes or for features. I went halfsies with another editor to write the script for K-JUGS. It's a take-off on the sexual hijinks at a radio station where all the women have tits that could crush your head. Some of the inspiration came from classic films in which the basic theme is that an established star is angry that a newcomer will usurp her position, leading to trouble.
Here's the background on this movie.
