It takes a special kind of porn star to make a decent bukkake. The best bukkakes are of girls who actually really really love cum. You seem to know how to find those kind of girls.

The only suggestion I have will take a little more time or money on the production. Imagine a realistic set of a movie
red carpet movie premier. A limosine pulls up and out steps a beautiful actress in her designer dress. She is instantly surrounded by the media, paparazzi, and fans. She takes interviews, poses for the camera, and signs autographs. But the crowd wants more. Her shoulder strap accidently breaks revealing her tits. At first she is embarrased but she cant resist all of the extra attention it brings. Before long she is flashing everone. She starts to take requests from the crowd. "Show us your pussy!". One of her fans asks "can I cum on your face?". Before long she is on her knees on the red carpet and everyone is shooting jizz on her face. The paparazzi is in heaven and the media is full of questions. Her designer dress is now stained with cum and her face is fully covered.
She is a star!

Another idea you should do is some kind of spin on that show fear factor. The female contestant is told she has to swallow countless loads of jizz in order to qualify for the next round. She takes every load so she and her husband advance to the next round.
