I'm sure the japanese have already done this, but I have a great idea for a bukkake.
Remember when you were in school and you had that one hot teacher that you would jerk off to?
Here's what I want to see in a bukkake.

Have a sexy teacher in skirt, glasses, etc. lecturing a group of students. Of course she's doing the sexy teacher thing (bending over the desk, etc.). Then all of a sudden have her say, "oooh, it's so hot in here." Then have her unbutton her shirt, take off her pants, or something. Then, have the horny group of students start jerking off and a few of them go up to her rip her clothes off and make her sit down in front of the desk. Then have them bukkake her.

Hey, the same thing can work in a prison scene with the female warden disciplining all of her male inmates.

This has been done in American Bukkake. Number 8 if my memory serves me right. Alisyn Chains, non?
