From the famous website.
The cruise around in a van and find some pretty girl. (Ok, she's in on the gag, a hired actress, but she pretends to be someone tricked into this.) They take her to an apartment where four black guys with big dicks (including that Diesel guy with the biggest one of all) have at her, orally, vaginally, and anally, sometimes all at once. Every girl gets anal; every girl gets DP. The girls are all pretty (and horny, and kind of stupid).
The only downside (for me) is that at the end all of the guys jack off in the girl's mouth. If they would creampie her, they'd have the greatest series in porn history, but it's all good, anyway.
