Gangbang first, cream pie second.
It's actually a 28-guy cream pie. The guys butt fuck Jennifer, d.p. her, throat fuck her and dump their loads in whichever hole they choose at any time throughout the flick. Most guys pop twice - which is probably where they get the 50-count. But the number is irrelevant because this is simply one very large gangbang in which Jennifer gets piston-pumped like a fuck doll long after her body is covered in sweat and her cavities are overflowing with spunk.
By the end, those painful moans resulting from a sore pussy and ass that keeps getting pounded couldn't be more real. Yet she manages to keep going for another 20 minutes.
