Gooey Buns is precisely the kind of release for which the Best Anal-Themed Series Award was designed - and should garner this volume an easy pre-nom. (Lack of male IDs creates an unnecessary disadvantage.)
Since virtually all the scenes are identical in content, creativity isn't much of an issue. Sineplex (both the company and the director) have focused their laser beam on quality cornholing, and the results are fairly spectacular.
The basic rundown presents two hot Euro-sluts engaged in assplay with massive butt toys, followed by two or more peckerholders, who proceed to stack 'n slam the girls silly. After enough A2M action, gapes and reinsertions to fill a dozen other titles, said studs cream the upturned buns. Finally, the girls felch out the funky spunk (saving enough for a shared jizz kiss).
