It's the fourth volume of Vivid's big butt series, and they've got a measuring tape handy at the outset of every scene to prove to the camera that each one of these girls' cabooses measures up to the exacting standards of the title. And every girl measures up.

After that, it's all straightforward hardcore from the pros with a dash of face-sitting and plenty of butt-bouncing hardcore. And with a run-time of over three and a half hours, 40 Inch Plus 4 gives plenty of bang for the buck.
