Wow, folks have some skewed perception of dimensions!
According to IAFD, Lacey is a tiny little thing...5'2" and 90 pounds. I suppose it's possible she has some freakisly large hands for her size, but I doubt it.
The guy looks to be on the longer side of average...between 6-7 inches. But he's not very girthy...I'd guess somewhere in the 4.5 to 5 inch range.
