It's interesting that a lot of mainstream takes on wam are strictly "neck-down", whereas "genuine" wammers will usually consider the face and head to be the primary target. Not a criticism of the find by the way, just an observation.
The full video is actually pretty impressive. The mistress doing it is awesome, and she does really trash the models she is working with. It isn't only neck down - the second model gets pretty well trashed completely (even though the preview doesn't show it), but the mistress does focus more on the body overall.
