Two things:

1. All the scarebroart posts are in a pretty random order, but with captions that helpfully bring groupings together, for example,

elsa_maid_skirt
elsa_yoga_ball
elsa_yoga_workout

so the e-hentai posts are sorted into caption order. This is done for each part upload spearately. (Hope this is clear)

2. The running "joke" is the sense of shock the models have with scarebroart's transformations. Hence the scared look on so many of the faces.
