Figured it was time I did another flat pic, this time involving   dangomango102 's heroines, Shimmer Fox, Miss Stallion, and Lady Delta

Seems like they run a foul of some nasty villain, who's trapped them in sheets of rubber. At first, they tried to fight it, but it became apparent these were no ordinary sheets. Each girl getting sandwiched between two of them, they quickly felt dramatic pressure on their bodies. It didn't take long for them to flatten down, in the process feeling a large amount of pleasure in their bodies, addling their minds. With a boastful villainess in the background, it seems the girls are doomed to a fate of being helplessly flat posters for many to gawk at.

Or it's just a very prank prone shop owner who needed a advertisement, and wanted the 3 in 1 package deal. Someone might've been bored, to the detriment of everyone. Luckily her assistant will sort things... eventually...
