So a while back I thought, what if that whole serial breastcalation thing was done with butts? By chance I saw the Nicki Minaj poses or whatever and realized there are a few pics that unintentionally lend to such progression lol.

Pinkie: "Ohhh yeah! Booty party! Shake it, shake it!" (average)
Sunset: "Nice try Pinkie. But this is what they really want. Aw yeah!" (large)
Adagio: "B-yatches, please." *mountainous cheeks clap it like thunder (X-large)

Big thanks to the artists:
Pinkie, mr-sampson
Sunset, celestial-fx
Adagio, cbatie11
(artists don't seem to be on DNP so I'm guessing this is ok for the time being)
