Blac Chyna held a yacht party in Miami recently, and her onboard outfit was so stunning that a photo shoot was necessary. The focus of the shoot is immediately obvious, as her fully exposed backside is looking bigger, rounder, and more powerful than ever. The most astonishing pics show the yacht's railing disappearing into the social media star's booty flesh. 

Behind Chyna flies the flag of our nation -- a land of huge portions. After the shoot, Chyna got onboard a jet ski. Her ass sat in the back of the two-man seat.
