Ass strength comparison

Bianca and Michela compare their asses and sexily show them off to the camera before engaging in a pretty unusual ass battle. They kneel and bum against bum and begin pushing with all their strength.
At some point, Bianca changes her strategy lifting her ass up in the air in order to apply even more pressure, while her tiny thong bottom barely hides her most private parts.

Facesitting for the loser

The battle continues back and forth until the moment when Bianca pushes so hard that makes Michela do a backflip, and is declared defeated.
The final reverse facesitting victory pose is another highlight of the video!
