This was filmed when I used to weigh 235 pounds, I am now currently 157. I clench flex my buns, Left cheek then right cheek back and forth fast!I stand and plop my big plush booty down on the seat! I stand and clench too!All Alone I think of how crushed and And covered completely by my ass, you would be if you where my seat!!
