Great I tried it with a girlfriend and she loved it too

but she is to shy to make videos.

Maybe I can persuade her to it sometime

I never give up. My girlfriend weights 330 lbs and is only 5'2 height. And her ass have a lot of pressure like yours. She is thinking about squashing a skinny girl. She tried it with her 100 lbs girl friend

it looked so amazing. But they didn't tried the butt drop thing, it is too afraid the skinny girl. But the sitting thing was great and the skinny girls chest always compressed to a pancake.
Go out on a party and induce a skinny girl

to squashing it is so much fun!
