The could name the video "Two girls and a cuppa heart attack grill"!I'm sure there's gross videos demonstrating it, but have no willpower to check it myself.
But for super fat people who can barely move and have a body that is so thick it makes a person's agility akin to a turtle.
I can't see how a fat person can move, reach and effectively wipe their asshole which is sandwiched between two cheeks the size of beanbag chairs.
