A surprise thumb in the butt when doggy style.
So, have a lady from behind and when all is going well, put your thumb in your mouth (for a little lubrication...and make a popping sound) then GENTly rub the anus and insert thumb. Make sure the rest of the fingers are posted up top of the ass like a bowling ball. They love it!
