As a British MilFer we get asked quite often "what's your secret steemmies big butts". And I'll admit, its not that difficult to answer. Steemmies are just big butts. Big as in size and girth, not the size of the penis when flaccid (that comes next) or the size when erect. steemmies are not big butts, they are big butts with an average size dp when flaccid and a big dp when erect, which is why we can give the Steemie the boot..
