“We all start somewhere,” is how premier pro-am fisting studio StudFist introduces its newest recruit. But somehow I have a hard time believing the masked fist bottom making his debut on their site this month – who goes by the simple moniker of ‘Boy’ – is really a beginner. For one thing, he looks far too at home in that sling, and when Amerifist puts his enormous paw into new Boy’s butt, it opens right up to meet his knuckles like a bunch of old friends.
