St. Louis Salt Lick

When you're railing a cowgirl that is at least 15 years older in a seemingly empty pasture, atop a hay bale. This is generally done in early spring before bugs are hatching out. After going at it for a while, the man feeling a tickle on his ass (thinking it is a bug, but realizing its too cold), turns around to see her Clydesdale horse licking his asshole.
