When a woman is giving oral pleasure to a man, and commences to gag, but still makes the man deliver a load with a handjob, whilst gagging.
My buddies girlfriend was boasting the other night about how she gave him a Duke Sandwich. I informed her that I hadn't the slightest idea of what she spoke of, and in turn, she performed the most insatiable Duke Sanwich any man has ever come to know, on me.
