Historical context is the act of
butt fucking by man into a woman for pleasure that ensures non-impregnation. The ancient practice serves to prevent pregnancy and loss of ability for a working lady to make money.
Vaginal sex = “money hole.” “Cornhole” refers to the
netherworld of penetrative sex that presents as more forbidding, dirty, and therefore desirable and that could bestow on the offerer a more generous transaction, perhaps a full larder or corn crib for the winter.
