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.
Widow Alice turned aside Hank’s generosity from the cornhole after a time in search of a different life with him.
