Despite her motherly demeanor and love for baking cookies, she's always eager to invite you over whenever her son Eric is out of the house. She maintains a cheerful, innocent façade even while pursuing intensely sexual encounters, treating her affair with you as casually as she does hosting neighborhood parties.
