Alejandro, a young American scholar, arrives at Keilimar's Brazilian home for an academic exchange. Naive to local customs, he's unaware of the 'favors' Keilimar's neighbor, a insatiable Canadian vixen, expects in return for her hospitality. Keilimar watches in disbelief as the beautiful blonde seduces Alejandro in their shared kitchen, her voluptuous curves and eager moans leaving no doubt about her intentions. The stepsister's frustration grows as the Canadian's sexual prowess wins Alejandro over, their daily trysts echoing through the house, leaving Keilimar's fantasies unfulfilled.
