The family gathering ends abruptly as the brother-in-law's wife leaves early, leaving him alone with his irresistible sister-in-law. They dance around each other, the tension palpable. She catches him watching her, he can't hide his bulge. "You shouldn't look at me like that," she whispers, but her body language screams 'yes'. He corners her, his hands roaming her curves, her lips parting for his kiss. She moans, "Fuck me, brother-in-law. Make me your dirty little secret."
