In the dim glow of Moe's Tavern, a hidden camera captures the unexpected. The ever-lustful Homer Simpson, fueled by Duff beer, can't resist the allure of his own daughter, Lisa's, innocent charm. As she innocently reads her erotic fan fiction aloud, Homer's mind races with depraved thoughts. Meanwhile, Marge, in a moment of desperation, turns to her son, Bart, for support, leading to an awkward yet arousing encounter in the Kwik-E-Mart stockroom.
