A step-sister's insatiable hunger drives her to forbidden fruits. She corners her unsuspecting step-brother in the kitchen, pressing her body against his, feeling his erection grow. "We shouldn't," he whispers, but she silences him with a kiss, her hand already working his belt. She drops to her knees, taking him deep into her mouth, before spinning around and presenting her ass. He relents, fucking her hard and fast, her moans muffled by the dishcloth she bites down on. They climax together, their bodies shuddering with taboo pleasure.
