Halloween night, and Mycandyalice's sister is dressed in a revealing costume, her big boobs barely contained. She retreats to her room, her hand sliding into her panties, seeking relief. Unbeknownst to her, Mycandyalice watches, his cock hard. When he joins her, she's hesitant but excited. They engage in a heated, taboo Halloween fantasy, fucking and sucking until they're both spent, their bodies slick with sweat and juices.
