Bored and alone, a brother resorts to self-pleasure, his hand working his hard cock as fantasies of his sister fill his mind. Unaware, she enters, catching him mid-act. Shock turns to lust as she watches him stroke, her own hand inching towards her dampening panties. Boldly, she asks, "Can I help with that?" Kneeling, she takes him in her mouth, her hand joining his, jacking him off until he explodes, his cum coating her eager tongue.
