In the empty house, the siblings' passion ignited. As they shed their clothes, anticipation built into desire. The little sister tiptoed towards her big brother, hesitant yet brave. They shared a gentle kiss, their hearts racing as their bodies melted together. The brother's hands explored her still-growing curves, his touch tender yet full of longing. The sister moaned softly, her body asking for more as she wrapped her arms around him. Their kisses deepened, their breaths synchronized. He pushed her gently onto the bed, his rough hands contrasting with his tender words of love and protection. Slowly, he entered her, filling her up with his passion. With each thrust, their connection grew stronger. The room echoed with their gasps and whispers, a symphony of love and lust. They made love like it was the last time they'd ever be alone together because they knew it might be.
