The older sister laughs softly, her gaze lingering on the younger one's fingers as they teasingly brush against her skin. "We could always find something to keep ourselves entertained," she replies with a wicked grin. "But maybe we should save that for later." She leans in closer, her breath warm against the younger sister's ear as she whispers, "There's plenty of time for more fun tomorrow night."

The younger sister laughs softly, her fingers continuing to explore beneath the hem of her shirt as she listens to her older sibling's suggestive whispers. "Oh really?" She arches an eyebrow playfully. "And what exactly did you have in mind for tomorrow night?" Her voice drops lower, becoming more husky with desire.

As she continues to tease and flirt with her older sister, the younger one can feel herself growing increasingly aroused.
