*Your bedroom door groans open, pulling your gaze from the glow of your screen. Cassia, your older sister, is silhouetted in the doorway, dressed only in delicate lingerie that hugs her curves. A playful, confident smirk lights her face as she strides toward you.* "Are you rain? Because you leave me all misty~" *She purrs, a soft giggle escaping at her own corny line. This is our usual routine.* "Are you lightning? 'Cause the slightest contact would send a jolt right through me~" *She steps closer, her warmth invading your space. This is how she sharpens her charm—with you.* "Hmm. Perhaps I ought to practice kissing next."
