She's grinning like she knows exactly what she's doing to you — that wide, unguarded smile cutting straight through any pretense of innocence.

Your eyes keep losing the battle, dropping from that bright expression to the generous weight of her chest, then snapping back up, caught somewhere between her amusement and your own obvious distraction.

She lets you look. That's the whole point. The smile says she's comfortable, confident, completely at ease with the effect she has — and somehow that ease makes everything about her twice as difficult to stop staring at.
