Subtlety
A woman in a pretty knee length dress is seated at a cafe. As she perches on her chair, her dress rides just a bit higher than expected up her tender thigh. Her hair and makeup are understated, as is her pretty frock. Attractive in a quiet way, she is not gilded in flashy glamour.
And she just oozes sexuality.
I watch her, and can tell that she knows exactly what she is doing.
And I find myself lusting after her. Drawn to her sexuality, at once subtle and smoldering.
