I know "love" scenes are hard to write, but this metaphor really isn't a good one
„He watched pleasure turn her eyes to blue crystals, tasted her moan as he crushed his mouth to hers.“
Nora Roberts, Savor the Moment.
Please tell me what is so sexy about crystals for eyes, even if they are blue? They are cold and hard and while they are pretty to look at, they are hardly sexy. That is an image that belongs more in a horror story than a romance novel."The Girl With the Crystal Eyes", anyone?
