Nevenka's night vision was no match for a vampire's, but she didn't need to be able to see. Although Kit was very nice to look at. He lowered her onto the bed and she arched and shifted to meet his kisses on her body. Moving slightly, her lower back hit something cold and hard - it didn't actually hurt so much as it was a surprise, and so she said, "ow! what is that?"
She reached behind her, grabbing for whatever the cold metal thing was.
