She was rolling her hips slightly, meeting his thrusts and enjoying the feeling of her body starting to heat, blood starting to pump faster, when he showed her what he wanted. She grinned and bit her lip, focusing on the beating of her heart and setting it a little bit faster. Nothing life threatening, simply the rate of a brisk jog. It would set the blood flowing faster.
When the knife appeared beside her, she knew right away what it was for. I'm honored, Alexia. Truly. Kissing the flat end of the blade, she tried to focus even while he was drawing heady moans and gasps from her with the motion of his hips. She plotted where she wanted to strike with the tip of the blade before gently pressing the blade between two ribs on his right side. She started with a gentle sawing motion to see if she could part the skin, at which point she'd push in and up.
