"I can't. Not yet...not until I'm sure," he replied, beginning to speed his thrusts up, though not moving into her any harder. He was still playing this game and maybe he would keep it up for a while...maybe he wouldn't. It all depended on what she did from here on out. Stefan moved his free hand up to her face, running his fingers along her full lips slowly. "Suck," he commanded, pushing a bit with the digits to get her to take them in. He always did prefer when she was quiet during sex, as much as he did love her begging.
