Positive encouragement helps Han to settle in and let him know he's on the right track. It makes a part of him want to speed up and do more, faster, but he forces himself to double down on the slow and steady.

The other thing that helps is that Han's not all that shy. He doesn't seem at all uncomfortable getting to work and as he goes through his progression, he'll press his face in further. So that she can press up on his cheekbones and feel the angle of his jaw against her thighs. Even his breath seems to be working at trying to make her feel warm and good.
