Can't blame her for looking. He ends up glancing at himself too, not really knowing the reason why, because it's going to look the way that it always does. Then he finds himself glancing up quick enough to check on her reaction.

It kind of feels to him like waiting to pass an inspection to Han. He seems to have gotten clearance by the eager return to his kiss and the suggestive nudging of her hips. He's chasing that warmth of hers and in this moment, it almost feels like she's daring him to keep up - either consciously or unconsciously.

He answers the coaxing by leaning in close. Lining up his hips with hers. Wordlessly teasing his length between her legs.
