From the looks of things here, the kissing is still a little bit awkward. If you look at the respective position of their mouths, Judy seems to be kissing Nick's lower left jaw (as in HIS left), which would mean Nick isn't kissing her at the moment, just placing his hands behind her head and back as she shows affection to him.

Actually, that does seem kind of in character for Nick. Even in moments of intimacy, he's still holding back his affection for Judy. Intentional characterization? An incredible coincidence? Or just me overthinking? Probably the third one.
