Zach is aware of every singly brush of skin, revelling in how gentle the priest is being. It was rather refreshing to be handled like a precious thing after the couple of weeks he's had. Of course he usually doesn't mind it rough, but the physical only goes so far to nourish him. While this is not even close to the kind of desire he needs from Kiel, it is nevertheless a taste of what things might be like once he manages to snare the human. 

He still pays attention to his work, of course, letting a faint blush deepen every time the priest's breath ghost over the sensitive skin of his neck. He doesn't need to fake the shiver that runs down his spine, or the heat that starts pooling in his lower stomach as he swears the priest leans in close enough to nearly brush his lips over the sensitive patch just under his ear.

If he went too far too soon, he would only sent him away 'for his own good'.

"Thanks. .. You know, for everything, not just for the shirt. You're a good man. .." he looks at the priest earnestly for a few moments, blush slowly fading, before breaking the silence with a chuckle. 

"Heh, guess I'll see if I can get some sleep now. If you ask me, it's rather stupid that things start to hurt more before they stay to hurt less, but there you have it. "
