Zach accepted the plastic container as if it were a little treasure. After taking off the lid, he closed his eyes to just revel in the smell for a bit. It seemed a bit sweet for his taste, but he wouldn't have to act as if he liked it. If his kind believed in the concept of 'guilty pleasures' chocolate would be his. It was one of the things he looked up whenever he was walking amongst mortals, and it had frankly sucked that he hadn't been able to do so for the entirety of this 'operation'.

He carefully carved out a chunk before lifting the fork to his mouth with something as close to reverence as he might manage. As the taste his his tongue, his eyes fell closed and he let out a low, but heartfelt moan. When the bite was finished, he immediately went back for seconds- and thirds, savouring each bite. He only played it up a little, making sure he wouldn't look like a pig, and licking the spoon and his lips to chase after crumbs. He seemed completely oblivious as he slowly worked his way through the little cake, abandoning the fork when he got to the bottom so he could scoop the last of the sticky crumbs from the bottom with his fingers. When he'd gotten the very last crumb, he lingered with his finger in his mouth, slowly drawing it out as he cleaned the last of the taste off with his eyes closed. 

When he only had the tip of his finger in he seemingly absent-mindedly opened his eyes, hoping to catch the priest's gaze. As he did, he promptly let his cheeks flush a bright red while he quickly pulled his finger out the last bit.

"Er..." he mumbled, making sure his lips would be just a bit flushed as well. "That was really good. I, er... really like chocolate," he sheepishly chuckled, blush still present on his face. 

"Did you like it as well?" He dragged his eyes away from the priest's face to peek into his container, briefly checking if he'd left any crumbs.
