A/N: Hello bunnies! So a couple of lovely people asked for a second chapter, and I was more than happy to oblige ^_^ I hope you like it! x

It was a few days after Dean had caught Castiel taking pictures of his behind that the hunter started to suspect the Angel was up to something again.

Dean had been sat trying to eat his breakfast, but it was difficult with Castiel hovering beside him. The angel's gaze kept flicking between staring at Dean with some fascination and his phone which he would rapidly type on.

"Uh...Cas?" Dean eventually said as he reluctantly put his fork down. "Do you need something?"

"Not at the moment" Castiel replied with his eyes still glued to his phone screen.

"Are you sure?" Dean countered. "I can't eat my eggs with you watching me chew so closely, man."

"Oh, it's not your jaw that I'm interested in" Castiel replied. "It's your cheeks."

"My, uh...my what?" Dean stuttered in shock. He subconsciously raised his hand and starting rubbing it across his blushing face.

"Your cheeks" Castiel repeated louder, believing Dean had just not heard him the first time.

"No, I got..."Dean trailed off and cleared his throat. "Just to be certain...you mean my face cheeks, right?"

"Yes" Castiel replied with a frown. What other kind-"

"It doesn't matter" Dean quickly interrupted.

His eyes were wide and concerned as he picked up his coffee and started to chug it without taking a breath - he really needed to put some liquor in it.

He was taken by surprise when he suddenly felt Castiel's lips press gently against the side of his face.

The hunter almost spit out his coffee and had to put the mug down before he dropped it. He gulped loudly before turning to Castiel who was already back on his phone.

"Cas, what was that?" Dean asked, still looking shocked.

"It was a kiss from an angel" Castiel replied as if it wasn't of any importance.

"Okay, but...why did you just kiss me?"

"It's another experiment that I found on the Internet which I'm trying out for science."

"Oh, really? And what's the theory behind this one?"

"Well I found several posts which claimed that freckles are actually Angel kisses, but-" he squinted as he leaned in closely to study Dean. The hunter instinctively pulled back looking slightly alarmed. "I don't think any new ones have formed."

"Cas, I've had freckles since I was a little kid, and I don't remember any angel's smooching me."

"Well your mother use to tell you they were watching over you, did she not?"

"Well, yeah, but-" The hunter grimaced slightly and shuddered. "That's just creepy, dude."

"I would be happy if no other Angel had kissed you. I don't really like the thought of that."

"Oh?" Dean said with surprise. Was that Castiel saying he would be jealous? The hunter turned slightly so Castiel couldn't see him and smiled at the thought.

"Perhaps they just take time to show" Castiel mused. "Or maybe a kiss needs to be given at certain intervals over a set period of time..."

"Maybe you should try a couple more right now?" Dean suggested.

"Alright."

Castiel leaned over and placed another kiss on Dean's cheek. He was about to do another when Dean turned his head and their lips ended up meeting instead, delicately brushing over each other.

"You moved" Castiel complained when he pulled back.

"Oops" Dean said with an innocent shrug. He smirked and got up to put his dishes in the sink.

"Results thus far are inconclusive" Castiel murmured to himself as he typed the notes on his phone. "Further data definitely needed."
