Sorry this took so long to upload; it's that time of the academic year where we have a test pretty much every day! This chapter took me quite a while to write, as I got writers block about halfway through, but I was determinedto finish it.

Thankyou to anyone who reviewed/ favourited/ followed. It's all very much appreciated.

Anyway, here is chapter 3!

CASTIEL POV

Castiel sat in the library, absentmindedly scratching his nose with his quill as he read his book, leaving a splotch of ink on his flawless, pale skin. He was early for everything, and his study session with the famous Dean Winchester was no exception. He still had another fifteen minutes until Dean was due to show up, and Castiel suspected that he would be a few minutes late anyway.

He vaguely acknowledged students walking past him, their arms piled high with books and scrolls, chatting with each other. Cas looked up with annoyance when one of them bumped into him from behind, and was about to mutter a sarcastic remark when his gaze fell upon the blonde hair, tanned skin and green eyes of Dean Winchester. Castiel was mildly surprised that Dean had showed up anyway, let alone ten minutes early. What was more surprising was the fact that he was alone; Dean was hardly ever seen out of lessons without a pretty, simpering girl hanging off of his arm, gazing up adoringly at him.

"Hey man, wasn't expecting you to be here yet." he said, throwing himself down in the seat next to Castiel and pulling his ink and scroll out of him bag.

"I'm always early," he muttered "I wasn't expecting you to be here yet either."

Dean shrugged, and pulled a vial of yesterday's potion out of his backpack.

"So where do we start?" he asked, sounding bored already.

"Well I thought we could start with a description of what the potion does." Castiel began, and pulled the roll of parchment towards him.

Dean held the vial up in front of his face and twirled it, watching the pure black liquid inside swirl around. Cas smiled and began writing the description of what the Draught did, concentrating on the beautiful boy beside him rather than the essay

There was only one person Cas had told of his sexuality, and that had been his older brother Gabriel. Gabriel had been surprised at first, but had been supportive and accepting, and Cas loved him for it.

Although he could never tell any of his brothers this, Gabriel was his favourite. He loved all of his other brothers, yes, but none of them really understood him as well as Gabe. Samandriel was the youngest, only in his first year, and he had been placed into Ravenclaw with Sam; Balthasar was next, in his third year, and then it was Castiel in fifth. Gabriel was the oldest brother at Hogwarts, in his sixth year, although the twins Michael and Lucifer were 19 and were currently travelling the world studying dragons.

Why had Cas been forced to partner with someone as distractingly good looking as Dean? He internally sighed, unsure as to whether it was a good thing or not. Sure, it wasn't every day you were partnered with a guy that looked as though he could be a male model. But it also was dangerous; what if Dean suspected something, and then spread the word throughout the school? Cas had tried very hard over the years to keep up his image, and if everyone suddenly knew of his sexuality he knew he would be picked on mercilessly.

"CASTIEL!" he heard Dean yelling, bringing him out of his reverie with a shock.

"Huh?" he mumbled, confused.

"Dude, I've been shouting you for, like, five minutes." He said, sounding amused and exasperated at the same time.

"Sorry, daydreaming." About you.. he nearly added, before hastily stopping and mentally kicking himself.

"About what?" Dean enquired good naturedly, sounding genuinely interested.

"Oh, um, nothing much. Just about, um, unicorns. Yeah, unicorns and there.. medicinal uses."

Dean looked at him with a quizzical expression in his face. Damnit, Cas thought, why am I making such a godamn idiot of myself?

"Okay, man. Whatever." Replied Dean, still sounding slightly amused.

"So," he continued "What are we writing now?"

"Well, we could write about the ingredients now." Said Cas, pushing the parchment towards Dean.

Dean nodded and began writing slowly. Cas was amused to notice that when Dean concentrated, his tongue slightly stuck out of the side of his mouth.

He watched as Dean wrote, and was embarrassed when Dean looked up and saw him staring. Dean just smiled and continued writing.

"You're staring at me, Castiel." He said, with a slightly knowing tone to his voice.

"I wasn't! I was just, um, reading what you were writing over your shoulder!" He lied "And call me Cas by the way. All my friends do."

Dean smiled, as though the idea of being considered a friend pleased him.

"Okay, Cas." He stated, trying out the nickname.

He went back to his work, and Cas went back to his staring.

Two hours later, Castiel stretched and yawned.

"I think we're about done now Dean. I'm going to go back to my common room" He said sleepily.

"Okay. I'll walk you there" Dean replied, sending a flutter through Cas' chest.

They packed their bags and began walking. Madam Pince glared at them as they spoke, and hissed at them to be quiet.

Dean just smirked and began speaking louder as they walked out of the library, side by side. As they walked, they're hands brushed together for a second, and Cas felt a flush in his cheeks that had nothing to do with the cold winter air blowing through the draughty castle corridors. Dean seemed to have had the same reaction, as when Cas looked over, he had an adorable red blush in his cheeks.

Before long they reached the Ravenclaw common room, and Cas turned to say goodnight.

"You know," he began "I shouldn't even be showing you the entrance to my common room."

"Ah, I know you couldn't resist my chivalry. No mere mortal can withstand my charms."

Castiel smiled and turned towards the wooden door of the Ravenclaw rooms.

"Goodnight, Dean." He muttered.

"Cas, wait." Said Dean, as he grabbed Cas' wrist. Cas slowly turned around and looked into Deans slightly uncomfortable face.

"You've got some ink on your face..." he trailed off uncertainly, as he reached over and rubbed his thumb over Castiel's cheek. He felt his skin prickle as though with electricity as Dean touched his skin.

Dean stopped and brought his hand back down to his side. He had a strange look on his face; it seemed to be a mixture of anticipation, fear, and what Cas could have sworn was lust.

But that was impossible; Dean was straighter than the straightest guy on Earth (Cas' brain was too scrambled to be thinking of similes). Could Dean be gay? No. Cas' brain stopped there. There was no point in wanting things that would never happen.

"Well, goodni-"

Cas was cut off midsentence by Dean pressing his lips against Castiel's. Cas was too shocked to react, and just stood there. What the hell was Dean Winchester doing kissing him? Suddenly he decided he didn't care, and started kissing him back.

He felt Dean push him against the door of the common room, and melted into the kiss, enjoying the sweet taste of Dean's lips. He reached up and ran his hands through Dean's thick brown hair, and felt Dean's strong hands around his waist.

Dean suddenly pulled away, breathing heavily, and stared at Cas with wide eyes. His lips looked slightly bruised and his hair was even more ruffled than usual.

"I…I'm so sorry." He stammered, and backed away.

"Dean.." Cas began, but Dean was already running away.

Cas fell back against the door, breathing heavily, and watched as Dean ran around the corner of the corridor and disappeared.
