Sorry for the hiatus guys; I honestly don't have a good excuse, other than forgetfulness and writers block. However, I overcame this block, and I present to you chapter four of Amortentia.
Thanks to anyone who has followed/ favourited/reviewed - it's all very much appreciated!
Anyway, enjoy chapter four :3

Dean could feel his heart slamming in his chest and his ragged breath as he ran as fast as he could away from the boy that he had just kissed. He didn't look back at Castiel, even though he could hear him calling his name; he couldn't bare to see the betrayed and disgusted expression that must be on the blue eyed boys face.
He was so confused. Why the fuck had he just done that? Castiel was a BOY goddamnit, and Dean had promised himself to keep his homosexuality a secret. And Cas wasn't gay.

Dean knew that he had just completely screwed up; not only had he ruined any chance of a friendship with Cas, he had run off like an idiot and just left Cas standing there, not even meeting his eyes.
He charged round the corner, and almost collided with none other than Sammy, whose face was barely visible over the huge pile of books he was carrying. Under normal circumstances he would have laughed and called him a nerd. But these weren't normal circumstances.
"Hey Dean." Sammy greeted his older brother, looking at his flustered and confused older brother, and placing the pile of books on to the hard stone floor "What's wrong?"
"Huh? Oh, nothing.." he muttered, starting to walk off slowly.
"DEAN," said Sammy sternly, making Dean turn around, the bewildered expression still on his face.
"What happened?" Sammy continued slowly.
"I just... no, I'm not talking to YOU about it. Goodnight Sammy." replied Dean, turning and beginning to walk away again.
Sam rolled his eyes and sighed irritably.
"Who did you kiss, Dean?" he asked, a bored tone to his voice.
Dean stopped dead, and once again turned to face his eleven year old brother.
"How the hell did you know?" he asked, incredulous.
Sam rolled his eyes again, because he was a sassy son-of-a-bitch.
"Your hair is all mussed up, your lips are bruised, your shirt is wrinkled and just the expression on your face."
"Okay Sherlock freaking Holmes, you just mind your own business." Dean glared at the younger boy in front of him.
"You know I'll just work out who it was anyway if you don't tell me." Sammy continued, earning himself another glare from his older brother "They're obviously in Ravenclaw seeing as the Ravenclaw dorms are right around this corner. It's probably someone you spent the entire evening with 'cause I'm guessing you walked them back to their dorms. Although, the only person I saw you with tonight was that Castiel kid in the library." Sam chuckled to himself at this - he knew that his older brother was straight as a pin. His chuckle stopped abruptly when he saw Dean look down at the stone floor, a red tinge creeping up his cheeks.
"It was him, wasn't it? It was Castiel!" Sammy breathed, amazed.
Deans increasing blush was all the answer he needed.
"You tell NO ONE! Understand?" Dean demanded, suddenly panicking.
"Of course I won't." Sammy frowned.
"That means dad, too."
"But - "
"No, Sammy. No buts. Or I WILL use a memory charm on you, okay?"
Sammy grumbled something unintelligible, and Dean, satisfied, turned away for the third time and walked off, just as confused as before, and in a slightly worse mood.

CASTIEL POV

Castiel was at in the comfiest armchair by the fire in the Ravenclaw common room. His lips still tingled, and his whole body felt numb.
He had no idea whether what had just happened was a dream or real (he was opting towards the former).
Dean Winchester had just kissed him. DEAN had kissed HIM. Dean that always was flirting with some pretty girl, who was straighter than, well, a straight thing (Cas' brain was too scrambled to think of a satisfactory simile).
Was this some kind of cruel prank? Had someone found out about Cas' sexuality? No, Dean wouldn't do that. Although, Cas had only known him for, like, four days.
No. He pushed that horrible idea to the back of his mind.
He heard the door to the common room open, and turned to see if it was Ellen Harvelle, one of the very few friends Cas had made since moving to Hogwarts from Durmstrang, but was mildly surprised to see the youngest Winchester (Cas was sure his name was Sam) striding through the door. What surprised him more was the knowing smirk that Sam threw in the direction of the dark haired boy.

Dean was lying on his bed in the Gryffindor common room, deep in thought.
What had Cas thought about it? Did he hate Dean now? Was he going to tell everyone that Dean was gay?
No, Cas wouldn't do that to Dean, he was sure. He was too nice for that.
Shit. He had spent so long covering up his homosexuality, by dating girls, flirting with them, and even kissing some of them, even though he had had no desire at all to do so.
And now Cas knew.
He would go and apologise to him tomorrow, Dean decided, and beg him to keep it to himself.
Dean shuddered to think what would happen if the whole of Hogwarts knew. He had seen the kind of bullying Justin Finch-Fletchly had endured. No. It wasn't worth it; he had decided long ago to keep his homosexuality a secret. And what would John say? He probably wanted Grandkids and a daughter-in-law and a whole massive family. Would he be disappointed in Dean for not being able to give him that? But what if Cas was gay too? True, he had never seen Cas looking at girls, and he hadn't mentioned any to Dean, but that didn't necessarily mean that he was gay, and Dean hadn't really known him for very long at all. Dean recalled the kiss, and remembered the way that after a few seconds, Cas had kissed him back. Maybe. Just maybe...
