AN: This fanfiction is off the prompt Slutforsastiel wrote for me on Instagram. So definitely go and follow them if you like all things Sam/Cas! They were the first other Sastiel shipper I ever spoke to :)

Anyway this story is a GAY relationship so if you're homophobic please just go away and don't message me or leave anon reviews. Also this will be multi chapter, but short chapters, as I have so much I want to write and there will be view changes etc but hopefully it will be done by the end of the week.

Warnings: Maybe bad language, No smut but lots of kissing

Disclaimer: I do not own Supernatural but this story IS mine.

HIGHSCHOOL AU- Well I'm basing it off a UK sixth form (4 subjects ages 16-18)

If Castiel Novak, a boy who, although a bitter, cynical git sometimes, was usually rather polite and approachable albeit Introverted, had known today would be the day that changed his life maybe he wouldn't have been so rude towards Gabriel, with obscene language, gestures and a good deal of threats, when he awoke him with a bucket of ice water after Castiel hit snooze on the alarm three times! Maybe he wouldn't have proceeded to beg Gabriel for the day off school because he was going to "Puke so hard" he'll "Create a black hole and fill it before it can swallow the earth". And maybe he would have eaten a bit more toast, and bought some breath mints.

"Okay for your homework I want you to attempt to re write a scene from your favourite book- and yes Bella, I want it in Latin- this is a Latin class." There was a collective groan but Castiel wasn't bothered, he could re write his entire favourite book, Pet Semetary- Stephen King, in his sleep. He had done it repeatedly over the years. He was fluent in Latin, his Dad had taught him from the age of 4 until he died, when Cas was 13. He was 17 now. Packing up his bag he was heading out the door when his stomach lurched and he emptied it's entire contents over the floor.

10 Minutes later Castiel was seated in the nurses office waiting for Gabriel to come and get him.'Pretty girl by Maggie Lindermann' blaring in his ears, he wouldn't be surprised if it was audible outside his head phones. 'Stupid fucking toast , that Bas-' but Castiel's train of thought stopped dead as a giant walked into the room. Okay so maybe giant wasn't the right word, a tall, broad shouldered boy with thick biceps that you couldn't get 2 hands around, and hair that Cas would just love to run his hands through. 'Wait. Where did that come from.' While Castiel had been thinking the boy had walked into the room and taken the chair opposite him. The nurses voice cut through his thoughts. "Alright Love, Your brother is on his way from London, he'll be here in about an hour."

"Thanks Miss."

"No problem Sam."

Castiel's blood ran cold, this was Sam freaking Winchester, only the most popular kid in the whole school, mostly because everyone knew his brother Dean and his Mentally ill father who had been locked up for years after claiming demons killed his wife. However even knowing this Castiel couldn't help thinking how cute Sam was. 'He would never be interested in someone like me...' Even with this though with shy eyes Cas turned to Sam.

"H...h...hi?" It came out as a stuttered question and Cas had never wanted to whack his head off a wall more. Sam turned to look at him, almost seeming to study him.

"Hey, whats up? I'm Sam." Sam held out his hand and Castiel took it. Castiel went to reply but he never got a chance as the nurse walked in.

"Your brother is here Sweet."

Stupid fucking Gabriel always ruining everything.
