Prompt from annamatopia!
Sam and Castiel get into some sort of trouble and it's Dean who has to bail them out. Au with Dean being 20 and Sam and Castiel being 16. Castiel is living with Sam since his parents kicked him out of his house since he's gay. :(
Sam was not anticipating Dean to come get him at school. It was afterschool, and mostly anyone had left. As he sat outside the main office, he could hear the principal as she talked to his older brother. He could practically hear Dean's teasing when he got here. He started to fiddle with the hem of his shirt, a nervous habit he had picked up. As he closed his eyes, another set of hands gently pulled his hands into their lap. He opened his eyes to be faced with a pair of blue eyes, ones that he had fallen in love with.
"Sam, don't worry. Dean wouldn't be mad. I hope." Mumbled Castiel as he rested his forehead with Sam's. Cas felt Sam relax under his touch, and cupped Sam's face and pulled him into a tender kiss.
Sam placed his hand on the back of Castiel's head, not to deepen the kiss, just to feel Castiel's hair. He felt Castiel's tongue swipe his bottom lip and he opened his mouth, but closed it before Cas could stick his tongue in.
"Cas wait." Said Sam, pulling away from Castiel's lips. But Castiel was having none of this. They interrupted before they could finish what they started and Castiel was planning on having Sam here and now. He straddled himself on Sam's legs and started to grid into Sam, earning a moan from him.
Cas started to lick and bite at Sam's neck, leading towards his ear. "Can't wait Sam, I need you here right now." He huskily said, thrusting his hips into Sam's crotch to emphasize his point. Sam could feel the outline of Castiel's dick on his jeans and he lost it. He wrapped Castiel's legs around his waist and pulled him swallowed Castiel's moan with his mouth, and shoved his tongue into Castiel's mouth. He then slammed Cas into the wall. Their tongues battled for dominance as Cas traced Sam's abs with his fingers.
Sam was going to take Cas here and didn't care who watched. Cas seemed to have the same idea as he slid his hands into Sam's pants, pulling at Sam's dick. He pulled Sam's jeans down, only leaving his boxers. Cas started to lick at Sam's covered dick, knowing that the more he teased, the harder Sam would fuck him. The noises that Sam was producing were enough to make Cas come..
"Fuck Cas, stop being such a freaking tease and suck my cock" growled Sam. Just as Castiel was going to take Sam's cock into his mouth, they heard the sound of a cup shattering on the floor. Sam turned his head to find the Principal with her mouth open and all color drain out of her face, and his brother who was bright red.
Sam groaned and hit his head at the wall. Castiel quickly stood open and helped Sam put his pants back on before facing the adults.
"Well this is awkward", whispered Castiel to Sam.
Sam couldn't help but chuckle a little. " No shit Sherlock" responded Sam, as he took Castiel's hand with his own.
Castiel looked down at their hands and back at Sam. He's lips were swollen from the kissing and his hair was all messed up. His face was red and he was panting a little. His brown eyes were filled with love, which made Castiel's heart jump a little.
I love you" said Cas quietly, which only Sam could hear. The smile that Cas received could of lighten the whole room.
"I love you too" replied Sam, leaning to get a kiss, but interrupted yet again by the principal blabbering. Sam ignored her and kissed Cas. The kiss was tender and sweet, by definition one of their best kisses yet.
