Dean and Castiel were sitting face to face on Dean's bed, absorbed in an intense game of chess. Sam was only half-listening to them teasing each other, while trying to write an assignment that was due the next day.
"Checkmate!" Dean yelled so suddenly that Sam accidentally dropped his pen.
"How did you do that?!" Cas asked with resignation.
"I'm just really good" Dean replied with a self-satisfied smirk. "That's three times in a row, buddy."
"Well, then I suppose that's enough for today…" said Castiel.
"Thank God" Sam muttered under his breath. Dean shot an angry look at him, and then turned back to Cas.
"Come on, just one more?" he did the puppy dog eyes. Castiel hesitated for a moment, then sighed and said "Okay… But I'm really not enjoying this. You always win, it's not fair."
"Maybe if you were better…" Dean mocked, but when he saw Cas' expression he tried to soften the blow by adding "Don't worry, when I first started playing chess, Sammy always beat me. Practice makes perfect."
"I would still beat you" Sam remarked absent-mindedly.
"Shut up" came the response, complemented with a pillow thrown in his general direction.
Dean and Cas put the pieces back up on the board and began another round. After twenty minutes or so, the game was over. Sam was just finishing his assignment, when he heard Cas exclaim "I won!"
"Yeah, you did. See? I told you you'd win eventually" Dean gave Cas a pat on the back.
"Wait, you didn't let me win, did you?" Cas asked suspiciously, furrowing his brows.
"Now why would I do that?" Dean replied, but he wasn't very good at lying; he averted his eyes, focusing on collecting all the chess pieces and putting them away, but his goofy smile gave him away. When he finally looked up at Cas, he found himself momentarily lost in the blue eyes. Cas mumbled a quiet "Thanks".
Sam was eyeing them suspiciously, and then, without a word, he stood up, walked out the door and locked it behind him. Then he yelled "SEVEN MINUTES IN HEAVEN!" and strolled into the kitchen.
Dean and Cas looked at each other in confusion. After a few seconds, recognition and embarrassment hit Dean, while Cas was still perplexed.
"SAM, THIS IS CHILDISH, OPEN THE DOOR!" Dean yelled, but he knew Sam would not budge.
"What… is going on?" Cas asked hesitantly.
"What do you…?" Dean started, then it hit him. "You don't know what 'seven minutes in heaven' is, do you?" He laughed awkwardly, heavily blushing.
"No. What is it?" Cas inquired curiously.
"It's this stupid game middle-schoolers play at slumber parties. Two people get locked in a room for seven minutes and they can do whatever they want…" he hesitated before continuing. "But in general people are expected to… expected to kiss" he blushed even more.
"Oh?" was all Cas could say. He could sense that Dean was feeling uncomfortable, which made him uncomfortable too.
"Don't worry, it will be over soon" Dean tried to sound calm, but his heart was racing.
After a few moments, the tension was palpable. The two boys didn't move away from each other, but they were avoiding eye contact. Dean was softly humming to ease the pressure.
"Dean?" Cas said tentatively after a while. Dean looked up, and their eyes locked.
"Yeah?" Dean replied, once again lost in Cas' deep blue eyes.
"Do you think, maybe, we could…?" he didn't quite know how to phrase it, but the longing in his eyes was obvious and Dean knew exactly what he meant.
He took a glance at Cas' lips, and then, gently pulling him closer by the collar of his shirt, kissed him. Cas eagerly returned the kiss. His hands quickly found Dean's face and then slid into his hair.
Way too soon, they heard the lock turn, and they managed to pull away just as Sam was opening the door. They tried to look as nonchalant as possible, but Dean's dishevelled hair and their slight panting gave them away.
"So, didya do it?" Sam asked smugly, raising his eyebrows, giving them the benefit of the doubt.
"Shut up, Sammy!"
