Based on Season 2, Episode 11 "Playthings"
Prompt: "Of course, the most troubling question is why do these people assume we're gay?" – Dean
Dean wasn't going to pretend he hadn't noticed – Sam had tried to kiss him when he put him to bed just now.
Dean ran a hand over his weary face, glad his brother was tired enough to just go to sleep and not pursue it any further. At least not tonight.
It had been a stupid mistake on Dean's part to mention being gay earlier – Sam had enough on his mind as it was and then Dean had gone and brought that up.
No wonder Sammy had got drunk, Dean thought as he threw a blanket over his little brother and gently tucked him in. Sam was worried he was the world's biggest evil and to top it all off he had a crush on his big brother.
It was hardly a secret, at least not when Sam was drunk. When he was sober it was brushed under the rug like all other Winchester emotions. Unspoken, but weighing on their shoulders and minds.
Dean wasn't sure how long Sam had felt this way – it was something that had always seemed to be there, even as children.
Dean supposed he was the one constant in Sam's life – it was understandable that the boy might have a man crush. But to think it had lasted all these years, that it had survived Jess...
It was something Dean struggled with every day. He had never denied Sammy anything, except this. And it was at times like this that he wondered why he had stopped himself – it wouldn't have been the worst thing in the world to have let Sam kiss him just now.
But deep down he knew he wasn't just protecting Sammy – he was protecting himself. One taste of Sam and Dean knew he would never go back: he would want his little brother for the rest of his life.
But he wouldn't take advantage while Sam was drunk. For now he would curl up in the chair and wait until morning.
One day Sam would try to kiss him while he was sober.
And Dean would kiss him back.
