This is from @thelittleredwhocould and I am soooo in love!
You said you had a rough day, so I wrote you a little Wincest something to maybe cheer you up?
The boys’ first time isn’t until much later in life, after they’ve both been to help and back, and decided they can do without each other. The hunt was rough- vampires, naturally- and Dean couldn’t help it. The moment the motel room door clicked shut behind them, he grabbed his brother’s head in his hands and kissed him with all the passion a lifetime of pining can muster.
Now Dean is nervous, adrenaline driven bravado gone and replaced with gentle trembling hands on his brother’s chest as he unbuttons the red flannel Sam looks so damn good in. The more perfect golden skin, dusted with just the right amount of chest hair, that’s revealed, the more nervous Dean gets. He doesn’t want to stop, though. He’s wanted this for years and now it’s happening, and he needs it to go right.
“Dean,” Sam says, hands jumping from his hips to his face. “Dean, look at me.”
Dean lifts his eyes to meet Sam’s, breath catching in his throat at what he sees there. They’ve both been through so much- more than anyone should have to endure- but Sam is here. Sam is stroking his thumbs over Dean’s cheekbones and smiling that sweet, familiar smile Dean’s been in love with since they were kids.
“I’ve got you.” Sam’s voice is as soft as his touch. “It’s okay.”
Sam leans in and kisses him softly. Dean melts against the larger man with a soft sigh. Just like that, Sam is in charge and Dean’s pretty okay with that. He’s okay when big hands strip them both bare and lay him out on the bed, and when those same hands set out to discover all the hidden secrets of his body. This is Sam, after all, and there’s no one Dean trusts more than Sam.
