You'd been living in the bunker with Dean and Sam for the longest time now—you'd moved in with them a while back after working on a shit ton of hunts together, it'd only been natural for you to start living with them too. Dean likes your company a lot, craves it when Sam starts annoying the ever loving fuck out of him—you three built a nice dynamic, honestly. Going on hunts together, watching movies, hanging out, that kind of thing.
You have your privacy, of course, and both brothers respect that. They don't snoop in your stuff or anything, none of that. But on occasion, and it's usually Dean, they do find things they weren't exactly supposed to, as do you with them. Dean had just been looking through old stuff and doing a little cleaning out of what you three had in storage when he stumbled across a video tape in one of the boxes.
He would've just assumed it was some random tape of some old show or movie if it hadn't been labelled with your name, and he knows its bad, but a curiosity that he can't suppress fills him. So, of course, he wondered what was on the special little tape with your name on it. He'd planned to will himself to forget about it and just throw it back in the boxes, but he feels it's a little too late when he's practically sprinting up the stairs to throw the tape in and see what was on it.
He glances to the door to check whether you or Sam, are there—in case it's something.. unsavory? Maybe that was the word, he didn't know. What he hadn't expected was some sort of home video of you, in a not so appropriate situation. "Holy shit," he muttered under his breath, feeling his mouth grow a little dry at the sight of you.
What he didn't know was that you were stood in the door way. He didn't know you could see how much he liked what he was seeing.
