Work Text:
There’s something nice about no longer pining over Casey. Something nice about getting to watch him and appreciate his body without worrying about getting caught or having to explain the horny look on his face as he watches him do … well, anything.
Today, it’s acting like a mechanic.
It’s not as if Severide doesn’t know everything Casey knows about cars and trucks. Even if Casey’s got more hands-on knowledge because his foster dad had basically made it his mission to make Casey as self-sufficient as possible, Severide also loves cars and loves knowing everything he needs to know about his / their cars. He loves cars almost as much as he loves Casey, but he loves watching Casey work on their cars more and no one gets to touch Casey’s truck (not even him!)
It's always kind of amusing to Severide that Casey treats his truck the way he does considering how old the truck is. Severide treats his car that way because it’s a new car, but he doesn’t get caring so much about a truck he’s had since he was eighteen.
But he does enjoy watching Casey take care of the truck, changing the oil, checking out the engine because it made a weird noise yesterday, and washing it every week like clockwork through the summer.
He does it shirtless, too, since his truck is always out on the street, and the sun is shining causing things to be quite hot.
Which is why Severide’s sitting on their front porch steps watching (technically the boys using water guns), but really, his someday future husband (whenever he works up the nerve to propose) take care of his truck. He’s got a fan that he’s waving in front of his face because it’s so hot but he’s largely hot under the collar just from watching his man.
Fuck, it’s so unfair that he’s so damn hot.
He hears slight laughter before he’s hit with water from the boys’ water guns and he yells in shock, but they’ve gone running down the side of the house to the backyard.
He wipes the water out of his eyes to see Casey laughing at him.
“What the fuck was that for?”
“Maybe they thought you were overheating,” he teases with a wink that tells him that he knows that Severide’s been thirsting over him all afternoon. “Maybe you should cool off by helping me wash my truck.”
“And miss the free show? I think not.”
Casey laughs and shakes his head as he grabs a bottle of water. “You’d think you’d been deprived with the way you’re acting.”
“You should get used to it, Case,” Severide retorts as he gets up to pull him close for a kiss. “Because you’re my boyfriend now,” he says as he pulls him close, and lowers his voice. “And that means I get to lust after you whenever I want.”
“Fuck,” Casey breathes, eyes dark as Severide brings their lips together.
He loves the feeling of Casey wrapping his arms around his neck, brushing their noses as they slide their lips together. He tastes a little bit like salty sweat, his lips a little rough, but before he could dive too deeply into the kiss and chasing the taste of him, he’s suddenly feeling wetness down his back and gasps.
“Shit, sorry, Sev,” Casey offers, as Severide glares at him.
This is far from the first time that Casey’s accidently dropped some sort of liquid down his back, too distracted by kisses to remember to set it down.
“Case!”
“I said I was sorry,” he offers as consolation as he lets go and Severide moves to take his shirt off. “It’s your fault for being thirsty anyway.”
“You can’t drink through your back, dad,” Ben says, appearing in the gap next to the house.
“That’s not the thirsty he meant, Ben,” Griffin interjects, making a face as if he wishes that he didn’t know what kind of thirsty Casey meant.
Ben’s eyebrows are crinkling, and Casey’s blushing.
“How do you know about that kind of thirsty?” Severide questions, despite Casey shaking his head at him. He clearly doesn’t want to know why Griffin knows that.
Griffin gives him a look of annoyance. “Obvious reasons,” and then squirts him with water, causing Casey to jump away from him and laugh.
Thankfully, Ben seems to follow Griffin’s lead and quickly soaks Casey before running away, too.
“At least I’m not the only reason you’re wet now,” Casey offers with a laugh.
Severide rolls his eyes. “Yeah, well, it’s still your fault I got wet in the first place.”
Casey grins. “To be fair, you looked like you needed to be cooled down.”
Then, before Severide could retort, he takes the rest of his water and dumps it over his head before he goes chasing after the boys.
“I hate you!” he yells, not seriously as he chases after him.
“No, you don’t,” Casey yells, as he turns into the backyard and immediately gets soaked.
Severide was so focused on catching Casey that he doesn’t realize that he’s fallen into the boys’ trap, getting soaked from above with no way to retaliate.
Thankfully, they quickly found their own water guns and even with the boys up in the treehouse, it’s a somewhat easy fight, especially when they start to trick the boys by going after each other until the boys come down to get more water.
It’s fun, it’s ridiculous, and it’s, honestly, perfect.
He loves these kinds of days.

“So, mister mechanic, how’s the truck?” Severide questions, hours later. The boys are in bed, and he and Casey are cuddling on the couch. Tired, but pleased that his future will have so many more of days like this.
Casey chuckles. “It’s getting old. I was able to fix it, but it probably won’t last much longer.”
Severide gives him a soft look. “That sucks. I know how much you love that truck.”
“Yeah, but I probably should’ve traded it in or something sooner since it only seats three, so you’ve had to do the driving so far.”
“I like driving,” he replies. “Though not as much as I enjoy watching you play mechanic.”
Casey laughs and rolls his eyes. “You just like that you can openly thirst after me now.”
“Like you’re any better when I’m working out.”
Severide’s caught Casey watching him even before they got together and hoped that it was a sign of his interest (thankfully, it was).
Casey flushes. “Yeah, well, as you said earlier, I get a free pass to lust after you now, don’t I?”
He kisses his cheek, and Severide turns to kiss him on the lips, the game they were watching, the conversation about thirsting after each other is forgotten because he’s much more interested in kissing Casey.
Casey’s obviously on board as he moves into Severide’s lap without even breaking their kiss. Severide happily finds his hands on Casey’s waist as Casey’s hands wander down his bare chest.
His lips are softer than earlier, taste a little like the chicken and rice they had for dinner mixed with beer. It’s as Severide runs his tongue over Casey’s lips, begging for more, that Casey leans back, breaking the kiss and panting a little.
“Yeah – yeah, I think… all that lusting today means we should, you know, go to bed?”
Severide grins. He knows that he’d like nothing better, and thankfully, so does Casey.
“Gladly.”
“Good.”
Lusting and thirsting aside things have been so much better since he no longer has to pine, and he wouldn’t want it any other way.
