Summary:

Kinktober 2021, Day 2: Incest & Spanking

Sam and Dean Winchester have always been a bit odd for a pair of siblings. Sam, for his usually calm demeanour, has the habit to get into trouble on purpose to rile Dean up. And the punishment Dean chooses to teach his little brother a lesson it's, let's just say, a bit unconventional.

Work Text:

Sam had been Dean’s responsibility for as long as he could remember. And he was fine with it really. As a baby, Sam hadn’t been a fussy kid at all. He was quiet and observant, and he always had a cute smile ready for Dean, who he adored. When he started growing up, and began crawling, Dean was worried that he would start making trouble, but that wasn’t the case. Sam was a curious kid, but as soon as Dean told him to stop and stay, he would freeze on site and look up at him with wide pleading eyes, waiting. Dean loved Sam very much, because Sam was so little and yet so clever, and because when he was looking at him like that, Dean almost felt like he was the most important person in the world. For Sam, at least. He was glad that his father wasn’t around much, because he was afraid to share the attention from that little bundle of sunshine with anyone. Sam was his. 

It was no surprise that Sam’s first word had been Dean. John had been disappointed, but Dean was so proud and happy that he thought that his heart had grown twice in size. Sam was everything, and even though he had to stay behind to take care of him and couldn’t go on hunts with his dad, he didn’t really care that much. He was worried about his father, but the thought of having someone else taking care of his Sammy made his tummy feel weird, and his mood turn sour. No, Sam was his to take care of, and he was the best big brother and so good at it too!

Sammy started talking more and more not even a month after saying Dean’s name for the first time. John said that it was normal, but Dean knew that his brother was actually a genius, there was no way that babies did the things that Sam could do. He just got up and started walking around like it was nothing! It didn’t really come as a shock for Dean, because he was sure that there was nothing impossible for Sammy. He didn’t make sentences so much as he named the things he wanted or tried to make him look at. He pointed at anything and everything, always so interested in things around him, and babbled in that tiny sweet voice about whatever came to his mind. So far, food and books were the things that he seemed more interested in. Oh, and he really hated clowns for some reason. Dean found that absolutely hilarious. Well, everything about Sam was funny and lovely, because he was the most perfect kid in the world.

Until he reached puberty, that is. Then, his nightmare started.

First of all, Sam started talking bitchy to their father. He was always complaining about travelling around so much, about having to help in the hunts (or for being left behind for research other times), about not being able to stick long enough at one school to make friends. It seemed like he was unhappy about everything, and Dean didn’t remember the last time he was able to see the beautiful dimples in his brother’s face. Even though Sam was still sweet with Dean, he was easily irritable even when it was just the two of them, and his smile never reached his eyes anymore. That annoyed Dean more than anything. 

Or that’s what he thought, until one day Sam came back from school stating that he was gay and that he had started going out with a senior from his school. Just like that. What was Sammy thinking? There was no way he was ready to date anyone, much less an older GUY, a guy that Dean didn’t even know because he had been ditching school since the start of the year. That was gonna change NOW, obviously, and he was so gonna ground Sam for being stupid. 

-No, Sam, you won’t go out with anyone, and much less with someone older than you.

-I wasn’t asking for your permission, Dean.

-I don’t care, you are too young for this shit.

-Dean! You were thirteen the first time you hooked up with someone! And if I remember correctly, she was way older than you.

-That’s… different.

-Why? Because he’s a guy?

-No, Sam, because you are too innocent, and besides, you have me to take care of you. I didn’t know better.

-It’s not like you didn’t enjoy that.

-I didn’t say that! It’s just that it’s better to wait a bit more until… you know.

-Dean, it’s not like I’m just gonna fuck the guy tomorrow, we didn’g even have our first date yet.

-Sam! I said you won’t have no dates, and that’s final!

-I’m not gonna listen to you anyway…

It was the first time that Sam had used that bitchy attitude that he usually reserved for his father. Dean was so pissed that he didn’t even register what he was doing until he had Sam lying on his lap, across his knees, with his pants just under his asscheeks, and the first slap resonated around the empty room. 

Sam shut up abruptly, a sharp intake of breath preventing any words from falling from his lips. And he shivered. Or was it Dean the one that had started shaking? The silence was heavy in the living room, and it seemed like time had stopped. Dean let go of his hand and it smacked again against Sam’s pale cheek, coloring it in a lovely pink that he suddenly felt the need to lick and taste. He slapped Sam ten times, and by the end of it, they were both panting and hard inside their jeans. Dean was so shocked that he pushed Sam away and scrambled up and to the bathroom, where he started the shower without even getting rid of his clothes. The water was fucking freezing.

He didn’t notice the change at first, because after that first time, he had been so preoccupied with not thinking about Sam, that he had started avoiding the kid with all his might. Which, of course, had pissed Sam off to the point that made him, for the first time in his life, behave badly. Well, that’s putting it mildly. One month after Dean had started his I wanna fuck my little brother until next week freak out, Sam was done with his bullshit and decided that getting wasted and high as an skyscraper, was a fantastic idea. Dean was absolutely furious when he got a call from his father telling him that Sam had been brought home by a frigging hockey player (and how did this father even know that??), and that to move his ass and come back home to take care of him, because he was leaving. He had been ten seconds short of putting his dick inside Martha, or Monica, or whatever, and as soon as he apologized about having to leave, he was slapped across the face. Sam was so fucking dead, the little shit.

So the second time that he spanked Sam, it was actually totally deserved. But he still got hard while doing it and he was sure that he had heard Sam say “fucking finally” in the middle of the whole thing. Smirking. Now why would he do that? He had no clue. But he was sure that whatever this was, it was dangerous. And he didn’t care because he was addicted and there was no changing that. Sam’s ass, cherry pink and with his handprints as a shameful reminder of misbehaving. He jerked off that time, instead of trying to kill his erection with a cold shower. He had been interrupted, after all. 

When he came out of the bathroom, Sam was sleeping peacefully in the bed, on top of the covers, exactly in the same position that Dean had left him in. Something stirred inside Dean, something dark, and uncomfortable, but at the sight of that little secret smile on his brother’s lips was enough to shut up his brain.

They started a sort of routine after that. Sam would build up his anger at being ignored until he exploded and did something bad, and Dean would spank him when that happened. Dean wasn’t an idiot, and after the third time he was sure that Sam was doing shit on purpose so he would be punished. And who was him to judge? He was trying to make Sam feel impatient and pissy exactly for the same reason. They didn’t talk about it. They acted like normal the rest of the time. It was just that, from time to time, they needed to unwind, and that was the way they had chosen to do so. Nothing weird about that, right?

The first time that Sam was allowed to hunt something by himself (his father had actually thought that the hunt was a miss, and just wanted to get rid of Sam for a few days), it ended up being a werewolf. When Dean finally found Sam, after receiving the call, his brother’s voice desperate and wobbly, like he was crying, scared, and why was Sam alone, he should always be by my side, where I can see him, where I can protect him, he didn’t realize he was screaming until Bobby, John’s friend and the hunter that had recommended the case, told him to shut up already. His baby brother was covered in blood. There was a huge gash at his side, so deep that he was sure that he was actually seeing one of his ribs. And there were also guts everywhere (thank god those didn’t come from Sam, oh Sammy, please wake up ).

Dean was running so high on adrenaline that he made it back to the motel in less than half an hour, then proceeded to chew his father off for being so stupid and not bothering to check the hunt before sending off Sammy. He could have died!

-Dee…

Sammy always used that nickname with him when he was upset, or scared, or hurt, and at that moment, he was probably feeling all of them. Dean lied in bed next to Sam for the next few days, after he was patched up. He needed to hear his brother breathing, or he couldn’t fall asleep. 

~~~~

-Dean, I’m FINE already, let me get up from this bed. I’m bored!

-No can do, Sammy. You’re on bed rest.

-Until when?

-Until I say so~

-I’m done. I’m not going to listen to your bullshit. I need to move around, man, or I’m gonna go crazy…

-Sam go back to that bed or I swear to god that I…

-That you, what?

-...Nothing.

-Dean…

-I said it’s nothing, Sam.

-Dean, look at me. Or what?

Dean turned around to look at Sam, who had his gaze fixed on him, a blush creeping up his cheeks. And Dean gulped, because he understood. He understood that gaze, and what it meant, and he couldn't believe that Sammy would look at him like that. 

-You’re a fucking tease, you know that, huh, Sammy?

-I’m kinda surprised it took you so long to notice. I never took you for a fool.

-Oooh? I’m no fool, just surprised that someone as uptight as little Sammy could be so… perverted.

-Look at who’s talking, the one who gets hard when spanking his little brother. 

-Like you’re much better. You get off on the thought of your big brother making you squirm on his lap, slapping you nonstop, until your little ass is so sore that you have trouble sitting down?

-Ah, fuck, yes, Dean, you have no idea.

-I think I do…

Sam didn’t waste any time, and got naked without even waiting for Dean to reach the bed. Then, he got down on his knees and backed his upper body against the bed, presenting his ass, so pale, so tempting, and all for Dean to use and abuse as much as he wanted. And that’s what he did. His little brother was so responsive, so alive. So fucking pretty in pink.

The first time his cock breached that same ass that he had been worshipping and dreaming about for months, it felt like a revelation. Sam was finally complete, Dean was completing him, because they were both one and the same. Same blood, same flesh, same soul. Forever.

Sam was sixteen and he got strange looks when he told people that his big brother usually punished him with a good ass spanking. They thought that that kind of thing was only suitable for little kids, the morons. Sam obviously didn’t elaborate in which other ways Dean took care of him after beating his ass cherry red.
