Notes
     Prompt: I would like to request weecest (bottom!sam) + praise!- and/
     or daddy!kink? maybe with some angst because dean wants sam a lot and
     he knows it's wrong but he just can't stop?
     I still suck at summaries and titles, no one was surprised. Unedited
     because I am sleepy. This is also my first time trying a hand a
     daddy!kink, so don't judge too harshly there, ok? <3

Dean knew full well that the way he was staring at his little brother wasn’t
right, but he couldn’t break away. It was like looking at a fatal car
crash—made your heart race, your skin crawl, and kept your eyes glued. He
wanted to back out of the room, forget what he saw, but there was no way he was
going to be able to retreat. Not now.
He was rooted to the spot as he watched his baby brother’s cock thrusting up
through his fist as he massaged his balls with the other. Sam’s head was tossed
back against the pillows and he groaned out Dean’s name. His eyes were closed,
but it was obvious that Sam knew he was watching. This was intentional.
“Sammy,” Dean choked out the words as best he could, but they were tight and
and made his chest ache. “What are you doing?”
“Dean, nnngh, help?” Skin pinked with a deep flush, his breathing was coming
heavy and fast. There were two splotches of dark red, one on either edge of his
bottom lip, where he had chewed them open trying to keep quiet. Dean wanted to
know what it tasted like and that guilt instantly settled in his gut. He tried
again to look away and, once again, failed.
His voice was shaky. “H-help?” Was his baby brother asking to him to help him
get off? He seemed to have a solid handle on that without Dean. He couldn’t
touch him, not like that. For one, the kid was young, and it was his brother.
Nonetheless, his hands were itching to feel that skin he knew had to be petal
soft. “You don’t need… I can’t.”
“Please? Dean, I need you to fuck me.” Fingers teased over his hole and the
sound that came from Sam’s mouth was debauched and needing. He could see the
pink of his tongue, slick with spit. What would the inside of Sam’s mouth taste
like as he licked inside of it? Would Sam let him take what he wanted or would
he give back as good as he got? The boy moaned, drawing Dean’s attention back
as the tip of one finger slid inside that tight muscle.
Shit, this was going to ruin him.
Dean wanted to touch, wanted to take the boy and show him what actual pleasure
was, but the thought made his heart flip. To do that was immoral and illegal,
and he couldn’t. This was his little brother. He was supposed to protect him,
not corrupt him. But he could see Sam start to wince as he slipped that finger
further into his dry hole. It couldn’t be comfortable. If Dean helped him,
maybe he was just showing the kid the ropes? That’s what brothers did.
“Please?” The words came out a whisper and a whine combined, and Dean crumbled.
It was fortunate that he had been in a rush to clean up from this morning and
had just shoved the small bottle of lube into his back pocket. If he had to
leave and fetch it from his room, he would have convinced himself that there
was a good reason not to do this. But with it now in his hands, he was struck
with the thought that he was about to have his fingers inside his little
brother. Dean’s cock jerked in his jeans, drawing attention to how painfully
hard he was.
“I’ll take care of you, buddy. It’s ok.” He murmured softly as he removed Sam’s
fingers, allowing him room to tease one of his slicked fingers around his pink,
hairless rim. He hadn’t paid attention until now, but there was none of that
growing fuzz on his balls or the base of his shaft either. The kid was old
enough to have hair wasn’t he? Fuck, had he shaved because of Dean? Because he
wanted this?
Dean’s left hand squeezed roughly through his jeans, trying to relieve some of
the pressure as the fingers of his right kept petting his baby brother’s hole.
It wasn’t teasing—he couldn’t fucking stop—more like stroking—couldn’t believe
how soft the boy was.
“De, please?” Teeth were back in the holes of those bloodied lips and Dean
couldn’t take his eyes off that mouth as he sunk his middle finger all the way
into his brother. “Nnng, fuck! Another, need it now.”
God, that whining lilt to Sam’s voice shouldn’t have revved him up even more.
Just as he was asked, Dean began inching another into the boy beside the first.
If Dean hadn’t gotten off this morning, Sam’s face would have made him cream
his jeans. Closed eyes, a solid blush, and just the hint of that spit-soaked
tongue nudging against the edge of his bottom lip as he panted. He wanted so
badly to know how that mouth would feel wrapped around his cock, but that was
too far over the line. This was helping, that was taking advantage, and he
wasn’t going to do that to the kid.
He twisted the digits slowly, crossing and uncrossing, stretching him out for a
third finger. With the way Sam thrust down on every movement, he wasn’t sure it
would be necessary—wasn’t sure they’d make it that far.
“Fuck me, Dean.”
He shook his head. “You aren’t stretched enough yet.”
“I can take it.”
“Sam, it’s gonna hurt.”
“Won’t, promise. Just use a lot of lube. Need you, now, please!” He could see
tears prickling at the corners of the kid’s eyes, threatening to
spill—threatening to make Dean regret this in the first place.
“Ok, it’s ok.” It took him a try or two before he got the zipper of his jeans
all the way down with lube-slicked fingers. He focused on his own clothes as he
removed them, careful not to brush the fabric against his throbbing cock. Shit,
how had he gotten so hard and not noticed? “I’m gonna take care of you.”
When he looked up to find Sam on his elbows and knees, with his ass in the air,
Dean had to grab the base of his dick or he was going to come all over the back
of his brother’s thighs. The little brat had to go and wag his hips, too,
taunting him.
He got on the bed behind Sam, sliding them both to the center, allowing more
stability as Dean pushed just the head inside. Even with that, the boy’s rim
was stretching wide. It had to have hurt, but the way that Sam thrust his
entire weight back, plunging Dean all the way inside, said it didn’t.
“Sam, Sammy, shit, be careful.” The words were bit out around a moan that he
was keeping in. He was helping his brother, he wasn’t supposed to be enjoying
it.
“You won’t hurt me, not really.” He rolled his hips, causing Dean to slide out
before thrusting back again. The moan came out that time as his abdominals
crunched forward, pressing as deep into Sam as he could. “Like it when it hurts
a little.”
“God, ohhh.” His hands were gripped tight around bony hips and, hell, if it
didn’t look like it could have been a girl’s figure.
“Please, fuck me, Daddy.” Innocence washed his words clean and Dean sat
shocked, dick still sheathed in slick heat. It twitched inside of Sam, they
both felt it, but he couldn’t believe that what he just heard was right.
He shook his head to clear ears that were surely clogged. “Did… did you…”
The boy’s voice was much clearer this time, but still with that childish tone.
“Daddy, I need you. My tummy feels weird.” He whimpered as he slowly pulled off
and sank down on Dean’s cock again. “Make me feel better, please?”
Dean knew then that he was going to hell, but he couldn’t give a damn. This
wasn’t about helping anymore. He needed this—wanted this—as much as Sam did. He
wanted to ruin the boy for anyone else. His thrusts weren’t so much that, as it
was dragging Sam back onto his cock repeatedly. It didn’t matter what the
motion was, as long as he was buried to the hilt every time.
“Do you like fucking me?”
“Yes, oh god. You feel so good. Sam, I… shit, I didn't know you'd be this
tight,” he said through gritted teeth. He was already on edge, but he needed to
hold on for just a little longer. It felt incredible and he didn’t want to give
it up because he needed to come.
The boy was looking over his shoulder at his older brother, mouth hanging open
as he unabashedly moaned and arched his back. Dean thrust harder, pounding into
him, their skin smacking loudly as Sam’s ass was pulled repeatedly into the
cradle of his hips. It was fucking sinful. He never wanted to stop.
“Am I a good boy for you, Daddy?”
That voice—those words—Dean was undone. “You’re such a good boy. So tight, so
willing, so beautiful. S-shit, Sam. You’re fucking perfect.” Nothing was
keeping the words in anymore and he didn’t care. Let Sam know how he felt. How
he must have always felt. “God, I love you so fucking much. Fuck!”
He meant to pull out, but he didn’t have a chance before he was spilling inside
of his little brother. Dean couldn’t believe that of the two of them, he was
the one who came first, and the one who was whimpering his way through an
orgasm. At least he had the presence of mind to get a hand on Sam’s cock and
jerk him until he was spilling over his hand. It was on the tail end of Dean’s
orgasm—that fluttering muscle pulling one more pulse of come from his dick.
They were breathing hard, but neither had any desire to separate, to lay down.
They felt good melded together like this. Maybe they should stay this way.
“Love you, too, Dean.”
