Cas knows that something is up when his father enters the room, his steps are
too heavy, and when the boy looks up his father’s face is angry.

“Cas,” He says. “Is there anything you want to tell me?”

Cas furrows his brow, trying to think if he’s done anything bad lately. “N-no?”
He says after a moment of contemplation. 

His father’s frown deepens. “Really?” He asks. “You don’t know anything about
this?” From behind his back he brings out a toy. A big, flesh-colored one that
looks like a thingie. Cas immediately recognizes it as his father’s, although
he secretly plays with it sometimes, putting it inside his hole. But Cas’ daddy
doesn’t know about that. Or at least, he didn’t before. Cas swallows nervously
when he sees that the toy is still slick with lube from the last time he used
it, and he realizes that he forgot to clean it. He feels his face flush red and
he knows there’s no hiding it.

“I- I’m sorry, Daddy!” He cries, tears welling up, threatening to spill. 

“Did you use this?” The man asks incredulously.

Cas ducks his head and nods, tears spilling down his cheeks.

“Cas, these are not your toys, you have your own toy.” Cas’ daddy reminds him.
Cas just puts his face in his hands and cries harder, he only has one toy, and
it’s not near as big as Daddy’s! It’s just a little one. 
But then Cas’ daddy is there, kneeling in front of him and pulling his hands
firmly away from his face.

“Cas.” The man says sternly. “I told you not to play with my toys, you remember
that, don’t you?”

Cas closes his eyes tight and nods, he does remember.

“And do you know why I told you not to play with them?”

Cas shakes his head.

Cas hears his daddy sigh.

“Cas, open your eyes.” He says. Cas does, and his daddy is still frowning down
at him, which he doesn’t like. “I told you not to play with my toys because
they’re too big for you, and I didn’t want them to hurt your little hole. Do
you understand?”

“Y-yes, Daddy.” Cas mutters.

“Okay. Now, I’m sorry baby, but you’re going to have to be punished.” 

Cas can’t stop the little sob that forces its way past his lips. He doesn’t
want punishment! He looks sadly up at his father. “Do you have to?” He asks.

“Yes, I do.” His daddy says, sighing. “I want you to understand that when I
tell you not to do something, you don’t do it.” He stands and goes to sit on
the couch. “Now come here.” He demands.

Cas walks over slowly, heavy with dread.
 
-o-
 
Dean hates to have to punish Cas, it breaks his heart to have to hurt him even
a little. That said, it’s possible he enjoys spanking the boy, just a tad. Cas
comes over, still crying quietly, to crawl onto the couch and over his father’s
lap, until his little butt is raised up, presented, over Dean’s legs. He pulls
the boy’s Tweety Bird pajama pants down just past his little ass, noting the
lack of any underwear. 

He makes sure the boy is settled before giving his sweet bottom a slap on one
cheek. It jiggles temptingly, quickly turning red. Dean gives the other cheek a
spank, and then the other,  and he continues to do this until Cas’ whole ass is
cherry red, and Dean’s cock is rock hard beneath him. He’s not really sure what
it is about spanking his small son’s ass that gets him off, but he’s sure he
should feel worse for it. He’s so entranced by the bright color that he almost
doesn’t notice that his son is sobbing now, hands curled into tiny fists in the
couch, snot and tears running down his face. 

“That’s okay, baby.” Dean says, rubbing his hand soothingly over the tender
flesh. “That’s all the punishment you get. You’ll be okay.”

Cas sits up, not bothering to pull up his pants, and launches himself at his
father. Dean catches him handily, wrapping his arms around the boy and pulling
him close. 

“Shh, shh.” Dean soothes. “Daddy has you.” He rubs circles on the boy’s back
until Cas’ sobs begin to taper off. After a while, Cas pulls back, rubbing
under his eyes with small fists. 

“Sorry, Daddy.” He whimpers. 

“That’s alright, bud.” Dean tells him, “But you understand why I had to punish
you?”

Cas nods. “Y-you said not to play with your toys a- and I did anyway.”

“That’s right.” Dean gives the boy a gentle peck on the lips. “You’re not big
enough for daddy’s toys yet.”

Cas huffs, looking up at his father through red-rimmed eyes. “But I am  big
boy!” He protests. “I can tie my shoes an’ everything!” 

Dean suppresses the urge to laugh, pressing his lips together. “Now, baby.” He
says, bouncing the boy on his knee. “You sure are growing up, but you’re not
big enough for daddy’s toys or daddy’s cock.Iwill tell you when you’re big
enough, understand?”

Cas pouts, bottom lip sticking out cutely, but he nods. 

Dean smiles at him. “That’s a good boy.” 

Cas whines and presses his face into his father’s neck, wiggling and pressing
his little bottom into his father’s lap. 

“Daddy!” He squeaks. “Your thingie is excited!” 

“Hmm, you always make daddy’s cock excited.” Dean tells him, kissing him again.
This time he slips his tongue in and Cas opens his mouth eagerly. He kisses his
son slowly, pushing his tongue in and out of the boy’s small mouth. He lets his
hands drift town Cas’ back and he cups his little butt tenderly. 

“How’s it feeling?” He asks.

“Hurts.” Cas whines. 

“How ‘bout I give you special kisses on it?”

Cas looks up and nods excitedly. “Yes, please!” 

Dean helps his son step out of his pants and then lays him out on the couch, on
his stomach, bottom in the air. Then he leans down to place gentle kisses up
his boy’s thighs. Cas coos and wiggle his little butt as Dean goes up higher,
peppering his rosy buns with wet smooches. 

Cas just hums happily, resting his head on his folded arms and letting his eyes
slip closed. Dean keeps kissing until Cas is loose and pliant, yawning
sleepily.
 
 
After dinner, Cas and Dean take a bath together, and Dean cleans his boy
thoroughly. Very thoroughly. 

Cas is on his hands and knees in the tub, little ass presented to his father.
The water sloshes around his elbows. 

Dean is behind him, pushing his cock up into his boy’s crack. He’s careful not
to accidentally push into the boy’s hole, he just presses Cas’ cheeks together
to make a soft place to fuck into. When he gets close he stops and has Cas turn
around. 

“Here, baby.” He says, taking hold of his cock and pressing it to his son’s
lips. “Open up for daddy.”

Cas parts his lips, and Dean slowly pushes in. He closes his eyes and bites his
lip, because his boy has the sweetest little mouth he’s ever had the pleasure
of being inside, it’s perfect. Cas can only get a little of his father’s length
into his mouth, but he hums around it happily, gazing up through wet
eyelashes. 

Dean rocks into the sweet heat, and Cas gags a little but he doesn’t pull away.
He’s gotten pretty good at sucking cock, and Dean caresses the side of his face
and tells him so.

“I’m so proud of you, babydoll.” He murmurs. “You’re such a good boy, sucking
daddy’s cock so good.” He rakes his fingers through Cas’ wet hair, gripping it
tightly and pulling his son further down onto his length. “Fuck, yes.” He
hisses. 

When he comes, he holds Cas’ head still on his cock, and the boy tries to choke
down his come. He fails miserably. It squirts out the corners of his mouth,
running down his cheeks to drip off of his chin and into the water. When Dean
lets go of his head, Cas pulls back, gasping for breath. He coughs for a
minute, but then he’s smiling up at Dean and licking his come-covered lips. 

Dean uses his come to slick the way when he stuffs three fingers into his boy’s
tight little ass, pounding roughly away until Cas comes with a wail. He’s such
a good boy, even coming just from prostate stimulation now. Such a sweet little
thing. 

Lying in bed that night, with his son tucked up against him, Dean wonders if
Cas isn’t closer to being ready for his cock that he originally thought.
