Summary
     Principal Castiel had to admit, he's a little obsessed with one of
     his students, the deliciously small Dean
Notes
     Warning: This fic involves castration as a kink. Explanation of how
     the heck this is even a kink and how it works here.
     This is an Alpha/omega kink prompt fill. Expect more porn than plot,
     and lots of power imbalance between Cas and Dean. Mind the warnings
     and kinks in the tags.
     Anonymous asked:
     13 year old Dean castrated as soon as he presented as an omega, 4
     years later and he still looks relatively 13 years old even when in
     his junior year of high school. 34 year old Castiel is the school's
     principal and has been observing the beautiful omega for 3 years. One
     day he sees Dean cornered by 3 alphas, something in him screams at
     him to protect his bitch. (Small, submissive, shy, blushy Dean/firm
     yet kind, strong, possessive Cas)
     Filled on Tumblr, September 2014

Castiel stood in the office doorway, watching the hoard of teenagers make their
way through the high school hallways. The overwhelming scent of raging teenage
hormones would be too much for most alphas, but Castiel had years of practice,
and the scent would clear once everyone got to class.
A familiar, soft voice piped up from the crowd. “Hey, Mr. Novak.”
Castiel’s eyes tracked until he found Dean Winchester. The boy was just as
small and skinny as he had been the year before, face just as soft with not a
whisker in sight. It was hard to believe the boy was 17, he looked like he was
barely a day over 13. 
Which was of course because his family had elected to castrate him the day he’d
presented as an omega. It wasn’t a terribly common procedure, although it was
far more common for the most beautiful omegas, as it made them highly sought-
after. 
Recently Dean had taken to wearing skin tight jeans, which showed off his
barely there bulge. Castiel couldn’t help but wonder about what Dean looked
like under those jeans, he’d never had the chance to knot a castrated omega,
but he’d heard plenty of rumors.
“Hello, Dean,” Cas said, smiling down at the boy. 
The boy smiled at him, then blushed and ducked his head, continuing on his way
to class. 
Castiel watched him go, unable to stop his eyes from tracing the boy’s slight
frame. 
===============================================================================
Later that day, Castiel found himself wandering the halls in the middle of
third period. He had felt restless, and decided a hallway check was a good
excuse for a walk.
He couldn’t stop thinking about that boy. Curiosity and desire were muddling
his brain. 
As Castiel approached a corner, he heard the low voices of what sounded like
alpha teenagers. 
“Hey, little boy, you wanna show us that cute little dick of yours?”
“Yeah, I’ve heard your cock shriveled up after you had your balls taken, is
that true?”
Castiel growled softly, knowing exactly whom he would find when he turned the
corner.
Sure enough, a small group of alpha boys had Dean Winchester pinned against a
wall. He looked even smaller with the way he was cowering in fear.
Castiel’s instincts were kicking into full gear. Protect your bitch!He growled
and hollered at the boys, “My office, now!”
The young alphas scattered, leaving Dean shaking against the wall. The moment
Castiel reached for him the boy threw himself into his arms, pressing his face
to Castiel’s chest.
“Thank you, Mr. Novak!” he managed to gasp out, still breathing heavily.
“Hey, it’s okay Dean, you’re safe now,” Castiel said, running a hand up and
down Dean’s back in a soothing gesture. “I’ve got you.”
They stood there for a moment, Dean clinging to him tightly. Castiel waited
until the scent of fear faded, and he was about to let go of the boy when he
smelled something else.
Slick.
Castiel cleared his throat and tried to pull away, but Dean only held tighter.
“Please, Mr. Novak…”
Taking a deep breath, Castiel pushed Dean out of his arms and held him at arms
length. Dean blushed and dropped his head in submission.
“You’re too young, Dean,” Cas said.
“I’m 17!” Dean snapped, then flushed and bit his lip. “Sorry…”
Castiel frowned. “No, you’re right. You’re older than you look, it’s easy to
forget sometimes.”
Dean glanced up at the older Alpha. “I see the way you look at me,” he said
softly. “You want to know. You want to see.” Dean ran a hand down the front of
his jeans. “Let me show you, Alpha?”
Castiel gaped at him for a moment, tried to tell himself no, and then promptly
caved. He grabbed the boy and dragged him into a nearby empty classroom,
quickly locking the door and pulling the blinds. 
Castiel turned back to Dean to find all the bravado of the previous moment
gone. The boy stood timidly in the middle of the room, watching Castiel.
Too far gone to turn back, Castiel slowly stalked towards the boy. “Show me
your pretty little dick, Dean.”
Dean visibly relaxed at the direct order, and he started to unbutton his jeans.
He slowly pushed them off his hips, and Castiel groaned when he realized the
boy wasn’t wearing underwear. 
Castiel stared hungrily as Dean revealed his small, soft cock. It was only an
inch or two long at the most, and where the boy’s balls would have been was
just soft, hairless skin. 
“Did it shrink after you were castrated?” Castiel asked, unable to help
himself. He stepped closer to Dean, but didn’t touch him.
Dean blushed and nodded. “Yeah. It used to be bigger.”
Giving in, Castiel reached forward and stroked a thumb up and down the short
length of the little cock, grinning when it twitched under his touch. 
Dean whimpered, leaning into Cas. 
“Does that feel good?” Castiel asked. 
Dean nodded quickly, clutching to Castiel’s shirt. His hips jerked a bit and he
moaned.
Castiel then dropped to his knees and pulled the boys dick into his mouth,
sucking on it. It was so small he could easily hold the whole length in his
mouth, even as it started to grow hard it wasn’t even two inches long. 
“I- I can’t,” Dean managed between moans. “I can’t come that way.”
Castiel stopped sucking and stood up, taking Dean’s hard little cock in his
hand, stroking it. “You need a cock in your ass to come, don’t you?”
Dean flushed, nodding.
Castiel grinned. He’d heard that was the best part of castrated omegas: they
were sometimes fully dependent on penetration for release. Done waiting,
Castiel pulled Dean over to the desk and bent him over it, yanking his pants
down and exposing his ass. Slick readily leaked from the boy’s eager hole. 
Castiel quickly pulled out his own, much larger cock and thrust inside the
boy’s ass with one hard push. He reached around and clamped a hand over the
boy’s mouth just in time to smother his loud moan. Too tightly strung for
patience, he immediately set a fast pace. He would take it slow the second time
around.
“I’ve always wanted to knot a castrated omega,” he said, groaning as he felt
his balls slap against the smooth skin where Dean’s own balls should have been.
“You’re so small and delicate, the perfect bitch.” 
Dean moaned into Castiel’s hand as the other one reached down to tease his cock
with his fingertips, running down the length and over the smooth skin at the
base, then back up again. 
“God, I love your little cock.” Castiel groaned. “It’s so fucking pretty.”
Dean whimpered and moaned as Castiel’s knot started to grow, filling and
stretching the boy. Castiel grunted as his knot snapped into place, tying him
to the boy, and he let out a long groan as he came, come starting to fill the
omega’s ass.
At almost the same moment, Dean came with a long, whining moan. Castiel pulled
his hand back from the boy’s cock and was fascinated to realize it had been a
dry orgasm.
After a moment, Castiel easily lifted the boy and moved them both to the chair,
mindful of the knot tying them together. He sat down, bringing Dean down onto
his lap.
The boy settled into his chest, glancing up at him shyly. “Did you really mean
all that?”
Castiel raised his eyebrows in surprise. “About how much I like your pretty
little cock and your perfect body?” 
Dean blushed and nodded, reaching down to cover his quickly shrinking dick with
his hands.
“Of course I did,” Cas said, pulling Dean’s hands away so he could admire him
some more. “You’re perfect, Dean.”
Dean blushed, but when he looked up again he was grinning.
