Summary
     When the demons attack an angel sanctuary, the demon brothers Dean
     and Sam discover a terrified angel youth named Castiel and convince
     him that if they 'mark' him he will be safe.
Notes
     So I marked this underage even though Castiel doesn't really have a
     age. In my mind he's the equivalent of 16-17ish but also angels as a
     species are smaller then demons. So yeah.
 
Castiel was going to die.
All for a few dusty books, all because he figured he had enough time; that he
could slip passed demons easily. The angel’s wings quivered furiously and he
focused only on making them stop, on being silent. Perfectly still and not a
single sound, that was what he needed right now.
The librarian was dead.
From under the long wood table, hidden behind the heavy white tablecloth,
Castiel could see her empty eyes looking blankly at him. When she had found him
in the library gathering books the older angel had rushed him under the table,
telling him not to make a sound. Seconds later the doors slammed open and
Castiel watched them kill her, a singe swipe of their blade to her neck, they
didn’t even look at her. The demons raiding the sanctuary were going through
the rooms, walking down the isles of books and looking for any angels hiding.
They were killing them all.
There was a great winter storm outside, the power of the winds prevented angels
from taking to the air and if they rushed away from the sanctuary the freezing
cold would kill them slowly; there was no escape from the slaughter.
Tucked under the table Castiel focused only on being a stone, still and
unmoving, not a single sound. The demons were talking, walking all around him
but he remained calm, he went within like in meditation. Paying attention only
on the stillness, if he listened to them his wings would surely shake loudly
and tears would fall, he’d be caught. Curled up in a tight ball, he waited
until the library was still, until there was no sound and he tentatively let
himself listen. There was silence in the room; there were the distance sounds
of battle and the howl of the storm from the windows but the room itself was
still. Castiel very slowly opened his eyes and did not look to where the
librarian’s dead eyes would pierce him. Very, very gently he moved, took each
inch agonizingly slow in case they were still there, waiting for him to think
it safe and come out. But he moved and no one jumped out, no hand grabbed him
from under the table. Castiel very solely crawled down the length of the table,
all the way down to the end where he could see the heavy doors to the
consecrated part of the library, where the most prized books were kept. It was
blessed and sealed to keep demons out; it would be the safest place for him to
hide until the demons left.
Logically Castiel knew he should look around, logically he knew he needed to
check but as he stared at the ornamental door he couldn’t look away. His wings
quivered but Castiel made himself move, once he was out from under the table he
should have stood, should have run the rest of the way but he couldn’t. Fear
wouldn’t let him so he just kept crawling, inching to the door until he could
reach out and touch it. Once his fingers brushed the ancient wood he ducked his
head and nearly vomited. Terrified, he struggled not to and pushed the door
open only enough for him to get through. There was a table, much smaller in
this room and Castiel crawled under it, hid behind the heavy cloth and curled
up against the wall, his wings trembling as he tried to be still, tired to find
the quiet place again.       
 
It could have been minutes or hours but a loud thump and muffled voices in the
library made him jerk. In his mind he chanted a prayer, a plea to the father
but it went unheard because the door to the consecrated room banged open.
“This it?”
“Yeah, give me a second to undo the seals and we can go poke around.”
“I dunno, Sammy, looks like a bunch of old ass books to me, not much else,
nothing shiny at all.”
“The books of angels are worth far more then any of their gold or jewels Dean.”
“Yeah, yeah, make with the seal breaking already.”
Castiel listened as one of them chanted, spoke his own language and he coiled
tighter under the table as the spells lifted and let the demons into the room. 
They couldn’t do that.
Demon’s couldn’t use angelic tongue, they couldn’t use angel spells, it was a
fact and Castiel tried not to cry with the knowledge that this one just had.
The chair across Castiel jerked, pulled out and he felt terror consume him as
two legs came under the table, inches from where the angel was hiding. The long
spindly tail of the demon wagged along the floor, slithering like a snake.  
“You gonna take long? I wanted to see if there was anything worth looting,” the
demon sitting spoke and the other moved around the room, Castiel could hear him
pulling books off the shelf.
“There won’t be anything of worth here, it’s a sanctuary not an armory,” the
one looking at the books replied. It was a correct assumption; the sanctuary
didn’t have any wealth, their greatest possession were the very books these two
had come looking for.
“I’d rather go looking for treasure I won’t find rather then watching you snoop
through books,” the ones sitting groused but didn’t move to leave. Rather he
stretched his legs out and his boot collided with Castiel’s arm. With his free
hand he covered his mouth to muffle any sound, his wings quivered and he
couldn’t stop them anymore. Tears dripped and horror filled his very being, he
was going to be discovered, he was going to die.
“...you smell that?” The sitting one asked, shifting in the chair, sitting up
and pulling his boot from Castiel.  
“What?” The other asked and Castiel watched as the demon sitting draw a blade
from his boot, long and wicked, the instrument of Castiel’s death.
“Salt…I smell salt,” he announced and the angel realized it was his tears
seconds too late as the table clothe was ripped back and he was revealed to the
two murderous demons.
“Whoa, that’s a tiny angel,” the one with the blade said and Castiel hid,
ducked his head and clenched his eyes tightly, not wanting to see death coming.
“A juvenile, I’ve never seen one this young before, they usually have all their
fledglings in the sealed rooms. He’s got to be under a hundred years old,” the
voice sounded interested, curious as Castiel stayed curled up and trembled.
“Why isn’t he in the sealed room?” The gruffer voice asked and Castiel knew it
was because he was an idiot, a stupid, stupid idiot. The demons didn’t break
into the sealed room. All that was ever kept in there were the young, from eggs
all the way to the juveniles like Castiel. The demons never got into the room,
but then they weren’t supposed to be able to undo any seals and one of them
already had.   
“Looks like he’s going to piss himself.”
He might yet.
“There, now you have something to entertain you while I look through their
books,” one said with a huff and Castiel whimpered when boots approached him.
He screamed out when he was grabbed, dragged out from under the table howling.
“Jeez, shut the hell up you dummy, you’re gonna lure others and then you’ll be
sorry,” the demon grumbled and Castiel’s fell silent, his voice frozen at the
idea of more demons. After the battle was done he’d heard that the demons would
get bored, they would torture angels, rip their wings off.
“Better,” the demon said and he sat Castiel on the edge of the table, peeling
his wings back because Castiel was curled up in them. Rough hands yanked his
own arms from his face and hand in his hair hurt until he was forced to look
up.
When he saw the demon finally he cried again, his vision blurred as the
terrible monster peered at him. He was huge and had all sorts of weapons on
him, his eyes where a demonic yellow, he was everything Castiel had ever heard
about demons, down to the curled horns sprouting from his hair.
“He’s kinda pretty,” the demon inspecting him muttered, his clawed fingers
digging into Castiel’s chin and lifting his head to get a better look at him. 
“Definitely pretty.”
“Typical Dean,” the other demon, even bigger then the one holding Castiel, said
with a roll of his eyes.
“Why you crying baby boy?” The demon holding him asked, his voice going soft
and his hands not holding Castiel painfully tight anymore.
“Hmm, come on, be a good little angel and tell me whats got you crying so
hard,” he pressed, cooing like a concerned angel parent would.
“…c-cause…you’re gonna rip my wings off and eat me.” Castiel managed to get
out, not wanting to answer but after everything, he desperately wanted comfort,
any comfort, from anyone. His answer made the demon snort and chuckle.
“I dunno, you look a little stingy to make a good meal, ever eat an angel
Sammy?” The demon questioned the other with a laugh and the one looking at the
books snorted.
“Not many demons do that anymore, not when there are way better meals around.”
“True, I’m partial to rabbit myself do you like rabbits sweetheart?” The demon
watching him asked Castiel with an easy smile, the kindness confusing Castiel
as he got his tears under control. He gave a little nod and the demon smiled
wider, he used the tablecloth on the floor to wipe Castiel’s face, his tears
and snot cleaned up.
“That’s better, much nicer when you’re not so terrified,” he told the angel and
the boy watched him, not knowing what to think faced with this.
“Demons are bad, they hurt angels, tear off their wings,” he whispered and the
demon watching him nodded solemnly.
“Some demons are real bastards, but me and Sammy we’re nice demons, were not
looking to hurt you baby. Right Sammy?”
“Nope,” the other demon said with out looking up from his book, uninterested in
them and Castiel could understand, he often was scolded for reading too much.
“So that’s Sammy, my baby brother,”
“It’s Sam,” the bigger demon corrected.  
“Yeah, yeah, and I’m Dean. What’s your name little angel?”
“…Castiel,” he finally said, voice soft and shy as the demon gave him another
warm smile and lifted him up. Before Castiel could panic Dean put him on his
lap, sat Castiel on his knee just like a fledgling. The demon was so big that
it made Castiel feel like a fledgling. Angels were small, they rarely grew
beyond five lengths and were slender and light, meant for flight. Demons were
much bigger, they were always eight or nine lengths, broad and bulky, meant for
war. The demon Dean put his hand on Castiel’s knee, he could almost close his
hand around it completely and Castiel was nearly full-grown.      
“Castiel, that’s a pretty name, tell me sweet heart why aren’t you in the
sealed rooms with the other little ones?”
“I came…I came to get books, to keep them safe,” he admitted with a red face,
shamed by his greed and love of possessions.
“Sounds like Sammy!” Dean laughed, looking back to demon going through books.
“He’s always been like that, wanting to read the books and take all of them
with him, means he’s smart though, so you must be too.”
Castiel couldn’t help but flush under the praise, most angels thought he read
too much, that he needed to spend more time doing other things.
“You’re a sweet little boy Cas, do you know much about demons baby?”
“N-not really I guess,” he admitted, beyond the fact they were monsters and
would kill him horridly given the chance he knew virtually nothing.
“Demons can be pretty mean, especially with such a sweet angel like you, you
have to be careful you know?” Dean slid Castiel higher on his leg, Castiel’s
shoulder bumped the demon’s chest and Dean pulled Castiel in close to him, the
warmth of another living thing couldn’t be denied and the angel curled up to
him, needing comfort desperately.
“The others will wanna hurt you, make you cry something awful,” he explained
and tears pooled in Castiel’s gaze and he felt his wings start to quiver in
fear. Dean was a demon and Castiel should know better but he was scared, so
scared and he wanted to be safe, he needed to feel it. Crumpling he pressed to
the demon’s chest and hid against him, feeling relieved when Dean hugged him,
wrapped a strong arm around his waist and pet Castiel’s hair soothingly.
“Shh, it’s gonna be ok baby, me and Sammy will help you out, make sure none of
the others hurt you at all.”
“R-really?”
“Sure baby boy, we just gotta mark you, it’ll mean your ours and they can’t
have you,” Dean explained his voice warm and reassuring. Castiel pulled away a
tiny bit so he could look up at the demon with timid curiosity.
“Mark?”
“Yeah, we’ll just mark you on the inside and out,” he told the angel, petting
his hair still and wiping Castiel’s tears away again.
“Will it hurt?”
“It might a little but it’ll be nothing compared to what the others will do to
you.”
Thinking of the librarian, of how casually they killed her, left to slowly die
on the floor Castiel believed Dean, this demon didn’t seem anything at all like
those ones had.
“I-If you can…please mark me,” he asked quietly, feeling scared of the pain it
might cause but desperate to avoid the other crueler demons. Dean made a
pleased sound and pressed Castiel closer, putting his finger under the angel’s
chin to tilt his head up. When the demon kissed him Castiel was confused. What
did that have to do with marking he wondered but then Dean opened his mouth up
and slid his tongue along the seem of Castiel’s lips, pressed to get in so the
boy let parted his mouth a little. The demon’s tongue felt too big in his
mouth, sliding in and touching all over, lapping at Castiel in a way that made
him feel weird. He could taste the faint tang of something when Dean rubbed
their tongues together and the angel wondered if that was how Dean would mark
him.
“You taste pure,” Dean muttered when he pulled back, his finger pulling at the
ties of Castiel’s robes. He lifted the angle and sat him on his lap more
properly, made him straddle his thighs. “You’re untouched aren’t you Cas?”
“I…I don’t understand,” the angle replied unsurely, watching as Dean eased his
robes open, his skin bared and the laces of his leggings revealed.
“Pure baby, you’re pure in body, have you ever fucked?” Dean asked and the
other demon, Sam scoffed.
“Mated Dean, he’ll know it has mating,” he said over a book and Castiel felt
his face flush red then as he shook his head furiously.
“N-no, I’ve never, I’m still a year too young to start courting,” Castiel
explained and Dean nodded with an accepting smile.
“It’s fine baby, just wanted to know, it means I’ll just have to mark you extra
good so no one knows, pure angels are real treats to demons,” he told the angel
and Castiel felt a shiver run through him, glancing at the closed door and
hoping no other demons would come.
Dean leaned forward in his seat but held Castiel so he didn’t fall from his
lap. He pressed his face into the crook of the angel’s delicate neck and gave a
sudden lick making the angel wiggle as it tickled him. He felt Dean smile and
the demon kept licking at him, lapping over his neck and chest.
“Taste sweet all over baby boy,” he praised and Castiel just watched as he slid
his tongue over Castiel’s flat nipple. The warm wet touch felt strange,
something tingling different from being tickled. The demon kept lapping over
it, sucking the nub into his mouth and nipping at it lightly, making the angel
start a bit as he rested hid hands on Dean’s shoulders. It felt kind of good,
in fact the more his nipple was suckled the better it felt he decided. He
didn’t understand why Dean was doing it, there was no milk in Castiel but he
stayed quiet and just watched, feeling the tingling in him get stronger.
Castiel was surprised when a little noise left his mouth without him meaning
too. He glanced up and saw that Sam was watching him, head bent curiously as he
watched the angle and it made Castiel shy.
Dean lifted them up, handling his weight easily as he walked to the table and
set Castiel down on it, laying him on his back as he pressed a last kiss to his
stomach before he pulled back. The angel stayed where the demon put him and
just watched as Dean undid his leggings and stripped them off him, leaving
Castiel bare.
The demon’s tail was slithering along Castiel’s foot, wrapping around his ankle
as Dean leaned down and kissed him again. The time it felt too warm, a new
sensation buzzing under Castiel’s skin as Dean licked the inside of his mouth.
He tugged Castiel to the edge of the table and the angel felt Dean’s body press
to his own, a bulge pressing to his thigh. When Dean broke the kiss the angel
cast his gaze down and saw the certain line of something in Dean’s leggings,
straining to be free. With wide eyes he watched Dean undo his pants and the
length of his member was freed. It stood straight up and bobbed against Dean’s
stomach, all red and sore looking. Castiel had never seen anything like it
before, his own member laying in the curls of his pubic hair not even half the
size of Deans. He’d never had it look like that either and he said so quietly,
making Dean laugh.
“Never? Your cock never stood all hard when you saw a pretty angel girl walk
by?” The demon asked lightly as his warm hand cupped Castiel’s member and
gently started to squeeze him. It felt strange, like when Dean sucked on his
nipple and the angel squirmed at the funny feeling.
“Shhh baby boy, I’m gonna show you all sorts of new stuff,” Dean chucked, his
tail sliding up Castiel’s bare thigh and pressing down somewhere lower then
Dean’s hand. The tip just rubbed along Castiel, making him squirm even more at
the feeling of it. The demon was stroking his member now, pulling at his length
in rhythmic motions and the angel watched as his own cock started to stand up
on it’s own. Castiel felt tingly all over, most of it pooling in his belly and
the in the places Dean was touching him. The demon kept doing it too, touching
Castiel and the feeling kept building up until it was suddenly over flowing,
spilling a consuming sensation all over the angel. Castiel’s wings spread out
wide and he whimpered, his waist moving strangely as he felt something
wonderful over take him.
By the time Castiel came to his senses Dean was pressing something wet and warm
along Castiel’s backside, right in the cleft and over the place where his tail
had been rubbing. The angel made a confused noise but didn’t protest as Dean’s
tail pressed back against him and then pushed up into his hole. It felt really
weird and the angel closed his thighs but the tail still worked up into him.
“It feels wrong,” Castiel whimpered, just knowing that putting something up
there was a dirty thing to do, dirty and bad.
“S’ok Cas, sweetheart you’re just new to it, let me find it…” the demon trialed
off and Castiel peered up at him, opening his mouth to ask when Dean meant but
then the tail pressed something inside him and it felt like that wonderful
feeling all over again, drawing a gasp from his lips.
“See? Told ya baby, little angel like you doesn’t know these things but I’ll
show you,” Dean coaxed, smiling as he dropped a kiss to Castiel’s head and
pried his thighs open again. Nervously Castiel let him and lay back against the
table, watching Dean look down between his legs with fascination. Castiel could
feel the tail in him moving around and he didn’t know what to think, was this
part of marking?
“Here, sit up for me,” Dean suddenly instructed and the angel struggled to
obey, it was awkward to sit on the edge of the table with a tail in him so Dean
put him on the floor, kneeling on the stone as Dean’s big member bobbed in his
face.
“Do me a favor baby, I need you to give it a lick alright?”
Castiel didn’t understand but he nodded and bit his lip, staring at the thick
length before he timidly leaned forward and gave the tip a quick lap. Something
white came out immediately and the tail in him shifted, making Castiel’s wings
flutter nervously.
“Good boy, that was perfect, you need to get more of that out of me, that’s
what I’m gonna mark you with, need to mark you with my come,” Dean explained
and Castiel rubbed his tongue with his finger so he could look at the white
smears. It was milky looking and tasted salty, Castiel wondered how it would
keep the other demons at bay.
“Angel’s don’t have this,” he told the demon, looking up at him from his place
on his knees and Dean gave a huff of a laugh and ruffled his hair.
“Cas, you silly thing, you already showed me you do, when you came that came
out, I used it to make you slick so my tail would go it.”
Castiel blinked up at the demon for a moment before reaching between his legs,
feeling the tail in him wiggle a bit as he tentatively touched around it and
felt something slick there. The tail came free and the angel could see the
white smears on it as it rubbed along his belly, pressing against his own soft
member. Castiel touched a gob of the white and stared at the smear with huge
eyes.
“This came from me?”
“Sammy what do angel’s call come?”
“…seed I imagine,” the other demon replied and Castiel suddenly understood. He
knew a little about mating from whispered conversations, males gave their seed
to create children in female. To give it to other males must be a way to mark
them, at least in demon’s eyes.
“I’ll show you later baby, show you how to spill your ‘seed’, but hurry up and
get some from me, you need to do it good or you won’t get enough to keep the
others away.” Dean warned as his hand cupper Castiel’s head and pulled him
closer to Dean’s cock. 
The reminder was all the angel needed and Castiel lifted his lips to lick at
the tip of Dean’s cock, sucking more gobs of white from it. The demon gave a
low groan and rubbed himself along Castiel’s lips.
“S-should I swallow it?”
“Some of it, let some run down your chin too, get it on your skin sweetheart,
gotta mark you on the inside and out” Dean replied, pressing his member along
Castiel’s face to show him, a smear of white coming out along his cheek as Dean
rubbed it against his skin.
“Try to put more in your mouth, the more you put in the more you can suck, suck
really good for me Cas.”
The angel gave a nod and opened his mouth again, holding the thick cock in his
hand as he pushed the entire head into his mouth. It was huge and he had to
open his mouth really wide but it fit and Castiel pressed it in more, trying to
suckle at as he was instructed.  
“Fuck, you sure you’re an innocent thing? Seems like you’re a natural at this,
look perfect with a cock in your mouth baby,” Dean said with a grunt, his hips
moving so the head rubbed along Castiel’s tongue. He looked up at Dean,
watching the demon grin down at him, he wasn’t sure what Dean meant but he did
understand it was a praise.
“Want you to keep doing that, suck nice and hard for me while I push in a
little more, gonna ride your mouth. Keep those teeth away too, don’t wanna bite
me by accident.”
Castiel had no idea how Dean could ride his mouth, it made no sense but he just
kept doing what he was and let the demon’s hands in his hair guide him while he
was careful of his teeth. Dean’s hips starting moving again, nudging forward
and Castiel felt the cock on his tongue slide in deeper. It seemed impossible
as more and more of the huge length disappeared into his tiny mouth.
“Fucking hell, how the hell, where are you putting that,” Dean muttered but
pressed on and Castiel just kept sucking, watching Dean’s cock feed into his
lips until there was none left, his mouth pressed right up to Dean’s groin. The
demon slid back then all the way out as he peered down at Castiel.
“You could breath ok?” He asked like it couldn’t be true but Castiel nodded, it
felt a little tight but he didn’t have any problem getting air in.
“Sammy, you gotta see this,” Dean called his sibling and he turned back to
Castiel, cupping his head and pushing his cock back into Castiel’s mouth. He
shoved in deep faster this time, Dean pulling back and thrusting in over and
over. For a moment it confused Castiel but then he remembered that Dean had
moved hand in such a rhythm when he touched Castiel earlier and coaxed the…Dean
called it ‘come’ out of him. The angel kind of understood what the demon meant
by riding then.
Dean seemed astounded that Castiel could put it in so deep and the angel agreed
silently, he had no idea how he was able to take it so far, he could feel it
tickling the back of his throat and everything. But if he breathed in through
his nose when Dean pulled back he felt fine, trying to suck as Dean instructed
of him.
“Fuck, Alright baby boy, gonna give you what you wanted, sucked it right out of
me,” the demon suddenly groaned and his hips jabbed harder, grinding at Castiel
face for a moment before he felt the cock in his twitch hard. Then Dean was
sliding back, leaving spurts on Castiel’s tongue as he pulled it form his mouth
and took himself in his hand, pumping it like he had Castiel’s but much faster.
The angel watched with rapt attention as the tip of the cock erupted with
white, seed spilling over and spurt onto his face, warm gobs on his skin.
Castiel remembered the marking then and he pressed in closer rubbing his cheek
along the head to get it on his skin, Dean gave a grunt and stared down at him
through lidded eyes a strange expression on his face as he marked the grateful
angel. When Dean’s hand slowed the spurting did as well and Castiel watched it
slowly come to a stop. When the demon stepped back Castiel looked down and saw
white lines dribbling down his bare chest.
“Should I get it all over?” He asked and Dean gave a low sound in reply,
running a hand through his hair and turning to his brother without answering.
“Sammy, get your ass over here and face fuck this angel, he got no bloody gag
reflex.”
Castiel didn’t know what that meant but he sat on his heels and peered meekly
at the other demon, the more marking the more better he figured, looking at the
demon’s crotch and seeing his cock pressing against his leggings.
“Hurry up,” Dean said again and the other demon gave a huff but put his book
aside and came over to them, undoing his leggings. Sam was bigger then Dean,
taller and more broad. His cock was bigger too, longer Castiel thought as he
parted his lips and let the demon push it into him mouth.
“See, fucking cock slut for certain. Ever see an angel swallow it down the
easy?” Dean asked and his brother gave a grunt in reply. His hands where in
Castiel’s hair and he held on a little tighter, shoving a little faster then
Dean but the angel adjusted himself and did his best.
“Doesn’t know how to suck very well,” Sam muttered and Castiel tried right away
to do it harder. “Move your tongue, rub it along my dick,” the demon
instructed, his hand cupping the back of Castiel’s skull and pulling him up a
little higher. The angel did as asked and Sam gave a low noise, hips pumping
quick.     
“Told you,” Dean sounded smug as he stepped behind Castiel and knelt on the
floor with him. “With a little training he could be a real pro,” the demon
muttered, his hands moving Castiel to kneel up higher and spread his thighs. He
wanted to look back and see what Dean was doing but Sam had a good grip on his
hair and the angel wanted his seed, he wanted to be safe from the other demons.
He felt it when the cock twitched like Dean’s had, Sam shoving really roughly
now as Dean’s tail wiggled back into Castiel’s bottom again. Warmth filled his
mouth suddenly but Sam didn’t pull away, just kept shoving so the angel
swallowed it down, lots of it still over flowing his mouth and running out the
corners of his lips. When a steady flow of seed kept filling his throat there
was no room to get any air in and after a bit Castiel struggled to pull back.
Sam’s hand held him there for a moment longer before he let go and the angel
yanked off his memeber, sucking a deep breath as the last few spurt of Sam’s
cock slapped onto his chest.
“Good boy, Cas, did real good there baby, didn’t he Sammy?”
Castiel looked up at the demon, licking the stray dribble of come from the
corners of his mouth. Sam looked down at him for a moment, examining him
critically and the angel was relieved when the demon gave a softer smile and
ruffled his hair a bit.
“Yeah, he did great,” Sam agreed.
“We’re just gonna numb you a bit baby, make it easier for you,” Dean announced
and Castiel watched as Dean spat into his hand, the spit bubbling a bit in a
weird way.
“Too much,” Sam said and Dean grunted but wiped his hand on the rug a little,
leaving only a little spit.
“What’s that?” Castiel asked, concerned when Dean rubbed it over the angel’s
backside, smearing it all over his hole down there.
“Venom, just a tiny bit though, it’ll numb you so it won’t hurt,” Sam explained
and Castiel blinked up at him, he never knew demon’s had venom and he said so.
“Most don’t, it’s a Winchester thing, we can use it as we please and it won’t
hurt you since it only induce low level paralysis,” was Sam’s calm explanation,
he attention on the way Dean was kneeling closer to Castiel pushing him down to
his hands and knees as his tail came free. The demon reached under Castiel and
ran his fingers through the come on his chest, gathering it up to smear around
him down there again.
“Might burn a little, but try and take it Cas, we need to mark you inside here
too,” the demon coaxed and the angel gave a little nod, his wings trembling
slightly as he felt Dean pressing something up against his hole, something much
wider then his tail. It did hurt a tad but mostly Castiel just felt tingly, his
body feeling numb down there from the venom as Dean pulled him back into his
lap slowly. The angel felt full in a strange way and as Dean pulled back and
gave a little shove again he realized the demon had put his cock inside him.   
“I never knew…this is mating isn’t it?” Castiel asked, knowing now why Dean
asked about it earlier. The demon gave a nod and pressed the angel back,
showing him how to rock back and forth.
“Fucking hell, that’s obscene, his little hole’s stretched so hard, barely
fitting it in there,” Dean muttered, staring down at the place where he was
buried in the angel. That place inside where Dean’s tail had touched earlier
kept getting rubbed and Castiel gave a weak gasp at the feeling.
“Show you what a little cock slut you are, fuck. This ass is meant to be
fucked, just like that cute little face of yours is meant to be painted in
come. Didn’t I say I’d show you your own too? ” the demon said and suddenly
Castiel felt his big arm wind around his skinny waist, lifting the angel into
his lap as his tail wound around Castiel’s cock. The small length was standing
right up like Dean’s did and it looked swollen and sore too but it felt good,
it didn’t hurt at all. The angel peered down at himself with something like
wonder as Dean’s tail moved over him and made everything feel better. The cock
inside him helped make it better, Dean lifting him on his lap and bouncing the
angel so his member moved back and forth in him. The friction rubbed that spot
and it made Castiel give a surprised sound, grabbing at Dean’s arm and holding
on tightly as he felt that feeling building up again, the good staring to jump
higher then anything Castiel had ever known.
“Watch Cas,” Sam said and the angel blinked, looking down at his own cock and
watching as the white spilled, seed coming from his own body as Dean pumped
into him. Castiel felt strange, it felt so good but he was out of breath now,
even though he hadn’t done anything. Dean pushed him forward roughly though,
making the angle get on his hands and knees and Dean yanked Castiel into each
shove of his with more urgency. 
“Sit in the chair,” Sam suddenly said and both Castiel and Dean looked up at
him.
“What? Why?” Dean grumbled but pulled free form Castiel and got off the floor.
He sat down in the chair and before the angel could follow Sam scooped him up,
settling Castiel in Dean’s lap facing the demon. The angle reached down and
took Dean’s member to pressing it back into him and Dean gave him a big grin
for doing it without being asked. Castiel rest his hands on Dean’s full chest,
feeling his big hands on his hips as Castiel moved up and down again.
Sam stepped up behind them and Castiel blinked, looking up at him curiously as
the demon tugged Castiel’s wings in, tucking them closed and pressing them
together.  The angel pulled them in as snug as he could obediently and felt
something touch along his back, right between his shoulder blades.
“Sammy you perv,” Dean laughed and the angel didn’t understand at all, blinking
at Dean but still bouncing himself up and down. Sam made a sound and pressed
his hips into Castiel’s back, hips rolling. The angle realized then that the
demon had his cock pressed between his wings, Sam was thrusting into the
feathers and the tip was rubbing along his skin, along his spine.
“Is he going to mark me there?” Castiel asked and Dean chuckled and nodded his
head.
 “Yeah sweet heart, he’s gonna give you a nice heaping load all over those
feathers of yours.” The idea of it sat well with the angel, if his wings were
marked then maybe other demons wouldn’t try to tear them off.
Dean’s started moving faster, his tail squirming over Castiel’s cock while he
pumped into the angel with rough shoves. His hands cupped Castiel’s behind and
squeezed it, pushing him down to meet his pounding thrusts as the demon
grunted. The place inside Castiel was tingling again and he squirmed a bit but
the demons he was between held him in place.
Something flicked in his face and Castiel blinked, watching the tail tip move
along his face and press at his lips. Dean’s tail was still wrapped around
Castiel’s member so it had to have been Sam’s tail. The angel looked up,
blinking at the other demon as Sam looked down at him with a strange
expression, like he wanted something from him real bad.
“Suck on it,” Sam said and Castiel did so, parting his lips and letting Sam
feed it in his mouth before he closed his lips and sucked on it like he did
with their cocks.
“Fuck, yeah baby boy, sucking it down, taking it like a greedy slut,” Dean
muttered, watching as Castiel suckled the tail and bounced on his lap. “Damn,
I’m gonna-” The demon cut off, suddenly slamming really hard into Castiel,
pressing him down as he made a rough noise and jabbed in short tight shoves.
Dean hissed out and Castiel felt the cock in him twitching, that pulse that was
becoming familiar was telling him Dean was marking him on the inside. When Dean
slumped against the chair Castiel gave a sudden cry as Sam’s tail pulled out
and the demon lifted him right off Dean’s lap and put him on the floor. Castiel
ended up bent over Dean’s lap with Sam pressing into him right away. The demon
slammed really rough, yanking Castiel back and forth as he pounded him harshly.
It hurt a little but the place inside the angel liked it, Sam was moving over
that place so quickly, his cock rubbing it just right as Castiel gasped out and
his hands clutched at Dean’s thighs. The demon just laid back and watched
Castiel as the angel whimpered a little and felt the good feeling coming over
him again, riding up to consume him. Sam rode him through it, grunting as
Castiel shivered and dropped his head to watch the white seed come from him
body. It fell to the floor in a splatter.
The angel gave a cry when his head was yanked back up, Dean’s fingers rough now
as he looked down at Castiel and pulled at his own cock lazily.
“Suck it down again,” the demon said and shoved the head to Castiel’s mouth. He
obeyed and this time Dean pumped into his mouth just as hard as Sam, both
moving roughly as the manhandled the smaller angel who was helpless to do
anything. It hurt more and more, Castiel’s jaw getting sore now and his hips
hurting from where Sam was digging his fingers. Thankfully the demon riding his
behind suddenly stopped with a deep gasp, pressing himself all the way into
Castiel and muttering as the angel felt the warmth deep inside him. But then
Sam pulled free and spurted the rest on Castiel’s wings, the white splattering
onto his trembling feathers.
Dean took longer, the angel had to wait until he was hard again before he came,
pulling out to smear it good on Castiel’s face before he let the angel slump
back to the floor, feeling really tired as he laid on the carpet and watched
Sam go thought the books again. There was come all over him now, all on his
face and chest, smeared all over his thighs as the seed inside him kept
dribbling out.  
“What ya think Sammy?” Dean asked after they both caught their breath again and
Castiel looked up at him, fear making him freeze when he saw Dean had a knife
in his hand and was looking right at him, not seeming kind at all anymore.
“He’s got talent, with some training he could be damn good, I think I might
know a few spells to keep him small like that too.”
Castiel’s wing shook hard as his tears started to fall, he looked up at Dean
silently begging as the demon looked back at him calmly. The angel felt stupid
now, for thinking that these two demons were nice, that they wouldn’t hurt him.
 
“You have a choice little angel, we can leave you hear safe and sound in this
room to hide but you’d be all alone, there’s no angles left alive in this place
and most of it is burning down as we speak. Plus who knows when others will
come, could be months,” Dean explained and Castiel shivered, hugging himself as
he looked down, knowing it was true, until a massager came and saw the
sanctuary was attacked no one would realize. With the winter storms it could be
longer then months before the winds were calm enough to allow travel for anyone
to come.
“Or,” the demon paused until Castiel looked back up at him. “You can come with
me and Sammy, be a good little whore for us, sucking and fucking as we please.
We’ll take care of you, keep you safe and fed, hell we even have tons of books
thanks to him,” Dean made a gesture at his brother but Castiel kept his gaze on
him, on the demon with the knife.
“What’ya think baby boy?” The demon asked and Castiel watched the blade as Dean
casually swung in around his fingers, easily moving it without nicking himself.
The angel didn’t know what a whore was, but he understood what they had just
done was ‘fucking and sucking’.
“If I stay will you hurt me?” He finally made himself ask and the knife in
Dean’s fingers paused.
“Nah, baby, we won’t hurt you at all, just leave you hear to the cold, the
fires will die you know.” There was a fireplace in the small room and it’s
flames were what kept the room warm but once it died the winter’s cold would
seep in for certain. But Castiel wasn’t thinking on that.
“T-then why do you have that?” The angel whispered fearfully and Dean grinned
like he was waiting for that question all along.
“Cause if we take you with us we’re gonna need to give you a little mark, just
a few nicks on your chest. The seed on you will keep the others away for now,
but once it’s washed off you’ll be free game again. So I’ll just put a little
something on you that will be permanent.”
“…will it hurt?”
“Baby, for a pretty angel boy like you I’ll even use a little venom to numb
your skin.”
Castiel looked at the demon quietly, not as scared anymore now that he knew
Dean didn’t intent to kill him but still nervous. What the demon was saying
made sense, it was logical for Castiel to go with them but something in him was
warning him, hesitating. These were demons his mind recalled, the sight of the
weapon a jarring reminder. But then the Sanctuary was full of them and at least
these two seemed to like him. 
“Do…do you want me to go?” he questioned quietly and Dean’s look softened a
little, he gestured for the angel to come to him and after a moment Castiel
obeyed, crawling right into his lap and cuddling close. It wasn’t a wise think
to do but the angel didn’t have many options and if Dean would let him he
wanted to cling tightly to someone.
“It’s been awhile since we had ourselves a sweet little consort, it’ll be nice
not to have to worry about getting shanked during a fuck,” Dean explained and
Castiel didn’t understand most of it but he did get that the demon was saying
he wanted Castiel.
“P-please don’t make it hurt too bad.”
 
When they left Castiel clung to Dean’s arm, wide eyed and terrified of the
other demons. He had been instructed to stay between Dean and Sam and he obeyed
utterly not letting go of Dean for a second. They promised to find him
something to wear soon but for now he needed to be bare so the demons could see
all the marking they put on him. Come dripping down his pale skin and crimson
lines in his chest now. Demons all over leered at him but none of them came
close to him, thier hungry eyes would leave him and fall on Dean and Sam before
turning away. The presense of the two stopping any of the demons from hurting
Castiel, he was certain of it.
A pained gasp caught his attention and Castiel turned to see another angel, the
first one he’d see since they left the consecrated room. It was one of the
elders with his wings pinned to his back and heavy manacles around his wrists
and ankles. The old balding man was staring at Castiel and the younger angel
pressed closer to Dean, not liking the look in the other angel’s face,
somewhere between anger and tears.
“They won’t be too nice to you anymore, not now that you’re a demon’s consort,”
Sam explained easily and ruffled Castiel’s hair lightly. The angel glanced back
at the elder, wondering what he thought of Castiel smeared all over with seed
and dripping blood from the markings carved in his chest. Dean said the numbing
would wear off but by then they could put some balm on the shallow cuts.
“Why do you have him? Is he a consort too?”
Both demons gave a chuckle and Sam shook his head, dropping his hand to the
back of Castiel’s neck and leaving it there, the weight comforting with so many
demons watching him.
“Nah, he’s an informant now, gonna send him ahead to find the right Sanctuary
that slimy bastard Zachariah’s holed up in,” Dean explained and Castiel blinked
up at him, the angel making a sudden noise and looking at Castiel with warning.
“Cas?” Dean asked, a curious note in his tone as they stopped walking and both
demons looked down at him. The angel’s wing gave a shiver and he glanced over
at the elder, seeing him shake his head once in negative before Sam moved and
blocked him from Castiel’s view. He heard a sharp pained sound and knew someone
had hurt the other angel.
“Do you know something about the angel Zachariah?” Sam asked, shifting the
books he’d taken form the library so he could peer down at Castiel curiously.
“I…” Castiel hesitated and Dean's hands closed on his shoulders, not hurting or
intimataing but rather comforting as they gave him a reassuring squeeze.
“Part of being our consort means being helpful, not just with sex but other
things, one day you might be able to help Sam with his research, but right now
if you know something about this you have to say so, me and Sammy have been
tasked with finding him. The sooner we do the sooner we can go home, and trust
me we wanna go home and get out this freezing cold weather, don’t you?”  
“I…I hide in the library lots, sometimes I overhear things…” the angel admitted
and he stopped when he heard the elder try to say something but his words were
cut off abruptly with another hard pained sound and a thump of the angel
falling or being forced to the floor painfully. Sam was blocking the way for
Castiel to see him but the angel knew the elder would be angry, that his words
would be treason.
But then this wasn’t his home anymore.
Castiel’s new home was carved into his chest.
“There’s a place in the woods north of here, smaller then the Sanctuary and
hidden by magic, master Zachariah stayed there, he came last week but I don’t
know if he’s still there.”
It only felt a little wrong when Sam and Dean smiled so happy, praising him for
being a good boy. Castiel knew then that their opinion would matter more then
anything else, if he was going to be a consort he was going to do it as best as
he could, even if he wasn’t quite sure what it was.
