Summary: The continuation of “Companion”, at long last. It
was supposed to be marathon sex, but my muse refused. I am ashamed. ;~;
------
Angels do not need to sleep. They
have beds, yes, but they rarely sleep in them. It’s just the way they were
created. Some do enjoy the comforts of laying down and resting from time to
time, but they hardly call that sleep. It was just... resting.
Castiel was one of the few angels
who actually liked to sleep. He’d gotten himself a large bed for exactly that
reason, so that he could stretch himself out and rest his wings on the soft,
thick mattress while he slumbered. He wasn’t doing much sleeping of late, but
at least he had the bed there for whenever he needed it.
“Cas,” Dean whined; arching his body and baring his throat to the
angel. His wings were flared out beneath him, curled forward in invitation, and
his all-green eyes were hooded and full of need. It was the most erotic sight
Castiel had ever seen, and it was a sight that was for his eyes only now. He
reveled in that fact as he ran his fingers over flushed, fevered skin; bent his
head to lick up sweat that beaded to the surface and paused to suck at one of
his mate’s peaked nipples.
The dragon demon let out a bass
rumble, and Castiel could feel the thighs on either side of him spasm and twitch
as the muscles jumped. Dean was trying to get lose of the bindings, but they
were specifically warded so that there was no way he could. Castiel could see
how much that frustrated his mate, because Dean was still in heat and the urge
to copulate was overwhelming his other senses.
“Patience, Dean. You know good
things come to those who wait.” They’d been at it for nearly three days now,
and even if angels didn’t have a refractory period, that didn’t mean that
Castiel didn’t like to take little breaks to just explore Dean’s body. The
demon was breathtakingly beautiful, and it was incredibly arousing to watch how
worked up he would get when he needed.
Dean wriggled against the sheets,
his wings twitching and shifting as his body opened before Castiel, trying to
tempt the angel and draw him closer. No matter their bond, or perhaps even
because of it, Dean was a demon first and foremost, and it was in his nature
and the sexual appeal that rolled off of him to twist and tempt pure souls.
True, he had been untouched when Castiel had bought him, but that appeal and
charm was still there, and Castiel was unashamed to admit that he had been
snared in the dragon demon’s trap. He couldn’t bring himself to mind, though.
Not when it got him this.
Bending over the body beneath him,
he mouthed his way up Dean’s throat. His mate keened softly, eagerly, and
tilted his head back to give the angel more room to work. Castiel planted a
trail of sucking bites up that bronzed path of skin; nipped along Dean’s jaw
and chin and planted butterfly kisses across his cheek until reaching the
demon’s swollen, kiss-abused lips. Dean opened his mouth immediately, but
Castiel chose to flick his tongue over the demon’s bottom lip rather than just
claiming his mate’s mouth again. There was a raw sensuality to the act, but
also a fair bit of teasing, because he could see how much Dean wanted it, and
the fact that he was denying him made the other creature growl and try to
initiate a kiss.
They did kiss, eventually, and
Dean’s mouth was so hot and sweet. He tasted of many things, and the flavors
were so addicting that Castiel pressed down against his mate and covered him
with his body and wings. There was nothing violent and taking about the kiss,
and Castiel didn’t try to dominate Dean’s mouth like he had several times
previously. It was a passionate kiss, and one Dean returned eagerly. His mate
was so welcoming to him, and when Castiel nudged his hips forward he felt how
open and wet Dean still was.
Something was mumbled against his
lips, so he pulled back and looked down at Dean. “What did you say?”
“I said do it.” Dean tilted his
hips in invitation; lifted his head so that he could stare down his body, past
his own swollen need that was fitted with a cock ring, to stare at where
Castiel was close to breaching his body yet again. They had mated so many
times, and yet Dean was still wet and ready to be taken yet again. Not only
that, but as Castiel thrust into the demon’s body, he felt how tight Dean still was, and he let out a
soft huff of breath while Dean moaned loudly.
“You’re so beautiful, Dean.”
Castiel rocked his hips against Dean for a while, just feeling the heat and
tightness around his erection and giving little jerking thrusts every time
Dean’s body tightened around him. It was exquisite.
“C’mon, Cas, just fuck me,” his
mate groaned. The scent of Dean’s pheromones filled the air, a sweet, addicting
scent that made Castiel just want to bow his head and lose control, but he was
determined not to. It had been like that nearly every other time, and this time
he wanted something different.
“There is no sin sweeter,” the
angel whispered, leaning down to place fluttering kisses across Dean’s lips,
“no feeling more great, than hearing you call my name and knowing that you are
mine.” He finally kissed Dean, curling his tongue across his mate’s as he
pulled his hips back and then thrust into the body beneath him again.
Dean shuddered beneath him; moaned
into Castiel’s mouth and tried to arch and rub his body against the angel’s.
Castiel let him, knowing that with his hands and feet bound it was the only
kind of relief he could give himself. It was an arousing feeling, having Dean
rut shamelessly against his stomach while Castiel thrust against him. He knew
when he found his mate’s prostate, because Dean choked on a lusty roar and
tossed his head to the side so Castiel wasn’t singed by the tongue of flame
that flicked out of his mouth.
“Such a good boy,” he praised,
rubbing his nose along the hinge of his mate’s jaw as he rolled his hips and
pressed up against the gland that made Dean’s entire world shake. “My sweetest
sin; my greatest pride. My love, and my life; the one whom I will share
everything with from now until the end of eternity.”
“Cas, please; Master, I need more.”
Smoke trickled out of the corner of Dean’s mouth, and his mate’s eyes were shut
tightly as he tugged at his restraints. He wanted nothing more than to touch,
it seemed, and his struggle to do so was as curious as it was arousing. Castiel
had never realized that he would enjoy seeing another bound beneath him so
much, needing so badly but unable to touch. That it was Dean, well, it was an
image that the angel would never get tired of seeing. His mate was headstrong,
and he had a temper, but like this- wrapped in the primal need and heat of his
mating cycle- he was wanting and pliant. It was the greatest high Castiel had
ever achieved.
“You have gotten plenty your way,”
Castiel breathed against Dean’s neck, feeling how that one little touch made
his Companion shiver and tremble with desire. “You have asked for hard and
fast, and I have given it to you. Now, though, it is my turn to set the pace,
and you will follow me.”
Slipping a hand beneath his mate,
Castiel pulled him up slightly and continued to rock in and out of his body at
a slow, steady pace. He stimulated Dean’s prostate with every thrust, giving
his mate some of the pleasure he sought but never going hard and fast like Dean
wanted him to. The dragon demon was trying to seduce him into getting his way,
twisting his body and letting his muscles ripple beneath his golden skin as he
stared up at Castiel with black, needy eyes.
The longer it went on, the stronger
Dean’s pheromones became. His mate was so wound up, his body craving release
and to be filled, that he was shaking himself apart in so many directions. With
each passing moment that his orgasm was denied, his scent became stronger, and
Castiel, an angel who prided himself on restraint, was losing his grip on the
situation. All he wanted to do was bury himself in Dean and fuck him fast and
rough as his mate and his body begged him to do.
Castiel pulled out almost all the
way before stopping; left the head of his dick just inside of Dean so that his
mate could feel him there but could get no real pleasure from it. He stared down
at the creature below him, and his Companion stared back up at him, mouth open
as he panted and the tips of his fangs flashing with each heaving breath. The
angel bit his lip hard, and the sight caused Dean’s scent to spike even higher,
shattering the last few clinging strains of Castiel’s restraint.
Dean roared when the angel slammed
back into him, his body arching up and his muscles twitching in little spasms
as Castiel ran a hand over the body beneath him. His long, pale fingers curled
around his mate’s neglected cock. It was hot and pulsing in his hands, the dark
flush almost worrying because of how long the cock ring had been holding Dean’s
orgasms at bay.
“Do you want release, Dean?”
“Yes, please, Master. I want to
cum; please let me cum!” Dean was shameless with his begging, bucking up into
Castiel’s hand and jerking with every powerful thrust. It drove Castiel insane,
how incredibly alluring his Companion was; how good it felt to be touching him,
and how possessive he felt with each rough slam into the demon’s body. A litany
of mine, mine, mine, mine echoed in
his skull for every thrust, and he didn’t even realize he was muttering it
against the sweaty skin of Dean’s neck.
The cock ring came off quickly, and
Castiel rubbed a finger over the skin it had pressed against, drawing a keening
cry from his mate. Dean’s body seized up against him, and then the demon was
cumming. It coated Castiel’s fingers with slick heat and filled the air with
another scent that drove the angel crazy. When Dean was finally spent, he
lifted his hand to his Companion’s mouth and let him lick and suck on the
cum-covered fingers until they were clean and wet with only saliva.
Dean would do anything he asked
him, or told him, and that sense of power was one of the greatest things
Castiel had ever experienced. The Seraph had never been one to give orders to
anyone, and with Dean it wasn’t really giving orders as much as it was
requesting that Dean do something he already didn’t mind doing. Castiel would
never take advantage of his mate like that, because Dean was in his care and it
was his job to make him happy; just as it was Dean’s job to assure that his
Master was content, but even if they did nothing but fight Castiel would be
content. At least he wasn’t alone then.
His thoughts stole away as Dean’s
internal walls tightened around him to the point where Castiel couldn’t move
and it was almost painful. The angel moaned quietly and waited for his mate’s
body to relax before he pulled back and sat on his haunches. A wave of his hand
freed the demon’s wrists and ankles, and Dean was more than willing to crawl
onto his lap and let Castiel position him before he thrust back up into his
mate’s body.
“Feels so good, Master,” Dean
moaned against his collarbone. Castiel pet a hand down his Companion’s back as
he continued to rock up into him with powerful thrusts. Every time he nailed
the creature’s prostate, Dean would moan eagerly and buck against him. The
demon’s cock was already filling again, his need to mate still strong and
compelling. “You feel so good.”
“So do you.” Castiel pressed a kiss
against Dean’s temple; coaxed his head up so they could kiss properly. Dean
opened up eagerly for him, letting the Seraph’s tongue curl over and around his
before sucking on it and drawing a ragged moan from Castiel. He was so close, and
Dean was so innocently affectionate like this- as eager as a fledgeling and
willing to please. Like this, there was no hot-headed battles and bullish
attitude. Dean wanted him, and he wanted Dean, and they were free to share
their love and affection as mates did. Dean wanted pleasure, and he wanted to
give Castiel pleasure as well. The angel liked that.
He liked that, and he loved Dean.
The Seraph moaned low in his throat after one particularly long suck on his
tongue and pressed his hand against Dean’s lower back. The demon shifted
obediently on his lap and spread his legs wider; sinking down further than
Castiel had thought possible and moaning into the angel’s mouth. His wings
flared out behind him, arching up high, and Castiel lifted his own wings to
press them against his mate’s in an act that was far more loving and gentle
than the wild fucking they had been doing for so long.
It was that, more than anything,
which finally made Castiel crest high on his wave of pleasure and reach his
peak. He came in shuddering twitches that rocked his whole body, and he felt
more wetness streak over his stomach in hot, wet lines as Dean came again as
well, the demon’s body so sensitive and tuned into his mate’s own arousal that
Castiel’s orgasm triggered his own.
Castiel sucked in deep breaths, his
nose tucked under Dean’s ear while the dragon demon nuzzled and licked at his
throat. When he felt like he was recovered enough, he pulled back and laid Dean
down before curling around his mate and rubbing his fingers over the creature’s
wings. It was so odd to touch the leathery membranes, so different from his own
soft feathers, but it was a pleasing feeling rather than a disgusting one.
Dean hummed in delight while
Castiel pet his wings, and Castiel watched him sink back against the pillows
and make himself comfortable. The scent of his Companion’s heat was finally
beginning to abate, it seemed, if only for now. Dean was obviously satisfied,
and probably more than a little sore after being taken roughly so many times,
but the demon wasn’t complaining. In fact, he had a blissful expression on his
face as Castiel let his fingers explore from membrane to scale, feeling out the
obvious differences and being careful not to stroke the wrong way lest he cut
himself.
“So gorgeous,” the Seraph breathed,
looking down at his mate. Dean watched him with drowsy eyes, but a crooked
smile curled at the corner of his lips. It was an adorable little smile, and it
lit up his face in a way that made him seem more like a mischievous younger
angel than a bloodthirsty demon.
“You ain’t so bad looking
yourself,” Dean replied; rolling his body in a stretch and extending his wing
further as Castiel continued to explore it. “Hey, not to break this whole
chick-flick moment of whatever, but can we take a shower? I don’t think we’ve
showered yet, and to be frank I feel kind of gross right now.”
Castiel laughed before he could
stop himself. Somehow, it didn’t surprise him that Dean would be uncomfortable
with soft, affectionate moments like this, but he wasn’t complaining. It was
part of the demon’s charm, honestly, and he wouldn’t change that about his mate
for anything.
“Yes, Dean, we can take a shower.
It’s big enough to fit the both of us, so you won’t have to worry about not
having enough room.” It was lucky Castiel pulled back when he did, because Dean
let out a happy whoop and then scrambled off the bed. If Castiel hadn’t moved
back, he would have been smacked in the face by a wing.
Dean sniffed out the bathroom on
his own, and Castiel followed leisurely behind him. A shower would be nice, and
he could wash Dean for the first time; most certainly not the last. His mate’s
pheromones were already starting to get stronger again, so perhaps they could
try their first round of shower sex as well.
“Are you coming or what,
Featherhead?” Dean was staring at him from inside the bathroom, using his bulk
to block the door.
Laughing, Castiel gently pushed
Dean out of the way so that he could get into the room as well; folded his
wings against his back and went to turn the shower on and adjust it to a heat
they would both be comfortable with. While they were there, he could groom
Dean’s wings, too. His mate may not have feathers, but he could only imagine
that his Companion’s wings needed some kind of special care as well. Castiel
could use his own oil on them, which would be just as claiming as it would be
sensual.
The water was hot enough at last,
and Dean stepped in and immediately pressed himself up against the Seraph’s
body. His green eyes were getting dark again, and as Castiel watched he licked
his lips.
“Want to go again, while we’re
here?”
Castiel grinned. “I would like
nothing more than to have you as many times as I can, my sweetest sin.”
