****** My Kitten ******

Summary
     Sebastian's kitten, Ciel, is 'a little' needy
Notes
     This fic came out of nowhere, but I have a deep spiritual connection
     to Ciel and, well, cats, so you know...
     I'm sorry!
    Ciel sat impatiently watching Sebastian gently place the saucer of milk and
honey on the floor, supple dark blue tail swaying enthusiastically behind him.
As soon as the saucer touched the ground, Ciel leaped forward, bringing his
hands in line with his chest against the floor, leaving his pert ass in the
air, tail swinging more joyfully against the soft exposed skin of its naked
owner. Sebastian smiled while watching his kitten hungrily lap at the milk and
bending down to pet his smooth arched back, "what a greedy little kitten, be
sure to clean the saucer, I don't want to see any cream in it or on you". Ciel
hummed, messily drinking the milk, tongue working fervently to get as much as
possible in his mouth; Sebastian patted the kitten on the back before walking
back towards his desk.
    The kit could hear his master working away, as usual, choosing 'work' over
his kitten (usually leading to disaster as Ciel did no play well alone, least
of all with the furniture), but was too content with his treat to bother him
just yet. The moment Sebastian began getting in the groove of working through
the new client's account history, a certain kitten jumped onto his lap, still
cleaning himself off of the cream he got on himself. Ciel began to purr and
nuzzle the man's chest, stretching as far as he could to reach his master's
collarbone, ears perked up and brushing softly on his master's face. While
endearing, Sebastian had work to be done and had already indulged the boy
today, "not now, kitten. Master is trying to work, we can play once I have
finished". Ciel huffed a bit before continuing, leaning up onto Sebastian's
chest and kneading the fabric of his vest, "but I want to play now, master, pay
attention to me!". The kitten nosed the sensitive skin under his master's ear,
knowing how to turn him on, canting his hips so his growing hard on smeared the
front of Sebastian's clothes. Sebastian felt his pants growing tighter as Ciel
kissed and licked his neck, giving special attention to his pulse point and
behind his ear, the tip of his little cock rubbing against the harsh fabric of
his clothes causing the boy to make obscene breathy moans, but was determined
to finish his work- if he gave in every time his young kit wanted to 'play' he
would have to reconsider what his title as 'master' meant.
    Sebastian sighed and picked up the small form and dropped him on the floor
next to the saucer, "you've already gotten your treat today, you'll just have
to wait" scolding the boy sternly. The kitten stared at his master, batting his
lashes while his pupils dilated, ears laying flat against his small head, "but
don't you want to play with me, master?" Ciel spoke around the thumb now
hanging out of his mouth, moving his tongue around it, seeing the hard line of
Sebastian's cock through his black dress pants. Grabbing the bridge of his
nose, Sebastian turned away and headed towards the desk. Not two minutes later
he found himself with a lap full of Ciel; the kit writhed on his master's
obvious hard on, big mismatch eyes staring innocently up at Sebastian, the
vibrations of his purring only adding to the sexual frustration. Sebastian
absentmindedly stroked the small kitten's tummy while trying to hide the
massive erection from his needy kitten, but Ciel was already all too aware of
his own victory. The kit rolled around Sebastian's lap, 'accidentally' nosing
his hardening nipples while nuzzling and kneading his abdomen in content, his
own erection leaking all over the older man's vest while his nimble tail worked
over his master's cock. Sebastian smoothed the hair on top of his kitten's blue
head, pushing the downy hair back with his matching ears, working down the nape
of his neck and back, the kit responding by arching into his master, mewling as
his own sensitive and hard nipples brushed the coarse fabric, "you're being
very naughty kitten, trying to distract Master while he works", Sebastian
whispered into Ciel's kit ears, hot breath eliciting more beautiful sounds from
the small form on his lap and kissing the top his small head, still entranced
by the sensations. Ciel shuddered thinking he had already won, but was quickly
disheartened as he found himself once again in his master's arms being plonked
next to his bowl and saucer, "now, behave kitten". The kitten pouted as his
stubborn master went back to work, tail indignantly sweeping behind him, one
way or another Ciel would get his master's attention.
    The kit padded up to the desk, stopping next to it before yawning loudly
and stretching forward, lithe body extended as he displayed his exquisite ass
and deft limbs. When returning back to a more 'casual' sitting position, Ciel
began grooming his small hands, coyly watching Sebastian out of the corner of
his purple eye; his master player the dutiful role of focused accountant, but
his hard on betrayed him. The kit continued licking himself clean knowing his
master was mentally imagining far better places to clean with that sinful
little mouth. Once Sebastian quickly glanced at the kitten, eyes displaying his
true desires, Ciel moved next to the older man, beginning by nosing his clothed
calf, purring gently and delicate tail playfully swaying. Sebastian's breath
hitched when his kitten began to rub against his leg, though admitting it would
imply that Sebastian knew there was something mischievous about the act and
that he was in fact watching the kit throughout his entire performance. 
    Once Ciel was satisfied with his progress, the kitten moved onto his
master's thigh, skittishly pressing his small face into the lean muscle; Ciel
could smell Sebastian's desire and smiled deviously as he began to kiss his
master's leg, beginning at the knee. Sebastian stared down at the small kitten
once he began using his mouth on him, "Ciel, what did I say?" Sebastian spoke
breathily but sternly, chest rising slightly; the kit looked up through his
long lashes, ears tipped down looking like the picture of erotic innocence.
"But master, I'm still hungry", distracting him enough to get the loose button
of his master's pants undone with his agile small fingers, "why didn't you say
so ear-", Sebastian's words were swallowed along with his throbbing cock, a
wicked smile surrounding his sensitive head. Ciel gave his master's prick one
good swallow before kissing and licking down the sides, "nothing fills me up
the way you do, master"; how his dirty little kitten could say such perverse
things with such innocence was far beyond Sebastian. The older man sighed as
the boy continued to twist his tongue around the head and nearly sucked a
bruise on the thick vein, continuing to his balls, almost playfully moving the
flat of his tongue around one then the other, running the tip of his little
tongue between them and then returning to his master's cock. Sebastian was
almost, almost, taken so close to orgasm to let it continue, however right
before Ciel could get his smutty way, Sebastian pulled the kit off his dick,
"bad kitten, Master is working right now. Go play with your toys", the older
man spoke with an edge of malice though his breathing was still uneven and his
cock was still  swollen and throbbing. "I am, Master, you're my favourite toy",
the kitten looked up with the face of an angel painted with the intentions of a
devil. 
    Sebastian stared for a moment, hellishly turned on both by this filthy
kitten and the desire to remind him who was whom's toy. "Is that so, kitten?",
Sebastian's tone was tainted with the latter. The man picked up the young kit
and sat him straddled on his lap, grabbing the small erection and running his
own thick length between the boy's legs, "do you believe me to be your toy?
Your plaything to use when you please?" Ciel mewled loudly, leaning onto his
master and digging his face into the crook of his neck, hot puffs of breath
decorating Sebastian's neck while he stroked his kitten's hard prick. "You have
it very wrong, my naughty kitten, you see, I am your master, and I am one hell
of a master. Let me remind you who is whom's," Sebastian reached into the desk
drawer to grab (one of the many) lube containers and poured some of the cool
gel onto his fingers; Ciel looked over his shoulder and watched Sebastian pour
the liquid, but not soon enough to prepare himself for the unceremonious
insertion. Sebastian pushed two fingers into the kit, his entire body thrumming
with excitement, "this is mine. I will have it whenever I please, how ever I
please, is that understood?" A lilt of unfiltered moans discordant ahhs filled
the room while Sebastian continued to roughly open the kitten in a frenzy of
vexation and sexual frustration, his own cock sorely hard. 
    Once the kit was open enough, Sebastian wasted no time picked the small
form up and forcefully setting him on the desk atop all his neglected work.
Ciel instinctively opened his legs wide and leaned back onto his elbows as his
master slicked up his prick before viciously pushing in, beginning with a harsh
pace. Ciel shook from the force of Sebastian's pace along with the desk against
the wall, filling the room with near screams of pleasure as his master took
what was his. Sebastian leaned forward without missing a beat to suck the kit's
hard nipples while looking for the special bundle of nerves. The kitten looked
down to see his devilish master taking a pink nub into his mouth just as he
found the kit's prostate, leaving him an overstimulated wreck, "mas-master-" he
began to shout before painting the front of Sebastian's vest white. 
    The older man grinned fiendishly and watched the small kitten wreck under
his, hair and fur a mess and tail shaking uncontrollably; Sebastian didn't last
much longer as Ciel's body clenched around him, he groaned loudly as he coated
the inside of the kit. Not wasting much time, Sebastian picked up the kitten
and sat back down in the chair after gently pulling out of the small body, both
still a mess and covered in many fluids. Ciel purred quietly, very well spent
and content on his master's lap while he stroked his soft skin, dropping
delicate kissing over the kit as he went. It wasn't long before the kitten had
fallen asleep like that, spent, covered in his own come and in the lap of his
master, as happy as could be; Sebastian sighed, watching the kit sleeping
soundly on his lap, not looking forward to having to get back to work,
especially with his small naked form on his lap, still messy and partially
unclothed, but made no attempt to try and change that fate, instead smiled to
himself and sighed, "my my, what a needy kitten".
