Summary
     Pure smut. Just smut. Nothing but smut.
   Small thighs hit the bed as Ciel backed up slowly, enraptured by the
powerful eyes burrowing into his own. His hands were gripping the lapels of his
servants black waistcoat as he was pushed onto the bed gently, but with a
certain ferocity he had become familiar with.
      Sebastian wasted no time in lifting those slender legs into the air,
removing the articles of clothing covering them. First came the heeled shoes,
followed by the socks and the garter hooks. A chaste kiss was placed on the
smooth ankle, Sebastian's crimson eyes never leaving the mesmerized blue of his
lover. It seemed like only seconds to Ciel before suddenly his clothes littered
the floor and he lay naked and vulnerable, but he felt no insecurities. These
were the eyes that saw into his soul. And the hands that were now removing that
heavy tailcoat, those were the hands that rescued him from damnation.
    His equally naked lover joined him on the bed, banishing all such thoughts
from his mind. Sebastian reached out and danced his fingers teasingly along the
expanse of Ciel's milky white thighs, noting the change in breathing that
occurred as a result. "Does this feel pleasant to you, young master?" Sebastian
murmured pleasantly with all the aesthetics a proper butler should have as he
leaned forward to press kisses to the inside of Ciel's knee. Ciel did not
justify that question with an answer, even though the subtle pink dusting his
cheeks served as answer enough. Slender fingers trailed their way up past
curved knee caps and lightly developed thigh muscles, stopping at sharp
hipbones and kneading them gently. "And this, my lord? How does this feel?"A
sharp gasp followed by a reprimand were quickly issued, "Are you going to
continue treating me like some china doll? I am not delicate, and stop speaking
in that damned-" Ciel's irate tirade was quickly cut off by a hand grasping his
chin and directing it up to meet Sebastian's lips.
     The sudden kiss continued on intensely until the boy broke away, panting
for breath. Sebastian gave a pleasant smile before speaking. "Is that how the
young master wishes to be treated tonight? He need only say the word, and his
loyal servant will behave as such." Ciel stubbornly clamped his mouth shut and
immediately refused to speak his desires, pride once more becoming an issue.
Sebastian cocked his head to the side and let his hand drift down to grasp the
half-hard cock between Ciel's legs. Multi-colored eyes widened in surprise and
a small fist was stuffed into his mouth to stifle a gasp. Black-tipped fingers
lazily stroked up and down in a light grip, fingers barely touching as
Sebastian grazed a kiss along Ciel's collar bone. "Does the young master enjoy
this?" He asked in a low voice, delighting in the small squeak Ciel emitted
when he tightened his grip slightly.
     Coltish legs spread further, inviting the devil closer, and he certainly
took advantage of that. A borderline wanton moan erupted from Ciel as
Sebastian's hand tightened into a fist, other hand trailing over the soft
globes of his ass. Ciel squeezed his eyes shut and bit his lip in a fruitless
effort to stay quiet as a single finger slipped down the crevice of his
backside, massaging slowly. "And is this to the lord's satisfaction as well?"
Foolish pride inhibited Ciel from crying out, from begging for more, and it was
an unfortunate fact that Sebastian was fully aware of this. He continued to
torment his master's body, increasing the pressure in his fist slightly.
    Sebastian removed the finger from Ciel's backside and lifted it to his
mouth, sucking it liberally before bringing it back down and firmly rubbing the
puckered ring of flesh residing there. And Ciel /moaned/, immediately clamping
his mouth shut once more even though he pushed back against Sebastian's finger.
Sebastian pretended to perk up at this. "Did Master like that? It is such a
pity I have no way of finding out, such a stubborn Master I serve. Ah, well."
The butler reluctantly started to pull his finger away when a desperate cry
from Ciel halted him. "Please! D-do not withdraw. I-" Perhaps the deadliest of
the seven deadly sins inhibited him once more, the blush on Ciel's face
comparable to a rose as he struggled with his desires. To admit them was to
admit defeat. However to not admit them and be left high and dry? Ciel was
unwilling to accept that as well. Sebastian made the decision for him when he
leaned forward and engulfed nearly all of Ciel's cock in his mouth at once. A
loud groan echoed around the room as Ciel teetered on the edge, just about to
give in. As the moments passed, the suction around his cock got more and more
intense, leaving Ciel panting with tears forming in his eyes.
     With a small smirk, Sebastian pulled away and leaned in towards his
master. "I can give you all of this and more, my lord. Just say the words and
you shall have it. Anything you wish of me." Ciel moaned at the words before
stuttering out a desperate wish, "Yes! Yes, I-i like it! Please, please more,
Sebastian! I want you to f-fuck me! Please!" Sebastian let out a breath at the
words and grinned, exposing teeth that surely were not human before crooning
his favorite phrase, "Yes, my lord." Two saliva-covered fingers slipped inside
the bluenette, who was still panting from the intensity of the pleasure he was
experiencing. Sebastian wasted no time in scissoring his fingers deep within
the boy, stretching him liberally. Of course no amount of stretching could /
truly/ prepare such a small body for copulating with him, Sebastian reasoned as
he withdrew his fingers once more.
     Sensually licking his hand, he made sure Ciel was watching as he slicked
up his own cock, rubbing with a firm grip and letting out a small groan as he
did so. Ciel bit his lip from the sight and begged once more, "Please,
Sebastian I cannot wait any longer, I need you to fuck me now, just ple-Ahhhh!"
Sebastian was fully seated within his master before he even finished speaking.
Ciel's words had devolved into small, broken moans as he tried to adjust to the
alien feeling of being filled. It was mere moments before Sebastian started to
move, knowing exactly what his little master could handle and where the limits
were.
     Short and shallow thrusts were given and Ciel's breathing remained largely
unchanged, even slowing down a bit as he relaxed. Sebastian kept the slow pace,
pumping himself in and out of his master at a tortuous pace, knowing it would
ultimately end up with his master begging once more. And he did truly love to
hear his master beg. Surely enough, it only took a few more moments before Ciel
was pleading once more. "Faster, please! H-harder! You're a demon, aren't you?
Prove it. F-fuck me like the demon you-" His impertinent words were cut off
with Sebastian capturing his lips with his own before beginning to truly move.
Strong arms braced themselves on either side of Ciel's head as Sebastian drove
his hips forward ruthlessly, finally indulging in the pleasure he had been
seeking out.
     A stream of nearly constant moans was flowing out of Ciel's mouth, who was
for all the world trying to participate by rocking his hips back to meet
Sebastian's thrusts. Every sound that left the bluenette's mouth made Sebastian
want to claim him more, until he was fucking Ciel at a near feverish pace.
Unsurprisingly it was Ciel that spent first, arching his back and squeezing his
eyes shut in a silent moan as he spilled all over hi stomach. Sebastian grunted
in resignation at the situation and pulled out of the boy, chest heaving from
physical activity and seemingly being denied his release. Luckily for him, Ciel
was not a selfish lover.
     As soon as he came down from his orgasm, Ciel gestured almost shyly at
Sebastian and lewdly motioned for him to fuck his mouth. A breathless chuckle
tinted with relief left Sebastian's mouth as he shifted positions on the bed so
that his cock was touching Ciel's lips. "How crass of you, my lord. It would be
my pleasure." He purred, thrusting into Ciel's mouth. Ciel hollowed his cheeks
and gripped Sebastian's thighs and stared up at his butler, wanting to get him
to release as quickly as possible. It did not take long. A clever flick of the
tongue here, a small moan there, and an especially hard thrust into the tight
throat was all it took before Sebastian released into Ciel's throat. He watched
as some excess seed spilled down the sides of the noble's mouth and wiped it
away, licking his fingers clean. "Hm. It is not nearly as pleasant tasting as
yours, my lord." Sebastian sighed in a put upon manner as he grinned at the
flush that appeared once more on Ciel's tired face.
     "Shut your mouth, you bastard. Hold me, now." Ciel mumbled with a small
yawn. Sebastian imperceptibly raised an eyebrow. "Is that an order?" One cross
glare was all it took for Sebastian to chuckle and slide into bed besides Ciel,
collecting him in his arms and holding him close. "Do sleep well, my lord. You
have an extremely full schedule tomorrow." A disgruntled murmur of assent was
all that was heard before Ciel slipped off to sleep. Another chuckle and
Sebastian kissed the top of his contractor's head. "Goodnight, Ciel."
