****** Just a Tip ******
by LittleMistress
Summary
     Have you ever wondered how Ciel got such a wonderfully plump ass?
     Squats, or some form of them anyway.
Notes
     If I was told 4 years ago that if I watched kuro would be awake at 3
     am with my inner elbow stinging in pain from test smacks for the sake
     of accurate porn I would have laughed. Yet here I am.
     Dedicated to the Smut and Popcorn duo Silverwing26 and
     soulless_lover, the reasons I'm damned to hell.
***** Chapter 1 *****
The soft sound of knuckles rapping against the Professor's door was not
uncommon at Weston College, the Professor was known to be kind and some
students might even call him attractive, not that they would ever utter such a
thing aloud. However the student that stood outside the office waiting, the
boy, if he could really be called one, was not your ordinary child. No, but of
course neither was the good Professor Michaelis, the father who sat in the
office at his desk, could hardly be called a man.
"Come in." Sebastian stated just loudly enough for the student on the other
side of the door to hear him, putting corrections onto a student’s latin test
as his charge walked into the room. "Ah Phantomhive to what do I owe your
visit? Are you in need of tutoring?" the demonic Father asked as the student
began to close the door.
 "Why, yes Father I am in need of assistance with some... work." The student
announced just a bit too loudly before shutting the door as if he wanted to
make it known to all the other students in the hall, or rather the entire
school, that the Vicar would be unavailable for a period of time. However Ciel
did not drop the act of a regular student and instead played a role in a new
game he made as he went along.
Sebastian could tell what his master was was doing, and with a moment of
thought, knew what the boy was after. Work could be done at another time the
demon thought before setting his pen down and closing his ink well.
"You're doing well in Latin however, you could recite the Lord’s Prayer with
little difficulty, due to your Absolution in the Confessional." The demon said
with a low chuckle. The boy flushed scarlet before resuming his role in his
game.
"Ah Father, you have ways to...  pound  things into one's memory, which is why
I'll need your guidance today." the boy sucked in a quick breath as if he was
embarrassed before speaking
again."In physical activities I am... lacking. My marks are falling and soon
enough I'll be assigned Y's for them. Oh please good father can you give me
a...  tip ?"
The student’s face was plastered with mock worry but his words, the words that
left the boy's sweet lips held a double meaning to them that no good student
would ever dare insinuate, and the false Vicar could hardly hide the devilish
grin that briefly flashed across his features before smiling kindly.
"Ah my dear pupil why did you not ask sooner? I would’ve been happy to assist
you." The Professor's voice lowered to a delicious sinful tone before
continuing. "I will give you more than just a tip my dear child. But be warned
these sessions will be far more strenuous than our last few.
"Oh thank you Professor, I'll will try my hardest!" Phantomhive spoke with the
smile only a cherub could ever manage, and the eyes of an imp the student truly
was.
"I'm sure you will Phantomhive, I'll be sure to do so as well and test your
very  limits ." The mock Father spoke with a voice just dripping with lust. Oh
how he would ravage the “innocent” child before him but not without a proper
stretching.
Ciel’s breath caught in his throat at what sebastian had hinted at, before
swallowing down what shame he had as he watched the “Good Father” rise from his
chair and approach him with an inhuman silence, lust sparkling within those
ruby eyes. In those eyes however they also glowed with something else Ciel
couldn’t quite put his finger on, in that moment. It was uncomfortably familiar
and somewhat threatening but sent delightful shivers down the boy’s spine.
Without thought Ciel approached Sebastian while lost in those eyes, not taking
notice until his hands touched the wool of the cassock the demon wore. The
cassock the demon wore to keep the facade of the vicar he wasn’t, but Ciel
wouldn’t have it any other way.
“It seems you don’t have your physical education uniform Phantomhive, we’ll
have to make due in this.” The Professor spoke referring to the usual, stuffy
uniform worn by the student before him. “I suppose we could remove your coat
and waistcoat, though you should not be seen in your shirt sleeves outside this
room. It’s unfitting of an a student at this school, but in this case this
should allow for more movement.” Sebastian spoke with a grin as he began
unbuttoning.
Ciel became more at ease as he was rid of the tie and stuffy wool he wore,
leaving him in his thin, cotton button up shirt and uniform trousers.
“Shouldn’t you remove that as well Father?” Ciel spoke as he pointed to the
cassock and robes the demon wore. “Surely it would get in the way during our
session, right?” The student questioned, with a childlike tilt of his head as
the Professor set down his pupil’s folded uniform upon his desk.
The demon chuckled, “It surely would I would think, give me a moment to remove
my robes and cassock child.” Sebastian spoke as he too stripped down to his
white button up shirt and dark trousers, folding his own uniform and placing it
next to his master’s, before once again fully facing Ciel before smirking.
The child had been ogling his demon as he had undressed, mouth agape and nearly
watering as he remembered each detail of his demon’s body the cloth hid from
his eyes. When Ciel had come to his senses Sebastian stood smirking at him, he
had taken notice of what Ciel had been doing but all shame had been thrown out
the window moments ago.
With that the student returned to his role in his little game, “Then shall we
begin Professor? I’m ever so eager to learn.” cherubic smile returning to it’s
place upon the boy’s lips in sweet irony.
“Why yes Phantomhive, sit as you would while beginning your morning stretches.”
The false Vicar said with a smile that only spelled trouble for a certain
student. “I shall teach you some new stretches that should help you become more
limber.” the Professor continued.
“Oh hell this bloody demon is going to actually put me through a physical
education lesson.”   Ciel thought to himself before doing as he was told and
sitting cross legged on the floor of Sebastian’s office, no need to complain
and sit on a sore behind later. The aforementioned demon stood tall in front of
him, before kneeling to his own level and leaning forward to adjust Ciel as
needed.
“Let’s test the flexibility of your legs, my child.” Sebastian spoke softly
almost in a hushed tone, and as Ciel’s legs were spread and adjusted did he
realize the close proximity he was in with Sebastian. How intimate the
situation was, how close he could just do what many students at Weston desired
and kiss the demon before very his eye. However as with most things, involving
Sebastian Michaelis, Ciel Phantomhive didn’t get to such a thing with ease, due
to a horrid, new, and unfamiliar pain in his inner thigh near his pelvis.
“And this is called the butterfly position, do hold your feet as close to your
groin as possible Phantomhive.” Sebastian said in a warm tone tinted with
mirth, his young master was always the lazy lover, what better way to train him
for future sexual escapades.
“A-ah Sebas-” before Ciel could fully voice his pain and complaint he was
silenced by a gloved finger to his lips.
“Ah ah ah Phantomhive, you shall refer to me as Father or Professor Michaelis
while here, we wouldn’t want any unnecessary punishment now hm?” The bastard of
a demon was clearly enjoying seeing his master muster through the pain and keep
himself in this butterfly position.
“F-father please this is r-rather painful.” Ciel spoke with sickly sweet venom
lacing every word. “I-I’d like to st-stop.” He said with a slight strain
evident in his voice.
“Oh come now Phantomhive we’ve barely started, begin leaning forward to
complete this exercise quicker.” The Professor spoke with an amused smile as he
gently guided his pupil forward only worsening the pain Ciel felt.
“If that’s how he wants to play it I’ll have to return the favor.” Ciel thought
before making a choice he would soon regret. “”Aaahhh a-ahaa P-professor
Professor it hurts!” Ciel moaned loudly in pain as he was pushed forward and
held at a near 45 degree angle with the floor, panting and moaning obscenely
just as he usually did when being thoroughly fucked.
Slowly the Good Professor’s smile became tightlipped as he listened to the
melodramatic yet alluring moaning and groaning of his pupil, just as the front
of Sebastian’s trousers became tight at the little performance Ciel gave. Ciel
knew how to get the reaction he wanted but, didn’t expect Sebastian’s next move
until he was pushed forward near parallel with the floor for a brief moment
before Sebastian let up, sending Ciel backwards onto the floor with a small
“Oof!” as the previous resistance of his butler’s hand was now gone.
“Sebastian! What in the blue hell do you think you’re doing!?” Ciel huffed
angrily, not taking notice of the hard ridge in his demon’s trousers, as he sat
up and rubbed the back of his head and inner thighs. The last moment Ciel had
been parallel to the floor was very brief but worsened the soreness that was
present near his groin.
“Phantomhive.” That voice and tone sent a crawling feeling up the student’s
spine, and left him very confused about how he felt about it, despite knowing
the trouble it meant for him. “Did I or did I not tell you to refer to me as
Professor or Father?” The demon never broke character in his master’s games, it
was against his aesthetics and often, to Ciel’s horror and arousal, became too
in tune with his authoritarian side.
“Y-yes Professor Michaelis.” The boy spoke timidly as he reprised his own role.
“Yes what Phantomhive?” The false vicar spoke in a strict tone that could send
shivers down the spine of anyone who heard it.
“Yes you did Professor Michaelis, you told me to refer to you as such.” The
student spoke with false remorse as he became more and more aroused of what was
to come, all while still seated on the floor.
“Stand. You shall have to be punished my dear child, come lean forward on the
desk.” The demonic Vicar spoke as he began removing his gloves and dropping
them to the floor.
Ciel did as he was told and leaned forward against the desk, rump pushed out,
already aroused and ready for what was to come when he felt a warm hand caress
his ass. The child bit his lip as the hand traced forward to the crotch of his
trousers, undoing them with ease and allowing them to drop to the floor,
drawers following moments later. Ciel’s cock was now in the cool air of the
office but he felt no shame nor pride about it, just need as it was neglected
in favor of his ass and punishment.
Sebastian admired the pale soon to be rosy skin of his master’s plump little
rump as he ran his hand over it once more before speaking smoothly. “Five
smacks should be a suitable punishment for mouthing off. Do count them
Phantomhive or I’ll be forced to have to start over.”
“Yes Father Michaelis.” Ciel spoke evenly before he heard air being displaced
and felt the sting Sebastian’s palm on his rump almost immediately after. “Ah!
O-one Father.”  Ciel spoke with slight strain, he knew this would be the end of
him.

Chapter Notes
     I just finished this and couldn't wait to post it hope you all enjoy
     this!
See the end of the chapter for more notes
Four smacks followed the first by the hand of the good Professor, each counted
off by his pupil and each horribly accurate in their placement and pleasurable
sting. And now an inhumanly cool hand stroked along the reddened rear and sore
inner thighs of a quivering Ciel Phantomhive, who still stood leaning forward
against the desk, fully aroused and dripping.
“P-professor p-please… touch me.” The student almost begged, just almost.
“But I am Phantomhive. Please be more specific.” The demon was painfully hard
in his trousers, but what not make any sudden moves unless told outright. But
oh how he thirsted for his master, and his intoxicating aroma just made it all
the more difficult to keep from rutting against the boy then and there.
“H-here Professor…” Ciel said shakily as he led one of his demon’s hands to his
cock, “a-and here, t-touch me here.”  Ciel spoke as he led Sebastian’s other
hand to his tight opening. The boy was ready to fall apart and needed his demon
to finish it.
“As you wish my wicked child.” Sebastian said before retrieving a vial of oil
from seemingly nowhere and pouring a generous amount over his fingers and going
to work on easing the first finger inside his master while simultaneously
stroking his cock to distract and relax the boy further. With little trouble
the first finger went inside, Ciel shuddering in response as Sebastian crooked
his finger looking for the boy’s sweet spot.
“Aaahhh Sebas.. P-professor Michaelis… aahhhn…” Sebastian chuckled low as he
crooked a finger slowly, teasing his master as he whimpered and writhed beneath
him, making the demon crave his boy even more than he already did. And as
Sebastian added a second finger he stopped stroking his master in favor of
leading one of Ciel’s hands to his own hardened arousal.
Already knowing what to do Ciel began stroking his butler through the cloth of
the demon’s trousers before somehow managing to tug them open, buttons be
damned. He reached in for his prize, carefully pulling Sebastian’s cock out and
stroke him in the open air without much effort, he was good at what he did, too
good for an “innocent” student, not that Ciel cared much. He was damned the
moment Sebastian came into his life, what use did he have for innocence when
sinful pleasure was far more appealing.
Sebastian set to stretching his master further as he was stroked by a small,
delicate, talented hand, it was almost too much to bear. Ciel’s arousal was
evident in his scent and the demon could tell the boy would not last too much
longer, and it drove Sebastian absolutely wild though he would not dare break
his role in this game.
Ciel moaned loudly as a third finger was pushed inside his body, oh how close
it brought him to the edge, how much he wished to stay teetering in such
torturous pleasure forever, as  his  demon thrust 3 fingers in and out slowly
he went back to stroking Ciel once more trying to push him off that edge and
have the boy crumble in his arms.
“Professor… please I’m going to… aaaahhhh!” The student cried as he came in the
false Vicar’s hand, the boy’s hand stopping his ministrations to his demon’s
cock in favor of clawing at the desk he was against, all while clenching around
the three fingers buried in him. And as Ciel continued to convulse on the desk,
relief and lust lacing his sweet whimpers, Sebastian brought his hand up to his
own mouth and licked the sweet droplets of Ciel’s cum. Without a word the
Professor removed his fingers from the child and caught his wicked little
student before the poor boy crumpled to the floor in post orgasmic bliss.
“Phantomhive, I do think we should continue with your lesson, hm?” The Father
spoke before seating himself on his desk and having his student straddle his
lap, stroking their cocks together with his contracted hand. The student
squirmed and whined as he felt blissfully overly stimulated, quickly becoming
hard again as his eyepatch was carefully slipped off and discarded by the other
hand of the supposed Father. It revealed his own sign of his unholy contract
with the devil currently going to work on him, exciting the demon immensely.
“What should I do F-father?” Ciel spoke trying to keep his voice steady though
it threatened to waver as the boy felt breathless. Trying to concentrate at the
task at hand if he wanted even more of only what his devil could provide, what
he could coax out of Ciel.
Sebastian stopped stroking himself and his master before he pushed his work
back to the very edge of his desk and laid back. “You need to strengthen your
legs Phantomhive, why don’t you put them to use while riding me?” Sebastian
spoke with the warmth yet commanding tone only Professor Michaelis would
provide, yet no good Professor would ever dare say that to a student.
At those words the student flushed scarlet and assessed his options, no need to
end up with an even sorer rump, and it seemed the vexing Vicar smirking up at
him had no intention of making a compromise. Perhaps he should’ve asked for
tutoring in latin instead.
“Well, my dear pupil, what are you waiting for?” The Professor questioned as he
waited for his student’s next move in his game. He watched the boy above him
swallow back his pride and trade it for a look of determination, and a small
smirk.
“Nothing Father Michaelis, I was merely lost in thought.” Ciel had quickly
regained his composure, before grabbing his demon’s cock and lining it up with
his well stretched opening. This took Sebastian by surprise and he could only
watch as his master lowered himself onto his arousal with little strain in his
face.
“Oh Professor… you feel so good.” Ciel spoke with a delicious moan, face
flushed and full of confidence as he began riding his demon slowly, feeling him
twitch within his body. “Is this what you wanted of me Professor Michaelis?”
Ciel said with slight breathlessness as he sped up, putting a real strain on
his thighs for the sake of making his demon crave him more than he already did.
And Ciel could tell how close his demon was to losing his composure by simply
looking into those inhuman red eyes.
“Ohhh god right there Father please.” Ciel moaned out loudly as Sebastian
thrust once right into his prostate, causing the demon to chuckle and do as he
was so kindly asked. The Good Professor continued to meet his students hips
with a thrust to the boy’s prostate, causing the pupil to close his eyes, and
lean back on his arms as he moaned and cried aloud in the office not caring all
that much if someone outside the door could hear if they paid enough attention.
However Sebastian being a bit more clear in the head, although not by much,
knew how detrimental it would be for someone walking along to hear his master’s
moans. Though it pained him slightly to silence Ciel’s sweet cries of pleasure,
Sebastian sat up once more and pulled the boy in for a searing kiss to muffle
his moans.
Ciel without thought accepted the kiss, wrapping his arms around Sebastian’s
neck, turning a deep kiss into a bruising one as he parted his lips, inviting
his demon’s tongue to tangle with his own. The boy only moaned louder as
Sebastian took the invitation and thrusted harder to meet his masters still
moving hips as they kissed messily. Drool left the boy’s reddened lips as they
parted for a brief second to breath before kissing desperately, as if it would
be their last.
Sebastian’s hands helped guide Ciel’s hips as the boy’s legs began to falter
from sheer exhaustion and crippling pleasure as his sweet spot was repeatedly
hit with brutal accuracy. Ciel’s hands slipped into inky black locks and tugged
helplessly as he felt the end draw near though it was far too soon for a
certain Vicar’s liking, he needed to take action and decided to break their
kiss as the boy panted and whined  
“You can keep moving on your own right Phantomhive? We aren’t even close to
finishing your lesson.” The false Father spoke before removing his hands from
Ciel’s hips in favor of wrapping one around the base of his young student’s
little cock, halting his approaching orgasm.
“Aaaahhhh P-professor! What are you doing I-I need to… aaahhhh!” Ciel cried and
whimpered as pain and pleasure flooded through his body from not being able to
cum again, stopping the movement of his hips. “What did you do? W-why can’t I-”
The boy asked before he was interrupted by a quick kiss.
“That would’ve ended your lesson too soon Phantomhive, you still need to work
those legs of yours if you want better marks in physical education.” The good
Professor said as he continued to thrust up into his overstimulated pupil. “You
wouldn’t want to be assigned any Y’s would you?”
“Hnn.. ah no Professor, t-thank you Professor.” The student whimpered out as he
began to move his hips up and down in rhythm with his Professor deep thrusts.
The boy closed his eyes while biting his bottom lip as if to not let any more
shameful sounds out, they would most definitely be louder and more desperate
than before.
Sebastian smirked as he watched the boy bite his lip and screw his eyes shut
before arching his back and throwing his head back a bit, exposing his throat,
Ciel made it far too easy for his demon to tease him. Sebastian immediately set
on sucking on the skin of his little master’s neck causing Ciel to moan as
quietly as he possibly could as he allowed Sebastian to do what he pleased to
his body. He would allow the demon to do whatever he wanted if it meant Ciel’s
pleasure would be put first, though he never would say so, the amount of
trouble Sebastian could get him into would be devastating once he came down
from the high of an orgasm. Then again it was against the demon’s butler
aesthetics to cause any harm to his master’s noble name, he doubted any trouble
would be long lived.
“Hnnn… Father Michaelis… i-it feels so good it’s so g-good. Please more, m-
more!” The boy begged sweetly as he pulled back and looked into the false
Vicar’s eyes pleadingly. Sebastian knew he nor himself could last much longer,
as the boy grabbed onto his shirt and pressed desperate lips against his own.
Ciel moved his hips faster in hopes of coaxing the same reaction from
Sebastian’s letting out a satisfied moan against Sebastian’s lips when the
demon thrust harder and faster against his prostate. The boy gripped the false
Vicar’s clean dress shirt so tightly he could feel his own nails digging into
his palms painfully, not caring though as his pleasure was much more important.
Ciel felt as if he could not let up for a moment lest his demon would too, only
causing his building orgasm to be delayed even longer.
However on Sebastian’s end he knew he could not draw out this game much longer,
he was at his very own limits, his master was at his wit’s end. He had
fulfilled his role in his master’s game, made good on his promise and now he
knew it was time to end it all, taking Ciel over the very peak of pleasure with
him. He pulled away from the boy’s kiss and leaned in to whisper sweet nothings
to Ciel as he stroked the boy’s cock.
“My child, you’re doing so well. I do believe it is time to draw this lesson to
a close don’t you?” The Professor asked while panting lightly, trying not to
groan into his pupil’s ear. The student practically grinding his hips onto his
Professor’s cock, felt pleasurable shivers go down his spine as he was stroked
and spoken to at the same time. He tried his best not to cry out as he
answered.
“Ah y-yes Father Michaelis… I-I want to.. I w-want to cum… P-please kind F-
father let me… aaahh..!” The good little student whined out as he felt his
orgasm fast approaching, burying his face into the false Vicar’s neck and
taking in his intoxicating scent. “P-please… let me c-cum.” The boy whimpered
desperately.
“Very good Phantomhive, asking so nicely.” Sebastian spoke before stroking Ciel
faster and fucking Ciel faster than his master’s legs could keep up with. “I do
think I’ll let you cum now. Call for me, say my name young master. The name you
gave me.” Sebastian asked with a honeyed tone as he felt his master clench
around him.
“Aaaahhh Sebastian! Sebastian Sebastian oh god aaaahh…!” Ciel cried loudly as
he spurted on his and Sebastian’s dress shirts. Orgasm hit him brutally, his
body practically turning into jelly as he convulsed oh so lightly, allowing
Sebastian to use him until he too came.
It didn’t take more than a few more powerful thrusts into the now lax body of
his master for Sebastian to hit his own brutal orgasm, and came violently
inside Ciel, groaning as he did so as if a huge weight was lifted off him. It
took a few moments but once Sebastian regained his composure he lifted his
little master from his now softening cock and into his lap as Ciel caught his
breath.
“I believe you have the stamina and strength to get better marks in Physical
Education Phantomhive. Though we should do this a few more times to properly
train your body.” Sebastian said in an amused tone before he heard and almost
childlike giggle come from Ciel.
“Of course Professor Michaelis. Would you be so kind to help me clean up? Latin
is next yes?” Ciel said with a breathless smile before pecking the lips of his
demon.
“Oh my it seems so. Let’s hurry and clean up.” Sebastian replied before pecking
his master’s lips. “We wouldn’t want to be late.”
