****** That Butler, Humiliated ******
by TheVillainousNoble
Summary
     Before, Sebastian thought that vengeance was petty. However, after
     being degraded, he made Ciel's goal his own.
Sebastian’s emotional state was now beyond irritation. His anger was now slowly
                   but steadily approaching a boiling point.
 It started out with Ciel finally getting a solid lead on the people who were
   behind the events of that one month. Those petty noblemen who sacrificed
children to sate their own greed? They were nothing. Not even pawns. They were
  just nothing. It turns out the whole things was so much bigger than someone
                             worshiping the devil.
 So Ciel and Sebastian headed out to explore the lead, even put all of Ciel’s
resources into the investigation. It seemed like it was all for naught because
  the search gave no results, but then they were captured, and now they were
 here, where ever here may be. Sebastian was shackled up with a sack over his
 head. You may find it funny that something like this would restrain a demon,
but whoever it was that imprisoned the devil, knew what they were doing because
        Sebastian felt as weak as a human would in such a predicament.
 Sebastian didn’t know were Ciel was; he couldn’t sense anything. All he could
tell was that there were moving figures in front of him from time to time. When
  someone came up and crouched before him, he clenched his hands into fists.
 Nothing good was going to come from a situation where a human has full power
                                 over a demon.
A the light sound of a pocket knife’s blade being flipped open could be heard.
  Then Sebastian felt the sharp, cold tip against his abdomen. What are they
  going to do? If they can retrain me like this, then can they gut me too? Is
  this how I am going to die? Were the thoughts that ran through the demon’s
  head. For the first time, he was afraid of death, even if for a moment.The
 blade ran up Sebastian’s front through his vest and dress shirt, plucking the
   buttons off. Then the blade was removed and the bottom part of the ruined
 garments was torn open to fully reveal the man’s front. Are they going to try
 to mock and beat me? Sebastian though again. Again, his thoughts were proven
 wrong when something extremely thin and sharp pressed into his lower abdomen
   and then pierced into his flesh. Sebastian tensed up, teeth clenching and
baring under the sack on his head. He felt the fain feeling of something being
  injected and instantly knew that something worse would happen than what he
 thought. It was on rare occasions like these that the demon was proven wrong
                                 about humans.
  Thirty minutes passed, but for Sebastian it felt like hours. He was feeling
 unbearably hot, tight in his own clothes, and somehow overly sensitive to the
 air in the room as it felt much colder. The sack on his head was lifted over
the bottom half of his face when he began to pant. His own body felt heavy and
his joints felt weak, something Sebastian only knew humans could experience but
now he was acquainted with the feeling as well. His mind was in a haze, but if
it weren’t, he’d recognize his symptoms as the effects of a strong aphrodisiac.
Of course, because he was a demon, this took him much longer than it would with
                                   a human.
“Is he ready?” Came the first voice Sebastian heard in hours. “The other one’s
                          already crying from need.”
   “Yes, he’s good to go.” Came another. The voices were male. The first one
         belonged to someone older and the second to someone younger.
   The other one? Who are they talking about? Could it be… Master? Sebastian
  managed to form the thoughts despite his hazy mind. Then rusty, metal doors
  opened. Someone came in and the sound of pitiful whimpering could be heard.
  Sebastian recognized the voice as his master’s and felt his erection throb.
 Then two men came up to Sebastian and hauled him up to his feet. They pushed
him to walk forward. Where, Sebastian didn’t know. But then he was pushed down
  to rest his front against a table. The men tore off his pants, leaving the
 butler in quite an unpresentable state. Sebastian shivered at the feeling of
                    cold air touching now more of his skin.
  They hauled him up onto the table and made him stand on his knees while his
 front was resting on the table. With his ass up in the air, Sebastian really
    didn’t expect anything else but torture to come to his genitalia. Then
 something else was placed onto the table behind him. Judging by the whimpers,
he understood that it was his master. When a hand with something wet and slimy
   rubbed up between his buttocks, Sebastian knew exactly what was going to
                                    happen.
 Ciel was urged forward until he bumped into another body. He didn’t know yet
  who it was, where he himself was, and what was going on. The effects of the
 aphrodisiac were much stronger on him. A pair of hands held his hips, another
hand took hold of his member. Ciel gasped at the sensation of the first contact
 he got in what felt like forever. Someone held Sebastian’s buttocks apart and
 the demon managed out a growl. But the sound of warning fell upon deaf ears.
   Everyone in the room aside from Sebastian and Ciel knew who was really in
                                    charge.
Ciel was pushed forward and then the head of his member was made to slip into a
   tight ring of flesh. Ciel gasped and his hips shook as the absolutely new
sensation drove him over the edge after half an hour of mad arousal without any
help to ease it. Sebastian bit his bottom lip as he felt something warm and wet
spill into him. How dare they do this? How dare they humiliate us this way!? I
won’t let them walk free! Were Sebastian’s thoughts of anger, but right now, he
couldn’t do anything, not with the drug in his system that even he couldn’t get
  rid of. Ciel was pushed forward until he slid all the way into the heat he
   didn’t know belonged to his butler. It felt so good he couldn’t think of
 anything but the pleasure. The hands of the men holding the two were gone and
  now it was just them. No doubt, the rotten humans were watching them. Ciel
 leaned over Sebastian’s back and panted. At first, his hips moved slowly. But
    once he got a taste of the friction and the tightness, he wanted more.
Sebastian clenched and gritted his teeth together hard. Ciel was now thrusting
into him like a young hound crazed by heat. Worse than the situation itself was
the fact that Sebastian felt good. He never knew something like this could feel
  good. Of course, being inside his master felt absolutely divine. But being
taken from behind by a child and actually feeling good? This situation was far
   more humiliating than Sebastian was preparing himself for. He blamed his
 sensations on the drug, but that still didn’t stop the sex from feeling good
                          and his body from reacting.
Suddenly, something was hit inside Sebastian and he gasped. Involuntarily, his
 walls tightened around the length and Ciel moaned. The sudden tightness made
the boy feel better and he thrusted harder, more desperate now. He kept hitting
  that spot and Sebastian couldn’t keep himself from making sounds he thought
he’d never make. He felt Ciel’s little balls slap against his perineum from the
force of the thrusts. His own nether swayed between his legs, his dick leaking
precum copiously. Ciel was good. Though it may be by complete accident, but he
 was good. With every thrust, he rammed into Sebastian’s prostate and soon the
             demon was pushing his hips back to meet his human’s.
The men watched the two drown in each other’s pleasure. When Ciel spent himself
  inside Sebastian again, he kept moving. They could have let the two be, but
they decided to further prove their control. Ciel was pulled off Sebastian and
the butler felt a pang of worry in his chest for what could be done to his boy.
   But then he was flipped over onto his back and his legs were spread. Like
before, Ciel was positioned over him and meant to enter. This time, Ciel pushed
 in all the way on his own. He spread his legs apart so he could move better,
            thrust harder into the heat that he fell in love with.
 “Master.” Sebastian let out in a heavy voice. He wrapped his legs around the
boy’s hips, crossing them behind him to hide the sight of penetration from the
 sick men’s view. He brought his arms over the small boy’s frame and held him
                        close. “Master.” He said again.
       Ciel stilled suddenly. “… Sebastian?” He asked in a small voice.
 “Yes, master.” Sebastian wanted to run a hand over the boy’s hair and cup his
          head but he found that Ciel too hard a sack over his head.
 “Sebastian, this… This…” Ciel started, it was dawning on him now what exactly
                   was happening and panic was coming fast.
“Shhh,” the demon soothed, “don’t worry.” He squeezed Ciel harder. “I’m sorry,
 master… But there is nothing I can do. I have failed as your butler.” Saying
these words made Sebastian aware of his anger once more. “But there is a way to
                bring it all to an end… So keep going, master.”
Ciel was silent and still for a bit before his hips started to move again. Slow
at first, they quickly picked up the fast pace and Ciel continued to pound into
  his butler’s body. Sebastian noted that the effects of the aphrodisiac were
  slowly wearing off. His mind was more clear now. All that was left was his
body. Ciel’s panting quickened and his thrusts grew more frantic. Soon, he was
  spilling himself into Sebastian again and finally the demon ejaculated too.
   The two laid panting. Sebastian finally felt his mind clear again and his
 strength was returning. Any moment now, and he’d be able to free himself and
 tear all these people to bits before tearing down the building and flattening
    it with the ground. But then came a strong hit, and afterwards was just
                                   darkness.
 When Sebastian came to, he was fully restored. At first, he scanned the place
for any signs of life with his senses and only found his master’s presence. The
 boy was still top him. He broke the shackles off his wrists and tore the sack
 off his head. The first sight before him was Ciel, well and alive, currently
 unconscious. Both of them were in a humiliating state so Sebastian first made
          himself presentable and then wrapped Ciel up in his jacket.
The discovery that the place was empty was not surprising, but that didn’t make
it any less angering. If before vengeance was just Ciel’s goal, then it was not
Sebastian’s too. Who ever was behind all of this knew what they were doing and
  was certainly a whole other level of danger, but no one got to do this to a
 demon and live to tell the story. So Sebastian decided, his master’s goal was
                                  no his own.
