****** Sex, the Best Remedy for Frustration ******
by TheVillainousNoble
Summary
     A new case seemed so simple, yet it drove the human and the demon to
     the end of their wits.
   At first, it seemed like the case wouldn’t be as complicated. It was just
  something the Yard couldn’t solve on their own, but the culprit or culprits
were no match for the Queen’s Watchdog and his demon butler, correct? However,
 that perception changed the moment Ciel and Sebastian realized that they were
bing played with. The crimes were simple and silly on purpose, and they always
kept the two up on their feet. The moment they thought they caught the bastard
  or had time to sit down and think things over, something new happened. The
crimes ranged from pickpocket and burglary to various degrees of vandalism that
 even involved fires that threatened to burn the entire town to the ground. It
 would be some time that Ciel and Sebastian would figure out that the victims
     weren’t random but actually the whole town was the target. Right now,
     frustrated and exhausted, they were returning to their miserable inn.
The door slammed so hard it was a surprise it didn’t come off its hinges. Then
  it opened again, letting another figure into the room, one that thankfully
            closed the abused piece of wooden structure carefully.
“This bastard isn’t doing it for revenge, he’s having a bloody entertainment!”
Ciel’s anger was explosive while Sebastian’s, at the moment, was slowly coming
                              to a boiling point.
“Young Master,” the demon started, “some people simply enjoy watching the world
                                    burn.”
Ciel wouldn’t have been bothered as much by all the troubles the town was going
  through if the one they were after didn’t start targeting him. But with the
 Earl’s damn luck, he became the center of attention. Ciel came up to the desk
   in the middle of the room and gripped the sides. He breathed deeply, his
nostrils flaring. The only visible eye moved from side to side. With a growl of
 frustration, Ciel swept the candelabra off the desktop and the poor old thing
                    landed on the floor with a heavy thud.
  Sebastian watched his master. The state the boy was in could have dangerous
 consequences. He wasn’t thinking rationally right now, and if this continued,
 his health could get worse. The butler need to come up with a way to calm his
  master, and he did. Stepping forward, he placed his hands on the boy’s thin
shoulders. “Master.” He spoke. Ciel slowed his breathing and turned to face the
 demon. They looked into each other eyes, silent understanding passing between
 them. Then Sebastian took the top-hat off Ciel’s head, followed by the gloves
 and the coat. With a bi of hurry and less grace to his movements, he shrugged
off his own coat and tossed it to the side to land on a chair unceremoniously.
Large, slender hands cupped a small face, and thin lips crashed together. Ciel
  inhaled with his nose into the kiss, their eyes closing. Then he started to
    move toward the bed first to the side and then backwards, and Sebastian
                        followed, their kiss unbroken.
 CIel sat down onto the bed and Sebastian leaned in to be on his level. Their
 kiss grew more passionate and emotional as the demon knelt before his master
  and first worked on undoing the boy’s jacket, vest, and dress shirt, before
  loosing his own garments. Getting up, Sebastian pushed Ciel to lay down and
climbed on top of him. Their kiss lasted as Sebastian pulled apart Ciel’s dress
  shirt to bare his front. Then the demon’s hungry lips began to explore the
areas of the neck, collarbone, shoulders, chest, and abdomen. Ciel’s chest rose
                  and fell as he breathed deeply and quickly.
 His shorts were practically torn down his legs, an action at which he gasped.
With a growl, Sebastian worked to get Ciel’s heeled oxfords off his feet so he
 could pull the shorts off completely. Ciel rose his head, watching the demon.
Their eyes connected for a moment. But then Sebastian took Ciel’s cock into his
mouth and began to work the young organ. With a groan, the Earl leaned his head
            back onto the bed. Only his socks and garters remained.
  When Sebastian rose Ciel’s legs to the sides of his head, Ciel wrapped them
   around Sebastian to secure the demon at his crotch. He thrusted his hips,
   humping Sebastian’s face and the demon let him. He sat up a bit, one hand
coming to undo his pants and get to work on his own member while the other slid
down Ciel’s front to his head where he slipped his fingers under the eye patch
               and slid the garment off to reveal the contract.
As Ciel worked his mouth, Sebastian pumped his member erratically. With a cry,
   the teen finished himself into the man’s mouth. Sebastian didn’t swallow.
Instead, he held up Ciel with both his hands and moved lower. With his thumbs,
he spread the supple buttocks as he held up his master by the hips, and got to
            lubing him up with his tongue and the boy’s own semen.
“Ah!” Ciel gasped. He looked up at Sebastian and his right hand shot up to grip
  the demon’s hair. “Enough. I want it, now!” He ordered in a breathy voice.
Sebastian looked at Ciel for a moment, then he pulled back and laid his master
 down. From laying across the width of the bed, Sebastian moved his master to
lay properly along its length. As he sat between Ciel’s legs, Sebastian leaned
down and captured the boy’s little mouth in another deep kiss. A few more pumps
of his shaft and the butler positioned himself at his master’s entrance. With a
          single thrust, accompanied by a pair of grunts, he was in.
It took a moment to adjust their positions just a little for comfort. Ciel rose
 his hips, his behind fitting perfectly between Sebastian’s. Sebastian brought
   his arms to wrap around Ciel’s waist and then his hips began to move. The
 thrusts were hard and deep. Grunts and heavy breathing filled the air as the
  demon plowed his master’s hole. Ciel’s lower have bounced from the force of
  Sebastian’s thrusts and he wrapped his legs around the other’s hips to keep
                               himself in place.
Sebastian spread his legs, putting more weight onto Ciel and as a result being
 able to get deeper and give it to him harder. As his pace sped up, Sebastian
 rose his hands to grip the bed’s headboard. His own excitement spiked and he
 felt like he couldn’t keep his grip from getting harder. Cracks went through
the headboard at his strength and then the pace increased two fold. Ciel cried
  out and Sebastian moved from kissing his mouth to sucking his pulse point.
Ciel’s body rocks back and forth on the mattress from the force of Sebastian’s
thrusts and the bed banged against the wall. Wet, sloppy slaps of flesh against
 flesh sounded just as loud as the voices of the two lovers. One more thrust,
  harder and deeper than all the others, and the demon was filling the human
 under him with all of himself. In that moment, they were still. Their bodies
tense and breath heavy. It was the butler’s orgasm that pushed the master over
the edge and Ciel winced as his own hard flesh ejaculated with white streaks of
                 cum, twitching and throbbing with each spurt.
    The two laid there, slowly relaxing and coming down from their high of
 pleasure. Sebastian pulled out of Ciel, his cock hanging between his legs as
Ciel’s hole gaped and cum gushed onto the sheets. With a sigh, he laid down at
Ciel’s side and curled up, sliding an arm under Ciel and another over him in an
embrace. Ciel, laying on his back, placed his legs over Sebastian’s folded ones
and placed one arm over his front while another rested on the other’s on top of
  him. Sebastian placed his face in Ciel’s hair near his ear and proceeded to
             place small, lazy kisses onto the boy’s sweaty skin.
