Your demon: A contract with limits
Ten minutes had passed and Sébastian didn't waste the chance to prepare your lunch and serve it to the kitchen's table, covered by a tray lid so it would remain warm for you to eat whenever you decide you want to.
The demon walked over to the backyard door and let it open for your dog to come in. As he went back to clean some dishes he glared in disgust when your dog finally entered the house. His ears perked a bit when he caught the sound of your footsteps walking down the stairs.
Alas, your attention was now completely focused on your dog who jumped with his front feet on your shoulders and licked your cheek, causing you to laugh and giggle the whole time.
Sébastian swore that if it wasn't for your sake and only, this filthy creature would be thrown out to the streets.
"Down Dingo, down now" You ordered the Husky with a steady tone and so he obeyed, making his way into the living room where his bed was.
You turned to face your demon but your cheek made sudden contact against a bare chest which was Sébastian's of course. Then his arms snaked around your waist bringing you closer. You looked up to him and smiled sweetly. "Sébastian...."
Half-lidden reddish-orange eyes stared down at you lovingly. He cupped both sides of your face and began to rub your cheeks playfully.
"Hey...stop that!" You grabbed his larger hands to yours and looked up at him with a serious expression. "I don't want you to go"
He gave you a sad smile while stroking your hair. "Hopefully I won't be that long my love" His head leaned down to rub his nose against yours gently.
"But you always return at night time. What's that surprise you told me about? Please tell me" You spoke softly, due to the warm feeling of his lips against your forehead.
"I'll be back very soon. Don't forget to eat your lunch, yes kitten?" He purred to your ear and before you knew it he pulled you in for a rough-passionate kiss. And just like that, he was gone. Leaving you a flustered mess.
Sebastian sneaked into the mansion and started on his butler duties like every day. He went to the servants and let them know they'd be off their duties for today and they could take the time to rest. With breakfast and tea already made he entered his master's bedroom, he let the wheeled table aside for a moment and walked straight to the double window to yank open the curtains and let the sunlight fill the room.
Ciel's eyes cracked open and let a yaw out as his body slowly rise and stretched out his arms, now sitting on the bed with his back against the pillows.
"Good morning young master, did you sleep well last night?" Sebastian asked while filling his master's fine porcelain cup with freshly made tea, serving it to him gracefully.
The boy's slender fingers curled around the cup's handle as he brought it close to his face and took a sip from the hot delicious liquid. "Don't act as if you care, it disgusts me. And your efforts to avoid the main topic of what we have to discuss are utterly pathetic. You sneaked away from the mansion...again" Young lord murmured the word 'again' under his teeth in an aggressive tone. "I've been told you ordered the rest of the servants to guard me and the estate from intruders when this was YOUR task in the first place. It's the 13th time you did so for this month and to be honest it started to get on my nerves. Tell me Sebastian do you plan to go against our contract?"
The butler's surprised expression slowly faded away, his eyes were closed and a devilish smirk took its place across his youthful face. "Not at all my lord, however, we have to make a serious conversion together about some changes we might have to make for our contract to remain and for the success of both yours and my goals"
Ciel's single eye never left its gaze from Sebastian's reddish-orange ones. "What the hell do you-!"
"Now now sir, there is no need to raise your voice like that, I am more than certain we'll come to a proper agreement but I am afraid your today's lessons cannot wait. We can talk during your lunchtime if that would be alright with you of course" The butler remained silent for a moment and waited patiently for his master to act.
Finally, Ciel looked away and let out a deep sigh. "Fine" He got off the bed and stood up straight while Sebastian was undressing and changed him into a fine new outfit.
Some hours passed and now it was time for Ciel's lunch. The young lord was at his studies, reading and sighting up a bunch of papers until the familiar knock from the other side of the door took his attention. "Enter" He spoke coldly and let the papers down against the wooden surface of his office.
Sebastian walked into his master's studies and closed the door behind him. With slow steps, he approached Ciel's office, now standing right before him, and left the silver tray with the food in front of his master's view. "My lord" His tone was smooth and calm as he made a small bow with his hand placed over his heart.
The boy held the fork between his fingers before he took a bite of rose beef and peals. "Speak and you better explain everything"
"As you wish sir, I've already told you about Miss Y\N and the relationship we developed during the 8 previous months"
"Don't tell me things I am already well aware of" Ciel commented back but stopped abruptly as his mind came up with a new possible situation, his hands hit hard to the office, and stood up from his seat. "What in the devil do want to say?!' He shouted out angrily.
Sebastian didn't lose the chance to get off his tie and unbutton his white shirt, his gloved hands grabbed both the shirt's sides exposing most of his chest where your shared silver seal would remain for eternity. With closed eyes and a genuinely happy smile, he chuckled in amusement. His master's pure shocked face was more than entertaining to say the very least.
A shadow appeared on the boy's gaze as he lowered his head a bit. "BASTARD!" In a flash, the plate with his lunch was thrown across the demon's face.
His face and hair were now all dirty and a complete mess, his hands pulled over his chest just in time to cover your shared seal from getting dirty. The demon let out a deep sigh. "Alas, I knew such a reaction couldn't be avoided from you master. However, you must calm yourself this doesn't change our contract. I will help you get your revenge and I will take your soul in exchange. My Y\N's case is different in all matters. You see, it turns out she was meant to be my mate and eternal companion. With this seal, I became responsible for her precious soul, so when the time came for her to pass away the reapers wouldn't have the right to take her soul to paradise or hell either. I will put her soul into new bodies as the centuries pass so, she will always remain alive and we'll be together forever. That was one of my promises to her. All I want to ask are some favors from you for both of the contracts between you, me, and her to work out in harmony" He explained calmly with his hands now behind his back.
Ciel was taking deep breaths in a desperate try to calm himself down. "What favors? And just to be clear, does she know about our contract?"
"Yes she does, I told her all about it. I couldn't hide the truth from my one and only mate after all. But fear not she's not going to give out our secrets, she's loyal enough as much as I am to her. About the favors, I wanted to ask...I would be more than grateful if you'd be so kind as to hire her as an employee here at the mansion. She's a very capable gardener and will be a great help to me compared to the mess those three are causing me all the time. I will be able to keep an eye on her and make sure she's safe. The second favor is that from now on I'd like to have 2 free hours during the day and a new bedroom I can share with her. That will be all my lord, I am sure this won't be any trouble compared to your generosity and kind nature"
"And what if I refuse all that nonsense you requested? Do not forget you acted behind my back and got against our contract no matter if you want to admit it or not"
Sebastian smiled mostly to himself and glanced back at his master with a confident gaze. "Then you have my wish for a happy future. Time was never my enemy and no matter how much time it will take me, I will find another tasteful meal to satisfy my stomach. You thought you could do whatever you desired with me, that I was your pawn, your tool to fight any block on your way and that's true but not without any limits. As a demon, I will never abandon my mate and I will stay by her side at all costs. The final decision is completely for you to take if you will agree or refuse my requests....so, what will you do, master?" The devil gave out a nasty smile, allowing his sharp teeth and fangs to be barely visible and his eyes to turn that pink-fuchsia of his.
You were eating peacefully your lunch, you spared a bit to Dingo as well when you heard the knocking on the front door. Sebastian who had already unlocked and made his way inside with the extra pair of keys you had given him walked towards you and lifted you from your seat to his arms. "My surprise to you awaits, shall we go now kitten?" He questioned with his forehead against yours.
