"Absolutely not!" The blue-eyed boy with an eye-patch shouted at the insistent demonic butler. "How many times do I have to tell you?! NO CATS!"
"But, my young master! They're precious!" The butler pouted.
"And I'm allergic! You know that already!" The boy snapped in reply, annoyed. The butler sighed heavily. The boy then replied, quite sarcastically, "If you were to remove the allergy, you can have cats."
The butler's dejected look slightly brightened, though he hid it from his young Lord, Ciel. "If I were to remove your allergy, I could have several cats?" The young master snorted.
"As many as you want, Sebastian." He replied sarcastically, fully believing that such a feat was impossible, even for his demonic charge. As the butler walked off to prepare dinner, the boy muttered under his breath, "Damn demon."
Sebastian watched as his young master slept with a smirk on his face. "Just remove your allergy, young master?" He pulled off the glove on his left hand with a smirk, revealing their contract symbol. "You underestimate me." The butler chuckled quietly as he pointed at his young master's forehead. The candles in the entire manor went out for a few seconds before relighting. The red-eyed butler smirked once more as he pulled his glove back on with his teeth while he left the mansion to find his feline friends.
Soft prodding on his stomach and a certain smirking butler informing him it was time to wake up was what our special young master awoke to the following morning. Ciel Phantomhive mumbled something incohesive as he attempted to continue sleeping, only to be thwarted by his demon butler, who opened the curtains and began telling him what today would bring. Slowly, Ciel sat up and looked down to his stomach...
... To find that a furry black cat was snuggling comfortable onto his stomach.
"... Sebastian...?"
"Yes, my lord?" Sebastian smirked.
"... Why is there a cat in my bed?"
"You said that if I removed your allergy to cats, I may have as many cats that you want, my lord. I have fulfilled that deal." The demon smiled at his young master.
"... You removed my allergy?" Ciel said more than asked in disbelief, now staring at the dozens of cats in his room.
"Yes, young master."
Groaning, Ciel layed back down and pulled a pillow over his face.
"Are you attempting to suffocate yourself, my lord?" Sebastian teased.
"Shut up!"
Ciel attempted to think of a way out of this, to no avail.
"Of course, they will not be seen by any guests, will not be in the kitchen, nor their fur in any of the food or drinks." Sebastian added.
Ciel sighed. A deal was a deal, after all. Sadly, Ciel's stubborn honor would not allow him to back out of this deal, as Sebastian would point out if he attempted. Reluctantly, he began to force himself to begin getting used to the cats and pet the one on his stomach.
