Sebastian Michaelis x Teenage Reader

A/N: Claude is human in this 

The contract should have ended decades ago, but Ciel had begged Sebastian to not take away his soul. 

But how it was time, Elizabeth had died, he had gotten his revenge, and most importantly you were old enough to run the business. 

So today, on the day were Sebastian is to eat Ciel's soul, Ciel and Y/N are walking in the woods. 

"Y/N, I want you to know that I love you." Ciel spoke looking at the trees. It was awkward for him to say outlook Ud, even if it was his daughter. 

"Me too, Daddy." You reply smiling at him. These were rare moments were you and father could be alone and talk. 

"If ever I'm away, or not here. I would like you to get married and take over the business." he spoke while looking at her. 

"But, Dad-" Y/N complains but, Ciel shakes his head. "No, please do this for me. And if Sebastian tells you to do something, do it." Ciel orders. Y/N nods. 

Then they recall the good moments they had. That night Sebastian ate Ciel's soul. This was the part that, he was supposed to leave, after all his duty was done. But he couldn't, he had grown to love Y/N, he cared for her, in a way that he would remain at her side, till her death. 

The following morning, Y/N's cries could be heard, and soon enough all the servants cried with her. Sebastian regretted it, and soon enough his funeral took place.  

He taught her everything there was to know, he also gave her advice on how to deal with a company. He took the role of Ciel, and had to answer questions such as:

"Sebastian, how are babies born?"

"Sebastian, do you think my bobbies will be as big as Ran Mao's?"

"Sebastian will we live forever happily ever after? ."

And when she was a teenager, she also asked questions.

"SEBASTIAN, BLOOD IS COMING OUT OF MY VAGINA!!!!"

"Sebastian, my stomach hurts!! Why was I born a girl?!"

"Sebastian, teach me how to put on my corset?"

And as she grew older, she met an Italian, Feliciano (Sorry, Feli I luv u!!) who had a company, and her hopes were to get married and expand the company. 

But he had different plans, you see;  back when Ciel was alive an Italian mob got him, and the leader was killed,and Feliciano was a relative. Now he wanted to avenge, Azzurro's death. He wanted to kill Ciel's daughter and Sebastian. But he didn't know that Sebastian was on his way. 

Currently, Y/N was tied to chair, while Feliciano was beating her, and telling her his story. 

"Azzurro was my older brother, and because of your father and his butler, he's dead!" he turns and slaps her. Just at that moment, a voice says, "Please refrain from touching, my Mistress."

Feliciano whirs around, and to his surprise finds a simple butler. At once he brings out his gun, and points at him, "Bastardo, you killed him!" he starts shooting at Sebastian's chest, and he falls to the ground; pretending to be dead. 

"It's your turn, Y/N." he points the gun at her, when he heards a gun cocking behind him.

"Back off or," he points the gun at Y/N's head, "I'll do it!" 

But before he could, Sebastian smiles and shoots him, killing him. 

"Thanks Sebastian, but how did you know where I was?" Y/N asks while Sebastian unties her. 

"Y/N, I could hear you besides you were with him." he answers while they walk out. 

"Thank you, Sebastian. I don't know what I would do without you." 

'Me neither' Thinks Sebastian as they enter the Phantomhive Manor.
