Sebastian's sister (ciel x reader)

Y/n, Sebastian's sister. She calls him bastard bassy, why? Cause he is "one hell of a bastard brother!" With Y/n being in sent to another world than that bastard brother, she became loyal to her master, ticci toby, ( @galaxyp1ctur3s , I made this part for you.) and his wife. Samantha. She normally bakes with Sammy (yes Y/n calls Samantha Sammy) but when that bastard (I keep using that because he is one hell of a butler!) and ciel apear, it becomes one hell of an annoying ride.
