One of them. Dipper gleeful x reader

Should i change? Nope

   "Hey y/n....... Me and Mabel gotta go. We'll be back soon though babe!" Dipper calls running out the door.
   Finally they are gone! You can go see will.
   You go to the closet and slowly turn the nob.
   You see him sitting there, still sobbing just as last time.
   "H-hi y/n." He stuttered as he stopped sobbing, "I can't believe y-you actually c-came back."
   He was actually smiling.
   "Of course will why wouldn't I?" You say sitting by him.
   "Normally, any of Mistress and master's friends beat me. They never come and be with me." Will says tearing up.
   "Oh will, don't worry. I-i won't let them hurt you anymore." You say confidently ,"Where do they keep the key to this thing?"
   "Well Mistress you could use your amulet." Will says pointing to the necklace.
   "Oh yea!" You say holding it.
   You rub it and your eyes glow turquoise just like the gem. The Chains are flouted and broken.
   "Oh mistress! Thank you so very much!" He says hugging you.
   "Ummm..... Your welcome?"
   "Y/n?!" You head Mabel's piercing voice behind you.
   "I ummm found this guy and thought he was intruding. So I decided to get him outta here. I was just about to get my dagger out actually." You say very convincingly.
   "Oh. Well I guess it's time I tell you he isn't an intruder. He is a demon. He is our slave! I hope you love having people do shit for you, cause he will do it all!" Mabel said outing an arm around you.
   That's when you snap back into the blood crazy girl you are.
   "So can, I like, cut him?" You ask with an evil grin.
   "Sure!" Mabel says as you both pull out your daggers.
   "B-but y/n what abou-"
   "Oh hush! You thought I was actually gonna be your friend? Ha! Not even flies would be your friend!" You say not being able to control yourself.
   You stick the knife in his upper bicep and cut really deep.
   The hot blood comes pouring down and lands on the floor in a red stream.
   "Now will that teach you a lesson?!" You yell at the sobbing demon.
   "Y-y-yes m-mistress!" He cries.
   "Good you pathetic slob!" You yell kicking the door closed.
   "What was all the commotion?" Asked dipper as you walk upstairs to your rooms.
   "Oh just had y/n do her first beating on will! She did very well." Mabel exclaimed looking proud.
   "Oh wonderful! How was it?" Dipper said to you.
   "It was just beautiful!" You say cheery,"It's just wonderful to have a slave to cut open when he misbehaves!"
   "Oh how I agree sister dear!" Mabel exclaims.
   "Yes!" Dipper cheers," watch this. WILL GET US SOME TEA!" He screamed.
   In seconds the boy appeared with 3 cups of tea, one blueberry Mabel's favorite, one lavender dippers favorite , and one cherry vanilla your favorite.
   "What took you so long?!" Dipper yelled at the demon.
   "YEA WHATS THE BIG IDEA?!" You yelled along with Mabel.
   You and dipper took turns slapping him.
   "Oh y/n I think you and I will be more close than me and candy and Grenda!" Mabel exclaims once the demon runs back to his closet.
   "Oh yes Mabel, I'm sure!" You agree crossing your legs in a chair.
