Spencer Reid x fem!teen reader

imagine: coming home from school expecting Spencer but finding the team

You had just gotten to the apartment complex from school. All you wanted to do was change your clothes, raid the kitchen, turn on a movie and crash on the couch til Spencer got home to order takeout.
You stepped in front of the door and stuck your key in and opened the door. Right away after you dropped your bag next to the door you noticed Spencer's bag. 'oh he's already home..sweet makes things a whole lot easier'. Considering he was already home you call out to him, "Spence I'm home and I'm stealing your clothes so don't question it" (idk if yall do this but i do when i take my dads clothes sometimes soo)
Not listening for a response you make you way towards his room grabbing a sweater before making your way to your room. After you change you go to step 2 of your plan, raid the kitchen.
Stepping out of your room you finally register the different voices in the room. Six different ones and you only recognized two out of them. Walking into the kitchen everything immediately got quiet and all eyes fell on you. Scanning the faces of the people in the room you were correct in the two you knew. Your brother and JJ all the others you guessed was the rest if the team. JJ was the first to break the silence with a smile.
"Y/n its been so long how have you been?" she asked.
You shot a smile her way "Well you would know how I've been if you visited more often" you replied glaring playfully. She chuckled at your answer "Well in my defense, Henry is in that phase where he only wants mommy" she replied sassily.
You had dramatically gasped and looked over at Spencer with a look of fake hurt. "Spencer did you hear her ridiculous excuse, using my baby as a reason to keep away from me. I feel betrayed." you dramatically exclaimed. Spencer decided to play along with your little act and looked at JJ offended.
"I can't believe you JJ. How dare you use precious Henry as an excuse." Spencer exclaimed holding back a smile. After this everyone watching had burst into laughter. Even stone cold Hotch let out a small chuckle. It was when everyone stopped laughing did Spencer decide to introduce everyone.
"Guys this y/n my younger sister, y/n this is Aaron Hotchner, Emily Printess, David Rossi, Derek Morgan and Penelope Garcia." You smiled at everyone and shook their hands respectively while Penelope pulled you into a hug. Derek then asked the question all of them were wondering.
"So pretty boy, care to tell us why all of us except JJ hasn't met her before?"
Before Spencer could get a word out you interrupted him.
"Well JJ knows me because who do you think babysits while her and Will are at work and or on a date. You guys never met me because there was never the right moment. It was either I had school or Spence had work. And frankly when we both have off days we like to spend it together because we rarely get the chance to hang out anymore." you finished then turning around to get to the freezer.
The team looked at each other satisfied with that answer. "Now if thats all the questions you have I hear my couch calling my name and this ice cream tub has my name written all over it." you go to sit on the couch but are stopped when Spencer grabs your collar.
"Did you have anything else to eat today?"
"...yeah"
"Y/n I want you to be honest with me so I will ask again. Did you eat anything else?" He gave you a pointed look.
You looked down "No I forgot money to go buy lunch" He took the ice cream causing you to pout. The team was watching the scene in amusement. A high schooler was pouting over ice cream getting scolded by an FBI profiler. Oh how they couldn't wait to get to know you.
