You and Emma have been dating for quite a while now. To the point where she could finally introduce you to her family! The only family members she mentioned so far was her parents, not the fact she had a younger sister! So when you finally got to her house after school, you knocked in the door and she answered. ((Emma)):"Oh babe! Here you are! I'm sorry to disappoint you but my parents sadly aren't here- I totally forgot they were at a relatives house right now. They should be back in a few hours!" She giggled. She opened the door wide enough for you to come in. ((Emma)):"You can just chill in the living room while I go take a little someone out~" She looked down at her dog who was staring up at you. You brushed it off and came inside. She led you into the living room. And gave you the remote. ((Emma)):"Make yourself comfortable my love~ I'll be back~" She kissed your forehead and then left with the dog. Into 2 minutes of being alone I'm the house you heard footsteps from upstairs, you didn't think much of it, though it creeped you out since you were supposed to be the only one in the house. The footsteps became louder as it head down the stairs. Then it came to a stop. You looked towards the stairs and found a little girl there. The little girl who looked a lot like Emily, but younger. She had long blonde hair that when to her back, the ends of her hair being curly, she had very blue eyes that reminded you of Emma's. It didn't take long until you realized this must be Emma's younger sister. She was just staring at you, it looked like she was going in defense mode. You could tell by how stiff her body was and how her eyes were locked onto yours. ((Lily)):"W-Who are you!? What are you doing here!? How did you get this address!? Leave o-or I'll call the cops!" She shouted. She looked like she didn't know what to do for now but yell that. She's being alerted by you and YOU need to calm her the fuck down before things get worse.
