Going to the side of the house

I waited in front of that door. Usually she answered quickly so I knocked on the door again a bit harder. No response. I was confused so I checked the time on my phone and messaged my parents to make sure I was supposed to be there. They replied and said there was supposed to be a class, I shrugged and messaged them Just making sure.

I knocked on the door a third time and also sent a message on my phone to my tutor. I furrowed my brows and looked around. I wondered if there was a problem or if they were out, which was unusual because she never ever skipped a class.

I got a bit worried as I looked around the front of the house. I noticed the door to her backyard was opened so I took a look around to make sure no one was watching and walked through it. The side of the house was equally as dark as the front. There didn't seem to be anyone on this side of the house. I quickly crouched to make sure that no one could see through the windows and squished myself against the house.

I snuck through the passage towards the backyard. My heart started to pump as though it was a stealth game. I heard some noises near the back of the house, I guess it was some girl moaning and some thumping noise. I was already this far, I decided to go further.
