Sneaking a boy in my grandma’s house

Date: 9/15/2019

I was spending the night at my grandma’s house and I had the whole house to myself and I started texting this boy and texted him that I was home alone and I asked if he can come over and texted back and said yeah. He came over and we started making out and I took him to the bedroom and he closed the door and locked it and we started back making out. We sat on the bed and I got on top and he started kissing on my neck and I was grinding on him and I felt his dick got hard and I was moaning. While he was kissing on my neck, the screen door was open and it closed and I heard my grandma’s voice and I started to panicking. (I forgot what happened to the rest)🤷🏾‍♀️
