She’s my slave

I woke up alex sneaking into the house after she went out with her boyfriend! She begged me not to tell on her and she even promised to do anything I told her to do! I laughed and she begged me. Told me to give her some crazy thing to do and she would do it! She would be my slave for a month! I smiled and told her to get naked. She slipped her clothes off and I could see the hickies on her inner thighs! I told her to spread her legs open, I wanted to see her freshly fucked pussy. She sat down on the bed and spread her legs wide open. She even had a hicky on her swollen clitty! I touched her and she was still sensitive. I smiled and looked at her. I’m sure she thought I was going to eat her pussy. She should have known better! I pushed my blankets down showing off my bald pussy. I told her to eat me till her hair was soaking wet from my pussy juices! She went to town on my pussy! I laid there pushing her face into my pussy, thinking about what else I could make my slutty sister do!
