Horny 18 Year Old Big Step-sister Helps Me Study Part 3

I came home with great news today, and I was so excited to tell Holli my big step-sister about the 'A' I got on my Soviet History test! She was extremely stoked for me, and said she had something for me since I did so well on my test. I was surprised when she got on her knees in front of me and started unbuttoning my jeans. She was down for more than a hand job this time. My step-sister loves me so much she sucked my cock like a champ and let me cream pie her pretty little 18 year old mouth. I love my big step-sis so much!
