when i come home from high school my best friend decides to use me to FUCK

I have a best friend in my high school, she hinted that she would like to fuck me, but I thought she was joking, today we had to do a project together, we decided to do it at home, I arrived and there was a note from my parents saying that they would not be in home all afternoon, I told my friend, she convinced me to go to my room, and she took off all her clothes, I got hard, and we started fucking.
