I have a very sexy girlfriend that likes to have sex. One day, my math teacher asked me to come to her place to "talk". I went home with her, and she made me lay down on her couch. She went in her bedroom, changed, and came out wearing a black bra. She was also wearing a thong. She pulled my pants and shirt off so I was in my boxers. She told me to undress her. After I did that, we started kissing. Eventually, we fell on her bed and had the best anal sex ever.
