Thanks to my mum, I had to sit with a tutor again and do some math. He was one of those typical teachers, totally uptight! When he was not there for a moment, I pulled my skirt up and played around with my pussy! I had no panties on anyway. The situation made me totally horny and I put it on! Just when I put my pen in my teen pussy he came back! Oh man that was the absolute kick! Can you imagine how awesome the feeling was when he slowly came closer?
