Fisting at my friend's house

I was invited by my friend to his house. We wanted to have a coffee together. I stayed alone for the while. I was so horny at that time. So, I started to play with my pussy. I wore a sexy red lingerie and high heels. Later I was fingering my asshole. It turnes me on so much, that I started to fist my asshole. I put a fist in my ass. At the end I cummed while fingering my pussy. I hope my friend did not see my masturbation.
