HELP! Pussy fist without mercy!

My part-time master struck again. And that in the truest sense of the word, because in my second part of my new extreme series, a small attempt to play became bitterly serious. Painful and without mercy. Because what am I gonna do, all tied up and gagged? Your nerves will be challenged again this time when you have to watch it as I get a clenched fist pushed into my tight cunt for the very first time. You will experience these torments. But can you help me?
