While shooting some videos with Nuria she noticed how large my hands were. Nuria explained that she like anal fisting and how much she loved challenging herself sexually. She was a bit shy and confessed she had never tried to take a fist the size of mine ever before. I asked her if she would be interested in trying to fit my fist in her ass and with a big devilish smile she said YES! I grabbed the camera and the lube haha. Part2- After spending some time warming Nuria up, I could tell she was ready. I started off slowly with a few fingers and to my surprise her asshole was opening up with little resistance. As I put more and more fingers in then more and more of my hand, I could tell she was shocked to see her asshole not struggling to take my fist. Every time she took a breath and contracted I could feel my first getting pulled in further. Before she knew it my entire fist was inside her asshole. The session ended perfectly when she told me to push and pull my first harder and faster she ended up squirting in one final orgasm from the anal challenge.
