You're up to an amazing start thus far and might become the best director on this site in the future. I'm a huge fan of anal fisting and love that you do that in your scenes.
But I wanted to give you one piece of advice:
You need to cut your fingernails super short before anal fisting. Currently, there is still the possibility that you can hurt girls with your nails internally, which is why you always need to be very careful.
Once you've cut your nails, there will be no great danger of really hurting the girl (other than stretching, and your hand is probably slimmer than 2 cocks during dap). Which means you could do the fisting much more intensively, and also go wrist deep.
Keep up the great work, and I look forward to even wilder scenes once your nails are no risk anymore.
