heh, I'll join in this one. I've been fisted, but not by very large hands. In terms of length, I'll never understand it but I've taken just under 8 inches before. I was incredibly aroused, mind you. If I put 8 inches against my stomach, on a ruler, it looks impossible :/
Well, there's so many thick things to try. Large cuccumbers are ususally put to the test. I have a close friend that told me one day she was curious to see what was the thickest she could handle without feeling pain. She said it was a fairly thick shampoo bottle, but not one of the biggest ones, it was one of the medium sized ones. Those are still thicker than 99% of penises. I found that fascinating!
A guy I dated was 11 1/2 inches but sadly a bit thin. The widest guy I ever had was 4 inches long but must of been 4 inch round to he was very feeling both mouth and pussy
REALLY why would you want to put a fist in there. If you can take a fist no guys dick is worth danything to ya. If you got some guy or girl for that matter elbow deep in your pussy i say good luck cause you need it.
