My friend (38F) and I (31M) have set up the goal to get one of my fists inside of her.

This’s been one of the most amazing and rewarding experiences of our friendship. Fisting happens so slow and so much patience and trust is involved that it has strengthened our bond in incredible ways.

Now to the bottom of the matter: We’ve hit a wall at the point my knuckles are about to make it past her sphincter. Logically, we’ve used all the common sense measures to stretch her: not rushing things, tons (and I mean industrial amounts) of lube, different positions, etc; however, her anus still doesn’t want to give in.

We sense that she can still stretch more. We just haven’t figured out how to make it happen. My hands are average size, and she’s isn’t a tall girl, but definitely not petite. She’s always comfortable with anal and fitting largish/odd shaped stuff in there.

Any more experienced people who can give us advice? It’d be great if you actually have first hand experience at being fisted.
