Narrow hips

I've long wanted to be fisted in the arse but never really quite got beyond 5 fingers knuckle deep. The last two ladies to have tried have both said that they felt that I had plenty of stretch left but that my hips were very narrow and that was what was preventing them from getting all the way in.

I've never really heard of this before. Does anyone else have experience of this?

I guess the solution is to find someone with really small hands. I'm sure I will succeed in this one day.

I think I have the same problem. feels like the inside of my hips get in the way...

Finally, a lady with small hands and a lot of patience managed to get in wrist deep. Felt fantastic.
