And in the perfect training position for stretching.Angrywife said:
I have found the easiest and fastest way to get them stretched is to form a duck bill with your hand with your thumb folded into to palm of your hand and then pull a condom over your hand - Lube it up and start inserting it.
When you get to the knuckles she pushes out with her anal muscles and you push in - this will release her sphincter muscles and your entire hand should just glide in.
Once her anus closes round your wrist you need to edge it in and out to get the muscles used to the stretch.
4 - 5 sessions a week, she will be able to easily accomodate your fist in a month
Hope to see some pics of your progression
