I started getting into Anal with a UTR provider a few months ago and now can't get enough of it. It seems it's the same with her.
I believe she had some past experience but even so the first time we were both very nervous for both of us.
What i learned is in this thread for most part. Patience, lube, an organ that is not very large and a willingness to give it a try are all required to get one initiated.
Have fun and if you ever need an experienced hand at this lets hook up.
