My girlfriend & I both do it after my hubby has been in our arses. Its not for everyone but we find it super sexy with a hint of filth. Mmm
I'm not sure I understand the question. Please be more descriptive. But obviously the answer will be no.
After a real thorough butt hole washing and clean out,.... Ass hole licking is one if the best experiences. I had a GF that refused anal fucking. Then I had a plan. I began to lick everything between her legs. Then when she was real relaxed I got some warm coconut oil that tastes real good. I applied it to the entire area and continued licking. She got so relaxed and began moaning. I then began licking inside the ass hole and it began releasing its grip. Then my tongue went all the way in and I continued that for a while. It seemed she had no idea I was inside but she said it feels great. Before you know it I had one finger in her ass hole with more massage motion. Then two fingers then my dick. She could not believe that there was no pain at all. Ass fucking then became her default sex activity because she loved it so much.
