"I had always wanted to try it but never had the courage to ask my wife to do it to me, so when the nurse said she needed to put her fist inside my ass I was more than happy to let her do so. She explained she would start off with a couple of fingers and then insert more until she had her fist inside me. She said I would most probably leak some precum or even have an orgasm and ejaculate, she said this was normal. The best bit about it all was my wife was in the room watching, I just hope she was learning something and want to try it when we get home."
