A Dog Day

so my gf start to like hypnosis so she make me hear some files to try some stuff, but there was this file about becoming a dog with only one word but i didnt knew what word was it, so the first time she used it was on my house we were alone and we were making out until she whispered something on my ear, I dindt hear it well but I start to lick her like a dog after that I felt the need to take my clothes off so I did and keep licking her, I felt really aroused my cock was really hard and she was really excited too, I kept licking her and suddenly I bark I was really ashamed I try to cover my mouth but she didnt let me, she said "good boy" and i felt really good, my ass start to move from side to side and after that well I went full dog, she even put a collar on my neck it was really great but after that day she started to use that secret trigger more often and in public places we had to run to some public bathroom and hide until she return me to human one time I started barking at another dog, another day I was alone at home and she tarted asking really weird things and then she call me and she said the trigger through the phone, I had to wait until she arrive like a good dog and when she arrived I pounce at her and start licking her pussy really hard! I wanted to be a good dog.
