Tattoo artist Fucked me Hard before the session!

I was recommended this tattoo artist as a professional who does tattoos on intimate places. I trusted him and came to get a tattoo on a hole in the ass . But I was very embarrassed and tickled. He started playing with my pussy and said it was to make me relax. But suddenly he put his dick on me and started fucking me hard, I asked what he was doing! She said that I need to finish and then I can get a tattoo. He also said it was standard procedure...
