This Question Is For A Female To Answer. I Really

This question is for a female to answer. I really want to give a dog a blowjob but I'm a male. I saw my gfriend do it and I now I wan to see what it's like. But also I want to make the dog cum. I get so horny from the thought that I would want to film it. Antways. An I normal? Should I pursue this fantasy? Thankful for your time.
