maybe you should let her try fucking a man first at least like come on you know then after that maybe let me the man who fucks her first introduce her to it and then you and then she will be ok with it since your ok with it and since im the first guy she will be with she will do it. then ill leave and you 2 or 3 i mean because the dog will be happy. but lol no all joking aside maybe not. its really not for everyone and allthough we have these fantasies sometimes they are just that fantasies so keep them as such and i think your best option would be find a woman already into doing it and be with her.
