This is an old post, but it popped up on a Google search.
I happen to be in the same situation.
As you play with cuckolding lifestyle, limits often tend to be pushed... and then suddenly you find yourself 'far out'.
I wonder if that's what make some people do illegal things

Oh luckily my fetish is just cuckold...

Going in the direction of being humiliated, I also 'suddenly' fantasize being dominated by the bull.
It wasn't always like that.
I have taken my wife's piss and I have rimmed her... but now I would like to take it a step further.
However my wife isn't too keen about it, but she'll have it in mind she told me.
In an even more extreme fantasy I would beg to dring and eat whatever they are having.
By that I mean exactly the same they had... after it have been through them that is.
Now that's difficult to find anywhere on the internet, so here it is in writing instead.
