Any stories of cucks being spanked by bulls?

I'm very keen to hear real-life experiences of cucks being spanked by bulls whilst tied up, before, after or during the bull pleasuring the girl. Or any video links to scenes like this
I spank wives and husbands. I can give sensual spanking to wives, even make them cum.
Hubbies get it hard till my cocks in their mouth. End of.

Check out the thread "Merry Christmas Darling" its pretty long and I think it should be among the "best topics" sections. The first couple pages are hot to this. As far as videos I haven't seen too many.
