The satisfying part of having sex with an animal is watching the animal experiencing pleasure and then your own pleasure which comes from doing something you find pleasurable.
I have seen dozens of hours of female zoo porn (admittedly at usually 8x speed
) but the problem of it being short is the fact that almost nobody understands how dogs work.
Very often you see a dog jump on a woman, hump her a few times and jump off and this repeats 5-8 times.
The reason is NOBODY IS HOLDING THE KNOT. Normally a female dog would hold the knot with a ring muscle in the vagina. HUMAN WOMEN DO NOT HAVE THIS MUSCLE. So you have to grab the knot and apply pressure.
If you fail to do that, the dog will jump off and the knot will slip out which is to be expected since he wants to turn around and there is no ring muscle.
You are not supposed to hold the legs or the tail, you have to hold the knot. Almost nobody does that and that very nicely shows the utter lack of animal knowledge non-zoo fetishists have compared to zoophiles.
