Did you know female horses greatly enjoy sexual interactions with humans? Male horses are actually legendarily bad at sex, they stick it in, cum in a few seconds, and that's that, he's done, horse clamjams and blue ovaries for days, and female horses can actually get frustrated by this.
Female horses ALSO have extremely fine motor control over their vaginas. They can open and close them with pretty good accuracy, and keep them closed tightly enough that nothing is going to accidentally slide in at low force allowances.
And so, once a female horse starts to understand the situation, after the first time or two, they will not only be receptive to advances made by humans, but will actually attempt to initiate on their own sometimes, with their vaginas flexed to exactly the scale that a human can fuck one and both sides achieve climax, or do whatever the human has done with the horse up to now.
Not only is it not hurting the horse, you literally couldn't get inside if the horse didn't want you to, since the muscles of a horse vagina are way stronger than the pressure the penis can handle, not to mention that if you're behind the horse, you actually are in the line of fire for getting the shit kicked out of you, and the horse may actively initiate the interaction if it's used to it and feeling particularly frustrated, intimate, or plain bored.
You're welcome.
