"The setting: a dimly lit barn in an undisclosed location in the Deep South. It was two in the morning and the darkness was like a physical presence. The farm owner had left town for a few days, leaving me in charge of taking care of the animals. This was the opportunity I had been patiently awaiting for years. All was quiet as I entered the barn, but it would not remain that way for long. Unable to contain my desire, I approached the largest of the horses, Black Diamond, a stallion with a coat as black as the night. Black Diamond and I had always gotten along, much to the consternation of the owner. You see Black Diamond had the heart of a true wild stallion, and had never allowed anyone but me to so much as approach him. Not even I can say what he saw in me, but I knew that he was the one, and that this was our night. I presented myself to this exquisite example of the equine form, shivering as I watched slivers of starlight shimmer off of his black coat. He approached me without hesitation; he knew what I had come for. I was shocked as he became erect, for his was the largest horse cock I had ever seen. It is unlikely that you will believe me, but I swear upon my mother's grave that BD's horse cock was a full three feet in length, and had the girth of a grown man's forearm. The feeling of Black Diamond's monster horse cock penetrating my poop-chute was pure bliss. My sphincter contracted into a loving embrace of his shaft as he mounted me and mercilessly drove himself ever deeper into my welcoming caverns. While our love-making most likely only lasted for about thirty minutes, it felt like hours of heaven. Finally, with one last mighty thrust, Black Diamond released himself inside me; I let out a moan of pleasure as I felt the hot cream shoot forth into my intestine, gushing out around his already deflating cock. I lay on the barn floor in a state of happiness for a while before dressing myself, giving Black Diamond a loving pat on the snout, and returning home."
