When the mare returned, I could smell her musk as she sat on the low, padded bench and leaned back, spreading her legs apart as she did so. "Uh, u-huh, u-huh!" she grunted, pointing to my face and then between her slowly clenching thighs, where I could see moisture.
It was from there that the marvelous odor arose, and I eagerly buried my face in her crotch and licked at her slick lips with a tongue which seemed to be as long as needed. I found that I could penetrate her, then found the little mound within its folds which caused her to move her hips and push her vulva hard into my face and tongue, a sensation I greatly enjoyed. My rod had become steel hard and slick, long and big. After some time of my licking her quiff, she slid down from the bench and turned her extraordinarily broad, heavy ass to me, the cheeks parted and her lips open, wet, ready. I could see the slippery exudation sliding down her inner thighs, and licked at them for a moment or two until she grunted urgently. Her long arm reached back (she lay with her breasts on the bench, her head turned enough to see me) and pulled at my pulsing rod to help me into her as she bent back from her knees toward me.
With but slight resistance I slid into her throbbing vagina, her juices anointing it nicely. We seemed to be growing larger, for I pushed slowly into her for some distance, and met but tender resistance until I finally found my pubic bone tight against her hairy buttocks. I began a slow and very sensuous pumping, feeling my balls begin to draw up as her vagina tightened and relaxed around my stem. Briefly I reached for her breasts and fondled them. They, oddly, seemed to diminish, but then we two began to feel a new sensation-at least, I did-an urgent tickling, an itch, all along the length of our contact.
The mare was moaning now, and her crupper thumped me in the belly with more and more force as she must have approached her climax. I could feel myself becoming more and more deliberately powerful in my own movements, my whole huge body straining to ejaculate; with a jolt at the base of my tremendously long spine, a powerful shove and a "hu-u-uh!" from us both, I spurted glob after glob of semen into her willing receptacle. I felt huge, bigger than I had ever been, and my body felt longer and somehow heavier.
"Urh, urh, u-huh-u-huh!" she groaned. I could do nothing but repeat that phrase, and lick a little tiredly at the flow of juices from her gaskin. I had to bend my torso a good bit to reach that tasty spot. I was dazed more than I had been before our joining, and staggered on my four hooves to stand quietly against one padded wall while she almost bounced to her four feet and looked fondly at me. I saw that her body had matured, that now she had the elongated barrel, withers, crupper and tail of a mare, and the torso, breasts, face and head of a woman, the same woman who had led me to this stable. I had the same long horse's body, with my lower torso melding into it just above where my pubic bone had been. I could feel my immense penis and balls hanging down inside my stifles.
Just then, our mutual admiration was interrupted by the appearance of the lord of the manor. He peered at us over the half door-I tried to ask him . . . what? I could not speak and the wish died in a moment- and said, as though to himself, "Damn' good looking stud, that. Esera, you should have a beautiful colt from that breeding! Be a good runner."
The mare-"Esera" was apparently her name-smiled but said nothing, for she was now as much a part of this man's herd as I! I wondered briefly if she had been a good runner, or would be again. She had been a damn good mate! I had understood the man, but I discovered that not one of us could talk. In fact, I was very muzzy in my thinking, and after a while I gave up, and soon lost all memory of who I was-I had always been a centaur! I was able to wonder occasionally if Esera would have a filly, and if she would be as good as her mother. Esera was a superlative mate for an equine!
