Brian felt renewed of purpose and had the promise that his days of being a stallion horse were numbered. Llandros said they would meet within a week, that being seven days, as he felt sure those day would for him move by swiftly.
Beginning his newly assigned duties, Tinker was eager to do his assignment, he keeping all the male herd sires cocks as washed clean and doctored for their bettered ability to breed. The rather ignorant youth saw his task as a labor of love, he having often enough sat and caressed a sheath to urge on an erection, and then to stroke it, suckle it, until he caught a mouth filled with beastly spunk.
Mason was there but not able to make any of his usual as unkindly remarks. Although he was of mind and mouth kept occupied, after being magically merged with the rump end of a Percheron mare still in heat. His duties were new to him if a bit gross. As he settled into being physically the sex organs of a mare, his guts would he feel grumbling, they churning of want for the mare to mate. He had still his tongue to taste and help invading cocks to feel an added tickling sensation when they were thrust past nervous winking lips.
Awake and in constant actions, he knew of what Llandros said about the term of his serving, and being serviced. He did not relish with any delight his manner of purpose, as his tongue tasted what to him was as vile, disgusting, and what if he could he would spit it out of his vulva lips.
Mason had not long to wait before he felt the weight of some stud about to mate with his mare self.
Remembering of what Llandros said when he cursed Mason, he being devoid of sight, no nose to smell of anything, no need for ears either, but of his mouth he would gain knowledge as to what stallion cock tasted like. Brian was willing then to help Mason learn what a naturally filthy horse cock tasted like, as he, Brian a stallion had not yet for many weeks enjoyed the tender attentions of young Tinker.
Brian felt he had renewed reason to mate the mare, if not from the sheer pleasures he being a stallion felt from mating, He would be giving nasty Mason some of his own sense of being degraded. So the fence-post of a Percheron horse cock did poke its erect head at the black winking lips of what set waiting to being fulfilled.
Mason cringed from the sensation of a stiff cock pressing past as opening the mouth of the mare vagina. He wriggled as the cock-head and its bulk cock body was pushed along what Mason felt was his throat. As with the entering the mare vagina, the cock was leaking slick pre, it too having a flavor to offend Mason.
When Brian felt his greater satisfaction he had reached bottom with his great cock, he began then thrusting. His cock thrusting action made Mason feel as if his throat was gagged, he gagging because of the sheer size cock he had inside what was his changed self. As torture to Mason, the feeling as gagged to being choked, his tongue feeling and having to taste the vileness of the intruded cock. The flakes of dried mung stuck to his tongue, the mung softening from the vaginal juices, tended to give forth the flavors of what made mung as vile. Mason learned then the tastes of stallion semen, of mare vaginal juice, added to the flavors the cock sweat from an overly warmed cock skin, encrusted too with sand and dust from Brian standing when masturbating or toying with his maleness.
Three years of this his lifestyle of indignity..., and then when Mason thought his plight would could not get worse, as Brian fired his load of spunk, the possibility of a pregnancy meant he being the womb and vagina of the mare would need to deal with the birthing of a foal, having to taste then blood and birthing fluids, "Oh yuck!"
