Sandy, as all his friends called him was flying into Africa; a trip planned and looked forward to these many months back at college. A student of science he was soon to get a degree in Biology. Now though he was looking forward to three weeks of fun and friendship as he visited his Father's new African expedition. Dr. Francis L. Chapman, Sandy’s father, had for the past ten years working on a special project, "The Nunji Tribe and their plant enzyme medicines."

As Sandy got off the plane, he faced the ninety plus degree heat and his Father waving. Son and Father, both family and the best of friends had many of the same interests. It was his Father who first interested Sandy in coming out to visit, and promised him the time of his life!

A five hour ride by Jeep had Sandy unloading his gear and rubbing his rear from bumps, bumps, and more bumps. His Dad was a great scientist but had no ability as a cab driver. Many a time back at home Sandy would drive Dad to and from his meetings, less there be another accident.

That evening the air was still hot and humid as the stench of sweaty men and their animals mixed to make Sandy pinch his nose. A young Nunji girl named Saysa watched Sandy try to become accustom of his new surroundings. One long hot night and a little sleep had Sandy walking about the camp blurry eyed.

Come breakfast time and to his surprise came this pretty, black, native girl named Saysa presented herself as a guide for him on his first day. She soon introduced herself and the two found many things in common. An almost instant friendship bloomed making Sandy feel as if Saysa was flirting with him. A suggesting wave from Dad authorized him to go off with his new girlfriend, Saysa.

Many things he did see the day until well after sundown the two sauntered into camp. Sandy's Father took exception to the late return as the prowling animals of the plains do their killing after dark.

Worse yet was Saysa's own Father being at the encampment and his words and actions told much. A rough and hard man took Saysa's arm and tossing her into the dusty ground. A kick and then two had her crying as Sandy began to defend his new friend.

"No stop don't confront him!' said Saysa to Sandy before he could get close.

Doctor Chapman grabbed Sandy's arm and holding him back, as he whispered that Saysa be granted to the hands of her Father.

"Sandy, Son there are many things one need learn about living on the African plains. Another is to understand the rules of society which the natives made many centuries ago and live by even today. Saysa's Father is the one man I don't want to lose his trust of me or my Son. He is the Medicine Man who can teach me the most about there healing ways. I warn you as well that this Man has in his bag of tricks some things that I a doctor find to be, well bordering on witchcraft, of the most blackest of black. In a grove of trees one night I watched a young boy maybe nine years old. He was trussed up off the ground by leather straps. The medicine Man danced about tossing a gray powder over the boy and calling on some spirits. I do not believe is spirits but the powder was some chemical he had mixed for just this reason. A boy charged with stealing, condemned, he stood sentenced to a different way of life by the medicine man for his foolishness. He screamed bloody murder till coated in the powder. Suddenly, he calmed down and just blinked and ogled the Medicine Man. I watched as the boy's figure, legs, and arms became changed from human form and limbs to those of a male goat. The boy hung there until morning, when Saysa and two other girls came to take him down and wash off the gray powder. I then stood dumbfounded as they attached a rein or rope to the goat and took him away." said Doctor Chapman to his son.

"Nice story Pop!" said Sandy with a silly grin.

"No Sandy, true as true can be I hope you take great care about being around Saysa, she's her Father's youngest and he watches over her like a Hawk!" replied the Doctor.

"Dad, I've heard such stories but most are on late night television!' said Sandy still not believing his Dad.

They parted company as the Doctor heard of some problem in the research tent. Sandy took this to be a good time to talk with Saysa and he headed off to the native village.

Half way to the village the light from a roaring campfire took Sandy's attention. Turning from the well worn path he headed across the grassy plain for the fire and a loud group of voices. As he crept up close and looked past a felled old tree he saw to his terror Saysa.

"You have disgraced yourself with this young man, the famous Doctor's Son! said Saysa's Father as the group of black men sat about in a circle making moaning sounds together.

Saysa held out her hands as if to plead for mercy. Sandy was almost ready to jump into the ring, grab Saysa, and run for the far hills. Then he stopped as her Father took a clay pitcher and doused it over Saysa's head making her scream.

The moaning suddenly stopped. All eyes were on Saysa as she screamed one long terrorized yell and then went silent.

Sandy was half ready to jump up and run when a hand grabbed his shoulder.

"Dad! Saysa! her Father tossed a pitcher of stuff and........!" Sandy began to tell what he'd seen.

Saysa looked up to her friend and screamed some awful pain filled words. Her Father the Medicine Man also looked up and motioned to the Doctor and Sandy to come.

The circle of old men stood up but did not take their eyes off of Saysa.

"But Dad he was......!" Sandy began to say again.

"Come Son, there are some people I guess in this world who must be taught the laws men live by!" said the Doctor as he pushed Sandy down to the circle.

Sandy stood looking at Saysa who by know was hunched down and looking at him rather oddly. The Medicine Man stood looking the Doctor into his eyes, as if he had him in some native mind control. Sandy stood there, not at all was he affected by the black Man's stare.

"Hey we were just friends, nothing bad happened she could tell you!" spouted Sandy in her defense.

Doctor Chapman stepped back away from Sandy as two men took hold of him and tied his wrists together. A long leather strap was tied to his wrists and in a second or two he was trussed up like his Father told of some other young male.

Knives bright and sharp cut away Sandy's clothing leaving him scared, naked, and every erect.

"I trust you not boy, it is for those who live in our village I keep a strict hand over them! Saysa was not born as what you knew of her, she was taken from the plains and allowed to live among us either until she’d forget her beastly ways, or as with you make them as a curse. You made her sin, your sexual ways blackened her soul; against me. Now as she is and the both of you shall be then under my curse. The black powder here has been handed down the ages giving power to men like myself over those so scared, those feeling it bow to me and beg for mercy!" said the Medicine Man.

"Dad, do something! I, we did nothing but walk and talk, we never had seeeeeeeex!" screamed Sandy in a panic.

Sandy’s dad stood there beside his son and kept his eyes set looking straight ahead, he saying nothing!

"Your father is as the others as he's seen and known what the powders do to a body. He took a walk with me some months ago and begged to learn the medicines which I hold. Oh I thought little of him but he did well! I blessed him will a powder my own Father showed me some thirty years now past. It is Zebra powder and once donned upon a body changes it to male or female Zebra. Your Father spent what he said was a wondrous day and two terror-filled nights being a male Zebra. He learned, Saysa tried to learn, you shall learn from Saysa!" said the Medicine Man as he tossed a black powder over a screaming college student.

Sifting the powder over Sandy’s head, it drifted down clinging to his sweaty skin. Burning pains made Sandy cries to his father turn into horrid screams of a youth in pure agony. Eyes welled up with tears as his pain only increased. He looked over to see Saysa in a moment of compassion for the one there who really knew him. Blurry tear drenched eyes gawked at her seeing standing below him a young female nanny goat. The Medicine Man made a motion with one hand and a man knelt down beginning to milk the bleating goat.

"You now see Saysa as she was born to be, a goat! Born a goat of her mother a breeder goat, she so beautiful that I made of her a human and part of my family these seven years as if my daughter. Now due to your disgrace of her, she must be now an animal she was once. You, Sandy, son of Doctor Chapman will not be her consort! Your body will change, growing much larger similar in species but wild where she is of the tame animals. An Ibex buck is what is for you, to be in the wild and at risk of those predators upon the open plains.

A curse enough to be the Ibex animal but for you I wish Sandy to remember who and what he was before becoming the animal. You will learn quickly to graze and be alert. Your days as a buck will bring on the maddening drives for mating. As Saysa remembers you for a time, you will remember her, but being what you are, as a wild beast, you may never come in contact with her again!" explained the Medicine Man.

"NO, oh God no you cannot do this to me! Dad, Father do something!" screamed Sandy as his body began to fade from the human race..

"I am sorry you came here Son, it would have been better for you, never to have come here! I will do as the Medicine man tells me to do! I want to learn his medicines, the strange powers they control and I am willing to trade even my son for bettering the realm of science. You and your new life will be the savior of those who might die without this new knowledge!" said Sandy’s dad, the Doctor.

Sandy tried to respond his tongue felt very strange as if now long and thin. He strained to focus his eyes on those walking away or even Saysa. Fire like burning pain was searing his skin black and making it into the hide of an Ibex. As if adding insult to injury he felt hands touching his maleness. Then such as spike of pain, as the magical hands jammed his penis up into his gut. Feeling his fingers and toes lose their sense of touch, becoming stiff, and hard as they changed into hooves, black cloven hooves. He cried out but the only sound he could muster as a high pitch bleat, of a young ram. Black hairs sprouted out of changing skin, upon this he cried out for his father again. The scream and those that followed had the singular tone of a male Ibex at the height of being a horny male. Struggling at his bonds, he gained another male erection. The erection doing something even Sandy never expected, he and his long black cock slapped at furry flanks. Sensation, the essence of being an animal and learning to trust what he would smell, hear, see, and feel. The touch of his long erection to furry hide gave Sandy the desire to become an Ibex sire. Suddenly such passion in his chest and lust like he had never known coming from his groin, he could hardly wait until the morning when they would come to cut his bonds and let a male Ibex run free.

The circle of black men began to wander off as Sandy hung there changing. The Medicine Man put a rope about Saysa's neck and tied her to a nearby post. Then he stepped over to Sandy's Father and taking his hand he said, "My good Doctor fear not for the young man will soon feel the desire to run free and join his kind. He shall remember everything that has happened on this night and for some time to come those memories will burn into his brain. The one thing that will free him from the grief of his dishonored action will be after he has mated for three years.

To see him struggle, the instincts are in him to run free and as well he will long to mate. I suspect he will be a good sire of many of his kind. Be pleased for him that he even in disgrace can contribute to the way of life here on the plains of Africa.

For you your Sandy is a worthy trade as I shall be the guide to learning the powers of our special life saving and future changing powders. I know your willingness to understand the powders, and promise made to assure now that your son Sandy, will not interfere in our mutual trust, and future relationship!" said the Medicine man.

A sad and still distressed father stood there looking past the Medicine man speaking to him, he seeing what was becoming of his son, he being so much an animal even his mother could not recognize him. Eyes met of a father and his animal son, as Sandy bleated his then Ibex cry, he could but watch as his human father turned his back to Sandy and with the learned tribal Medicine man at his side, he walked out of sight.

More changing continued, as now Sandy was alone, trussed up and standing on the hind legs of the Ibex he was soon to become. The aching want building in him and all the new sensations had Sandy wild with passion. He could see Saysa back in her animal self, tied to a post. His love felt for her was fading fast, somehow he knew she could not hold him inside her, and he needed badly to find a mate like him, of his kind, he feeling more proud to be as an Ibex. He could not stop the lust and building passions was beginning to make him long for being wholly like a true born animal. Imagined sensations of when he were mounted and mating with an Ibex female, the thinking of it as much was driving onward the transformation.

Like massive hands molding his head and the bones in his body, Sandy stood there feeling massive strength, new agility, and what felt most delightful came as rounds and rounds of self induced, masturbation.

Later in the early morning light, Sandy watched the Medicine Man stride proudly up to an almost completely changed mature male Ibex. A smile came over his face and from his left pocket came a small bottle of elixir. Reaching up he poured it down the length of Sandy's very erect, black cock and in and around his sheath. The slow flowing liquid spread slowly over the arched shaft. Sandy could only watch and twitch from the tickling sensation. Tilting his Ibex head for a better view, Sandy strained to lick the end, of his two-foot long cock.

"You are now as you shall remain young one, a male Ibex, a true to form sire! Your memories of what you were shall continue through three mating seasons and as the sexual urges continue, your human mind will wear quite thin. You I would expect shall become a herd member and on your third anniversary of this night will become a common and ignorant Ibex buck! Your curse will be a blessing to the Doctor, as he will carry our understanding of the African herbs back to his home.

Now I want you to pay close attention, be you to try to act human or maybe communicate with any authority during the coming three years, I promise to make your father pay a horrible price. He would receive some special perfumed powder, it will make of your father the best learned Zebra stud any zoo would be proud to own, trust me boy!" chided the Medicine Man.

Months later, as the mostly unrecognized doctor became world renown, the royalties pouring into his bank account, there arrived an envelope in his daily mail. Opening it with wonder as the return address was to a postal box in a small town in the western region of the Serengeti plains.

Inside the envelope was a photo, and with it a small hand written note.

Good day sir doctor,

I and those of our village have discovered new pleasures from the wealth you sent and we received. I expect you to keep your part of the bargain promise, as for your son, he is actively doing what to him is becoming more his nature every day here on the plains. As a vivid reminder of him and our bargain, I wish to assure you that the ability to send your son to live on the Serengeti Park remains as one of my special abilities, one that if I do not get more new wealth, the same and similar could be as real for you as well!
