The screen flickered and then spelled out, "Supplement 20".

Odd thought Jeff but what of his wish to be all fuzzy and warm he remembered from his cousin's younger days, and of there prize pony. The wild and sensual thought of being and feeling like that little animal had long since captivated Jeff's imagination.

As the green-lighted ray shined a circle on the floor Jeff still clothed and filled with desire stepped into the spotlight.

Standing bathed in the green glow of the ray emitter Jeff saw the monitor screen flash, go black, and then light up with a red background. His eyesight seemed to be getting out of focus but with the colored background, he still could read the larger words.

FURRY TRANSFORMATIONS

PONY:
GENDER: MALE
BREED: HAFLINGER
AGE: FIVE YEARS OLD (MATURE)

SECTION "B" RULE 9
SELECTION # 20

What Jeff could read seemed just what he thought would make him a sensual and thrilling time as something he'd fancied for several years.

It was then his vision blurred and the room filled with dozens of strange but easily noted smells. As he sniffed the air, his nose and mouth were growing into a pony muzzle. His eye spread apart as his skull grew to pony shape.

Neck gained length, mass, and thickened of solid muscles. Shoulders began to grow tearing Jeff's shirt and popping the buttons in all directions.

The expanding of his chest and lengthening of his backbone all went so fast and smooth he barely noticed. It was as the change moved into his lower back, butt, groin, and thighs he had his first real touch of pain.

A sharp pain not to be toyed with his tail jutted out of above his rump and the growing of the tail hairs each gave him a pricking pain. As it flourished long and pony like thick he began to sway it over a new and sensual rump.

Pleased with himself for having chosen to become like cousin Steve's pet pony Jeff stood trying to balance himself in an upright position.

"What the...Jeff what are you doing?" came a frightened question from his older sister as she walked into the room.

Jeff's clothing lay on the floor but to any common person what still stood under the green rays of the emitter was a pony with still human feet.

Tina stood for a moment and then plopped her cute butt into the chair next to the hard working computer. She eyed her changing brother and then turned to look at the computer screen. Reading as she well could that say large printed information she stopped, and then began to read the finer print with obvious interest.

A few minutes of study, had meanwhile Jeff completed in form and stood before his sister a mature five-year-old stallion Haflinger pony.

As the emitter light faded out Jeff snorted feeling his new self from many new and strange ways. Flicking his, tail the coarse hairs made a comforted rustling sound whiles he patiently for his sister to look at him once more.

Tina was quite busy reading the program of Furry Transformations. A lip nibble to his knee from Jeff did the trick and she turned to face her younger now pony brother.

A loud whinny came from Jeff's pony mouth as his hot breath touched Tina's bear leg.

"Neat program, I hope you read the disclaimer well before doing this thing? I suspect not as you do not ever read a book from cover to cover! You remind me of our cousin Steve's pony, right?" asked Tina.

A nod of the pony head agreed with his sister's comment.

"You really liked that pony didn't you? Well I think you are going to learn to like it for quite a while as you selected the Section "B" which inset the program's rule number 9. If you had read the rules of the program you might have taken note to this section as when you quickly typed in a big 20, you ordered the program to extend its general settings from either an hour, or days, to weeks, and maybe months. You my dear pony brother chose the 20 and along with it came the word FIXED. If you read the captions on the word fixed you would see it means as like you were born this way!" said Tina to Jeff.

A soft whinny from Jeff as he shivered to think he might remain a pony his whole life long. The thought was at the same time something to find its delight and there in front of sister Tina, as Jeff got painfully erect.

Jeff felt as wonderfully alive as his mind floated about locked into the head of a blonde haired Haflinger pony. He turned in circles eyeing him as then paying no attention to his sister, Tina.

"You do like it, don't you my stupid brother!" said Tina as actually making fun of him.

Ignoring Tina had become a test of Jeff male will, as she could come up with the most tacky comments, at the right times.

Standing up and reaching a hand out, Tina tussled the mane atop Jeff's pony head.

"You know something brother pony of mine, as a pony you make a striking form of one made male and for a reason. Say I help you along with being this pony form, and take you to live on the Killingsworth Farm. John Killingsworth is an ole' school chum, he would take you in, and as such a prime stallion would breed you! That was your original thought I imagine when you began this fool idea. Silly brother, sex and your predilection for wanting and having sex with girls has brought you to become a new species. Oh, you thought I did not know of your late night romps, well I followed you a couple of times." said Tina, hands on hips and standing before Jeff's pony face.

A moment of absolute silence went by, and then Jeff reached his head out forward. A black skinned pony muzzle poked into Tina's hot and tight groin. A sniff in drew her scent, making Tina shiver.

"Damn you, your more a pervert as a pony than when you where my insane brother!" screamed Tina.

"Hey calm down up there!" called out a warning from their Mom.

"Damn, she's home, what am I going to do with your sorry hide?" wondered Tina not wishing her mother to know and see Jeff as he was, a horny stud.

Tina left Jeff to stand and find his maleness as a new thrill, she asking her mother for something she knew they had none in the house, pleading for Mom to get her some from a nearby store.

A mother’s love is boundless, and once the dear woman had driven out of sight, Tina went to get Jeff and bring him to the Killingsworth farm.

As she entered the bedroom, Jeff stood there masturbating, doing it in true pony style.

A moment after Tina entered the room; Jeff blew his first big load of pony stallion semen. It spewed forth like water from a garden hose. The white cum and thick globs of pony semen reminded Tina of their mother making Tapioca pudding. The puddle of cum looked like the creamy pudding, as globs of equine semen resembled the rounded pearls of the sweet Tapioca.

A red scarf made for a halter, as Tina looped it about the pony neck, dragging the young stud out of his bedroom and to the back lawn where he began to graze. The instincts were making their presence known to Jeff; he gave in quickly to them after having masturbated like a pony.

The finding of a rope in the garage made it and easy job to move the degrading brother to become a part of some farm scene. When Tina presented to John her friend the pony, she made up a story of it just wandering about the back lawn, as if it were lost.

Days later when the local police began a search for Jeff, he being missing for more than three days, Tina went to visit her brother. She along with John Killingsworth went to the stables, and there when they arrived, the stable groom had Jeff already hard at his duty, he humping away, his black Haflinger pony shaft sunk deep into the vulva of a pretty mare.

The stallion stopped his thrusting when he saw Tina standing near the corral fence. He whinnied to her his greeting, then turned toward the mare, and began to hump in earnest.

John remarked how the pony stallion kept itself in rather exceptional manners of personal hygiene, he waiting until morning to crap and urinate outside of his stall. He made mention of the pony stallion and his mating sessions, how after the mating he would like to have his tool washed and oiled.

Tina and John became good friends, and after a couple of years, they got married.

Jeff remained as a Haflinger pony stallion and stud, doing what then came naturally to him, he is the proud sire of hundreds of bright and strangely smart foals. Never again did anyone see Jeff in his human form, but lived the life of a stallion Haflinger pony. He let Tina ride him, the two won many ribbons at fairs and rodeo events.

The computer and its special adapted green ray, Tina kept it for future uses, as she used it on certain men who would dare or try to force their sensual ways upon a woman of proper breeding.
