Karyn and I were equally excited and nervous about the transformations class. We supposedly had a vial that
could transform a human into a horse. Based upon what my mother told us, we might have to demonstrate its
effectiveness. That was assuming we’d made it right in the first place.
The class was held in a normal looking science lab, but with one significant difference. One of the walls
could open to reveal a large fenced area outside. It was being closed as we entered the class. Before we
could sit down we were confronted by a friendly looking woman with long black hair who appeared to be in her
late 30s. “Karyn and Joey, how are you today?” she asked eagerly.
“Fine,” we answered simultaneously.
“Good to hear,” said the woman. “Are you two interested in volunteering your project today?”
I was too afraid to answer. I looked at Karyn. She glanced at me briefly but said, “Sure, why not?”
“Wonderful. Why don’t you give me your formula now so I can get it ready,” said the woman. Obviously she was
our teacher, but I was clueless as to her name. Karyn retrieved the formula from her purse and handed it to
the teacher. “Don’t worry,” she said. “I have full confidence and you two, and you know we don’t take
risks.” She walked to what seemed to be her own personal lab table and began to prepare our formula for
testing, I assumed.
Karyn and I took our seats. “What’s her name?” Karyn whispered to me.
“Get ready,” I said. I made the wish to know the names of both this teacher and our sex class teacher. We
got hit by the jolt again, but since we were both getting used to it by now, it didn’t have as much impact.
“Lori Youngblood. Professor Youngblood, I guess,” I said.
“Our sex teacher is named Chelsea Chester?” Karyn asked. “That sounds like a porn name.”
I looked at her suspiciously. “And you would know how?” I asked.
“Oh, shut up,” she said as she slapped me in the arm.
The class began with Prof. Youngblood addressing the class. She said, “So far in our studies we have
witnessed the transformation to a stag and to a bull. Today we are going to continue with a stallion. Joey
and Karyn have very generously volunteered their formula for examination and, if all goes well,
transformation. So let’s get right to it.”
She turned on a projector which showed an image of our formula under a microscope. She pointed out several
characteristics to the class, using a bunch of scientific terms that were strangely familiar to me. Part of
me said I shouldn’t have had a clue as to what the professor said, but somehow I knew exactly what she meant.
After Prof. Youngblood pointed out the characteristics of our formula, she removed it from the microscope and
put up a different slide. The second slide contained what she said was a scientifically approved formula for
human to horse transformations. She pointed out a few differences between ours and this one, mostly little
things that were results of the different conditions under which the formulas were created. She declared that
our formula was correct and could be used for demonstrations.
Prof. Youngblood returned to the front lab table and turned off the projector. She had a syringe with which
she loaded our formula. She looked at us and said, “Which one of you wants to show us your success?”
Karyn stood right up and said, “I will.”
I stood up beside her and said, with a worried look on my face, “Are you sure?”
“Positive,” she said with a grin. Then she whispered, “If anything goes wrong, you’ve got the ring to make it
right.”
“Sharing secrets are we?” Prof. Youngblood asked.
Karyn walked to the front of the class. “Oh, I just told her to stop being such a wuss,” she replied. This
drew laughter from everyone in the class.
“Joey, this is your formula, too, so please give your partner support,” Prof. Youngblood said as she motioned
for me to come to the front of the class. “Let’s get ready,” she said. She pressed a button on something
that looked like a remote control and the wall in the classroom opened. “Ready Karyn?” she asked.
Karyn took a deep breath. “Ready,” she said bravely.
Prof. Youngblood inserted the needle into Karyn’s arm and injected the formula. The effects took place rather
quickly. A fine layer of gray fur began to appear in several places on Karyn’s body. It grew thicker and
soon covered her entire body. A tail sprouted above her ass and grew in length. The professor asked her to
demonstrate her control of it and Karyn swished the tail back and forth.
The professor gave a kind of play by play account of Karyn’s transformation as it took place. The next change
was that Karyn’s pussy sealed. Once that happened her magnificent breasts receded into her body. Professor
Youngblood reminded us that all of our formulas, for this part of the class, were only for the male form of
our “less fortunate” species. She hinted that evolution had not been as kind to other animals as it had been
to us. Karyn looked worried at the loss of her breasts but the professor reassured her nothing was wrong.
More dramatic changes began now. Karyn’s cock changed in shape to resemble that of a horse. It also grew to
an incredible size that could almost touch her chest. Karyn could not help but let out a few moans as her
cock changed. Next Karyn’s ears changed as they grew more pointed and less rounded as compared to human ears.
They also increased in size.
The next change happened in Karyn’s feet. Her toes became covered in a black, enamel-like substance as they
slowly fused together and became hooves. Her fingers followed suit and they too fused together to become
front hooves. Her arms started to resemble the forelegs of a horse. Her body began to thicken and add muscle
in several areas, most noticeably in her ass.
Prof. Youngblood cautioned that the next part might cause some discomfort. Karyn’s body added muscle in the
upper parts of her body, while she was gradually forced into a four-legged position. I could see was in pain
as she gritted her teeth. Her body increased in overall size and she now looked completely like a horse
except for her face.
Her hair grew longer so that it resembled the mane of a horse. The last and most dramatic part of her change
started as her teeth grew larger and her face pushed out into a horse’s snout. She let out a few soft cries
of pain and by doing so made clear the change in her voice from human to horse. What started as “Aah’s”
became “Neigh’s.”
I was truly amazed. Where Karyn once stood there was now a powerful and graceful looking stallion. Prof.
Youngblood beckoned for Karyn to follow her to the outside area. Karyn complied with no difficulty. The
professor asked her to run in the enclosed area. Karyn appeared wobbly at first but soon gained control of
herself and galloped throughout the small field. She let out several cries which I interpreted to be happy in
nature.
After ten minutes of running around, Karyn returned to us. The professor asked Karyn if she was ready to
change back. Karyn appeared to shake her head “No,” but the professor insisted since the class was about to
end. She injected Karyn with what she said was an antidote to our formula. Within a few minutes Karyn was
again herself. The professor dismissed the class but asked the two of us to remain.
