Sarah crept towards the barn quietly. It wouldn't do to be caught by one of the ranch
hands. The barn was a good ways off, but the cool night air didn't bother Sarah in the
least. As she got closer she could hear whinnies, grunts and neighs from inside, and the
lights were on as well. Clearly something was going on. Sneaking closer she was
overwhelmed by the scent of cinnamon. It reminded her of her dream and she
unconsciously stroked herself as she thought of Joe ... and Genie. Shaking herself she
pulled her hand away and peaked into the barn.

Inside the stall doors were all open. Several horse heads turned to look at her from
around the doors or over the sides of the stalls, but in the back she could make out the
rear end of a horse sticking out of the stall into the hallway. Grunts emanated from the
stall, and then suddenly two loud whinnies. One sounded suspiciously like Thunder, but
the other was softer and quieter, like a human mimicking a whinny. Sarah ran to the stall
and looked in.

There, on her knees with her face level with Thunder's massive shaft and covered in horse
cum sat Carla. More shocking, her body seemed to have undergone a strange
metamorphosis. Her ears were pointed and twitched on the top of her head. Her face had
pushed out into a small muzzle and a even as Sarah watched her inhumanly long tongue
cleaned Thunder's stallionhood. Carla's feet had changed into digigrade hooves with a
light dusting of brown fur hanging over them that matched her hair. A brown tail flicked
behind her like a happy puppy's.

"Therrra" Carla slurred, unused to her longer tongue. "Therra, es thooo goood." Sarah
could only stand in shock. Her friend and older sister had changed half way into a horse
and was giving blowjobs to the real horses. What was going on!?! And why did it turn
Sarah on so much? She pulled her hand away from her crotch. "I need... you need... help.
You need help Carla." She almost had to force the words out. The need, the yearning to
join Carla tugged at her. She imagined what she would do with Joe if he had a nice big
jucy NO! Sarah shook her head. Something was doing this, tempting her. She had to get
away, get help. She turned to run, but was caught up in big furry arms.

She looked up into the face of her captor and saw Genie?! Only then did she notice the
changes to the horses. Each had become like a centaur, their equine bodies below, but the
upper body looked like what Carla was becoming. A furry humanlike torso with an
expressive equine head. Two three fingered hands gripped Sarah gently. "Stay." Genie
said with a pleading look. "Friend". The equitaur turned her around and hugged her close.
Carla stood and walked up to them. Cum still dripping from her face and body. "Therra
need halp?"

"Yesss." Sarah whispered. A glimmer of hope rising. Carla nodded to Genie, who held
Sarah so that her pussy was near level with Carla's head. Carla placed a hand on each of
Sarah's legs and leaned in, pushing her snout into Sarah's pussy and licking with her long
tongue. "Oh gods" Sarah exclaimed. Carla continued to eat her out until Sarah came with
monster truck force. Genie gently set her down, but Sarah found she couldn't stand on her
new hooves and knelt. "mmmmm, mmoar" she moaned, her tongue starting to protrude
from her mouth. "Mine" Genie said and moved over her. His long shaft now hung
invitingly in front of Sarah. She could smell the delicious cinnamon scent and eagerly
latched onto it. Carla helped her at first, but as Sarah's muzzle grew she could take the
whole thing until Genie came and covered her in buckets of sticky semen.

Carla helped her new sister to her feet. Sarah looked at her thankfully, and noticed that
Carla had grown a furry pelt that matched Thunder's. "You, Thunder's?" "Yes. You
Genie's" Sarah shivered in pleasure. She was owned, a mare in service to her stallion. She
looked down and saw she had a pelt that matched Genie's dun coat, and hugged him.
"Mine" he said again, and gently stroked her mane. "Yours" She murred, rubbing her face
into his flank.
