Jess neighed over and over trying desperately to get Mary's attention. She was now in a sense of urgency as she could feel the stallion's now erect member slap against her underside as he tried to find his way into her. But finally Jess saw Mary comming towards her in a light jog.
Jess was starting to feel a little relieved that Mary was comming, but Mary's jog was now slowing to a brisk walk. "Why is Mary walking?", Jess began to question. But finally Mary approached Jess and spoke,"Oh hey Jess, looks like our new visitor found you before I could get here. Too bad I can't do anything now, we sold alot of our horse handling equipment, and you guys are a little too big for me. Anyways, this does fit into things I had planned for you anyways."
Jess then gave Mary the "What the Hell?" stare to show her confusion as to what her friend was saying. "Oh, I guess I should explain", Mary started,"You see, I remember that you are on your 3 weeks of vaction from your broker job, and I thought it would be a nice get-away for you to come here and spend sometime as a horse. I came up with the idea while we were riding over here, and I made some calls to arrange for things here. However, I didn't know that we got this stallion from the nearby farm, but it all works out. You see, I was actually planning on taking the vials and making myself a stallion, but we already have one now. So I'm going to leave you two alone now, but I will be back in a few hours once I get somethings from my house, later."
And with that, Mary was gone. Jess, unfortunatly, didn't have much time to brood, as the stallion finally found her openning. In one great thrust, he pushed himself all the way in. Jess had never felt so full. Sure she had been with men before, but nothing this big. Now in a state of disbelief, she let the stallion have his way with her. In and out, he thrusted again and again. After a short time Jess's body began to rock with his motions, increasing the movement between the two horses. More and more, until he finally stopped and exploded inside of her.
After the stallion dismounted her, Jess went back out into the corral. She couldn't believe what had just happened, she was mated with a horse, as a horse. Even more disturbing was that Mary didn't help her, and she found that a small part of her actually liked it. She, at first wanted to be a horse, but now she really felt as if she were one. The more and more she thought about it, the more she found she was having trouble thinking in general. It was as if her whole mind was simplifing.
She didn't like what was happening. First she became a horse. Then she was mated like a horse. Now she was starting to think like a horse. She knew she should have felt fear or anger at this new development, but all she felt was indifferent. And even so, new insticts began to drive her body. Finally she just let go and embraced her new mind. She didn't have much choice anyways, with Mary wanting to keep her like this for awhile she may as well experience it fully.
Now with her mind altered, she started back for the back of the barn again. Her new insticts were telling her it was still time for mating, and that's what she was going to do.
