"What am I going to do?" She frets, as the horse approaches.
He nuzzled her neck and she jerked away, shaking her head. She kicked out at him, bucking. Her body was tense, her muscles flexed. She didn't want this. She was still human, and she was being taken advantage of. She wanted to fight it, to reject it. However, the more she fought it, the more the horse started to take over. She could feel the change happening, the mindless horse-like instincts taking hold of her brain. Her thoughts became foggy, her actions becoming automatic. The horse was starting to win the battle against her humanity, and soon it would be all gone.
The horse mounted her and began to thrust into her. At first, she hated it. She hated every second of it. She could feel the pain, the humiliation. However, as the horse continued to thrust into her, she started to feel something different. Something new. Something that made her forget about everything else.
The pleasure started to build inside her, overwhelming her senses. She couldn't help but moan and cry out in pleasure. She didn't know why she was feeling this way, but she couldn't deny it either. As the pleasure grew stronger, so did the desire to submit to the horse. She found herself wanting more, wanting to please him.
The horse continued to thrust into her, his pace quickening. Kat could feel the heat building inside her, the pleasure growing stronger. Suddenly, she felt the horse's cock throbbing inside her, filling her up completely. She screamed out in ecstasy as the horse ejaculated deep inside her, filling her up with his seed.
As the pleasure subsided, Kat found herself lying on the ground, panting. She felt drained, yet satisfied at the same time. The experience had been intense, overwhelming. She hadn't expected to enjoy it so much, but she couldn't deny that she had. The thought of submitting to the horse had been terrifying at first, but now she found herself looking forward to it. She was a horse now, and this was just part of the life she had chosen for herself.
