Cassandra moaned softly as she ran her fingers along her slit. She moaned as she scrolled through her computer a moment, scrolling through a series of comics about a scientist turning a woman into a horse. It had ended with her being mounted by a stallion for breeding, while she had looked scared in the comic, the idea did nothing but excite Cassandra. She plunged her fingers into her pussy, imagining what it would be like to be that mare.
She thought about Rex, the farm's prize stud stallion. He was a large Arabian Stallion who they had bought years ago, and every time she had been close to him she felt aroused. She moaned as she imagined that she was a mare being mounted by Rex, she could almost feel the stallion's massive cock stretching her out.
"Fuck... yesss... Rex fuck me..." She moaned. "Breed me, make me your mare..."
She let out a cry of pleasure as she came hard. Her fantasy of the stallion letting out a whinny as he came hard, filling her imagined horse body with his seed. She fell back onto her bed, breathing heavily as she stared up at the ceiling. The fantasy of being turned into a mare had always excited her, even though she knew that it could never happen. That didn't change the excitement she felt whenever she imagined it.
She slowly got up, there wasn't any reason to keep fantasizing. Even with her parents gone she still needed to do her chores around the farm. Right now she had to go and check on the horses and make sure they were well fed. She stretched a bit as she slid on her t-shirt and blue jeans shorts. Maybe once she was done she could take Rex out for a ride, that was always fun after all and usually took her mind off whatever she was thinking about.
She headed out to the barn and started checking on the mares first. She poured some feed for them in the trough given that they needed to be kept separate from the stallions this time of year. They happily ate as she did what she could to get them all fed. When she finally reached Rex, she smiled as she fed him. She started rubbing his dark coat as she did, humming lightly to herself while the stallion was eating.
She looked between the stallion's hind legs, seeing that his shaft had slid out of its sheath. Maybe it was the smell of the mares, maybe it was her touch. But god it made her feel more aroused now. She rubbed her pussy through her the crotch of her shorts, soaking them a bit. She was having a hard time resisting the urge to touch his shaft, or even suck it. It was so large and enticing, especially as it throbbed as if with excitement.
She let out a moan, causing Rex to look at her surprised. So now she just had to decide what to do with him.
