After the talk with Principal Cartwright Jen decided to slip out at lunch and hit the movie theater because she certainly neither understood nor cared what sort of craziness was going on at school. The movie was uneventful mediocre popcorn fare and immediately as it ended she hurried to be on time to her small part time job helping out the few horses at a nearby stable.
She always started with Shy Bob, as she called the stallion. She gently trotted him out of his usual spot and mounted him. She rubbed his neck gently and told him, "Don't worry, we're just going to go for a short walk. We won't do anything you don't want to do.", knowing full well that she was supposed to lead him to a gallop and push him a bit to make sure he stays in shape.
As they rode she noticed that curious pressure in her pants that she had felt earlier in the day. Without slowing down she simply unbuttoned her jeans and kept riding. The sensations she felt were an interesting mixture of pain when Shy Bob hit rocky rough spots and pleasure from his normal rhythmic pace. Eventually she let him take a quick breather and she finally looked down.
It was obvious to her that what had shot out of her jeans was the familiar looking shaft of Shy Bob. It was an obvious match to the fur right below that made up Shy Bob's backside. She reined him in and gently dismounted to examine his crotch. She could tell quite easily that the stable's only stallion was now showcasing a bald human pussy of surprising age.
She lead Shy Bob back to the stable, idly stroking the monstrosity between her legs, and for the first time truly contemplated what was causing all of the changes around her. Realizing that she really was the new possessor of Shy Bob's prized stallion-hood was the revelation she had missed earlier in the day about how complicit she really must be in the day's events. She had no idea what the trigger was, but now she was starting to suspect that their was one.
As they neared the stable Jen started to notice the most wonderful scent. It smelled like hazel and a field full of flowers, like dawn's dew and lilac, like a jasmine and the warmth of lovely sunset. The closer they got the more vivid the metaphors wafting through her head. After making sure that Shy Bob was all set for the evening she went to investigate that smell. She followed the scent to a horse she had nicknamed Lady Jezebelle, for how much she seemed to enjoy a good romp in the hay with Shy Bob.
It slowly dawned on her that it was the smell of Jezebelle in heat as the stallion now in her very quickly aroused as she approached. Thinking with not much more than the cock between her legs Jen grabbed a nearby step stool, that they used to clean the horses or help young kids mount the horses, and proceeded to mount Lady Jezebelle in a way that Jen had never imagined possible for her to experience.
She felt so much power and strength radiating around her crotch. Jezebelle, as was her nature, took great pleasure from experience, over-acting her enjoyment of the act. Jezebelle acted so well that Jen couldn't help but release her load quite early.
It took Jen a small bit to recover from the explosion of pleasure that she felt and the memories of the experience. But eventually she had to make her way home.
The spent cock, nestled in its sheath, strained her panties and jeans and poked up a bit into her shirt, but it was not anywhere near as noticeable.
On the drive home she couldn't help but reminisce about the experience and found herself getting aroused and excited just thinking about it on the drive. At light she unbuttoned her jeans again and let the stallion cock flop out. It rubbed oddly against the bottom of the steering column with the car's vibrations, but she didn't want her parents to get angry if she was late again so she just tried to ignore it. A couple speed bumps finished the job the car's vibrations and her own imagination started, causing her to explode another load all over her car's rubber floor mat. The pleasure almost caused her to hit a mailbox, but this time she was slightly more prepared for it and slammed the break in time.
She couldn't believe that she had three male orgasms in the same school day, much less that two of them were with poor Shy Bob's pride and joy. She buttoned her jeans back up, doing her best to hide the sheath and turned into her driveway...
