Alyssa was left awestruck by her change. A horses asshole? How? Was whatever happened to Kayla contagious? She could hardly think, she needed to leave. "I-I need to go." She hurriedly dressed while trying to ignore the warmth in her anus, and the pleasant feeling of it rubbing against her pants. Kayla felt guilty, she'd let her new anatomy get the best of her. "Wait! Alyssa I'm sorry. We can figure this out!" But Alyssa hurried out of the barn and walked briskly over to her car, somewhat awkwardly as she tried to adjust to the sensation of her horse donut rubbing against her pants.
As Alyssa drove from the ranch, Kayla was left alone in the barn, her cock still beating against her soft belly. "Why won't you stop!?" She whined to her throbbing cock. As much as she wanted to follow Alyssa, she realized that her lack of experience with her new form might make that difficult. Besides, Alyssa probably wanted to be alone and she almost certainly wanted nothing to do with Kayla. The incredibly horny centaur needed to do something though. "I can't leave like this...but I don't want to give in." Kayla was left with a dilemma.
Alyssa was similarly confused about her next course of action. On one hand she wanted to go home and relax, but did she really want to deal with her family right now? On the other hand she felt like she might need medical attention. But where would she go? She'd be labeled a freak at a hospital! And she couldn't exactly go to the vet either. But another, more pressing need was arising. Heat began to bloom throughout her body, and her new butthole began to throb and wink. "Why am I so horny!?" She exclaimed in frustration. She could feel her panties being soaked and her mind kept wandering back to her encounter with Kayla, how amazing it had felt. Before she knew it her hand had crept into her pants and began playing with her soaking pussy. The heat wouldn't stop. She had to do something. Should she go back to Kayla? Or a nearby farm?
Kayla was dealing with a similar frustration, her erect horse cock would not calm down. She had waited for an hour for the lust to subside but it wouldn't. She'd begun slightly grinding her member into a wooden gate in the barn. "I..can't take it!" She needed to do something. Should she leave? Maybe try to find Alyssa? Just the thought of Alyssa made her cock jump, causing her to moan. Her lust might override her reasoning. Maybe she should deal with it now? The idea of mating with one of the horses on the ranch was intoxicating. Her asshole throbbed and her cock wept pre. She wanted to fuck. Maybe a sink her length into a warm, wet mare. Or maybe the hot tight ass of a stallion. At the same time the thought of a stallion taking her anal virginity was just as attractive.
Neither of them could wait any longer. They had to take action.
