Ultimately Megan couldn’t overcome her body’s urges. She turned around obediently so that her rear-end was facing the excited new stallion. She then bowed her head and raised her tail as she submitted to Abby’s advances. She felt guilty for having betrayed Alan, but the heat within her loins had become truly unbearable. She tried to convince herself that he would have done the same if he were in her position.
Sadly, Alan wasn’t in Megan’s position. Instead he had to watch as the woman who he thought was the love of his life presented herself to this complete stranger. He couldn’t believe that she could be such a little bitch. He had lost his humanity for her and this was how she was repaying him!
However, although Megan could sense Alan’s pain, she had made up her mind. It wasn’t long before she felt Abby’s nose beneath her tail as he breathed in her intoxicating scent. He took a few long breaths as he inhaled her captivating aroma as it wafted out of her engorged pussy.
Things quickly ramped up a gear when Abby started putting his tongue to good use. Megan loved the feeling of the slippery appendage as it wriggled around inside her, teasing her vagina’s sensitive inner walls as it went. She couldn’t hold back a pleasurable whinny as her excitement built.
She desperately hoped that Alan didn’t take things too badly, after all this was a practical solution to her problem, nothing personal. At least, that’s what she told herself.
The licking continued for a few minutes before Abby withdrew, content that his mare was ready for him. Her juices now dribbled out between her dark pussy lips as her clit winked in and out rhythmically. Her vagina looked large and welcoming, and so the eager stud got down to business.
Alan watched in despair as Abby reared up and landed on his lover’s back. The pair then shuffled around as they lined everything up. By this point Alan had given up trying to prevent their coupling. He tried to convince himself that it was the horse instincts that had corrupted Megan, and that their bond was still strong. However, this did nothing to cheer Alan up as he watched his lover getting it off with this newcomer.
As Alan looked on in dismay, Abby decided to finish what he had started. He began prodding with his hard member as he sought Megan’s sopping wet folds. It took a few misses before he struck gold. Megan whinnied in pleasure as she felt Abby’s mushroom-shaped tip spreading her vagina open before it started to sink into her inch by inch. Mare juices were forced out around the thick penis as it burrowed inside Megan’s tight pussy.
Soon Abby’s member was completely enveloped within Megan’s wet folds. The mare’s vaginal muscles hugged his shaft tightly, allowing her to feel every square inch as it nestled inside her warm passage. Abby paused for a moment, clearly enjoying being inside this sexy mare.
However, things did eventually pick up again. Abby began to rock forwards and backwards as his penis slid in and out in long purposeful strokes. His aching balls swung back and forth as his tempo steadily built up. Soon, loud squelching sounds could be heard as the pair’s sexual juices were compressed inside Megan’s stuffed orifice. This caused a steady stream of fluids to ooze out around the base of Abby’s cock and down Megan’s hind legs.
As the pair started to get the hang of things, Alan kept watching in sadness. He couldn’t tear his eyes away from Megan as the stallion fucked her into submission. The sight of Abby’s cock as it slid in and out rapidly, and the sounds of Megan’s shrill whinnies of delight, made Alan sick to the core. He prayed that this wasn’t the end of their relationship, although he was now having his doubts as he watched Megan enjoying every second as she was roughly fucked like a common beast.
This passionate lovemaking only got more intense as both horses built towards the release that they desperately crazed. Megan began pushing her hips back, thus forcing Abby’s shaft into her deepest recesses. Meanwhile Abby bit his mate’s mane as his humping got increasingly rigorous.
The stables were filled with loud whinnies and grunts as the intensity of their mating reached a fever-pitch. Megan shut her eyes, knowing that they were close. She felt the cock shudder inside her before the inevitable happened.
Abby let out one last triumphant whinny as his testicles churned and his dick trembled. This heralded his sweet release as the first streams of cum exploded inside the mare beneath him. Megan shivered in pleasure as she felt her mate’s semen quickly filling her up as he dumped his large load into her. Soon the excess was leaking out between her stretched vaginal lips and was being added to the other juices coating her inner thighs.
In the meantime Alan’s anger had turned to sorrow as he watched Abby’s cum dribbling out of his girlfriend’s equine snatch. He couldn’t believe what had just happened. That should be him on top of her right now, not this impostor! He began questioning whether she was still the girl he fell in love with or whether she was just a dumb, shameless animal who would now open her legs for just about anyone.
While Alan thought about his relationship the action finally died down as the last dribbles of cum trickled into Megan. Now, with their mating complete, Abby carefully withdrew himself from his mate. The stallion's enormous cock slipped out with ease as he thudded to the ground with his front hooves.
Meanwhile Megan was still revelling in her post-orgasmic state. The fire in her loins had been extinguished by the torrent of sticky cum that had spewed into her womb. She reckoned she was almost certainly pregnant now.
Her mare mind told her that this was great news; however she started to turn her thoughts back to Alan. She looked over to him and was instantly struck with guilt when she saw the sadness in his eyes. She tried to trot over to him but he backed away from her, seemingly disgusted by the very sight of her. She started to feel shame at what she had done. She had betrayed him. She started to doubt whether he could ever forgive her.
As the couple experienced a strange cocktail of emotions, Abby couldn’t be happier with himself. He had successfully bred his second mare of the day and now he needed a well-earned rest in order to recharge.
Worryingly, the fact that Abby had given in to his new stallion urges for a second time dealt his surviving humanity a hard blow. The human voice in his head was now even weaker than before, and it would only get quieter the more he acted like a true stallion.
Therefore Abby offered no resistance as he was led away. He was taken to a fresh stall with the name ‘Able’ written on the door, and so his new name became official. However, Able was too tired to really care about his new name. Soon he was curled up on the hay as he recovered from his exciting day.
Meanwhile the head attendant watched the other horses with interest. He decided to…
