Jenny watched in despair as her lovely wife began to change. Rusty-brown fur had already started to spread from where she was injected on her arm, while her ears had grown slightly more pointed.
In response, Abby ran at the door, trying desperately to unlock the heavy bolt as she screamed for help. However, nobody came to her rescue. The attendants held the door securely shut as they leaned against it whilst their captive beat against it madly.
Sadly, Abby’s anger and frustration seemed to encourage more changes. Her muscles began to surge with more strength as they became more elastic and powerful. Her upper arms and legs lengthened as they grew stronger, causing the attendants to give ground as they fought to hold her back.
Abby used her longer arms to deliver a powerful punch to the assistant, sending him crashing to the floor. The other attendant dodged a few more blows, knowing that he only had to hold on for a little longer. After a few more of Abby’s wild swings, the man looked up to see if it was safe to let go. Smiling to himself, he left his position behind the stall door and stepped back to watch. He then lifted his arms whilst facing at Abby, as if challenging her to come and get him.
Now more enraged following this taunt, Abby reached for the bolt on the other side of the door. However, to her dismay, her body had changed significantly during her violent outburst. Her chest had begun to barrel outwards as her body packed on more and more weight. Her neck had also started to lengthen while a dark mane and tail had taken shape.
However, the most critical change was the development of her new hooves. Her hands and feet had completely lost their dexterity, having become solid keratin lumps designed simply to support a four-legged creature. She flailed uselessly at the bolt, no longer able to grip it without her fingers. The attendant laughed evilly as his captive became more and more desperate.
Jenny continued to watch in horror as the transformation continued to take hold. Soon there was a loud pop as Abby’s hips adjusted for four-legged travel. Now she had to lean against the stall door in order to stay upright. Unfortunately, as bad as things already were for Abby, there was one development that was particularly devastating. As she continued to struggle, Abby’s frustration and anger seemed to manifest themselves physically.
Nobody seemed to notice this latest change, not least Abby who was still fumbling with the stall door. However, Jenny quite literally caught wind of her wife’s latest change when she detected an unfamiliar smell in the air. It smelt heavy and musky, similar to how a stallion might smell…
Jenny’s eyes then widened in shock at having discovered the extent of the attendant’s cruelty. She continued to stomp her hooves and whinny in anger. But her protests fell on deaf ears. The attendant simply looked on in amusement as the woman changed before him.
The smell got more and more intense as Abby’s changes advanced. Her lower body was hidden behind the stall door, but Jenny’s instincts told her that her wife was becoming a male animal.
Sadly, Jenny was not the only one who noticed this latest change. Abby’s eyes shot open when she felt an unknown sensation coming from her rear-end. She looked back to see Sophie’s head buried between her legs. Abby moaned as she felt the mare’s wet mouth and tongue sucking on some unknown part of her anatomy. It was only when she looked beneath herself that she finally realised what was going on. Now, dangling between her hind legs was a distinctly equine set of cock and balls. She should have been mortified, but instead she shuddered in pleasure as Sophie continued to suck away on her hairy, tennis ball-sized testicles.
This loving attention helped to push the changes towards their conclusion. Jenny watched as her wife’s breasts retreated, while her beautiful face extended into an equine muzzle. She also began to smell her wife’s arousal as her member continued to lengthen.
Eventually, Abby could take it no longer. She gave up trying to open the door with her useless hooves. Instead she pushed off from the door and landed on all fours. Now, instead of focusing on escaping, Abby seemed to be preoccupied with the mare in the stall with her.
She instinctively nickered for Sophie to present herself, and the mare happily obeyed. Jenny caught glimpses of the other mare’s arousal as she showed the stallion her wet folds. The human portion of Jenny’s mind felt sick to the core as she saw her wife eyeing-up the slutty mare. However, as Abby moved away from the door, Jenny was able to catch a glimpse of her wife’s new equipment for the first time. Bit by bit, feelings of anger turned to feelings of jealousy. Without even noticing, she gradually grew wet between her own legs as she imagined having her wife’s member inside her!
With the changes now completed, Abby was eagerly limbering up to take her, or rather his, first mare. With his cock now fully erect, the new stallion approached Sophie, ready to put his new equipment to good use.
