Carter was wide-eyed in shock as the bull’s tongue continued to sample her unfamiliar vagina. She couldn’t hold back a low moo as the pressure on her sensitive folds sent ripples throughout her new body. The worst thing by far though was the shameful feeling of lust that was beginning to rise to the surface.
“That a girl” Jenkins said in a mocking tone. “I knew you’d love being a horny cow, in fact I bet that’s what you’ve always wanted deep down.”
Carter glared at Jenkins angrily, her eyes seething with hatred for the man that had doomed her.
Regrettably, the cow’s efforts to seem intimidating quickly began to falter as her lustful bellows steadily became louder, needier and more frequent. In fact, she seemed to lose her composure completely when the bull started to penetrate her. The way the slippery tongue stretched her tight lips open and occasionally tickled her clit sent shivers down her spine. It soon became obvious just how much Carter was enjoying herself as the licking started to produce sticky wet sounds as her pussy grew slick; clearly a positive reaction to the intimate foreplay.
“There we are,” Jenkins continued to tease, “I bet that feels wonderful. However, I think I know what you really want. Why wait any longer?”
Carter was only vaguely aware of Jenkins’ words, given that she was far too preoccupied with the pleasurable heat radiating from inside her eager cunt. However, the urge that the doctor described was indeed building within her. The bull’s tongue had driven her to new heights of pleasure, but it wasn’t enough to satisfy her primal urges, nor to rid her of the infernal heat in her loins.
After a short while it became apparent that Carter couldn’t take any more. With a loud needy bellow she pushed off the stall door and landed on her four hooves for the first time. The sudden movement made the tongue slip out of her, but Carter wasn’t too concerned by this. Instead, she moved alongside the bull, studying him in a distinctly inhuman way.
The cow cast her eyes over the bull’s powerful form. He was large and muscled, with a dominant air of authority; physically represented by a pair of impressive horns. However, Carter was particularly excited when she looked beneath the impressive animal. The bull sported a pair of large, full testicles which hung low in a dark sack between his hind legs. Then the cow paused when she spotted the bull’s fully-erect penis bobbing below him. The organ was long, thick and throbbing as it leaked pre-cum onto the stall floor.
Of course, what remained of Carter’s human mind was utterly horrified by her body’s actions. She knew that if she was impregnated there was no going back. She had to resist!
Regrettably, these feint protests were nothing compared to the overpowering female hormones surging through her brain, ordering her to mate as soon as possible. And so, to her horror, Carter couldn’t stop herself from turning around, raising her ropey tail and flashing her hot slick vagina to the eager bull.
Dr Jenkins laughed upon seeing this. “Brilliant! Now you shall get what you deserve for being such a good cow.”
Carter had now completely blocked out the doctor’s words. Instead she was solely focussed on the bull behind her. She let out a low seductive mating call as she readied herself for being mounted. The pesky human protests were still a nagging presence in her mind, but they were growing quieter by the second.
Mercifully, at least for the cow side of Carter’s personality, the bull decided that it was time to fulfill his own urges. With a grunt he unceremoniously reared-up and landed roughly on the cow’s back with a heavy thud.
Passion was clearly overwhelming the bull as he began working his hips rapidly; frantically jabbing with his enormous cock as he sought out Carter’s warm inviting entrance. The cow mooed out in frustration as she felt the cock prodding between her legs, sometimes barely missing the mark. The anticipation of having the heavenly organ slipping inside her eager pussy was nearly killing her.
The bull continued for a dozen-or-so more jabs before, mercifully, he struck gold.
Carter cried out as the tip of the cock parted her virgin pussy lips, spreading them into a tight ‘O’ shape as her folds wrapped around his member. Now that he was in position the bull eased himself forward, allowing him to force more of his length inside the warm inviting passage.
The bull continued to shove inch after inch inside, making the cow bellow out beneath him. Then, once his cock was almost fully-enveloped inside his mate, he began to thrust.
Jenkins watched in fascination as the bull began forcefully pounding Carter’s already-strained vagina. The former-man seemed to have lost any hint of shame by now as she threw her head back and bellowed loudly whenever her mate rammed into her. Seeing this display made the doctor feel mixed emotions. On the one hand this bastard was getting what he deserved, but on the other, this could have been him right now. Getting revenge had been fun, but he was still in grave danger of meeting a similar fate. He began formulating a plan for how to escape, although he decided he had to make sure that Carter’s fate was sealed first. Now he waited patiently as the mating gathered tempo.
After a minute-or-so, both animals had settled into a steady rhythm. The bull was now rutting passionately as he stuffed his dick inside his mate in quick hard thrusts. In reply, Carter did her best to rock in time with his movements, letting him press his dick right up against her cervix. Beneath the couple, Carter’s enormous udder swung heavily beneath her like a pendulum, colliding occasionally with her mate’s ball sack as he fucked her relentlessly.
As Carter stood beneath her mate, an odd tranquility settled over her. The human voice telling her to stop was only audible for brief flashes, and even if she wanted to there was no way she could shift the enormous bull now. The only real option left was to enjoy herself, and accept that there was nothing she could do to stop the inevitable.
Having now accepted her fate, Carter could fully revel in the pleasure of that moment. The way her vagina hugged the advancing shaft as it rubbed her sensitive clit and inner walls sent electric jolts of delight coursing through her, making her quiver in delight. Plus, feeling his pre-cum and her vaginal juices squelching together and running down her thighs in a warm, sticky cocktail was also oddly captivating. She unleashed more lustful bellows, not holding back at all as her first bovine climax began to crest.
As Carter begged for her sweet release, her mate’s thrusts grew in urgency as he too sought to finish what he started. The bull delivered a few short hard thrusts before shoving his dick as far into Carter’s eager hole as he could. The cow trembled and let out one last bellow of ecstasy as she orgasmed hard, just as the bull’s cock shuddered inside her.
Feminine juices sprayed out around the base of the bull’s cock and coated its entire length as Carter climaxed dramatically. In response, the bull tensed up before releasing his own prize. Carter shut her eyes and revelled in the moment as the first hot jets of cum splattered inside her passage. Feeling the warm gooey liquid flowing into her fertile body made her feel deeply satisfied on a primal level. Her virile mate had almost certainly made her pregnant, meaning she could fulfill her natural duty to reproduce.
As more bull semen was ejaculated inside her, Carter’s gaping vagina was soon overwhelmed. A torrent of cum flooded out between her stretched pussy lips, quickly joining various other fluids as they ran down her hind legs and udder.
Meanwhile, Dr Jenkins watched from the sidelines as the bull emptied his giant balls into his mate. Now satisfied that the farm manager was locked into this form forever, Jenkins slipped away to begin formulating an escape plan.
Carter watched Jenkins walk away, only faintly concerned about who the mysterious man was. Instead she remained focussed on her mate, standing submissively as the last watery drops of semen dribbled inside her. The bull rested on top of her for a moment, doing his best to ensure that his sperm entered her womb and found her unfertilised eggs.
Finally, after a minute spent resting on Carter’s back, the bull slowly extracted himself from her slick passage. His dick exited with a wet *pop* as sexual juices spilled out in its wake. Then his hooves landed with a heavy thud, allowing him to get a close-up view as he inspected his handiwork.
However, he didn’t have to look hard to see that Carter had been utterly despoiled.
Everything between the cow’s legs was streaked with cum and vaginal juices. Her pussy remained gaping open slightly, allowing the bull to see the sheer quantity of cum inside her as the excess spilled out of the abused orifice. Small streams of various fluids ran down her hind legs and udder, sometimes mixing together into disgusting globs that congealed and clung to her hairy body.
After studying his latest conquest, the bull was satisfied that she was now carrying his calf. However, there was no harm in making sure...
Carter had barely had five minutes to recover when she noticed that the bull was starting to get excited again. She was tired and hungry, while the need to mate seemed to have been quenched by her mate’s hot sticky cum.
And yet the bull had shown her a fun time and made her into a hopeful mother; surely the least she could do was repay him for his love and affection?
With that, Carter let out a suggestive moo as she presented her rear-end to her mate. The bull showed no hesitation in returning to his position on top of the eager female. Soon the barn was filled with more loud moos and bellows as the two lovers got back into the swing of things.
Meanwhile, Dr Jenkins crept deeper into the farm building, trying to think of a way to escape the Zoo...
