While Jack grazed, Allison came up behind him. Jack gasped as he suddenly felt Allison's nose sniffing his new donkey cock.
Jack was stunned at the animal's amorous actions. Allison was now in a state of estrus, or heat.
His cock lengthened strained and he looked into Allison's eager eyes, and found a sensual beauty in her new form that he hadn't considered before. It wasn't right, or at least it wasn't supposed to be, he knew: Human's did not have sex with animals. But her longing gaze, his loneliness and his strange bestial attraction for her were providing a cock tail that was hard, if not impossible, to resist.
Allison began to lick his cock, moving the donkey tongue rapidly all up and down the shaft of his penis and over the head, enthusiastically lapping at his manhood. At first, Jack was fearful that she might bite him with her big, bucked teeth, but she was gentle and careful with him, stimulating him only with her wet tongue that moved across his cock and gently over his balls.
"HEEEEEEE-HAAAAAWWW!!! HEEEEEEEE-HAAAAAAAWWW!!!" Jack brayed as she licked at him.
In the back of his mind there was voice screaming 'what the hell are you doing?' but he was too drunk and far too turned on to listen to it.
Jack was sure he was about to cum all over Allison's muzzle when abruptly she stopped. Then Allison trotted about two feet and then stood with her rump aimed at him, her hind legs spread apart and her butt thrust up in the air invitingly.
Allison lifted her tail up and out of the way, giving him a pornographic view of both her holes and she looked back at him over her shoulder with an unmistakable expression that said 'Come take me, stud.'
Allison was as shameless and sexual as any other beast in the wild.
Jack approached her and buried his tongue in her donkey pussy. He had no idea what the structure was like, and wasn't even sure if he could find the clitoris, but he soon did.
Allison brayed in pleasure, moving her long ears, breathing deepened and wagging her tail back and forth excitedly. Jack lapped at her hungrily, sucking the lips and tissues into his mouth and achieving the desired effect as Allison gave whining sounds of pleasure. Nothing about this tasted disgusting.
He sucked on her donkey clit, ignoring Allison's wagging tail as it inadvertently smacked him on the top of the head, plunging his tongue deep into her pussy. The female donkey whined and brayed, her body shaking with delight.
Eventually, Jack stopped and he stood behind her resting his front hooves on her back . Allison looked at him again with those lusty, expectant amber eyes, her tongue hanging out of her mouth as she panted excitedly. He rubbed his hard and long penis teasingly across her black vagina, making her whimper with lust. Her donkey juices coated his dick as he caressed her vulva with it.
Jack entered her, pushing his penis past the lips and into the canal of her donkey vulva. He had no problem entering her. He began to move in and out, thrusting his hips into her wet donkey's vagina. He moaned as he fucked her.
He picked up speed, her body so incredible against his. He could feel her soft fur of her butt caressing him with her tail smacking his stomach.
"HAAAAAW! HAAAAAW! HAAAAAW! HAAAAAW-HEEEE! HAAAAAW-HEEEEEEEEEEEE!", Allison brayed excited.
Jack wondered if she could understand anything that he was saying. She seemed to respond to his words; was it possible that the Allison he'd known and loved was still somewhere in this horny beast? He couldn't stop to think about that, he was too horny and she felt just so damn good.
Allison's eyes rolled back as her whole body trembled and shuddered. She threw her head back and let out a long bray of delight as her furry body convulsed. Jack couldn't believe his eyes: He had thought that female donkeys were not capable of reaching orgasm, but that was clearly what had just happened here. Maybe it was something peculiar to transformed humans? He didn't know, but Allison seemed to be writhing in pleasure.
As Jack pulled out of her, breathing hard, Allison came up and licked his face affectionately. He was spent, and exhausted, but they were both strangely exhilarated.
