Fuck, he couldn’t resist this. It felt too good. He wanted to take them both further into these surreal changes.
The mare’s eyes widened and she visibly smiled, her front teeth showing, as Jason tried to position himself behind her. She nodded her approval, shifting on her hooves and lowering her back legs to help him reach her pussy. Her breathing quickened, he could hear her panting. Great chuffs from her powerful lungs.
Apparently the promise of more transformation was as exciting for the horse as it was for Jason.
He positioned his eight inch horse cock and gripped it as he guided it towards the mark. The mare watched the moment with a lick of her lips, stepping on her hooves awkwardly to adjust the way she was standing for him to enter her.
Jason’s cock slid in a very wet and waiting hole. The mare dropped her head down and closed her eyes. Her thick anus twitched beneath her tail and she winked her pussy, gripping Jason inside of her folds.
“F-Fuck, girl! Easy!” Jason gasped at the tight muscle control the mare had, apparently enhanced now that she could control it. For a moment he was forced to move with her as she shifted, which tugged a little uncomfortably. “Y-You’re big and strong and I’m little, okay?”
The mare turned her head and nodded. Somehow that turned her on even more, but she seemed to understand what he was getting at. Gently. Gently. Careful.
Jason gripped the horse’s thighs, fingers tangling in her coarse fur, and he began to thrust. He closed his eyes and felt. Her quick breathing. The shifts of her thick powerful muscles as she adjusted her position to accommodate her much shorter human partner. His bigger size was less hot dog down a hallway but there was no way his still human scaled prick was going to satisfy this mare. He pumped into her. And to his astonishment and delight, she gently pushed back. It took a little bit of getting used to, because she was a very powerful creature, but in time they found a rhythm that worked. She had to be so much more gentle.
It didn’t take long. Jason began to blush and sweat as his junior sized horse prick slid back and forth in the mare’s passage. She was angling down in such a way to increase his stimulation, and those little clenchy winks of hers were definitely enjoyable. With a few violent thrusts, which the horse seemed to like best, Jason unloaded, another gush of cum washing through her tunnel. She clenched him several times, making him moan, draining him of every drop.
They pulled away, Jason’s floppy horse dick slowly shrinking back to its sheath. The mare was breathy, still excited, and turned to watch the human. They stood together for a good long while before suddenly the horse seemed to tremble.
She put her head down, ears back, and let out a whinny of delight that seemed to grow strange and distorted as it left her lips. At the same time, Jason suddenly felt the tingle again, and stared down at his sheath with wide eyes, watching it start to darken from human pink to deep jet black, the flesh of his sheath thickening and deepening, offering him better protection. He couldn’t get a gauge of how big his dick itself was now, but it was sure to be larger.
The mare, though, was going through something profound. She gagged suddenly, gasping, and let out a strange gurgling noise. Worried, Jason went to comfort her, but whatever was happening had already ended.
The horse closed her eyes, gasping, shaking a little, and seemed to concentrate deeply. She was in extreme focus. Jason watched in curiosity, jumping as the mare opened her eyes and stared at him suddenly, raising to her full height.
She opened her mouth and let out a squeak of sorts. Annoyed, she shook her head, brow furrowed, and tried again. She was attempting to project. To...
“You’re trying to talk!” Jason gasped, astonished. “Aren’t you?”
The mare nodded excitedly and bounced on her hooves, kind of like a big puppy. She settled, tried to hum, and her eyes widened as she produced a very non-horse noise. She nodded, trying to work through whatever she was doing, and hummed again. And again. Each time she started to make new noises. New sounds. Her heart was racing in excitement by the time she produced on “urgh” and then a “ohhh” and finally an “ahhhh.”
Jason stared in shock, hands on his mouth. They were both shaking in that moment.
“N-Nooot... quit,” the horse whispered, her ‘voice’ hoarse and jagged. With a strange wet gurgling quality to it. She gulped in air suddenly and let out a rough cough, shaking her head in annoyance.
“Needh... morrrre... youuuuu,” she said feebly, forcing it out, her new voice clearly struggling.
Jason nodded, eyes wide, and glanced down at his strangely more alluring sheath. The mare stared at it too and nodded her approval.
“Ka—kayoot,” she coughed.
“Cute?” Jason giggled, looking back to the nodding horse with a blush. “Uh, well, I’m a little tired to go again so quickly. D-Do you want to help me get it up?”
