Palador looks up at Wicked Queen Beth pleadingly, hoping for mercy, but Beth simply laughs, even more so as his eyes turn brown and expanding, filling his eye sockets as they turn into the deep eyes of a horse.
His skin appears to grow a rash, redness spreading all over, soon a deep crimson fur erupts from his skin and turns into a fine coat, his body barreling outwards and upwards as his body gains mass, he groans in denial as he loses the ability to move his fingers, seeing them begin to darken to a deep black.
His clothes tear as his body swells even more, his backbone making a creaking cracking noise as it shifts, his legs reversing into hind legs as he falls to his hands and feet, or rather his new hooves, his teeth grinding and changing into the flat herbivore teeth of a horse, his long tongue licking his larger lips as his horse head begins to complete, topping off with his pointed ears and a long black mane. Glancing back curiously, he sees his long tail swishing back and forth, connected to his mind.
Suddenly, as he breathes in another whiff of Galla's scent, he feels something else connected to his mind. His extremely long cock is fully erect, and his denial seems to be shrinking to a whisper. He staggers for a moment as he cannot trot on four feet just yet, his cock swaying left and right as he regains his stance, his eyes focusing on the mare before him.
He thinks No... this can't be right. As he pauses, his family cries out from the side, yelling "Resist her Palador! You are our son, you can beat her curse!"
Who said that? He looks to the voices, but another deep sniff of the smell makes him toss his head as precum begins to ooze from his cock in arousal, his mother moaning in fright as she sees what is about to unfurl. Moving forward, the stallion leans forward to Galla's sex, sniffing her for a moment. Galla, so busy trying not to lose her own sanity, is suddenly shocked by the touch, but oddly doesn't move away, she flicks her tail to the side to give him unhindered access. Palador's tongue gives her large slit a lick, she lets out a whinnying sigh of pleasure, bowing her head in submission.
Palador's primal urges see this, and he takes his chance. Moving forward, he leaps onto his hind legs, Queen Beth tries to look away but the guards force her to watch as the Stallion moves forward, his body pressing down on Galla's back as he probes her underbelly, finding her sex with his, he drives his cock into her.
Galla's senses explode in delight as she feels this massive rod filling her, her nostrils flaring as her legs spread to stable them both for what is to come, or cum rather, as they begin to have hot sex, Palador's shaft pumping deep into her. Galla's folds cling tight to him, taking all of his body in as his huge testicles ram into her ass, panting heavily as he fucks his once sister now his own queen. Galla doesn't deny him at all now, her body obviously showing the delights, her bestial spirit all but killed her human side.
The pressure builds in them both, Palador lets out a whinny of ecstacy as finally, his cum erupts, shooting load after load into her, his seed driving deep within her, his thrusts slowing down and down...
The Wicked Queen Beth cackles. "I can't wait to ride their children, I am sure they will be the fastest steeds in the land. Now then... what shall we do with the next one?"
