Heavy, the air was heavy with the scent of sex. Underneath Dakota, James bathed in a sticky miasma of pungent sex smells. He could smell the earthy scent of Dakota's wonderful cock, and the musty, smell of his own new horse genitals. The lack of a breeze or any air circulation in the clearing made the whole thing feel like a sweaty sauna of equine sex.
Rivulets of sweat were rolling off James's head, neck and back; running into his eyes, stinging; running down his chest and breasts, flicking off his taut nipples with each jiggle; streaming past his puffy asshole to mix with the squelching mix of fluids in his altered cleft. He looked down to marvel his beautiful swinging breasts, and behind it his horse cock, out of it's sheath but limp and dragging on the ground with each thrust. He had told himself, that this test was for his new parts only, and his body seemed to behave. Though he felt some pleasure in his cock too, even now, his want to make this a female centric experience was keeping him flaccid and floppy.
"F-ffuck me Dakota! Make my pussy stay!" James warbled, glad that he didn't have to do anything other than hold himself on hands and knees. Any more and he would have buckled long ago. Each long thrust he could feel penetrating deep, deep inside him, with Dakota's heavy dick running its length along his new massive equine clitoris.
They had been at it several minutes now, at one point James even thought he heard a bleating shout off in the forset, but paid it no heed. There were likely many animals in this place. But there was only one he cared about. Again and again Dakota thrust, each thrust accompanied by a grunt of a bray, with the pace increasing.
James knew that Dakota would finish soon and began to will his orgasm on faster, sooner. He began thinking the sexiest things he could think of, letting his imagination run wild.
Dakota's cock was the very first thing that popped into his head. Long. Mottled. Heavenly. He imagined being filled by cum. Filled so much his belly bulged. Holding it in. Letting it settle, warm and fertile. Letting it take. Belly pregnant with Dakota's offspring. That could happen. It really could... He could let it happen. The curse would work that way. It almost definitely would happen.
The realisation that all this wasn't just a wild sexy fantasy, but something that could genuinely happen was enough. James's first horse pussy orgasm radiated through his mind and body like a supernova. Deep in his core he felt the bubbling joy and release at what he was feeling. His pussy would forever be that of a mare. Dakota's mare. Feebly he could his cock, lazily dribbling thick cum in sympathy from an almost completely flaccid cock.
His breath caught as he continued to ride the orgasm, senses on fire as Dakota reached his zenith. The donkey snorted and James let out a happy, "Yeeeesssssss" as he felt warmth blossom deep inside him, radiating through his core. He pushed back, making sure Dakota was bottoming out in him, enterance at his new womb. Twitch after twich, each one feeling the heat blossom more and more. James's eyes fluttered closed, content. He drifted for a moment, happy, complete, tired, exhausted. He almost drifted off until he felt Dakota began to shift, pulling back. With a sad sigh James felt the cock pull from inside him with a wet *slurp*. He immediately felt the warm roll of cum dribbling from his equine pussy.
Instinct made him turn then, onto his back and hoist his legs up, cradling them to his knees. It felt right. He held the position for some time. Watching as Dakota licked his cock clean, meticulously; causing James to do the same. The donkey then went to a brook in the clearing, dringing deeply of what looked like ice cold crystal clear water. Then paced for a while, before laying down in some long grass to sleep.
Thirst eventually caused James to unhook his arms from his knees and stand up. He felt regret as chunky cum began sliding down his legs from an overfilled vagina. He hoped that he had held it enough to matter.
Knowing that it was time to make his way home, to sleep, he first drank deeply of the water, then used it to wash the worst of the cum, juice and sweat from his body, cold water invigourating him.
He noted as his hands roamed all over himself, how much softer his skin felt. Then it hit him. He'd lost his body hair. his legs, arms, chest, were all completely hairless. The only remaining hairy parst were his underarms and in a nest of black curls around his genitals, black hair matching black leathery skin. He noted too how much shapelier his legs looked, and that his thighs were thicker. Hands running around in marvel he felt... beautiful.
Time to go home. For now.
