Everything went black for a very brief moment, then world instantly came into focus. His head was down, just as his jaw tore away another clump of grass. Jeff's very first clump of grass.
He raised his head, and the world around him was a very dull, washed out, "cold" looking green, blue, and grays. He automatically swallowed the slimy clump of green grass, and let out his very first bray:
"Hhhee Hhhaaww hhhee hhaaw hhheee hhaaww hhhee Hhhaaww!!"
"Oh shit.," He thought. He looked around on his much longer neck. Twisted it around to the left to look at himself. The huge gray bulky side of a fat donkey extending behind him came into view. He stood there in shock looking at it. Processing for the first time that the side of a fat gray donkey was now HIS side! A tail periodically flicking in and out of his view. He brayed at it. "Hee hhaaww" he said, meaning to say "it can't be!"
His huge black monster cock was already erect, and his horniness he had while at his desk suddenly slammed it his brain! But this time, it was even more intense! The cock started pumping on its own, slapping into his underside. Normally, he uses his left hand to jerk off. But he has no left hand now! Just a hoof on the end of a leg!
"Hhhee hhhhaaww HHHHEEE HHAAWW HHHEE HHHAAWWW!!! Jeff continued vocalizing uncontrollably. He was far beyond ready to cum! He's never felt this intense before! It was so much, that he closed his new body's large brown eyes as he imagined with perfect picture-wuality clarity of what he now looks like, and what he's stuck with for the rest of his life!
He kept trying to talk, but could only stand there braying with his eyes shut. His enormous black dick, stiff and long as a flagpole, was dancing up and down, slapping his underbelly. The felt the rush as every muscle in his body tightened up, and his brain showering fire works. He couldn't breath, except a slow exhale in small bursts "haw...haw...haw..." Finally, the cum reached his new cock's smelly equine-shaped flat top, and the seed his body can produce came rocketed out towards his from hooves, thick as icing, and off-white, almost yellowish. One pump. Two pumps. Three. Four. And five!
It began to settle back down, but still with the intense tingling throughout his hoselike private tube that would very slowly subside over the next hour or so.
With that over with, Jeff opened his eyes again and took a look around. This time, with his first mindful perceptiveness, discovering the true extent of his situation.
Standing on all fours? Check
Inability to stand on just two legs? Check
Washed out dull greens, blues, and grays for vision, and extreme binocular vision with a large blind spot directly in front of his face? Check, check, and check.
He then mentally tried opening his hands, but much to his growing horror and dread, he couldn't! They were trapped! Replaced by immobile hard hooves!
"Hee hhaaww hhhee Hhhaaww." Inability to speak: check!
Then with even greater dread at what he voluntarily did to himself, he realized this is now his permanant position in life on this planet! He well and truly has joined the life of a simple, mindless farm animal. Except, he wasn't mindless like all the others! And nobody would ever know that! They would just see a dumb old common gray-furred donkey when looking At him, then go about their merry way. Leaving him alone with his donkeydom!
"Hhee hhaaw," he said one more time when his belly began rumbling. Suddenly, his head was forced to lower, and jaw opened wide. His huge blocky teeth grabbed a clump of grass, and started chewing. This was completely involuntary! Then his dick came rolling back out of its sheath, and a long, noisy stream of piss came shooting out like a hose. Also uncontrolled. The piss wetting down part of his already dirty white belly fur, and puddling around both of his front hooves. He won't ever be using those to eat with anyway. Not ever.
Then his head took another dip, he smelled the donkey urine that technically wasn't his but now is, as well as the cum-covered grass. His tongue came out as his wife jaw opened again for more grass-fed sustenance. Jeff tried with all of his might to resist, "no, no, no! Not that! Stop! What are doing!?" Screamed his mind.
But it was useless. his teeth closed on a clump of piss and cum-covered grass. His large, slimy, unclean donkey tongue tasted it, and rolled it around in his mouth. Chewing it with his permanently unbrushed, plaque-covered, blocky yellow teeth with slimy remnants of grass that was already stuck in the teeth just before Jeff switched with this vile body. He'd be crying if he could. He'd be gagging if he could. But his body was accepting this dirty, disgusting behavior, even as his mind was railing against it.
He started automatically taking small steps forward, and constantly lowering his head for more and more mouthfuls of grass. Each bite as nasty and as humiliating as the last. He would periodically involuntarily fertilize the endless field he was in as his body continued to forcefully nourish itself against his will.
He had no idea how long this went on. Too long, he thought. When finally, mercifully, he was given back control of his body. It would take him several long moments to realize this, as he stood stupidly looking out of his large dark eyes like a dumb donkey would do.
He heard a noise, and one of his long, broad furry ears twitched in that direction. He looked to his right, and his eyesight wandered towards the side and posterior end of his new body that sticks far out behind his head. And felt another clump leave his new black puckered anus.
"Hee haaww" he sadly said, trying once more to speak. He stood there, looking over his new body he's now stuck with! His hooves ending on four legs. His gray fur. Fat sides. He got a good look of the shape of his shadow. Ears pointing far out from his head on the ground.
He wasn't just a donkey though. He was actually a natural-born donkey with a history of really bad habits. Habits he will now be forced to take over from the real donkey that was born with this body from now on, and completely unable to control them. All because he wanted one single moment like this, with the idea of being stuck like this.
