By this point, there wasn't much human left in Frank. Maybe he had a bit more of a glimmer of intelligence in his eyes than the average ass, and while the rest of his clothes had been removed by his concerned wife or frantic kicks as they were torn to shreds, he still somehow had a power tie hanging from his neck. The main thing that was left of the old Frank however was a general sense of greed and entitlement.
He glanced around the pen they'd stuck him in. It did have a hell of a lot more fresh grass handy than his home and office combined, and he appreciated that. Plus there was a nice trough of water, easier to get at than a water cooler, but he was alone here. It was just him, George and Alice Smith coming to check on him now and then, and every couple days his wife would stop by. They'd met the Smith's at a conference a few years back. Used to be big power players, before George got this stupid idea in his head to retire and "live the simple life." He rolled his eyes at the thought of it.
That wasn't his plan. The day he retired, he was going to start living it up. Ditch that nagging wife with her narrow little butt and complete lack of a tail, find a few nice barely legal jennies that worshipped the ground he walked on, and just live it up like some sexy proper stud. Hell if he knew how to get hooked up like that though. Before his hooves properly thickened up and there were all those other ones on the side, he'd tried looking up sexy donkies and nothing came up but a bunch of dudes with scrawny little hairless human women. Disgusting. And now he was stuck here, hung like a damn horse, but he couldn't even grab the thing and get some release.
Frank just paced about, until he saw Alice entering the paddock to pump some water into the trough. It was a sick though, he knew, but seeing her bending over like that still kinda did it for him. After struggling with the idea a few moments longer, he just shook his head, hopped up to mount her, and started licking the back of her neck. Wasn't getting anywhere at first since she had those pants covering up the sweet spot, but suddenly the luckiest thing happened. Alice started transforming into a fine little jenny! It happened a hell of a lot faster than Frank's own change at that. Ripped right out of those pants, fur spreading from her neck across her whole body. By the time he was really up there properly riding her, she was just braying with glee as all the years melted off her. This was exactly what he needed.
Just as he was finished and Alice was quivering on her new hooves, no doubt losing her mind from how great he was, when suddenly George came running up, screaming at him. Frank really was just plain sick of him, and gave him a good swift kick in the gut the left him doubled over. And of course, seeing him laid out with his ass in the air, Frank had a thought. If it'd worked on that other gross scrawny human...
Sure enough, when he swung around, mounted George, and gave his neck a little lick, he too came bursting out of his overalls, transforming into the sexiest little jenny around, and giving him someone else to really give it too. He took turns between the two a few times before really wearing himself out. Of course, someone as important as him needed more of a herd than just these two to keep him satisfied. Maybe that wife wasn't as old and worthless as he thought.
