There were Tony and Roger, loaded into a pony show trailer in back of a shiny brown pick-up with a Tony Farms logo, Tony was jazzed to see the logo featured his silhouette, complete with appropriate errection. The front and sides of the trailer had large glass panels to allow the public to admire the show animals within.
The sun shining on the trailer warmed things up considerably to the point where the ponies were warm, despite the back of the trailer being open. As a result the pheromones' inside the confined trailer were intense. Both ponies sprouted rock hard errections. Their arms were strapped at their sides in typical pony fashion, and they were both further strapped into the trailer to keep them standing tall no matter what the driver did. At this point neither was sporting ball weights as their lemon sized balls were considered fully developed.
Tony was sweating slightly, his cock bouncing up and down with the road, and he was grinning from horse ear to ear. He was as horny as he had ever been in his life. He divided his time between showing off for random drivers and passengers who passed them on the road and shouting obscene suggestions to Roger over the road noise. Tony would paw the ground and toss his mane, especially for the kids.
Roger for his part was a big black stud, and thanks to the breeder training he knew it. He stood tall and impressive flexing his muscles as the light sweat ran over his body. He wanted that filly ass of Tony's so bad. He wanted to breed it like it had never been bred before. That chestnut ass, that beautiful mane and tail. No doubt Roger was lucky. Tony was quite the sexy filly. Oh that thoroughbred ass...
As the truck finally tuned in the driveway, Tony yelled, "We're home stud. The foreplay is almost over."
"Good, I want to plow your ass like a new field. I'm gonna hilt you filly." Roger responded in his deeper gravely voice. "I wanna fuck your ass for real."
"I want that cock of yours buried in my ass. I want your balls slapping mine under my tail. Then, I want a sample of what's under your tail." Tony grinned suggestively at Roger.
Roger laughed heartily, "If you want that filly, ya gotta earn it. You're gonna have to make me give it to you." Now Roger was grinning lewdly and sticking his tongue out suggestively.
The pick-up pulled up outside the barn, where a small gathering of people was waiting. Max pulled up and parked in front of the truck. Max got out and greeted the assembled group. All of these folks were new hires since Tony and Roger were sent to the hospital.
At that point a woman stepped forward and took command of the situation. "Alright folks, it's showtime. We are going to take the ponies out one at a time, the racer first. I want one on the lead, and another controlling the arms. Remember both of these boys are sex crazed and are liable to breed you as well as each other. We are taking them both back to breeding stall 1. Got it?" There were no questions for Liz Delacruz, Max's new trainer.
"I'll take the lead ma'am," Bob Lindorf, the new barn manager stepped forward and unlocked Tony's side of the trailer. Tony turned his head to get a look. A big beefy smiling white am with a heavy Kentucky accent leaned in and started stroking Tony's mane and flanks. "That's a good boy. We're gonna get you out of here into a breeding stall. Be calm a few minutes for me ok?" Tony whickered before he realized what he was doing. He nuzzled the nice man gently with his head and nodded. It was strange. Tony felt calm and re-assured as the nice man led him into the barn and the breeder stall. The hand controlling his arms had no issues. "My name's Bob, you and I will get to know each other better when you can think straight. Now I gotta get your friend." One final stroke of the mane and Bob headed back for the black breeder.
A few minutes later Bob and the ranch hand returned with Roger. "Easy big fella, you'll get your rocks off in a minute." Roger whinnied and pulled on the leads. His eyes rolled back. The hand on his arms started to react. "It's the racer's pheromones'. Easy on the arms. Calm down stud, calm down boy." Slowly Roger did regain control, even as Tony was fighting his own urge to freak. Fortunately Bob was able to get Roger in the stall and the door secured.
Trainer Liz looking on issued further orders, "Good job people, leave the arm restraints on for now, it's too dangerous to take them off. Thanks all for now." Then to the ponies, "Have fun boys bonding and breeding." With that she waived and everyone but Max left the barn.
Roger was already hilt deep in Tony who was screaming happily from being impaled. He had a savage grin on his face as he thrust back almost as hard as the breeder thrust forward. It quickly turned into pure animal sex as both beasts huffed and thrust against each other. There were no words, none were required, and both ponies were incapable of speaking. The world was rut, and it was mind-blowing.
Max stood and watched awhile as his best friend fucked his brother, both as quite handsome beasts. Max began to understand the appeal for Tony: awesome sex, no responsibilities, being naked 24/7, flaunting it, and getting back to his track star dream of winning races. Tony shook his head. He found his pleasures in other ways. He left his friend and brother to their mating.
