Mika stretched, his cock too hard to be comfortable. Knowing it would be hours before he could breed, Mika turned to the hole in his stall that contained the animal named Toy, A animal used only for breeding bulls when heifers were unavailable.
A scream of pain followed Mika mounting the male on the other side of the wall unable to resist. The sound drove Mika faster, loving the screams of the animal who tried to deny him.
When Mika was finished, sobs echoed on the other side as Toy tried to recover from the assault but the bull cared not. The bull went to his trough and saw there was paste smelling of orange as it normally did. Off to the side there was the smallest glob of paste that Mika sniffed and got the hint of strawberry. With a shrug, the bull finished off both pastes and waited for his handler.
****************************
Po was lead out of her stall and to what she recognized as a shower section. It was different than ponies, being on four legs rather than two. The water wasn't as warm as the stable, but Po didn't find it uncomfortably cold.
"You will be bred today." John explained. "Mika is here and recovered, and you have had a little practice with Tomo. However, I will warn you, Mika is very different than Tomo, as you will find out. No one will stop Mika unless he is going to seriously harm you, he's the bull and you are part of his herd. I will tell you right now, the rest of the herd likes him better than you...almost better than each other. "
Po didn't comment as John washed her, but not like her trainer had as a pony, there was no caressing, no releases in the wash.
Disgruntled, Po was lead back to her stall where she saw some strawberry paste waiting for her. Knowing how it would make her feel, she gobbled it down.
*****************************************
Two hours later Mika was screaming in his stall, demanding to be released to breed. While used to his normal cock, the throbbing need was making him furious to mount a heifer.
Elise came in answer her bull's demand. She smiled as she saw him, cock stiffer than usual. Mika glared at his handler as she led him toward the field.
"Aww, stop it Mika. Your pouting is stupid." Elise chastised him, who huffed a still furious huff. The handler pulled up short, looking her bull in the eyes. "Listen, Mika. Here's what happening. The heifer you are breeding is new, you've seen her. What you don't know is that she used to be the pony who delivered the food here. She failed at being a pony. Now she is a heifer, and she still thinks she's better than the other heifers."
Mika growled, fury growing toward the heifer who thought she was better than HIS heifer, Tori.
"That's the point. She had the same paste you did. Increase your desire, and hers too. Your collar will be on, hers will not. We want you to break her, humiliate her. Show her what her new place is. She is the lowest heifer we have, and she needs to know it. Do you understand, Mika?"
Hearing his task, Mika stomped his hoof, looking forward to breaking this new heifer. When he made it to the field, he was alone. Released into the space, Mika took a long moment to relieve his bladder and returned to his handler. His cock was desperate, even the cool wind aroused him. He wanted a heifer, and he wanted it now.
********************************
John led his heifer to the edge of the field. He could see Mika at the entrance of the bull barn, and read the look in his eye. The handler of the heifer knew what was coming, a brutal breeding to reinforce the station his heifer now had. She had to be taught, and lessons are abundantly clear at the end of a bull's cock.
His heifer looked at him, her cunt on fire and ready to be released into the field to meet her new bull. She had seen Tori and the bull interact and knew she could do better...at least her cunt said she could. Her confidence would carry her.
She moved into the field after being released and looked back at her smiling handler. He was cheering her on. She let out a plain moo, letting the bull know she was here. She could see him staring at her, his cock jutting out from under him. Seeing it sent shivers through her.
A loud click met Po's ears as Mika was released into the field to meet her. Po moved as she had seen Violet move, seductive to entice the bull.
