A groan announced to the camera that the bull was awake again. His head was pounding and his body felt heavy. No, not his body; part of his body. He slowly got back on all fours and felt something swing underneath him.
The next sound was a gasp as he saw the cock now attached to his body. Currently flaccid it is four times as thick as his previous one had been erect. Thinking about his cock was causing it to harden and he marveled at the size it expanded to. The bull wasn't wielding a cock, it was nearly as thick around as a baseball bat and nearly touched the ground as it swung erect before him; close to thirteen inches.
Looking around his room he saw the hole in the wall still remained, and now the bull understood why the opening was so large. Knowing what was in store for him, he wasted no time thrusting his cock into the hole, which now, it barely fit.
As he fucked the wall he let out a constant stream of moans. Everything was intensified from his old cock. The closer he came to release the moans became shouts until he screamed and passed out.
He wasn't out very long and his cock was still hard. Following his, now bull, instincts he went back to fucking the wall. While the sensations were the same, they weren't as overwhelming as he was expecting it somewhat.
It took four fuck sessions, with less than five minutes between them, for the bull to wear himself out. When he did he shuffled over to his food and water trough, gulping down as much as he could hold of both.

Richie's next report was taking time. He would type something, then delete it and try again. It wasn't that he didn't have anything to report, he was just finding it hard to report about it.
The male had progressed as expected. He was now dominated by his cock, using the wall as often as he could, up to four times a day. Since his transformation he had been given a marker in his ear, a piercing he barely noticed while in the middle of a fuck. He was now B-4, the fourth bull out of the facility. That was now how the handlers would refer to him, knowing the farm he was transferred to would change the name. Unlike animals, with the right incentive the human variety could relearn a name. It was about time for his final test, the live test as it were. He was going to fuck the heifer again, this time as a bull. If he passed that, he would be either sold or transferred to a farm where he would live out his days.

B-4, the bull, had paced his small two room area for over an hour. Early that morning a handler had come in and locked up his cock into a large cage, not letting him get the release he had become accustomed to. About five hours later his cock was beginning to throb. He stomped his hooves and let out a disgruntled sound.
Moments later the same handler came into the room with a lead. "Bull, this is your final test before you move to a farm." Walking forward the human hook the lead to the bull's collar, motioning that he should follow.
The first thing he noticed when he walked with the handler was the scent of the heifer's collar he had grown accustomed to. His massive cock strained in the cage forcing a pained groan from behind his gag. He saw the heifer in the artificial field, looking at him. Seeing the bull finally in the room she twirled and shook her tail at him, letting out a seductive moo to entice him further.
B-4 looked up at the handler, the sound coming out pathetic as he begged to be let out of his cage. The human looked at the bull and then looked back to the heifer until the sound came again, longer and deeper.
"Remember. Dominate, not mean. If you try and hurt her, she will hurt you, then I will beat you bloody. If you fail this test, it is a week until we try again. A week caged, keep that in mind."
The bull nodded, the act of kindness in speaking he appreciated. Hands on the cage freed his cock and he moaned, growing hard just from the simple act. A click releasing the lead set the bull free.
