He finds out one day that his buddy needs some help with his farm. The guy is a full farmer, that grows his own fruits, vegetables and has livestock. His buddy asks him if he wants to come up for a bit and help with things, so Benjamin agrees. They have been good friends since high school, so it would be good to see him again. He packs his bags, a week's worth of clothes and then heads out to the farm. It's in the middle of nowhere, in some fields of corn and wheat.
When he arrives, he gets off the bus, and waits for a few moments as his friend drives up to him. Benjamin looks over, as he sees the fields and then he looks at the farm. The barns, the animals, the pens. His eyes get fixed on a huge bull in one pen. He looks at his testicles and how big they are, hanging down almost to the ground. He gets lost in a thought of what it would be like, having that kind of power. He is snapped out of it as his friend arrives.
He gets into the truck and then they head to the farm house. They talk the whole way, catching up on everything that has happened in their lives. They finally arrive and get some food. After some time talking, his friend gets up and asks Benjamin to follow him. He leads him outside to one of the barns and then goes inside, with Benjamin right behind him. He looks around, seeing all the pens that are filled with cows and bulls. His eyes find a particular bull, as his friend stops in front of it. The bull looks at them and then Benjamin stares at it, thinking of what it would be to be a bull like that. What kind of life would he live, a life of just breeding.
He comes out of the barn a few minutes later, with a pair of overalls on. He has a white shirt underneath, and he puts a hat on. Benjamin goes back over to the bull, as he looks it over. His friend comes back over and then tells him the plan. The first cow is due to be bred and his job is to guide him through the process. He nods his head as he agrees with his friend. His friend gives him some directions and then tells him to bring the bull back with him, once he is done.
Benjamin opens the gate and then pulls out the bull. They walk over to the first pen and then he finds a cow that is ready to be bred. He puts her in a separate pen and then brings the bull in. They look at each other and then Benjamin watches as the bull slowly begins to get a hard on. His penis starts to grow out of his sheath, until it's fully out. It's huge and Benjamin watches in awe, as the bull starts to try to mount the cow. The bull does this a few times, as Benjamin watches from the side. The cow is moaning and then the bull mounts her. He slides his penis inside and then starts to thrust in and out.
Benjamin watches as the bull fucks the cow, as he thinks of what it must feel like. He thinks of what his dick would feel like being inside the cow, as he fucks her. The thoughts are interrupted as the bull moans loudly. Benjamin sees that his cock has gotten much bigger inside of her and then it starts to shoot semen inside of her. He watches as it finishes and then the bull comes down from his high. Benjamin looks at him and then he leaves him and the cow in the pen together. He closes the gate, as he goes to get another cow for the next round. The same thing happens for the next few hours, until they are all finished.
Benjamin pulls out the last cow and then watches as the bull fucks her. This time he gets really into it and moans with them. He closes his eyes and imagines that he is the bull fucking the cow, filling her with his cum. He can feel the weight of his testicles behind him, swaying back and forth as he thrusts into her. He feels the stretch of his penis as it goes deeper and deeper inside of her. Benjamin opens his eyes as he hears the bull finish. He watches as the bull's penis comes out of his sheath and then slides back into it. He pulls out of her and then Benjamin helps them both out.
The next day Benjamin is out in the field, bringing out the next cow to be bred. The bull is already in the pen and Benjamin looks at it. He looks it in the eyes and then looks at its huge testicles. He starts to imagine himself as a bull, being able to breed cows. He imagines what his life would be like as a bull. He gets lost in his thoughts for a few moments and then he comes back. He puts the cow in the pen and then he watches as the bull tries to breed her. This time, however, something strange starts to happen.
Benjamin feels his feet start to tingle, as they start to grow. The overalls he is wearing, start to tear at the bottom. He feels his legs change shape, as he looks down and watches them. They get covered in black fur and then his shoes and socks fall off. His feet turn into hooves, as he feels his weight become more stable. The overalls continue to tear and then his pants do the same. He feels a tail grow out from behind him, as he looks down at it. It's long and has a tuft of fur at the end, just like a bull's tail.
Benjamin looks up to the sky and then his face starts to tingle. He feels his nose stretch and then change, as his ears move to the top of his head. His face morphs into a bull's face and then he feels his testicles change. The overalls and his pants continue to fall apart, as his dick changes into a bull dick. He looks down as it falls out of his pants and then he watches it stretch out from his sheath. He feels a huge ball sack hanging below, as it swings back and forth.
The bull and cow look at him, as they can see the change happening. They don't move, as Benjamin looks over to them. His new bull brain is starting to take over and he moans as he gets a hard on. He watches as his penis comes out of his sheath. He has never felt so alive, as he sniffs the air and then goes towards the cow. She moves slightly, as he approaches her. He sniffs her again, as she lays down in front of him. He smells her heat and then mounts her. He thrusts his cock into her, as he moans with her. His testicles hang below him, swinging back and forth with each thrust. He fucks her for a long time, as his mind is filled with thoughts of sex. His moans are filled with pleasure, as his tail swishes back and forth. The bull watches as they fuck and then comes over and sniffs them. Benjamin continues to fuck her in the pussy, as their moans fill the air. Benjamin is now the bull, as his life as a human is now behind him.
