Spencer found he kept having to adjust himself as he drove his precious cargo back to his family farm. While Spencer had jacked off more than once to the idea of transforming his school's most popular stud into a cow, the act of actually doing it was 100 times more exciting. Spencer could hear Chad chomping away chewing its cud and oats in the trailer through the open back window of his pickup . This was going easier than expected.
Chad for his part was enjoying his weird "dream". He was surprised to see Spencer in his dream, but it made sense. Spencer was both a farmboy hick and a science nerd. Chad had also caught Spencer watching him around campus: in the locker room, on practice field, in the cafeteria, and walking across campus. He just figured Spencer was gay and daydreaming of what he couldn't have. Chad had been flattered. So having Spencer give him a hand job by milking his four penises also made sense. Damn, Chad was enjoying this dream. He had four cocks and had just had multiple orgasms producing buckets of cum or was it milk? Did it matter? It was all a dream. Being able to analyze his dream while he dreamt was really cool. He hoped he would remember all this when he wakes up. These raw oats are delicious, he thought as he chomped happily away.
The trailer lurched as the truck and trailer left the road and started up the private drive to Spencer's family farm. Chad was miffed that a bunch of oats spilled on the floor of the trailer mixing with the cow paddies that Chad had dumped while he ate.
The trailer doors opened behind Chad. Spencer shouted, "Welcome to your new home, Chad! Come on, lets get you out of the trailer, and into the barn." Spencer led Chad by the rope securing the cowbell around Chad's neck. Spencer said as he led Chad by stalls filled with cows, "You were the stud at school, wait until you meet our farm stud." Chad snorted, as if to say I'm the stud.
Spencer snickered, and led Chad passed a couple empty stalls to an oversize stall with a winch attached to a sling. Chad soon himself harnessed into the sling, and immobilized.
Spencer started to giggle uncontrollably. He moved several wooden barriers, so there was only one route between Chad and the bull's stall.
"Hey, Ferdinand, I got a treat for you," Spencer said. The bull skittered back as Spencer opened the stall. Usually, this meant that the bull would be strapped in the sling and have his semen forcibly collected. Ferdinand sniffed. He smelled a new female in heat. He stepped out of the stall, glared at Spencer on the other side of the open stall gate. Then he trotted rapidly to toward the scent wafting from Chad's backside.
"Mooooo!" Chad shrieked as the huge stud bull raped him.
Spencer grinned from the side of the breeding stall as he recorded the scene on his phone. The nanobots only shifted Chad's DNA into that of a bovine, but hormone levels would determine whether Chad remained female or became male. But Ferdinand was ensuring that Chad would be a cow forever or at least until Spencer reversed the nanobots.
Chad was unhappy restrained in the sling. But when he smelled the horny bull approaching, Chad panicked and struggled to escape the sling imprisoning her. She felt the heavy mass of the bull mounting her. Then three feet of bullhood impaled her, and what felt like gallons of cum gushed into her.
Chad wasn't dreaming. He was a cow. Spencer had changed him into a cow. Tears welled in Chad's eyes, as Spencer explained that by breeding Ferdinand with Chad, he had guaranteed that Chad would remain a cow, and about a year, Chad would be a mother.
The bull seemed to really be enjoying himself. It wasn't just the first time that Chad had sex with a bull, it was the first time Ferdinand had sex with a cow. Spencer's dad ran his farm the scientific way. So Ferdinand's semen was collected by technicians who froze the sperm then would later artificially inseminate the herd.
Chad was painfully aware that he was no longer a human stud. The realization that he had been impregnated by a bull was something his mind struggled to accept. He - er, she- was going to be a mother?
