Now that Ulysses and Blueberry had left on their honeymoon, it was just Nate and Shuixing on the farm. Well, there was also Nate's aunt and uncle and the other uplifted cows, but they were giving the young couple plenty of space. Meryl and Olly were staying over at Strawberry's for the night, though Meryl gave her nephew a real earful about the ways he ought to be pleasing a woman. Nate wasn't quite sure how much of this was necessary as he wasn't certain if he and Shuixing would doing anything. Yes, he had been given his father's blessing and he could easily finish his last year of college online, which may be a necessity considering the current pandemic. But the decision was just as much Shuixing's as his and she seemed to be holding back.
There was only one real reason why Shuixing didn't want to convert Nate right now: her sisters. It's hardly that they disapproved of Nate, they were really glad that Shuixing had found someone who loved for who she was, inside and out. But Shuixing had a feeling they wanted to be involved in his conversion somehow. As such, Shuixing got online with them to talk with them. "So, everyone's cleared out of the house for the night except us," said Shuixing, "I mean, they're all expecting us to...well..."
"And you don't want to?" asked Jinxing incredulously, "All you ever seemed to talk about was Nate and how much you missed him. And now they're alone with him, you're not going to do it?"
"Well, I'm not sure what you thought," said Shuixing, "I thought you'd want me to wait until we're back on Heiya Island or something."
"Is that all?" asked Tuxing, "Shuixing, the last thing we want to do is get in the way of your happiness. You don't have to stand on ceremony for us."
"I could have thought for a few fun ways for Nate to get changed though," said Huoxing, pouting a little.
"Well, you can save them for your own boyfriend," said Shuixing, "I'm sure there will be boys lining up to date you."
"We do expect you to have the wedding here though," said Muxing, "No matter how long that would take."
"Of course," said Shuixing, "Besides, I wouldn't want to have it so close to Ulysses and Blueberry's wedding. So long as you don't mind having him around more often."
"Then what are you waiting for?" asked Jinxing, "Get in there and make him your bull."
==========
Nate dressed lightly for bed that night, just a pair of briefs. He didn't know if Shuixing wanted to make the first move. It didn't have to be this night. After all, his dad and stepmom would be gone for at least a week. It wasn't like there was a rush. But then Nate heard the doorknob move. He sat up as the door opened. Shuixing filled the doorway pretty easily. She entered and shut the door behind, mostly because her horns weren't ideal for lingering in the doorway. She was wearing a blue silk dressing gown and Nate was certain nothing else. "So your mind's made up?" asked Nate.
"I just had to take care of one last thing," said Shuixing, "But what about you? There's no going back from this."
Nate just looked her in the eye and said, "My mind's made up. I couldn't want you more."
"Are you sure?" asked Shuixing teasingly before letting her dressing gown slide off. Nate had taken some looks at Shuixing's naked body before, mainly at the hot springs on Heiya Island. He tried to be a gentleman and not ogle her. But seeing her bare before him, offering everything she was, he just couldn't look away. His briefs became very tented at that. Shuixing giggled before walking over to Nate's bed and sitting down. Like every other bed and other furniture in the house, it was reinforced to handle heavier Animalians. "Well, come on, Nate. You've got one last cow to milk," said Shuixing coyly. She pushed out her considerable udders towards Nate.
Nate gently cupped one breast, which was much larger than both hands could fully hold. Shuixing moaned a little as she felt her nipple already starting to dribble a little milk. But before Nate put his lips to that nipple, he used them to give Shuixing a kiss. Then he started suckling from her nipple. Shuixing moaned as her boyfriend, no, her mate, started drinking her unvacinated milk.
The changes to Nate's body became very apparent. The bed creaked a little bit as he put on more mass, though they were assured it could hold two large Animalians. Working on a dairy farm didn't make Nate scrawny or overweight, but it didn't make him more buff than the average farmer. This was changing as Nate's muscles swelled with new strength. What had been acceptable for farmwork was now surging into bodybuilder territory as his shoulders became much broader and everything between them and his briefs gained chiseled definition. Speaking of which, his briefs were starting to strain as his cock and balls grew larger humanly possible.
But now bovine features were becoming more prominent. Black hair thickened on his body, condensing into a short lair of fur. The stubble beard became swallowed up as the fur spread over his face. Nate found himself being able to hold more of Shuixing's nipple in her mouth as it started pushing out, canines flattening as his teeth adjusted to a pure vegetarian diet. His nose pushed out and broadened as his new muzzle formed. Shuixing playfully parted his hair, watching his new horns bud.
Nate's lower body was changing as well. His legs had grown very thick with muscle, they were also growing longer as his feet stretched out. His toes curled in on themselves before they were swallowed up by keratin, making very sturdy hooves. Above his ass, which had gained the muscular shape appealing to women, vertebrate were extending out, new nerves activated allowing him to swish his new tail. The underwear beneath that tail was reaching the limit of what cotton and elastic could contain of those dimensions. With one final rip. his briefs were torn asunder and his longer bovine cock sprang out and slapped Shuixing's waist.
The feeling of this jolted both Shuixing and Nate out of their daze. Shuixing looked her soon-to-be-mate over. If his transformation wasn't complete now, he was a very attractive water buffalo bull. They seemed to be at the same height now, so he may not be finished changing. His horns were probably going to get a big bigger now. But Shuixing found herself staring down at the large cock he was now sporting: long, thick, flattened end, and a pair of fist-sized balls. Well, human fist-sized, not the large hands Nate had now with keratin tips.
"Oh, Nate," said Shuixing in a husky voice, "I need you. I need my bull." With little resistance, Shuixing pushed Nate further onto the bed and was soon straddling him. Her weight would have crushed him earlier, but now he looked like he could carry her weight and then some.
"Uh, I'm not as familiar as most fellas," said Nate a little nervously, his voice sounding deeper coming from his broader chest.
"Don't worry," said Shuixing, "Let me show you what I picked up from that cult." While it was true she was no virgin, she wasn't quite prepared for how much Nate's cock filled her as she lowered herself. A human woman would have been torn apart. Her 'cowhole' was stretched out, but not unbearably so. After getting used to his girth, Shuixing soon started bouncing.
Things dissolved into a pleasurable haze after that. Shuixing was able to lead Nate through several sexual positions that may not be so apparent to beginners. It was a good thing no one else was in the house the sound of their banging, moaning, and the occasional mooing would have woken up everyone. Though it was pretty easy to imagine Meryl's long ear twitching as she heard her nephew getting it on.
Some point long after midnight, Nate and Shuixing had settled down to sleep. Not much point in pulling up the sheets, they were going to need a wash in the morning. Shuixing cuddled up to her bull before kissing him. "Wǒ ài nǐ," she whispered.
"I love you too," said Nate. He had a few parting thoughts as he drifted off to sleep, like what their wedding would be like. But that wouldn't be until a long time from now. The only thing that mattered was they were mated.
