[Female to Male, Bull TF, Breeding]

"I do not understand how you are able to be as you are, Milly."

"Mmmm? What, Satsuki, what part of me don't you understand?"

It wasn't often that the Class Rep decided to speak up like this. She was always a stoic and quiet type of girl, real Yamato Nadeshiko type gal. That was what they were called, wasn't it? Ah, she didn't study the Japanese that thoroughly prior to getting here as part of the exchange. She was much more interested in getting hands-on experience.

Sure, that meant that she stood out. She was an American after all. Plump but happy and proud of herself. Sure, she brought a couple of looks towards her whenever she wore her tighter shirts that ended up showing off her impressive bust or her tummy, or the pants that were way too tight on her butt, but so what? She didn't mind them staring, and she didn't act differently just because she was showing off. That was just how she was.

She didn't mind them staring. She didn't mind them lookin'. She just lived her life how it was. And having the Class Rep start asking questions? It was actually the first time somebody bothered to try and reach out in that sense. So of course she was happy to do so.

"The... Attitude, I suppose would be the right way to describe the issue I have with you." Satsuki spoke, only to blush slightly as she shook her head. "No, that's not right at all. That implies that I have problems with you, Milly. I don't have any problems with you. In fact, I very much appreciate that you're here. Even during cleanup like this."

Milly nodded as she took a good look at Satsuki. She was... Kinda the opposite of what Milly was? Not like, full on. But she was a lot leaner. A lot stronger looking than Milly too. Come to think of it, Sats-chan was in the Kendo Club, wasn't she? No wonder she had those big ol' trunks for arms. Maybe she was shy because she wasn't sure that she could be how she wanted to be? Her formal and gentle personality contrasting her looks... Yeah, that would probably bother a gal like her, wouldn't it?

"You're worried you can't really be like me, but not LIKE me. Yeah? Like, you wanna do things your own way and don't wanna worry about others and what they think?"

Satsuki blushed as Milly cut right to the heart of the issue. She was impressive even in that regard. Able to pick out exactly what the problem was, despite the Japanese girl having trouble properly clarifying herself.

"You really are impressive, Milly. Indeed. I'm worried that I won't be able to be exactly what I want to be." Satsuki said, as she put down the stack of books that she was meant to carry into the teacher's lounge. "I... I feel torn in several directions. My obligations, my personal pursuits, my aspirations, all of it is tearing at the little girl that once was called Satsuki..."

Ahhh. Yep. Yeeeep. Milly knew all about this. Seemed like Sats-chan was a kindred soul. She just went through this problem later than Milly had. Heh, guess girls like them really are the same when push comes to shove.

"I getcha. I getcha, Sats-chan." Milly said with a great big smile on her face. "I think I know something that might help you, if you're feeling that much doubt inside that big ol' smarty brain of yours."

Satsuki was left stunned for a few seconds as Milly not only gave her a cutesy nickname, but also called her a... 'Smarty brain'. Goodness, the American was not the most eloquent with words. But that simply served to convey her honest mind and honest heart.

"I... Do not believe there's a simple solution to my problems, Milly. But I appreciate the effort regardless..." She wasn't going to turn her down. Goodness no. But she just simply couldn't wrap her head around there being a potential solution to her problem...

Not until it was staring her right in the face. In the form of a big ol' bottle full of thick looking milk. Which just made Satsuki blink a few more times in a mixture of shock and confusion. What exactly was a bottle of milk going to do?

"This'll help. Y'know, my Momma was always telling me that whenever she needed my Poppa to grow a spine and man up, she'd slip him some of this. And then she'd make sure that he made another batch before he ended up retreating back into his shell." Milly said with confidence, even though her words were painting a vivid picture of exactly what this was...

Satsuki stared at it for a few more seconds before the gears turned. "...Are you saying this is what I think it is, Milly?" She asked, her tone growing slightly stern as she did so. Her eyes even growing sharp. "Why did you bring this sort of thing with you to school?"

"Ahhhh don't worry so much about it." Milly waved off the Class Rep's concerns, laughing a little as she popped open the cork on the top of the bottle. "Listen, just have a taste. And don't worry too much about the repercussions. The more you worry, the more lil' Sats-chan will end up getting lost in that big scary dark muck that's keeping her trapped."

Milly was... correct. Even though this was a very foul looking substance now that she got a better look at it. But if it really was effective as Milly implied it was, then... What did she have to lose, exactly? Not much, as far as Satsuki could calculate.

"... You will be going to detention for the next week, regardless if this works or not." Satsuki glared at her again. As confused as she was, she wasn't going to let her smuggling this thick and pungent milk to school slide. No matter what Milly said it was able to do.

After Milly rapidly nodded and gave her two thumbs up, she knew that she couldn't put it off any longer. She didn't want to refuse Milly. Not after she had gone through all this effort to go against the rules.

Satsuki took a deep breath...

And then tipped the bottle over as she held it to her lips. Letting it all slide out like the sludgy not-quite-milk that it was. Swallowing the thick substance bit by bit to ensure that she didn't end up choking on it. Even though it was still horrendously thick and chewy due to the density of the substance...

To her surprise, it didn't taste nearly as bad as it smelled like. Not only that, but once she had started swallowing a bit of it, it was like her throat was getting wider. Allowing her to get more and more down in a matter of mere moments. Allowing her to down the rest in what felt like a blink of the eye...

She even ended up dropping the bottle outright when she emptied it completely. All while the faint scent of the substance wafted out of her mouth, as she just stood there with a strange heat gradually starting to push its way through her...

It was like... It was like something was starting to ring inside her. And with that ringing came a pleasant heat. A heat that spread through her, from the core of her stomach all the way out into the very tips of her fingers and toes...

Then, the bell rung loud...

MMMMOOOOOOOO!

And a mighty mooing roar left her lips, as the potency of this 'milk' slammed its way through Satsuki. She wasn't prepared for this sudden surge of power. Nor this sudden surge of pleasure...

Her uniform was shredded to pieces as muscles bulged their way across her form, immediately doubling her size as she now towered over the American. All while more and more muscle started bulging out across her arms and her legs, making her look even bigger...

But while she was bulking out, there was one part of her that was particularly growing. And it was accompanied by a healthy heaping of throbbing between her thighs. A throb that was filling her mind with more and more of a hazy pleasure, causing her to tremble more and more...

It wasn't like the heat that had been pleasantly working its way through her body before. This was an intense heat. A heat that wanted to be released. Concentrating itself down there... And up on her chest too, as if something wanted to be let free there too. Something... Something potent... Something... strong... and...

MANLY.

moooooOOOOOOOOOO!

Once again, Satsuki let out a mooing roar. This time, it was because of what had burst free from her...

From HIS loins. Because instead of a fresh and still virgin pussy, there was now a fat cock where that femininity should've been. And HIS chest, which HE had been a little worried about given its rapid development? Replaced with a fat set of strong and bouncy pecs, with chest hair shaped like a bell having sprouted between those big strong masculine mounds...

He was... fuck, HE was... He had become a... Big, muscly, hypermasculine...

Bull.

Emphasized as such by the horns that sprouted from his head once his thoughts aligned with his body, leaving him panting and gasping as he gazed down towards the plump American that had helped him with that bottle of cum that had done this to him...

"Woah. Really did the job, huh... N-No wonder Momma... No wonder... Momma..."

It didn't take long for Milly to end up entranced by the manly musk in the air. She knew that Momma told her all about how strong and dominant Poppa was after drinking his own cum, but... Fuck, she could barely even think at this point.

Not that she really needed to. She just needed to lean... No, better...

She just laid down on one of the tables. Putting her rapidly soaking pussy at perfect level with that massive bull meat that was hanging from Sats-chan's... Sats-kun's crotch... She was ready for him to use it, just as Momma probably had been whenever she made Poppa drink this...

Satsuki stared down at the naked pussy in front of him. And the bull let out a deeply needy grunt, slamming his hands down on the arms of his mate...

He could barely even understand what was going on. Not that he had a problem with that. He just needed to breed what was in front of him. Right? That was what a Bull was good for...

Milly did feel a little worried as that massive thing hovered over her. It was so big that it was definitely going to destroy the door to her womb. And yet looking at it, she couldn't help but just feel excited...

The excitement quickly turning into an unimaginable and overwhelming climax as the cock slammed into her. She couldn't believe it. It felt just as good... No, it felt even better than she could've possibly predicted.

And once he was inside her? He just hammered away at her. Piercing through her cervix as he distended her womb around his cock. It didn't matter how tight she had been. It didn't matter how small she was. He used her. Abused her...

But it all felt wonderful. And it was all meant to be. Because she fit him perfectly. He fit her perfectly too... Fuck, they were made for one another..!

It didn't take long at all for this brief hammering to lead Milly to another climax. Her pussy wringing around that mighty thing, trying to pull the cum out of it...

Only for Satsuki to cry out and moo again, the bull breaking past her wringing defenses and slamming even harder. Right before the volcanic eruption that was his cum flooded its way out of there. Right before his cum exploded into her womb, bloating her in a mere matter of seconds...

It was just the first climax, and yet... Fuck, they could keep going for hours... Days... Weeks..? Fuck, she wanted nothing more than for him to keep breeding her...

Heh... Maybe after all of this was over, Sats-kun would understand what he had to do. But one thing was certain based on her tummy growing before her very eyes...

She was going to make sure Sats-kun became a good Poppa for their kiddos. And maybe, juuuust maybe...

Make him drink a little bit more of his own cum so this could happen all over again...
