“Please Coach, I’m still full from breakfast, can’t I work out some more?” Reggie said, rubbing his still full belly and letting off an uncomfortable belch. He was soaked in sweat, but he’d had a hard time lifting this morning, due to how full he was.

Coach just looked down at him, unimpressed. “You said you wanted to train with me, didn’t you?”
“Yes Coach,” Reggie muttered.
“And when I told you that I would train you, you remember what that meant right? That you would have to do everything I said. That if you wanted to be a bull like me, that was going to take some sacrifices. You’d have to do some things that you wouldn’t do otherwise.”
Reggie nodded.
“Besides, you are hungry, aren’t you?”

He was. He was still so full, but his lips were parched somehow. Coach tweaked one of his nipples, and a spurt of milk shot out of it and struck Reggie in the cheek. Unable to help himself, he scooped it up with a finger and sucked it clean.
“Now drink it up, and don’t question me again.”
Reggie stood up, and started sucking on one of coach’s teats, moaning as he did, his head going foggy and loopy like it always did when he drank down his milk. It wasn’t long before Reggie’s mind had shut down entirely, as he moved onto the other tit, grinding his cock and balls up against Coach’s body. Something…had been happening to them lately. The more of coach’s milk he drank, the larger his ball sack got, and the smaller his cock became, almost like his sack was absorbing it.
When he’d drained Coach’s teats, the older man pushed him away. “Now, what are you?”
“I’m a cow, Coach.”
“That’s good. And what are cows?”
“Cows are fat. Cows are stupid. Cows don’t have dicks, we just have udders full of milk for Master.”
“That’s good. You will remember that, you will know in your heart that you are a cow, but you will still think that you are here to become a bull like me. You still aren’t ready to know the truth of what you are, of what you want to be.”
Reggie nodded dumbly.
“Now turn around, time to fatten up that ass of yours.”
Reggie turned around and bent over the weight bench, and Coach fucked his tight hole, both of them mooing and lowing, Reggie’s smaller cock spewing milk all over the floor with each thrust of Coach’s massive cock into his ass. Give him another week, and then Coach would tell him the truth. He’d never come here because he wanted to be a bull–after all, there was only room for one bull in the herd. No, Reggie would join his brothers down in the basement, stuffing themselves, getting milked all day long, and help fuel Coach’s growing protein shake business instead. Then, Coach would find another wannabe, and show they that they would be happier as a stupid cow too.
