Nate decided to go for a cows udder just for the hell of it. He didn't believe that the program really worked, so he put it in as some joke. "Would you like to enable changes?" Nate clicked yes. "Alrighty 'Mr. Magical machine'. Let's see you pull that off." Nate said ignoring the big bulge in his crotch area.
Jake had heard everything, despite his thick mane covering his ears. "He doesn't believe it... He's gonna grow an udder!" Jake's concern for his roommate caused him to push the door full force.
Nate was staring at the screen, when he saw the bathroom door burst open. "Nate, Stop!" Nate fell out of his chair in surprise as Jake yelled. Recovering on the floor, Nate got a look at Jake and noticed he was a little... No... ALOT hairier. "Jesus Jake. What up with the lion wig? You get to play Simba in the play or something?" Nate asked laughing. "Nate, this isn't a wig. It's real! As real as your udder will be!" Nate laughed even more. "Yeah sure. Gotta admit, you put alot of effort into this prank. I gotta commend you for that." Jake face palmed himself. "Okay... If this is a prank, why are your pants bulging?" Jake pointed to Nate's crotch area. "Hm?" Nate looked down to see his there was a bulge. His pants had actually felt getting tighter. "Huh... Oh... Oh God!" Nate finally realized the gravity of the situation.
He quickly unbuttoned his pants and pulled down his boxers to see pink flesh emerge from his groin, completely void of male genitals. "Oh... It's... Getting bigger..." Nate moaned as he felt his pink bulge growing round and pudgy. Jake looked in horror as he saw what came next... The tests. Nate's pink bulge started growing nubs. Four nubs appeared at multiple areas of his groin, pulsating into big nipple like bumps. "Gah... AHH!" Nate started moaning even louder closing his eyes, as a white liquid started emoting from his new tests. Nate, being curious enough, opened his eyes and began to grab one of the tests. Nate's expressions quickly changed to a smile, his tounge hanging as he rubbed the growth. Jake looked at him in complete confusion. Does he actually like that? Nate started pulling at he's fully developed udder, spraying milk across the floor, not caring where it landed. "Dude... This actually feels great. It feels like masturbating, but with four dicks." He said, still spraying milk all over the floor.
Finally getting over his pleasured state, Nate climbed back up to his feet. "So this thing really does work? That's how you got that crazy hair?" Nate asked excited. "Yeah. It's actually badass. It could also change reality, making people think this is normal." Jake explained, stroking his mane. "Except, I forgot to add that on when I grew this beastly thing." Nate started stroking Jake's mane as well. "Gotta admit. It looks hot on you. I bet you'd get a date easly... At least, easier than me..." Nate laughed, sloshing his udder.
"Yeah. Anyway, I should change these things to be normal. Uhh... Did you want to keep that?"
