"Transform!" Jen blurted out.
"Haha, thought so. You love those huge boobs of yours, right?" Kyle sneered.
"What the fuck, you perv!" Jen responded, offended. Of course, as the head of her cheer team, she was quite well endowed. Didn't mean this creepy little freshman should be looking at her like that, the creep.
"Well, Jen, for your transformation, you're gonna get an upgrade, from melons to udders! That's right, as soon as I hang up, your boobs will each turn into a massive cow udder."
"I don't have time for this bullshit, you fucking weirdo! Wait, why can't I hang up??"
"You can't hang up until I finish your curse, bitch! Those new udders of yours will require milking at least once per day, like a true dairy cow. And good luck trying to keep up during cheer practice, because they'll be heavy! Now, now, I don't want to be too mean. Everyone but you and me will think that you've always had those huge bovine udders instead of human breasts, though it'll be treated like a freak mutation or something. People will stare, point, some may even poke your udders or pull a teat, if they're more brazen. Hope you like your new life, cow!"
Kyle hung up. Jen slammed her phone down, beet red with anger. What a fucking pervert! Just then, however, she froze. Her chest felt... warm. She looked down and watched as her boobs swelled before her eyes, growing and aching. Her skin began to turn pink, and a light fuzz spread over her expanding chest. As they grew and sagged, they began to pull her down with their increasing weight, until she was bracing herself on her bed. She felt them press on, against the bed, her arms, and down her torso. They were so heavy, she could hardly believe it. She felt her nipples tingle and harden, splitting into four each. They brushed against her blanket, sending a shiver up her spine.
Soon, her transformation was over. She groaned and huffed, pulling herself up, careful not to strain her back. She guessed each udder must weigh almost 50 lbs, maybe more. She thanked her strength training and exercise, but even then it was hard to stand. They swelled a bit more, a final 'fuck you' to the previously normal teen. She heaved herself down onto her bed, feeling them slosh onto her lap, pressing down heavily on her thighs. She looked at her full-length mirror. She was otherwise normal, but her torso was dominated by two enormous udders. She reached for a nipple, no, a *teat* and gave it a tug. She felt a small trickle of milk come out, though she felt... empty.
She heaved herself over to the bathroom, and, bracing her weight on the wall, reached down to pick up her bathroom scale. Her teats brushed against the cold floor as she leaned down, causing her to jump slightly. She almost fell, but managed to pick the scale up and return to her bed. She placed it under her massive, soft udder, and weighed it. 63 lbs!
As she recovered from the shock of knowing she was hauling around almost as much on her chest alone as she weighed just 5 minutes ago, a ravenous hunger came over her. Her udders demanded sustenance, and she felt them ache as her milk production began. She heard her mom call out that breakfast was ready, and braced herself to head downstairs. But first, she needed to get dressed.
