Changing for the best (transformation)

"It's a bit weird, your party, Sarah." Jane said.

"Come on, it's fun!" She answered.

Everyone was naked since it was an orgy, and there were several costumes hanging around to play with, some with dressed with just a collar, acting like pets, others were wearing various costumes, acting the part. Sarah wanted to try, but didn't want to go alone, so she asked Jane to come with her.

Looking at the costumes, Sarah picked a waitress outfit, while Jane just put on a twin pigtail wig. They then went seeking a partner. Surprisingly, there was no one looking unattractive, so the brunette didn't have a hard time to find someone.

"Good afternoon. What can we serve you today?" She said naturally.

"You, I'll take you." The man answered.

"Of course the main menu."

She went on her knees and started to suck his cock right there. It was actually fun for her to play her role, like it was natural.

On the other hand, Jane was having some difficulties to join the fun and watched for a moment. But she was really getting horny and looked at some of the dildo at disposition. Picking one of them, she started to play with it in front of everyone.

"Like, O.M.G. What am I tots doing?" She thought out loud.

Sarah finished of the man, liking and sucking the cum from his softening member. She really had fun doing it, and wanted to go further when the man stopped her.

"You're nice and all, but can I chose a costume for you?"

Confused, at what he was talking about, before remembering she was wearing waitress clothes and not being actually one.

"Oh... Yes... Sure!"

The man picked cow patterned stockings, cow patterned bikini top and mini skirt, and cow horn and ears on a headband. It wasn't her kink, but she was horny after sucking him, she accepted.

Once put on, they resumed what they were doing to her great pleasure. Kissing and fondling each others he freed her tits that somehow looked bigger than usual. With his hands on them, kneading them like dough, they were feeling so full and sensitive.

"Oooh... fuck... that feels great!"

"I know my little cow."

She usually didn't like that, names little she's some... but it strangely felt good this time. What she wasn't much liking was feeling his cock pressing against her back door.

"Hey! Not there!"

But went in without really any resistance, surprising her. She was getting anal fucked, but it wasn't bad at all.

"Mooo! Fuck!!" She let out.

What was going on with her? Did she moo?? And why did she like all of this so much?!

Jane was not far. Unlike her friend, she was too horny to notice her changes. Blue eyes, long blond hairs, big fake tits, plump lips and pussy. She was fucked her brain out, literally.

"Ooooh, fuck Jane! Yes Jane loves it sooo much!!!"

While the night was closing to its end. Sarah was on a milking machine, with her tits absolutely huge and her nipples looking more like teats. The man she was with was fucking her pussy, playing with a buttplug in her ass.

"Mooo! Ye-mooo!!" She was saying, barely able to speak under the pleasure and just mooing.

"I wish I could bring you back home, my little cow, but the magic only work here. Still, I'm sure, you'll come back, they all do."

Few months later, Jane and Sarah were hanging on the beach of the brunette's boyfriend summer house.

"Can you stop taking off your clothes?"

"They're uncomfortable on moo teats... Mooo... and the lower part is always from moo drooling pussy... Mooo... We're alone anyway!"

"They told you that, like, using too often the same stuff on a short time period could totally leave permanent effects!"

Indeed Sarah's body was greatly changed, with huge tits, massive nipples, bubbly ass, and a wider nose. The nose ring was a gift from her boyfriend.

"Like you're the moo, one to talk! You've becomoo a total bimbo slut! Mooo!!"

"That's, like, soo not true!! I used the doll stuffs too!"

Indeed, Jane looked like a living sex doll and had a hard time saying no to a man, especially with her constant state of arousal and low IQ.
