"Follow me, sow." Your trainer says as he leads you into a time bubble.

You're not very surprised when you see a large pig pen in the room inside the time bubble. The pig pen is filthy and full of slimy mud. There is also a very large feeding trough in it. Your trainer opens the gate to the pig pen and gestures for you to go inside. You silently obey.

"Good, beast." The trainer says, "Before I start feeding you, I need to make a few things clear. I'm a professional and I know exactly how much food a pig girl can eat. I will balance your food intake in a way that will maximize your weight gain without causing you to explode. As your training progresses, your stomach will stretch, allowing you to eat more and more food. If you want to win this test, you will obey my every command and eat everything that I put in front of you, is that clear?"

All your previous training kicks in and you reply without hesitation, "Yes, Master."

"Good, any questions?" Your trainer asks.

"Just one, Master." You reply, "If I win this test, will all the weight that I gained be lost when this skin suit is removed?"

"Maybe." The trainer says, "Magic suits can be a little unpredictable when it comes to weight that was gained naturally while the suit was being worn. There is a 50/50 chance that either any weight gained will be lost when the suit is removed or the weight gained will permanently transfer to your original body."

"I see..." You gulp nervously hoping that it doesn't happen to you.

"Enough talk, eat this." Your trainer smiles as he dumps two buckets of smelly pig slop into the trough.

All your training in obedience doesn't even allow you to hesitate. You plunge your head into the disgusting brown sludge and start eating it. It tastes horrible, but you obediently slurp it down. The stuff is so gooey that you're able to swallow it without chewing. You only stop eating once every couple of seconds so you can get a quick breath of fresh air, before plunging your head back into the slop.

The train smiles and starts fondling your six breasts as you eat, "I have to admit that I'm impressed, piggy. Most new pigs hesitate to eat slop the first time. You must be a natural piggy."

You blush, but continue to force yourself to eat the slop. Eventually you gulp down the last of it. Your belly feels painfully bloated and a quick glance reveals that is visibly swollen. Eating so much, has made you feel sleepy.

"Good, pig." The trainer says, "Now you go to sleep and let that food digest, then I'll give you more slop when you wake up."

"Yes, oink... Master." You grunt as you close your eyes and drift off to sleep.

...

Your days turn into a seemingly endless pattern. You wake up, eat pig slop, then go back to sleep and let it digest. The mindless monotony of it makes you feel like a real mindless pig. You swear that you feel a little dumber each passing day. This treatment increases your obedience to an even higher level.

Eventually, you get used to the horrible taste of the slop and you even start to enjoy it. You begin to look forward to each of your feedings. Each day, your trainer increases the amount of pig slop that he gives you by a small amount. At first, you're only eating two buckets of slop, but you're soon eating three, then four, then more and more. After each feeding, your belly is always so full that you're afraid that you're going to explode. It never happens though, your trainer thankfully know exactly what he's doing.

At first you don't seem to change at all, but as the days go by your body starts to feel heavier and heavier. Before long, you notice that your once flat stomach has developed into a nice sized pot belly. After that, every few days, you slowly notice parts of your body fattening up. You blush with embarrassment every time your trainer comments on it and twirls your curly tail with his fingers. He loves making you aware of your growing weight. He even positions several large mirrors around your pig pen, forcing you to see every change to your slowly fattening body.

Your thighs slowly plump up and even start rubbing together. A large double and triple chin forms around your neck, they're so thick that it almost makes you look like you don't have a neck. The cheeks on your face puff up as your ass bloats up larger and larger. Huge love handles form on your waist as your belly plumps up to ever larger sizes. Your belly is soon sticking out several feet in front of you and it fills your lap every time you sit down. Your six pig breasts also plump up as time goes by. Your body continues gaining weight like that as your training progresses.

...

"Well folks, two of our little piggies have returned from their time bubble and the last one should be back any second now." The Announcer says, "In fact, here comes the last contestant now!"

The audience watches as you're led out of the time bubble by your trainer. You waddle a few steps, then you have to stop and catch your breath. This is more exercise than you've gotten in six months! You're forced to walk on all fours, because you've gotten so fat that you don't have the strength to stand on two legs. The audience points and laughs at your pathetic display and also at how fat you've gotten. You blush and oink sadly, knowing what a huge ball of blubber you've become.

You force yourself to focus on the contest. You look at the other contestants and see that...
