As Luke stuffed his pig dick into Curtis, Ryan watched on rolling in the slop.
Curtis developed teets and having been fucked by Luke he became a female pig and was now pregnant with a litter of piglets.
It was then Ryan's turn and even with being exhausted by impregnating Curtis he was easily able to overpower Ryan and Ryan too became a pregnant sow.
114 days later both Ryan and Curtis gave birth to their first set of piglets.
Each giving birth to a dozen piglets.
Luke just continued to eat and get fatter while the other two become heavy with their litters.
Soon after they gave birth to their first litter Luke was on them again getting them ready for their second litter. He would impregnate some of the other sows running around, some true pigs and some other humans turned into pigs.
He was quite the stud having hundreds of baby piglets running around being fattened up to become bacon or sausage etc.
It was 3 years into their change and they had all but lost their humanity. Glimpses of their past lives would pass through their little piggy minds, none more so that the night they came to get Luke.
He had spent all his usefulness and was now going to be the main dish at the barbecue. Ryan and Curtis watched from their pen knowing that their friend had been slaughtered and would soon be digested by they partiers. And they wondered when they would be next.
But they weren't. for years they ate and produced litter after litter.
It was good 8 years of producing piglets when the farmer came to their pen and released them from their duties.
As they changed back into humans they realized that they didn't change back to themselves. They both lay in the mud. a good three times the size that they had started out at. Ryan was almost 800 pounds at his 6'3" frame. And Curtis was Near enough to 600 and that looked even rounder than Ryan on his 5'6" frame.
Having been wallowing as pigs for years they had the muscle to hold up their bodies but having been trained for years to enjoy food and sex they would never slim down. And although neither one was gay they now lusted after men to have sex with, no longer desiring the attention of women.
Saggy tits kept filling with milk ready to be drained and even though they both got their penis back it was so small that it disappeared inside of the apron of fat hanging at their crotch.
