There was Myron.
Now Myron wasn't bad looking, in fact he was hot for what most would consider. 6' 180 pounds of pure muscle. I don't think there was an ounce of fat on him.
He had been watching Jeff and he knew something was going on with those rubber panties. He tugged them on over his thick thighs.
Pulling Jeff up over his mammoth cock was no small feat. It pressed hard on his tight ass and even more on his beer can cock. This along got him hard and he couldn't help but rub at the rubber panties pressing into his dick.
As he massaged it he got harder and harder and the rubber panties wouldn't let go of the end of his cock making him hornier. As Myron was about to explode Jeff began to form at the seat of Myron's panties and was sucked up into his ass. It wasn't long before he was attached to the inside of Myron just like a woman would have attached a baby with an umbilical cord and just as Myron orgasmed Jeff was completely inside of Myron.
But unlike a woman Myron had a full grown adult in his abdomen. It pressed out at his belly and had nine months before it was going to be released through his ass.
This was not going to be good on his body. The stretching alone gave him angry stretch marks all over his stomach and Myron would try to work out but he would be quickly exhausted and give up.
He waddled from the moment Jeff entered him but it got more pronounced as he got fatter from the lack of exercise.
His legs formerly all sinewy were now mammoth logs of fat and very little muscle. His pecs became breasts, filled with milk ready to feed his child.
He grew double chins hiding his neck completely but you wouldn't have noticed that since he also grew a beard and looked like a lumbering lumberjack.
he wore both a belt and a set of suspenders to hold up his size 80 pants and the 8xl shirt looked like a table cloth when washed and a moo moo when worn.
Myron was never going to get his body back but it was also Jeff that was changing inside of Myron's body. The lack of exercise inside of Myron made him the spitting image of his new daddy.
And he soon came ready for his rebirth.
Both Myron and Jeff were ready for the release but Myron's ass was never going to be the same after that.
