That night was nothing but a wild orgy. Jeff figured out how to do a 'were-change' setting on his giant two-dicked devil-form so he could switch back and forth, and he did all of them in that state, including the body. And when he would relax back into human form, he would find that the young furries with penises (including his sister!) would grab him and do him like he was a girl.
The next morning, when everyone was still asleep, Jeff did the final changes he would do to himself - he made his body firm and athletic, gave himself a vagina (hell, if all these penises were going to be using him, why not?), and made the ability to switch back and forth from seven-foot devil-form permanent. Little Rosie woke up first and was watching cartoons and asked if she could be a fox-girl like a character on "Tinytoons". Jeff thought it sounded okay and made the change and made her normal height as well.
School that day was an experience.
Jeff was suddenly an athlete, and girls (and a couple of boys) of his eighth grade class noticed immediately; Jeff decided that he liked the attention.
In the sixth grade, Alex Witherspoon the bunny-boy was whispered about, but the girls thought he was adorable. And in the locker room, his 6-incher (larger than most boys his age) brought some measure of respect.
Julie Witherspoon was now a small and sexy elf-girl wrapped in silk scarves (there being no clothes for someone her size) suddenly the class genius (an 18-year-old mind among 10-year-olds) and the sensation of her fifth grade class.
In another fifth-grade class, Rosie was a foxgirl with round firm tits. She loved being petted and stroked on her soft fur. And during recess, she showed off her new breasts and penis and all the fun sexual games she had learned to play. These games caught on, and the buses were late because a significant part of the fifth grade couldn't be found for most of an hour.
In the thrid-grade class, Jim Witherspoon showed off his new catboy body and power to change into a large cat. He came to class naked and got away with it, and loved it. During recess, Jim found himself being stroked and petted, and when the inevitable erection came up, he let one girl stroke it and showed off his ability to ejacualte. Several other boys decided to get in good with the girls that way, but not all of them were willing to see it.
In the first-grade class, young Katie Witherspoon also showed off her new catgirl body and breasts and penis (also deciding to come to school nude). During nap break and recess, she let the other kids explore her body and played spanking games. The poor teacher tried to control his hard-on by thinking of baseball.
When they got home, Katie and the younger kids played with their new pony. Jeff and Julie discovered that their mothers had been busy. Edith and Angelina had cleared out their bank accounts (including that of the pony-ized and unmourned Rev Witherspoon) and mortaged the houses and bought a church. They had decided to set up a new religion of a nature and fertility god who gifted His followers with pleasure and new bodies. Jeff decided he liked the sound of it.
Their first Saturday meeting was a hit. The two families' transformations had become the talk of the town, and now they were "explained" by the new religion. Angelina (a tiny angel) and Edith (a huge sensual cat-woman in a very sheer shift) were popular preachers. Julie (in a very sexy elf-girl gown) would take up collections. Jeff would hide under the pulpit with the Chronivac and scan any "converts". His changes would be either whim or based on their fetishes, but he gave them all healthy ages (usually between 15 and 30) and increased libidos, plus a five-minute delay. Then he would emerge from the pulpit in his devil-form, give a "blessing", and the new converts would transform. The first time it happened, it led to a near-riot; later meetings would expect it, and it would be merely dramatic. Of course, the fun part was the after-service "confirmation", which was just an excuse for an orgy.
In a month, the Church of the New Flesh was the major religion in town - because the only old, unattractive, and "normal" people were die-hard Christians who wouldn't go near the "devil's den". The streets abounded with cat-people, fox-people, bird-people, angels, devils, elves, tiny mouse-people, minotaurs, shapeshifters (or "persons of dual-shapes" to be PC) of various sorts, and seven-foot titans and amazons. And about a quarter of the women now had penises as well, and ten percent of the men had vaginas. All were healthy and in the prime of life or younger (Some ridiculously so - many old people insisted on becoming extra-young and were back in elementary school and knocking hell out of the grading curve.)
Jeff liked the changes. He had a sexy girlfriend, he was the son of a respected priestess, and he was popular. Not to mention the school was much nicer - breaks and P.E. and lunch periods had become sexual free-for-alls whenever the kids of New Flesh converts met, and everybody was relaxed and mellow.
The crime rate was down, because many of the worst people had disappeared (Jeff's Chronivac listed fetishes, and if things like 'murder', 'torture', and such popped up, Jeff gave them a one-hour delayed change to a fish). Because so many people were doing it, "indecent exposure" was no longer considered a crime. Incest had become a rather widespread fetish, and people mostly ignored it (unless it was something like Pastor Smith and what he forced his kids to do - but divine judgment found him when he went to the Church of the New Flesh to "exorcise the demons" and was turned into a fish).
It was a good life.
