Hello everyone, I'm looking for a story I vaguely remember. It was about a man having invented an Age Regression machine in his _base_ment. He invite others adults, maybe four or five, to witness it. I think they were all holding important position in the small town, like sheriff.
Meanwhile, his son and others childrens witness from behind the _base_ment upper windows as the adult use it to temporarily make themselves kids again.
The childrens barge in and feign not to know them, accusing them of being tresspassers and stealing clothes, menacing to call the police. Frightened, the adult made kids agree to do all the shores the childrens had been assigned at the start of the story.
Eventually, they're able to get back to adulthood.

Does it ring any bell? Would be great if someone knew what was the _title_ and author. :]
