Gloria watched as her accidental wish started changing the trick-or-treaters. The kids started growing older, their costumes growing as they became taller. Their styles also became to alter. The little vampire's costume started turning darker and more stylish. As his face went through puberty, makeup made him paler, accenting his eyebrows and reddening lips. But they also enhanced his sharp good looks. The mummy girl's bandages were altering and unwinding slightly. Bare skin became more visible between the gaps. Her bandages left her belly uncovered as it became more toned. Her breasts swelled out to a respectable size for her age, with the bandages parting to produce an effective cleavage window. There were also more accessories, namely Egyptian-themed jewelry and a cobra-headed tiara perched on her head, which now had her hair in a class Egyptian bob. The superhero kid grew pretty tall, his muscles growing larger. His costume became a lot less cheap and served to emphasize his muscles even more.
But the trick-or-treaters were the only ones changing. Their parents became much younger, signs of old age being erased. Their clothes also changed, becoming opposite-gender counterparts of their kids'. Or rather former kids. The vampiress and superheroine, now wearing sexy costumes that showed off their curves, were clinging tightly to their new boyfriends' arms. The mummified pharaoh now had his hand on his undead queen's shoulder.
"Heard you were throwing a cool party tonight," said the superhero.
"Well, yes, but it's mostly for my friends," said Gloria.
"Then it's going to be your night to make more friends," said the mummy girl as she walked in.
"Hope you have enough food," said the vampire as he tried to walk in.
"Ah, ah, ah, you know the rules, Damon," said the mummy girl, "Vampires have to be invited."
"Are we really doing those rules, Libby?" asked the vampiress, "She's a vampire and she's inside." She pointed at Jackie's costume.
"She got invited, right?" asked Libby, asking Jackie.
"Well, yeah," said Jackie.
"There you go. Gotta get invitations first," said Libby.
"Uh, can't you invite her?" asked the superhero.
"Has to be someone who lives in the house, Clark," said Libby.
Damon looked at Gloria and asked, "May I and Cammy come in?"
"Uh, sure, the more the merrier," said Gloria.
"Awesome," said the pharaoh as he and the rest walked in.
"Thanks a lot," said the superheroine, "This is going to be such a good time."
While the new guests headed for the refreshments, Diane said to Gloria, "Nice going. You going to invite everyone who comes to the door?"
"It wouldn't be so bad," said Naomi, "We could have a big teen party."
"If we're gonna have a big party, we might as well make it a college party," said Sasha.
"I think the gender ratio would be way off for a college party," said Jackie.
"But there's bound to be more boys coming," said Felecia, "Could be a lot of fun."
"Give me a moment to think," said Gloria. A bigger party did sound like fun. But she wasn't sure if she could keep changing everybody into teens. There were enough students at the high school as it was already. Making it into a college-age party was very enticing, though it could get a bit out of control. Though obviously nothing was going to permanent, Gloria wouldn't want her parents coming home to see a bigger party than they expected. But did she really want to risk it?
