"13", said Tracey with a smile, thinking about how Tom would look like at 13.
"13, are you serious, that is really young", answered Janet with some confusion.
"Yes I am serious, didn't you ever think about losing your virginity when you were 13?", smiled Tracey rubbing her 5 month pregnant belly.
"Yes, what girl hasn't, but..", replied Janet.
"No buts, here is our chance to lose our virginity at age 13 with all the knowledge we have now. Besides it will be interesting to see Tom and Fred as young teens.", said Tracey.
"Okay you convinced me, but what about Crystal and Sarah, I do not want to lose her?", asked Janet while looking down at her pregnant belly.
"Oh we'll put them into storage in our ovaries so we can be virgins again. Don't worry, we'll bring them back after our fun.", explained Tracey.
"Are you sure this is a good idea?", asked Janet selecting the correct settings for Tracey's plan.
"Yes it is a great idea, are you wimping out?", asked Tracey.
"No, it is just I got a funny feeling that something will go wrong", answered Janet looking at Tracey.
"You worry to much, just click away,", said Tracey.
"Okay, here goes nothing", said Janet as clicked on the changes.
Janet and Tracey watched as each others bellies began to shrink away. When their bellies showed no traces of being pregnant a funny look came over both of them. A sudden burst of an orgasm hit them as Crystal and Sarah reached the point of conception.
"Wow I never expected that", said Tracey with a sigh.
They watched as each others breasts firmed up and then began to shrink as they entered their teens. Their panties were changing to more of a teenage style and the guest room was changing into a teenaged girls room. At 17, Janet felt her hymen reform making her a virgin again. Thier breasts continued to shrink back in sizes as they grew ever younger. At 15, Tracey felt her hymen return, making her smile. 14...13.. they reached the age Tracey suggested.
Janet's blonde hair was down to her shoulders and a slight sprinkle of freckles were across her upturned nose. Her breasts were almost flat, not even much for a training bra. Janet's panties were now a childish style with little flowers on them. All her curves were gone and she was now skinny. The room around them was now a little girl's room that suggested that the girl who lived in it was not far out of childhood.
Tracey's brunet hair was pulled back into a ponytail and down to her mid back. Her breasts were bigger than Janet's and were able to fill up a training bra easily. Tracey's panties had turned into a childish style of pink panties and she was also skinny as Janet.
"Wow look at us, it looks like we just entered puberty.", giggled Tracey pointing at Janet's chest.
"Yea I have no pubic hair to speak of.", said Janet as she pulled her panties out to look at her groin.
They took a few minutes to look each other over at the changes that had happened to them. Then Janet spotted their discarded clothes on the floor.
"Hey look, our clothes have turned into school uniforms", said Janet looking at the two pair catholic style clothes on the floor.
"And look, this is your room. Look at that cute picture of us at your 10 birthday party. We were adorable.", smiled Tracey.
"You're right, we were adorable.", said Janet looking at the picture on the desk by the seventh grade textbooks.
"Come on, let's get our clothes on and go downstairs and meet the boys", said Tracey as she started to put on her uniform.
Soon Tracey and Janet were done putting on their uniforms. They were both wearing a white blouse and red neck tie with a blue vest and a blue pleated skirt.
"Wait until the boys see us", giggled Tracey turling around.
Nerveously, Janet followed Tracey downstairs to join up with Tom and Fred, who were now also 13 years old. Janet did not know why she was nerveous, maybe it was that funny feeling she had before about something going wrong. As they entered the living room, they spotted two young boys playing video games on the TV.
"Boy do they look cute.", whispered Tracey into Janet's ear.
"You two took forever to use the bathroom, I do not know why girl's take so long.", said Tom spotting Janet and Tracey entering the room.
"Hey Jan, do you want to play?", asked Fred looking at Janet.
"Sure," said Janet as she walked over and sat down next to Fred, her former husband now boyfriend.
"Here have my controller, I need to pee", said Tom as he got up and walked toward the bathroom.
Janet took it and started to play with Fred, not really knowing what to do. Meanwhile, Tracey followed Tom to the upstairs bathroom.
