Jenny continued down the park walkway and noticed a 16-year old girl dragging what appeared to be her 4-year old sister to the bathrooms.
"But Becky, I want to go play of the swings!" screamed the preschooler.
"Hanna, first off it's Rebecca. I'm not a kid anymore. Becky is a kid's name. Second, we need to take you to the bathroom because apparently you still piss yourself. Ugh, why does mom make me take you here."
Jenny thought this was the perfect opportunity. She snuck into the bathroom before they got there and snuck into one of the stalls. She was able to see what was going on through the crack of the door. Rebecca was taking a new pair of pants and princess underwear for Hanna, when Jenna whispered. "Age Hanna's vagina 12 years."
Rebecca pulled down her sister's drenched pants and then her underwear and was shocked by what she saw. Her little sister's almost non-existent slit was growing bigger and hairier. Rebecca let off a gasp.
"What is it Becky?"
"Um...", Rebecca said, "I think your um....nevermind we need to get you dressed and I think I need to take you to the doctor."
"But Becky! I want to go play on the swings. "I saw Trevor over there and he's pretty cute."
Rebecca thought that was strange as Hanna never mentioned boys before. She was certain she saw her sister's now teenage vagina ooze a little bit as she was thinking of Trevor.
"Lets get your new underwear on."
Jenny was loving what she was seeing and wanted to continue. "Deage Rebecca's vagina by 15 years."
Rebecca felt weird as she was digging through the bag and then all of a sudden she felt damp. She looked down at her crotch and saw it was drenched in piss.
"What the hell?!" yelled Rebecca.
"Don't swear Becky!" said her little sister.
"I've got more things to worry about squirt!"
Hanna went to inspect herself and pulled down her tight yoga pants and (since she wasn't wearing any underwear) could see that her vagina wasn't what it was earlier. All her public hair was gone and it looked like a very small hole, even younger than a toddler's. Rebecca felt like crying, but she knew she had to get herself and her sister to a hospital.
Rebecca rushed to pull her pants back up and went to help Hanna put her's on. She got the princess underwear on when Jenny whispered, "Age Hanna's hips and butt 15 years and deage Rebecca's hips and butt 15 years"
Just as Rebecca was pulling up her sister's pants, she found them to be stuck. She pulled and pulled as her kid sister was screaming, but she stopped when she saw what was happening. Hanna's hips had exploded and her ass had filled out into a perfect heart shape butt that any woman would love to have. It looked very odd to see this on a four-year old's body.
"What's happening Becky?!" screamed Hanna.
"I..I...don't know..." Rebecca was just in shock and really couldn't get words out. She didn't even notice her once tight yoga pants had slipped down her legs and now her baby butt was exposed. Her little butt had a hard time holding her upperbody and forced Rebecca to fall down on it. It hurt and Rebecca started crying like a baby.
