Bobby then took a deep breath in relief as he heard Jennifer's mom leave the room.
"Time to fix my age" Bobby mumble to himself, and with that he concentrated on himself, wishing that he was 6 years older.
Bobby body began to stretch again, return him to his former size. After he finished growing, he made sure to clothe was property on before heading home.
Later that day, Bobby got the call he was expecting from Jennifer's mother, and once again return to her house.
"So glad that you can make it today." Her mother greeted him at the door, the pair of girls were gripping her legs. Bobby couldn't help but notice the devious smiles on their little faces. "Her friend Ashley is also staying the night over, I hope they won't be too much trouble for you."
"No problem, I think tonight is going to be rather fun" Bobby smiled, the girls giggled to his response.
"Okay Jennifer, mommy has to go now" Jennifer's mother said as she bent her knees, giving her daughter a kiss on the cheek.
"Bye mommy!" Jennifer waved as she exit the door.
As the door slammed closed, the girls let out a sigh.
"Finally" Jennifer grunted. "Here Bobby wait a second, Ashley and I are going to find something more loose to wear, we'll be right back." She said as they skittered off to her mother's room.
Jennifer's brother that heard the change of tone in his little sister voice, couldn't help but notice how strange it was.
The girls returned moments later, now with an over-sized t-shirt hanging down their bodies, reaching to their knees, and her mother running shorts, for Bobby can see the string that was dangling on the ground for being pulled so much just so it can fit their narrow hips.
"Hey Shorty, why are you wearing mom's clothes?" Her brother ask, walking up to his little sister and looking down at her.
"Okay Bobby we're ready." Ignored Jennifer, "Make us the same age as you again."
Jennifer's brother hearing his, thought it nothing more than just a game perhaps, but then he heard Bobby said to himself, "I wish Jennifer and Ashley were 11 years older."
As soon as he said those words, he notice something strange happening to the girls, they were getting taller! Jennifer's brother looked in horror as he saw his once tiny sister caught up to his height, only to meet it for a brief moment, only to just rise above it. Her brother now had to look up in order to see the face of his 'little' sister. The girls were now almost 12 again as they felt their chest tingle, as a mound pushed out again.
"Here they come" Ashley gasped as she put her hands on her budding breast again. Jennifer also smiled as she put her hands on her chest, feeling them swell under her palms.
The girls clothes started to look natural on their growing bodies, as the t-shirt didn't look so over-sized anymore. The string of the running short retracted back as their hips flared out and it was beginning to tighten across their thickening thighs and pouting butts.
Jennifer's brother watch in horror as he saw his little sister now tower over him, all he can see when he looked up at his sister were the two mounds of her swelling breast that blocked her face. Her legs were now getting long and shapely, and her ass wider and firm with her expanding hips.
The girls finally reached the age of 16 again, their large perky breast pushed again the fabric of the t-shirt, as Bobby can see their hard nipples poking against it.
"It feels so good to be older again" Ashley moaned, as her hands traveled down her curvaceous body, cupping her firm wide ass cheeks with her hands.
Jennifer just smiled with her hands on her hips, as she looked down at her frighten brother. "Hey short stuff" she giggled.
"H-how did you get so much bigger Jennifer?" her brother said as he voice quivered.
"Ask Bobby" she giggled, as both the girls walked over to Bobby, as he wrapped his arm around both their slim waist. Jennifer brother couldn't believe what he was seeing, the little girls that was once his sister, and her friend, were now both provocative teenagers.
Jennifer smiled as her hand travel down Bobby chest, then she thought of something and said, "Hey Bobby, we should..."
