Bobby stopped, and decided to have only Mary grow older, at least for now. With that he took a deep breath and said "I wish Mary Anderson was twenty years older."
Mary though unaware of Bobby's wish, felt a weird sensation suddenly sweep over her body. Mary couldn't help but let out a small gasp as her tiny body shook a bit. "Are you okay Mary?" Johnny asked as he saw the odd little twitch his patient made. "I feel funny..." Mary replied. Johnny then smiled as he now proudly said "Don't worry, I'm a doctor!".
But just as Johnny had finished saying that, Mary lets out another gasp, this time her height shot up as well. Johnny eyes widen as now Mary was staring back at him eye-to-eye. Mary a little frighten by her own growth quickly wrapped her arms around her playmate as she then quickly sprouted a couple more inches higher. Johnny quickly felt as his feet leaving the ground as Mary was beginning to grow so fast and tall, that now she was lifting Johnny up with her.
Mary quickly approached the age of eight, making her twice as old as Johnny, and also twice as tall with no sign of stopping. . Mary hair has gotten darker and thicker as she grew, making her long straight blonde hair burst out from the pigtail ties, and fall down. Her ill fitting Dora the Explora t-shirt displayed a midriff as it also continues to stretch across her widening chest. Mary soon pass the double digit, and signs of puberty began to emerge. Johnny having his face still pressed against Mary's chest, couldn't help but feel as two bumps began to push out. Suddenly Mary's budding breast swelled intensely as she let out a moan, her shirt ripped and fell to the ground from the pressure, and again Mary's breast swelled with great force making them quite large for her current age.
Mary's body also began to curve out as she continue through her teenage years. Her hips widen as her legs lengthen. The tiny skirt she wore could no longer even hide half of her round firm ass as it continue to push out, causing her training pants to split as they fell to the ground.
Mary let out another moan, which was now a deep low sexy moan that match her growing figure. Mary's breast continued to expanded explosively over the ages, making them massive, as little Johnny knew all-to-well by having his face squeeze into her deepening cleavage. Mary 's hips flared immensely, causing the skirt that was built to stretch, snap across her child bearing hips leaving this woman in the nude. Mary still pressing Johnny against her body, thrust her massive breast out, as she pouted her wide heart-shaped ass that had shapely long legs attached to them.
Bobby who was witnessing the end of Mary's growth couldn't believe his eyes as his mouth gape open. He knew that Mary would had probably grew up to be hot, but he would had never expected her to become this hot. Her face had become completely flawless and gorgeous, her long sandy blonde hair naturally shimmered in the light as they travel down her mid-back. Her breast were enormous, but firm and round, even her nipples were perfect in space and size. Her waist was thin, and her stomach had a slight impression of abs. Her hips was so wide that giving birth would be no issue, not to mention her ass was so round and tight that it demanded attention, only to have those long elegant legs distract you.
Forget being a dancer Bobby thought, Mary was fated to grow up to become the supermodel of her age, and to be in the mind of every teenage boy and men that has caught sight of her beauty. Bobby couldn't help but gritted his teeth in jealously at Johnny. Mary still held him tight against her bosom, but he was still too young to understand how lucky he was to have his face planted against her hefty breast as Mary heaved, catching her breath after the massive growth spurt, causing Johnny's little head to rise up and down with her tits.
Mary finally calming down took a look down at her body, only to let out another gasp. "Oh my god! I grew up!" she said, releasing one of her hand to put towards her mouth, for now she even was strong enough to hold Johnny with one arm after instinctively positioning it downwards, holding Johnny like a baby. "But... that's not all... I also feel... smarter?" Mary continued as she rose her hand to her head, still feeling a light sensation from all the information that seemed to pumped inside her brain. It appeared that Bobby did not only just make Mary twenty years older physically, but mentally as well.
"I guess this ring is the really deal after all" Bobby smiled looking at the now naked 23-year-old curvaceous woman standing in the middle of the living room, who just early was a tiny 3-years-old girl playing doctor with her friend.
Bobby then wondered what to do next, he then decided to...
