"Hello? Ally? Are you home?" called a girl's voice. Ally jolted and nearly fell into the tub in surprise. She clutched Kelly to her to keep her from slipping from her grip. Once Ally had recovered from the surprise, she cursed herself for being so forgetful. Her best friend Jenna was coming over to play today. The two girls had been planning on playing Disney Princess today. Ally should have remembered this before she had gotten into the tub, even if the shampoo didn't make her older. But then that gave her a thought. The blue shampoo made Ally into a full grown woman, it could easily do the same to Jenna. And Ally knew from personal experience that the changing process fell incredible.
She tied up her robe before wrapping Kelly in a towel and heading out of the bathroom. As she walked to the top of the stairs, she could see Jenna down at the front door. Considering Jenna was an Asian girl, it only made sense she dressed up like Fa Mulan for their playtime. Jenna looked up as Ally came down the stairs. She gaped in surprise at the beautiful woman holding a baby in her arms. "Who are you?" asked Jenna.
"Would you believe I'm Ally's aunt?" asked Ally in a teasing voice.
"Are you?" asked Jenna.
Ally chuckled and said, "No, I'm actually Ally and this is Kelly." She allowed her smaller friend to see her baby sister.
"But how did you get big and why is she a baby?" asked Jenna.
"Oh, Kelly brought home some magic shampoos," said Ally, "I got the one that makes you older, Kelly got too much of the one that makes you younger."
"Magic shampoo?" asked Jenna doubtfully.
"Yes, I can show you," said Ally before leading Jenna into her mother's bathroom. There was still a Jacuzzi full of blue suds, but Ally grabbed the shampoo bottle. "Just put it in your hair like this..." said Ally before squirting a little on Jenna's head. She lathered up Jenna's head a little, which would work better if it was wet. But eventually, Jenna felt a shudder and popped up a little in height.
"It works," said Jenna in amazement.
"Yeah, and if you keep it in your hair long enough, you'll be as big as me," said Ally, "I'd wait in the shower if I were you." With that, Ally walked out off the bathroom. Jenna felt another surge of growth, her dress starting to get a little tight on her. Eager to grow even more, she took off the dress, though it was a little harder as it was getting smaller on her. She went through two more growth spurts before it was off. She headed into the shower and got the water running. As she waited for the water to heat up, she felt the tingle of another spurt, this one causing her nipples to stick out. Jenna had a strong feeling what was about to happen next. She stepped into the shower and rinsed her off quickly before putting more shampoo into her hair.
Meanwhile, Ally was in the living room, taking care of Kelly. Kelly had no trouble latching onto Ally's other nipple. To her infant mind, her sister's milk was just as good as her mother's, not that she could tell the difference at this stage. Ally moaned in pleasure as Kelly nursed. It felt good when she was rubbing herself, but this brought a different kind of pleasure. She knew she couldn't keep Kelly as a baby for long, but she was enjoying breastfeeding too much right now.
Jenna was also learning the joy of nipple stimulation. As she grew older, her breasts became larger and more sensitive. It wasn't long before she was rubbing a nipple with one hand and finger her pussy with the other. "Oh, this feels so good," moaned Jenna as she went through her teenage years. Her aging mind was filled with fantasies of dreamy men pleasuring her. "A little more, a little more," she moaned huskily as her maturing reached its peak. Her pleasure peaked first, causing Jenna to let out a loud moan. She gasped for breath as she came off her orgasmic high. Then she remembered the shampoo would keep aging her until she washed it out. She quickly put her head under the stream of water and scrubbed the suds out. She wanted to get old, but not too old.
Ally eventually looked up when she heard footsteps approaching. She saw a beautiful young Asian woman walking towards her in her mom's spare bathrobe. The face was unmistakably Jenna's, framed by raven hair. Ally set Kelly aside and closed her robe up a bit more before standing up. "Wow, Jenna, you look great," said Ally as she walked towards her friend.
Jenna smiled and said, "I wish I could have gotten a little bigger though." Jenna was obviously shorter than Ally, almost by a head. And her breasts, though a C-cup, were easily overshadowed by Ally's giant rack.
"Trust me, you are a knockout," said Ally before she whispered, "If you want your boobs bigger, you can let Kelly suck on them. I got an extra cup from that."
"Er, no thanks," said Jenna, "So, what do you wanna do now?" Ally considered, there were quite a few options for the two grown women.
