A Girl's Growth Spurt Overload

The three girls went downstairs to the Kitchen and began to pour things together, each of the three agreed to start with milk, as they all knew it helped with growing. They didn't know the gallon of milk in the refrigerator had extremely high levels of human-growth-hormone in it and the things they were adding to it would multiply the effect.

Lindsay took the container and poured 3 cups. Lily and Kiki both took a cup and the three were standing near each other in a circle. Each took a long drink and winced at how foul it tasted and deeply hoped it would not be a waste. Kiki drank again first and seemed to do so with conviction. Lily took a sip and shuddered while Lindsay drank some, doubtful it would work,but hoping none the less. There was still a great deal of the drink left and the three waited to see if anything would happen.

Kiki put her hands on the sides of her tummy and it made loud noises as did Lily's and Lindsay's. Kiki moaned and crouched down while Lily was staring at her hands. Lindsay could feel a strong tingle all over her body and felt very dizzy. Lily kept staring at her hands and Kiki began to swell out slowly. She was 3'11 originally and was slowly getting bigger. She didn't know it but was now 4'2 and getting larger slowly. She was very aware of her butt rubbing against her backside and could feel her panties wedgie as she slowly became thicker. Lily was 4'1 before and while Kiki was expanding she could feel her legs getting longer as did her arms. She was near 4'6 and excited at how things were. "It really worked!" Lily shouted. Kiki looked up and could see 4'7 Lily expanding outward. Lindsay was overjoyed at what was happening. It was her dream come true and she was getting to share it with a new friend and her sister. "I feel so strange." Lindsay said in a dreamlike way. She was 5'0 and looking down at the top of Lily's head. The three girls were each getting larger, Kiki's shorts began to make strained noises as her very round bottom grew. Kiki bit her upper lip as she could feel her nipples swelling. She started to paw at herself while Lily and Lindsay were each busy with their own experience.

Lily felt her face burning red but was very excited at what had happened. She felt a very strong burning in her nipples and looked down to see her breasts budding. Her tiny buds were growing in circumference and becoming a darker pink color. Now over 5'1 It felt like hot tingling and like something was pushing into her nipples making them swell almost throbbing. "Oh wow, I didn't expect to get boobs." Lily watched her nipples continue to swell as they formed mounds that continue to puff out into cone-like swells of flesh. Lily could feel her white panties ridding up her butt and it started to dig into her private area. She was close to Lindsay and felt her put her dark tan arm on her shoulder to steady herself.

Lindsay was smiling as she watched what happened to Kiki and Lily knowing that she too would be undergoing similar changes. Her nipples continue to swell out like Lily's and she noticed the mounds began to sag with fullness, forming two tear-drop like pointy spheres of flesh and her breasts continue to blossom. Lindsay's training bra began to feel painful on her as it dug into the middle of her shoulders very perky now B cup breasts were causing the straps to dig into her back pinching her tightly. She could feel her panties and shorts creak as her thighs got wider. "Oh wow I am getting huge!" Lindsay said and admired her now thick legs and butt.

Kiki was almost 4'5 and much more pudgy than she had been before. Her breasts were very full C cups growing into the D range and she felt her tummy was very round and full compared to Lindsay who had very thick hips and a very round butt but an almost flat tummy. Lily was much more thin, petite and somewhat lanky. Kiki felt like the effects were weaker and reached to grab the jug of milk.

She drank deeply from it to the surprise of Lindsay and Lily who were so engrossed in the changes going on in their bodies they didn't even think to go for more so soon. Kiki shuddered and drank nearly half of the container in several large and somewhat strained gulps. Lily then looked at Lindsay who noticed and took the milk from a panting Kiki, Kiki started to giggle from how happy she was at what was happening. She laid down on the floor now almost 4'7. She could feel a very tight pinching from the button on the waistband of her jean shorts and put her index fingers in the belt loops and pulled, forcing the button to fly off. As the zipper slid down and her shorts parted Lindsay and Lily looked down to see Kiki's light pink panties under the tight shorts. Lily looked at Lindsay and her eyes went wide as she saw Lindsay was drinking down the rest of the milk quickly. Lily was ok with how things were and secretly hoped both of the dark skinned sisters would grow much larger than her, maybe even big enough to carry her like a baby. Lily was a deep shade of red in her cheeks and she couldn't take how powerful the waves of pleasure coming from her were. She was breathing very shallow breaths trying not to touch the very sensitive skin around her nipples and pussy. over 5'3 It didn't help that her panties were digging deeper into her and making her feel very awkward. Kiki's breasts could be seen clearly outlined in the light pink t-shirt that was slowly getting tighter around her, it dug into her shoulders and she was thankful she wasn't wearing a bra. Kiki could feel her nipples poking out from under her shirt and it felt amazing.

Lindsay was creeping past 5'4 while her rump and thighs puffed out as well. She could see her already very tight shorts unbutton on their own and she felt a pressure from her torso quickly fade as she could feel like her bones and skin were stretching and pulling outward. Lindsay let out a shrill squeak as she felt her bra strap snap on her back and her breasts spilled out. Her shirt was keeping her bra on her even though it was not holding up the very full B cup breasts Lindsay was adjusting her back to support. She instinctively rolled her eyes back as the tight fabric of her bra rubbed her very pointy tits. Lindsay didn't care that Kiki was staring up at her from down under her feet and looked down at her from behind her new endowments. Kiki was still giggling slowing and stretching out, her growth had picked up and was almost twice as powerful as Lily or Lindsay, Nether of the girls had the perspective to realize how much faster Kiki was expanding but her very plump body was slowly starting to rise up from the floor as she grew outwards. Kiki was slowly catching up in height to Lindsay who didn't notice as she was trying to fight back her body exploding in tingling feelings coming from her breasts and inner-thighs.

Lindsay felt like her vagina was getting sweaty and damp, like she was going to pee but instead it was just moist and very sensitive to the touch. Lindsay let out a gasp as Lily groped at Lindsay's very tight shorts. Lindsay could feel the legs of her shorts tearing and the gentle touch of Lily's hand on her. Lily moved in and kissed Lindsay on the lips and Lindsay put her hand on Lily's right breast. Lily was already bright red but she couldn't help pushing forward and letting her tongue slip into Lindsay's mouth. Lindsay moaned softly and her eyes fluttered as she felt Lily kneed at her privates. Kiki was staring up at the two of them and no one noticed Kiki was slowly growing taller than ether Lily or Lindsay. Kiki leaned hard into her shorts and could feel her rump tearing through the stitching on the sides of the shorts. Her very thick legs tore the shorts into two halves. Kiki removed the front tatters and saw her light pink panties were very wet around her vagina.

Kiki stuck a hand down the very strained waistband of her panties and could feel the slick wetness on her labia. Kiki let her fingers dance up and down on the fold between her legs. Her fingers made her feel extremely good and she didn't mind they felt sort of slimy from herself. Lindsay noticed Kiki from the corner of her eyes and was not expecting to see Kiki in such a position. Kiki was now almost 2 inches taller than her sister as Lindsay was 5'6 and Kiki was 5'8 her growth still a constant. Lily was slowly running her foot across Kiki's torso, and she could see Kiki's pussy clearly from now wet the under-area of her light pink panties were.

As this was going on Kiki's panties began to tear, and almost in unison the waistband of Lily's white panties snapped and Lindsay's shorts burst open, revealing her very light blue panties. Kiki continued to swell out and started to rub her right breast with her left and and then yelped as Lily put her foot down on Kiki's right hand pressing it very strongly into her very slick pussy. Lily was now 5'6 while Lindsay was 6'0 and Kiki was 6'5. Lindsay slide her hand down and lifted Lily's skirt, while sliding her hand under the waistband of her panties. The three of them seemed to climax almost in unison and were deeply glad no one else was around to hear the noise they were making. Lily was 5'7 and felt her legs giving out, she let her self go and her butt fell ontop of Kiki's stomach as she was moaning loudly in pleasure. Lindsay was next to fall and landed next to Lily on Kiki's chest. It was at this point they noticed how much larger Kiki was than ether of them.

"Wow Kiki, if this keeps up your going to be big enough to be a mommy." Lily said while still breathing softly from what had happened. She was 5'7 and a half inches while Kiki was 6'11 and Lindsay was 6'1. Kiki felt like the growing was still going strong and hoped they would find a way to make even more of the potion they made.

At this point Lily was 5'8, Lindsay was 6'3 and Kiki was creeping past 7 feet tall at a steady albeit stunted speed.
