Serving Your Sister: Ch.1

Prologue

Growing up, Molly had been a pretty  good sister. The two of you weren't very close, but you never fought too  much either. Sure, there was always teasing but you kept it  lighthearted and nothing beyond what would be considered normal between  siblings. You were just a year older than her, but even though you were  close in age you never really ran in the same friend groups. Not to  mention the difference between your personalities. An outsider might  describe you as a jock - you played for the soccer and basketball teams  and were fairly tall (6'1''). But the truth was, you weren't a meathead  like some of the other guys on the team. You were pretty interested in  science and didn't really enjoy going to parties or socializing much  outside of school.

Molly, on the other hand, would have killed to  be as attractive as you. She was always on the shorter side, only  5'2'', and unfortunately looked like she was still 12 years old when she  turned 18. She was flatchested and very scrawny. It was evidently  something she was very insecure of because you noticed whenever you were  out in public, she wore baggy sweaters. Unlike you, the introvert,  Molly wanted to be the center of attention. She envied the popular crowd  who partied every weekend and had lost their virginities at 15. Molly  wanted to be like them and she blamed most of it on her physical  appearance.

It was unusual that Molly was so underdeveloped. Your  mom, Angela, was 5'6'' and had C cup breasts. Your dad was 5'10 and had  a stocky build himself. Your parents had taken Molly to doctors  throughout her teenage years to see if her growth was stunted, but they  all gave the same reply: "Some girls get the short end of the genetic  lottery."

That's why when Molly's class took a field trip to a  local chemical factory her junior year (your senior year) of high  school, she was intrigued by the company's name: GrowTech. Molly never  had the best grades and was abysmal at STEM classes, but she understood  enough to realize that GrowTech made pills designed to help people,  well, grow bigger.

Now obviously, this was not released to  the general market, or it would be a billion dollar company. Right now  their products were in testing stages and primarily used on livestock.  Eventually, they would be used in third world countries to help  malnourished children. GrowTech never planned for an 18 year old girl to  steal a batch of their pills for her own personal use. Molly was  desperate, though. Desperate enough to steal experimental drugs if it  meant she'd have a chance at being beautiful. She didn't even really  know if they worked, she just heard the word "growth" and took her  chance.

All of this was unbeknownst to you, of course. It was  unbeknownst to everyone except Molly, who returned home from that class  field trip, giddy. She locked herself in her room and took her first  pills. She'd stolen two kinds: General Growth, which promised growth  throughout the body, as well as Breast Growth, designed to boost milk  production on dairy farms. Molly swallowed one of each, eager to see the  effects set in. And this is where our story begins, the story of a  growing sister and you, her brother.

Ch. 1

While most people relished Saturday  mornings as a chance to sleep in and relax, your parents saw it as the  perfect time for cleaning out the house. It was not uncommon for you to  be woken up by the sound of a vacuum cleaner outside your door or pots  and pans rattling in the kitchen sink downstairs. On this particular  Saturday, you tried to ignore the sounds of cleaning, but were called to  action by a knock at the door.

"Time to get up, Tim!" your mom called. "You know the drill."

You  grumbled and rolled out of bed. You opened the door and saw her  standing there, her head just below your shoulders. She handed you a  cleaning bottle and roll of paper towels.

"You can get started in the bathroom. I've asked Molly to do the hallway."

You  set to work cleaning the bathroom and heard Molly humming to herself in  the hall. All of a sudden there was a little knocking on the bathroom  door.

"What do you want?" you asked her.

"Just checking in," said Molly. She seemed like she knew something because she didn't usually act so mischievous.

"What? Did something happen?"

She  must have sensed your suspicion because she gave a coy smile and left  without another word. Honestly, sometimes she could be a bit weird. She  was probably just trying to push your buttons so you'd get upset and  wind up being forced to do her chores too.

That  afternoon, after the house cleaning was finally done, you were plopped  in front of the TV, watching a hockey game. Your parents had left the  house and weren't going to be back until Monday morning because it was  your mom's old college friend's 50th birthday. That meant it was just  you and Molly for the next two days. It wasn't uncommon for your parents  to leave the two of you at home, especially now that you were both old  enough to drive and take care of yourselves.

You noticed Molly's reflection in the TV as she came up behind you.

"Hi-ya," she said. You grunted in response. "What's for dinner?"

"Mom said we could order a pizza."

"Mmmm good. I'm starving!"

"Oh yeah? You're usually not too hungry."

"Guess  my appetite has grown today," she said laughing to herself a little.  You tore your eyes away from the game and looked at her. She wasn't  wearing her usually baggy t-shirts or sweatpants. Instead, she had on a  tank top and cutoffs.

It must have been a while since you saw  your sister in such tight clothing because her chest looked a little  bigger than you remembered it. She'd always been so underdeveloped that  she never even wore bras and she wasn't wearing one now, though it  looked like she could use it.

You must've looked a few seconds  too long because Molly clicked her tongue and when you looked at her  face, her eyes were locked on you. Oddly, though, she didn't seem too  mad. She went into the kitchen and poured herself a glass of water.

You  didn't pay any attention to this, but if you did, you would have seen  her tossing back two more of the GrowTech pills she'd stolen.

After  taking them, she came over to the couch and scrolled on her phone,  glancing at the TV now and then. Your team ended up losing and on that  note of frustration, you turned off the screen. Molly looked up.

"Pizza time?"

"Sure," you said. "How about a large pepperoni?"

"Make it two. And can you get the garlic bread bites too?"

You raised your eyebrows. "I don't know Mol, that's a lot."

"Just order it."

You  were surprised at the tone of her voice. It was oddly commanding for  someone who'd been so timid most of her life. You obliged and ordered  it, figuring you'd have the leftovers for lunch tomorrow.

When  the doorbell rang 30 minutes later, you went to the door while Molly  grabbed plates. She licked her lips and bounced up and down as you  brought the pizza in. Without waiting, she grabbed two slices and  started devouring them. It was a bit distracting seeing her eat that  fast. You'd never seen her that hungry and to be honest, it was a little  disconcerting.

"You ok?"  "Mmmph.. never... mph... better!" she managed to say between bites.

You  shrugged and chalked it up to her not eating much throughout the day.  As Molly went in for round two, you noticed that her tank top was riding  up a bit, revealing her taut stomach. That was weird because earlier in  the day, it had seemed to fit her fine. Not only that, but her tiny, but  present, boobs seemed bigger too. They were about the size of  clementines, at least an A cup of B cup. That didn't seem right -- she'd  had no boobs to speak of a week ago!

Thankfully, Molly didn't  catch you staring at her chest this time and she seemed oblivious to her  recent development. She grabbed her 5th and 6th slices and went  upstairs to her room to finish them. She also brought the box of  breadsticks with her too. At last it clicked -- she was having a growth  spurt! The increased appetite, the clothes not fitting, it all made  sense now. You felt happy for your little sister, knowing how long she'd  waited to go through puberty. Maybe this would help boost her  self-esteem and help her feel more like a teenager.

Little did  you know that this wasn't a natural growth spurt. It was something  brought on by Molly herself. Something she was fascinated by and would  soon be addicted to. If you had known at the time what was happening,  you might have had a chance to stop it. To avoid the irreversible  changes that would come. But you did not know. Nobody knew, not even  Molly herself...
