Part 1:
Every woman in Ellie's family was absolutely gorgeous - each one more fantastically beautiful than the last. Everyone assumed her mother was a trophy wife with a hearty fund for plastic surgery, and even her grandmother's curves attracted men a fraction of her age.
Shortly after her 18th birthday, Ellie already looked like a porn star herself - huge, round, full breasts, slim waist, and flared out hips. Every time her grandmother saw her, she seemed more and more concerned.
"You should not let her wear such things," she cautioned Ellie's mother, Stephanie. Ellie was wearing a simple t-shirt and jeans - nothing too flashy, but still enough to make anyone weak in the knees with her figure.
"That's how girls her age dress," Stephanie responded. "She wouldn't fit in if I made her cover up all the time."
"Men these days don't control themselves," the older woman continued to push the issue. "She is already bigger than either of us were at that age, and she grows more and more each time I see her. These things escalate quickly - the bigger she gets, the more attention she will attract."
"Oh, Ma, don't start with this again," Stephanie rolled her eyes.
"It's our family curse!" Betty, the matriarch demanded. "Everyone is full of themselves, but we have to show it. And you know what happens when you get too full!"
"There's no such thing," Stephanie argued. "It's just genetics! Every woman in our family has been an early - and late - bloomer, and we've all grown quickly. Sure, maybe Ellen got it a bit stronger than we did, but anyone would kill to look like she does."
"Let's just hope she doesn't know it herself. Even you were too full of pride, and look where it got you - " she poked at her daughter's melon-sized breasts. "Tell me you never thought you were growing too quickly or felt too full?"
Stephanie bit her lip. In truth, she had always done her best to downplay her daughter's figure, but never wanted to push it on her enough to drive her away - they simply found other family activities to avoid situations where Ellie would attract attention. The family had stuck to living in small towns, and growth spurts did tend to strangely coincide with trips to the city. Stephanie could recall a number of her own growth spurts over the years, and even now she found herself needing to resize her tops every once in a while.
Ellie was aware of the "Family Curse" as well - and was about to test it. Unbeknownst to her mother, she had been invited to her first pool party of the summer after graduating, and snuck off to find the skimpiest bikini she could bring herself to wear.
Sure enough, even with only a handful of boys at the party, Ellie could feel her bust swelling slightly the whole time. She, and some of her friends, posted pictures online, and as she watched the view counter tick up, her breasts quickly surpassed the size of her mother's overnight.
Ellie was hooked. Revelling in her new figure, she posted more pictures on her account and signed up for more social media sites. She had joked about the stories of her family curse in the past, and she often alluded to it as she continued to watch her figure develop.
"You guys thinking about my legs? Not sure how I got a runner's gap from sitting by the pool," she asked, posting a picture of her round, bikini-clad bottom with an incredibly alluring gap between her thighs. The next day she was sure that her hips were a bit wider, her cheeks a bit more round, yet better defined.
"Feeling XXX-tra busty today," she posted a picture of herself stretching out a tiny, triangle-cup string bikini. "Is somebody wanking?
"
Was it just a coincidence that she started another growth spurt as soon as she posted the picture to her growing group of followers? Over the next three hours she had a tape measure glued to her hands as she felt her bustline growing an inch per hour.
Finally she couldn't take it any more and posted another picture of her bulging breasts making the tiny, strappy top almost obscene.
"Jeez guys, I'm getting huge here - you've got to be chaffing yourselves by now!" she teased.
Ellie didn't realize that the pictures were quickly picked up by a larger site and posted across the front page. By the time the morning came, Ellie's breasts had each swelled up another inch in diameter, and her social media accounts had tripled the number of followers. The feeling of growing so quickly had kept Ellie up, driving her wild, but she moaned slightly as she messaged her bloated, swollen breasts the next morning. Her rapid growth had left her feeling incredibly full, her skin a bit tight. Still, it kept her breasts perfectly round and high, expanding evenly outward from her otherwise slender torso.
They looked so good Ellie had to post another picture, even as she wondered if it really was a good idea.
Her growth had snapped the straps of her nightie, but her enormously full breasts has no problem holding it up as it stretched tight across them.
"Couldn't rest last night because I was growing so much - I take it none of you did either? Feeling a bit tight from growing so fast. Do you think that's what's keeping my breasts so perky?"
The response was almost explosive. Ellie had planned a day at the beach with a few of her friends, but she was kicked off after she couldn't stay in her swim top, and then tore out of another t-shirt as she bulged out several more inches.
She rushed home to check her accounts and found that her number of followers had doubled again.
The comments were becoming much more lewd as well, with graphic descriptions of wanting to tit-fuck her, calling her fake or a slut, cautioning that she was overfilling her implants, and even some encouraging her to keep stretching herself until she burst.
Ellie responded with a selfie and a somewhat desperate plea. Her eyes were wide, her brows askew, and she bit her lip worriedly as she pushed her bulging cleavage up to her chin.
"Okay... So my boobs have grown from the size of volley balls to the size of basketballs since this morning. I'm still not quite sold on this whole "curse" thing, but just for fun, could you all try
not spankin' it to me for a bit? I don't know how much more I can take I feel sooo full and tight!"
Of course the post had the opposite effect - even those who believed her couldn't not be turned on by the thought. Ellie's breasts began to bloat and bulge at such an alarming rate that she quickly blocked new people from following her accounts, and took down many of her most provocative posts. It took several days for her rate of growth to settle, but even from that point on, the feeling of growing was almost constant.
