Showing Lauren

    by: LGV Author IconMail Icon
Those bumps, as tiny as they were, were a monumental for the flat-chest fourteen year old. It was the first step towards finally getting the feminine bust she deserved. Both her mother and Lauren had ample bosoms, leaving Megan as the odd girl out and the subject of Lauren's occasional ridicule.

As siblings, the girls did love each other, but a certain degree of rivalry had developed when Megan hit puberty. It was an interesting arrangement: Megan, jealous of her sister's curvy bust, took shots at Lauren's belly to boost her own confidence. Lauren, envious of Megan's nearly perfect shaped backside, took pleasure in pointing out her extraordinarily flat chest. A vicious cycle.

Now though, it was Megan's time to shine. Eager to shove her soon-to-develop breasts in Lauren's face, she slipped into a pair of loose fitting pajamas and exited the room, making her way back towards the living room. There she found her sister, reclining on the old sofa, watching some by-the-numbers prime-time medical drama with a mug of who-knew-what locked in her hand. With a pep in her step, the confident girl strolled between the T.V. and her older sister, positively pissing her off.

"What the hell are you doing?" Lauren asked as she placed the mug on the table. "I'm trying to watch a show here, Meg."

"Don't worry sis, it'll only take a second," Megan said as her eyes darted around. "Say, do you know where Justin is?"

"He's still in his room playing nerdy video games, why?"

"Oh, good. Then I guess I won't have to worry about him seeing this..."

As Meg trailed off, her hands grasped the base of her pajama shirt and pulled it up, revealing her pale, nude chest. Lauren, not noticing the small bumps that had formed, simply rolled her eyes.

"Training for Girls Gone Wild, are ya? You know, they only accept busty chicks for that." she joked.

"Hah, very funny. Look closer. There are bumps. My boobs are growing!"

Lauren, examining Megan's chest once more, was genuinely surprised to find that her sister wasn't lying. The whole family had assumed that, barring implants, she'd always be as flat as an ironing board. This sudden change left Lauren with mixed feelings. She was indeed happy the her baby sister's wish was coming true, but she also felt a twinge of jealousy. The last thing she wanted was Megan to outgrow her and dethrone her as the sexiest girl in the family.

"Well, it was about time Baby Megan hit puberty. Congrats, sis."

Lauren, so lost in her selfish thoughts, hadn't noticed the contorted look of shock that had grown on her sister's face.
Why was she shocked?
