Jeff grabbed the Chronivac and brought back up Emily and Karen's stats. He raised their ages to 16 and made this oblivious to anyone but himself. Looking at them, he noticed them being somewhat hot. They had large hips and nice asses, with smooth, shapely legs. Their faces were sexy, yet innocent at the same time. The only problem was Emily's flat chest. According to the Chronivac, she had an almost nonexistent bust. By comparison, Karen's was a nice D cup. He raised Em's up to what's normally a little over a double-C cup. Modest, he thought. Next, he changed their dull hair. Karen was a short-haired redhead and Emily was a long-haired brunette. He changed Em's to a luxurious and shiny light brown. Karen's stayed the same length, he just made it look healthier. He called his younger siblings into his room to see the changes first hand.
"Karen! EMILY! COME IN HERE, I WANT TO SHOW YOU SOMETHING!" Jeff called as he stepped out from his room. The tiny fraternal twins walked into the room and sat down on his bed. "Yeah, big brother?" said Emily, eating a cookie she got in the kitchen. Karen was eating one too. "Just sit perfectly still for a second...". Jeff pressed the "Begin Transformation" button on the Chronivac.
After a second, the twins got taller and began to fill out. Their hips got larger and their clothes seemed to grow with them. Their asses got bigger and it made them go up a bit on the bed. He noticed their waist shrink into an hourglass shape as their baby fat traveled upwards to their breasts. Their arms got slightly bigger as their legs gained a more womanly shape. The changes got to their face and their lips got fuller and turned a juicy red. Their cheeks got a slight pink blush and their eyelids turned a deep purple. 'Other than the hair', thought Jeff, 'they look the same...'
Jeff saw his work finish itself, and a confirmation message appeared on the Chronivac. His sisters regained consciousness and began looking around. Karen noticed what she was eating a spit it out in the garbage can. "Ew..." she said, wiping her tongue, "chocolate! So many carbs!" Emily laughed as she finished her cookie. "Relax, Kare...it's low carb!" Karen shot a dirty look at her sister and walked out of the room. Emily wiped her mouth off with a Kleenex from a box on Jeff's nightstand. "Hey, Jeff. Kare and I are going to the mall in a few. Wanna come?" Jeff nodded and looked down at his clothes. "Sure, sis. But lemme change; this outfit is dirty." Emily smiled. "'Kay. We'll be watching Laguna Beach. Let us know when you're ready."
She left the room and closed the door behind her. Jeff chuckled as he grabbed the portable emitter from the Chronivac box. "I wonder what to do at the mall...?"
