The coin landed on heads: it was time to pay some neighborhood pranksters a visit...
The Morrison house was always quiet this time: Mauricia was heading her restaurant's kitchen, George was at work, it was the perfect time for some pay back.
"I can see the little shits right from their living room window..." Willa grinned.
"Get down, somebody's coming!" Flynne said as she pulled her friend to the ground.
A young woman was walking up to the door, and she was a beauty.
Rich tan skin, a nice round rump and shapely thighs hugged by torn neon leggings, a halter top to sling her D cup breasts in, and some eletric blue and pink hair the amazons weren't too sure about.
She rang the doorbell as the boys answered the door.
****************************************************************
Ryan and Maurice Morrison were your average 14 year old pranksters.
They got bored easy and always found trouble.
They weren't expecting to answer the door to the person standing there.
"Hey little bros, miss me?" the woman asked as she swayed her hips back and forth.
It was their sister Tiffany, except she looked like she'd been under the knife a few dozen times since they last saw eachother.
"Tiff, is that you?" Maurice asked, "Where were you?"
"And what did Tabby want?" Ryan asked.
"It was nothin' major dudes... just found somethin' awesome I wanted to show you." Tiff smiled as she put her cleavage out in front of their faces.
Something was way off: Tiffany never talked like that or showed them anything.
"Come on. Like, I won't bite." Tiffany smiled, pressing her chest up against them.
"Uhhhhh..." Ryan blushed.
"We have to go call mo-" Maurice started.
Tiffany immediately slipped off her top and jammed them against her breasts.
The boys struggled and let out muffled cries as their sister smothered them.
"Just try it: you'll be so hawt when it's over..." Tiffany said.
They squirmed a little bit longer, slowly but surely giving in to the chonivac's influence.
Tiffany moaned as the warmth flowed from her teets to her bros.
They moaned back, their lips plumped up as they started growing as tall as their sister with her heels off.
She smiled as their skin smoothed out and their waists shrunk down, caressing their new, big, bold hips.
The infector smiled with pride as her sisters' tits blossomed forth, hittting size DD and ripping their shirts open; the three looked like triplets from the neck down.
She jammed her fingers into their warm, wet pussies to push them along, hearing their moans as their torn clothes melted and twisted, forming two tube tops and skirts so micro they looked like napkins.
The 19 year old girls released their suction on their hottie sis' nips and giggled as their hair grew long and blonde.
"Omigawd sis, you were like, sooooo right." Rihanna drooled as she groped herself in a mirror.
"Totally sis, like, thank you." Mauricia Jr purred as she rubbed her ass.
"Not a problem, girls." Tiffany smiled as she pulled them in for a three way kiss.
Willa and Flynne sat in the bushes completely flustered as the sisters began spanking and titty sucking eachother.
"What just happened?" Willa asked.
"Things just got interesting." Flynne replied.
