Jen dashed out of her room into the hall. She didn't want to miss the bus. She darted down the stairs a flew through the stairway door into the downstairs hall. And ran right into her older sister Kate.
Kate was twenty-five and in college. If Jen was pretty, then Kate was a bombshell. Perfect tits, tight ass, a figure to die for that wasn't too skinny and had curves in all the right places. Her eyes were the most beautiful shade of vibrant blue and her black hair always had that most gorgeous shine to it. Jen hoped that when she was all done growing, she'd be a bombshell just like Kate.
"Wow Jen, you're sure in a hurry. Going topless today? That's a bold move."
Kate and Jen both stood up. Jen wasn't looking forward to what would come next. First of all, she'd be affecting her sister's perfect figure. Second, and more important in Jen's mind, she was going to miss the bus.
"Transform or Dare?" Jen asked once both were standing.
"Transform?" Kate replied, a bit confused by both the question and her own answer.
"Okay, I'm going to roll a die and we'll go from there."
Jen rolled the die which turned up on a 6.
"Okay Kate, time for your transform. You're going grow an additional four breasts that will grow in as two pairs below your current ones. What cup size are you?"
"Double Ds, why?"
"Okay, then your four breasts will also be Double Ds. Don't worry, all your current clothes will change to fit. However, you will have to go topless for the rest of the day. You'll also start producing milk and will keep producing for a full week. After that, you'll be able to turn milk production on and off at will. Finally, you'll find breastfeeding other people to be a major turn-on."
Kate immediately removed her shirt and bra as her new breasts started growing in. It took about ten minutes because of the number of new breasts and the size that they had to reach. When they finished, Kate looked down at her chest. "Wow. That was, interesting."
Looking back over Jen, Kate seemed to notice Jen extra pair of breasts for the first time. "So you only rolled a four huh?"
"Yeah." Jen looked out the window and saw the bus pulling away from the curb. "Shit, I missed the bus."
"I'll drive you," Kate offered, "then you can explain what happened."
"Thanks."
In the car, a unimpressive Ford Taurus, Kate backed out of the driveway. "So how you, and then me, get stuck with multiple boobs and a breastfeeding fetish?"
"Kyle Perkins," Jen answered.
"And who's he?"
Jen explained, telling Kate about the pantsing incident and then the phone call that morning.
"So, every woman or girl who talks to you gets multiple boobs?" Kate asked as they pulled up to the school.
"Yup. Part of me isn't looking forward to it, but part of me is glad I won't be the only multi-boobed freak in town."
"Do you think it's now genetic and passed down to our kids?"
"Don't know." Jen grabbed her backpack and opened the car door. "Got to go."
"Call me after school," Kate said. "We can talk more about this and maybe have a breastfeeding session."
"Sounds good," Jen called back and headed into school.
