"H-hello?" Jenny gasped into the phone. Her forehead was slick with sweat - she'd experienced so many orgasms in the past few moments that it felt like she was waking up from a long coma. Even now, she could feel the pleasurable sensations from her nipples sending shivers of pleasure down her spine.
"Jenny? Did you miss the bus again?" Bethany teased her on the phone.
"Y-yeah," Jenny said, trying to resist the urge to stroke her nipples some more. "I guess I did."
"You okay there girl? You sound kinda off."
"I-I'm fine. I...something weird...it's not important..."
"I can come give you a ride to school if you want!"
"I-I'm not sure...oh man...I'm not sure I should go to school today..."
"Are you sure you're alright?"
At that moment, a familiar tingling sensation began to spread through her chest. "Oh no!" Jenny squealed, dropping the phone. "Not again! Not bigger! Please! They're big enough already!" She moaned, feeling the growth pick up, and felt her already straining shirt grow even tighter, mashing against her sensitive nipples to the point of bringing her to orgasm once more. "F-fuck!" she gasped. "Too big...was that Kyle again or something else? Fuck!"
Bethany was listening to all of this on the phone. "Jenny?" she called into the phone. "Jenny??"
"My breasts...too big..."
"That's it...I'm coming over," Bethany said, hanging up. In her car a few blocks away, Bethany's face had gone red with a sudden onset of desire. There were two things she desired in the world, and two things that she assumed would never be within her grasp. The first was breast expansion - yeah, it was a bit of a niche genre, mostly dominated by men, but god, she loved browsing for images of girls whose tits grew out of control. And two - she had a massive crush on Jenny. Jenny was the sexist girl at school by far, but Bethany knew she could never act on it. Jenny was popular and hetero - trying to make a move on her would just get her kicked out of the popular club. But listening to Jenny's squealing on the phone...well. She had to investigate for herself.
