Lindsey couldn't even stammer out a reply to Kat's rhetorical question. Watching that waitress inflate like a balloon had removed all doubt in her mind. Now she was focused the possibilities. Being Kat's best friend, she too shared a similar personality; one centered on petty revenge and disregard for others. Lindsey was already formulating plans to get back at others. Some even involving those at the restaurant. There was one thing though that kept bugging her. It was a desire she could not keep down, forcing its way to the forefront of her thoughts like an unwanted pest. Compared to her other machinations, it was rather normal: she'd wanted bigger breasts. Since the beginning of puberty Lindsey had to watch as her friend's chests bounded outwards as she was forced to deal with one as flat as an ironing board. Even presently she felt the pain of inferiority when changing with the bustier girls in the locker rooms. But now that was about to change, if Kat'd agree.
"Yeah, it really does girl. I thought you were joking, but I guess I can't deny it now" she broke the silence with. Seizing the opportunity to massage Kat's ego, Lindsey leaned forward on the table to close the distance between the two. From there she reached her hand out and began stroking Kat's now flat stomach. "So, I take it this is where Dan is?"
"Well actually" Kat began "When I came in my belly was still bulging a little, so now that its flat he's probably somewhere in my intestines. Or what's left of him, that is"
Lindsey let out a short giggle at Kat's last statement. "Well, goodbye to Danny-boy then! On a more serious note though, knowing you Kat, you're probably just dying to mess with more people. But, um, could I ask a favor first?" Kat could only raise an eyebrow in response before she started talking again. "I was wondering if, you know, you could make me a little...bustier? Just up to a b-cup or something, if its not too much trouble?"
A smile crawled its way across Kat's face. This was the perfect opportunity to test out a breast growth spell and she had a fully willing guinea pig. This was a rare opportunity and she was happy to help, though she'd certainly grow them far larger than simple b-cups. It took only a few moments to locate the spell in her book. Like the others, she read off an incantation while pointing her wand at her subject. A gray beam of light soon bolted out of the wand a struck Lindsey in the chest to signal the start.
It was hard for Kat to notice the growth initially, mainly due to the thick blue sweatshirt Lindsey was wearing. She'd even gotten worried that the spell had misfired or gone wrong. Thankfully her fears were allayed when Lindsey grasped at a strong tingling feeling on her chest. Kat watched as the previously flat sweatshirt began to expand outwards as more breast tissue was forming. Like the waitress's inflation, Lindsey's chest ballooned outwards in a slow, dramatic fashion. Kat mused that due to Lindsey's signals to stop that they must have been around b-cups.
Sadly for her, that was just the beginning. They continued their growth unabated, growing rounder and fuller with each passing second. Eventually the expanding mounds had reached the point that the lettering on the tight sweatshirt had started to stretch and the fabric was beginning to chafe her burgeoning bosom. In response, Lindsey quickly ripped it off to give herself more breathing room. This left her with only a pure white tank top with(thankfully)no bra. As her tits pushed past the c-cup range that too push against the limits of the tank-top. It had been designed for a-cups so now it was struggling to contain its cargo. Unable to push forward, the new mass began to overflow upwards, creating a deep cleavage that Kat couldn't help but stare at. Yet it still wasn't finish. More and more meat was added until finally they stopped at a large D-cup, but not before causing a small rip down the center. While it was embarrassing, Lindsey appreciated the pressure it removed and it still covered the goods, so she was mostly okay with it.
Shocked at just how big she'd grown, Lindsey began to poke and prod her new bust while Kat sat back with a satisfied grin. She was tempted to grope them herself, but decided to wait until later. Instead, she pondered her next move
