Give in to desire

"Uh.. uhm...", Jack stuttered.

The world seemed to move in slow motion. His lobotomized stammering continued as he gawped at the sight before him, but his brain was already tuning himself out entirely. His mom looked at him with a concerned expression, still dressed in her maroon gown and sleepwear. The Snapster filter had instantly ballooned her breasts up to stacked proportions, forcing the neck of her gown and loose top wide open and exposing a beautiful valley of cleavage. The shirt was being stretched to its limit. The fabric had thinned under the strain of his mom's new endowments, just barely revealing her nipples. In his pants, Jack felt his recently upgraded cock stir.

By some miracle, Sharon hadn't yet noticed that anything was different. Jack hypothesized that her new breasts might not have any physical weight unless he snapped a picture of them to apply the filter. Despite this fortunate fact, Jack could tell that his blank staring would soon cause his mom to look down at herself anyway. Jack wisely pointed the phone at the floor, just as his mom began to check herself.

"You're acting very strange Jack.. have I spilled something on my top?" she asked, dusting it off.

Jack didn't reply as he wrestled with a fierce internal conflict. His brain told him that his mom wouldn't appreciate being gifted a whopper set of tits out of the blue. Could he do that to her? His other brain thrummed with lust and excitement. His nuts ached with need and the increasing amount of testosterone they were pumping into his body was clouding Jack's judgement. The memory of his mom with supersized titties tipped him over the edge. He could always just delete the photo later and everything would revert back to normal right?

Giving in to the devil on his shoulder, Jack typed an extra word into the Snapster filter field:
"really stacked"

"In for a penny..." he muttered and looked up to address Sharon.

"No mom, not magic tricks. Like I said, it's this new Snapster filter. I just typed in 'stacked' and it stacked the dishes," Jack explained, mischievous grin growing wider,
"but it can change anything else too, watch this!"

Aiming the phone at his mom, Jack quickly snapped a picture of her and held his breath.
A bright flash of light flooded over his mom, making her to squint, and then...

Nothing. An eternity seemed to pass as Jack anxiously flicked his eyes between the loading spinner on his phone and his mom's chest.

"Is something meant to be happ- EHAA!" his mom shrieked.

Sharon was interrupted by her top shredding apart as her tits suddenly swelled up. The previously modest lumps quickly expanded and filled up into perfectly round melons that strained against her shirt. Jack's mom now looked as he remembered from the filter preview, but judging from the creaking and groaning of her shirt, Sharon's boobs weren't done yet. Her nipples poked angrily through the increasingly stretched button-up, forcing their way to freedom. Finally the volleyball sized jugs exploded out of their confines, completely shredding the front of Sharon's shirt, which fell onto the floor. Jack's mom instinctively covered her nipples, involuntarily moaning as she grabbed her swelling pillows. Her huge breasts swelled even larger splaying her fingers as she cupped them. Finally the growth halted. Jack's moms breasts were each easily twice as big as her head, and her hands could barely cover half of her massive engorged areolas.
