It was a warm summer afternoon and Megan was lounging around her parents house on summer break from college. Her younger brother Tommy, who had just turned 12, was sound asleep in his room after staying up late playing video games.

Megan had just downloaded a new app on her phone called "Shrink-O-Matic" that claimed you could shrink objects down to a tiny size just by pointing your camera at them and tapping the screen. Megan was highly skeptical it would actually work, but decided to test it out for kicks.

She crept into Tommy's room and pointed her phone camera down at his sleeping form. His shirt had ridden up a bit exposing his chubby tummy. Megan snorted to herself, her brother was such a little pudgeball. She lined up the crosshairs on her screen and tapped the big red button. But nothing happened. Figures, what a scam, Megan thought.

She was about to leave when Tommy suddenly let out a yawn and stretched. But something looked very different about him. Megan blinked in surprise. Was Tommy smaller somehow? No way...

Tommy rubbed his eyes and sat up, realizing he was now only about 6 inches tall! "What the hell?!" he yelped, looking around in a panic. Megan just stared down at him in shock. Holy shit, the app actually worked!

Just then, their mother Janet came waddling into the room, her size 18 frame barely squeezing through the doorway. She was wearing a tight tank top that strained to contain her massive boobs and a pair of short shorts that showed off her thick thunder thighs. On her feet were her favorite pair of black high heel mules.

"Tommy, are you still sleeping...oh my God, what happened?!" Janet gasped in horror, seeing her tiny son on the bed. She wasn't wearing her glasses so he looked like a little doll to her.

"I don't know, Mom, Megan shrank me with her phone or something! Help!" Tommy cried.

"I'm calling your father!" Janet said, fumbling for her own phone on the nightstand. In doing so, she lost her balance and tipped forward, her heavy body crashing down right on top of Tommy!

"AAAHHHHH!!" Janet screamed as she fell. She landed in a sprawling heap, her big, soft ass smashing Tommy completely underneath it. Her thick, meaty thighs pinned his arms. Tommy was utterly smothered by his mother's tremendous weight.

"Mom! MOM! Get off me!!" Tommy shrieked, but his tiny voice was completely muffled. He was trapped between his mother's huge ass cheeks, which engulfed him entirely. He could feel the heat of her body, smell the scent of her sweaty crotch through the thin fabric of her shorts. Her fat ass rippled and jiggled on top of him as she squirmed, trying to get up.

"Oh fuck! Tommy! I'm so sorry baby!" Janet wailed, finally extracting herself. She stumbled to her feet, her heavy tits swinging wildly. Tommy lay there on the carpet, dazed and gasping for air. His entire body was bright red from the impact of his mother's crushing ass.

"Tommy! Oh God, are you okay? I didn't mean to...I'm sorry!" Janet blubbered, her face crumpling. Rivulets of sweat ran down her fleshy cheeks and double chins as she shook like a leaf, horrified at what she'd done.

"P...please Mom, help me..." Tommy croaked weakly from the floor, still seeing stars. His sister just stood there gaping, her mouth hanging open.

"I don't know what to do! This is insane!" Janet babbled. She looked around wildly, her huge tits wobbling. Her skirt had gotten tucked under her big ass somehow and was hanging off her waist, exposing her black granny panties.

Suddenly, Megan stepped forward. "Don't worry Mom, I'll figure this out," she said, holding up her phone. "I think I can use the app to turn him back to normal size. Just...just don't smush him again, okay?"

"I'm sorry! I'm so sorry!" Janet blubbered, her whole body quaking and quivering with sobs. Her masssive, pale ass cheeks jiggled hypnotically as she shook. She quickly turned away to try to pull her skirt back down over her ass, her face burning with shame and humiliation.

Tommy just lay there on the carpet in a daze, still reeling from the sensation of being sat on by his mother's enormous ass. He could smell the stink of her sweaty butt crack and feel the lingering heat of her body. God, he hoped his sister could fix this and turn him back to normal! Being smothered by his mother's fat ass was the most horrifying thing that had ever happened to him...
