As the first day of the contest began, it presenteted quite the opportunity for Susan and Linda Zimmerman.  Susan and Linda were sisters, ages seventeen and sixteen respectively.  Seeing how the two girls owned and knew how to operate a shrink ray, this seemed to be the perfect way to make a quick ten thousand dollars.

"Are you sure this is safe?" Susan asked, tenatively.  Of the two sisters, she was the older, more mature one, and her mind was drifting towards the potential consequences of sneaking into a pair of their mother's underwear.

"Trust me, it'll be fine," Linda insisted.  She was much more carefree and saw this as an opportunity of a lifetime.

"Are you sure we can't let mom know first?"

"Absolutely not!" Linda said.  "We'll get disqualified, and I'm not risking losing ten thousand dollars."

Susan exhaled.  Ten thousand dollars would go a long way and seemed to be worth the risk.  "Alright, let's do it.  But we need to go now, mom's in the shower."  The sisters entered their mother's room, where it turns out she had her clothes laid out on top of the bed.  There on top, was a clean pair of white underwear, which both girls realized would be extremely tight on their mother.

At that moment, they heard the water stop.  "Oh shit, hurry," Linda said.  She grabbed Susan's hand and climbed up on top of their mom's bed.  Standing over the underwear, Linda pulled her sister tight.  "You really?" she asked, turning the shrink ray at themselves.

"I...I don't," was all Susan had time to get out.  Linda pulled the trigger regardless, causing both girls to dwindle down together to a miniscule size.  

The girl's mother, Debbie Zimmerman, exited the bathroom, her naked body cutting through the waves of steam.  "Hello?" she asked.  "Girls?  You here?"  She could've sworn she'd heard her daughters outside of the bathroom door.  She shrugged.  She did not have much to do today and was looking forward to a relaxing day of laying around.

Meanwhile, on a pile of their mother's clothing, the two teenage sisters were aewstruck.  They were incredibly tiny, standing only a mere one millimeter tall.  "Holy shit," Linda mumbled.

"This is the smallest we've ever been," said Susan.  The two girls had played around with the shrink ray before, but had never been this small.  Before they could truly process the change in perspective, the ground started to shake.

"Oh my god, run!" screamed Susan.  It took all over Linda's strength to hold her panicking sister and tried to keep her calm.  Approaching the bed was the girl's titanic mother, eye's focused in on the underwear.

"Sue, we need to stay still," yelled Linda.  "We just gotta get one picture and get this over with."

Completely unaware of the tiny girl's presence, Debbie reached down and lifted up the pair of underwear.  She then lowered it back down and began to inser one leg.  The constant movement of the underwear caused both shrunken sisters to become extremely nauseous.  Then the giant leg flying past them through the opening of the leg hole, caused both girls to scream.  They had nearly been crushed by their giant mother's leg.  Debbie began to inser her other leg, repeating the process with her two shrunken daughters, and then proceeded to pull them up.  

The underwear cupped Debbie's ass quite tightly, which meant the two shrunkedn girls were quite close to their giant mother's ass cheeks.  The smell and heat from their surroundings made both girls light-headed and want to vomit.  "Hurry up, I want to get out of here," cried Susan.

"Calm down sis, we just need one picture," stated Linda.  "Now come here and smile."

Both girls did their best fake smile, but the sweat from their mother's ass was not making it easy.  Turning on the flash, Linda snapped a quick picture.  "Did you get it?" coughed Susan.

Linda showed her the picture.  "Sure did, now just gonna tet the number."

At the studio, 201.5, The Mini, Jay and Shelly were joking around on air.  Then their contest phone number went off.

"Whoa hold up, it looks like we have an entry from Linda and Susan Zimmerman," said Jay.

"Alright, your pic looks great!" said Shelly.  "First we just have to verify that your picture is legit."  Both hosts turned their attention to a tech assistant.  They watched their assistant run the picture through a database.  What they were checking was any social media activity, indicating the mom was aware.  They also checked to ensure the picture was not photoshopped.

"Well Linda and Susan, we've got some good news for you!" Shelly said.

"Your picture is legit and excellent.  We are gonna post it on our website and are mailing a ten thousand dollar check to your house," yeled Jay.  "Good luck to you both!"

Inside their mother's underwear, Linda and Susan were hugging.  "Holy shit, we got it!" yelled Linda.  Both her and Susan were ecstatic, but then heard something that froze them.  It was a deep groan.

"Linda," Susan said.  At that moment, a disgusting blast erupted from their mother's ass, spewing toxic gas into her underwear.  The girls doubled over, and Susan even vomited.

"UGH, SCUSE ME," laughed Debbie.  "THANK GOD I'M ALONE."

Inside the underwear, the girls were in chaos.  Their ears were ringing from the blast.  Their eyes, noses, and mouths burned.  "Linda, we need to get out of here," sobbed Susan.

The girls began to make their way to an exit from the underwear, when out of nowhere, Debbie let loose another disgusting blast.  Debbie had slightly turned her body with this fart.  The blast was powerful enough that it blew Linda's one-millimeter body straight out of the underwear, knocking her out in the process.

Meanwhile, Susan was blinded and in panic.  She knew her sister was gone, and that she also had the shrink ray.  She ran blindly, desperate to escape somewhere else.  She began feeling against her mother's leg for navigation. 

Previously minding her own business, Debbie felt a slight tickle in a sensitive area after her second fart.  She lowered a finger down to scratch the itch.  In the process, she scooped up her oldest daughter on her index finger.

Susan was in a panic, unsure of what was going on.  She knew she was being lifted up, and her vision started to return, only to find a giant eyeball starting back at her.

Debbie looked at the tiny creature on her index finger in disgust.  "UGH, ARE YOU FUCKING KIDDING ME?" she sighed.  "ANOTHER LITTLE PERVERT SNEAKING INTO MY HOUSE.  LET ME GUESS, YOU SHRUNK YOURSELF DOWN AND ARE TRYING TO SPY ON MY DAUGHTERS?" 

Susan cried and begged her mother to notice it was her.  "Mommy, please!" she screamed.

"WELL I'VE GOT THE PERFECT PUNISHMENT FOR YOU," Debbie slowly deposited her one-millimeter daughter onto her tongue.  She could not hear her tiny daughter's pleas and slowly set her back towards the abyss that was her throat.  She then swallowed, unaware that she had just doomed her daughter.

Eventually, Linda came to her senses on her mother's bed, still shrunken.  She had no idea yet of her daughter's face, or that she now had all the money to herself.
