You were too late. Even as you jumped out and your body cleared Josie's titanic ass cheeks, the tidal wave of her buttflesh caught you by your suit's tail and yanked you back into her depths. The cheerleader's enormous behind raced by you, and you were slammed hard against her anus. By the time her jiggling bottocks settled, you were caught up to your neck in her rectum. Only the suit's comical, oversized ears prevented Josie from forcing you entirely into her body. But despite your best efforts to free yourself, you were stuck fast, and could only gaze helplessly through the dark "canyon" at the fabric of her panties. Then her sweaty, smelly mountains came together, and you were sealed off from the light. The occasional drop of sweat became an unending stream. You bowed your head, waiting for the game to end.
Far above, Josie smiled as she felt the new mascot -- you -- struggle futilely in her gargantuan butt. Then her thoughts returned to cheering, and all thoughts of the mouse mascot drifted to the back of her mind.

Much later, the game was finally over, and all the cheerleaders came filing in, bodies slick from exertion. As Josie and Amy packed, one of the cheerleaders wondered, "Where's our little luck charm?"
All eyes turned to Josie. She grinned, pulled down her shorts, and spread her cheeks. Surprised by the sudden burst of light, you thrashed around and tried to avert your eyes. Your captor rotated, displaying her rear end rodent to everyone. You saw the giggling cheerleaders, the exhausted athletes who just smiled and rolled their eyes... and a decidedly displeased Sylvia. She coughed sternly, and the cheer captain released her buttocks, which smacked back into position like bulbous pendulums, and pulled up her shorts.
The conversation that followed started out muffled by Josie's volumous posterior, but became more clear as voices were raised:
"...HAVE YOU NO RESPECT FOR OTHER PEOPLE!?"
"HEY, HE LIKES MY BUTT, SO I GAVE IT TO HIM!"
"I HAVE HALF A MIND TO GO AND--"
"AND WHAT? SAY 'OOH, I'VE BEEN SHRINKING REAL PEOPLE AND PRACTICALLY ENSLAVING THEM, BUT 'CAUSE SOMEONE ELSE IS ALSO HAVING THEIR LITTLE FUN, I'VE JUST NOW DECIDED TO SPEAK UP LIKE I'VE DONE NOTHING WRONG'?!!"
Then an impact sent ripples shuddering down Josie's booty. One of them slapped into you, slamming you into unconsciousness.

When you woke up, your crush's butt swayed up and down, side to side. You were still feet-first, neck-deep in her colon, but that was about to change. A titanic hand descended from the heavens and plucked you from your prison, carrying you into the light. You shivered as you felt the cold night air. Josie looked down at you. You were in a parking lot, next to a car. "Sorry, rat-boy, but Sylvia can just be so anal, you know? I mean, what an absolute asshole. Anyway, are you ready to party?"
Not knowing what else to do, you nodded. Josie smiled devilishly. "Great!" With that, she swung open the driver's side door and tossed you into the seat next to her. By the time you recovered your bearings, the passenger door opened and Amy plopped her sweatpants-clad ass on top of you. You saw a grey wall, then darkness.
"So, where are we going?" Amy asked, shifting in her seat a little as she turned to her friend. You were dragged roughly across the pad with her far buttock.
"Olivia's house, for her party... You remember Olivia, right? Bit flirty, wears skintight shirts and shorts stuffed all the way in her buttcrack?"
Amy shifted back, bringing her full buttock on top of you. She remembered Olivia, oh yes -- big breasts, big butt, not afraid to do anything, especially when 'anything' meant showing off her assets. Amy detested her for that alone, but she was a generous person, though so nearsighted she needed glasses an inch thick just to see the board in class. Olivia did nothing small, especially not parties. This would be a blast. "Anyone we're picking up?"
"Yep. Emma and Alexa."
And at that moment, the back car doors opened. Emma came in first. She had long brown hair, glasses, and would do anything for a dare. For one dare, you remembered as you were smothered under Amy, she tried to give you a black eye by hip dropping on you. She had a decently large butt, so it took a while, but you didn't complain. Amy didn't mind Emma either, and secretly gloated over the fact that she was one cup size larger than Emma.
Then Alexa entered. She had, compared with the other girls, little in the way of physical assets, and had long limbs, occasionally giving the impression of a sentient bundle of sticks. She was also extremely pacifistic and quiet. Why she was going to a party by Olivia of all people was a mystery to both you and the giantess whose behemoth backside was bearing down on you, trapping you in an air pocket that was rapidly heating up.
With everyone in, Josie revved the car and drove out of the parking lot. Amy leaned forward -- temporarily giving you a breath of fresh air -- turned on the radio and flipped through the stations until she found one she liked.
"Alright! Herman and the Mouse-Men!" She dialed up the volume a good bit, then slid back to her original position -- inundating you in a sea of the soft seat of her sweatpants. As she ground, twisted, and mouthed the words to the song, Emma and Alexa groaned.
Emma's purple lips pursed together disapprovingly. "Don't tell me you like their cheesy crap, Amy."
"Oh, come on, Emma! They're the best thing since the Rat Pack!"
Alexa, pointedly gazing out the window, muttered, "But the difference is that I liked Sinatra."
Amy continued bouncing and grinding in her seat, still unaware of the tiny, actual mouse-man she was shaking along with her rump. But as she crashed back into her seat for what seemed to be the thousandth time, she felt what was almost like an itchy lump on her rump. She was about to investigate with her hand, but Josie, eyes still on the road, coughed and shook her head slightly. The hand went back to the dashboard, quietly tapping along as the song ended.
Eventually, finally, at last, Josie's car made it to Olivia's house. As the three passengers made to leave, Josie turned and said in a louder-than-normal voice, "Amy, what's that on your ass?" Before Amy could turn around, Josie's hand snaked out and quickly peeled you off of her gigantic butt cheek, then held you up for all to see. Emma and Alexa squinted at it through their glasses. "It might be... a bug?"
Josie smiled, though to you it seemed more like a grimace. "Well, a pervert bug. What do you say we play a little game before we enter Olivia's fine establishment?"
Instantly, Emma said "Yes!" and Alexa said, quietly, "No."
"Then it's decided!" Josie grabbed what appeared to be a half-filled glass bottle, uncorked it, and dropped you in it. Thwn she sealed it and set it on the middle back seat. "Spin the bottle! Whoever wins gets drink and bug!"
"...Is that beer?" Alexa asked.
"Nope, it's an old-style bottle of Coke." It was, in fact, beer.
"Fine then. I'm in." With that from Alexa, Josie nodded and spun the bottle, which whirled until it pointed to...
