The Back Seat Shrunken First Semester chapter 8 by VirtualFootprint and maximally

The hot, steamy environment of the shower was exactly what Max needed after his hour-long armpit adventure. He stood with his eyes closed, face turned up into the spray of water; just appreciating the warmth, and the air that smelled of fresh citrus shower gel rather than body odour.

He stumbled as the surface beneath him shifted. Max was stood on Kaley’s open palm, held just out of the full force of the shower where he could enjoy the lighter mist. She must have adjusted her arm slightly without realising, because he now found himself stood mere inches from her gigantic, soapy breasts.

He gulped and turned away. He didn’t want her to think he was a creep, only here to stare at her. But she did have a very nice body. Slim around the waist but curvy in all the right places, wide hips and full chest, her skin shining almost golden in the heated water…

“Max? Do you want some more soap?”

“Huh?” He blinked out of his stupor. “Oh. Yeah, thanks.”

She smiled and lowered him to her navel, letting him scoop a handful of suds off her belly to wash with. He was glad she didn’t seem uncomfortable. Outside Kaley had struggled just to mumble through her suggestion they shower together, but once inside she’d warmed up quickly. In fact he suspected she was pleased he’d preferred to stay with her.

Lost in thought, Max’s eyes wandered down until he realised he was staring directly at the smooth, soapy space between her legs. He blushed and turned his head immediately upright – now looking up at her underboob, two pillowy mountains resting above him.

He shook his head and closed his eyes. “I’m not here for that!”

A few minutes later the pair exited the shower, freshly washed, towelled and dressed, and both feeling much more refreshed.

“I was thinking I’d pick up a coffee on the way home,” mentioned Kaley. “Can I get you something?”

He thought about it. “That does sound nice. But I obviously couldn’t have a whole coffee to my – ”

Just then he was interrupted by the locker room door swinging open. He had just enough time to see Kaley’s eyes widen in panic before the world lurched around him, as the giantess wheeled him behind her back and dropped him down the back of her panties!

Luckily the new arrival didn’t seem to notice anything off. She met Kaley’s eye and smiled. “Hi!” She waved. “Just finishing up, huh?”

“What?” Kaley asked. “Oh, um... yes. We – I mean, I – was just leaving.”

“Nice, get that early morning grind. I totally respect that. Now you have the whole day ahead of you, right?” She grinned, hands on her hips. “I’m Nikki, by the way.”

Within the fleshy walls of Kaley’s butt, Max stiffened. “Nikki Allais? From high school?” Had Max been able to see, he would have instantly recognised his former classmate by her dirty blonde hair, freckles, and athletic build, the latter of which she was now subtly trying to show off in front of Kaley.

“Not to sound like, you know, a stalker. But I was watching you for a minute out there, and I noticed something,” said Nikki, stretching her calves.

Now Kaley stiffened. Her buttocks clenched tight around her shrunken passenger. “What?”

“Your squatting form,” she replied, to both giantess and tiny’s relief. “It was… pretty good? Not bad. But it could be tightened up a little. If you want I can show you!”

“N-no, that’s okay.”

“Come on, it’ll just take a second!”

Before she knew it, Kaley was half-crouched in the middle of the locker room with this unknown woman stood behind her, lightly brushing up against her as she made minor adjustments to her form.

“See, here? You want your feet spread out just a teeny bit wider.” Nikki instructed. “Also, your toes should point out a little. Perfect! Now, the key to squats is how deep you can go. Give it a try! Really get down there, you can do it!”

With Kaley’s ass meat muffling their voices, Max was left confused as to what was happening outside. Why was his old schoolmate talking to his new giantess owner? Why wasn’t Kaley leaving? And how much longer was he going to be stuck in her panties?

He was thankful at least that her butt was recently washed; he shuddered to imagine how bad it must have smelled before the shower. But an ass was still an ass, and beneath the orange-scented body wash there was a fouler, earthier scent emanating from her crack. Max lay back into her underwear like a hammock, eyeing that dark abyss uneasily.

Until suddenly his hammock constricted. As Kaley went into her squat, her panties were pulled taut, stretching tighter around her rear; the lower she went, the further Max rose, plunging him deep inside her crack.

“No!” Desperately he grabbed at the buttocks on either side to slow his ascent, but it was no use. He continued to slide inevitably upward, only coming to an abrupt stop once his face was mashed firmly against Kaley’s asshole.

Above, Kaley gasped. There was no mistaking that sensation. She could sense her tiny passenger struggling against her most intimate orifice, a feeling that was both ticklish and… strangely…

“Come on, keep pushing!” Nikki encouraged. “You can totally go lower!”

Instead she let out a quick, high-pitched toot.

PROOOT

Kaley stood bolt upright, burning crimson. The release hadn’t dislodged Max, unfortunately – she could still feel him wriggling about on her backdoor – but it certainly caught Nikki off guard.

“I’m sorry, I have to go,” she squeaked.

“Hey. Happens to the best of us!” Nikki grinned. “Nice meeting you, anyway. Maybe I’ll see you around?”

“Yup! Maybe!” Kaley hurried from the room, oblivious to Nikki’s eyes wandering over her body as she left. She was desperate to find somewhere private to dig Max out of her dirty crevasse. Unfortunately, the gym was already filling up with people.

“Sorry, Max,” she bit her lip. “Just hang in there a bit longer!”

Max was beginning to wonder why he bothered washing. He hardly ever seemed to average more than a few minutes before getting covered in filth again.

“Sorry… I’m so sorry.” Kaley murmured. “I bet you’re getting tired of hearing that.”

“Don’t worry about it,” Max replied, allowing her to deposit him in the safety of his display case. It had been a rough ride home, pasted snugly to her sphincter. Her intimate anal musk had permeated every fibre of his being, even before she’d begun to sweat.

“I just panicked,” she began, flustered. “I wanted to take you out in the gym, but there were people everywhere, so I left. I got halfway home before I realised, why didn’t I just go into the bathroom? So I took a detour to that coffee shop after all, but then I got there and there was a line, and I was already sweating by then and I knew it had to be miserable for you and I just – ”

“Kaley, it’s fine. It’s over,” he said, calmly. “I’m just tired, is all.”

She nodded. “Right, sure. I’ll let you relax for a while.” She turned to leave, but something made her hesitate. “I guess… it would have been good if there was a little pocket in there, some way to keep you secure. Right?”

Max stared at her.

She shook her head. “Sorry. Ignore me. See you in a bit!”

Once alone, he let out a deep sigh and rubbed his temples. He had a pretty good idea of what was in store for him next.

As expected, Kaley had a new product ready for him before the day was through. The pair were lying on her bed late in the evening, finishing up the end of a film. Kaley had microwaved a bag of popcorn and Max had been steadily working through a piece of his own. It was actually looking like it might be a nice, peaceful night in. Then she cleared her throat.

“So, Max. I was wondering if you wanted to sleep with me tonight?”

He almost choked on his popcorn. “What?”

She blushed. “N-not like that! I meant – here, let me show you.”

The awkward giantess got up and went to retrieve an item from her desk. When she returned, Max studied the item in her hands with a sense of dread, but no real surprise.

“It’s a panty pocket,” she explained. “I had the idea after our… accident this morning. Essentially it’s just an extra piece of fabric stitched into the seat, little holes for your arms, legs and head, so you don’t fall out. Or, um. In.” She played idly with the garment. “It’s very comfortable.”

“You want me to stay inside your ass all night?” Max asked weakly.

“The lecturer at that seminar mentioned many women like to keep their tinies on their person at all times. So it would be good to know we have a product to facilitate that even during sleep, in a way that’s also safe and comfortable for the shrunken individual.”

“It looks safe enough to me. Let’s call this one a success and skip the testing.”

Kaley just gave him one of those sad smiles that meant he had no choice.

That was how Max came to spend his night nestled between the buttocks of his giant owner, listening to the quiet sounds of her steady breathing above, and gurgling bowels below. The panty pocket kept him from sinking too low, thankfully, but it still sagged enough for him to make contact with her fleshy cheeks. Over time he’d ended up wedged between them.

Part of him didn’t even mind that much. Her butt was warm, and being smothered between her cheeks felt almost like receiving an enormous, jiggly hug. It was mostly clean. There was a bit of an earthy musk in the air, but he’d spent enough time enduring Kaley’s bodily odours in the past two days that it was becoming disturbingly familiar.

What he couldn’t get used to, was –

BBRRRRRPPPP

The noxious fart rippled up through Kaley’s cheeks and buffeted Max’s body. He twisted his body, but with the panty pocket restraining his limbs there was no escaping the warm winds wafting toward him, or the rich eggy smell they carried.

“This is ridiculous.” He took a sniff, gagging. “I shouldn’t be here. I should be back in my display case, tucked into a pair of clean socks.” A moment later, he wanted to hit himself. “No!” That wasn’t right either! He should be back in his own bed, in his original dorm room, fully sized. What was wrong with him? Why was he so quick to accept this bizarre new reality?

That was the weird thing about life with Kaley. It was contradictory; both comfortable, and terrible. There were times where it felt like she was the kindest, most gentle person he could have hoped to be discovered by that morning after the party. Then, at other times…

FFRRRRRRPPPFFF

At other times, he wondered if he’d have been better off taking his chances with some unhinged Juno. His eyes watered, blinking through a haze of spoiled dairy.

Life with Kaley, he supposed, was like continually flipping a coin. Sometimes it was good, sometimes it sucked. You might spend an evening watching movies with snacks, or you might spend it buried up to your waist in booty, eating farts.

That was a more hopeful way to think about it, he decided. Yeah, this was a bad time. But that didn't mean there wouldn't be better ones coming.

All he could do was endure for now, and hope the coin came up heads tomorrow.
