Quinn relaxed as Morgan had unintentionally assured her that her new comfy, absorbent thong wasn’t you. Since Morgan hadn’t mentioned you being put through a wash cycle by Avery without her realising it, Quinn wouldn’t be expecting you to be a tan thong, only a green one. As she relaxed in her seat again, her massive cheeks unclenched, as they had been while she was concerned for you. This gave you a slight bit of respite, but not much.
All three months that you spent being worn by Norah couldn’t have prepared you for being worn by Quinn. The ludicrous proportions of her mighty backside put more strain on your body than any workout session with Norah ever could, and that was with her just sitting in a chair! Terrifying thoughts of being worn by Quinn during a workout flashed into your mind, and you silently thanked whatever deity would listen that Quinn didn’t seem like the most active of your roommates.
Your three roommates spent the rest of the day relaxing around the house, while you were left to the high pressure, smelly and sweaty environment of Quinn’s backside. Quinn barely moved from the chair, so you got no respite from your suffering underneath her, and even when she did, her movements pulled and stretched your limbs to the point where you feared they would snap around her wide hips.
The day passed by uneventfully and eventually you felt the cool air as you were tugged down past Quinn’s thick thighs and were dropped unceremoniously in her hamper with all of her other unwashed clothes. You looked up and saw Quinn, in all her nude glory, as she walked over to her dresser to find a pair of pyjamas to wear, eventually settling on a pair that would have been loose fitting on any girl that wasn’t Quinn. On her they were stretched to their limits around her hips and bust.
As Quinn flicked off the lights and crawled into bed you couldn’t do anything other than wallow in despair at how your life was going and the stench of Quinn’s dirty clothes. Eventually you drifted off to sleep.

Both you and Quinn were awoken by the sound of someone knocking on her bedroom door.
“Quinn, I’m almost ready for our run. Get your big butt outta bed,” you heard Morgan on the other side of the door. Quinn groaned, obviously having heard her as well.
“Ugh, why did I agree to start working out with Morgan,” Quinn groaned. She kept talking to herself as she struggled out of bed. “Oh well, I guess once I start to lose some weight it’ll be worth it.”
Quinn hurriedly gathered some workout clothes consisting of a far too small looking pair of workout shorts and a loose fitting top. As she rummaged in her underwear drawer she sighed in frustration when she saw it was empty.
“Man I need to get more on top of washing my clothes more often,” her eyes glanced towards the hamper you were resting in before settling on you. “I suppose wearing them for one more day couldn’t hurt.”
You mentally begged for Quinn to realise it was you as she lifted you out of the hamper and up to her face to inspect you. She crinkled her nose, expecting her new thong to smell pretty bad after being in her swampy ass all day yesterday, but was surprised to find that you didn’t actually smell very bad at all.
“Huh!” She exclaimed, becoming more impressed by this mystery thong with every revelation about it. “It doesn’t smell anywhere near as bad as I had thought it would, plus it’s not even damp! This is the best thong ever... if only I could remember where I got it.” She shrugged her shoulders. “Oh well I guess I’ll just have to get as much use out of this one as possible. I’m really glad Morgan has Hunter secured in her drawer, otherwise I’d be really worried this was him. At least this way I don’t need to give up my new favourite underwear.”
As Quinn smiled you could only scream internally as she shimmied out of her pyjama bottoms before stepping through your holes and dragging you up into the warm, crushing embrace of her ass. Your limbs were once again stretched to their limit around her hips.
Her workout shorts soon followed, which compressed her globular cheeks into their tight confines, which caused them to press into you even more than they already were, which you didn’t think was even possible. It was like being trapped in a vice, the two previously jiggling masses of buttflesh were pressing in tightly from all sides, they were at that moment taking up your entire world.
You were left to languish in the claustrophobic embrace of Quinn’s butt cheeks while she got changed into the rest of her workout clothes. Your situation didn’t change very much while this was going on, but you did get stretched to the point where you were sure you would break in half when Quinn bent over to tie her running shoes.
Quinn begrudgingly walked downstairs, her mountainous cheeks grinding your poor body as she went.
She joined Morgan in the living room, the much more athletic girl giggling at Quinn’s grim expression at the prospect of exercise.
“You could look a bit more enthusiastic Quinn,” Morgan giggled.
“Sorry, I just don’t do... exercise,” Quinn said half-heartedly.
“Don’t worry. I’m sure you’ll love it once we get started,” Morgan grinned, eager to get started.
You heard none of their conversation buried so deep in Quinn’s butt crack, at most you could only make out the muffled sound of Quinn’s voice, but you couldn’t understand any of the words she spoke. However, you definitely caught on to what was happening when the pounding you received from Quinn’s shifting cheeks increased in frequency and force.
After a few minutes of running Quinn was struggling to keep up with Morgan, and was hating every minute of it. As bad a time as Quinn was having, yours was infinitely worse.
Being worn by Norah while she ran was bad, but being worn by Quinn made that seem like a walk in the park. Quinn’s butt seemed to somehow be sweatier, crush you more ruthlessly and was even hotter than Norah’s ass during a run.
However, Quinn noted that her ass crack wasn’t as swampy as she expected it would be. She smiled, knowing that it was her new mysterious wonder-thong. As the run progressed Quinn decided that you would be her new go-to underwear in the future.
You were unaware that Quinn had decided to subject you to a whole lot more torture under her rear, since she hadn’t verbalised it, not that you would have heard it if she had verbalised it anyway.
As Quinn continued on her run with Morgan, her jiggling assets drawing meany eyes without her realising it, you dutifully absorbed the sweat that was pouring between her cheeks and resigned yourself to the fact that you would likely be dealing with a whole lot more of this in the near future.
*****
Seven days had passed. You had spent the vast majority of the week crammed into Quinn’s gigantic ass, dealing with all of the sweat, crushing and heat that her ass could inflict on you, along with the occasional fart.
This one week as Quinn’s underwear was in many ways worse than serving as Norah’s. While Quinn didn’t exercise anywhere near as much as Norah did, her larger rear got incredibly sweaty just by the fact of its size. Acting as Quinn’s underwear was also much more painful since it felt like you would snap at any moment, stretched what felt like past your limit around her ludicrous hips.
You were exposed to the light as Quinn opened the lid of the dryer, freeing you from the darkness and giving you a view of her beautiful face staring down at you, a sight which had been incredibly rare throughout the week since you had been crammed between her butt cheeks for most of it. As Quinn pulled you out and dropped you into a basket to take you up to her room, you saw Morgan walk into the room, holding a familiar green thong in her hand.
“Hey, Norah dropped off some of the solvent?” Quinn inquired.
“Yeah she gave me a few doses of it, just in case something like this happens in the future. Surprisingly forward thinking of her, I’d say,” Morgan smiled at the thong that she assumed was you. “Don’t worry Hunter, you’ll be back to normal soon enough.”
“Maybe for the best it wasn’t me that answered the door, I don’t think I’d have been able to keep calm around her after what she put Hunter through,” Quinn fumed, obviously still angry that Norah had worn you as a thong for three months. You knew she’d feel terrible when she finally figured out that you were her new favourite thong, if she ever did figure it out at least.
“Yeah she didn’t even seem that sorry about it, she just gushed about how helpful he is,” Morgan shrugged. “She seems nice, if a little ditsy. I think she actually believed that Hunter was cool with being her thong.”
While they were talking you watched as Morgan dropped the green thong into the washing machine and loaded it up with the detergent containing the solvent, before your view was obstructed by Quinn dropping another article of clothing on top of you, hiding you from sight. As you lay there, getting progressively more buried by Quinn’s clean laundry, you hoped that they would figure out where you really were when they realised that the green thong wasn’t you before Quinn wore you again.
1) Morgan tells Quinn and Avery that the detergent didn’t work, they figure out that the green thong wasn’t you. Quinn quickly realises that you were her thong the whole time.
2) Morgan tells Quinn and Avery that the detergent didn’t work, they figure out that the green thong wasn’t you, but Quinn doesn’t connect the dots.
3) They assume that there was a problem with Norah’s solvent, so they brainstorm ways to try and free you, thinking that you are still the green thong.
