Resentenced to Booty Duty A Shrunken Roommate (Re-upload) chapter 18 by copier · original author: azazel8

Morgan and Quinn went from the high of their respective adrenaline rushes to the low of mounting lamentation in record time as they looked at the pile of ruined green thongs, joining Avery in her obvious concern. To their credit, their concern didn’t stem from the destruction of their underwear but rather the knowledge that you were still lost. They hadn’t known you for long, and for most of that time you had been serving as your aunt’s thong, but they did care about you. If you weren’t any of these thongs, where had you gone? Were you still in the apartment? Had they lost you forever?

For her part, Quinn felt her concerns from earlier rising up again. Of the new fantastically absorbent thong she had acquired right around the time that you supposedly returned, and which she couldn’t remember buying for herself. Of the way in which it seemed to have stretched to fit her just right. To support and comfort her in all the right ways. Of how much use she’d gotten out of that thong over the last week, driving her to a new fitness routine. Of the way even now it was dutifully soaking up the fresh wave of sweat flowing from her rear. Shifting slightly, the pale girl felt her cheeks sliding around the captured thong, and was reminded of a program she’d seen her mother watching once, extolling the virtues of using willing tinies as clothing, noting just how comfortable they could be. Truthfully she didn’t want to think about it too hard, and certainly didn’t want to voice her suspicion.

If her suspicions were wrong, then she’d just be embarrassing herself for no reason and would risk losing the best thong she’d ever owned. But if she was right… Quinn swallowed firmly as she pushed her embarrassment aside. “Wait here. I think I know what happened to Hunter.” Questions followed of course, but the curvaceous girl waved them off and headed for the bathroom, her cheeks sliding around you once more as she shut and locked the door. Quickly removing her compression shorts, she frowned at how wet they were with the exception of a dry section right down the middle where the thong that could be you had gotten in the way. She felt that no normal piece of underwear could possibly be this absorbent, and your tormentor’s cheeks reddened as she began to shimmy you off.

For you, the run had left you near-catatonic, and you’d only just begun to regain your senses when you were suddenly pulled from the hellish embrace of Quinn’s rear with a wet slurp. Your passage wiped up more sweat, providing your wearer with a thorough cleaning as you moved, but you were happy at least to be given a chance to breath fresh air. You still burned from residual heat, and the smell of your roommate’s booty wouldn’t fade anytime soon, but it was enough just to be free, even if you remained in her grip and knew that you were inevitably fated to be returned to that same hell.

However, rather than being tossed in the hamper or carried back to Quinn’s bedroom, you instead found yourself lifted closer to her face and unfolded, held wide as worried blue eyes examined your form. You wanted to ask why she was looking at you like that, hoping that it might mean you were saved, but you still couldn’t speak, stubbornly held in shape. Instead, it was your roommate who spoke. “I don’t know if that’s really you Hunter, but if it is I’m so sorry for the last week. I’ll make it up to you.” You were nearly struck dumb by the statement, even as the light of salvation blossomed inside of you. Was it true? After more than three months of life as a thong, were you finally being saved? Your body was laden with sweat, gas and grime, but as your potential saviour pulled her shorts back on and left the bathroom you felt as if you could float away on your emotional high.

Back in the living room, Morgan and Avery met their roommate with quizzical gazes as she walked back in holding a tan thong in her hands, the fitter of the two going to speak before being cut off by Quinn. “Yes, I know it’s tan, but listen. I started using this around the time that you said Hunter came back, and we think Avery might have put him through the wash. What if his colour changed in the wash? What if I’ve been wearing him all this time?” Internally you screamed in agreement, glad that logic was finally winning the day and leading you to safety. Sure that the others would understand.

Unfortunately, your hopes were brought crashing down as Morgan’s eyes slowly scanned your form and she shook her head, reaching down to grab Norah’s note from the coffee table and holding it up for Quinn. Your pleading gaze went unseen as the brunette spoke. “I’m sorry. I want to find Hunter as well. But his aunt clearly said he would be trapped as a green thong until the solvent was applied, not tan. The wash won’t undo that.” She sighed, though her disappointment was nothing compared to yours. “Besides, both Avery and I saw him. He was definitely green. That’s just a normal thong.”

You wanted to cry out in pain and protest, hating the fact that your aunt’s wording had convinced Morgan that your colour was as locked in as your form, snatching away your chance at salvation. For her part, Quinn seemed relieved but not wholly convinced, keeping that flame of hope alive for just a little bit longer. “Do you think maybe we should try the solvent anyway? Just in case. I mean, this thong is way stretchier than usual, and it’s super absorbent and incredibly comfortable. I’ve worn it nearly non-stop for a week and it may actually be more comfortable than when I first started using it. Like it’s adapting itself to my rear.” Her concern and conviction touched you, though you couldn’t help but worry a bit at how satisfied she seemed to be with your performance as her new thong.

Avery tilted her head a little as she adopted a quizzical expression. “Why are you so worried now? Didn’t you say that tinies need to take care of the-” The pinkette was cut off as Quinn met her gaze with hard eyes and a clipped tone. “I don’t want to lose another friend like this okay!” The curvier girl sighed, running her free hand through her hair while the other tightened around you. “I’ve had friends disappear like this when I was at high school okay. One day they’d be there and then the next they were gone. Sometimes they’d turn up again, but sometimes they wouldn’t. I don’t want that to happen here.” Privately she was fairly sure her mother may have been involved in some of those disappearances, though she couldn’t prove it. It just seemed too much of a coincidence that the boy who had asked her to prom had seemingly just vanished on the way to pick her up for the dance.

Clearly concerned, though no longer for you, Morgan put a comforting hand on Quinn’s shoulder, while shooting her sister a pointed look. “I get it. Really. We’ll find Hunter, I promise. But we only have so much solvent, and it’s not worth wasting it and ruining a perfectly good thong just because it’s performing beyond your expectations.” She smiled then, an expression that you knew spelled doom for you. “Keep them. If they make you comfortable, then that’s great. And if they’re going to help you meet your fitness goals, that’s even better. I’m sure Hunter would say the same thing if he was here.” There was no maliciousness in the brunette’s words. She truthfully believed that you could not possibly be her friend’s tan thong, having no idea what she was condemning you too.

Desperately you tried to struggle, to move even the smallest amount. Anything to give Quinn reason to hold onto her misgivings. To reject the seeming logic of Morgan’s words. But you had known from the start that it was useless, and your fate was sealed as your unknowing tormentor, swallowing her guilt and self-doubt, gave in. “You’re right. Thanks.” Your silent screams went unheard as the clearly dejected girl headed to her own room, setting you on the edge of her bed as she stripped down in earnest, giving a show that you couldn’t even enjoy in your current state as sweat-soaked clothes were folded and set aside while a fresh set was laid out beside you. There was no new pair of panties or thong set out, and you knew what was coming even before your roommate reached down, your protests mute and useless as the now naked girl moved you down to her feet and stepped into you.

As you began to slide up those long legs once more, Quinn looked down at you with a complicated expression, though one that was rapidly setting into one of determination. “I really hope that’s not you Hunter, and if it is I’m so sorry. But… I’m going to try not to think about that anymore and just enjoy how great a thong you are.” She laughed a little to herself, shaking her head as she started to pull you up in earnest. “It’s just a thong you idiot. Stop talking to it.” You wanted to correct her, but there was nothing you could do as you lost sight of her pretty face and were plunged back between her cheeks once more, returned to the hellish prison of the curvy girl’s massive rear as she adjusted you to sit just right and pulled you tight against her flesh. Despite herself, Quinn smiled a little as her buttocks clamped tightly around you, remembering just why she had fallen in love with this thong.

Buried once again in booty, you lost all perspective of the outside world, your senses consumed with the heat, pressure and smell of your surroundings, which only became worse as your captor pulled on a tight pair of jeans to truly seal you in. Meanwhile, your unaware roommate set a hand on her hip as she glanced back at her massive rear, chewing her lip for a moment as she tried to put aside the seemingly disproven possibility of it being you. “Maybe I should get them dyed so I stop thinking about it. Heh, just as long as I don’t accidentally dye them green to match poor little Hunter.” She frowned. “Or maybe I should just give them away, if they’re going to keep bothering me like this.”
