Knowingly But Caringly Used (Part Two) A Shrunken Roommate (Re-upload) chapter 9 by Bobob1

Two and a half weeks had now passed since Avery had first molded you into a cover for Morgan’s yoga mat and gifted you to her, and you were beginning to lose your sense of time. Morgan treated you the exact same each and every day, cheerful and caring, gentle as she could be without messing up her routine, and holding a one-sided conversation surprisingly well. Even still, your mind was beginning to lose it. Why wasn’t the replacement in yet?

From out of your vision, you heard the door swing open, and knew from routine that Morgan was back from breakfast. This meant another exercise session was coming up. You’d become accustomed to her weight and methods of exercise, your squishy body adapting admirably to the torment. It didn’t mean you liked it, but you tolerated it. Steeling yourself for another day of the same sweaty session as always, your preconceptions exploded into unpredictability as someone decidedly NOT Morgan stepped into view.

“She said just grab two random yoga mats…why did she have to be so vague?” The black-haired giantess groaned, brushing some hair out of her face. “Why did I agree to this is the better question? Ugh…oh well. I’m not about to back down.”

Your heart leapt into your throat as you beheld Quinn standing above you. Even months in the same apartment could never fully prepare you for gazing upon her, and her current attire was like no other that you’d seen on her before. Due to cruel fate and the occasional carelessness of your roommates, you’d seen all three of them naked on plenty of occasions. Still, less was more from time to time, and this was certainly one of those times.

Quinn’s face was mostly obscured due entirely to her mammoth breasts barely contained in a skintight black tank top that left most of her midriff exposed. More jaw-droppingly, her gargantuanly alluring derriere was being squeezed tight by a pair of black compression shorts so small they looked painted onto Quinn’s skin. Her gelatinous butt cheeks were being compressed, Quinn’s crack eating up half of the shorts fabric. Every exposed inch of her body jiggled from the slightest movement.

Quinn finally glanced downward and spotted you. Shrugging, she bent down to retrieve you. “Ah, this one will work, I guess.” She surmised, and your blood ran cold as she picked you up. You wished desperately that you possessed any control of your body, but Morgan had long ago stomped any residual strength out of you. You doubted you could even reform your face without outside help, let only break the bonds of Avery’s superglue.

Carrying you and another yoga mat downstairs to the living room, you were hit with another paralyzing revelation. Due to wanting to preserve her own modesty and respect your heartfelt decision, Morgan and sworn of telling Quinn the truth about your identity that last few weeks. Seeing as Avery had forgotten the truth entirely just a few days later, she hadn’t slipped up either. Quinn was wholly oblivious.

Unrolling you in the living room, Quinn stepped up onto your body and reflexively drummed her toes along your face. Instantly, the significantly higher weight compared to Morgan offset your previous adaptability. Your body groaned in discomfort, especially as a few droplets of sweat trickled off Quinn’s bare feet and into your mangled eyes. A true exercise routine had yet to even begin, and you started to mentally cry out for mercy.

As if arriving on cue to save you, Morgan strolled into the room, two ice cold water bottles in hand. Giving one to Quinn, the brown-haired giantess flashed a confident grin. “Thank you so much for finally agreeing to all of this, Quinn. If all goes well, we could make this a routine!”

Quinn raised an eyebrow. “That’s a big ‘if’, Morgan. I’m going out on a limb by trying this. I don’t really DO formal exercise.”

Morgan waved dismissively. “Ah, that’s fine! I’ll be glad even if it’s only this once.” She eyed Quinn with an impressed expression. “Glad the biggest pair of compression shorts I had fit you. Even if they are a bit…” Morgan trailed off, and Quinn groaned, the curvaceous girl fully aware of how ridiculously immodest she looked. Morgan recovered quickly. “Anyway, thanks again!”

As she smiled warmly at her good friend, Morgan’s eyes happened to drift downwards, landing on the particular mat that Quinn had picked out for herself. Morgan frowned for a second, puzzled, then spotted your one barely noticeable eye, staring straight up. The only visible part of your body, and the exact same sign Morgan had used for the past few weeks to help keep you separate from her other yoga mats. Morgan paled.

“Uh…Quinn, wait–” Morgan whispered softer than she’d intended, and Quinn cut her off, having not heard her at all.

“Listen, Morgan. I might sound like an unenthusiastic brat right now, but it really does make me happy to spend time together. Also, I might not do yoga and stretches and all that…ever…but I DO work as a lifeguard. I walk, swim, and sometimes sprint for hours a day. I’m not the fittest girl, but I’ve got the stamina to keep up with you.” Quinn explained her standpoint thoroughly, uncharacteristically wordy.

Morgan bit her lip nervously. “And…uh…what do you mean by that? The thing is, Quinn, you’re actually–”

Trailing too quietly, Quinn unknowingly cut Morgan off again. “I mean that you shouldn’t hold back! Put me through the wringer. Every single stretch and exercise you can think of. If this ends up being just a one-time thing with us, I don’t want regrets.” Quinn stomped her foot for emphasis, and Morgan winced as Quinn’s sole slammed into your eye. “Let’s sweat and stretch for however many hours it takes. If this yoga mat and I aren’t thoroughly drenched by the end of it, then we keep going!” Quinn allowed herself a rare smile.

Under normal circumstances, Morgan would be on cloud nine to have such an enthusiastic and capable exercise partner. However, her mind was instead racing with the implications of you suffering as a blissfully unaware Quinn’s yoga mat for an entire intense session. She herself had treated you as carefully as possible, but with a no-holds-barred Quinn? Morgan could only imagine the hell you’d be put through, to say nothing of the obviously significantly move oppressive weight you’d be dealing with.

However, the only solution would be to tell Quinn the truth about where you’d been all the past weeks. Not only would it be admitting to an elaborate lie for all this time, but Morgan had to wonder if Quinn would be upset at how she’d treated you like an object for so long (even if, as far as Morgan believed, it had been your idea to start with). Even worse, Morgan wondered if Quinn would be angry at you for doing something so reckless as being molded into a yoga mat. Her stance on tinies was a bit more complex than Morgan could puzzle out sometimes.

Still, Morgan needed to make a decision, and make it now. Sparing one last look at your mangled, yoga mat body, Morgan gazed right at Quinn, who was still smiling. Gulping anxiously…
