More Sisterly Workout Shenanigans
"Well, first one was a workout for me, and the next one was for both of us, so I'm thinking the next one should be for you" Ariadne replied.

"Wait, what?" You said, but rather than answering, Ariadne sat down on a bench and giggled, bringing you to her massive thighs, her tight leggings leaving very little to the imagination. Like her butt, they were really big but looked soft, as those chiseled muscles had a pretty generous fatty layer on top.

Then, slowly brought her thighs closer until they lightly touched, dropping you in the newly created space in between. You couldn't believe how utterly huge they were up close, they felt like they were as big as a mountain range if not even bigger. You landed with a slight bounce, which slightly tickled her.

"What do you think? I think they should be soft enough to be safe for micros" She asked while looking down at you with a smile. You were mildly embarrassed but at least she seemed right, you could still feel the hint of something extremely heavy beneath the squishy layer you rested on, but it felt soft enough, even if nowhere near as soft as her boobs, or any of the other girls' butts.

"I guess so... but why did you put me here?" You asked, feeling a little afraid of being so blunt, but on the other hand Ariadne should be one of the people you could be this frank with, hopefully she wouldn't take it the wrong way.

"These are your training weights in a way" Ariadne said "I'm gonna slowly press my thighs together, all you have to do is push back against them with all your might, that's gonna be the workout!"

Your eyes widened at that explanation, Ariadne's thighs were huge and way heavy, your first instinct told you that this would be a terrifying end, getting flattened into oblivion but you reminded yourself that you had already endured some outrageously huge weights without getting anything other than your ego hurt.

"Are you sure it's safe?!" You asked somewhat nervously.

"Of course! I have read up on it, but most importantly, we already used to do this a lot even before that" She replied cheerfully
"It's a natural exercise for micros since they often end up there... plus, I remember a particular one that used to like it so much he asked me to carry him in my tights when I wore them" She chuckled.

Somehow, you felt deep inside that if the other you ever asked her for such a thing, it was simply to avoid her butt or her cleavage more than anything else. However you also realized you were in a checkmate, as changing this status quo might be worse in the long run, although Ariadne herself seemed to have a preference for carrying you around in her butt or cleavage anyway, so maybe it was worth giving it a shot?

Taking your silence as simply silent agreement, she nodded and began to press her thighs together, engulfing you into their enormous mass. She was surprisingly gentle, a hint that she really was used to doing this already. The squishy, slightly jiggly masses from both sides only enveloped you slightly but that was more than enough to get you to feel the warmth they radiated off, and even a hint of the sweat that evaporated off them, to you it was like steam, reminding you that you were indeed small enough to actually perceive someone's sweat evaporating... crazy, and maybe a bit interesting if you had a safer vantage point.

"Get ready to start pushing with your arms! It'd be better if you can also do it with your legs. I can feel how much you're pushing" She said and by the sound of it, the latter portion was intended to be reassuring given her tone, but it only meant that you couldn't just pretend to do something, and the sad irony was while you were inside Monique's and Snickers' humongous asses you pretty much already had needed to do something akin to this. Having no further choice, you obeyed, touching the two gigantic thighs using a hand for each, as well as a foot. They weren't exerting a whole lot of force over you yet, so it simply felt like a warm mattress.

That wouldn't last, as they began to press into each other, gradually but steadily increasing the force you were getting sandwiched with. You began to push back against these overwhelmingly huge meaty masses with all your might, mildly succeeding in making your hands and feet sink into their fatty surface.

"Good! Keep it up lil' bro!" Ariadne said, trying to cheer you as she increased the pressure. To her, this was barely an effort at all, but she had at least some awareness on how much it scaled for micros, even if her expectations were a couple orders of magnitude off, it was better judgement than many of the other girls who simply had no idea or didn't care to find out.

Ariadne's humongous thighs engulfed you with greater pressure, and you began to feel that incredible weight belonging to her dense muscles, although this didn't hurt you, it wasn't even on the same level as the squishing pressure that Lulu's, Monique's or Snickers' butts exerted on you in their idle state. As much as you may question this whole idea about exercises for micros, you had to recognize your big sis was being at least somewhat careful.

"Push a little harder, don't be afraid even if it tickles me" She said, giggling as she felt your diminutive limbs push harder into her thighs, despite their half tensed state. In response, she increased the pressure yet again. To you, this began to feel closer to the immense weight that you felt with the other girls and Lulu, and these fleshy walls weren't quite as yielding as their cheeks.

"Alright, now just keep pushing!" Ariadne said as she increased the pressure more, now this would be about the same strength she'd use if she were trying to hide something between her thighs or keep it from falling to the floor, but on the first day she wasn't planning on using her full strength on her little brother, though she hoped and meant to gradually build up to that point, to ensure that neither Lillian nor Jordana's oversized asses harmed you.

You remembered seeing some random videos where a hydraulic press crushed flat various objects, but only now you could relate to them on a deep spiritual level like never before, as you were experiencing something that felt similar, though still with a vague semblance of softness, the immense meaty walls seemed to be trying to squash you flat in between them and you still had to keep pushing away with all 4 of your limbs.

'Just how much longer...?!' You thought, straining yourself, feeling like you were reaching your limits, and just when you felt like you wouldn't be able to push anymore, the pressure eased all the way up to when she merely held you between her thighs. You were sweating and your body felt really hot, needing to take deep breaths while letting your aching body rest.

"Good job!" She said, giving you a cheerful thumbs up "We will have to do that more every day but for starters it was pretty good"

Finding yourself speechless from sheer fatigue, you simply allowed your body to rest on the soft mass of one of her thighs.

"Alright, we can rest for a bit" She said, and allowed you to rest for about 15 minutes before she picked you up again on her finger and brought you to her face "Okay, next exercise is really meant for me but I think you're gonna have to ride along"

"Huh?!"

"Yeah, I've got to do some squats, you know... trying to keep the balance between muscle and fat" She explained with a slightly apologetic look "With so many women around I'm a little worried something could happen if I were to leave you somewhere so you'll have to stick with me" And as she said that she began to lower you down and pull her leggings' waistband with her free hand.

"Wait, your butt again?!" You said in shock, forgetting about any subtleties you may have had earlier.

"I mean, I don't think you wanna swim in my boob sweat, do you? These cotton leggings will make sure it doesn't get too swampy back there at least" Ariadne chuckled "Plus, you could do some more exercise like the last one, only with some softer 'mattresses' " She smiled again.

Meanwhile, Isha had been observing from a safe distance, a little frustrated she couldn't do any more of her antics due to the nature of Ariadne's last workout, and this one seemed like it'd also be impossible for her to mess around with, though she found it interesting that your big sis didn't seem to have much trouble letting you get up close and personal with her own anatomy for the sake of exercising.

Before you could protest, you were dropped right into Ariadne's huge ass once more, soon feeling engulfed by the two immensely heavy but soft fleshy planetoids. She only gave you a slight warning before she began to do her squats, which drastically increased the pressure all over you to levels that surpassed her thigh squeezing with ease. How you didn't become flat as a sticker was anybody's guess, but this quickly became the routine tha you needed to endure somehow.

Clench, relax, clench, relax... this was all her humongous cheeks did every time she squatted, plus a sort of feeling of vertigo from going up and down so quickly. You bounced slightly in between them which tickled her in a pleasant way she was already quite familiar with but enjoyed nonetheless.

'He does feel good back there even if he's just tickling me... maybe he could stay there for the rest of my booty workouts? He gets to work out too!' She thought, thinking that this was the safest option to go with, counting on the sweat that would soon begin to appear on her skin to keep you cool and hydrated. She didn't see anything wrong with keeping you here like this, reminiscing about the many times she carried you around in her sizable behind.

However, as she began to do her squats faster, her stomach, which had been bouncing up and down alongside her motions, suddenly stirred awake and began to make some loud gurgling groans, reminding her of the protein shakes she happily downed last night, and they were coming back with a vengeance...
