Chapter 143 - #143 /the butts/

Gaia groaned a little and pawed at the place where her bottoms were digging into the increased acreage of her hips. An annoyed look on her pudgy yet pretty face. As she rolled onto her back, I couldn't help but notice how little she jiggled. Verifiably chubby yet still somehow toned and muscular enough to keep all that blubber fascinatingly pert. In contrast Deena was like wobbly chocolate gelatin as she rolled over onto her back. Repositioning her zip code warranting cheeks into a sitting position as they rippled shiny with the sweat of her exertion. Yet I couldn’t help but notice that Deena seemed to be panting about equal with her much more fit sister. I couldn’t tell if it was because Deena was used to being such a land whale, or if Gaia had burned through her stamina too much before she was lugging extra weight around. But I could tell that her lead, while certainly present, was no longer out of view of the stoic mountain of a woman who was coaching me. And something in her eyes told me she knew it too.

With a whistle from the coach the two big bootied sisters were in motion. Puffing and panting as they struggled against their obstructing oversized guts. I could tell she was counting mentally, and that in contrast to before she was really putting her back into the motions that went into lugging her big body up and down. Her bingo wing arms sandwiching against her porcine cheeks, hands locked behind her head. Even while every shift sent her body rippling, and beads of sweat dotted her immense figure I could feel beneath all that blubber there was strong and consistent form. She was still the slow behemoth her immense body made her. But she was giving it her all anyways. Her eyes had a certain sheen to them I hadn’t seen since she had been stuffing her gut full of calories. A quiet stoic sort of confident determination. Gone was the completely lazy fat ass who had been forced to attend these exercises and who had planned to coach a friend rather than pay them any mind.

Gaia meanwhile was having much more difficulty than she had before. Every attempt to sit up was met with a newly formed paunch pressing against jiggly overly thick thighs. The new front mass created by her softer figure was throwing her off completely. Her plush cheeks contorted into a pout as she pulled her body up and down. With such a huge size difference between the two her lead was undeniable. Especially given how her flab was holding to her perfectly carved frame. But she had descended from her heavenly perfection, into the grunting and puffing status of the average gym goer. But in her eyes nothing seemed to change. Her gaze still firmly locked onto her wobbling blob of a sister. Counting mentally as well in a mirror image. No matter how much softer plumper or less fit she became all she cared about was beating her sister. A ferociously competitive attitude that seemed to have bled into Deena amidst the heat of their competition.

Finally, the whistle was blown and both girls flopped onto their backs at finally being released from training. Their bodies shimmering with the shine of the sweat the warm up had inflicted on the shapely girls. Every breath a panting, puffing wheeze for breath as their guts and undersized chests rose and fell expanding outwards and inward with each frantic gasp. “How many did she get?” Deena asked, causing me to sit up a little to see over the periphery of her gut. “20” I explained with a glance over to where the little butter ball was recovering from the relatively light amount of exercise. Not that I could’ve done any better by any margin. But it was still under half her previous score. “8” Deena groaned out as she heaved her body up and I blinked a few times in shock. I had been far too hypnotized by all the rippling jiggling sweaty bodies to keep count. But that was more than her push up amounts and she had been having a far easier time with those in the first round. I had no intention of arguing with her though.

I readied the App and pointed the reticle down at the puffing and panting Gaia. Some part of me was vaguely aware that I was supposed to be studying. But that part was drowned by the sheer amount of pleasure I was feeling in playing one of my games. A pleasure only matched in size by the pounds I inflicted with the next push of my button. The full weight of her younger sisters efforts poured onto the shapely eldest's body and she blimped outwards with blubber. Her gut billowed a round orb of soft fat which began to compete with her short wing span. Her arms softened and expanded into soft pillows ill fit to lift much of anything. Leaving her top half decidedly round like a literal butter ball. Her bottom half however was a much more dramatic flair out in size. Her thighs thickened out and widened to a scale that would’ve matched her previous waspish waist. Her hips expanded outwards past hand holds into full blown arm rest jammers. But even they were mostly set dressing for the sheer mass that was her rear end. While my pale booty had it beat in sheer mass relative to her size her bottom was beyond impressive. Each cheek flaring out behind her in a perfecting unsagging round shape, each one big enough to look like it was half her body. Her figure looking more like a perfect sculpture of a fertility goddess, with its lack of cellulite and rolls. But there was nobody who could say she wasn’t an undeniable fat ass.

“Go...uh rest on the bench you two” The coach muttered gesturing at a thankfully mostly sturdy looking piece of furniture next to the gyms central ring. Her voice was loaded with such disappointment and disdain I almost changed target. But the thought was cut short as Deena started to struggle to get to her feet. A task which I soon found myself assisting in by giving her rear the old heave ho from behind. I was somewhat worried I’d lose a hand in her various rear rolls. Or worse yet she’d fall backwards on top of me, in what would be a rather sexual way to leave the mortal coil all things considered. “Thanks for your help, I know I kind of botched helping you study” she explained with a deadpan sigh as she waddled her way over to the bench. “It’s actually fine, to be honest, it was worth it just getting to marvel at how much drive you have in spite of being.... you know” I said gesturing at my hips and flaring outward. “Such a huge fat ass” she finished with an earthy chuckle. “It’s Gaia’s doing mostly, I’d be lazy and sit around on this couch of an ass if she wasn’t constantly nipping at my heels” The younger sister explained a flair of admiration in her voice. Rubbing her enormous rear absentmindedly and making it jiggle.

As we approached and I noticed Gaia following along after us. I became increasingly concerned for the bench's safety. It creaked and seemed to bend a little inward as Deena dropped her megaton ass onto its struggling surface. It let out an even more hearty protest and I felt it physically dip even further as my own rear added its considerable mass to the struggling wooden structure. So, as Gaia positioned herself to drop her perfectly shaped oversized booty onto it, I was fully expecting it the go the same way as the exercise ball. But while it suddenly lurched downwards at the impact and it seemed to be now inches from the floor, it held fast against our oversized bottom halves. Leaving me to try and socialize while completely sandwiched between the hips of the oversized sisters. Our rears pushing into one another as they drooped off the back of the bench behind us. “You don’t stand a chance this time, tubby” Gaia told Deena with a pouty glare on her plump lips. Still recovering from the workout. “Wrestling is a sport of size small fry, and I’m bigger than you in every way” Deena shot back with a dead pan confidence.

“That’s only because you have fat friends like her who’ll make you keep your lead” Gaia protested clutching my gut and sending it jiggling. "All my friends keep telling to me diet” she growled in a tone which was somewhere between jealousy and frustration. I really wasn’t sure if she was calling her sister fat as an insult, or if she was jealous her younger sibling had such a size advantage. “Come on by the standards of my friends, she’s barely chubby” Deena protested coming to my aid a little. “Oh yeah, but she’s definitely fat, I mean her ass is bigger than mine” Gaia explained and I winced preemptively knowing the ensuing spank was coming. Sure, enough there was a crack like a whip and I felt my ass ripple at the impact. It was the hardest I had ever been spanked, no doubt because of the muscles buried beneath Gaia’s thick exterior. “That’s just because you’re so tiny” Deena explained in her matter of fact sort of tone. Reaching over my head to give her elder sister some affectionate head pats. The following glare was downright murderous. Then in a motion warranting a noble prize I felt her slap my ass again, harder this time and on the side. And I let out a literal squeal. Yet Deena let out a grunt as well dropping a hand to the side of her own rear. With a glance I saw that her’s was wobbling almost as much as mine was. Gaia having effectively passed the momentum of her spank through two asses at once.

“No fighting outside the ring you two” the coach called from the ring itself and the two smiled aggressive smiles at one another. The duo proceeding to heave themselves up off the bench fast enough for me to feel it spring back up. The process getting me jiggling again. I was sort of shell shocked admittedly. Both because of how my rear had been abused and because of how I had been sandwiched between unquestionably two of the hottest rears I had created. Though even as scrambling for a sapient thought as I was. I knew one thing. The duo was about to have a practice match.
