Chapter 142 - #142 /the competitive effect/

“How about you let me use my phone between sets?” I suggested to Deena who was still struggling to heave herself into some more press ups “Uh, I wasn’t planning on stopping you, but I guess that works” She replied between slightly dragged panting breaths. The sweaty blob of a girl struggling to heave her enormity up and down even with the greater ease granted by her bed of a gut. I couldn’t tell if she was being sarcastic in light of her dead pan personality. But I didn't mind either way, my attention was fully focused together on putting a game together. On deciphering the elements I’d use to pull all the entertainment I could out of bringing the smaller sibling up to size. The only element I was sure I wanted to incorporate was the ongoing rivalry between the short and stout eldest and the tall and titanic youngest. As she completed another push up and grunted out the number seven, it struck me. I had a fluctuating numeric value, and a skill test to pay it off. All the ingredients needed for one of my patented games. For every successful motion Deena performed, I’d add 10 for every successful question from me I’d add 5.

“Back to sit ups” Coach called from off side and Gaia let out a tiny squeak as she was pulled from her obsessive rapture. Returning to the mat and assuming her optimum setup in no time flat. Swinging her muscular yet compact frame from lying back to sitting in a series of clockwork motions. Deena meanwhile once more required my help getting from her front to her back. This time I assisted by heaving her gut up while she maneuvered herself into a sitting position. Before finally lying back for me to grab her flabby shins. If it had been mere minutes prior, I would’ve been melancholy at losing the view of her rear and reassuring myself at the thoughts of how good a view it was for her gut. But with a game afoot I had my eyes on an entirely different prize. “So, Gaia’s kind of competitive?” I asked stating the obvious for no other reason than to ease some of the tension at my anticipation building. “Yeah she used to race me down the stairs to see who could eat breakfast first” Deena shot back with her usual deadpan countenance. In spite of the grunting and sweating that every failed sit up caused her, she maintained a surprising strength of dignity about her. Impressive given her mountainously obese form. “Speaking of breakfast what French breakfast food did we cover as a case study again?” she mused aloud. The question catching me off guard.

Obviously, she wasn’t easy to distract with family questions. Between my anticipation to see her do a successful sit up and the effect her body had on my degenerate brain, she had to provide me with the answer again. Though as she finally completed a sit up and asked the question again, I delivered the answer in full. Earning me a couple more lbs of flab to load onto Gaia’s muscular figure. The girls form was as perfect and robotic as ever. As Deena completed her second sit up my anticipation was building. And the massive womans rippling motions of heft were so enrapturing I actually found myself paying attention to her battery of questions. Every correct answer earned more flab for Gaia's figure. With a frame as short as hers every pound was all the more apparent. The only real problem was that the anticipation of actually inflicting all that blubber was more than a little distracting. A mental war between the day dream of Gaia thickening and the very real enormity of Deena waged for my attention.

“You don’t seem all that competitive yourself” I managed to squeak out. An attempt to buy myself time between questions to right my head a little. “Well I guess not, at least not with most people” Deena muttered mid grunt. Yet inspite of herself I noticed her complete the sit up with quite a bit less difficulty than before. Sucking her gut in to ease the task for herself a little more. Given the sheer amount of sweat and the difficulty her girth presented to exercise I doubted she was sandbagging. Which would’ve made the surge in ability a bit confusing if I wasn’t too horny to care. “For example, I tend to avoid competing when it comes to things I’m not good at, like cooking spicy foods...” she started to grunt out obviously mentally stretching to find an easy way to roundabout to the question. “Our Southern American case study was Tortas” I answered off the top of my head chuckling a little to myself. My immediate answer earned me an eyebrow raise, probably due to the fact it was the first answer she hadn’t had to give me first. It wasn’t just because I was motivated either. Eliza had been a total slut for those things when we were making them and I had managed to sneak a couple of pounds worth of them onto her figure before she noticed. She paid me back by exploiting my ice cream weakness when summer came around though, and she came out relatively ahead in our little skirmishes.

Any further comment was interrupted by a blown whistle from the coach, obviously calling for the girls to switch back to push ups. While most other gym related whistles had inspired fear in my nerdy heart this one ignited it with a warm glow of joy, along with my loins. “You’ve got...30 seconds” Deena explained dead pan as she attempted to get back onto her front. Rather than help her out I was too busy targeting her sister with L.B.L Up. My brain hastily doing calculations to factor in just how much mass I was going to pour onto the stout woman’s frame. 3 correct answers from me was 15bls, plus 3 sit ups from Deena meant 45lbs of blubber total. By the time the thought had fully factored into my brain Gaia was already in position to set into her first push up. Arms spaced perfectly apart, back muscles rippling with tension, powerful thighs gapless but obviously strong. Perfect form to match a perfect figure. With a tap of my button I ruined both. A flicker of blue runes on L.B.L Ups screen as she began to expand right before my eyes.

Instantly muscle definition was the first to go. While the powerful muscles were still there keeping shape to her mass the lard was too much for even her gym rat figure to survive. Soft dark flesh jiggled into view and expanded all the more dramatically given her relative size. Muscular arms became slightly soft looking. Powerful thighs grew larger and more cylindrical as they pushed each other and thus her stance apart. Like an actual photographer I had chosen the ideal moment to soften her form so that rather than a hovering core of rippling six pack muscles, a slightly hanging paunch touched the mat at her first push up. Yet as if pre-ordained by destiny there was one part of her figure which thickened the most. Her bottom half went from sculpted blocks of dark muscle to jiggly caramel pies. Softening and rounding out into soft perfect spheres of a dramatic size. Yet I couldn’t help but feel a little frustrated at the sight. Even blown up with extra poundage her preexisting muscular and good genetics meant she still looked amazing. She was thicker to be certain, but none of it was saggy or flabby. Looking closer to a body positivity Instagram model than the out of shape former athlete I had hoped to create.

Though while her figure was mostly intact her form was clearly thrown off by the extra flab on her once spotless figure. Her motions were decidedly less powerful, her form less untouchably perfect. I could almost hear her starting to breath a little bit. Yet she wasn’t the only one experiencing a change in form. From the crest of the hills created by Deena’s enormous ass I could see her form shifting. Her grunts were becoming less prevalent and somehow more rhythmic. I could see in the waves that rippled across the hills of her rear. Her spare words now used only to keep count rather than to coach me. She was still the same size, still as humungous in girth. There was nothing that was going to make lifting a megaton ass like hers easy. Yet she was certainly going faster. Even as Gaia slowed down, I could see her pick up again with a grunt of her own. There was still a full digit worth of difference between them. But I could feel it in the air, they were actually competing.

As the coach blew the whistle again, I snapped back to reality. Obviously, they were to go back to sit ups yet again. I blinked a few times, realizing that I had actually lost count of how many pushups Deena had pulled off. Though judging by the sweaty gelatinous heap of blubber beached in front of me I would’ve wagered it was higher than I was thinking. “8” she grunted as she finished her final one. I couldn’t help but let out a slightly surprised yelp. Both out of admiration for her athletic tenacity in the face of such heavily weighted odds, and at the penalty Gaia would face. I readied L.B.L UP once more and centered it’s targeting reticle. The tiny powerhouse still hadn’t broken a sweat, but she hadn't made it the fifty mark she had so casually broached before. I could only imagine what an extra girth infusion of such magniture would do to her form. Thankfully I didn't actually have to imagine at all.

A tap of a button made my fantasy come alive. With such a large infusion it poured on suddenly and mercilessly. Her body expanding out in every direction. Her waist softening and widening as a full-blown gut expanded into the gap between her middle and the floor. Her hips of course outdid them by a margin. Coming into a familiar pear shape as they widened into easy hand holds, forming jiggly saddle bags. Though what was beside them grew the most. Blowing outwards into round watermelon sized cheeks that somehow maintained a frustratingly round succulent shape. In fact, even with enough mass to make her certifiably chubby her flab retained that perfect gravity unaffected shape. Though nobody would’ve guessed her to be a star athlete. There was no denying her body was still pretty much perfect. Even as big as I had made it.
