The powder in the tub was already nearly gone; Isaac had become practically addicted to the delicious beverage; despite this fact, he had only been to the gym three times in as many weeks, and the last time he had gone he had stayed in the locker room, too embarrassed to work out in his gym clothes.
Isaac now stood in his bedroom, attempting to fasten what had once been the bag first jeans he owned; they now appeared to be painted onto his thighs, and the waistband cut mercilessly into his midsection as a small layer of chub gently oozed up and out of them.
Fembulk had certainly lived up to its name--he had bulked up in the last few weeks, but it was anything but muscle. In fact, Isaac was sure he had rapidly been losing weight. Although he had been quite slim, Isaac had always had a V shape, with broad shoulders tapering down into a well toned torso, but now his shoulders had withered and, standing here without a shirt on, they appeared quite rounded and soft, instead of the jagged, firm ones he was used to. The V had now practically completely disappeared, and, although his torso still tapered in towards his waist, it had inexplicably begun to flare outwards starting at his navel and continuing into his hips, giving him a shape much closer to an X instead of a V.
The scale that morning had read twenty pounds heavier than it had three weeks ago. And while twenty pounds was not, on the surface, an incredible amount of weight for his slim frame, the facts that he had lost a significant amount of muscle and the added weight was purely fat, made it much more pronounced. Even more disturbing was how the weight had distributed itself, settling almost exclusively in and around his hips, thighs, and buttocks. He had, previously, had a stereotypically flat bottom, accompanied by slim, lean muscled legs. Those were gone now, cocooned in a not insignificant layer of fat, which now caused his burgeoning booty to pop quite a bit more than he was used to. It was on the verge of becoming a bubble, at this stage, and was the most disconcerting development in his opinion this far. His thighs, meanwhile, had practically exploded in size, giving them a soft, feminine taper down to his once bony knees, now also softened, and creased considerably now in the back. Further along down his legs, his calves had lost their heart shaped muscling, and hardly tapered at all as they made their way down to his increasingly chubby ankles. His hips, meanwhile, flared out dramatically, now, practically matching the width of his dwindling shoulders. Other areas had not been neglected by this sudden change; where once his firm abs had been, a small, puffy pooch now sloped outwards, flanked by two small, but developing love handles. Further north, where his pectorals had been, was now puffy, and had no semblance of firmness about them. His arms had lost their tone, but ha seemingly remained the same size, if not slightly bigger. The sleeves of his fitted t-shirts had begun to sink into them with little resistance, squeezing them tightly. His face was also changed dramatically. The sharp angles had been replaced by rounded lines. His jawline had softened, and his cheeks had inflated slightly, giving him the flight appearance of dimples when he smiled. His eyes, too, seemed bigger, and his nose somehow smaller.
Finally, Isaac wrestled the too tight jeans off from his legs, and settled on the pair of sweatpants he had found himself wearing more and more often--although even these were becoming snug, and his prominent behind pressed up against the fabric conspicuously, and looked considerably feminine when viewed from the rear. He pulled on one of his remaining baggy t-shirts, and made his way to the kitchen, a place he found himself more and more often.
Maybe it was time for him to go shopping, he thought. Or had he just heard a knock at his door?
