Kyle groaned as his legs began to feel strange. An intense heat flowed through them, burning as they began to change. Bones cracked and reformed, and his muscles twitched and spasmed under his skin. He watched in horror as his feet reformed into canine paws, fur sprouting on them. His skin itched as the fur traveled upwards, reaching his navel. He gulped as he felt his genitalia shift and change, becoming a huge horsecock hidden in a canid sheath. A bizarre pulling sensation yanked on his tailbone as his tail pushed out behind him, pinned between his torso and the bed.
The transformation paused for a moment, giving Kyle precious seconds to take in what had happened. Concerningly, the heat in his legs had only become more intense. He shifted. pulling his tail out from behind him as he felt his huge equine balls slide against his furry thighs. Looking down, his legs were the sane size they were before, only they were the digitigrade legs of a dog. They were covered in tan fur, with white fur spreading over his belly. They ended in large paws, complete with pawpads and claws. He felt his new cock stir in its sheath.
He shuddered as a new wave of sensations washed over his legs. It felt like they were... filling up? Like something was being pumped into them.
And that something was lard.
He watched in horror as his new legs began to expand, inch upon inch and pound after pound pouring onto his new legs. His hips pushed out, and his back was lifted off of the bed behind him as his ass expanded. His legs quickly softened, becoming nothing more than huge jiggly masses. His bed creaked beneath him as his lower half got larger and larger, soon entering hyper territory. When it slowed, and finally stopped, Kyle found himself atop a huge mass of flesh.
His ass spread out 7 feet wide, and his thighs matched. He felt the edges of his thighs pull heavily on his skin as they hung off the sides of his bed. His ass wedged itself between his bedframe his torso, his tail squished into it. His calves alone were larger than his whole upper body, and his knees were as wide as his shoulders. His paws were lifted off of the bed by the largest cankles he'd ever seen. He felt folds and lumps of fat bunched up uncomfortably beneath him, but he was unable to shift his weight by himself.
He ran his fingers through his soft fur, and felt his hand press into his soft flesh. It was his dream, attached to him, but it felt like a living nightmare. Kyle secretly adored fatfurs, but he never wanted to be one. He wanted to be the one crushed underneath, not doing the crushing! It just didn't feel real, his scrawny little body abruptly transitioning into a bed-sized mass of furry flesh...
