The screen blinked, and then an icon appeared that said, "Thank you. Your request is being processed."
Almost immediately, Ben writhed on his bed, as his whole body felt like it was on fire. His head felt like someone was drilling holes in it, while his chest felt like every bone in it was breaking at once. His legs, conversely, felt like they were melting in boiling acid.
Ben tried to scream from the sheer agony his body was going through, but his vocal chords wouldn't respond to his mental anquish.
He watched himself helplessly in the mirror as he contorted in pain. He forced his eyes open, even though they wanted to clamp tightly shut. He saw his torso jerk sharply back and heard a loud crack as spine was broken and bent into a 90 degree angle. Through tears of agony, he watched his chest swell with disgusting red growths--- dozens of overripe tomatoes were growing underneath his skin. His legs looked like a zipper were running down the middle, and felt like a chainsaw was ripping through the seems. Each half-leg appeared to be a bloody open gash with muscle and bone exposed, like something out of a civil war drama.
He cried out loud as they split apart. His butt began to swell and erupt with painful spasms--- enormous black sacks of puss started to emerge, tearing his boxers, leaving them fogotten on the floor below.
His scream was cut short as he watched what looked like hundreds of tiny ants crawl underneath the taught skin of his horror stricken face, while two giant centipedes crawled up from his shoulders, up his face and behind his eyeballs.
Ben prayed that he would pass out, or that someone would come put him out of his misery, but he couldn't help but watch as his transformation progressed. Now he couldn't shut his eyes, even if he wanted to.
The ants coalesced around his mouth and ripped through the surface, forming the goatee that he add asked for. The black sacks of puss that used to be his prized "bubble butt" continued to expand, taking two of the leg-halves as they pushed backwards. The half-legs each filled in, however, and the pussbags melded together, forming the smooth, black-furred trunk of a powerful stallion. Each leg remained human shaped, with coarse, jet black running down to the ankle, and four beautifully large feet at the ends. A sharp pang accented the torturous expanse of the lower body, as a black tail emerged from above his new, capacious ass-cheeks.
In a near-blinding burst of pain, the tomato pustules broke, swelling his chest to mammoth proportions. Four splintered points of broken ribs shot out through his sides, quickly wrapping themselves in sinew and flesh, as the new arms grew to be clones of the first two, all six of them thicker and more powerful than before.
Finally, the two centipedes which were lurking behind his eyeballs, causing frighting twitches of pain each time they moved one of their hundred legs, chewed their way out of his brain case, gnawing through bone until they emerged into the light, bending back on themselves before hardening into gleaming ebony goat horns.
Then, as quickly as it had started, the pain was gone, and the icon on the computer screen read, "Transformation completed. Thank you for choosing Major Changes."
Still in shock over what just happened, Ben inspected his new body...
