The Growth Spurt

Allie's eyes shot open. She screamed. She shook. Her whole body seemed ready to come apart at any moment.

"What...is...happening to me!?"

A moment later, a sickening cracking noise filled the air. Allie howled in pure agony as her bones snapped and reformed.

Lynn looked on in horror at the quivering teenage girl. Something was happening, something horrible. She could hardly believe her eyes.

Against all reason, Allie's arms and legs began to stretch like rubber. Her ankles peeked out from the bottoms of her jeans, followed closely by the pale skin of her calves. Likewise, her arms like white eels surged out of the caves of her sweater sleeves.

"It burns! It burns! Oh God, make it stop! I'm going to die!"

Allie's clothes tightened against her growing skeleton. Her sneakers strained as her swelling feet rapidly outgrew them.

Allie lifted onto all fours and vomited, spewing her dinner onto the carpet beneath her. The acrid smell of bile attacked Lynn's nose, but she did not look away. She could not. The horrible metamorphosis captivated her completely.

The girl was suddenly on her feet, stumbling about in the ruined bedroom. She was much taller now. Whereas before, Lynn had stood several inches above her, now Allie overshadowed her.

The fabric of Allie's sweater and jean tore slightly as skeleton finished its transformation. By now, Allie stood taller than most men, around six and a half feet by Lynn's estimate. The pudgy little teen was nowhere to be found. This Allison was tall and gangly. Her body was thin to the point of emaciation. This, however, was about to change.

"Is, ugh, it, ngh, over?"

Allie had no sooner said these words before she doubled over again in fresh agony. She cupped her chest and sobbed. Her unremarkable breasts were now borderline invisible on her stretched frame. Lynn would have pitied the girl if they had stayed like that. Instead, she watched in amazement as the little mounds of flesh began bulge between Allie's fingers. They grew in ragged bursts, getting bigger and shapelier with each surge.

"Oh," the boobs were now bigger than Allie's extended handful.

"My," they grew as big as Lynn's.

"God!" the sweater ripped further, strained to its limit by the combination of growing bone and boob flesh.

Allie's tits were now supernaturally buoyant. They bounced and quivered with the tautness of small breasts and the heft of ripe milkers. Allie's ruined bra tumbled to the floor in a heap.

"My...boobs?! Ugh, no, no more!"

Allie's body ignored her pleas. A final transformation was washing over her, one more significant than any she had yet endured. The girl stared down at her arms as fresh pain hit her.

"No! No not that! Not...ugh!"

Lynn watched in shock as Allie's body rapidly filled out. Her skeletal frame surged with muscle. Her biceps and triceps swelled against each other like a beefy yin-yang. Her shoulders turned to boulders. Her clothes were hopeless, shredding apart from her growing strength. Allie howled, her sparkling high-pitch voice deepening into a husky groan.

Then it was over. The room fell into eerie silence.
