The basic premise is that when Orochimaru puts the 5-element seal on Naruto in the Forest of Death, things go terribly wrong for him because he makes a mistaken assumption. This is a first draft with only spell checking done, so be warned.

Orochi's Oopsie.
<<Forest of Death>>
Orochimaru extended his tongue and entrapped the blond Jinchuuriki within its coils as he brought the struggling genin to hang before him with his seal-marked belly exposed. Orochimaru took his time as he prepared the 5-element seal and then slammed his glowing fingers into the seal in an attempt to cut off the raw power that was empowering the strengthening struggles of the trapped boy. Unfortunately for him, his attempt succeeded.
To be fair, even his own teacher and ex-teammate had failed to understand the true nature of the seal that Naruto had been burdened with since the day of his birth. The seal's creator, the Yondaime, had made great strides in the study of seals and had discovered a new approach to the problem of sealing Bijuu. Jiraya and Sarutobi, as well as much of the adult population of Konoha, had made a mistaken assumption about the nature of Naruto's abundant chakra.
The seal did siphon off a measure of the Kyuubi's chakra, but it didn't use it to bolster Naruto's chakra but instead to oppose it on a constant basis, forcing it to grow ever stronger in response. Naruto's problems with control were due as much to the ever changing flux of this constant battle as the size of his reserves. Indeed, the vast majority of Naruto's chakra was locked away within the seal in constant battle with the Kyuubi's chakra.
Until now when the addition of Orochimaru's 5-element seal caused all the Kyuubi's chakra to be locked away. The vast majority of Naruto's chakra that had never been sensed by anyone now surged out of the seal in a vast wave of azure power.
Under normal circumstances, Orochimaru would have been able to survive the results. If he had any idea of the true nature of what he was doing, he would have placed safeguards beforehand. If he had been even 5 feet away, his reflexes would have gotten him away with survivable injuries.
But he was in physical contact with the seal through his fingers and his tongue was wrapped around Naruto's body as the seal released Naruto's hidden chakra with such force and speed that it raced up Orochimaru's chakra network faster than his nervous system could transmit the signal. The small percentage of Wind natured chakra that was part and parcel of Naruto's unique chakra signature (which is what chakra paper responded to) sliced apart the nerve cells before they could even transmit a signal to the next in line. Orochimaru literally never felt a thing as he was reduced to a thin red mist on the forefront of the chakra explosion.
Naruto himself was unharmed as his body was already attuned to his chakra, although all of his clothing and equipment was shredded apart on an almost molecular level. As for his team mates, they too were rendered naked and were slammed into several trees. The only reason that they would survive would be the fact that they had been marked by Naruto's chakra during their mission to Wave. They also avoided major injury from impact with the trees because the trees themselves were being reduced to sawdust by Naruto's chakra at the time of the impact.
The initial wave of erupting chakra formed an azure dome over a half a mile across before dissipating, leaving a clearing that was scoured down to bedrock with all the debris being blasted throughout the forest and even beyond it's boundaries. The unbelievably fine chakra charged dust formed from the obliterated trees, soil, and stone of the cleared area caused respiratory distress for all the occupants of the forest below high Jonin level as only they had the power and skill to protect their lungs from it.
The Exam was cut short as medical teams rushed in to rescue the afflicted teams and proctors. The Sandaime himself arrived first at the flat bottomed crater for he had recognized the chakra signature of the explosion as Naruto's. The discovery of the naked forms of Sasuke and Sakura at the edges of the crater only heightened his worry as he made his way to the column of swirling azure energy that continued to rise at the center. He could make out Naruto's form within the column as he floated within it, gently turning in place. The seal on his belly stood out in contrast as it was glowing a soft red color instead of the flat black it normally displayed when Naruto was channeling chakra.
Sarutobi took a deep breath in shock as he made out the 5 foreign seals that were glowing a diseased purple. He recognized the 5-element seal and the signature of the chakra that had formed it. His rogue student had been here and had attempted to prevent Naruto from using the Kyuubi's chakra. He gave orders for ANBU to summon more squads to hunt for Orochimaru while he weighed his options.
Although he would prefer to have Jiraya release the seal, there was no time to wait. He ordered everyone else back as he prepared the 5-element seal release and plunged his hand through the pillar of Naruto's chakra, accepting the damage it did to his hands and arms in order to remove the tainted seal.
Naruto's chakra withdrew into his body and Sarutobi barely managed to catch his collapsing form before he hit the bedrock below. Sarutobi gave out a sigh of relief as he registered Naruto's continued breathing and pulse. He laid down Naruto's unconscious form in order to get treatment for the bleeding cuts on his hands and arms that he had gained from his brief exposure to Naruto's runaway chakra.
The relief was cut short as a recognizable sense of killing intent began to emanate from Naruto's prone body just before a pillar of red chakra emerged, causing Sarutobi to retreat in shock. He could see the face of the Kyuubi forming in the swirls of red chakra as it seemed to scrabble to get away from Naruto's body. But the red chakra was being pulled back and an unearthly wail of anger and pain was heard across Konoha as the struggling Kyuubi was dragged back into its prison.

As for when Naruto seems to draw on the Kyuubi's chakra: If he starts to deplete his ready reserve (the chakra outside the seal), the seal transfers a portion of the Kyuubi's chakra to the other side to keep the balance even. This allows the Kyuubi's chakra to mix with Naruto's and causes the physical changes to occur.
What do you all think? Edited with some fixes after I got some sleep.
