Kiba smacked his lips and wrinkled his nose as the chemical fizzled all the way down his throat and into his stomach. The very second the strange concoction pooled in his stomach, Kiba felt his whole body begin to tingle, as though he was filled from head to toe with fizz. He twitched as he felt this sensation coursing through his body, making him feel completely numb. Just as he was about to fall to his knees, the fizzing sensation disappeared, replaced with a very different feeling. A strange warmth was now coursing through his body, making the dog ninja sweat, his breathing increasing as he began to heat up, sweat beading on his forehead. He pulled on his collar to relieve some of the heat when he caught something strange out of the corner of his eye. His arm...looked like it was growing! Kiba's attention immediately snapped to his right arm, his eyes widening as he saw his forearm slowly thickening, a huge bulge traveling slowly up his arm. The sight of such a strange lump made Kiba's heart pound in horror before he realized that, whatever it was, it was causing his body to grow! The bulge traveled from his now thick forearm up into his bicep, the muscle suddenly bursting through his sleeve, covered in veins, at least the size of a softball! Kiba whooped in happiness as he saw this, the bulge now moving up into his shoulder which likewise bulged outward, decimating what was left of his right sleeve. Kiba flexed his arm, the bicep bulging even bigger, the veins mostly subsiding except for a single one running over his split peak. Kiba could swear the muscle was still steadily growing, even as the bulge move down into his right pec, the muscle exploding out of his shirt, his nipple hard from the experience and the sudden exposure to the cold air. "This is unreal!" Kiba shouted, his left pec popping out to match his right. Before Kiba could begin to explore his now massive chest, the muscles jutting out powerfully in front of him, the bulge started picking up speed, splitting into two smaller bulges, one moving into his left shoulder, down his left arm, and disappearing at his wrist, causing his left arm to explode out of his sleeve, mirroring the right. The other bulge passed by Kiba's neck, thickening it before passing down into his back, causing it to flare out, completely annihilating any material that was left of his shirt.

Kiba, now feeling a bit top heavy, fell forward onto his hands, kneeling in an ape like posture as the bulge split at his waist once more, this time into three bulges, one of which made a short trip into his crotch, expanding his dick until the button on his pants burst, the zipper wilting under the pressure shortly thereafter, his balls swelling to keep up the pace with his dick. The other two bulges moved down his legs, his thighs suddenly bursting through his pants, rubbing together as his calves exploded out next, shredding his pants entirely, leaving him in nothing more than a tight pair of briefs, the waistband cutting into his skin, the front side bulging out obscenely while the back rode up slightly, showing off his muscular ass. Lastly, with all the bulges now gone, Kiba's hands, feet, and head slowly grew to match the proportions of his body, leaving him with a perfectly symmetrical body. Slowly, Kiba got to hiss feet again...and hit his head on the seven foot ceiling!

With an amazed expression on his face, Kiba looked over his body, flexing his arm again. While he had been distracted with the other parts of his growing body, his softball sized biceps had pumped up to far greater sizes, his whole body pulsating with thick, powerful slabs of muscle, his once flat stomach bulging out in a tight six pack. "Oh man...wait until Naruto gets a load of me now! He's going to piss his pants!"

Kiba was still admiring his body when Shikamaru arrived back in the viewing room, glancing casually into the experiment room to see how Kiba was doing. He spat out the soda he had been drinking, staring in total shock at the behemoth that Kiba had begun. Slamming his hand down on the button he shouted, "Kiba! What the hell happened to you?"

Kiba put his hands on his hips and bounced his pecs cockily, grinning at the window where Shikamaru's surprised face could be seen. "Just testing that new medicine like I said I would!" He said arrogantly, slowly striding over to the window. His every step caused the floor to vibrate, not used to supporting such a colossal weight. Kiba bent down when he reached the window, smirking at Shikamaru who instinctively backed away. "Hey! Get in here and take some measurements! I want to know exactly how huge I am!"

Shikamaru gulped, wondering if it would be wise to defy Kiba. The lazy ninja certainly didn't want to go anywhere near the tower of muscle that Kiba had become but staying away seemed equally hazardous. What should he do?
