The jutsu works (Body Swap)

It happened so quickly. Naruto's world went black, and his chakra seemed to leave him all at once. He felt heavy as stone, and then light as a feather. It was as though he was being pulled, tossed and turned through time and space.

Then...everything was still.

Naruto slowly opened his eyes, and as he rubbed the blur out of them he realized he was on the opposite side of the room from where he was--behind the Hokage's desk.

No way...

He looked down, only now realizing how different his body felt--and for good reason. Tsunade's enormous boobs were staring him in the face, her blonde hair running down the front of his shoulders, overtop her typical grey shirt and green haori.

His heart skipped a beat as he got to his feet. "No way...it works!" Naruto couldn't help his hands from going to his new breasts and giving them a little squeeze. He felt a tiny jolt run through his body. "Woah..."

He turned around, looked at the window to try and catch his reflection, and there it was: Tsunade's face staring back at him in the glass. Naruto looked back down at himself, tried to take it all in. None of it felt real. The boobs were one thing, sure, but everything was different. His centre of gravity, his muscles, even the heels he was now wearing. Despite all the changes, though, Naruto couldn't help but smile victoriously. "Alright! I did it!" he cheered.

"Lady Tsunade!"

Shizune's voice brought him back to reality, as he noticed she had moved to the other side of the room, standing over something on the floor--his own body. "What happened, Lady Tsunade?" Shizune asked. "Are you alright? You and Naruto both fainted out of nowhere, and he's not waking up!"

Naruto took a few steps around the Hokage's desk--harder than he imagined in heels--and stared in wonder at his own body. It was strange seeing it from this perspective, but given his new sensations--especially the two big ones on his chest--he couldn't help but be strangely excited by the whole situation.

Still, as he watched Shizune start to perform medical ninjutsu on his body, he began to wonder if he had made a mistake in casting the jutsu. Maybe he just woke up faster than Tsunade in his body, but what if he messed it up somehow?
