He freaks the fuck out.

"WHAT THE ABSOLUTE FUCK!?" a feminine voice roared out, and causing the base in the middle of nowhere to shake. Just two minutes earlier, Sasuke had gotten up, and not initially noticing anything amiss in his slightly groggy state, had gone to the room with the showers... And then he had started to undress...

Needless to say, the whole base was wide awake after that outburst, and Kabuto burst into the room, chakra scalpels at the ready. He then blinked, seeing Sasuke topless... And with long hair and boobs... What? "Um... Sasuke... What's with that Henge?"

"This isn't a Henge, you should be able to see through those from a mile away..." Sasuke hissed.

"...so... You just woke up as a girl then?" Kabuto asked, and Sasuke grit his teeth and nodded. "...you do realize I can see your tits like this right?" Kabuto asked with an amused smirk, readjusting his glasses, before paling drastically as a Chidori Sharp Spear pierced the wall next to his head.

Sasuke, one arm outstretched for the jutsu, the other now wrapped around his... Or was it her, new bust, snarled, "Get. Orochimaru."

Kabuto gulped and nodded, cursing his mouth. Sasuke was all too easy to piss off at the best of times, and adding female hormones to the mix... Yeah, he needed to be extra careful around the guy... Girl, whatever! Especially if this new form was permanent, and included periods... Kabuto shuddered at the thought, not wanting to be anywhere NEAR the Uchiha if that happened, especially considering Sasuke would have no fucking clue how to deal with such a state, considering he grew up as a guy.

Sasuke meanwhile seethed, retracting the jutsu. Frankly, if he didn't know better, he'd think Naruto was behind this somehow. The blonde idiot had been swapping his own gender with that idiotic Sexy Jutsu of his for ages, though Sasuke had to admit it could be stupidly effective against perverts, and he would not be surprised if Naruto had found some way to cause it to happen to others too.

(Lol, you have no idea how close to the truth you are there Sasuke... Is it weird I was laughing my ass off the whole time I was writing this?

Anywho, here's what Sasuke looks like as a chick:
