Okay.. back to the title..

Adult version of Naruto?? Naruto probably be using his sexy jutsu more often to seduce hot bloody emeny ninjas.

Gaara's Big Sandy Demon be raping Sakura. (Like in BErserk).

Jiraiya would be doing the nasties more often than being an unfortunate loser right now.

And.. Naruto and Sakura+Ino+Hinata would be having a 100some orgy.

Oh yeah.. Batttles would be definitely more violent. With Kunais going right through bodies and heads with organs and brains flying evverywhere.
