Hinata Kiba nail

Looks like Naruto has some serious reason to worry - Hinata is going to fuck with Kiba! But that will happen only if you will complete the memory card minigame which you can play at three different settings of difficulty yet the basic rules will stay the same - a bunch of card will be mixed and you will need to open all matching pairs before the number of tries will expire (and this number will be defined by the difficulty level obviously). Overall nice and simple animated hook-up scene which might end with an awesome popshot... but once again - this will happen only if you will succesfully complete the minigame. By the way you can find a lot of other hentai parodies like this one here (but there will be other anime characters and other minigames ofcourse) on our website.
