Is there something I'm missing? How is this rape? How can you be sure there is any sex happening at all? It just looks like Hinata preparing to kiss a very embarassed Naruto.
His teeth don't really seem to be all that clenched, and his eyes are wide because he is surprised that Hinata is about to kiss him. Sorry to ruin your fun, but unless I am missing something, there is no rape going on in this picture. At most this picture could be tagged with "you_gonna_get_raped". I'll refrain from changing the tags for now, just in case.
