I love how it's been up here for 14 hours and hasn't been hidden, not that I really care though.
It's based off the characters from K-On if you didn't know. That's what makes it funny.
Well damn, that's just gonna make K-On that much less enjoyable because that sick piece of crap will be stuck in my head... (This is why I don't watch hentai. For me, it makes anime disgusting.)
^ I doubt it will make K-On less enjoyable.
I don't really watch hentai either, but it doesn't make sense how watching it would make anime disgusting. Does watching real life you-know-what make you find Hollywood movies disgusting? It's the same concept really.
