First story. But hey, i like writing, you like reading, win win.
Anyone who doesn't like billdip FUQ urself, and read anyway
Also, has some smut (but also fluff) and a little bit of CARNAGE!

Bill is trapped. Always has been. His mental problems, his right eye, his horrible taste... And his craving for blood. All of it, but what happens when this psychopath is forced into being tutored by none other than Dipper. A cute brunette nerd who is always with his twin sister Mabel.
Will there relationship live on? Or die?
