Corseting

yeah, i think it's about brutally murdering a someone, by shooting them in the face,

"I'm tying you up, using the nicest lace, trying to kill you softly, trying to erase your face. "

and blowing their brains out,

"I'd redecorate the walls with your inner thoughts, but I'm afraid it's the wrong shade of red."

making sure there no evidence

"All the while, I'm doing my best not to rub my love against your head. "

hm, maybe?
