Nice poetry here - it's a short piece but full of oopmh and feeling, I get the impression the immunity of the monster compells the narrator to accept their body and accept the toxic that has entered them... good imagery and I definitely feel the anxiety as well as the rumbling pain from this piece!
Great stuff! it's inspired me to write my own poetry! In fact, looks like you've inspired me - my next songs will be poetry and spoken word based!
