Maggots in the anal tract

there's an itching feeling in your anal tract
feels like a swarm of flies
it aches from your stomach to your ass
this terrible rumbling in your bowel

your excrements, it seems they're movin'
a mixture of shit, pus, blood and there's something small that's movin'
you haven't seen movin' shit before

in fact your anal tract is full of maggots
they were creeping out of your closet straight in your hole
a few hours ago they started their destructive work
you'll be eating from inside your bowel, only mangled guts

now your whole intestines are gnawn to pieces
thousands of those cute and nice creatures
blood, pus and guts are flowing out of your bowel
