EXECRETED ALIVE

Eaten alive
Munched into pulp
Premature necropsy
Comes closer with each gulp

Brain not fully dead
Decrepit splattered limbs
Mass ensanguined spasms
Excretion now begins...

...Semi-conscious human faeces
...Simi-digested squirming pieces
...Semi-animate in excrement
...Semi-terminal constipation

(Solo: pulsating sphincter)
