Open the Anus

At one morning I woke up 
With strange feeling in ass 
One meter of wood 
Was plugged in my anus 

Gallons of shit 
Inside my body 
Painfully looking 
An way to get out 

Open the anus 

Pressure grows 
You cannot withstand 
Trying to excrete 
Oh, it wont come out 

Shit happens now 
Your limbs separate 
Without arms and legs 
Your head is full of shit
