A dicey mistress

I have to forget her  
A demanding mistress  
With her misty dust-laden cover  
Duping my naive senses  
I crave to rhyme  
Risking my future  
Engineer's passion crime  
Drowning his investor  
Chemical technology  
Mourns lack of attention  
Semesters demand apology  
Signalling dire repercussion  
Shut you from my brain  
Block you in my browser  
Poetry, you still won't refrain  
From itching in my trouser.
