A Fundamental Question (Quatrain)

She asks him this and that to exercise  
Her tongue, finding answers to help her face  
The world; now let her face up to surprise,  
When sir insists her tongue must learn with grace:  
   
So let it grace sir's arse: a thing for whores  
To love and lick and pleasure for a time;  
She'll forget her reserve and all the mores  
That made her hold from doing this; a crime?  
   
Her crime would be to fail to please, she slakes  
Her thirst around the hole that others shun;  
She'll kiss and lick, until her master wakes  
And has her carry on as she's begun;  
   
Build up his appetites with more ingestion  
Of tongue; swirl it in response to this task;    
And he will pose the fundamental question:  
She's learned to rim; so what more can she ask?
