Role Reversal

Her Master has her well contained
Stashed in an ancient antique box  
Her patience is becoming strained  
And she contrives to pick the locks  
  
So this time she just won't submit  
And then seizes the upper hand  
No quarter 'cause her fuse is lit  
And it's high time she took a stand  
   
She straps him down upon the bed  
And soon climbs on his stiffened cock  
Safe word recalled, but nothing said  
Since she stays disinclined to talk.
