The Last Constraint

She just doesn't seem to mind
All his desires, those that bind
She still entertains some fleeting hope
As he coils out the rope

He insists that she not fight
Even though the knots are tight
Her breasts bulge between constraints
Still she offers no complaints

But she can no longer feel safe
The strap between her legs begins to chafe
He may or may not get his fill
While she finds herself prepared to kill.
