The Key

When I unlock your unblinking regard  
It feels most disconcerting; so, I turn
My head to look away; you press in hard:
Your member's thick and rigid; and I learn
That, though my eyes are hidden, sadists see
The tears in them, reflected in the pain,
Caused by each push to duplicate the key  
That locks me into darkness, where your claim
Is staked with stab and jab and lunge and drive;
And push and ram and prod; you won't beguile
'til cock's withdrawn,  light's blocked and I survive
Your supercilious drawl, laconic smile,
And snide remark; this passion is the drink:
The poisoned chalice leading to the brink.
