Sestet Challenge: Blocking the Knocking.

Locking myself , head bowed, in time to the knocking;
Knocking of your calloused knuckles on my rib cage, locking,
Blocking the darts aimed at my face, defense wounds shocking,
shocking to the mind. An assault coupled with flailing attempts at blocking.
Bleed with me, huddled over my own heart to protect it from your need;
Need to savagely destroy what is not yours, your need, to see me bleed.
