You all know by now that I'm... specialized in short stories. Well, here is my latest one - another gun!kink story, which you can find in Storm Moon Press' anthology Weight of a Gun II
Cole Beauchamp is the greatest pistoleer of all time; he's also thoroughly unpleasant and has a habit of scaring away his assistants.

When he stilled, a cloud of smoke lingered in the tent, seeping slowly from the crack left by the tent flap. Benjamin closed his eyes and inhaled it greedily, loving the sharp tang of it on his tongue. He opened them again, and saw— Saw that the man was staring at him, eyes black and gleaming, just like the gun now aimed at Benjamin's face.
