Now, the nonsense that originated from my brain:

GunxJohn

I barely repress a quiver as John cocks me and the smooth metal bullet slides into my chamber. John's running jostles me but the warmth of his palm against my grip and my utter joy at being used again rendering it barely noticeable. We slam through a door and skid to a halt as John finds our new flatmate.. in the opposite building. I know what this means and this time an excited shiver shakes my firing pin. His fingers tighten as he raises me and caresses my trigger. I stifle the lewd noises I want to make because of the excruciatingly pleasurable touch on my most sensitive part. There is no trembling from John like the previous times he's picked me up and the little bit of light filtering through the windows flashes off of me as that fact ads to my ecstasy. I feel the slight change as John's cautiousness turns into determination and there's almost no time to prepare myself before he squeezes. I scream as warmth runs through my barrel and I release the bullet, taking note of the satisfying sound of shattering glass then metal sinking into the flesh of our target as I come down from my high. My safety is clicked on and suddenly there's nothing else but the warmth of John's back as he sticks me in the waistband of his jeans and runs- keeping us safe just as he had our new flatma- no, as he had Sherlock.

Guys... I don't even know ;M; ... XD ... _
