At the base of my skull, it pulses and lingers. It is not as sharp as usual, but it is more electric. I visualize it like a pool of lightening, swelling, throbbing, alive with desire but unwillingly confined. 

I draw a deep breath, wincing, when I am suddenly seized by the piercing sensation as it travels down my spine, like lightening dancing on my nerves. From my spine outward, it spreads, devouring me, leaving me breathless and drenched in passion.

At the base of my spine, it pulses and lingers, and I slowly drift to sleep.
