I once had a dream in which I imagined a giant cock flying towards my mouth and there's nothing I can do about it. And I'm like "oh, man, I'm gonna have to suck this thing", and I brace myself to suck this giant cock. But then, at the last moment, it changes trajectory and hits me in the eye. I think "well, at least I got that out of the way", but then the giant cock rears back and stabs me in the eye again, and again and again.
Eventually this giant cock is penetrating my gray matter and I begin to lose control of my motor skills. That's when the giant cock slaps me across the cheek, causing me to fall off out of my chair. Unable to move and at my most vulnerable, the giant cock finally lodges itself in my anus, where it rests comfortably for 4, maybe 5 hours. That's what my dream was like.
