A little of both

My head slurped up and down Jimmy's raging hard-on, whil my hips kept time with my mouth, thrusting into Jimmy's face. I felt his lips withdraw, and I heard a hoarse voice that I would not have known was his cry out, "Oh, God, John, I'm about to cum! Gonna cum! Ungh!"

I felt his legs and hips begin to shudder as his orgasm began deep in his crotch. I sucked harder, squeezing my eyes shut as I clamped my mouth over his cock. I made lusty slurping noises over his meat, the imminence of his cum filling me with erotic abandon. And then Jimmy thrust his dick deep into my mouth, his back arching and a loud grunt escaping from his throat. "Unnnhh!"

I felt hot wet spunk splash into my throat, shooting from Jimmy's dick. I didn't swallow, but let it fill my mouth, keeping my lips wrapped tightly around his shaft. He thrust once, twice, then three times, each time spurting another helping of his jism into my face. As he began to relax, I loosened my grip on his prick and allowed the cum to drop out of my mouth, down his cock and over my hand as I stroked him. Watching his spoo flow from between my lips and over my knuckles made me feel incredibly nasty, which only turned me on even more.
