“A” stands for

Dave was enjoying it immensely. He lay panting, his eyes closed, seemingly riding the same train to climax town as I was. I stroked his thick cock, imagining the next time we’d meet, he would be fucking my ass with that gorgeous piece of meat. Delirium engulfed me, my movement became erratic, and seconds later my orgasm exploded, radiating in concentric circles from my groin out to every remote part of my body. As soon as my sperm started squirting out of my glans and filling his rectal passage, the heat and lubrication of our union soared, increasing my delight and compelling me to keep pumping in and out, until my hardness waned and my cum started spilling out of his hole.

I still had his boner in my pumping fist. I retreated and gobbled his cock in my mouth. I frantically started sucking him, desperately longing for him to fill my mouth once again. I didn’t have to wait long. Just in time I remembered the effect of the anal intrusion on his orgasm, because when I felt his muscles clench as an early warning of his climax, I plunged a finger deep in his cum dripping asshole and searched for that coarse bloated structure I had felt pulsing inside when he had cum earlier – his prostate – and stirred it just as his cock erupted and sprayed yet another delicious load of sperm in my hungry mouth. He buckled like a wild stallion, groaned loudly and grabbed my head, pushing me down roughly, until all of him was safely locked deep inside my throat. He kept pumping cum for a few more seconds, the warm and pulsing lump in his ass pushing against my finger. I pushed back, thinking that it would intensify and prolong his orgasm in some way. Judging by the time that passed before he finally let go of my head and sagged back onto the bunk, it seemed I was definitely on to something with that theory.
I tenderly finished him off, licking and kissing his cock and balls, cleaning up all the cum that had spilled, and licked his crack and asshole, drinking all of my own juices as well.
