I never thought I'd end up here, on my knees in some stranger's apartment, staring at the thickest black cock I'd ever seen. It hung heavy between his legs, veined and dark, the head already glistening with precum. My own dick twitched in my pants even as my mind screamed this was wrong, but my mouth watered anyway.
His name was Marcus. We'd met at the gym a week ago, trading nods at first, then spotting each other on the bench. He was built like a tank, skin like polished ebony, and every time he grunted through a rep I felt something shift in my gut. Straight as an arrow my whole life, but that cock… fuck, it ruined me before I even touched it.
Tonight he invited me over for a beer after our workout. One beer turned into shots. We talked shit about women, sports, whatever. Then the conversation slid. He caught me staring at the outline in his shorts. "You curious, white boy?" he asked, voice low and rough. I tried to laugh it off but my face burned. He stood up, pulled his shorts down, and there it was. That massive black dick swinging free, already half-hard and bigger than anything I'd jerked to in secret.
"Suck it," he said, no bullshit. I hesitated, but my hand reached out on its own.

It felt hot and heavy in my palm, skin smooth over that rock-hard shaft. I leaned in and licked the head, tasting salt and musk. Marcus groaned, grabbed the back of my head, and pushed forward. The tip stretched my lips wide. I gagged as it hit the back of my throat, but he didn't ease up. "That's it, take that black cock. First time, huh? Your mouth feels fucking tight."
I bobbed my head, drool running down my chin, trying to breathe through my nose while he fucked my face in slow, deep strokes. My jaw ached but my own cock was leaking in my jeans. I reached down and squeezed it, moaning around his shaft. He pulled out after a few minutes, strings of spit connecting my lips to his glistening head. "Strip. Get on the bed. Ass up."
I obeyed like I was in a trance. Naked on all fours, I felt exposed as hell, my hole clenching at nothing. Marcus climbed behind me, spreading my cheeks with those big hands. He spat right on my hole, rubbed the head of his cock against it, and pushed. The burn was instant and brutal. I yelled into the mattress as that fat black cock forced its way inside, stretching me wider than I thought possible. Inch after inch sank in until his balls pressed against me.
"Fuck, you're tight," he growled, starting to thrust. Each push dragged against my prostate and sent sparks through my body. Pain mixed with this weird, dirty pleasure that made my dick throb and drip onto the sheets. He picked up speed, slapping my ass hard enough to leave handprints. "Take it, slut. First gay black cock and you're already moaning like a bitch in heat."
He reached around and stroked my dick in time with his pounding. The contrast of his rough grip and the relentless stretch in my ass pushed me over fast. I came hard, shooting ropes across the bed while he kept fucking through it. My hole spasmed around him, milking that thick shaft.
Marcus didn't stop. He flipped me onto my back, hooked my legs over his shoulders, and drove back in. The new angle let him go even deeper. I watched his dark cock disappear into my pale ass, the sight filthy and hypnotic. Sweat dripped off him onto my chest. He leaned down, kissed me rough, tongues fighting while he hammered away. "You love this black dick, don't you?" he muttered against my mouth. I nodded, too wrecked to lie. "Say it."
"I love your black cock," I gasped. "Fuck me harder."
He did. The bed slammed against the wall. His balls slapped my ass with every thrust. When he finally came, he buried himself to the hilt and unloaded deep inside me, hot pulses flooding my guts. I felt every spurt, my own spent dick twitching again at the sensation.
We lay there breathing heavy, his cock still inside me, softening slowly. He pulled out and I felt his cum leak out, running down my crack. Marcus smirked, wiped some on his fingers, and pushed it back into my hole. "Round two in ten minutes. That ass is mine now."
I didn't argue. My first gay black cock had already rewritten everything I thought I knew about myself.
