I never expected my first time with a guy to go down like this. Straight my whole life, or so I told myself, until that night at the bar when Marcus caught my eye. Big, dark-skinned, built like he lifted cars for fun. We talked, drank, and when he said he had something massive waiting back at his place, I followed. Curiosity, horniness, whatever. I was 28, horny as fuck, and ready to cross that line.
His apartment was dark and quiet. The second the door shut, Marcus pushed me against the wall and kissed me hard, tongue deep. My dick jumped in my jeans. He grabbed my ass and growled, "You ever had black cock before?" I shook my head. "First time anything gay." He smirked. "Then you're gonna remember this monster."
We stripped fast. His body was all muscle and smooth dark skin. When he dropped his boxers, my mouth went dry. That cock was a fucking monster—thick, veiny, jet black, easily ten inches and heavy as hell, the head already glistening. "On your knees," he ordered.

I dropped and opened up. The taste hit me first, salty and strong. I choked trying to suck it, spit running down my chin while he held my head and fed me more. "That's it, white boy. Suck that big black dick."
My own cock throbbed untouched. Marcus pulled me up, bent me over the couch, and spread my cheeks. One thick finger pushed inside, then two, working lube deep. It burned but felt good. "Relax. This monster's going in raw." He pressed the fat head against my hole and pushed. I grunted loud as it stretched me open, inch after thick inch sliding into my virgin ass. It hurt like hell at first, then the pain mixed with something hot and electric.
He didn't go slow. Once he was balls-deep, he started pounding. That huge black cock slammed in and out, rearranging my guts with every thrust. "Fuck, you're tight," he grunted, gripping my hips hard. Skin slapped skin. My ass clenched around him, milking that monster. I reached down and jerked myself, moaning like a slut. "Harder. Fuck me harder."
Marcus flipped me onto my back on the floor, legs over his shoulders, and drove back in. The angle hit something inside that made my eyes roll. He fucked like a machine, sweat dripping off him onto my chest. "Gonna breed this ass," he said. "First gay load, right here." My hole spasmed at the words. I came first, shooting across my stomach without touching myself again. Marcus roared and buried deep, cock pulsing as he pumped what felt like a gallon of hot cum into me. It overflowed, leaking out around his shaft in thick white creampie strings.
He stayed inside, grinding slow while we caught our breath. When he finally pulled out, cum poured from my wrecked hole. I lay there shaking, ass gaping, already wanting more. Marcus grinned down at me. "Round two in ten. That monster ain't done with you yet."
