The second I walked into his apartment I knew what was happening. No small talk, no bullshit. Mark slammed the door and shoved me against it, his hand already grabbing my cock through my jeans. "You want this ass fucked raw tonight?" he growled. I nodded and said, "Fuck yeah, bend over."
He stripped fast, dropping his shorts and bending over the kitchen counter, spreading his cheeks with both hands. His hole was already slick from lube he'd worked in earlier. I dropped my pants, spit on my cock, and lined up. No slow tease. I pushed the head in and sank balls deep in one hard thrust. Mark grunted loud. "Shit, that's it, pound my fucking hole."
I grabbed his hips and started slamming into him. Every stroke went all the way out and back in deep. His ass cheeks slapped against my thighs. Sweat already coated his back. I reached around and jerked his cock while I fucked him, keeping the pace rough and steady. He pushed back to meet every thrust, moaning, "Harder, fuck me like you mean it."
We moved to the couch. He got on all fours and I mounted him again, driving in even deeper from behind. The angle let me hit his prostate on every stroke. His hole clenched tight around my shaft. I spat on his back and rubbed it in while I kept pounding. "Your ass is so fucking tight," I told him. He answered by reaching back and spreading himself wider for me.
I flipped him onto his back, hooked his legs over my shoulders, and folded him in half. My cock never left his ass. I fucked straight down into him, watching his face twist with every thrust. He stroked himself fast, eyes locked on mine. "Don't stop, fill me up," he begged. I went faster, hips snapping, balls slapping against his ass. The wet sound of my cock pounding his lubed hole filled the room.

When I got close I pulled out, flipped him onto his stomach again, and shoved back in. I fucked him prone, my full weight on top of him, grinding deep. He came first, shooting across the couch cushion while his ass squeezed my cock. That pushed me over. I buried myself to the root and unloaded, pumping hot cum straight into his guts. I kept thrusting through it, pushing every drop inside him.
We stayed locked together, breathing hard. I stayed inside until I softened, then pulled out slow so he could feel the load leak. Mark turned his head and grinned. "Round two in ten minutes. This time I want you on your back so I can ride that cock."
I nodded, already getting hard again at the thought of his cum-filled ass bouncing on me.
