I was 28, married, and straight as they come until that night at the gym. I'd been lifting heavy after work, sweat dripping down my back, when this guy named Mark started spotting me on the bench. He was built like a truck, short beard, cocky grin. We chatted about reps and protein shakes. Nothing weird. Then he mentioned his place was nearby and he had a sauna. "Come over, relax those muscles," he said. I figured why not, just two dudes hanging out.
We got to his apartment and stripped down in the locker-room style bathroom. My cock was soft, hanging there, no big deal. But when he stepped out of his shorts, his dick was already half-hard, thick and veiny. I looked away fast, but my own cock twitched. What the fuck? I told myself it was nothing. We sat in the sauna, steam rising, talking sports. Then his hand brushed my thigh. "You ever think about trying something different?" he asked, voice low. I laughed it off, but my heart was pounding.
Next thing I knew, his hand was on my dick, stroking it slow and firm. It got hard instantly, betraying everything I thought I was. "Feels good, doesn't it?" he said. I nodded, mouth dry. He leaned in and kissed me, tongue pushing past my lips. It was rough, male, nothing like my wife's soft kisses. I kissed back, hating how much I liked it. He grabbed my hand and put it on his cock.
It was hot, pulsing, bigger than mine. I wrapped my fingers around it and started jerking him, feeling the skin slide over the shaft.
Mark pushed me back on the bench and went down on me. His mouth swallowed my cock all the way to the balls in one go. Hot, wet, tight. No woman had ever sucked me like that. He bobbed his head, tongue swirling the head, sucking hard on the upstroke. I groaned and thrust into his mouth, fucking his face without thinking. My straight brain was screaming, but my body was all in. Pre-cum leaked out of me and he licked it up.
I wanted to taste him. I pulled him up and shoved him against the wall. His cock slapped my cheek. I opened my mouth and took the head in. Salty, musky, different from anything. I gagged at first but kept going, sucking like I'd seen in porn. Mark held my head and fed me more, inch by inch until my nose hit his pubes. I choked but didn't stop. My own cock was dripping on the floor.
We moved to his bedroom. He bent me over the bed and spread my ass. His tongue hit my hole and I almost came right there. He licked and probed, getting me wet and open. Then a finger slid in, then two, stretching me. It burned but felt fucking amazing. "You want my cock in this tight straight ass?" he growled. I nodded, voice gone.
He slicked up with lube and pressed the head against my hole. It hurt at first, a sharp stretch, but he went slow, pushing in until his balls rested against me. Full. Owned. He started fucking me in long strokes, hitting something inside that made my cock leak onto the sheets. I pushed back, meeting every thrust. "Harder," I grunted. He pounded me, skin slapping, balls swinging. I reached down and jerked my own dick in time with his thrusts.
We switched positions. I rode him, sinking down on that thick cock over and over, ass clenching around it. Mark grabbed my hips and slammed up into me. Sweat poured off us. My orgasm built fast. I shot ropes of cum across his chest without even touching my cock. He followed right after, flooding my hole with hot load. I felt it pulse inside me, marking me.
We lay there breathing hard. I knew I'd crossed a line. My wife was at home. But my ass was sore and satisfied in a way nothing else had been. Mark pulled out and I felt his cum drip down my thigh. "Round two?" he asked. I was already getting hard again. That night I stopped being just a straight guy. I became the kind of man who craves cock, and I haven't looked back since.
