The gym locker room was bustling with activity, the air thick with the scent of sweat and the sound of clanging metal lockers. I had just finished a grueling workout, and all I wanted was a quick shower before heading home. My friend, Mark, was always a bit of a whirlwind, and today was no exception. He came barreling around the corner, his towel wrapped hastily around his waist, clearly in a hurry.

"Watch out!" he shouted, but it was too late. We collided with a force that sent both of us stumbling backward. His towel slipped from his grasp, and there it was—his dick, fully exposed. For a moment, time seemed to stand still as our eyes locked, and I couldn't help but stare. It wasn't just any dick; it was impressive, long and thick, with a slight curve that made it look almost mischievous.

Mark quickly recovered, snatching up his towel and wrapping it back around himself. His face flushed with embarrassment, but there was also something else in his eyes—curiosity, maybe even a hint of mischief.

"Well, that was awkward," he said, his voice tinged with a nervous laugh. "I guess you saw more than you bargained for."

I nodded, feeling my own face heat up. "Yeah, sorry about that. I didn't mean to—"

He cut me off, raising an eyebrow. "Hey, don't worry about it. But since you saw mine, I think it's only fair if I see yours."

My heart skipped a beat. Was he serious? The idea of stripping down in front of him, especially after what had just happened, was both thrilling and terrifying. But there was something about the way he said it, so matter-of-factly, that made it hard to refuse.

"Uh, okay," I stammered, my hands trembling as I reached for the hem of my shirt. I pulled it over my head, tossing it onto the bench beside me. Next came my shorts, and I hesitated for just a moment before pushing them down, revealing my boxers. I could feel Mark's eyes on me, intense and unwavering, as I stood there in nothing but my underwear.

"Take 'em off," he said, his voice low and commanding.

I swallowed hard, my mouth suddenly dry. Slowly, I slid my boxers down, letting them pool at my feet. My dick, already half-hard from the adrenaline rush, sprang free, bobbing slightly as I stood there naked in front of him.

Mark's gaze dropped to my erection, and I could see the appreciation in his eyes. "Nice," he murmured, stepping closer. "Mind if I touch it?"

The question hung in the air like a heavy fog, and I found myself nodding before I even realized what I was doing. Mark reached out, his fingers brushing against the tip of my cock, sending a shiver down my spine. He wrapped his hand around my shaft, his grip firm but gentle, and began to stroke me slowly.

"Fuck," I groaned, closing my eyes as the sensation overwhelmed me. His hand moved with practiced ease, sliding up and down my length, his thumb occasionally brushing against the sensitive underside. Each stroke felt electric, sending waves of pleasure coursing through my body.

"You like that?" he asked, his voice dripping with satisfaction.

I could only nod, unable to form words as he continued to work me over. His other hand snaked around to cup my balls, gently squeezing them as he stroked me faster. The combination of sensations was almost too much to bear, and I could feel my orgasm building, threatening to overwhelm me.

"Don't hold back," Mark whispered, his breath hot against my ear. "Let it go."

And with those words, I did. My hips bucked forward, and I came hard, my cum shooting out in thick ropes that landed on the floor between us. Mark kept stroking me until I was completely spent, his hand never faltering in its rhythm.

When I finally opened my eyes, Mark was smiling, his own dick now fully erect and pressing against the fabric of his towel. "Your turn," he said, his voice husky with desire.
