Mark stood under the hot spray, letting the water wash away the sweat from his workout.
It was 11 PM. late enough that the gym was mostly empty, which was exactly why Mark preferred coming at this hour. He was still new to working out, still self-conscious about his smaller frame compared to the muscle-bound guys who dominated the weight room during peak hours.
The locker room was quiet. Empty, as far as Mark could tell. He'd been alone when he'd stripped down and headed to the showers, grateful for the privacy.
He closed his eyes, tilting his head back under the water, and that's when he heard it.
Footsteps.
Mark's eyes snapped open, and his breath caught.
A man stood at the entrance to the shower area....and "man" felt inadequate to describe him. He was massive. Six-foot-six at least, with muscles that looked carved from stone. Broad shoulders, thick arms covered in tattoos, abs that cast shadows in the fluorescent lighting, and thighs like tree trunks.
And he was completely naked.
Mark's eyes traveled down involuntarily and then froze.
Between the man's legs hung the biggest cock Mark had ever seen....soft, and it still had to be nine or ten inches. Thick as Mark's wrist. Dark, with prominent veins running along the shaft.
It looked less like a human appendage and more like some kind of... rod. A monster's rod.
"Mind if I join you?" the man asked, his voice deep and rough.
Mark realized he'd been staring. His face burned as he jerked his gaze back up. "Uh, no. I mean, yes. I mean.....there are other showers..."
"I like this one." The man moved closer, stepping under the spray head next to Mark's. Water cascaded over his impressive body, and Mark couldn't help but watch the way it ran down those muscles, following the grooves and planes.
"I'm Derek," the man said, extending a hand.
"Mark," he managed, shaking it. Derek's hand completely engulfed his.
"You're new here," Derek observed. "I've seen you around the past couple weeks. Always coming late, always leaving quick."
"I'm still getting used to it," Mark admitted.
"Nothing to be self-conscious about." Derek's eyes traveled over Mark's body slowly, deliberately. "You've got a nice build. Lean. Tight."
The way he said "tight" made Mark's pulse quicken.
"Thanks," Mark said, suddenly very aware that he was naked, wet, and alone with this massive man who was looking at him like.....
Derek stepped closer. Much closer.
"I've been wanting to talk to you," Derek said quietly. "But you always leave before I get the chance."
"Talk about what?"
"About this."
Derek's hand came up, fingers brushing along Mark's jaw, tilting his face up. And then Derek was kissing him....deep, demanding, claiming Mark's mouth like he had every right to it.
Mark should have pulled away. Should have protested. Should have done anything except what he did...which was melt into the kiss, his lips parting, letting Derek's tongue invade his mouth.
When Derek finally pulled back, Mark was breathless.
"I....we can't....someone could come in...."
"No one's here. Building closes in thirty minutes. It's just us." Derek's hand slid down Mark's chest, over his stomach, wrapping around Mark's hardening cock. "And from the feel of this, you want it as much as I do."
"I've never....not like this....not with someone...."
"Someone like me?" Derek's smile was knowing. "Someone big? Someone who could break you in half?"
Mark nodded, unable to form words.
"Good. Because that's exactly what I'm going to do." Derek's hand left Mark's cock and moved lower, between his legs, fingers pressing against his hole. "I'm going to fuck you right here. In this shower. And you're going to take every inch of my cock. Understood?"
"It won't fit," Mark whispered, his eyes dropping to that massive shaft—which was now hardening, growing, rising until it stood at full mast.
Fifteen inches. Maybe more. Impossibly thick. Absolutely terrifying.
"It'll fit," Derek said with absolute confidence. "Turn around. Hands on the wall."
