Coach’s Claim

I never thought I’d get addicted to pain.

My name is Tyler. Twenty-four, decently built from years of inconsistent gym habits, but nothing compared to the guys who lived in the weight room. I’d joined this upscale gym six weeks ago on a whim, hoping to finally sculpt the body I always wanted. What I got instead was him — Coach Kane.

Kane was a fucking god. Thirty-two, 6’4”, packed with dense, veined muscle that looked carved from stone. Broad shoulders, thick chest, arms that strained every shirt sleeve, and legs like tree trunks. He ran the personal training program, and after my second week he’d cornered me after a session and offered a “specialized package.” Discounted rate. Late-night sessions when the gym was nearly empty.

I should have said no. But the way his eyes raked over my body, the deep timbre of his voice when he said “You’ve got potential, kid. Let me push you,” had me signing the paperwork that same day.

Tonight was our latest session. The gym closed at 10 PM. It was already 10:45 when we finished the final set of deadlifts. My legs were shaking, back on fire, sweat pouring down my face and soaking my tank top.

“Form was sloppy on the last reps,” Kane growled, standing way too close behind me. His massive chest brushed my back as he corrected my posture one last time. The heat rolling off him made my skin prickle. “You’re holding back. I told you — full commitment or you’re wasting both our time.”

“I’m trying, Coach,” I panted, gripping the bar.

He stepped even closer, his thick thigh pressing against my ass. “Not good enough. Shower up. Sauna in ten. I’m giving you a proper reward for the effort… and a corrective lesson for the sloppiness.”

My stomach flipped. The private sauna in the trainers’ section was off-limits to regular members. I’d heard rumors — intense recovery sessions, oil massages, that kind of thing. But the look in Kane’s eyes wasn’t professional. It was hungry.

I showered quickly in the empty locker room, heart hammering. My cock was already half-hard under the spray, betraying me. I told myself it was just the adrenaline from the workout. Nothing more.

When I entered the sauna wearing only a towel, Kane was already there. He sat on the top bench like he owned the place — towel barely covering his massive thighs, broad chest glistening with sweat, tattoos dark against his tanned skin. His eyes locked onto me the second I stepped in, the heat cranked high.

“Drop the towel,” he ordered, voice echoing off the wooden walls. “Full exposure. No hiding in my sauna.”

I hesitated, pulse roaring in my ears. The door was closed. The gym was empty. But this felt like crossing a line I couldn’t uncross.

Kane’s gaze hardened. “Now, Tyler. Or I cancel the rest of your package and you can go back to being another soft guy who quits after a month.”

The threat hit hard. I needed this — the discipline, the results, the way he looked at me. My hands shook as I unwrapped the towel and let it fall. My cock, already thickening, bobbed in the steamy air.

Kane’s smirk was dark and satisfied. “Better. Look at you. Lean, but you’ve got the foundation. Now get over here. On your stomach. I’m going to work those muscles properly.”

I climbed onto the bench, lying face down. The wood was hot against my skin. Kane poured oil into his huge palms — something that smelled sharp and masculine — and started on my shoulders. His hands were powerful, digging deep into knotted muscle, forcing groans out of me. He worked down my back, thumbs pressing along my spine, then lower… spreading my ass cheeks without shame.

“Coach—” I started, tensing.

“Quiet.” His voice was low, dangerous. One thick, oil-slick finger circled my hole before pushing inside without warning. I gasped sharply at the intrusion, the burn mixing with the intense heat of the sauna. “You’ve been staring at my body for weeks. Don’t act surprised when I finally take what’s been offered.”

He added a second finger, scissoring roughly, stretching me while his other hand kept massaging my ass. Sweat poured off both of us. The air was thick, suffocating. My cock was rock-hard, trapped beneath me against the bench, leaking steadily.

“You’re tight,” Kane murmured, voice rough with lust. “Been saving this hole for a real man, haven’t you?”

I whimpered into my arm as he worked me open, curling his fingers against my prostate until my hips bucked involuntarily. The pleasure was overwhelming, shameful, addictive.

Kane pulled his fingers out and poured more oil directly onto my ass and his cock. I felt the fat, heavy head press against my entrance — thick, hot, relentless.

“Take a deep breath,” he said. Then he pushed forward.

The stretch was brutal. I cried out as the head popped inside, followed by inch after thick inch of his massive cock. Kane groaned deeply, hands gripping my hips hard enough to bruise. “Fuck… that’s a good boy. Taking Coach’s cock so deep.”

He didn’t give me time to adjust. Once fully buried, balls pressed tight against me, he started thrusting — long, powerful strokes that slammed me into the bench. The sauna filled with the wet slap of oiled skin, my broken moans, and Kane’s low growls of satisfaction.

“Been wanting this since day one,” he confessed, pounding harder. “Gonna reward you properly tonight. Gonna ruin this hole and make you beg for more sessions.”

The heat, the oil, the raw dominance — it broke something in me. Pain melted into white-hot pleasure as he hammered my prostate relentlessly. I came first, untouched, shooting across the bench with a shattered cry. My hole clenched hard around him.

Kane roared and slammed deep, flooding me with thick, hot cum. He kept thrusting through it, grinding every drop inside.

But he wasn’t done. Not even close.

“Round two starts now,” he growled, already hardening again inside me. “Turn over. I want to see your face when I break you.”
