Climbing Gym First Submission

I stayed after the last of the intermediate group had packed up their chalk bags and drifted out into the parking lot, the gym lights humming lower the way they always did once the evening rush thinned. My fingers still smelled like magnesium and the cheap rubber of the holds. Twenty-eight years old and I still got that low flutter in my stomach every time Grant walked the mats during advanced technique—thirty-two, calm hands, that quiet way he corrected a foot placement without ever raising his voice. For weeks the banter had been thickening: him asking if I wanted the tighter figure-eight demo “just for fun,” me holding his gaze half a second too long while he coiled the dynamic line. We both knew. I just finally let myself ask.

“Grant?” My voice came out smaller than I meant in the empty main cave. He was racking biners near the auto-belays, black tee stretched across his shoulders, the faint rope burns on his forearms catching the light. “Could you… walk me through proper chest-harness tie-in? The advanced one. I keep second-guessing the knot when I’m pumped.”

He turned fully, one eyebrow lifting like he’d been waiting. The corner of his mouth moved—not quite a smile. “Now? Place is closed in twenty.”

“I know.” I stepped closer, climbing shoes still on, chalk dusting the insides of my thighs where my shorts rode up. “I want it right. From you.”

Something in his eyes darkened, warm and deliberate. He nodded once toward the training wall where the fixed ropes hung. “Shoes off. Stand here.”

I peeled them free, socks following, bare feet cool on the rubber mat. Grant pulled a hank of jute from his personal kit—not the gym’s smooth nylon, but rough, natural fiber that rasped when he shook it out. My pulse jumped. He stepped into my space until I smelled chalk and clean sweat and the faint cedar of whatever soap he used.

“Arms up.”

I lifted them. He started at my ribs, the rope sliding under my sports bra band, circling once, twice. Each pass was slow. He explained every move in that low instructor voice that had lived in my head during late-night fantasies.

“This is a basic Swiss seat variation into a chest harness. Bowline on a bight here—” his knuckles brushed the underside of my breast as he fed the bight through, “—so the load distributes across the ribcage, not the soft tissue. Feel that?”

I felt everything. The jute bit just enough, fibers catching on skin already damp. My breathing went shallow. He cinched the first knot against my sternum and the pressure bloomed outward, locking my chest in a firm embrace that made my nipples tighten hard against the thin fabric.

“Christ,” I whispered before I could stop it. “It’s… tight. The jute. I can feel every twist.”

Grant’s hands stilled for half a second. Then he continued, voice dropping another register as he worked the second wrap higher, framing my breasts, locking them in place so every inhale pressed me into the rope. “Good. You’re supposed to feel it. Tell me exactly.”

“It scrapes. In a way that makes me—” I swallowed, heat flooding low. “Aware. Of being held. Contained. I’ve thought about your hands doing this for weeks. Every time you demoed a figure-eight I imagined it around my wrists instead.”

He finished the final overhand, gave the whole structure a testing tug that rocked me forward onto my toes, and looked straight into my face. No teasing left. Just heat and absolute clarity.

“Simone.” My name in that tone made my knees soft. “Do you want to submit to me tonight? Here. Now. Rope, orders, the whole thing. I need the words. Clear yes or we coil this up and go home separate.”

The gym was silent except for the distant compressor and my own heartbeat in my ears. I didn’t hesitate. “Yes. I want to submit to you tonight. Completely. Please.”

“Consent noted.” A small, dark smile. “Safe word is ‘red.’ You say it, everything stops, no questions. Yellow if you need a breath. Understood?”

“Yes.”

“Good girl.” The praise landed like a hand between my legs. He stepped back half a pace, still holding the trailing end of the jute like a leash. “On your knees.”

I dropped. The mat was firm under my shins. The chest harness rode up with the motion, rubbing my nipples into tighter peaks, the rope creaking softly. Grant stood over me, one hand resting lightly on the top of my head, fingers sliding into my hair just enough to tip my face up.

“Look at you,” he murmured. “Finally where you belong. Hands behind your back. Palms out.”

I laced my fingers at the small of my back. The position arched me into the harness; every breath reminded me I was bound. He crouched so we were eye level, the free end of the rope trailing across my thigh like a promise.

“I’m going to finish dressing you in rope,” he said, voice calm, certain. “Wrists first, then maybe more if you stay this pretty and open for me. You’re going to tell me every time something feels too good or too sharp. No hiding. That’s the deal when you kneel for me.”

“Yes, Grant.” The words came out shaky with want.

He rose again, circled behind me. The jute whispered as he measured a new length. Cool air touched the small of my back where my shirt had ridden up. I could already feel the ghost of the next wraps—around my wrists, maybe up my arms, turning me into something presented and owned right here on the empty climbing mats. My cunt throbbed, slick against the seam of my shorts. I kept my eyes forward on the colored holds of the wall, breathing through the tight circle of rope across my chest, waiting for the next order, the next deliberate pull of fiber against skin.

He hadn’t even kissed me yet. Hadn’t touched me anywhere truly filthy. And I was already dripping, already aching to hear what he would demand next once my hands were useless and the harness locked me open for whatever lesson he decided I needed. The night was only beginning, the gym ours, and I knelt there burning, ready for every knot still to come.

He measured the next length of jute behind me, the fibers whispering against themselves, and I kept my palms turned out exactly as he’d ordered. The chest harness already owned every breath; each inhale scraped my nipples harder against the thin sports bra trapped beneath the coils. Grant’s knees brushed the mat as he crouched. Cool rope kissed the insides of my wrists.

“Cross them. Higher.”

I obeyed. He wound the jute in slow, deliberate figure-eights, pulling snug enough that my shoulders rolled back and the harness tightened another fraction across my tits. The burn of natural fiber on skin was immediate, perfect. He finished with a firm hitch that locked my hands useless at the small of my back, then tugged the trailing end like a lead.

“Up.”

I rose on shaky legs. The gym lights hummed. Crash mats waited in the open bouldering zone, thick blue foam still faintly chalk-dusted from the last session. Grant walked me there by the rope leash, my bound arms forcing my chest forward, every step rubbing the harness against swollen nipples. He stopped me at the edge of the largest mat.

“Bend.”

I folded at the waist. My cheek met the cool vinyl. Ass high, shorts stretched tight across it. He hooked fingers in the waistband and dragged both shorts and underwear down in one motion, leaving them tangled at mid-thigh so my legs stayed restricted. Cool air hit the slick mess between my thighs. I was dripping, cunt open and aching, the scent of my own want rising sharp under the chalk and rubber.

Grant’s palm smoothed over one cheek, then cracked down hard. The slap rang. Heat bloomed. I gasped into the mat.

“Count them when I give them. And keep those hips still until I tell you otherwise.”

“One,” I whispered after the second strike landed lower, right where ass met thigh. Three more followed, spaced, measured, each one jolting my bound chest against the foam. My cunt clenched emptily around nothing. Juice slicked the insides of my thighs.

He shoved two fingers into me without warning—thick, chalk-rough, curling. I moaned, fucking back onto them before I could stop myself. He let me for three strokes, then pulled free and wiped the wetness across my already-stinging ass.

“Greedy already. Good.” Fabric rustled. The heavy sound of his belt, zipper. The blunt head of his cock nudged my entrance, thick and hot, and he pushed in one long, ruthless glide until his hips slammed flush to my bound wrists. Full. Stretched. I cried out against the mat, the rope creaking as my arms jerked uselessly.

He set a hard rhythm immediately—deep, punishing thrusts that rocked me forward with every stroke. One hand fisted in my hair, wrenching my head back so the harness bit tighter across my tits; the other cracked against my ass in time with the fucking. Slap, thrust, slap. The wet sounds of his cock driving into me filled the empty gym. My nipples dragged against the rope and bra with every jolt. I was already close, the dual burn of rope and palm and the thick stretch of him short-circuiting every thought except yes and more and please.

“Grant—fuck—I’m—”

“Not yet.” He hauled me upright by the hair and the chest harness, still buried deep, then spun me and shoved me onto my back on the mat. Bound arms pinned beneath me for half a second before he yanked them up and over my head, trapping the wrists against the foam with one strong hand. The new position arched my back, thrusting my rope-framed tits up. He hooked my trapped shorts off one ankle so he could shove my thighs wide and drive back into me, deeper this way, the angle hitting that place that made stars burst behind my eyes.

His free hand closed lightly around my throat—not crushing, just present, thumb and fingers framing my pulse, controlling my breath the same way the rope controlled my chest. He fucked me in long, grinding strokes, hips rolling so the base of his cock dragged over my clit every time he bottomed out. I could feel every ridge, every throb. The jute bit into my wrists above my head. My tits jiggled inside their rope cage with every thrust.

“Please,” I begged, voice raw. “Please let me come. I’ve been so good—I need—Grant, please—”

He squeezed just enough that my next inhale whistled, eyes locked on mine, that calm instructor focus now dark with pure ownership. “Beg properly. Tell me who this cunt belongs to tonight.”

“You—it belongs to you. My cunt, my mouth, everything. Please, Sir, I’ve been aching for weeks, every class, every time you corrected my hips I wanted this, wanted you to tie me open and use me—please let me come on your cock—”

He slammed in harder, the hand on my throat flexing in time, and growled, “Come.”

The orgasm shattered through me like a dropped belay. My bound body seized, cunt clamping down in hard, rhythmic pulses that milked him while I sobbed and shook, thighs trembling violently around his hips. Spit wet the corner of my mouth. The rope harness felt like the only thing holding me together while pleasure wrecked me from the inside out. He fucked me through every wave, never easing, dragging it out until I was oversensitive and whimpering, still begging without words.

Only then did he pull free. He straddled my ribs in one smooth move, fist flying over his slick cock. Two strokes, three, and he came with a low groan, thick ropes of heat striping across my bound tits—over the jute, over the thin bra, painting my collarbones and the upper curves of my breasts. Come dripped warm between the rope coils. He milked the last drops onto my sternum knot like a signature.

For a long moment the only sounds were our breathing and the distant compressor. He stayed over me, cock softening against my sticky skin, one hand still loosely pinning my wrists. His thumb stroked the frantic pulse in my throat once, gentler now.

“Look at you,” he murmured. “Covered in me. Rope marks already rising. And still so fucking wet.” He dragged two fingers through the mess on my chest, then pushed them into my mouth. I sucked clean without being told, tasting us mixed with chalk and salt. His eyes darkened further.

He eased off, rolled me carefully onto my side so the pressure left my bound arms, and began untying just enough of the wrist hitch to let blood flow better—but he left the chest harness locked tight and the wrists loosely re-bound in front of me with a quick overhand. A leash of remaining jute still trailed from the sternum knot.

“We’re not finished.” His voice was low, certain, already rebuilding the charge. He stood, cock hanging heavy and half-hard again, and offered a hand to pull me up. My legs wobbled. Come cooled on my tits; my shorts still dangled from one ankle. The gym felt suddenly larger, full of unused corners and hanging ropes and locked office doors. “There’s a private training room in the back with a proper rack and a locking door. You’re going to walk there on the leash, bare-assed, marked, and dripping. And once we’re inside, Simone… I’m going to teach you what it really means to stay open for me all night.”

I met his gaze, pulse hammering, cunt already clenching again around the phantom stretch of him. The harness creaked when I nodded.

“Yes, Grant.”

He tugged the jute lead, turning me toward the shadowed hallway past the auto-belays, and I followed on bare feet, wrists bound, tits painted and framed in rope, every step a wet reminder that Act one had only been the warm-up. The real lesson was waiting behind that door, and I burned to learn every inch of it.

I followed the tug of the jute leash down the shadowed hallway, bare feet silent on the rubber, shorts still dangling from one ankle and come already cooling in sticky stripes across the rope that framed my tits. Every step made the chest harness creak and shift, fibers rasping my nipples into fresh peaks while fresh slick coated my inner thighs. Grant unlocked the private training room with a quiet snick of the deadbolt. The space was smaller, warmer, lit by a single overhead that threw hard shadows across the wall-mounted rack of training holds, the thick crash pad in the center, and a low bench bolted to the floor. He locked us in.

“On the pad. Knees. Present.”

I dropped, wrists still loosely bound in front of me, and arched so the harness displayed everything he had already marked. He walked a slow circle, collecting more jute from a duffel he kept back here. The new rope was darker, oil-slicked in places from previous use. He lifted my bound wrists, threaded fresh coils from elbows to palms in a tight box tie that forced my shoulders open, then ran a connecting line up to the sternum knot so any pull on the chest harness yanked my arms higher. The stretch burned deliciously across my lats.

“Still green?” he asked, two fingers under my chin.

“Green. So green it hurts.”

He smiled that dark instructor smile and stripped completely, cock already thick again, the head glistening. He sat on the bench, guided me forward by the leash until I straddled his thighs facing him, then shoved the head of his cock straight up into my cunt in one ruthless thrust. I sank down with a broken moan. The angle drove him impossibly deep; the ropes locked my torso upright so I could only bounce the way he allowed. His hands gripped the side coils of the harness and used them like handles, slamming me down onto every upward thrust.

“Ride it. Show me how badly you needed this after every class.”

I worked my hips, grinding clit against the base of him on every downstroke, the jute biting deeper with the movement. Sweat mixed with the earlier stripes of cum; the wet filth of it smeared between us. He leaned in and finally kissed me—slow, claiming, tongue fucking my mouth in the same rhythm his cock fucked my cunt. I came hard around him almost immediately, walls fluttering and milking, a broken sob against his lips. He didn’t stop. He stood with me still impaled, carried me two steps, and pressed my back to the cool wall beside the rack. One hand hooked a spare biner through the sternum knot and clipped it high to a bolt so I hung half-suspended, toes barely touching, legs forced wide around his waist while he pounded up into me.

The new tension stretched every rope mark into bright fire. My bound arms were useless above the clip. He fucked me like he was teaching a final exam—precise, relentless, watching my face for every flicker. When I started babbling again he pulled out, spun me, and bent me over the bench. Fresh rope cinched my thighs open to the wood. He mounted me from behind and drove home, one hand fisted in my hair, the other reaching under to pinch and roll my clit in time with the thrusts until I shattered a second time, gushing around him, crying his name into the vinyl.

Only then did he pull free, stroke himself twice, and paint me again—thick ropes across my already-marked ass, the small of my back, the rope harness, even a few hot splashes that reached my hair. He rubbed the last of it into the jute coils like he was sealing a claim.

I hung there afterward, still clipped, still bound, dripping and shaking and utterly wrecked in the best way. My voice came out raw and breathless when I finally found it.

“Thank you… Grant. That was the perfect first scene. Everything I needed. Everything I’ve wanted for weeks.”

He unclipped me carefully, caught my weight, and lowered me to the pad. The aftercare kit came out of the same duffel—soft towels, water, a small bottle of lotion that smelled clean and faintly of aloe. He worked the knots loose one by one, slow and deliberate, pausing to kiss each new rope mark as it appeared: the pink lattice across my ribs, the deeper grooves at my wrists, the hot stripes where the harness had framed my tits. Cool lotion followed his fingers, massaged in gentle circles until the sting eased into a glowing ache. He cleaned the mess between my legs with the same quiet focus he used correcting footwork, then wrapped a soft blanket around my shoulders and pulled me into his lap.

“You did so well,” he murmured against my temple. “Took every inch of rope, every order, every drop. This was only the beginning of your training as my submissive. Next session we go further—longer suspension, heavier impact, maybe the full body harness while you climb for me. You’ll wear my marks under your clothes at the gym and remember exactly who you belong to when you’re pumped out on the wall.”

I melted against his chest, glowing, already aching for the next time the lights dimmed and the mats emptied. My body hummed with the memory of every knot and every thrust; my mind floated in that soft, open place only true surrender creates. Anticipation curled warm and bright in my belly for whatever lesson waited behind the next locked door.

And the entire night had been exactly the scene I paid him to give me after I answered his discreet ad.
