Chapter 3:

Tension Builds

I was still catching my breath from the warm ups when Dom clapped his big hands together, the sound echoing off the mirrored walls. My legs felt a little shaky already, and we’d only been going for twenty minutes. He loomed over me, sweat starting to glisten on his tattooed chest, those gray sweatpants hanging low on his hips. God, the man was built like a wall.

“Alright, Riley, time to ramp it up,” he said, voice that deep rumble that always hit me right in the gut. “Squats. Real ones. Not that light shit you do at college. Grab the barbell. We’re doing sets of eight, deep as you can go. I want to see your ass nearly touch the floor.”

I nodded, wiping my forehead. “Okay, Coach. I’ll try.”

“Trying ain’t enough,” he shot back, stepping behind me as I positioned myself under the bar. His hands came down on my shoulders first, adjusting my stance. “Feet wider. Shoulder width plus two inches. There. Now drop. Slow on the way down. Control it.”

I bent my knees and lowered, feeling the burn hit my thighs immediately. The tiny black shorts rode up even higher, digging into me. On the third rep, Dom moved closer, his body heat blasting against my back.

“Deeper, kid. All the way,” he growled, one hand pressing firmly on my lower back while the other gripped my hip. “Push that ass back. Like you’re sitting on something. Yeah… just like that. Hold it at the bottom for two seconds.”

I held, thighs trembling. “Coach, it’s burning already. My legs feel like jelly.”

“Good. That’s the point. You wanted me to push you, remember?” His fingers dug in a little harder on my hip, pulling me down even further. “Four more. Don’t you dare half-ass these. I can see your form slipping. Arch your back more there. Fuck, look at you. So flexible but still so tight in all the right places.”

My face flushed hot. The way he said it… it didn’t sound like regular coaching. I finished the set and stood up straight, panting. Sweat was trickling down my spine, soaking into my tank top. Between my legs, I could feel myself getting seriously wet. The fabric of my shorts was starting to cling in a way that made me want to die of embarrassment.

Dom didn’t give me much rest. “Again. This time I’m spotting you closer. And stretches after. We’re gonna work those splits hard today.”

We did another set. This time he was right up against me, his crotch brushing my ass every time I dropped low. I could feel the heavy outline of him through his sweatpants. It made my pussy throb so bad I had to bite my lip to stay quiet.

“Coach… you’re really close,” I whispered during the hold at the bottom.

“Damn right I am,” he replied, voice low and commanding right by my ear. “How else am I supposed to fix that lazy posture? Keep your core tight. Squeeze those glutes at the top. Good girl. Fuck, you’re getting stronger. But something else is getting wetter, isn’t it?”

I nearly lost my balance on the next rep. “What? No, I….”

“Don’t lie to me, Riley.” His hand slid from my hip to my lower back again, but this time it lingered, pressing just above my ass. “I can see the spot forming on those tiny shorts. Right between your legs. You’re soaking through, kid. Every time I push you down, you drip more. That turn you on? Your old Coach manhandling you like this?”

My heart hammered. I finished the set on shaky legs and turned to face him, crossing my arms over my chest like that would hide anything. “It’s just sweat, Coach. It’s hot in here. You’re making me work really hard.”

Dom stepped forward, towering over me. He tilted my chin up with one thick finger, forcing me to look into his eyes. “Sweat doesn’t leave dark wet patches right on your pussy like that. I’ve been training girls for years. I know the difference. You’re fucking drenched. And it’s not the first time I’ve noticed either.”

I swallowed hard, thighs pressing together instinctively. The pressure only made it worse I could feel more slickness leaking out. “I… okay, maybe a little. But it’s embarrassing. You’re forty-five, I’m nineteen. You’re my trainer. This shouldn’t be happening.”

“Shouldn’t?” He smirked, that possessive glint in his eyes making my knees weak. “Your body doesn’t seem to agree. Look down. Those shorts are ruined. Turn around and show me in the mirror.”

I hesitated, but his stare didn’t leave room for arguing. I turned, and there it was clear as day in the reflection. A obvious damp spot right at my crotch, the black fabric darker and clinging to my folds.

“See that?” Dom said, standing behind me now, his hands on my waist. He pulled me back against him so I could feel his cock, half-hard and massive, pressing against my ass. “That’s not sweat, little athlete. That’s your tight college pussy reacting to a real man correcting your form. You like when I get aggressive, don’t you? When I spread you wide and push you deeper.”

“Yes…” I admitted in a small voice, barely above a whisper. “It feels good when you touch me like that. I get all tingly and… wet. I can’t help it.”

“Damn right you can’t.” His voice dropped even lower, rougher. One hand slid down my stomach, stopping just above the waistband of my shorts. “We’re not even at the real stretching yet. You think this is bad? Wait till I have you oiled up and legs pinned back. But first, more work. Straddle stretch on the mat. Now.”

I moved to the mat and sat down, spreading my legs wide into a straddle. Dom dropped down right in front of me this time, his massive frame between my thighs. He grabbed my ankles and yanked me wider, almost painfully so.

“Deeper, Riley. Lean forward. Chest to the mat if you can.” His hands pressed on my inner thighs, thumbs digging into the soft skin. “Fuck, you’re flexible. But I bet I can make it better. How’s that feel?”

“It burns… but good,” I gasped, forehead nearly touching the mat. Sweat dripped off my face. My shorts were pulled so tight now that the seam rubbed right against my clit. “Coach, I’m getting even wetter. I can feel it dripping.”

“I know you can,” he growled, leaning in closer. His breath fanned over my neck. “I can smell it. Sweet and needy. You’re making a mess on my mats already. Keep holding. Tell me how bad you want me to stretch you deeper.”

“So bad,” I moaned softly, unable to stop myself. “I need it, Coach. Your hands… they make everything feel more intense. Please don’t stop pushing me.”

Dom’s grip tightened, spreading me another inch. “Good girl. That’s what I like to hear. But we’re just building tension here. Imagine what happens when I really start breaking you in. You think you’re wet now? Just wait.”

He released one leg and trailed his fingers slowly up my thigh, stopping inches from where I was aching most. I whimpered, hips twitching without meaning to.

“Coach… you’re teasing me.”

“Teasing?” He laughed darkly. “This is still training, kid. But yeah… I see how bad you need more. Keep stretching. We’ve got all day to see just how far you’ll let me take this.”

My whole body was on fire thighs burning, pussy throbbing, mind spinning. The age gap, the power he had over me, the way he talked… it was all too much. And we weren’t even halfway through the session yet.

Chapter 4:

The “Special Stretch” Offer

My body was already a sweaty, trembling mess after another round of squats and lunges. I stood there panting, hands on my knees, trying to catch my breath while Dom circled me like a predator. The mirrors showed everything my flushed cheeks, the dark wet patch between my legs that had only gotten worse, and him towering behind me, muscles gleaming with sweat.

“Fifteen more seconds on that plank, Riley,” he commanded, voice deep and rough. “Core tight. Don’t you sag on me now.”

I dropped back down, forearms burning as I held the position. “Coach… it’s so hard. My arms are shaking.”

“That’s because you’re weak in the middle,” he said, crouching beside me. His big hand pressed down between my shoulder blades, forcing me lower. “Engage everything. Ass down, back flat. Fuck, look at you holding it. Good little athlete. But I can see you dripping again. Those shorts are fucking ruined.”

I whimpered, hips twitching despite myself. “It’s not my fault. Every time you touch me or tell me to go deeper… I can’t control it.”

Dom chuckled darkly, his hand sliding down to my lower back, then dangerously close to my ass. “I know you can’t. That’s what I like about you, kid. Nineteen years old and your pussy soaks for an old man like me. Up. We’re switching to hip openers. On your back.”

I rolled over onto the mat, legs spread wide as he instructed. Dom grabbed my right ankle and pushed my knee toward my chest, then across my body in a deep twist. The stretch hit hard in my hip and groin.

“Talk to me,” he demanded. “How deep does that feel?”

“So deep,” I gasped, gripping the mat. “It burns right in my inner thigh. But… good burn.”

“Yeah? And what about here?” His free hand pressed firmly on my inner thigh, inches from my soaked crotch. “You’re throbbing, aren’t you? I can see your pussy pulsing through the fabric. Answer me honestly, Riley.”

My face burned hotter than the workout. “Yes… I’m throbbing. It’s embarrassing how wet I am. I’ve never been like this during training before.”

“Before me, you mean,” he corrected, switching to the other leg and stretching me even wider. “You’ve been coming to me for months and every session ends the same way. You leave here with soaked shorts and hard nipples. Today we’re not pretending anymore. How bad do you want me to really stretch you?”

I bit my lip, staring up at the ceiling as he held the position. “I do want it. But I’m scared. You’re my coach. You’re forty-five… I’m just nineteen. What if this gets out of hand?”

Dom released my leg and sat back on his heels, looking down at me with those intense eyes. “It’s already out of hand, kid. Look at the mess you made on my mat. Your college coaches don’t push you like this, do they? They don’t make you drip just from form corrections.”

“No,” I admitted softly, sitting up slowly. Sweat dripped down my neck and between my small tits. “They don’t. Only you do that to me.”

He stood up and offered me a hand, pulling me to my feet effortlessly. “We’ve been at this for over an hour now. Normal training’s done its job. You’re warmed up, soaked, and shaking. Time for the special stretch session I mentioned before.”

I wiped my forehead, heart racing. “Special stretch? What do you mean exactly?”

Dom stepped closer, his massive frame blocking out the light. One hand cupped my chin again, thumb stroking my jaw. “The kind that actually works, Riley. Deep flexibility work. But it requires oil so I can really get in there without friction. And less clothing. Actually… no clothing. I need full access to stretch you properly legs pinned back, hips open, everything exposed. You game?”

My stomach flipped. “Completely naked? Here? Coach, I… I don’t know. That’s really exposing.”

“Exactly,” he growled, voice dropping lower. “That’s the point. You want deeper splits? You want me to push your body past its limits? Then you strip. I oil you up real good, spread those pretty legs as wide as they’ll go, and work you until you’re screaming. No more hiding that dripping little pussy. I’ll stretch you so deep you’ll feel it for days.”

I shifted on my feet, thighs slick with more than just sweat now. The idea made me clench hard. “You promise it’s just stretching? I mean… you won’t… do anything else?”

Dom smirked, leaning down so his lips were close to my ear. “I promise I’ll stretch you deeper than you’ve ever been stretched. But if your body reacts? If that tight college cunt starts begging while I’ve got you folded and oiled? I’m not gonna ignore it. You’ve been teasing me with these tiny shorts for weeks. Time to be honest about what you need.”

I hesitated, chewing my lip. My pussy was aching so bad it hurt. “I’ve never done anything like this. What if I can’t handle it?”

“You can,” he said firmly, his hand sliding down to squeeze my waist. “You’re flexible as hell. And I’ll be right there, controlling everything. You trust your Coach, don’t you?”

“Yes,” I whispered, nodding slowly. “I do trust you. Okay… I’ll do it. The special stretch. Just… be careful at first?”

Dom’s eyes lit up with something dark and hungry. “Good girl. Lock the door behind you. Then strip. Everything off. I’ll get the oil warmed up. And Riley?”

“Yeah?”

“Once those clothes come off, there’s no going back to regular training today. You’re mine to stretch however I see fit. Say it.”

“I’m yours to stretch,” I repeated, voice shaky with nerves and excitement. My hands were already moving to the hem of my tank top.

He nodded approvingly. “That’s my little athlete. Now hurry up. I want to see every inch of that tight nineteen-year-old body glistening before I pin you open.”

I walked over and locked the gym door with trembling fingers, pulse pounding in my ears. This was crossing every line. But as I turned back and saw Dom grabbing a bottle of oil, his muscles flexing, that massive bulge obvious in his sweatpants, I knew I couldn’t stop now.

I pulled my tank top over my head, small tits bouncing free, nipples stiff. Then I hooked my thumbs into my soaked shorts and pushed them down, stepping out completely naked.

Dom’s gaze raked over me slowly. “Fuck, Riley. Even better than I imagined. Now get on the bench. Legs up. Let’s see how deep we can really go.”

My body was on fire, already throbbing in anticipation. The normal training was officially over.

Chapter 5:

Oiled and Exposed

I stood there completely naked, heart slamming against my ribs, as Dom walked over and double checked the lock on the gym door with a heavy click. The sound made everything feel so final. No turning back. My small tits were already heaving with each breath, nipples tight and sensitive from the cool air. I felt tiny next to him this massive, tattooed 45-year-old beast staring at my 19-year-old body like he owned it.

“On the workout bench, Riley,” he ordered, voice low and gravelly. “Lie back. Ass right at the edge. Legs up and spread for me.”

I climbed onto the padded bench, the leather cool against my bare skin. “Like this, Coach? God, I feel so exposed. Are you sure about this?”

Dom grabbed a bottle of oil from the shelf, warming it between his big palms. “Dead sure. Look at you tiny gymnast body all flushed and dripping already. You’re soaked down your thighs, kid. No more hiding that pretty pussy from your Coach.”

He poured the warm oil right over my chest first. It trickled down between my tits and over my stomach in slow, shiny streams. His hands followed, big and rough, spreading it everywhere.

“Fuck, your skin feels perfect,” he growled, massaging my small tits firmly, thumbs flicking over my nipples until I arched off the bench. “These little tits are so sensitive. You like when I play with them?”

“Yes… Coach, that feels really good,” I moaned, biting my lip. “But it’s embarrassing. No one’s ever touched me like this before.”

He laughed deep in his throat, hands sliding lower, oiling my abs and hips. “Good. Means this tight little body is mine to break in. Spread your legs wider. Yeah, just like that.”

The oil hit lower now, dripping right onto my pussy. I gasped as the warm liquid coated my folds. Dom’s thick fingers glided down, rubbing it in slow circles around my clit, then parting my lips.

“Oh my god,” I whimpered, hips twitching. “Your fingers are so big. Coach, please… I’m already so wet.”

“Damn right you are,” he said, voice rough with hunger. “This college pussy is dripping for an old man twice your age. Tell me how bad you need it stretched.”

“I need it so bad,” I admitted, voice shaky. “I’ve been aching since warm-ups. Please stretch me deeper, Coach.”

Dom gripped my ankles and pushed my legs back and out into a full split position, pinning them down on either side of the bench. I was completely open, pussy exposed and glistening with oil and my own slick. He leaned over me, muscles flexing, sweat already beading on his chest.

“Good little athlete,” he growled, staring right between my legs. “Look at this pretty pink cunt. So tight and ready.”

Two of his thick fingers pressed against my entrance, teasing for a second before sinking in deep. I cried out, back arching hard.

“Fuck! Coach, you’re stretching me already,” I gasped. “It’s so much… your fingers are filling me up.”

He started pumping them roughly, curling them inside me while his thumb found my clit and circled it fast. The wet sounds filled the gym obscene and loud. Oil and my juices mixed together, making everything slippery.

“That’s it, moan for me,” Dom commanded. “Let your Coach hear how much you love getting finger-fucked on his bench. This pussy belongs to me now, Riley. Say it.”

“It belongs to you,” I moaned loudly, legs trembling in the split hold. “My pussy is yours, Coach. Oh shit, I’m gonna….”

He didn’t slow down. His fingers thrust harder, faster, thumb pressing perfect circles on my swollen clit. The pressure built so fast I couldn’t hold it.

“I’m cumming!” I screamed, body shaking violently. A huge gush of wetness sprayed out around his fingers, soaking his hand and the bench. I squirted for the first time in my life, eyes rolling back.

“Fuck yes, good girl! Squirt all over your Coach’s hand,” he growled, not stopping. He kept fingering me through it, drawing it out until I was a shaking, whimpering mess. “First time squirting, huh? That’s what happens when a real man works this tight hole.”

I could barely breathe, aftershocks still hitting me. “Coach… I’ve never done that before. It felt insane. Please, I’m so sensitive now.”

But he wasn’t done. He added a third thick finger, stretching me even wider. The burn mixed with pleasure as he worked them deep, scissoring and pumping.

“Take it,” he snarled, leaning closer so his sweaty chest hovered over me. “This tight nineteen-year-old college pussy is getting stretched properly now. Feel that? Three fingers buried in you. You’re clenching so hard around me, kid. Greedy little thing.”

“It’s so deep,” I whined, tears pricking my eyes from the intense stretch. “You’re ruining me for anyone else. My pussy feels so full… but I love it. Don’t stop stretching me, Coach.”

Dom’s eyes darkened with pure possession. “That’s right. No one else gets this cunt anymore. It’s mine to finger, mine to fuck, and soon mine to breed full. You hear me, Riley? This is my pussy now.”

“Yes, yours,” I panted, hips trying to rock against his hand despite being pinned. “I’m your good little athlete. Stretch me more… please.”

He curled his three fingers just right, hitting a spot that made stars explode behind my eyes. Another orgasm crashed over me, smaller this time but still powerful, my walls pulsing around his thick digits.

“Such a good girl cumming again so quick,” he praised, voice rough. “Look at the mess you made. Bench is soaked. Your thighs are shining with oil and cum. We’re just getting started with these special stretches.”

I lay there trembling in the full split, legs pinned back by his strong hands, completely at his mercy. My mind was fuzzy with pleasure, but one thing was crystal clear I was addicted already. This 45-year-old beast had me naked, oiled, and stretched wide open after just one intense session.

And from the hungry look in his eyes, he wasn’t planning to stop anytime soon.
