Sweat and Sin at the Seaside Gym

The moment Lena stepped into the hotel's private fitness room overlooking the crashing waves, the air thickened with heat. Her tight sports bra hugged her full tits, nipples already poking against the fabric as she watched me, her personal trainer for the week. I was Alex, shirtless and glistening from my own warm-up, my cock twitching in my shorts at the sight of her toned ass and the hungry way her eyes dragged down my abs. The seaside hotel buzzed quietly outside, but in here it was just us, the salt air mixing with the scent of her coconut lotion and my clean sweat.

"God, Alex, I've been thinking about this session all morning," Lena said, her voice low and breathy as she dropped her towel. She stretched her arms overhead, arching her back so her breasts strained forward. "My husband booked this getaway to 'reignite our spark,' but all I can think about is how your hands felt spotting me yesterday."

I stepped closer, my pulse hammering. The ocean roared faintly through the open balcony doors, but my focus was on the damp spot already forming between her thighs in those tiny shorts. "Then let's make this session count, Lena. No half-assed reps today. Strip those shorts off. I want to see how wet that pussy gets when you work for it."

Her eyes widened, but she didn't hesitate. With a wicked grin, she hooked her thumbs in the waistband and peeled the fabric down her long legs, kicking them aside. Her shaved pussy glistened under the morning light, lips puffy and slick. "Like this? Fuck, I've been dripping since breakfast imagining your big cock stretching me."

I grabbed her hips and lifted her onto the weight bench, spreading her thighs wide. My fingers traced her slit, dipping inside her tight heat. She moaned loud, gripping my shoulders as I pumped two fingers deep, curling them against her g-spot. The wet sounds filled the room, louder than the waves outside.

"Oh shit, Alex... right there," she gasped, her hips bucking. "Don't stop. My clit is throbbing so bad."

I dropped to my knees, burying my face between her legs. My tongue flicked her swollen clit while I finger-fucked her harder, sucking her juices that tasted like pure lust mixed with salt air. Lena's hands tangled in my hair, pulling me closer as her thighs trembled.

"Yes! Lick my pussy... make me cum on your tongue," she begged, voice breaking. Her first orgasm hit fast, her walls clenching around my fingers as she squirted a little, soaking my chin and the bench. She cried out, body shaking, but I didn't let up.

Standing, I shoved my shorts down. My thick cock sprang free, veins pulsing, pre-cum beading at the tip. Lena's eyes locked on it, licking her lips. "That dick is huge. I need it inside me now."

I flipped her over the bench, ass up, and slammed into her soaked pussy in one thrust. The bench creaked under us as I pounded her deep, my balls slapping her clit with every stroke. Her juicy ass rippled each time I drove forward, her moans turning into desperate whimpers.

"Fuck me harder, trainer," she panted, pushing back to meet my thrusts. "Use this pussy like it's your workout. God, you're so deep... hitting spots my husband never reaches."

I gripped her ponytail, pulling her head back as I railed her faster, the wet smack of skin echoing. Sweat dripped down my chest onto her back. After a few minutes I pulled out, spun her around, and sat on the bench, guiding her to straddle me reverse cowgirl so we both faced the sea view.

She sank down on my cock again, her tight walls gripping every inch. "Mmm, I love feeling you fill me up." Lena rode me hard, her ass bouncing, tits jiggling as she braced her hands on my thighs. I reached around to rub her clit in fast circles, feeling her get even wetter.

Her second climax built quick. "I'm gonna cum again... don't stop rubbing my clit!" She slammed down, grinding her pussy against me as waves of pleasure crashed through her. Her inner muscles milked my shaft, squeezing so tight I groaned.

I couldn't hold back anymore. "Cum with me, Lena. Take every drop." I thrust up into her, burying myself to the hilt as my cock pulsed, flooding her spasming pussy with thick ropes of hot cum. She shook through another orgasm, her juices mixing with mine, dripping down my balls onto the floor.

We stayed locked together, panting, the ocean breeze cooling our sweaty skin. Lena turned her head, kissing me sloppily over her shoulder.

"Best workout I've ever had," she whispered with a satisfied laugh. "Same time tomorrow? My husband can play golf while you train this slutty pussy again."

I grinned, still buried inside her. "Count on it. This hotel gym just became my favorite place to fuck at work."
