Firm Ass in the Empty Gym

The gym lights were already dimming when I spotted her. Lena bent over the cable machine, her black leggings stretched so tight across that firm, round ass it made my cock twitch instantly. We hadn't spoken in six months since the breakup, but the heat between us never died. The last trainer had just locked the front doors, leaving us alone in the echoing space that smelled of sweat and rubber mats.

"Hey, stranger," she said without turning around, her voice low and teasing. She knew I was staring. "You still working out this late, or just here to creep on your ex?"

I walked up behind her, close enough to smell her vanilla lotion mixed with the salty tang of her workout. "Couldn't stay away from that ass, Lena. Fuck, it's even tighter than I remember."

She straightened up slowly, turning to face me with that wicked little smirk. Her sports bra hugged her full tits, nipples already hard against the fabric. "Bold words for a guy who ghosted me after our last fight. You miss this?" She spun around again and popped her hips back, giving her ass a deliberate shake. The way those cheeks clenched made my mouth water.

"Miss it? I jerk off thinking about burying my face in it every damn night." I grabbed her waist, pulling her back against me so she could feel how hard I was. My hands slid down, cupping those perfect globes, squeezing hard. "Still so fucking firm. God, I want to spank it red."

Lena moaned softly, grinding back against my bulge. "Then do it, Mark. The place is empty. No one's coming back till morning." She reached behind her, palming my cock through my shorts. "I've been soaked since I saw you on the treadmill. This pussy needs your dick again."

We didn't waste time. I yanked her leggings down to her knees in one rough pull, revealing her bare, glistening pussy and that incredible ass completely. No panties. She never wore them when she trained. I dropped to my knees right there on the mat, spreading her cheeks wide.

"Look at this juicy fucking ass," I growled, burying my tongue between her cheeks. I licked from her dripping slit up to her tight little hole, tasting her tangy wetness and the clean sweat from her workout. Lena gasped, pushing back against my face.

"Oh shit, yes... eat my ass, baby. Fuck, your tongue feels so good on my hole." Her voice echoed in the quiet gym. I slapped one firm cheek hard, watching it jiggle before diving back in, sucking on her puckered anus while two fingers plunged into her soaked pussy. She was dripping down my wrist, clit swollen and begging.

Lena's legs shook. "I'm gonna cum already... don't stop licking my ass!" I fingered her faster, curling against that spot inside her while my tongue pushed into her tight ring. She exploded with a sharp cry, pussy clenching around my fingers, ass flexing against my mouth as fresh juices ran down her thighs.

Before she could catch her breath, I stood up, shoving my shorts down. My thick cock sprang free, veins pulsing, head already leaking precum. I bent her over the weight bench, that perfect firm ass up high.

"Spread it for me," I ordered. She reached back, pulling her cheeks apart so I could see everything. I rubbed my cockhead up and down her slit, teasing her clit before slamming in deep.

"Fuuuuck!" she screamed, the sound bouncing off the mirrors. "Your cock is so big... stretching my pussy so good." I gripped her hips and started pounding her hard, the wet slap of my balls against her clit filling the gym. Her ass rippled with every thrust, those tight muscles flexing around me as I drove in balls-deep.

I couldn't resist. I pulled out, slick with her cream, and pressed my cock against her asshole. "Want it here too? This firm little ass needs to be fucked."

"Yes," she panted, looking back at me with pure lust. "Put it in my ass, Mark. I want to feel you stretch me." I spat on her hole for extra lube and pushed in slowly, watching her tight ring swallow every inch. The heat was insane, her ass gripping me like a vice.

"Holy shit, you're so fucking tight back here," I groaned, starting to thrust. She pushed back to meet me, moaning like a whore. "Harder! Fuck my ass harder!" I reached around and rubbed her clit furiously while I railed her, the bench creaking under us. Her firm cheeks slapped against my pelvis, red handprints blooming where I'd spanked her.

We switched again, me sitting on the bench so she could ride me reverse cowgirl. Lena lowered her dripping pussy onto my cock first, then switched to her ass, sinking down until I was buried to the hilt in that perfect bubble butt. She bounced hard, tits jiggling in her bra, one hand between her legs rubbing her swollen clit.

"I'm cumming again... fuck, I'm cumming on your dick in my ass!" Her whole body shook, asshole pulsing around me in waves. The sight of her firm ass swallowing my cock pushed me over. I grabbed her hips and held her down, pumping rope after thick rope of hot cum deep inside her ass.

We stayed like that, panting, sweat dripping onto the floor. She leaned back against my chest, turning her head for a messy kiss.

"Still the best fuck I've ever had," she whispered, clenching her ass around my softening cock. "Maybe we should fight more often if this is the makeup sex."

I chuckled, squeezing one of those firm cheeks. "Or maybe we just skip the fighting and meet here after closing every week. This ass is worth it."

Lena smiled, standing up slowly so my cum could drip down her thighs. "Deal. Now help me clean this mat before the night janitor shows up."
