Firm Ass Reunion

The moment I spotted her bent over the weight bench, sweat glistening down the curve of her back, my cock twitched hard. Lena. My old high-school classmate, the quiet girl who used to sit two rows behind me. Ten years later and that ass—Jesus, that firm, round ass—was even better than the fantasies I used to jerk off to. The gym was almost empty, lights dimming for closing in twenty minutes, and the air smelled of rubber mats and her faint vanilla lotion.

"Lena?" I said, walking closer, voice low.

She straightened, ponytail swinging, and turned. Her tight black leggings hugged every inch of those powerful thighs and that perfect peach of an ass. Her sports bra barely contained her full tits. Recognition flashed in her green eyes, followed by a slow, dirty smile.

"Mark? Holy shit. You still look like you could bench a truck." She wiped her forehead with the back of her hand. "Didn't expect to run into you here right before they kick us out."

"Yeah, I switched gyms last month. You... damn, you changed." My gaze dropped again. I couldn't help it.

She caught me staring and laughed softly, that husky sound going straight to my dick. "You mean my ass got better, right? I work it hard now. Squats, deadlifts, the works." She turned sideways, giving me the full view, and flexed. The fabric stretched tight over those firm cheeks. "Like what you see, old classmate?"

"Fuck yes," I admitted, stepping closer. The tension crackled between us like live wire. "Been staring at it since I walked in. That ass is criminal, Lena."

Her cheeks flushed but her eyes darkened with heat. She glanced toward the front desk—empty, the last trainer already gone—then back at me. "Closing soon. You wanna... help me stretch it out?"

We didn't even make it to the locker room. She grabbed my hand and pulled me behind the row of treadmills, into the dimly lit corner near the stretching mats. My hands were on that firm ass instantly, squeezing the tight muscle through her leggings. She moaned, pushing back against my palms.

"God, Mark, you've got big hands," she whispered, grinding her ass against the growing bulge in my shorts. "Feel how tight it is? I want your cock right here."

I yanked her leggings down just enough, exposing that smooth, sweat-slicked ass. No panties. Her shaved pussy lips were already glistening. I dropped to my knees, spread those firm cheeks, and dragged my tongue straight up her slit.

"Oh fuck!" she gasped, gripping the wall. "Lick my pussy like that... yeah, just like that."

I devoured her, tongue flicking her swollen clit then circling her tight little asshole. She tasted salty-sweet, her firm ass flexing under my grip as she rocked back onto my face. Her moans echoed softly in the empty gym.

"Mark, I'm gonna cum if you keep eating my ass like that—shit!"

I stood up, shoved my shorts down, and freed my thick cock. It slapped against her firm cheek with a wet sound. "You want this dick?"

"Yes. Fuck me. Right now." She reached back, spreading her ass wider. "Put it in my pussy first. I need to feel you stretch me."

I rubbed the fat head along her dripping folds, then thrust in hard. Her walls clamped down, hot and silky. "Jesus, you're tight," I growled, gripping her hips and pounding deep. The sound of my hips smacking that firm ass filled the corner—wet, rhythmic slaps.

Lena pushed back, meeting every thrust. "Harder. Fuck my pussy harder. I've wanted this since senior year, you idiot."

I reached around and rubbed her clit in tight circles while I railed her. She came fast, shuddering, her cunt pulsing around my cock, juices running down her thighs. "Oh god, I'm cumming—fuck!"

Before she could catch her breath I pulled out, spun her around, and sat on the bench, dragging her onto my lap facing away. Her leggings were tangled at her knees. I guided my slick cock back into her dripping pussy, then grabbed two handfuls of that incredible firm ass and bounced her on me.

"Look at this perfect ass bouncing on my dick," I groaned, spanking one cheek lightly. It jiggled just enough, then tightened again. "So fucking hot."

She rode me reverse cowgirl, hands braced on my knees, that round ass rippling with every drop. "Spank it again. I love it rough." I obliged, smacking the other cheek, watching the skin pink up. Her moans grew louder, breathy.

I felt my balls tightening. "I'm close, Lena. Where do you want it?"

"In my ass," she panted, lifting off my cock. She reached back, spreading her cheeks, showing me that puckered hole. "I've been training it. Put your cock in my ass and fill me up."

The head of my dick pressed against her tight ring. She pushed back slowly, taking me in inch by inch, gasping and swearing. "Fuck, it's so big... stretch my ass, Mark. Deeper."

Once I was buried balls-deep in that firm, clenching heat, I started thrusting. She rubbed her clit furiously, her pussy dripping onto my thigh. The gym lights flickered once—last warning before total shutdown—but we didn't stop.

"Harder. Pound my ass," she begged, voice breaking.

I gripped her ponytail and fucked her harder, the bench creaking under us. Her firm ass took every brutal inch, cheeks rippling, hole gripping me like a vice. She came again, squirting a little, crying out my name.

That pushed me over. I buried myself deep and unloaded, thick ropes of cum flooding her ass. "Take it all, fuck—"

We stayed locked together, panting, sweat dripping. She turned her head, kissed me sloppily over her shoulder.

"Same time next week?" she whispered, clenching her ass around my softening cock with a wicked grin.

"Wouldn't miss watching this firm ass for the world."
