Firm Ass After Hours

The gym lights were already dimming when I spotted her again—Lila, the petite waitress from the café across the street who somehow always ended her shift here. Her tight black leggings hugged every curve of that firm, round ass like they were painted on, and the way it flexed as she bent over the weight bench sent a rush of heat straight to my cock. I'd been watching her for weeks, the tension building every time our eyes met. She knew it. I knew it. Tonight the place was almost empty, ten minutes till closing.

"Hey, Mark," she called out, straightening up with a towel slung over her shoulder. Her sports bra was damp with sweat, dark hair sticking to her neck. "You stalking me or what? Same time every night."

I wiped my hands on my shorts, pulse kicking up. "Just like my routine. Besides, watching you squat is better than any porn."

Lila laughed, low and throaty, then glanced around. The last trainer had already left. "Bold tonight, huh? Lock the door if you're serious. I've seen how you stare at my ass. Makes me wet just thinking about it."

My dick twitched hard in my shorts as I flipped the lock. She didn't wait—pushed me back onto the padded bench near the mirrors, straddling my lap. Her mouth crashed into mine, tongue sliding hot and eager. I grabbed two handfuls of that firm ass, squeezing the tight muscle, feeling it clench under my palms.

"Fuck, it's even better than it looks," I growled against her lips. "So round and hard. You do those squats just to tease me?"

"Maybe." She ground down on the bulge in my shorts, moaning softly. "Feel how tight it is? Spank it. I want you to."

I didn't hesitate. My hand cracked across one cheek, the sound echoing in the empty gym. Lila gasped, arching her back, pushing that perfect ass higher. "Again. Harder."

Smack. The flesh jiggled just enough before snapping back firm. I yanked her leggings down to her thighs, exposing bare skin—no panties. Her pussy was already glistening, shaved smooth and dripping. I slid two fingers along her slit, rubbing her swollen clit while my other hand kept kneading and slapping that juicy, athletic ass.

"Oh shit, yes," she panted, reaching back to spread herself wider. "Finger my pussy while you play with my ass. I've been soaked all shift thinking about your cock."

I pushed my fingers inside her tight heat, curling them against her walls. She rode them shamelessly, her firm cheeks bouncing against my wrist. The mirror gave me the perfect view—her flushed face, tits spilling from her bra, and that incredible ass rippling with every thrust of my hand.

"Get on your knees," I ordered, voice rough. Lila slid off, dropping to all fours on the mat, back arched deep so her ass pointed straight up. I shoved my shorts down, my thick cock springing free, already leaking precum. Gripping her hips, I rubbed the head along her wet folds.

"Put it in," she begged, looking back over her shoulder. "Fuck me doggy so you can watch my ass bounce. I want it deep."

I slammed in with one hard stroke, burying my cock balls-deep in her dripping pussy. The wet smack of skin on skin filled the room. Her walls clenched around me like a vice, hot and silky. I started pounding her fast, watching that firm ass ripple and jiggle with every brutal thrust. Each time I bottomed out, her cheeks clapped against my hips.

"God, your dick feels huge," Lila moaned, pushing back to meet me. "Fuck my tight cunt harder. Slap my ass while you wreck it."

I obliged, spanking her repeatedly until both cheeks glowed pink. The sting made her pussy flutter and squeeze even tighter. I slowed down, pulling almost all the way out before driving back in, savoring the way her slick juices coated my shaft and dripped down her thighs.

Switching it up, I pulled out and sat on the bench, stroking my glistening cock. "Come ride me reverse. I want that perfect ass in my face."

Lila stood on shaky legs, turned around, and lowered herself onto me. Her firm cheeks spread as my dick sank back into her pussy. She planted her hands on my knees and started bouncing, that athletic ass flexing and rolling in hypnotic circles. I grabbed it with both hands, spreading her wider so I could watch every inch of my cock disappearing between her lips.

"Fuck, I'm gonna cum," she whined, speeding up. Her breaths came in short gasps, body trembling. "Rub my clit—yes, like that. Don't stop spanking me."

I reached around, circling her swollen clit while my other palm cracked across her bouncing ass. Her pussy suddenly clamped down, pulsing wildly as she came hard, a gush of wetness flooding my balls. The sight of her firm cheeks quivering through her orgasm pushed me over.

"Shit, Lila—I'm cumming," I groaned. She kept riding through it, milking me until I exploded deep inside her, thick ropes of cum painting her walls. We stayed locked together, panting, sweat-slick skin sticking.

Finally she climbed off, cum trickling down her thigh. She pulled her leggings back up with a wicked grin, giving her ass one last playful smack.

"Same time tomorrow?" she asked, voice husky.

I laughed, still catching my breath. "Wouldn't miss it for the world."
