Late Night Plug

The gym was almost empty, just the low hum of the air conditioning and the faint clank of weights in the distance. I spotted her the second I walked in—Elena, my old classmate from ten years ago, now all lean muscle and sun-kissed skin in tight black leggings that hugged every curve. My cock twitched instantly at the sight of her round ass as she bent to adjust a mat, a tiny bulge at the base of her spine pressing against the fabric. Desire hit me like a freight train; the tension crackled between us before we even spoke.

"Hey... Mark? No way." She straightened up, wiping sweat from her brow, her sports bra damp between full breasts. Her eyes lingered on my chest, then dropped lower. "You still look like you could bench a truck. God, it's been forever."

"Yeah, Elena. Damn, you... filled out nicely." I stepped closer, voice low. The gym lights flickered as the front desk guy yelled that they were closing in twenty. "What are you doing here so late?"

She laughed softly, a husky sound that went straight to my groin. "Couldn't sleep. Needed to burn off some... energy." Her gaze flicked to my shorts, where my growing erection was impossible to hide. "Looks like you might need the same."

We moved to the empty stretching corner near the back lockers, the scent of rubber mats and clean sweat thick in the air. My heart pounded. She turned, arching her back slightly, and that little bulge caught my eye again.

"What's that?" I murmured, reaching out before I could stop myself, tracing the edge of her waistband.

Elena shivered, biting her lip. "A secret. Been wearing it all day... a butt plug. Keeps me wet and ready. Thought no one would notice at this hour." Her voice dropped to a whisper. "But you always did notice everything about me back in school."

The explicit heat surged fast. I pressed her against the padded wall, the gym's distant echo of a closing door making us both freeze for a second. "Show me," I growled softly.

She hooked her thumbs in her leggings and peeled them down just enough, revealing a sleek black silicone plug nestled between her firm, juicy ass cheeks. Her shaved pussy glistened below it, lips puffy and slick. "Fuck, Elena... that's so hot."

"Touch it," she breathed, pushing back against my hand. I gripped the base and gave a gentle tug, making her gasp. The gym's fluorescent buzz seemed louder now, every small sound risky. I circled the plug slowly, feeling her asshole clench around it while my fingers dipped into her dripping pussy.

"Oh shit... yes, like that." Her hips rolled, the wet sounds of her folds loud in the quiet space. I added a second finger, stretching her while twisting the plug. She moaned low, muffling it against her arm. "Mark, I've wanted this since we graduated. Fill me up... but keep it in."

I freed my throbbing cock, thick and veined, pre-cum already beading at the tip. Bending her forward over a stability ball, I rubbed the head along her slit, coating myself in her juices. The ball wobbled slightly under her weight, forcing her to balance as I pushed inside her pussy in one slow, deep thrust.

"Fuuuck," she hissed, her walls gripping me like velvet fire. The butt plug made her so much tighter, every inch of my dick feeling the pressure from the toy in her ass. I started moving, long deliberate strokes that made the ball creak softly. The gym's overhead lights cast long shadows, and the faint smell of her arousal mixed with rubber and metal.

"Quiet... or they'll hear," I whispered, one hand clamping over her mouth as I picked up pace. Her muffled cries vibrated against my palm. I reached around to rub her swollen clit in tight circles, feeling her tremble.

"Harder, Mark... make me cum with this thing inside me." Her ass jiggled with each thrust, the plug shifting deeper. I spanked her lightly, the smack echoing too loud, so I slowed again, grinding deep instead. The delayed build-up had us both sweating, breaths ragged.

She came first, pussy spasming wildly around my cock, juices squirting down my balls. The plug amplified every contraction, milking me until I couldn't hold back. I pulled out at the last second, stroking fast and painting her lower back and the base of the plug with thick ropes of cum. It dripped down over the toy, making it glisten.

We stayed like that for a moment, the gym now silent except for our heavy breathing. I helped her up, pulling her leggings back into place, the plug still firmly seated, my cum trapped against her skin.

"Stay the night?" she whispered, turning to kiss me softly, her fingers tracing my jaw. "We have ten years to catch up... and I want to feel you take this plug out next time."

I smiled against her lips, heart still racing. "Only if you wear it to breakfast."
