The Trainer’s Mistress

The office party was in full swing, the hum of chatter and clinking glasses filling the penthouse, but all I could hear was the thud of my own pulse. She stood by the floor-to-ceiling windows, a glass of champagne in her hand, wearing a black dress that hugged every curve like it was painted on. Mia. My trainer. The woman who’d spent three months putting her hands on my body, correcting my form, pushing me past my limits—and who’d just texted me from across the room: *“Meet me by the supply closet. Now.”*

I slipped away from my coworkers, my tie suddenly too tight. The hallway was dim, and the closet door was ajar. I barely got inside before her hand clamped over my mouth and shoved me against the wall.

“You’ve been staring at me all night,” she whispered, her breath hot on my ear. “Don’t think I didn’t notice.”

“Mia, I—” My voice cracked as her knee pressed between my legs.

“Shut up, Daniel.” She pulled back just enough to look at me, her eyes dark and playful. “You think I put all that work into your body for nothing? I want to see what it can do.”

Her hand found my belt, unbuckling it with practiced ease. I was already hard, straining against my boxers, my cock twitching as her fingers wrapped around it. She stroked me slow, deliberate, her thumb circling the head until I was leaking.

“God, you feel even better than I imagined,” she murmured, dropping to her knees. The sight of her—this fierce, beautiful woman who barked orders at me every morning—kneeling in front of me made my head spin. She took me in her mouth without hesitation, her lips stretching around my shaft, her tongue flat and greedy as she swallowed me deep.

I groaned, my hand finding her hair, not pushing, just holding. She looked up at me, eyes watering, and moaned around my cock like she was savoring it. The wet heat of her mouth was overwhelming, her throat working as she took me all the way in, her nose brushing my pelvis.

“Fuck, Mia,” I gasped.

She pulled off with a wet pop, licking her lips. “Not yet, baby. I want you inside me.”

She turned around, bending over a stack of boxes, her dress bunched around her waist. Her thong was a thin black string, already soaked. I tugged it aside and ran my fingers through her slick folds, making her shiver.

“You’re so wet for me,” I said, my voice rough.

“That’s because you’ve been teasing me for months with those tight shirts and those fucking squats,” she shot back, pushing her ass against me. “Now stop talking and fuck me.”

I didn’t need to be told twice. I lined up and slammed into her, her pussy clenching around me like a fist. She cried out, a sharp, breathy sound that I wanted to hear again and again. I pulled out almost all the way and drove back in, setting a rhythm that had her gripping the boxes, her knuckles white.

“Yes, like that,” she panted. “God, you’re so deep.”

My hands found her hips, pulling her back onto me with every thrust. Her ass slapped against my thighs, the sound filling the tiny closet. I leaned over her, my chest pressed to her back, my mouth at her ear.

“You like being my dirty little secret, Mia? My mistress?”

She laughed, breathless. “You’re the one who’s been my good boy all year. Now fuck me harder.”

I did. I grabbed her hair, yanking her head back as I pounded into her, her moans turning into desperate whimpers. The pressure built in my gut, my balls tightening, and I knew I wasn’t going to last.

“I’m close,” I grunted.

“Cum inside me,” she begged, her voice raw. “Please, Daniel, I need it.”

That did it. I buried myself to the hilt and came with a groan, my cum flooding her, hot and thick. She shuddered around me, her own orgasm rippling through her pussy, milking me dry.

We stayed like that for a long moment, panting, sweaty, tangled in the dim light of the closet. Finally, she straightened up, pulling her dress down, and turned to face me. Her lipstick was smeared, her hair a mess, and she was grinning.

“Not bad for a guy who couldn’t do five push-ups when we started,” she said.

I laughed, a real laugh, light and easy. “Not bad for a trainer who’s supposed to be professional.”

She leaned in, kissing me soft and quick. “Meet me at the gym tomorrow. Same time. I have more… exercises for you.”
