Late Night Stretch

The hotel conference room still smelled of sweat and lavender oil when everyone else had left. I stayed behind, rolling up my mat slowly, watching my yoga teacher, Lena, as she bent to adjust the thermostat. Her black leggings hugged every curve of her firm ass, the thin fabric disappearing between her cheeks. My cock had been half-hard the entire class, and now the tension crackled between us like static.

Lena glanced over her shoulder, her dark ponytail swinging. She was in her mid-thirties, toned from years of teaching, with sharp green eyes that always seemed to see too much.

"You didn't have to stay, Mark," she said, voice low. "Business trip got you that restless?"

I swallowed, stepping closer. "Something like that. Your class... it didn't exactly relax me tonight."

She straightened, turning to face me. A slow smile curved her lips. "I noticed. You've been staring at my ass for the last twenty minutes of downward dog."

Heat flooded my face, but I didn't deny it. "Guilty. It's fucking perfect, Lena."

Her breath hitched. She closed the distance, fingers brushing the front of my gym shorts where my cock strained against the fabric. "Then maybe we should do something about that tension. Private lesson. No one else is using this room tonight."

Before I could answer, she pulled me into a kiss, her tongue sliding against mine, tasting like mint and desire. My hands grabbed her waist, sliding down to squeeze that juicy ass I'd been obsessing over. She moaned into my mouth, grinding against my thigh.

We broke apart, breathing hard. Lena's eyes sparkled with mischief. "Get the mats back out. I want you to watch me stretch first."

She peeled off her tank top, revealing a simple black sports bra that barely contained her perky tits. Then she turned, dropping into a deep lunge, ass pushed high. I yanked my shorts down, my thick cock springing free, already leaking at the tip.

"Fuck, Lena... you're killing me."

"Good," she whispered, looking back at me. "Because I want that big cock in my ass tonight. Been thinking about it since you walked into my evening class last week."

My pulse hammered. She reached back, tugging her leggings and thong down in one smooth motion, exposing her smooth, shaved pussy and the tight pink pucker above it. The scent of her arousal mixed with the room's lingering oil.

I dropped to my knees behind her, hands spreading her cheeks. "You sure? I don't have lube."

She laughed breathlessly, arching her back. "Use the massage oil from the cabinet. And your tongue first. Get my asshole nice and wet, Mark. I love it sloppy."

I grabbed the bottle, drizzling warm oil over her crack. It trickled down, glistening on her skin. Leaning in, I dragged my tongue from her dripping pussy up to her tight anus, circling the rim. She gasped, pushing back against my face.

"Oh shit... yes, just like that. Lick my ass, baby. Deeper."

I groaned, the musky-sweet taste driving me wild. My tongue pressed inside her tight ring, fucking her slowly while my fingers found her swollen clit, rubbing firm circles. Lena's moans echoed off the walls, her thighs trembling.

"Fuck, your tongue feels so good in my ass... don't stop. Get it ready for that thick cock."

After minutes of rimming her, her hole was shiny and relaxed. I poured more oil on my cock, stroking it slick. Lena stayed on all fours, looking back with hungry eyes.

"Do it. Fuck my ass, Mark. I want to feel every inch stretching me."

I pressed the fat head against her pucker, pushing steadily. Her asshole resisted for a second, then popped open, swallowing the head with a wet sound. We both groaned.

"Goddamn, you're tight," I hissed, gripping her hips.

Lena pushed back, taking another inch. "Deeper... fuck my ass harder. I can take it."

I started thrusting, slow at first, watching her ring stretch around my shaft. The oil made obscene squelching noises with every stroke. Her pussy dripped onto the mat below. I reached around, fingering her clit while I picked up speed, pounding deeper until my balls slapped her wet folds.

"Yes! Fuck my asshole... just like that. You're so deep, Mark. Shit, I'm gonna cum already."

Her body clenched, her ass pulsing around my cock as she came hard, a gush of wetness spraying from her pussy. I didn't stop, driving through her orgasm, the heat and pressure almost too much.

I pulled out suddenly, flipping her onto her back on the mat. "Want to see your face when I fill your ass."

Lena spread her legs wide, pulling her knees to her chest, exposing everything. I slid back into her ass in one smooth thrust, watching her tits bounce with each hard pump. She reached down, rubbing her clit furiously.

"Harder... pound my tight ass. I want your cum deep inside me."

Sweat slicked our skin, the room filled with the slap of flesh and her filthy moans. I felt my balls tighten. "I'm close, Lena. Gonna cum in your ass."

"Do it. Fill my asshole with your hot cum!"

With a guttural groan, I buried myself to the hilt. My cock throbbed, pumping rope after rope of thick cum deep into her bowels. Lena cried out, cumming again, her ass milking every drop from me.

We stayed locked together, panting. She smiled lazily, clenching around my softening cock.

"Best business trip stretch I've ever had," she whispered.

I kissed her, still buried inside. "Same. Think we need another private session tomorrow night?"

"Only if you promise to fuck my ass again."

I grinned. "Deal."
