Friend's Wife on the Night Train

The moment I stepped into the dimly lit sleeper car, my cock twitched at the sight of her. Lena, my best friend Mark's wife, stood there in tight black yoga pants that hugged every curve of her juicy ass, her cropped tank top barely containing those full tits. The night train from the city to the coast was nearly empty, just the low hum of the rails and the faint scent of her vanilla lotion mixing with the stale air. Tension crackled between us instantly—her eyes locked on mine with that knowing smirk, like she could read every filthy thought I'd buried since her evening yoga classes started months ago.

"Hey, Alex," she said softly, voice low and teasing as she closed the compartment door behind me. "Mark mentioned you might be on this train. Small world, huh? Or maybe not so small."

I swallowed hard, my dick already half-hard in my jeans. "Lena... shit, I didn't expect to see you here. What are you doing on the night train alone?"

She shrugged, leaning back against the bunk, her nipples poking through the thin fabric. "Last-minute work thing. Mark's stuck at home. But I've been thinking about you since class yesterday. The way you stare at my ass when I demo downward dog."

Her words hit like a spark. I closed the distance in two steps, grabbing her hips and pulling her against me. "You've noticed that? Fuck, Lena, you're my friend's wife. This is dangerous."

She laughed breathily, grinding her mound against my growing bulge. "Dangerous turns me on. And Mark doesn't fuck me like I need anymore. I've seen that big cock of yours tenting your shorts in class. Touch me, Alex. Right now."

The explicit heat exploded fast. I yanked her tank top up, freeing her heavy tits, and latched my mouth onto one hard nipple, sucking greedily while my hand dove into her yoga pants. No panties—her pussy was already soaked, shaved smooth and slick. My fingers slid between her wet folds, circling her swollen clit as she moaned loud enough to echo in the rattling compartment.

"Oh god, yes... finger my pussy," she gasped, her hand fumbling with my zipper. She pulled out my thick cock, stroking it firmly, thumb smearing the precum leaking from the tip. "It's so big. Bigger than Mark's. I want it inside me."

I shoved her pants down to her ankles in one rough tug, spinning her around to bend her over the narrow bunk. Her juicy ass jiggled as I spread her cheeks, staring at her dripping cunt and tight little anus winking at me. Without another word, I lined up and thrust my cock deep into her pussy in one hard stroke, balls slapping against her clit.

"Fuuuck!" Lena cried out, pushing back to take every inch. "Pound me, Alex. Fuck your friend's wife like you own this slutty pussy."

The train's rhythmic clack-clack matched my thrusts as I gripped her hips, slamming into her wet heat over and over. Her walls clenched around me, juicy sounds filling the air with every deep plunge. I reached around to rub her clit furiously, feeling her tremble.

"Harder... don't stop," she begged, voice breaking. "I'm gonna cum already—oh shit!"

Her orgasm hit like a wave, pussy squirting a little around my cock as she shook, moaning my name. I didn't slow down, flipping her onto her back on the bunk instead. Her legs wrapped around me as I drove back in, missionary now, watching her tits bounce with each powerful fuck.

"You like cheating on him with me?" I growled, pinching her nipples.

"Yes... god, yes. Fill me up. Cum in my pussy, Alex. I want to feel it leaking out all the way to the coast."

Sweat slicked our skin, her vanilla scent mixing with raw sex smells. I pounded faster, the bunk creaking dangerously. She came again, nails digging into my back, her cries turning into whimpers. The pressure built until I couldn't hold it—my balls tightened and I buried myself to the hilt, shooting thick ropes of hot cum deep inside her spasming cunt.

We collapsed in a sweaty tangle as the train rocked on, my cock still twitching inside her. Lena kissed me lazily, whispering, "That was just the start of the ride. Mark never has to know."

I grinned, already feeling my dick stir again against her thigh. The night was long, and so was this forbidden tension.
