The overnight train from Delhi to Mumbai rattled through the dark countryside, its wheels clacking a steady rhythm that matched the heat building in Priya's body. She was 42, curvy and thick in all the right places, with heavy tits that strained against her thin nightie and a round ass that jiggled with every step. Her son Rahul, 22, and his best friend Arjun, also 22, shared the cramped AC sleeper compartment with her. Rahul had passed out on the upper berth after too many drinks, snoring softly.
Arjun couldn't sleep. He'd been staring at Priya for years, jerking off to thoughts of her thick thighs and the way her saree clung to her hips. Tonight she wore a loose nightie, no bra, nipples poking through the fabric. When she climbed down to use the bathroom, Arjun followed.
The tiny toilet was right there. He pushed the door open behind her, grabbed her waist, and spun her around. "Aunty, I've wanted this cock in you forever," he growled, yanking her nightie up. Priya gasped but didn't stop him. Her pussy was already wet from the long ride and the forbidden thrill. Arjun freed his thick, veiny dick—eight inches of hard meat—and shoved two fingers straight into her slick cunt.
"Fuck, you're dripping," he muttered, finger-fucking her hard against the wall while the train swayed. Priya moaned low, biting her lip so Rahul wouldn't wake. "Arjun, beta, this is wrong… but don't stop." He pulled his fingers out, sucked them clean, then bent her over the sink. One thrust and he buried his cock balls-deep in her married pussy. She was tight, hot, and soaked. He fucked her raw and fast, hips slapping her ass with wet smacks, the train's motion adding extra force to every stroke.
Priya pushed back, meeting every thrust. "Harder, fuck your friend's mom like a slut," she hissed. Arjun pounded her, one hand squeezing her swinging tits, the other rubbing her clit in rough circles. Her juices coated his shaft and ran down her thighs. They came quick and messy—her cunt clamping down as she squirted a little, him flooding her with thick ropes of cum that leaked out around his cock.
They cleaned up fast and slipped back to the berths. But Arjun wasn't done. An hour later, while Rahul slept on, he climbed into Priya's lower berth. She was waiting, nightie pulled up, legs spread.

This time it was slower but still filthy. He ate her cum-filled pussy first, tongue lapping his own load and her juices, then flipped her onto all fours and mounted her again. The bed creaked with each deep thrust. "Take it, aunty. Your son's friend owns this pussy now." Priya reached back to spread her ass cheeks, letting him watch his cock disappear into her. She came again, biting the pillow, while Arjun dumped another load deep inside her.
By morning the compartment smelled like sex. Rahul stayed asleep through it all. Priya and Arjun shared one last quickie in the corridor when the train slowed at a station—him bending her against the window, fucking her standing up until she milked him dry once more. As the train pulled into Mumbai, Priya whispered, "Next trip, we do it with Rahul awake." Arjun just grinned, already hard again at the thought. The ride had only just begun.
