Every week, I board the TGV from Lille to Paris in first class. Usually half-empty at this hour, no vis-à-vis. But today, my suitcase claims his reserved seat. ‘Excuse me, that’s my spot,’ he says. Tall, forties, handsome brunette with direct brown eyes. I apologize, stand to move it. Our hands brush on the handle—his warm, mine cool. Train jolts over switches; I stumble into him. Musky cologne, muscled frame. His hand steadies my hip—electric shock. He lifts the bag effortlessly overhead. We settle. I flip a magazine for cover, steal glances. Clean-shaven jaw, white shirt hugging pecs, gray suit. About 6 feet. He pulls out his laptop, types. Our eyes meet; I blush like a kid caught staring. ‘Know what I’m writing?’ he asks. ‘It’s about us.’ Heart races. ‘I felt you tremble earlier. Something passionate, short fling ahead. Feel it?’ His fiery gaze pins me. Tailored skirt suit, short hem, sheer blouse hinting lace bra. Thigh-highs, matching thong. Heat floods my core, soaking me. Speechless. ‘Close your eyes, let go.’ Wagon near-empty. I obey. His socked foot nudges my knees apart. I tense, reopen eyes—his smile reassures. ‘Alone here. Trust me.’ Eyes shut, foot insists. Knees part. Warms my thighs over stockings, then bare skin. Presses my pussy through thong. Stays there. Breath quickens. Toe finds clit, strokes up-down. Floodgates open; juices drench panties, his sock. First orgasm hits; I bite lip. Foot covers fully again. ‘Tickets, please.’ Controller looms. I’m slid forward, skirt hiked, thigh-high welts visible, legs spread, his foot on my crotch. He hands his ticket, punched. Controller stares, hypnotized. Mine trembles out—punched. Wink to him, gone. ‘Follow me.’ Hand extended, wet sock visible. I smooth skirt, take it. Cross wagon to tiny toilet. Door shuts; he backs against it. Pulls me back-to-chest. Hard bulge grinds my ass. Tailor jacket unbuttoned; he undoes blouse slow. Right hand pins my belly. I grip his ass cheeks, arch back. Bra down—brown areolas, stiff nipples. Fingers tease, roll peaks. Fire ignites. Guide his hand to my mound. Skirt up: thigh-highs, lace thong. Left hand kneads tits; right dives in, fingers through bush, into sopping pussy. Thong to mid-thigh. Bare ass on his pants; cock nests in crack. Three fingers plunge deep; thighs slick. Mirror shock: bourgeois me, exposed, offered. Fingers to clit—perfect rhythm. Hips buck; second orgasm crashes. I cry out. Knocks at door—ignored. I slump on seat, thong up. ‘Fantasy fulfilled?’ His voice velvet. Undoes his belt; pants drop. Low-rise briefs down. Thick cock, veined, rigid. Stroke, expose purple head. Eyes lock till his close. Lick shaft, balls, swirl glans. Saliva coat; deep throat. Finger his ass with my juices—prostate hit. He grips neck, floods my throat. Pulsing jets; I cum too, legs wide. Kiss deep; cock stirs. He strips me nude save stockings, heels. Admires. ‘Gonna fuck you.’ Legs wrap him; penetrates deep, balls-deep. Slow thrusts rub walls. Third orgasm quakes me. Down doggy on toilet lid. Guides cock in pussy; lubes ass with juices. Fingers stretch—three deep. ‘Gonna sodomize you.’ Withdraws; glans pops anus. Slow entry, full. Pounds hard; I push back. ‘Cum in my ass!’ He erupts; massive orgasm wrecks me. Collapse in arms, kiss. Dress hasty—no panties, his souvenir. Wipe pussy. Final kiss. Exit casual; phone guy stares. Back to seats. Suburbs flash. Eyes meet, smiles. Unknown lovers. Gare du Nord: descend, part amid suits. Breeze teases bare pussy. Husband waits. ‘Good trip?’ ‘Slept great.’ Secret forever.
