Luggage stowed in the hold, cabin key clipped to my bikini. This charter catamaran felt like perfect transit anonymity—sailing strangers, harbor lights fading, Paris crew chatting like old mates. I slide onto the bench next to Yan, his easy grin pulling me in. Hélène pivots my face with one hand, plants a firm kiss. Lingering. Dinner’s basic but loaded: fresh fish, rice, wine flowing. Coffee follows in the saloon, Parisians griping winter blues. Hélène kicks her feet up opposite, inches from my thigh. Her toe grazes my pants—accidental? Calculated brush again. Heat rises. Embarrassed, I bolt forward, flop on the trampoline netting, back to a bubble porthole. Cool sea air rocks the boat gently. Inside noises: zippers, laughs, group vanishing to bunks. My backpack slumps nearby, passport safe inside. Light flares from the porthole behind—right above Hélène’s cabin. Peeking down, despite myself. She drops her dress fast, pool at her feet. Just plain panties hugging that curve. Shakes out dark red hair over bare shoulders. Breasts lift, taut, begging the gaze. I’m glued. She sits, squeezes lotion on her belly. Hands spread it wide—thighs, calves, ankles. Bends forward, back arched naked. Then cups her tits, kneads slow. My heart hammers my chest. She flips off the main light. Nightlight glows. Slides panties down. Naked on white sheets, feet braced on bulkhead. Legs part slight, dark bush stark against pale hips. Hands roam. Fingers circle big areolas, tease nipples hardening. One hand dips low, skirts pubis, dives inner thigh. Legs fold, feet together, then wide. Hips buck slow. Fingers meet at her core—wet, lost in slick folds. I clench thighs, fighting the ache. Her fingers glisten, plunging pussy, ass lifting like chasing more. Sweat beads. I’m soaked, fumbling pants open. Thumb shifts panties, fingers sink into my dripping lips. Stroke hard, eyes locked below. She flips to knees, plump white ass up. Fingers back, then rear—spreading cheeks, dipping anal wet. Ass thrusts toward the cabin ceiling, meter from my face. I crave touching that skin. Orgasm hits me quiet, shuddering on netting. Eyes snap open: she’s on back, mouth gasping, body quaking. Grabs sheet, grinds clit final. Cums biting lip, eyes piercing up—like at me. I jerk back, heart pounding. Slip below deck silent, pause at her door. Knock? No. Into my cabin, strip naked, slide under sheet still slick. Sleep claims me, pussy throbbing. Dawn check-out: hand over key at the dock office. Bags dragged to taxi. Boat sways empty, that porthole memory burning as we speed to the airport. One-night transit sin, gone by takeoff.
