All Sexual Activity In This Story Is Between Persons 18+ Years Old
Horst Reiner stood in his underwear hunkered over eighteen-year-old Nanine Corbin's haunches. His shorter than average, but plenty stout, prick was stuffed thirteen centimeters inside her virgin vagina. She mewled softly as her tight tunnel collapsed and her inexperienced cunt muscles sucked his stalk. He held her ass firmly to his gonads while he pumped four hot semen shots to an unknown fate.
On the fifty-six-year-old Eastern Railways Company conductor's immediate right lay Nanine's twin, Nadine. She, too, was bound by her knee socks, bent in an 'L' over the standard double bed in the Wagon-Lit sleeper's main compartment, and was no longer a maiden. Like her sister, she was caught up by a glowing inner satisfaction that was stronger than any pleasure she had ever known. While Horst fucked Nanine, Nadine's overfilled pussy discharged previously deposited cum which was not already dedicated to a different higher purpose.
The maxim 'Waste not, want not' popped into Horst's head as saw his ejaculate turtle out from Nadine's trembling twat. Withdrawing from Nanine's sheath, he smiled at the pink-tinged jism threads festooning between her deflowered hole and his ruddy glans. As he shifted his feet a half-step to the right and centered himself between the teens, the fragile cum-bridge snapped. Two-thirds of the span fell and clung high in the crease where her left thigh joined with her cunt, while the rest drooped, then stuck to his elevated erection.
Reiner bladed the sticky strand, along with the twins' combined lubricants, from his steel-hard rail and shoved both his hands between their legs. Swiping his cupped palms upward, he graded their gashes then bathed their sphincters in the gathered grease. As he worked his thumbs increasingly around the starred apertures, new pleasure messages arrived and roused the girls from their fuzzy thoughts. They groaned responsively and pushed their bottoms back naturally to meet the interesting pressure.
Encouraged by their reactions, Horst dipped his fingers deep into the Corbins' cunnies and teased their G-spots. They greeted his digits with rippling grips and slathered him with fresh juices. Lowering his thumbs from their anuses, he diddled their clits with fast firm flicks. Sparks flew in their brains.
Flopping on the mattress like caught fish in a boat, Nadine and Nanine came copiously upon Reiner's hands. The chewed the bedding and wished their hands were free to claw whatever was reachable. Their drenched thighs gleamed like Lake Geneva in the late afternoon sun. The more they came, the more he grinned as he mercilessly threw extra fuel on their soul-fires.
Horst had so cleverly yoked together the twins necks in one of their stockings that, despite their violent movements, their faces stayed only millimeters apart. Nadine croaked hoarsely, "Mon Dieu, je continue Γ venir!"
Nanine hissed back, "Moi aussi! Encore et encore!"
Reiner judged from the sweat breaking on the girls' writhing backs that they were more than primed for their next lesson. Quickly, he returned to their assholes, flipped over his wrists and jammed his slick birds two knuckles deep in a single thrust. Predictably, they yelped, but then moaned softer notes as he withdrew to the base of his nails before pushing back into their rectums again. On his next cycle, he resumed massaging their little men's bald heads with his thumbs while he curled his fingers to tease their tight rear tunnels' floors.
The sisters squirmed and mewled. They bowed their spines, and abraded their breasts in the bedcovers while they clutched their gut muscles to keep the miraculous fingers trapped. Horst could not have been more pleased, and he said so. "Très bien, mes chéries! I only regret that I have but one cock! One of you will have to wait on the other!"
With that said, the conductor exited both anuses then positioned himself behind and above Nadine's lifted behind. Swiftly, before the gaping orifice could seal, he installed his hard dick's velvet knob. She opened her mouth in a wide 'O' and inhaled a great breath. While he inexorably compressed his fat fullness into her cavity, she let her air out like a leaking tire.
Nanine felt overcome by an inexplicable need as she watched her twin's facial expressions clearly display a state of thrilling wonder. She craned her neck and kissed into her blowing lips. Nadine more than welcomed the loving advance. She gulped hungrily and kissed back passionately.
Reiner laughed to himself as he watched the hand-bound girls struggle. Their knee sock collar helped, but it was obvious they were frustrated not to be able to embrace each other and lock themselves together as their sexual furies raged. He rocked his hips, pushed his prick a little deeper and then pulled out. Nadine groaned sorrowfully into her sister's mouth as she felt his dick disappear.
Quickly, Horst re-set himself over Nanine's waving ass. Reaching between his heavy stomach and her spread legs, he reloaded his left hand with her abundant lube and lathered his peg from base to tip. Then, as he had done for Nadine, he flattened his bulb against her shiny wet bunghole. While he squeezed himself home through the tight iris, he crooned, "Very good, Neenee. You were so patient. So good. Now it is your turn."
As Reiner's mushroom slowly slid, millimeter by millimeter, into her rectum, Nanine strained to hurry him. She wanted him now. She needed him now. She tongue-wrestled with Nadine while she thrust her butt backward to meet and consume the incoming mass.
Horst sensed Nanine's eagerness and pulled her hips up as he drove his dick down in a hard plunge. She came anew as his balls bumped her cheeks. The powerful fresh orgasm was an epiphany. Suddenly she had a new appreciation for how she had made Trang's uncle ejaculate so strongly and swiftly by twisting her finger in his ass while Nadine sucked his cock.
Reiner pulled back and then pushed to his limit again. Nanine snapped her head back and howled as a joyful thrill raced up her spine to her cortex. Nadine felt bereft. Not only did she no longer have anything filling her bum or her pussy, she now lost contact with her sister's sloppily salivating, but wonderfully intoxicating mouth.
