Sister Sitting: Part One

After a night that left her wrecked and glowing, Carter Cruise figures she might finally grab lunch with a friend. Her phone buzzes. Her mother on the line: Piper needs watching. Carter says no flat out. Piper’s eighteen; she can look after herself. The order is clear anyway, so Carter drives home annoyed, no clue what waits upstairs. She climbs the steps calling Piper’s name and gets only the sound of soft, wet pleasure. Carter stops outside the closed door. Masturbation? She gave up lunch for a chronic masturbator. A smile creeps across her mouth. Maybe this is the perfect chance to bond. She cracks the door. Piper lies naked on the bed, one hand working beneath cotton panties. Carter steps closer, notices the quick hitch in the girl’s breath. No hurry. No words. Carter leans down and takes Piper’s mouth in a slow, warm kiss. Piper answers without hesitation, bare chest rising, nipples tight. Carter gathers one small breast in her lips, sucks until the flesh glistens, then licks the other until Piper’s thighs spread wider. Fingers follow. Carter brushes over soaked cotton, then slips inside the panties and presses the swollen clit. A single finger sinks deep, draws back, sinks again, rhythm steady and firm. Piper arches, breathless. She reaches up, tugs Carter’s underwear free, lifts the damp thong to her face, and presses the scent over her own mouth like a blindfold. The scent of Carter on her tongue and Carter’s hand thrusting harder makes her moan into silk. Carter pins Piper’s ankles, kisses each toe, then folds her step-sister nearly in half. With lips parted she seals her mouth over Piper’s dripping cunt and licks deep, tongue dragging over velvet folds, tasting every slick corner. She flattens her tongue over the swollen clit and sucks until Piper’s legs tremble. The two scissor together, slick heat rubbing slick heat, thighs locked, hips bucking. Carter grips Piper’s ankle, meets her gaze and whispers one command: come with me now. The room fills with the soft slap of skin on skin, quickening breaths, a shared cry breaking at the same instant, bodies grinding hard until the edge slips and they fall over together.
