I Fuck with my Stepbrother while we were Home alone and he Cums inside my Pussy by Accident.

An eager, lonely stepbrother and his curvaceous stepsister are home alone, the house is silent, and the tension is palpable. He can't resist the urge to join her in the living room, where she's lounging on the couch. Her big, round ass is on display, and he takes his chance, sliding in behind her. She giggles, trying to play it cool, but her body is already responding to his touch. He starts kissing her neck, collarbone, and back, making her shiver with anticipation. She turns around, and they both know the rules of their secret game have been broken. They're about to cross a line they've never crossed before. He pulls her close, and she finds herself kissing him back, their lips meeting in a passionate embrace. He reaches down, cupping her big, juicy ass, and she moans softly into his mouth. He breaks the kiss, and she looks into his eyes, a mix of excitement and nervousness in her gaze. But she doesn't stop him as he lifts her up and places her on the couch, straddling him. He unbuttons his pants, freeing his hard cock, and she grins wickedly, licking her lips. She takes him in her hand, stroking him gently, before sliding him deep inside her wet, ready pussy. She rides him slowly at first, then faster, their bodies slapping together as they fuck. She leans back, taking him deep, and he groans with pleasure. He grabs her hips, pulling her down hard, and she screams in ecstasy. He can't hold back any longer, and she feels him get bigger, ready to explode. But they're not done yet. He flips her over, putting her in doggystyle, and she feels him slide back inside her. He fucks her hard, fast, and deep, and she can feel the heat of his release. He pulls out just in time, and she watches as he cum all over her big, juicy ass. But she's not done with him yet. She leans down, licking up his cum from her ass, tasting his salty, sweet nectar. He groans, and she smiles, knowing she's driven him wild. She climbs back on top of him, and he takes her again, this time cumming inside her pussy. She moans, feeling his hot cum filling her up. They both know this was a one-time thing, but it was incredible. They're exhausted, but satisfied, and they fall asleep in each other's arms, leaving their secret adventure behind them, for now.
